Discovered by a Rice Rivers Center researcher while trawling the James River, the five-foot-long 19th century anchor will go on display overlooking the river

VCU researcher discovers 19th-century anchor while hunting for juvenile sturgeon

February 27, 2019

By Brian McNeill, Univesity Public Affairs

In search of juvenile sturgeon, Virginia Commonwealth University researcher Matt Balazik, Ph.D., was pulling a trawl along the bottom of the James River near the VCU Rice Rivers Center when the large conical net he was pulling behind the boat hit a snag.

It’s not unusual for the trawl to get stuck. But the reason for this particular snag was highly unusual. It was stuck on a 5-foot-long, wrought-iron anchor that most likely once belonged to a two, three or four-mast commercial cargo vessel that traversed the James River during the 1800s, possibly prior to the Civil War.

“It was a pleasant surprise because usually when we snag something big it turns out to be a tree or large piece of metal,” Balazik said. “Even though technically this is just an old piece of iron that we had to pull up by hand, and caused damage to our gear that took days to repair, I’m very happy we snagged it.”

Students from the Steward School look at the bagged oyster shells at the Rice Rivers Center

Rice Rivers Center part of The Steward School's Community Week

February 19, 2019

Cary Jamieson, director of the Bryan Innovation Lab at The Steward School and a VCU Rice Rivers Center Board of Trustees member, organized an experiential learning program for students with area environmental partners as part of the Steward’s Community Week. The group of seventh graders immersed themselves on and along the river, canoeing, observing animals in their natural habitats, and learning about the James River and the importance of wetlands.

The Rice Rivers Center hosted the students for a day, where they were able to explore the grounds of VCU’s river campus and environmental field station, and participate in bagging oyster shells for the Virginia Oyster Shell Recycling Program (VOSRP). Cindy Andrews, VOSRP Richmond Region Coordinator, was on-hand to explain the process of oyster restoration and reintroduction in the Chesapeake Bay and how the students were a part of that process. Virginia Master Naturalist volunteers from the Riverine chapter also were on hand to guide the students in the bagging recycled oyster shells for future sanctuary reefs. The students wrote messages on the oyster shells that are now curing at Rice Rivers Center in those bags, awaiting to be seeded with spat and returned to the Chesapeake Bay.

Adult white ibis with a brood in Virginia.

White ibis explode in Virginia

January 17, 2019

By Bryan Watts, Center for Conservation Biology

Some species creep forward across the landscape.  They fortify their troops and slowly take ground with the restraint of a calculated military campaign.  Other species jump with wild abandon across the landscape, consuming new ground and seemingly unconcerned about the basic supports that will be needed to sustain their advance.  White ibis fall into the latter category.  Unconcerned with species norms, white ibis have been documented to pick up entire colonies supporting tens of thousands of pairs and move completely in a single year.  What triggers these moves is unclear but they have left unsuspecting graduate students with no date to the prom and thesis projects citing “unanticipated events.” 

In the beginning, the white ibis story in Virginia appeared to be a dud.  Breeding was confirmed on Fisherman Island during the summer of 1977, but the species sat idle within this toe hold for more than 20 years.  We thought that they had been constrained by ecological requirements during early brood rearing that would limit colonization of heronries on the offshore barrier islands.  During the 1980s, research in South Carolina had shown that salt glands in young ibis did not develop until three weeks of age, forcing adults to move long distances to mainland sites to gather fresh-water prey until the young were able to tolerate their favorite but salty fiddler crabs.  Distance to the mainland might limit the formation of the more isolated colonies and hold the species in the state to curiosity status.  But in the early 2000s, small numbers colonized the Cobb and Wreck island heronries in a breakout move that would foretell the future.  

Over the past decade, the white ibis has become the most visible wader in the marshes throughout the Delmarva seaside.  For those of us accustomed to seeing the elegant, well-mannered flocks of snowy egrets, little blues and tricolors coming and going from their usual tide pools and ponds, the bold entry of ibis into the area has been a shock to the system.  They appear to be everywhere.  The most consequential development that appears to have ignited the population has been the colony along the Chincoteague Causeway.  Whatever the cause, the Virginia population has exploded, increasing from less than 400 pairs in 2013 to more than 1,500 pairs in 2018.  Given the demographics, this explosion could not have been driven by good productivity alone but represents a flow of birds into the state from populations to the south.  We should expect further expansion in Virginia and likely states to the north over the next few years.

Moving woodpeckers 4

January 16, 2019

By Bryan Watts, Center for Conservation Biology

For the fourth consecutive year, CCB and a multi-state, multi-agency coalition rallied to capture red-cockaded woodpeckers from source populations in the Carolinas and Virginia for reintroduction within the Great Dismal Swamp National Wildlife Refuge (GDSNWR).  The objective continues to be the establishment of a second viable breeding population in Virginia.  As with all of the past translocations, a large number of man days was required during the late summer and early fall to identify candidate birds along with their backups and backups to backups, identify roost trees so that the birds could be captured, and then roost them again for confirmation during the run-up to movement night. 

Eight hatch-year woodpeckers, including four males and four females, were moved during two nights.  Four birds were moved from Carolina Sandhills National Wildlife Refuge in South Carolina and two birds were moved from Palmetto-Peartree Preserve in North Carolina on 18 October. Two birds were moved from Piney Grove Preserve in Virginia on 7 November.  All birds were placed in artificial cavities and released the following morning at dawn.  All birds emerged fine and interacted with other woodpeckers.  In all, 36 woodpeckers have been meticulously monitored, captured, transported, and ultimately released from artificial cavities within the refuge since 2015.  All birds have been released successfully.

Update on the status of GDSNWR woodpeckers:

CCB biologists and refuge staff began a survey of woodpeckers on the GDSNWR in early December 2018.  The survey systematically roosted all recruitment clusters and artificial cavity trees over a period of several days and identified all birds using the sites.  2018 was a reasonable retention year, as three of the eight birds that had been moved earlier in the fall found roosting.  The 11 birds identified included four males and seven females setting up the possibility of four breeding pairs for the spring.  We will conduct another headcount in April to assess who is still standing as the birds move into the breeding season.

 

Ipswich sparrow just after banding. Band combination is Left- Blue-Red, Aluminum, Right- Pink-blue-red.

Have you seen me?

January 16, 2019

By Bryan Watts and Chance Hines, Center for Conservation Biology

The Center for Conservation Biology is asking bird watchers to be on the lookout for and report banded Ipswich sparrows.  The Ipswich sparrow is a specialized subspecies of the savannah sparrow that spends its entire life cycle within the narrow ribbon of dune habitat along the Atlantic Coast. The entire population breeds on Sable Island off the coast of Nova Scotia and winters along the coastal dunes primarily from the Carolinas through Massachusetts.  Birds are being marked as part of a collaborative investigation of demography.  Winter mortality is believed to be the principal limiting factor that regulates the population.  Parks Canada, Dalhousie University, and Acadia University are investigating breeding ecology on the Sable Island breeding grounds, marking birds to estimate survival, and using nanotags to study migration ecology.  The National Park Service and CCB are marking birds on the winter grounds to better understand patterns in winter survival and habitat use. 

Several hundred birds have been banded with unique combinations of color bands so that individuals may be distinguished and tracked through time.  A bi-color band has been paired with an aluminum band on one leg to indicate location of banding.  To date, blue/red and yellow/orange have been used during winter from North Carolina through Delaware and a yellow/green band has been used in New Jersey.  White/red and white/black bi-color bands have been used during the breeding season on Sable Island.  In all cases, the opposite leg has been banded with three color bands. 

 

We are requesting that bird watchers record: 

  1. Date and location of observation.
  2. Band combination – which bands on which legs and in what order read from top to bottom.  Example – Left leg: Blue/Red bi-color over Aluminum, Right leg from top to bottom Red-Yellow-White.
  3. Observer or observers present. 

Ipswich sparrows spend most of their time foraging or running along the ground making it difficult to read band combinations.  Photographs are helpful in obtaining and confirming band resights.

 

Please report resights and photos to chhines@wm.edu and ipswichsparrows@gmail.com.

Vials of blood collected as part of a collaborative effort between CCB and the National Park Service to monitor contaminant exposure for bald eagles

Clean blood for eaglets within lower Chesapeake Bay

January 15, 2019

By Bryan Watts, Center for Conservation Biology

Between 2016 and 2018 CCB in partnership with the National Park Service collected blood samples from 25 eagle broods distributed throughout the lower Chesapeake Bay to measure their exposure to environmental contaminants.  Exposure to key contaminants during the 1940s and 1950s is believed to have caused the population crash in the Bay and by the early 1970s levels in addled eggs were some of the highest recorded throughout North America.  The recent effort was a periodic “checkup” to monitor exposure for breeding pairs under the care of the park service.

Blood samples were analyzed for a range of contaminant classes including heavy metals (cadmium, lead, mercury), polychrlorinated biphenyls (PCBs – 91 congeners) and organochrlorine  pesticides (OCPs – 11 compounds).  Blood concentrations of heavy metals were generally low and varied between metals examined.  Cadmium did not exceed the level-of-detection for any sample.  Detection frequencies for Lead and Mercury were 86 and 100% respectively.  Lead concentrations were low and no sample exceeded the level believed to represent background for raptors.  Blood concentrations of mercury were toward the lower to middle range of values reported from other studies of nestlings.  Broods reared around lakes or tidal-fresh reaches of tributaries had higher concentrations of mercury than broods reared around high-saline waters.  This is consistent with studies of eagle nestlings elsewhere within the breeding range.  No samples approached the general threshold believed to result in possible reproductive impacts.  Total PCB concentrations estimated during this study were on the low end of values reported from other regions.  A cluster of the highest values were found within the lower James River.  However, the highest values represented approximately 10% of the threshold suggested for reproductive impairment and 50% of the threshold suggested for no-observed-adverse-effect-level.  Total OCP concentrations were lower than those reported from most other populations.  p,p'-DDE was the most widespread pesticide compound and accounted for 93% of the total OCP values.  Concentrations of  p,p'-DDE were all below the level suggested for reproductive impairment and below the no-observed-adverse-effect-level for productivity. 

Due to the endless parade of possible man-made products that may one day find their way into the Chesapeake Bay, vigilance for contaminants will always be a key component of management moving forward.  However, the results of the blood tests conducted over the past three years are good news for the bald eagle population and for the improving health of the Chesapeake Bay.

CES M.S. graduate accepts position at U.S. EPA

December 13, 2018

Positions with the United States Environmental Protection Agency are always coveted, and often very hard to land. Meet Lindsey Hendrick, the U.S. EPA’s newest biologist, and recent Virginia Commonwealth University graduate. 

Hendrick received her Master of Science from the Center for Environmental Studies in spring 2018. Her travels to Panama to study the prothonotary warbler as part of Dr. Catherine Viverette’s  “Team Warbler”, and her participation in Dr. Daniel McGarvey’s Inforgraphics class provided Hendricks different experiential learning opportunities to complement her already impressive educational resume. 

Headquartered in Washington, D.C., Hendrick is assigned to the Science Information and Analysis Branch of the Biological and Economic Analysis Division, which is a part of the Office of Pesticide Programs. This particular branch is responsible for monitoring pesticide use and usage analysis. As an EPA biologist, she will be assessing the quality of data submitted by organizations that have applied to register a pesticide with the EPA. Once the analysis is complete, the data will be used for risk assessment.

For the past eight years, Matt Balazik, Ph.D., and other researchers from the Rice Rivers Center at Virginia Commonwealth University have conducted trawl surveys in the James River in hopes of finding Atlantic sturgeon, the once-plentiful ancient fish that was listed as an endangered species in 2012.

During that time, Balazik and his peers have identified more than 600 different adult sturgeon. Among the hundreds of thousands of fish they found on their research trips, however, not once did they ever spot any baby sturgeon — and only twice did they find any juveniles of the species.

Then, last week, baby sturgeon started showing up in researchers’ nets. In the course of a week, Balazik and his fellow researchers identified 24 baby sturgeon during a series of especially productive trips on the river.

Taking root: Project to plant trees connects VCU and Carver

November 2, 2018

 

A project to plant dozens of trees this month in Carver will make the neighborhood a greener and more walkable community, while offsetting the carbon footprint of Virginia Commonwealth University as the trees grow.

The Carver Tree Project, the pilot project of the Urban Forestry Collaborative, has brought together resources from VCU, nonprofits and state agencies to plant and maintain 75 trees in the neighborhood, located just north of VCU’s Monroe Park Campus. VCU will be the first university in Virginia, and one of the first in the nation, to claim carbon offset credits for the new trees under a peer-reviewed program developed at Duke University.

2018 Shell-Raiser's Shindig benefits VOSRP

November 2, 2018

A beautiful fall day framed the 2018 Shell-Raiser’s Shindig, which took place October 21 at Libbie Mill-Midtown.  A record number of guests enjoyed Virginia oysters, dishes from some of the best chefs and suppliers in the state, and a wide-range of local beverages.  Proceeds from the Shindig generates a significant portion of funding to support VCU's oyster restoration initiative, the Virginia Oyster Shell Recycling Program (VOSRP)Due to success of this event and from the generosity of our partners and sponsors, we will ensure we continue to grow the VOSRP to help restore the Chesapeake Bay, provide educational opportunities and to engage our community in active restoration.

The VOSRP annually recycles approximately 125,000 pounds of waste shell. That shell is age-cured at the VCU Rice Rivers Center for up to a year, hauled to Gwynn’s Island where it is seeded with juvenile oysters at our public-private partnership spat setting facility and then returned to the Chesapeake Bay on reef restoration projects in the Piankatank and Rappahannock Rivers. The VOSRP works closely with the seafood industry and restoration partners and returned approximately seven million oysters to the water in 2018 with a 2019 goal of 12-15 million oysters being returned.

Some of the selections at the Shindig included:  

Alewife (Richmond): Seafood Gumbo (oysters and crab supplied by Reliant Seafood and J&W Seafood)
Aloha Snacks VB (Virginia Beach): Tuna Poke and Ruby Salts oysters topped with tuna tartar and lemon hot sauce (Tuna supplied by Sam Rust Seafood)
Dutch and Company (Richmond): Bratwurst from Autumn Olive Farms pork, apple butter mustard and kraut
Lemaire at the Jefferson Hotel (Richmond): Fried J&W Seafood oysters with sautéed seasonal greens
Longoven (Richmond): Grilled squid, white beans and seasonal mushroom ragout (squid supplied by Tuckahoe Seafood)

 Laura Duval, Sydney Bliss, and Lucas Berrigan process captured sparrow

CCB collaborates on study of winter ecology of ipswich sparrows

October 4, 2018

By Fletcher Smith and Sydney Bliss (M.Sc candidate at Dalhousie University)

Ipswich sparrows spend their lives on the wild edge where the Atlantic Ocean meets land. The entire population breeds on one small sandy island (the aptly named Sable Island) off the coast of Canada, and in migration and in winter they occupy sandy coastal habitat. These sparrows have evolved in this constantly changing environment, their plumage blending in perfectly with the open sand and tones of mid-winter vegetation. The dunes in which Ipswich spend their winters are susceptible to high-intensity nor’easters that strip seeds from plants and flatten or rearrange entire swaths of habitat. Heavy snow storms on the outer coast can bury most of the available seed crop. Severe cold temperatures on the northern end of their winter range likely cause some degree of facultative migration to warmer climes. But still these birds persist, and the degree to which they have adapted to this harsh environment is nothing short of amazing.

The dynamic nature of the dune/ocean interface makes for dramatic changes in annual occupancy. For instance, during CCB’s surveys of Metompkin Island in 2012 and 2016 we found over 20 birds/km of beach. To put that density into perspective, the seminal winter survey work conducted by Stobo and McLaren in 1971 found peak densities in the mid-Atlantic of 3 birds/km. This winter, with the dune habitat remaining unchanged to the human eye on Metompkin Island, we only recorded 1 bird/km. The annual variation in habitat used is likely summed up in one word: food. The birds likely have site fidelity between years if the seed base doesn’t change much, but our counts on Metompkin Island this past winter likely reflect a crash in dune grass seed production since our 2016 survey. The focus of our surveys during the winter of 2017-2018 was to determine the density and distribution of the sparrows across the mid-Atlantic from Delaware to North Carolina. We surveyed approximately 237 total kilometers of dune habitat throughout the field season from January through mid-March. We found a range of densities of the sparrows across the landscape, with the highest densities unsurprisingly recorded in wild natural dunes. We plan on expanding these surveys during the upcoming winter to better understand the distribution of sparrows across the winter range.

To better understand the processes that affect Ipswich Sparrow population size, researchers have begun a long-term study of the population using mark-resight techniques. To mark the sparrows, birds are affixed with unique combinations of colored leg bands. To date, 639 sparrows have been banded on Sable Island, Canada breeding grounds and on Delmarva Peninsula, USA wintering grounds. Sparrows will continue to be banded at these locations over the next several years and resighting surveys (i.e. finding the birds after banding) will occur in multiple locations along the eastern seaboard. The history and location of birds that are resighted can be used to make inferences about the demography of the marked population. For instance, researchers will be able to determine which life cycle stages (breeding, migration, or overwintering) incur the highest mortality in the population, estimate population size, and understand how various ecological factors affect population size.

The difficulties associated with following individual animals have long been a barrier to studying migrations. With the recent miniaturization of radio-transmitters, plus an extensive array of telemetry receivers in eastern North America (Motus Wildlife Tracking System), it is now possible to track small songbirds from start-to-finish during migrations. To better understand Ipswich sparrow migration, we affixed sparrows with radio transmitters on the Delmarva Peninsula in winter 2018. These small transmitters weigh 0.7 g and are attached to sparrows using a backpack-style harness. Using the Motus array, these sparrows were tracked thousands of kilometers from the Delmarva Peninsula to Sable Island during spring migration. Data from these transmitters will help us understand the migration of these birds, including what routes they take to Sable Island, where and for how long they stop to rest along the way, how long the journey takes, and constitutes the most dangerous legs of migration. Further, researchers can identify key areas that support migrating sparrows for management and conservation.

The 2017-2018 winter work was conducted with the help of many partners, land managers, and funding agencies, including the National Park Service, U.S. Fish and Wildlife Service, Dalhousie University, Acadia University, Delaware State Parks (Cape Henlopen, Delaware Seashore, and Fenwick Island), Delaware Department of Natural Resources Division of Fish & Wildlife, Virginia Department of Conservation and Recreation, The Nature Conservancy, Maryland Department of Natural Resources, Virginia Department of Game and Inland Fisheries, the North Carolina National Estuarine Research Reserve, and the North Carolina Wildlife Resources Commission. Ned Brinkley, Zak Poulton, and Courtney Check all contributed significant volunteer time and effort in support of this study.  

Eagle nest on the Patuxent Naval Air Station where great blue heron tarsus was recovered

A heron’s tale

October 4, 2018

By Bryan Watts, Center for Conservation Biology

On 1 May, 2018 while banding on the Patuxent Naval Air Station in Maryland, we found a great blue heron tarsal bone in one of the eagle nests.  The bone was clean but fresh and had an aluminum band.  After sending the band number to the Bird Banding Lab, we were informed that the heron had been banded on 5 July, 2001 as a nestling in Quebec, Canada, making it in its 18th year when it was killed.  Upon further correspondence with the Canadian Wildlife Service, it was determined that the bird was hatched in a colony on Steamboat Island in Wayagamack Lake by Louise Champoux.  The bird was included in a study monitoring contaminant exposure of great blue herons throughout the region around the St. Lawrence River.  This chance encounter helps to shed additional light on two lingering questions about great blue herons within the Chesapeake Bay including 1) what is the migratory status of great blue herons using the Chesapeake Bay and 2) what is the interaction between great blue herons and eagles?

Due to the latitudinal position of the Chesapeake Bay, the migratory status of many bird species is transitional such that populations north of the Chesapeake Bay are migratory and those south of the Bay are non-migratory.  To make things even more confusing, some of the species that we have assumed to be year-round residents because we see them here in the Bay all year actually go through a “changing of the guard” where our breeding birds migrate out for the winter only to be replaced by birds from northern breeding grounds.  Other species show a mixed strategy.  For example, through tracking our peregrines with satellite transmitters, we have determined that some of our birds migrate south and some remain resident through the year.  Although we know that great blue herons near the northern limit of their breeding range migrate south to open water for the winter, we have not known if or how these populations might use the Chesapeake Bay.  It appears from this recovery that at least some of these birds winter here in the Bay.  We know very little about the possible movement of Chesapeake Bay breeding birds out of the Bay to spend the winter.

The remarkable recovery of bald eagles within the Chesapeake Bay has had a clear downside for species that are included in eagle diets.  Increasingly, some of these prey species are other waterbirds such as ducks, gulls, cormorants, and some herons.  Over the past 20 years, we have suspected that the colonization of great blue heron breeding colonies has led to the splintering and movement of colonies, possibly due to predation on heron nestlings.  Adult great blue herons are large birds to take, even for bald eagles.  Despite their size, we have received periodic observations, photos, and videos from the public showing eagles hunting great blue herons.  Some of these hunts have been successful.  Finding this bird in the nest is further evidence that great blue herons are included in eagle diets during the breeding season.

 

Peregrine flying in the air

Female peregrines under pressure

October 3, 2018

By Bryan Watts, Center for Conservation Biology 

The 2018 breeding season was a rebuilding year for peregrine falcons in Virginia.  Of 39 slots within established territories where breeding adults could be identified in both 2017 and 2018, 23% of individuals had changed between years.  Although this annual turnover rate is one of the highest that we have recorded since initiating intensive identification efforts, the more interesting aspect is that males and females had markedly different rates.  Only 10.5% of males were lost compared to 35.0% of females.  This disparity between the sexes, although extreme in 2018, continues an ongoing trend and is opposite of the pattern of survival documented within the peregrine population breeding within the Midwest.

Peregrine falcons are dimorphic in size with females in many populations weighing 40% or more than males.  In addition to size differences, the genders have different roles during the breeding season with the female performing most of the brood rearing and the male responsible for much of the hunting.  Both sexes will defend the eyrie from intruders.

Although we have documented some mortality factors (car strikes, collisions, West Nile Virus, etc.) operating within the population, much of the annual losses remain a mystery and none suggest a gender bias.  We have rarely documented adult losses during the breeding season after egg-laying.  Most of the mortality we document is occurring before egg-laying and as with most peregrine populations, competition and fighting for prominent territories is intense.  It seems likely that a significant portion of the annual mortality may result from contest fights, but why this activity would exert greater pressure on females is unclear.

Laughing gull in flight over a marsh along the seaside of the Delmarva Peninsula

Losing ground to sea-level rise

September 27, 2018

By Bryan Watts, Center for Conservation Biology

 

They have names like Big Easter, Gull Marsh, and Egging Marsh – places where the early settlers of the Virginia Barrier Islands would go each spring to gather fresh eggs by the bushel baskets to carry over and sell to mainlanders.  Like a loud traveling party, the laughing gulls would return to their marshes each April with their raucous calls and showy flights.  There is nothing shy or demure about a laughing gull.  They nested in such dense colonies that it was easy work to collect hundreds of eggs in a morning.

The unique voice and constant calls of laughing gulls have been a familiar part of life on the Eastern Shore.  But over the past 15 years, many of the nesting marshes have gone silent.  Like neighborhoods called “Bear Creek” or “Eagle Point” in the heart of our cities, the early attributions have become empty place names – names that seem oddly out of sync in the context of today.

I first had the opportunity to survey these historic colonies from the air in the early 1990s.  On 27 May, 1993 Mitchell Byrd, Fuzzzo Shermer, and I flew for seven hours back and forth over the expansive marshes of the seaside mapping and counting colonies. It took a day and a half to complete the survey.  The larger colonies were beehives of activity that could be seen from miles away.  From above, the colonies nearly glowed with nests and birds contrasting against the deep green marsh grass.  On marsh islands the colonies were ringed like donuts where the birds built nests on rafts of wrack that had washed up along their perimeter.  On the larger marshes colonies were on high shelves and had a worn look as though they had been used for hundreds of years.  In a single round of surveys we tried to capture the series of colonies that had been known by generations of locals.  In the moment, with the drone of the engine and the chaos that comes along with surveying in the air, we had no sense of an approaching cliff.  Somehow things seemed as expected and the birds were going about their business as they had done for centuries.

We have had the privilege of conducting aerial surveys of the gull colonies approximately every five years since 1993 and have witnessed a rapid change since 2003.  Virtually all of the historic marsh colonies where residents once collected eggs no longer support nesting gulls.  From the air, I can still see the worn, high shelves in the marshes that are reminders of what once was.  They appear like ghost towns where time and the beehive of activity have moved on.  Between 1993 and 2018, the footprint of gull colonies on the lower marshes of the Eastern Shore coastal bay has declined from 326 hectares to only 15 hectares, a 95% decline.  It is staggering to recognize that these historic colonies have disappeared over such a short period of time.

Rising water and the increased frequency of inundation during high tides appear to have made these marshes unusable as breeding sites.  Equally concerning is the fact that the marshes have supported a community of breeding species.  Laughing gulls are visible occupants of the marsh patches and are easy to survey from the air.  Other, more secretive marsh species including clapper rails, black rails, seaside sparrows, saltmarsh sparrows, willets, and American oystercatchers are no doubt suffering from the same tides and may also be increasingly vacating these historic habitats.

VCU offers River Studies and Leadership Certificate program

September 6, 2018

 

Rivers...

Rivers play a central role in shaping landscapes and creating biologically diverse and unique ecosystems; they also form the foundation of cultures, economies, and communities.  Rivers connect us to nature, to our past, and to each other.

Leaders of the future with an understanding of the fundamentals of river sciences, river-related policy and management, and river-based recreation and education will be best equipped to make sustainable decisions about future uses, studies, and management of river systems around the world.

VCU is proud to be partnering with the River Management Society (RMS) and a cohort of eight other universities and colleges to offer the River Studies and Leadership Certificate program, awarded upon completion of river-focused coursework and a river-related professional project by RMS. VCU is the only school east of the Mississippi to offer a path to the certificate.

The certificate requires the completion of one course from each of four core areas -- GIS, River Safety, River Science, and River Policy, and then two additional courses in the student's area of specialization -- River Science, River-based Policy and Management, or River-based Recreation, Education, and Tourism. The student then completes a river capstone/professional experience. The certificate can be complete at either undergrad or graduate levels.

Is the River Certificate right for you? If you are passionate about rivers and could imagine a river or water resource related career like the answer is, yes!

To learn more, visit the RMS River Studies & Leadership web page or contact VCU coordinator, Dr. James R Vonesh, Assistant Director, Center for Environmental Studies.

In the wilderness of Idaho’s Lower Salmon River this summer, Virginia Commonwealth University student Abby Wright pushed herself to do things she’d never done before.

Along with her classmates in a new experiential course series at VCU, Wright — a sophomore biology major in the College of Humanities and Sciences — camped in backcountry with no contact to the outside world for a week, learned how to paddle down a river in an inflatable raft, and cooked for all 22 students, faculty and guides on the expedition.

“I made friends with people with similar interests to mine that I otherwise would have never met,” Wright said. “I feel incredibly inspired to push myself further now in my life outside of this class, trying to do more things that scare me every day.”

The series of classes, The River of No Return: The Lower Salmon River Experience, launched this summer as a collaboration of the VCU Outdoor Adventure Program, the Center for Environmental Studies in VCU Life Sciences, and the Department of Biology.

Female anhinga incubating on a nest in York County, Virginia

Anhingas march north

August 24, 2018

By Bryan Watts, Center for Conservation Biology

During the summer of 2018, CCB biologists conducted a three-day, cursory search for anhinga breeding locations that resulted in the location of six breeding sites, including fifteen active nests scattered across five jurisdictions in coastal Virginia.  Although these do not represent the first breeding records for the state, their number and distribution clearly demonstrate that the species is well-established as a breeding species in Virginia.  The nest site located in Charles City County is now the northernmost breeding area known throughout the species range.  Anhingas appear to be rapidly expanding their breeding range to the north.

Anhingas are birds of the Deep South.  They are known for silently slipping through the coffee-colored, tannic, shallow waters of the humid swamps that are such visible components of the southern landscape.  They dive and swim through the murky waters to catch fish.  Their low buoyancy (the result of wettable feathers and dense bones) helps in the pursuit of fish through submerged vegetation but also causes them to ride low in the water.  With only their head and neck extending above the surface they have been referred to by generations as “snakebirds.”

Since the discovery of a nesting site in the late 1800s on Orton Pond near Wilmington, North Carolina has been the northern range limit for breeding in the species.  During the 1930s, a wave of anhingas apparently moved north into North Carolina and nesting sites were documented within several counties.  In more recent decades, breeding has expanded north toward the NC/VA border.  Since 2010, sightings of anhingas in Virginia have increased dramatically.  Dave Youker documented single breeding attempts in 2009 and again in 2017.  Both of these attempts were on Harwoods Mill Reservoir in York County.

Given the significant number of sightings made during the breeding season, the likelihood that breeding is more widespread than the single known location would imply has been difficult to ignore.  During the summer of 2018, CCB biologists decided to explore several locations that support habitat suitable for breeding in an attempt to better understand current distribution.  Thirteen sites were surveyed including the Harwoods Mill Reservoir site.  Although no breeding was documented on Harwoods Mill in 2018, active nests were found within six of the remaining twelve sites.  All nests included either eggs or young.  Occupied sites were found within five jurisdictions scattered throughout southeastern Virginia, including Virginia Beach City and the counties of Isle of Wight, Prince George, York, and Charles City.

Southeastern Virginia supports a large number of sites with habitat that appears to be suitable for breeding anhingas.  The cursory survey conducted during 2018 suggests that the population is well established and much larger than previously appreciated.  Anhingas appear to be expanding their breeding range north on a rapid pace.

When swimmers, boaters or fisherman want to know the E.coli levels of the James River, they check the James River Association’s James River Watch website, which provides river condition data collected by volunteers on water temperature, turbidity, river height and bacteria.

This summer, a Virginia Commonwealth University student is playing a key role in providing that essential data to recreational users of the James River, stretching from Buchanan in the west to Norfolk in the east.

Rachael Moffatt, a senior environmental studies major, is serving as the James River Association’s water quality intern, a role in which she is coordinating the association’s 66 trained citizen-scientist volunteers — known as the “James RiverRats” — and supporting their work to collect samples and upload data on a weekly basis.

Hopewell and Prince George, Virginia (PRWEB)

Matt Balazik, PhD, is helping to restore the Atlantic sturgeon to the James River in Virginia. Balazik works for the Army Corps of Engineers and is a research assistant professor at the Virginia Commonwealth University Rice Rivers Center, just south of Hopewell, Virginia.

Balazik grew up in a house in Prince George County. “I could throw a baseball from my lawn into the James,” he said. “We knew of sturgeon, but it was more like folklore.” The sturgeon has disappeared from the James River. When Balazik went to Virginia Commonwealth University to earn a master’s degree in biology, he decided to write his thesis about the disappearing sturgeon. He continued that study for his doctoral dissertation.

Expedition Chesapeake

July 19, 2018

By Bryan Watts, Center for Conservation Biology 

The Chesapeake Bay is one of the largest estuaries in North America and one of the most productive aquatic ecosystems on the planet.  Its watershed covers portions of six states and is home to more than 18 million people.  The economic benefit flowing from the Bay to these six states is estimated to be 30 billion dollars annually.  In 2009, President Barack Obama signed an Executive Order designating the Bay as a national treasure and recognizing its importance to the entire country.  An intended outcome of this designation was to rally the resources needed to protect the unique constellation of species that rely on the Bay.  The Bay is subjected to an unrelenting assault from the people and industries that live and operate within its watershed.

Expedition Chesapeake is a multi-media project funded by the Whitaker Center for Science and the Arts that is designed to educate and inspire the residents of the watershed to become better stewards of the Bay.  It focuses on the interconnections found within the complex ecosystem and how activities within one portion of the Bay may have unintended consequences in others.  The anchor of the program will be a 44-minute, giant-screen documentary film that highlights the ecology and ongoing conservation research focused on six iconic species including the blue crab, oyster, striped bass, osprey, river otter and hellbender.  The film will be hosted by Emmy award winning TV personality, Jeff Corwin. 

CCB’s ongoing work with osprey on the upper James River will be featured in the documentary film.  Recently, a film crew from VIA Studios traveled down to the James along with Jeff Corwin to film nesting osprey and CCB biologists working on the river.  The film opening is scheduled for 19 March, 2019 in Harrisburg, Pennsylvania.  The film is intended to be distributed worldwide to reach museum audiences.

The 2018 breeding season was a roller coaster for endangered red-cockaded woodpeckers in Virginia.  Moving into the breeding season the state supported 17 potential breeding groups (clusters with at least a male and a female), including 14 within Piney Grove Preserve and 3 within the Great Dismal Swamp, NWR.  This is the largest breeding population supported by Virginia since the 1970s.  By 29 April the Piney Grove birds had already produced four clutches and by 4 May this rose to eight clutches, giving one of the earliest starts to the breeding season in recent memory.  By mid-May, 13 of the 14 Piney Grove groups had made breeding attempts.  However, after mid-May the tide of good nesting news had turned.  The one holdout pair had not laid a clutch and two of the existing clutches had failed.  Ultimately, three of the 13 pairs that made attempts would fail and the no show never showed.  In addition, the three pairs in the Great Dismal Swamp never laid clutches. 

Overall, the Virginia population fledged 22 woodpeckers resulting in a mediocre reproductive rate of 1.29 young per potential breeding group.  This compares to an average rate of 1.56 for the previous three years.  Only 23 (58%) of 40 eggs laid eventually hatched.  All 23 young hatched survived to banding age and all but one of these fledged from nest cavities.  The single young that did not fledge was grossly underweight at banding, weighing only 13.5 grams compared to 24 and 25.5 grams for its siblings.  Fledged birds included 12 females and 10 males.

Eagle productivity continues slide

July 18, 2018

By Bryan Watts, Center for Conservation Biology

The 2018 breeding season along the James River continued a trend that has been documented for the past 15 years.  The breeding population continues to increase while productivity continues to decline. The 2018 survey documented a modern record population of 289 breeding pairs along the James River compared to 274 in 2017 and 262 in 2016.  However, the number of young produced per territory sank to 1.09, a value not seen on the survey since 1982. The two opposing trends appear to continue the population’s path to stability.  

The shift in productivity can be seen in the details of breeding performance.  During the 2000 breeding season, only 15% of pairs that laid eggs failed to produce young compared to 34% in 2018.  Brood size has also become smaller over time. In 2000, 2-young broods represented 56% of all broods. In 2018, 2-young broods had fallen to 48% of all broods and 1-young broods had risen from 29% to 42%.  If this trend continues, 1-young broods will become the most common brood size. Three-young broods have declined from 15% to 10% and have become increasingly uncommon.

 

 Colony-wide metabolic demand peaks in July when the young are large but still growing

The fish factory

July 17, 2018

By Bryan Watts, Center for Conservation Biology

The brown pelican and double-crested cormorant nesting colony on South Point Marsh is like a shape shifter where fish are harvested, consumed and magically converted to bird flesh.  Located within an old marsh pasture on the south end of Smith Island, the colony is strategically positioned within the heart of the Bay and is one in a series of seabird colonies that stretch from Tangier Island north to Poplar Island.  But South Point stands high above all of the others.  In mid-July, when the metabolic engine revs up to its highest pitch, the colony is estimated to consume 4,900 kilograms (10,800 pounds) of forage fish per day, including staples like menhaden, bay anchovy and silversides.  During the course of the season, the colony is estimated to consume 950 metric tons of fish.  Many questions remain about the details of how the colony interacts with the various fisheries. 

The development of South Point Marsh into one of the great natural fish factories in the Chesapeake has happened over a short period of time.  In June of 1993, Gary Costanza was working black ducks on the Bay islands when Mitchell Byrd and Bryan Watts hitched a ride out to Fishbone Island to check on a tern colony and then up to South Point to survey the emerging colony that they had seen from the air.  The tide was ebbing fast, threatening to strand the boat for several hours on the expansive flats around Cheeseman Island as Gary put them off on the beach.  They had only minutes to scramble up over the low dunes and work through the colony.  Fifty-three pelican nests were scattered through the vegetation.  In a small cluster just on the crest of the dunes was a group of six cormorant nests with fresh eggs. 

As part of the state-wide colonial waterbird survey, CCB has had the opportunity to monitor the South Point colony over the years.  The most recent count conducted on 31 May, 2018 found 1,753 brown pelican nests and 4,606 double-crested cormorant nests.  After a dramatic increase through the 1990s and early 2000s, pelicans appear to have stabilized and come off of their peak of 1,857 pairs counted in 2013.  Cormorants continue to demonstrate explosive growth, nearly doubling since 2013 and now dominating the colony.  Collectively the breeding pairs represent the largest seabird colony within the mid-Atlantic region.

During the peak season, the South Point colony is a beehive of activity with fish-laden adults arriving from all directions.  The movement and sounds of adults and young rival that of Times Square during rush hour.  But the smells of addled eggs, dead young, rotting fish and guano are more like the rising stench of a landfill on a hot summer day.  The specific relationship between the colony and the fisheries it depends on is still poorly understood.  What is the size and shape of the net the colony casts on the Bay?  During the summer of 1999, Bryan Watts, Dana Bradshaw and Marian Watts made observations of the colony for more than a month.  Pelicans rose out of the colony on thermals nearly out of sight overhead and moved off great distances to forage.  Pelicans are now observed up the Potomac River as far as Colonial Beach during the summer, suggesting that the pelicans are harvesting fish from a large portion of the Bay.  But details on their foraging behavior and what impact the seabirds may be having on the various fisheries remain to be explored.

Urban herons hold their own

July 17, 2018

By Bryan Watts, Center for Conservation Biology

 

CCB biologists have monitored breeding herons within residential neighborhoods of tidewater Virginia (including the cities of Hampton, Newport News, Norfolk, Virginia Beach and Portsmouth) since the mid-1980s.  As part of the 2018 Virginia colonial waterbird survey (funded by the Virginia Department of Game & Inland Fisheries, the Virginia Coastal Zone Management Program and CCB), residential neighborhoods, parks and other urban areas were once again surveyed for breeding herons.  Despite the relentless efforts of homeowners to encourage the birds to move off of their properties, the birds continue to hold their own.

Although 11 species of herons, egrets and ibises nest in Virginia, only three including yellow-crowned night herons, great egrets and green herons are tolerant enough of humans to nest in urban settings.  Yellow-crowned night herons are the most widespread, nesting in neighborhoods that have stands of loblolly pines between 40 and 80 years old that are positioned around productive cordgrass marshes where they feed on crabs.  Their breeding locations appear like halos around these marshes. Great egrets nest in the crowns of loblolly pine stands that are greater than 100 years old. Great egrets feed on fish and because they are capable of flying up to 20 miles to feed, their colonies may form just about anywhere in tidewater.  Green herons typically nest in dense, low trees such as live oaks, willow oaks or crepe myrtles. Although they often nest in small colonies, isolated pairs also nest making them difficult to survey.

Over the past 30 years, urban herons have held their own in Virginia.  The population of yellow-crowned night herons has more than doubled over this time as pine trees in many neighborhoods have matured and now provide nesting substrates close to more marsh patches.  Although the number of great egret colonies has declined and colonies are associated with fewer estuaries, the overall number of pairs has declined by only 20%. The number of known green heron pairs has declined by more than 40%, but this species is particularly difficult to survey and monitor.

Driving through the dozens of neighborhoods during the spring of 2018 has been like traveling down memory lane with the ghosts of herons past perched on many corners.  Many of the nesting areas from the past are no longer being used. Since the 1980s, we have lost nine great egret colonies, some of which had been known for more than 50 years.  Many of these had occurred on vacant lots that are now developed. Others were nesting over houses leading to the removal of all nest trees. Unwanted, the birds have been bounced from neighborhood to neighborhood with the end result that colonies are now restricted to fewer estuaries.  For unknown reasons, yellow-crowned night herons prefer to build their nests over man-made structures including roofs, decks, driveways and cars. This behavior places the birds in direct conflict with homeowners, often resulting in owners removing trees or limbs to prevent nesting. Green herons fly under the radar and virtually all homeowners that host them never know they are present.  

Despite all of the opposition of homeowners to their nesting, herons have been resilient and have found ways of persisting.  Over the past 30 years, homeowners have come and gone. Many people who removed nest limbs or used other approaches to prevent nesting have died or moved away.  They have passed through neighborhoods like the summer rain. But the herons still return each spring, building their nests, raising their young and foraging in the rich estuaries that are their homes too.

 

Michael Rosenberg, Ph.D. announced as new director for Center for Biological Complexity

July 1, 2018

Dr. Robert M. Tombes, Vice Provost for Life Sciences and Research at Virginia Commonwealth University, recently announced that Dr. Michael Rosenberg will become the new director of the Center for Biological Complexity (CSBC). Dr. Rosenberg has held the position of associate professor in the School of Life Sciences at Arizona State University since 2008.  He received his Doctor of Philosophy in Ecology and Evolution from the State University of New York in Stony Brook in 2000, and his Bachelor of Arts in Biology, Geology and Anthropology from Northwestern University in 1994.

Rosenberg’s vision as director is that of biological data science: the use of computational and statistical approaches to collect, organize, analyze, and interpret life sciences data at all scales, from molecular and cellular levels through individuals, populations, and communities, thus encompassing scale-dependent subdisciplines such as bioinformatics, ecoinformatics, phyloinformatics, and biodiversity informatics. He seeks to recruit a set of independent tenure-track faculty with complementary expertise in computational methodologies who will collaborate and connect with diverse units and scholars across both campuses to tackle questions spanning all aspects of life sciences. He envisions his faculty offering core competency courses and/or workshops in bioinformatics for the VCU community at large.

“I am confident that Dr. Rosenberg has the experience and enthusiasm necessary to lead faculty and students, and to be an excellent collaborator,” stated Dr. Tombes.  “His use of modern bioinformatics tools to assess a full spectrum of problems from human disease to invertebrate evolution will benefit students and the entire research community.”

Examples of the diversity of his recent projects include comparative primate genomics, rattlesnake population genetics and the evolution of human diseases including HIV, tuberculosis and leprosy.

Dr. Rosenberg has published 47 peer-reviewed articles, is co-author of chapters in publications including Handbook of Meta-analysis in Ecology and Evolution and Handbook of Statistical Bioinformatics, as well a creator of meta-analysis and spatial statistical software. He will continue his position as associate editor for Molecular Biology and Evolution.

VCU receives funding for oyster restoration work

June 13, 2018

Virginia Commonwealth University’s Virginia Oyster Shell Recycling Program has partnered with Toadfish Outfitters of Charleston, South Carolina, to advance its efforts to replenish oyster populations in the Chesapeake Bay watershed. Toadfish Outfitters, a manufacturer of coastal lifestyle products, has designated the VOSRP as the sole recipient of proceeds from the sale of Toadfish products in Virginia. VOSRP will use the funding initially to acquire 20 million oyster larvae that will be planted on recycled oyster shell placed in Chesapeake Bay waterways. This will allow VCU to plant more than 2 million oysters in the watershed, and coincides with Chesapeake Bay Awareness Week.

“Oysters are the ultimate friend of the coast as they help to keep our waters clean,” said Casey Davidson, founder of Toadfish Outfitters. “Since day one, we’ve promised to give back a portion of every product sold toward oyster habitat restoration, so working with VCU was a natural fit.”

VOSRP, part of VCU’s Rice Rivers Center, is a collaborative, community-based oyster restoration program that works closely with the Virginia seafood industry. The VOSRP currently collects recycled oyster shells from more than 50 restaurants and 30 public drop-off locations statewide to use in the creation of sanctuary oyster reefs. The shells are seeded with juvenile oysters before they are planted. These efforts are direly needed because the Virginia oyster population is currently estimated to be at two percent of peak numbers.

Team Warbler visits The Steward School

Team Warbler visits The Steward School

May 23, 2018

Last month, members of Team Warbler were invited to The Steward School to talk about their adventures in Panama earlier this year. Elementary, and high school science students learned about what it was like to track and study the prothonotary warbler as they wintered in Central America, and were some of the first to learn about and view a new smart birdhouse that will be introduced to track the warblers’ movements and migration.

Team Warbler is a collaboration among VCU students from the Center for Environmental Studies, Biology Department, and College of Engineering, and are led by Life Sciences’ faculty members Dr. Cathy Viverette, Dr. Ed Crawford and Dr. Lesley Bulluck.  

“The Steward School students and faculty were blown away by the passion of the VCU students and professors.  The students that heard about the project have been putting their inspiration to action. The second grade students have been taking leadership roles at our school in helping save the oak seedlings on the playground to carefully following the birds nesting on campus since hearing from the VCU students. Our inspired Middle School students are going to benefit next year as they will have an opportunity to explore Kimages Creek and the habitat on the James River with the Rice Rivers Center students and faculty.”  -Cary Jamieson, Director of the Bryan Innovation Lab at The Steward School

A group of students left the bitter cold of Richmond behind to study abroad in Panama and follow the prothonotary warblers to their winter habitat. Dr. Catherine Viverette and Dr. Edward Crawford’s ENVS 515 Panama Avian Field Ecology class spent January 2 – 15 in mangroves and other tropical habitats tracking the small, yellow bird.  Beyond gathering data, one of the course requirements was to work with Panama Audubon Society and participate in community outreach in the host country.

VCU’s Team Warbler, accompanied by a graduate student from the Ohio State University, traveled to Panamá Viejo – the last remaining part of Old Panama City –  and partnered with the Sociedad Audubon de Panamá to hold a demonstration about bird banding and the importance of mangrove ecosystems to resident and neo-tropical migratory birds. They also educated local residents about migratory birds, local birds, and how banding allows scientists to study avian habits and health both locally and abroad.

VCU and University of Richmond introduce new speaker series

May 18, 2018

Last month, the VCU Center for Environmental Studies collaborated with the University of Richmond Department of Geography and the Environment, International Studies Program and Environmental Studies Program to host the first seminar in the newly-created Global Environment Speaker Series. 

Dr. Gary Machlis (pictured), professor of environmental sustainability at Clemson University, conducted a seminar based upon his new book, “The Future of Conservation in America: A Chart for Rough Water” to a classroom full of students and faculty from VCU and UR. Dr. Machlis served in the Obama Administration as a scientific advisor to the Director of the National Park Service, Jonathan Jarvis, who also serves as co-author of the book.

Immediately following the seminar, a student-led poster session was held in the Trani Center for Life Sciences. Students from both schools answered questions and showcased their works.  Presentation topics included the creation of a sustainability minor, biodiversity management on campus, solar power initiatives, and an analysis of the impact of riverfront access on student experience.

Dr. Rodney Dyer, director of VCU Center for Environmental Studies, and Dr. Peter Smallwood, associate professor of biology and coordinator of the Environmental Studies Program for the University of Richmond, were responsible for putting together this partnership.

Despite the storms, some eaglets made it through safely and are seen in a nest with their parent

Eagle struggle with late Nor’easters

April 6, 2018

By Bryan Watts, Center for Conservation Biology

For the Northeast coast, the winter of 2017-2018 went out with a dramatic train of powerful storms during an intense two-week period in early March.  The trio of storms in quick succession included Winter Storm Riley, Winter Storm Quinn, and Winter Storm Skylar.  The storms killed several people, knocked out power for millions, and frustrated travelers throughout the Washington D. C. to Boston corridor.  For eagles in the Chesapeake Bay, the timing could not have been much worse.  Early March is late in the incubation period and the window when most eaglets hatch in the region.  Eaglets are most vulnerable to cold and wet conditions within the first two weeks after hatching.  It would have been extremely difficult for adults to manage a clutch or young brood during torrential rains and 60 mph winds.

Following the Nor’easters, CCB biologists had the opportunity to fly and examine more than 300 nests along the James River.  The storms had a clear impact on many breeding pairs.  Nearly 25% of active nests (N = 280) had failed their first breeding attempts.  This early loss rate is a multiple of that observed during most years.  One of the most telling indicators of how pairs struggled with the storms was the observation of ten abandoned clutches.  Although abandoned eggs are observed every year, they are relatively rare.  CCB will fly a productivity flight in late April to record young in the nest and see how many of the failed pairs will recycle and make a second breeding attempt. 

CCB has examined the impact of high winds on eagle nests in the past following Hurricanes Isabel and Irene.  In 2007, Bryan Watts and Mitchell Byrd published a paper titled, “Impact of Hurricane Isabel on bald eagle nests and reproductive performance in the lower Chesapeake Bay.”  The paper documented that 40% of nests were damaged or lost during Hurricane Isabel and that pairs losing nests were both less likely to breed and less productive the following spring.  Productivity for these pairs improved two years following the storm and was back to normal levels during the third breeding season.  A similar rate of nest damage was documented following Hurricane Irene.

Despite the sustained high winds, the impact of the Nor’easters on the eagles was different than the hurricanes examined.  Only four nests that appeared to have been active were damaged or lost compared to 40% during the two hurricanes.  The impact of the storms was on the loss of eggs or young and this is likely the consequence of timing.  Even though many nests appear to have been disrupted by the storms, many broods of small young made it through the storm intact.

Georgia coast critical for migrating red knots

April 5, 2018

By Bryan Watts and Fletcher Smith, Center for Conservation Biology

The coast of Georgia plays a significant role as a migratory staging area for the rufa population of red knots.  The population experienced a precipitous decline over the past 40 years leading to its eventual listing as “threatened” under the U.S. Endangered Species Act.  Although researchers have worked for decades with the portion of the population that stages along the mid-Atlantic coast, much less has been known about birds using coastal Georgia.  During the fall of 2017, CCB, along with project partners the U.S. Fish and Wildlife Service, U.S. Geological Survey, Georgia Department of Natural Resources Non-game section, and Manomet, Inc., released a report entitled “Investigating Red Knot Migration Ecology along the Georgia Coast.”  The report summarizes a multi-year effort to examine knots using Georgia primarily during spring migration. 

Fletcher Smith of CCB led fieldwork that focused on the chain of barrier islands within Camden, Glynn, McIntosh, Liberty, Bryan, and Chatham Counties.  Seven barrier islands were selected for intensive resighting efforts during the 2016 season: Gould’s Inlet, Pelican Spit, Rainbow Beach (on Little St Simons Island), Sapelo/Cabretta/S. Blackbeard Island, Ogeechee/Raccoon Key Bar, Little Tybee/Beach Hammock, and Tybee Island/Bar. The CCB crew and volunteers surveyed knots within these specific sites and scanned birds for coded leg flags.  During the spring of 2016 alone more than 43,000 knot encounters were recorded and more than 10,000 of these were scanned for flags resulting in the identification of 1,255 flagged birds.  A total of 158 marked to unmarked ratios were recorded during the season, with an average of 3.8% of birds encountered throughout the spring being marked.  Jim Lyons of USGS evaluated encounter histories within a Jolly-Seber modeling framework to estimate the population size using the Georgia coast and the duration of stopover.

The two most significant findings of the study include the number of birds using the Georgia coast during the spring and how long these birds are staging.  During the spring of 2016, just under 12,000 total knots were believed to have used Georgia as a stopover or staging area.  The current estimate of the rufa population is 42,000, suggesting that more than 25% of the population was present in Georgia during the spring.  A model-based estimate of stopover duration during the 2013 spring season was 3.4 weeks, suggesting that a portion of the birds are using the Georgia coast for an extended period and likely flying from Georgia directly to the breeding grounds in the Arctic.  These results follow a recent paper published in the Journal of Wildlife Management and led by Jim Lyons that evaluates the use of the Georgia coast by the rufa population during fall migration and estimates that more than 23,000 birds staged there in 2011.

Migratory staging sites play a critical role in the life cycle of many shorebird species and maintaining conditions that allow for rest and refueling is an important conservation priority.  The Georgia coast appears to be a key node within the broader network of conservation sites for the rufa population.

Funding and support for the project was provided by the U.S. Fish and Wildlife Service, Gulf Power and Southern Company’s Power of Flight Program through National Fish and Wildlife Foundation, the U.S. Geological Survey, Manomet, Inc., The University of Georgia’s Center for Research and Education at Wormsloe, the National Park Service, The Nature Conservancy, the staff of St. Catherine’s Island, Little St. Simons Island, Ossabaw Island, and Cumberland Island, the staff of Bandedbirds.org, and The Center for Conservation Biology. This study would not have been possible without the significant effort of all of the researchers tagging Red Knots along the flyway.

A good year for woodpeckers

April 5, 2018

By Bryan Watts, Center for Conservation Biology

2017 was a good year for red-cockaded woodpeckers in Virginia.  The combined spring, breeding, and fall surveys within The Nature Conservancy’s Piney Grove Preserve (PGP) and the U.S. Fish and Wildlife Service’s Great Dismal Swamp National Wildlife Refuge (GDSNWR) identified 96 individuals during the calendar year.  This is the largest number of woodpeckers known to occur in the state since the early 1980s and includes 61 resident birds, 27 birds fledged during the 2017 breeding season, and 8 birds that were moved into the state from Carolina Sandhills National Wildlife Refuge.  Ongoing management efforts by The Nature Conservancy, The U.S. Fish and Wildlife Service, the Virginia Department of Game & Inland Fisheries, and The Center for Conservation Biology are increasingly pushing the population toward recovery goals.

The 2017 breeding season included 15 potential breeding groups (13 in PGP; 2 in GDSNWR) that fledged 27 young (18 females; 9 males).  Fourteen of the 15 breeding groups actually made breeding attempts and 12 actually fledged young.  Of 45 eggs that were followed through the breeding season, 24 (53.3%) hatched and 23 (51.1%) fledged.  Seventeen (73.9%) of these fledglings were still present within the population during the winter count.  Based on the results of the winter census we are hopeful that the Virginia population will support an increase in the number of potential breeding groups for the 2018 breeding season. 

 

Nestling eagle fitted with satellite transmitter

Networking eagles

April 3, 2018

By Bryan Watts, Center for Conservation Biology

Nonbreeding bald eagles are highly social and form communal roosts around profitable foraging sites.  We have known for decades that eagles frequently switch back and forth between different communal roosts but have lacked the movement information to evaluate the basic structure of roost networks.  The relatively recent development of GPS transmitters and other tracking devices that have enabled the remote tracking of large samples of eagles has opened a new era of data collection with the potential to view individual roosts within a network context.  Bryan Watts from CCB and Rodney Dyer from the Center of Environmental Studies at VCU have used movement data from 56 eagles outfitted with satellite transmitters to evaluate the roost network within the upper Chesapeake Bay.  The study entitled “Structure and resilience of bald eagle roost networks” was recently published in the Wildlife Society Bulletin. 

The researchers used 14,464 midnight locations to determine the use of communal roosts and 2,634 movements between roosts on successive nights to evaluate the pattern of connectivity between roosts.  Among other findings, the study revealed that the structure of the 212-roost network was consistent with the well-known scale-free network.  The scale-free network is a common form where the majority of nodes (roosts in this case) have few connections to others and very few nodes (referred to as hubs) have many connections.  Hub roosts serve as bridges between large numbers of other roosts, have the shortest travel times to other roosts and the greatest overall influence on network functioning.  More than 50% of roosts were connected to fewer than 10% of other roosts and only seven had connections to more than 50% of the roost network.  Incredibly, the Sod Run roost on Aberdeen Proving Ground was connected to 204 (96.7%) of the possible 211 other roosts.  This roost was Grand Central Station and the central hub of the entire network.

Bald eagle communal roosts are protected by federal law.  Understanding the structure of roost networks helps us to make better decisions about roost protection and management.  One feature of the study was to evaluate the effect of losing individual roosts on the functioning of the overall network.  Not surprisingly, the effect of roost removal on overall network function was directly proportional to the connectivity of the roost being removed.  Removal of the majority (>90%) of individual roosts would have relatively little impact on the network.  The study identified 18 highly connected roosts that are important to network function and that should be the focus of any management strategy.

Results from the network study provide insight into the basic ecological question of why eagles gather together.  One of the proposed advantages of sociality in nonbreeding eagles is food finding through following behavior from communal roosts.  Some eagles have been shown to gain an advantage from associating with roosts by increasing their likelihood of finding or stealing food.  This benefit is believed to be particularly great for young, inexperienced eagles that have yet to master hunting skills and often resort to stealing or scavenging to meet their energy needs.  Hub roosts may represent concentrated information resources that may be visited periodically by eagles from throughout the network to stay in the information loop.

 

 

Whimbrels with tremendous fat reserves from feeding on blueberries take off from the Acadian Peninsula headed out over the Atlantic

Flying to Mecca

April 2, 2018

By Bryan Watts, Center for Conservation Biology

Fletcher Smith and I had been working birds on the Acadian Peninsula for ten days.  We had been flying surveys of blueberry fields and heath barrens, driving survey transects, observing the work of the berry wardens, and watching the birds coming into fields at dawn to get a sense of how foraging flocks worked the landscape.  We were spending evenings following birds out of fields to locate communal roosts.  Most of the birds on Miscou Island and the northern portion of the peninsula were concentrated in Petit-Shippagan, a simple crossroads with a dozen houses, many of which have private blueberry fields in back.  More than 300 birds had been feeding in one field for the past four days to the chagrin of the farmer who made hourly drives around the field firing a shotgun to protect his only cash crop from the birds.  The birds had come from western breeding areas to their late summer staging grounds in the Canadian Maritimes.  They would spend three gluttonous weeks here eating, resting, and putting on fat - their last tastes of summer before moving on for the winter. 

We sat in stake-out position along the southern corner of the field watching for birds to fly out for the evening to roost.  The birds were unusually skittish, rising and resettling every few minutes.  Finally, 32 birds rose with purpose and flew southeast, a sector with no known roosts.  I started the car and hurried after them hoping to maintain contact and get a bearing that we could follow up on in the coming days.  To my surprise, the birds were following the two-lane road to the small town of Lameque and I drove directly under the flock making just under 48 kph for11 kilometers.  As the flock flew over the Lameque fire department, I turned off, parked, and ran out to the end of the commercial dock to set up a scope and watch the birds emerge out over the water.  They were flying toward a treeless island in the back corner of the bay and I was excited that they were about to reveal their secret roost.  But the birds overflew the island, and as they gained air over the far tree line I realized that they were not going to roost.  They were leaving.

I walked back to the car realizing that it was too late to get back to the berry field to pick up another flock and sat in the parking lot to watch the sun lay down on the water toward the Gaspe Peninsula.  I had unknowingly given the flock a send off from Berryville.  They were heading out over the open Atlantic into the unknown.  It would be impossible for the flock to know what storms might be brewing in Hurricane Alley.  They would fly nonstop for six days and cover more than 6,000 kilometers.  You have to respect any animal with the bravado to fly out over the open ocean with no safety net.  I knew that the next ground they would touch would be in Brazil and the next meal they would eat would not be blueberries, but tropical fiddler crabs.  Bem-vindo ao Brasil!  They were going to the land of plenty.

The gravitational pull of the delta reaches throughout the entire hemisphere, gathering birds of many stripes.  They come from all corners.  To date, we have tracked 26 whimbrels from the Mackenzie River and Hudson Bay Lowland breeding areas to their winter range and >90% have wintered within the Amazon Delta.  Some of these birds fly directly to the delta while others make landfall in Venezuela.  Early in the tracking project we thought that the latter birds would overwinter in these locations, but during the late fall they would slowly skip east along the shoreline to join the others in Mecca and pay their respects to the delta. 

 

We all know of the vast Amazon rainforest (lungs of the word; greatest assemblage of species on the planet) and the Amazon River (largest drainage basin in the world; holds more than one-fifth of the world’s fresh water).  Much less is known about the critical importance of the Amazon Delta.  In addition to carrying a tremendous supply of fresh water, the river produces the largest sediment discharge of any river.  The enormous plume of sediment and nutrients that is spewed from the mouth of the river is pushed hundreds of kilometers out into the Atlantic.  The plume collides with the North Brazilian Current and is directed west, fertilizing more than 1,500 kilometers of the South American coastline.  The nutrients spread over this vast area create a productivity bonanza.  It is this natural gusher of productivity that attracts the whimbrels each winter along with throngs of other waterbirds.

The power of the Amazon is drawn from its wildness - the unfettered flow of water, the forested drainage basin, the sheer power to wield its way on the entire coast.  Plans for infrastructure transformation within the Amazon basin threaten this wildness, including a cross-national highway system, river and sea-ports, a sequence of dams for transportation river-ways, and hydro-electric plants.  Will we see this great river be made impotent by dams like the whimpering Mississippi or be smothered by agriculture and contaminants like the Mekong?  Will we consider this frontier something to be conquered and exploited or something to be preserved and protected?  The river is still wild and its future is in our hands.  We should all ask ourselves if we have learned anything from how we have treated many of the world’s iconic rivers.  Do their fisheries still thrive and do they still serve the many consumers that once depended on them? 

Watching the flock leaving the Acadian Peninsula, it is hard not to be concerned about the perils they may face out over the open Atlantic.  Perils like storms and winds that we have no control over and that have shaped the evolution of their migration pathways.  Harder still is wondering what they will find when they arrive after their long flights in the coming decades.  We can hope that they will still find their land of plenty.

A still of an oyster harvester in the short documentary film “An Oyster’s-Eye View of the Virginia Oyster Shell Recycling Program

VCU Rice Rivers Center documentary wins prize at RVA Environmental Film Festival

February 8, 2018

By Leah Small, University Public Affairs
 

A short documentary by a VCU Life Sciences faculty member is the winning entry for local environmental subjects at the annual RVA Environmental Film Festival.

“An Oyster’s-Eye View of the Virginia Oyster Shell Recycling Program,” by Ronaldo Lopez, showcases the work of VOSRP, an initiative of the VCU Rice Rivers Center. The recycling program, headed by Todd Janeski, aims to restore oyster populations in the Chesapeake Bay watershed through the creation of sanctuary oyster reefs. VOSRP recycles waste oyster shells from partner restaurants to use as the substrate of these reefs.

Lopez, a faculty research associate at the Rice Rivers Center, used inventive camera work to communicate the work of VOSRP through the “eyes” of an oyster. A combination of wide shots and shots from the perspective of an oyster being harvested, plated, eaten and finally recycled, tell the life story of the bivalve.

By Leah Small, University Public Affairs

Many adolescents who have spent their lives in Richmond’s high-poverty areas are not able to explore the natural wonders this river city and surrounding areas have to offer. Lack of transportation, money and time are the main barriers of access to the natural world for low-income families.

VCU Rice Rivers Center aims to get more kids outside despite the obstacles through a collaboration with the Richmond-based nonprofit Blue Sky Fund.

Rice Rivers Center is one of multiple sites throughout the state used by Blue Sky Fund for weekend, school-day and after-school programs.

The center is a nearly 500-acre environmental research facility located in Charles City County along the James River, which makes it an invaluable resource for Blue Sky Fund youth programs. Blue Sky Fund takes Richmond Public Schools students to the center to receive real-world environmental science instruction and to experience activities such as camping, volunteering and canoeing on the river.

Group shot at Kosi Bay, South African, for the 2018 VCU study abroad class South African Summits to Sea

VCU South African Summits to Sea explores connections between freshwater biodiversity and society

January 23, 2018

Students in Dr. James Vonesh’s VCU study abroad class rang in the 2018 new year hiking to the source of the Tugela River below the Mont-aux-Sources high in the Drakensberg mountains of KwaZulu-Natal Province, South Africa. Reaching the Tugela source involved a strenuous hike and scaling a series of chain ladders to gain the top of the Drakensburg escarpment, but rewarded the class with outstanding views of the Tugela Falls which plunge nearly a kilometer over the Drakensburg Amphitheater escarpment and are one of the highest falls in the world.

The course – South African Summits to Sea: Watershed-scale Perspective on the Human and Natural History of KawZulu-Natal – focused on major river watersheds of the KwaZulu-Natal Province, specifically the Tugela and Pongola rivers.  Students explored the relationships between freshwater resources, biodiversity, and South African history and modern society as they followed gravity and the flow of water from the peaks of the Drakensberg Mountains to the marine protected areas of Kosi Bay. 

Field work, hiking, rafting and kayaking, with primary accommodations being tents, were part of student life as they began the journey in Johannesburg and made their way to the rivers.

The class partnered with African Insights Academy, a company that tailors programs for a unique education experience showcasing the diversity of ecosystems in South Africa.  The video below, produced by African Insights, highlights some of the students’ hike through the Drakensberg.

A pair of breeding eagles on breeding territory in Norfolk, Virginia

Gender divide in bald eagles

January 17, 2018

By Bryan Watts, Center for Conservation Biology

Unlike many familiar bird species, male and female bald eagles have identical plumage making them difficult to distinguish in the field, but they are not the same.  In the hand, females have distinctly larger feet and this character alone may be used successfully to separate the sexes.  Females are 30% heavier than males with a nearly 20% longer tarsus (lower leg bone).  Females also have longer wings and deeper bills than males.  When standing together, males and females of a mated pair are nearly always easy to distinguish.  However, geographic variation confounds separation on the basis of size alone when birds are alone or in mixed groups.

Beyond the measurements, males and females cut a different line across the sky.  Differences in weight result in subtle differences in the proportions of body to wings that with experience may be observed in flight.  It is like watching a quarter horse and a draft horse running across a field.  The differences in weight and build influence movement.  Female eagles express a more labored flight style.  Watch closely for these differences the next time you see a group of eagles in active flight.

During the breeding season there is a division of labor between the sexes that extends to incubation.  Females have a much larger brood patch, making them more suited to incubate clutches and brood small young, particularly during poor weather.  Females cover more of the incubation duties and incubate when they choose.  In effect, males fill in for the female when she wants to be relieved.  This dynamic is readily apparent when observing shift changes.  If the male returns to the nest to relieve the female without being called she may or may not accommodate the male regardless of how vigorously he attempts to replace her.  By comparison, if the female returns to the nest she will supplant the male regardless of how long he has been incubating. 

Although patterns may vary between pairs, for nests within the Chesapeake Bay, females observed on video accounted for 73% of the incubation duties on average.  The gender disparity was driven primarily by the female taking the night shift.  In all cases recorded (>150), the female covered incubation for the night.  Night shifts averaged 13 hours and 20 minutes, or more than half of the 24-hour cycle.  During the daylight hours between 6:00 AM and 4:00 PM, the pair split incubation duties relatively evenly. 

One of the more interesting aspects of the team effort is that the length of the night shift imposes a basic structure on the daily pattern of incubation.  The most predictable shift change occurs around dawn after the long shift performed by the female.  The male is punctual in relieving the female and often performs his longest shift of the day.  Covering the early morning shift allows the female to leave the nest and take care of self-maintenance activities such as feeding and preening.  When she returns, the female typically performs her longest shift of the daylight sequence.  The afternoon is the most dynamic period within the 24-hour cycle, with multiple exchanges and short shifts.  The day typically concludes with the male performing his shortest shift of the day just before the female settles in for the long night shift.

A male Virginia peregrine

Virginia peregrines have mixed year in 2017

January 16, 2018

By Bryan Watts, Center for Conservation Biology

Virginia supported a known population of 29 pairs of peregrine falcons during the 2017 breeding season (download 2017 report).  Two new breeding sites were documented but three long-standing territories were unoccupied.  The population had a relatively high hatching rate (81%, 56 of 69 eggs hatched) but some losses both before banding (16.1%, 9 of 56 young lost) and after fledging (3 young known to be lost post-fledging).  Of 21 clutches that could be followed completely from laying to fledging, 41 of 53 (77.4%) eggs hatched and 35 of 41 (85.4%) young survived to banding age.  The reproductive rate (1.62 young/occupied territory) was considerably lower than in recent years. 

Efforts continued in 2017 to identify breeding adults via field-readable bands to better understand dispersal and demography throughout the mid-Atlantic region.  The banding status of 47 (81%) of the 58 adult peregrines known within the breeding population was determined.  Ten (21%) of the 47 birds were unbanded.  The alpha-numerics were read for 29 adults and of these the USGS bands have been recorded for 26.  Of the banded birds where state of origin could be determined, 22 were from VA, 5 from NJ, and 3 from MD.  Birds ranged in age from 2 to 17 years old. 

In addition to adults breeding in Virginia, bands for 12 additional falcons were read and reported over the past year.  Seven of these birds (all females) originated in Virginia and were found breeding in other states, including 3 birds in Pennsylvania and 4 birds in New Jersey.  A second-year female was photographed multiple times on Chincoteague National Wildlife Refuge.  A hatch-year male from Richmond was photographed in Lyndhurst, NJ and a hatch-year female that had been hacked in Shenandoah National Park was photographed near Silver Lake in Rockingham County, VA.  A 5-year-old female was identified in Westchester, NY during the early breeding season and may have been on a territory.

The translocation of falcons from the coast to the mountains in an effort to re-establish the historic mountain range continued in 2017.  Ten young falcons (including five females and five males) were moved to Shenandoah National Park and hacked.  All birds were from bridges that have experienced poor fledging success except two birds that were found on the ground under the Possum Point stack around the time of fledging.  All birds fledged and dispersed successfully. 

The Virginia population continues to benefit from a tremendous community of dedicated agencies, corporations, and individuals including the Virginia Department of Game & Inland Fisheries, the Virginia Department of Transportation, the U.S. Fish and Wildlife Service, the National Park Service, the U.S. Coast Guard, the U.S. Department of Defense, Dominion, and The Nature Conservancy.

Young male red-cockaded woodpecker ready for transport for Great Dismal Swamp National Wildlife Refuge

Moving woodpeckers 3

January 16, 2018

By Bryan Watts, Center for Conservation Biology

“She’s a peeker,” I whispered over the radio to let Bart Paxton know that the bird was looking out of the cavity entrance.  Bart was hidden in camouflage near the base of the cavity tree within The Nature Conservancy’s Piney Grove Preserve (PGP).  We had arrived on site around 4:30pm to measure the cavity height, position the net pole near the roost tree and set up for the capture.  The bird flew to the tree from the north at 5:05, did some maintenance work on resin wells, and entered the cavity at 5:13 with no inkling of the capture plan. 

Bobby Clontz and I were set back in the woods like a sniper with a spotting scope to monitor her activity and to direct Bart when the coast was clear.  The bird popped back up to the entrance every few seconds to peer out and scan the surroundings, but eventually settled down for the night.  Bart eased into position and slowly raised the net pole to 38 feet and placed the net over the cavity.  In seconds the bird shot out calling into the net, fluttered down into the bag and was lowered to the ground.  A collective sigh of relief after we confirmed the ID and had the bird safely in the transport box.

Less than a mile away, Fletcher Smith, Kevin Rose, Jen Wright, and Audrey Boraski were in another breeding site attempting to extract a young male from its roost cavity.  By 6:20 they had the bird secured and by 6:40 we were on the road to the Great Dismal Swamp National Wildlife Refuge (GDSNWR).  We would walk through the woods, climb the trees, place birds in artificial cavities, screen the birds in, and clear the gear out of the site by headlamp.  Before dawn we would quietly walk back into the site, wait for signs of the birds stirring, pull the screens and release the birds into their new habitat.

The successful movement of these two birds represents the first translocation of red-cockaded woodpeckers from PGP (itself a small recovering population) and the last birds to be moved to the GDSNWR in 2017.  Three weeks earlier, with a much larger group of biologists, we successfully moved eight woodpeckers (including four males and four females) from the Carolina Sandhills National Wildlife Refuge to the GDSWNR.

2017 is the third consecutive year that woodpeckers have been moved into the GDSNWR in an effort to establish a second breeding site in Virginia.  Eight birds were moved in 2015 and ten birds were moved in 2016.  In all, 28 woodpeckers have been meticulously monitored, captured, transported, and ultimately released from artificial cavities within the refuge.  All birds have been released successfully.

 

Update on the status of GDSNWR woodpeckers

CCB biologists and refuge staff began a survey of woodpeckers on the GDSNWR in early December 2017.  The survey systematically roosted all recruitment clusters and artificial cavity trees over a period of several days and identified all birds using the sites.  2017 was a good retention year with six of the ten birds that had been moved earlier in the fall found roosting.  A very good sign was that both of the females produced within the GDSNWR during the breeding season were still present.  The 11 birds identified included four males and seven females, setting up the possibility of four breeding pairs for the spring.  We will conduct another headcount in April to assess who is still standing as the birds move into the breeding season.

 

It takes a village

The successful movement of woodpeckers is an enterprise with a lot of moving parts that requires a large effort.  The work begins in the early fall when target and backup birds are identified and roosted to determine target trees for capture.  In the run up to movement night, birds and trees are reconfirmed.  Artificial cavity trees within GDSNWR must be cleared and screened to prepare them for receiving birds.  Over the past three years the effort has included the work of dozens of biologists and volunteers associated with a large consortium of agencies and organizations including the Great Dismal Swamp NWR, Carolina Sandhills NWR, SD Hamilton Noxubee NWR, Okefenokee NWR, two USFWS ecological services offices, Jay Carter and Associates Inc., Virginia Department of Game & Inland Fisheries, The Nature Conservancy, and The Center for Conservation Biology.  The effort has been lead by the national red-cockaded woodpecker recovery coordinator, Will McDearman.

Using the sword of Damocles to decapitate The Migratory Bird Treaty Act

January 3, 2018

By Bryan Watts, Center for Conservation Biology

On 22 December as the nation was gearing down for the festive Christmas holiday, the Department of Interior quietly released a memo redefining the terms of how the Migratory Bird Treaty Act (MBTA) will be enforced.  The document, written by the agency’s new Principal Deputy Solicitor, Daniel Jorjani, will have far-reaching impacts on bird conservation throughout the United States and represents the culmination of a decades-long fight by lobbyists to undermine the Act.  The action effectively removes (by interpretation) a key prohibition and constrains the U.S. Fish and Wildlife Service (USFWS) from pursuing the original intent of the Act.   

The MBTA (and its predecessors) has been the legal cornerstone of bird protection in the United States for more than 100 years.  The Act represents the legal first-line-of-defense for more than 1,000 species and its mere existence and long history is a reflection of how our society has valued bird populations.   By drawing a line in the sand defining acceptable conduct, the Act has educated generations of conservation-minded citizens and set a standard for corporate behavior.  The memo released on 22 December shifts the line and by doing so represents a sea-change in the value that our society places on bird populations.

Wildlife laws are often vague and include terms that are open to interpretation.  From a practical standpoint, implementation of these laws requires that regulatory agencies formulate working definitions that may be used to clarify prohibited activities to telegraph intended prosecutorial boundaries.  Changing the definitions effectively changes which behaviors will be prosecuted under the law.  The MBTA clearly states a prohibition on “killing” protected birds.  Over the past several decades, the U.S. Fish and Wildlife Service has recognized killing to include “intended take” (e.g. shooting and capture) and “incidental take” (unintended killing) as prohibited behaviors under the Act.

In practice, the U.S. Fish and Wildlife Service has long recognized two forms of “incidental take,” including accidental killing where the mortality could not have been reasonably anticipated or avoided and unintended killings where the mortality could have been reasonably anticipated and prevented.  No one wants to prosecute every homeowner who has had a bird fly into a window or every driver who has hit a bird flying across the road, and no prosecutions of this type have been brought forth.  However, situations where a party knowingly places large numbers of birds at risk of being killed should be avoided (see example below following the main story), and it is in the public’s interest to have legal deterrents to these activities.  In the past, the USFWS has used the MBTA to work toward resolving these types of incidental takes to protect bird populations.  The 22 December memorandum eliminates the legal avenue to find a reasonable solution.

The MBTA was passed during a time when very large numbers of birds were being taken for commercial enterprises for collections or to prevent perceived impacts to game or farm animals.  However, the intent of the MBTA was not merely to restrict recreational collecting and other activities, but instead to preserve bird populations in perpetuity.  In his long and winding memorandum, Solicitor Jorjani abandons the original intent and redefines “killing” as only including acts with the “intent” to kill birds.  Birds that are killed during activities where the primary intent is other than to specifically kill birds are no longer subject to the Act. 

In making this change, Jorjani invoked the words of Justice Thurgood Marshall, “the value of the sword of Damocles is that it hangs – not that it drops.”  Marshall used the anecdote to refer to the chilling effects that power or the overbroad interpretation of laws may have on the liberties of those subject to the law.  Without question, balance is the key to effective implementation of wildlife laws.  However, bird populations belong to the public, and reasoned measures should be taken to protect our shared heritage.  In making this change, Jorjani has in effect hung the sword over the heads of many bird populations and left them without a legal advocate.

I have worked in the bird conservation business long enough to have seen many, many examples of how the MBTA has been used reasonably and effectively to avoid unnecessary impacts to bird populations.  In the majority of cases, birds could be protected with minimal impacts to business.  One example from the past comes to mind.

In June of 1994, while surveying for piping plovers on the north end of Wallops Island in Virginia, I could see an unusually white wrack line in the distance as the tide ebbed out.  The mystery was not resolved until I actually reached the line, examined the white objects, and realized that they were the bleached keels of red-throated loons.  The line of keels stretched more than a mile to the north and represented 10,000+ loons.  Sometime during the winter there had been a significant kill and the keels piled up by the surf were what remained.  Later investigation revealed that the loons were bycatch from the nearshore gill netters, the same group that had been responsible for scores of sea turtles and bottlenose dolphins that had been washing up on the islands for years.  The netters were not charged, but with full consideration of the implications of MBTA, they were convinced to move farther off shore beyond the normal foraging area of the loons.

Under the MBTA that Jorjani envisions, the loons killed by gill netters would not be subject to any legal violation.  After all, the gill netters were there to catch fish, not birds. Yet since they had to remove the loons from nets, they had to be aware of the hazard they were creating for a federally protected species.  But here killing the loons was a mere nuisance.  Removing any legal liability from parties who recklessly kill large numbers of protected birds, despite being able to avoid doing so, is a clear perversion of the original intent of MBTA and serves no one but those in special interest groups.

This paper is a landmark study in biogeography that compiles and analyzes the distribution map of all reptiles in the world. Reptiles are the last group of terrestrial vertebrates (after mammals, birds, and amphibians) that are studied that way and complete the large-scale biogeographic analysis of tetrapods. This study informs us which species-rich regions need protection to maximize conservation efforts. Dr. Uetz kept track of reptile taxonomy in this study.

As a side project to the previous paper, this study identifies about 1000 lizard species which are only known from their type locality, i.e. literally only from one locality at all. Many of these species have never been seen again after they were discovered, so they represent the most threatened of all species.

 

 

Dr. Ed Crawford leads a workshop at VCU Rice Rivers Center for ENVS 201

ENVS 201 2017 Rice Rivers Center Field Day

December 6, 2017

Each year, Dr. Vickie Connor’s Introduction to Earth System Science class (ENVS 201) visits the VCU Rice Rivers Center to experience a few typical field research activities at the center. Dr. Ed Crawford, deputy director of Rice Rivers Center, and teaching assistants Alissa Nicholsson, Hannah Coovert, Rebecca Dahlberg, and Lindsay Schneider, joined Dr. Connors and 35 students on an overcast and windy Saturday in November.  

The day began with an orientation presentation by Dr. Crawford, where he shared the history of the ongoing evolution of the center. Following the presentation, the students broke into four groups of 8-10, which then rotated through different activity stations hosted by the teaching assistants.

This year’s activities included:

Canoeing and Prothontary Warbler Research — (Alissa Nicholsson)
The canoeing was difficult because of the strong winds and choppy waves on the James River. Yet, several groups did manage to enjoy the opportunity to see the Rice Rivers Center from the perspective of the river. From one of the student’s essay: “On the canoeing expedition, Alissa talked about the species that lived around the area and in the water. She also explained how the creek is tidal, meaning there is a high tide and a low tide. We canoed during the low tide time and it was very easy to touch the bottom of the water. We also got to see a blue heron and two bald eagles fighting over food during the time on the water.”   

Plant (Identification) Bingo — (Rebecca Dahlberg)
Rebecca led the plant identification activity with a Plant BINGO game that was created for the 2016 Rice Rivers Center Field Day. The packet contained identification guidelines and pictures of a variety of plants found at the center.  Students were asked to locate as many plants as they could find and collect samples if possible.  When the students found plants either on a diagonal or straight across they were to say “BINGO!”

Rock Identification — (Hannah Coovert)
Hannah guided the rock identification activity with the assistance of a rock sample kit generously provided by Dr. Arif Sikdar, assistant professor at the Center for Environmental Studies. She had the students examine and identify several different rock types.  Lindsay shared an amazing rock that her grandfather had found in Europe 80 years ago.

Measure Tree Attributes (DBH) and examining Soil Horizons from Upland to Wetland Zones— (Lindsay Schneider)
Lindsay led a nature walk to look at some trees. The students took turns measuring how much carbon each tree was taking out to the atmosphere by measuring up the tree about one meter and then taking the circumference of the tree using a DBH tape. Lindsay also encouraged the students to identify what types of trees that they passed. She then showed the students how to examine the soil horizons from the dry, upland area, down to the wetland area near Harris Creek.

By Leah Small, University Public Affairs

A Virginia Commonwealth University scientist is demonstrating that drone photography can be used for more than creating fantastic aerial shots and panoramas of landscapes. It has real-world applications in a variety of areas — from environmental science to defense and emergency response planning.

William Shuart, environmental technology coordinator for the VCU Rice Rivers Center and the Center for Environmental Studies, is currently using aerial imagery to create 3-D models of parts of the Monroe Park Campus. The models will be used in a mapping project by researchers funded by the Office of the Director of National Intelligence.

By Leah Small, University Pubilc Affairs

Crawling through neck-high mud on riverbanks is a dirty job, but someone has to do it for the sake of Virginia’s snapping turtles.

That task falls on Benjamin Colteaux, a Ph.D. candidate in Virginia Commonwealth University’s Integrative Life Sciences program, and other members of “Team Snapper” working in the lab of Derek Johnson, Ph.D., associate professor in the Department of Biology in the College of Humanities and Sciences.

For four years, the researchers spent several weeks at a time trekking through muddy turtle turf to catch and tag the animals, and record indices of health and growth for multiple studies on the impacts of wild turtle harvesting.

New assistant director of Center for Environmental Studies named

October 11, 2017

Dr. Rodney Dyer, director of the Center for Environmental Studies (CES), recently announced Dr. James Vonesh as assistant director of CES. Dr. Vonesh held the position of associate professor at VCU’s Department of Biology.

As assistant director, Dr. Vonesh will play a key role in the management and development of the ENVS undergraduate curriculum, bringing with him more than 10 years of teaching experience and a commitment to experiential and global education.

“Dr. Vonesh’s skill and expertise provide fundamental support to the ongoing transitions this unit is undertaking in both its research and curricular missions,” stated Dr. Dyer.  “I am tremendously excited to have him onboard and look forward to his help in guiding this unit forward.”

A broadly trained population and community-level ecologist and author of more than 50 scientific papers, Dr. Vonesh’s research has spanned from understanding how habitat fragmentation has affected forest chameleons in East Africa and frogs in North America, how predators shape the timing of metamorphosis in Central American tree frogs, to using mosquitos’ natural habitat preferences against them for more effective management. The current focus of his research is understanding how changes in predator biodiversity from extinction or species introduction will impact prey populations and ecosystem function and services.  

Dr. Vonesh was instrumental in the development of the “Footprints on the James” course which explores the interaction between history and the environment as students paddle down nearly 200 miles of the river. Recently, following a Fulbright Fellowship, he developed a similarly themed “South African Summits-to-Sea”, an expedition-style course in which students explore the intersection of freshwater resources, society, and biodiversity. He has also led field courses in Uganda, Tanzania, Taiwan, and Madagascar. “Ideally”, Vonesh says, “research and teaching are not compartmentalized but reinforce each other. A good example of this is our current work studying predator-prey ecology in the rock pools of the James River. This collaboration includes a world class team of ecologists, undergraduates from courses at VCU and University of Richmond, and Richmond Public High School students from Open High School and aims to advance STEM education and basic science.”

Dr. Vonesh’s work can be found at voneshlab.

“Autumn on the James” debuts at VCU Rice Rivers Center

October 6, 2017

(Pictured, from left to right: artist Guy Crittenden, VCU Life Science Director of Development Catherine Dahl, Rice Rivers Center Director Dr. Greg Garman)

A major painting was unveiled that captured the impact and beauty of the VCU Rice Rivers Center.

 “Autumn on the James,” by renowned Virginia wildlife artist Guy Crittenden, will hang in the reception area at the Rice Rivers Center Education Building. The 4 x 6 foot painting is from a birds-eye – or drone’s – view; Crittenden used drone photos to give perspective of the property from the air. The use of drone footage was a natural fit during the creation of the piece, as a course on the scientific application of drone technology is taught at the center.

Crittenden shares his thoughts on this important piece. “The project began with my first drive down the wooded lane off Route 5 which leads to the Rice Rivers Center. I was intrigued immediately with the landscape as I took twists and turns through the living forest. On that first visit, I was hooked. As talks about a painting progressed, I began to see this piece as a historically significant opportunity to render the land and water around the center. I wanted to give the viewer an eagle-eye perspective, and provide for them that sense of place, with all the relativity of the area’s landmarks.  Like the works of the 18th and 19th Century landscape artists I admire, this painting takes an interpretive approach to the traditional composition challenges, and uses light and color to hold the strong positive and negative shapes together. The landscape, river and marsh make a visually interesting composition, and if you look closely you will see native wildlife, the Benjamin Harrison Bridge, the town of Hopewell and the City of Richmond.”

The aerial view of the painting captures VCU’s River Campus in its totality. Although viewers cannot see the research being conducted in the James River or at the restored wetlands, the importance of the work done at the center contributes to the recognition of the facility and grounds as a nationally-significant academic research center.

“This remarkable piece of art places the Rice Rivers Center within a broad landscape context that includes natural systems like woods, wetlands, and water, while adding cultural elements such as the Benjamin Harrison Bridge and Richmond’s skyline. That composition is a great metaphor for the Center’s research and teaching mission,” says Greg Garman, Center Director.

We are delighted to be able offer limited edition prints of this painting, from a series of 150 numbered and signed by the artist, for a donation of $200 or more.  Please contact Catherine Dahl at ccdahl@vcu.edu or 804-827-7372 if you would like to make a donation to the Rice Rivers Center for this exclusive piece of art, or to obtain more information.  

A tough year for Chesapeake Osprey

October 9, 2017

By Bryan Watts, Center for Conservation Biology

 (Photo: Female osprey on nest with three-chick brood on a tributary of the Chesapeake Bay.  2017 was a poor year for osprey in the Bay.  Photo by Bryan Watts.)

The grumblings have gotten louder and louder over the past three years and have increasingly come from more corners of the Chesapeake.  By the end of the 2017 breeding season, the voices were loud and clear and singing the same tune.  The breeding season had been a dismal failure for osprey in the Chesapeake Bay.  Not just in one location but in all locations that were under observation.  Jan Reese reported that only 3 of 18 nests (17%) around Tilghman Island produced any young. Pam D’Angelo, observing on the Little Wicomico River, reported that the area produced almost no young. Reese Lukei reported that only 30 of 73 nests (41%) produced young on the Lynnhaven River, Pete McGowan reported that half of 23 nests monitored on Poplar Island failed, Greg Kearns working on the Patuxent River reported a 50% success rate, and CCB working on the upper James River recorded 26 of 57 nests (46%) that produced young.  The general sense of a poor season did not stem from the low success rate alone but also the reduced brood sizes.  On the upper James River surviving broods were mostly 1-2 young where in the past most successful nests produced 2-4 young.       

When Bob Kennedy monitored breeding osprey in the lower Chesapeake Bay as a student working with Mitchell Byrd during the early 1970s, hatching rates were only 36%, productivity rates were unsustainable, and the Bay-wide population had reached an all-time low of 1,400 pairs.  However, by the mid-1980s productivity had tripled and the population was experiencing rapid growth.  This growth would continue to the present time, reaching our current estimate of 10,000 breeding pairs for the tidal reach of the Bay.  Andy Glass, working in 2006 in the same study area as Bob Kennedy 35 years earlier, recorded 95% hatching rates.     

Observations and concerns over the past few years have led to questions about causation.  What is behind the success rates that are lower than what we have become accustomed to seeing?  Most biologists working with the population believe that failures are being driven by three factors, including 1) food stress from reduced fish stocks, 2) predation, and 3) poor weather.  Broods that are not provided enough food by adults to fuel growth form dominance hierarchies where high-ranking young get most of the food and low-ranking young get leftovers.  If the food shortage increases, the lowest ranking young will die in a process that we refer to as brood reduction.  In severe cases, all young will die and the nest will fail.  Lower brood sizes generally are indicative of brood reduction and are accompanied by low young weight or other behavioral signals.  As the populations of bald eagles and great horned owls have recovered from the DDT era and the number of mouths to feed has soared, the energy demand has spilled out onto species that would not be considered traditional prey.  Osprey fall into this category and there have been numerous documented broods lost to both predators.  Lastly, most raptors are susceptible to cold rains during the critical development period when eggs are near hatching or chicks are too young to thermoregulate on their own (first two weeks).  It is certainly possible that poorly timed storms could have caused some of the failures in 2017 and other years. 

All of these factors have likely been acting within the Chesapeake in recent years and have contributed to poor performance.  We do not currently know which of these factors may be dominant or how they may be distributed throughout the Bay.  You can help answer some of these questions by joining OspreyWatch and recording your observations about productivity of your nest.

 

Clutch Size in Chesapeake Bay Bald Eagles: An unexpected history

October 6, 2017

By Bryan Watts, Center for Conservation Biology

There was a time during the late 1800s through the mid-1900s when bird eggs were collected and sold or traded like stamps or coins.  During this period, bald eagle eggs were valuable and in demand.  The price for a single bald eagle egg was listed as $15.00 in the 1922 American Oologist Exchange Price List of North American Eggs.  Due to the general interest in eagles and the value of their eggs, eagle egg collectors were widespread throughout North America.  Several major collectors including Harold Bailey, Fred Jones, Edward Court, Richard Harlow, and Willet Griffee were active in the Chesapeake Bay through the 1940s.  Each had their own collecting area that seemed to be respected by gentlemanly agreement but all were highly secretive about the location of prized nests where they collected.

Although eagle egg collecting has now gone the way of the stagecoach, compilation of clutch sizes from egg collections provides exciting new insight into the ecology of eagles during a time period before the introduction of DDT into the estuary.  Compared to all other accounts throughout the species range, clutch size within the Chesapeake Bay during this early time period was extraordinarily high, averaging 2.46 eggs.  In his remarkable book, The Bald Eagle, Mark Stalmaster summarized 16 studies from throughout the breeding range that reported clutch size and indicated that 17% of clutches contained only one egg, and only 4% contained more than two eggs.  In stark contrast to this finding, 3.3% of clutches collected in the Bay contained only one egg and 43.0% contained three or more eggs. 

Amazingly, eagle egg collections from the Chesapeake included three four-egg clutches and two five-egg clutches.  Although rare, four-egg clutches have been documented in recent times within the Chesapeake including three four-young broods.   The five-egg clutches are an oddity and have not been reported previously within the bald eagle literature.  The clutches were collected by E. J. Court, who was a prolific collector for more than 30 years along the upper Potomac River below Washington, D.C.  Examination of the collection notes provides confidence that these clutches were real.  The possibility that these clutches resulted from contributions of two females cannot be resolved.  Incredibly, the two clutches were collected from the same territory just two years apart.  The territory was on the Virginia side of the Potomac in a site known commonly as Crow’s Nest, which continues to be a center of eagle activity to the present day.  The circumstances that lead to these clutches are unclear, and because they were collected we are left to wonder if the pair could have hatched all five eggs and raised the young to independence.

One of the most surprising discoveries from looking back through the historic clutch record is that bald eagle clutch sizes have changed dramatically over the past century.  By the time the aerial survey was initiated in the early 1960s, the average clutch size had been reduced by nearly half compared to the period of egg collecting that closed merely 20 years before.  During the 1960s and 1970s, 20 (66.7%) of 30 documented clutches were single eggs and only one (3.3%) contained three eggs.  By the 1980s and 1990s, clutches were trending larger with only 26.8% (N = 56) single egg and 16.1% containing three eggs.  Although recovery is not complete, after the year 2000 clutches have begun to resemble those in the early 1900s, with only 4.0% (N = 99) single eggs, 66.7% two-egg clutches, and 29.3% three-egg clutches. 

The impact of legacy contaminants such as DDT on egg hatching rates, young survival, and even adult mortality from the 1950s through the 1970s has been reasonably well documented.  A retrospective assessment of clutch size within the Chesapeake Bay suggests that contaminants likely caused a direct suppression of clutch size as well. 

 

No good news for Eastern Black Rails in NC and GA

October 4, 2017

By Bryan Watts, Center for Conservation Biology

(Photo: Eric Sibbald records data during a survey along the North Carolina coast.  Photo by Rob Colquhoun.)  

The eastern black rail is listed as endangered in six states and is currently under review for federal listing.  In 2016, The Center for Conservation Biology worked with many partners to produce a status assessment in support of the federal process.  Among other things, this assessment identified gaps in survey coverage.  During the 2017 breeding season, CCB worked with the North Carolina Department of Natural and Cultural Resources and the Georgia Department of Natural Resources to help fill information gaps within the two coastal states.  Survey teams were deployed in both states to survey a network of sites within designated high-priority areas and assess black rail occurrence during the breeding season.  The surveys continue ongoing efforts by the Eastern Black Rail Working Group to collect information on status and distribution.  Since 2014, the partnership has surveyed more than 6,000 locations for black rails within coastal habitats.

A network of 691 point locations was surveyed for black rails during the 2017 breeding season, including 284 in North Carolina and 409 in Georgia.  The network was surveyed three times between 18 April and 21 July using a standard call-back protocol, resulting in the execution of 1,983 point counts.  Surveys in North Carolina targeted coastal regions that were not included in the 2014-2015 effort conducted by CCB.  The only exception to this was Cedar Island, which has historically been the center of activity in the state.  No formal surveys of black rails have been conducted in Georgia so the network covered the entire Coastal Plain in an attempt to determine status and distribution.

Black rails were detected within only 4 (0.6%) points and during only 5 (0.3%) of the point counts conducted across both states.  Detections were only made in North Carolina and only on Cedar Island National Wildlife Refuge, an area already known to support these birds.  The extensive survey effort resulted in the detection of no new occupied sites.  The effort has provided closure to some of the identified information gaps.

Results from the 2017 effort are discouraging and are consistent with observations across much of the Atlantic Coast over the past decade.  Black rails have experienced a catastrophic range contraction from northern breeding areas that is progressing southward.  Efforts are continuing within the Eastern Black Rail Working Group and other appropriate committees to identify management options that will stabilize remaining strongholds and slow the ongoing decline.    Survey efforts will continue in both North Carolina and Georgia during the 2018 breeding season to fill remaining information gaps.

 

 

 

 

Students demonstrate validity of models that use free, publicly accessible climate data

October 4, 2017

By Leah Small, University Public Affairs 

(Photo: A sunrise over Crown Point at Columbia River Gorge. Students of Daniel McGarvey, Ph.D., used widely available climate data to model fish distributions in the waterway.)

As concern about the consequences of climate change grows, researchers are thinking hard about the data and models that drive their understanding of these changes.

Graduate students in Virginia Commonwealth University’s Center for Environmental Studies recently contributed to this effort by proving that free, publicly accessible climate data can predict habitat quality within river networks with as much accuracy as data from more complex and expensive sources. Climate data includes variables such as precipitation and air temperature. Scientists place these variables into models created to make predictions regarding environmental changes such as species distributions.

Many of the data sources needed to model climate change effects are available online at no cost to both the scientists and lay users, which alleviates the financial burden associated with many scientific inquiries, said Daniel McGarvey, Ph.D., associate professor in the Center for Environmental Studies in VCU Life Sciences.

Reese Lukei, Jr.

October 3, 2017

By Bryan Watts, Center for Conservation Biology

(Photo: Reece rescuing a bald eagle nestling after nest fell out of a tree at Mackay Island National Wildlife Refuge)

One half hour before dawn we walked the trail in darkness with no conversation, placed the supply of lure birds behind the blind and began the work of setting up the trapping station.  A strong cold front the day before had resulted in a push of raptors into the lower Delmarva and we knew that birds would be roosting in the shrubs around us.  They would soon be out and hunting for breakfast.  The front had continued through the night, the air was crisp and full of the electricity that would bring more waves of raptors through the day. Reese fixed a pigeon to the high pole and a starling to the low pole, set the bow traps and checked all of the pull lines while Marian and I opened the mist nets and arranged the equipment within the blind.  The site was of Reese’s design, reflecting his trapping style and years of tinkering to improve efficiency.  It was now a fine, hand-made instrument that could be played on demand.

We sat in the blind squinting out into the dim for any movement until a Cooper’s hawk circled out to the west.  Reese immediately turned the bird with a single pull of the pigeon, letting it resettle, then drew the bird across the site and into the central mist net with the starling. The ice was broken.  Over the next two hours we processed 25 birds as quickly as we could manage, alternating between retrieving and processing birds while keeping the site open for incoming.  By 10:30 the stream began to slack and we had reached the midday doldrums.  Reese turned on an obscure concerto on the boom box hanging in the blind and began to conduct with vigor, summoning the French horns and violins to the lead and then driving the entire orchestra to a dramatic climax.  The piece ended with a peregrine floating over the site.  She glanced down at the pigeon but turned her nose up, a sure sign that she had dined elsewhere.  We trapped through the day, catching mostly accipiters but also two late merlins, two early red-tails, and one cautious harrier.  We closed the day as we began with two Coops hunting for a meal as they settled into the shrubs for the night.  In all, more than 50 raptors banded.

The dawn to dusk schedule was a hallmark of Reese’s effort, running the trapping site for 20 years as a research associate of The Center for Conservation Biology.  During that time, he banded more than 10,000 raptors, documenting the recovery of eastern peregrines, a changing of the guard between Cooper’s and sharp-shinned hawks, the passage phenology of several species, and many other details of raptor migration ecology.

Those of us who work in the conservation industry eventually have to confront the big question – Why are we doing this?  Reese never seemed to struggle with this dilemma.  Reese retired early as a partner in an accounting firm not to end a career but to begin his life’s work.  Many of us retire to focus on ourselves with a sprinkling of service.  We volunteer enough to ease our good-citizen minds but not so much that it cramps our golf schedule.  Reese retired to spend his life in service.  Not just to bird conservation but to making the broader community better.  He has lived the past 30 years working through an endless list of good acts.  His dedication has exemplified what it means to be a global citizen.

Reese’s work has focused on three enduring passions including hiking, conservation, and people.  He has hiked in all 50 states and in more than 70 countries. He has completed the entire Appalachian Trail and 1,500 miles of the American Discovery Trail.  Reese has not just hiked trails, but has established, designed, built, and maintained them, as well as served on the boards of many trail organizations.  He was the co-founder and national coordinator for the American Discovery Trail for 12 years, testifying before congress and helping to get the trail established.  He has received many awards for his trail work including, in recent months, a lifetime achievement award from the National Trails System and a lifetime service award from the American Discovery Trail Society.  I suppose that both the work and the awards reflect the fact that Reese has never shied away from taking on the big roles when called upon.

Reese has always had a passion for raptors, an affliction that wife Melinda has called “an incurable disease.”  His introduction to banding was with famed migration banders Walter Smith, Charlie Hacker, Mitchell Byrd and Fred Scott.  He began trapping passage peregrines in the late 1970s in an effort that would expand to include running the Wise Point Raptor Station, breeding-season osprey, and bald eagle banding.  He has monitored nesting osprey and bald eagles in the urban areas of lower Tidewater, Virginia for decades, assisting with the state-wide efforts conducted by CCB.  In recent years as the populations have grown, this has become an all-consuming effort during the breeding season.  Reese has volunteered for an estimated 30,000 hours on planning, construction, and maintenance projects for national wildlife refuges and national parks across the country.  This lifelong commitment to these properties has resulted in many awards and acknowledgments over the years.  

Reese never met a stranger.  Beyond the trail work and raptor monitoring, his most enduring legacy will be his dedication to and passion for bringing people closer to nature.  He has used his own passion for nature to infect others with the incurable disease and by doing so has recruited others to the conservation cause.  He has rarely refused a speaking request and has given over 700 public talks about birds and trails.  In short, he has shown up on game day whenever the call has gone out.  He ran the commentary for the Norfolk Botanical Garden Eagle Cam and continues to operate the eagle blog for CCB.  For many people, their first introduction to raptors or to conservation service has been through Reese.  He has been a tireless ambassador for nature.

The day in the trapping blind and many others echo a general message of success.  If you are going to do something then do it well, with passion and style.  The answer to the big question that Reese seems to have always known is that we work in conservation to leave the world a better place for other species and by association ourselves.  The Center for Conservation Biology wants to join many other organizations in thanking Reese for his lifelong commitment to bring people and wildlife together, and for raising the awareness of conservation issues and making the world a better place.  Thanks, Reese.

Hope survives

September 14, 2017

By Bryan Watts, Center for Conservation Biology

Irma, the storm that began as a puff of wind off the western coast of Africa and became a monster over the warm waters of the Atlantic, left a path of devastation stretching more than 2,000 miles.  Irma was the strongest storm ever to exist in the Atlantic Ocean outside of the Caribbean and Gulf of Mexico and sustained 185 mph winds for 37 hours, the longest of any storm ever recorded.  Irma hit the Leeward Islands during the peak of her strength causing loss of life and historic destruction of property.  This pattern would continue through Puerto Rico, Cuba, Florida, and the Carolinas.  Now, as Irma whimpers off to the north as a tropical depression, people are venturing out to assess the damage and to begin the process of recovery.  Our thoughts are with all of those who have been impacted.

Hope is a whimbrel that breeds in western Canada on the Mackenzie Delta and spends the winter months at Great Pond on St. Croix.  She is well-known to the public as a bird that was tracked using a satellite transmitter by The Center for Conservation Biology for more than 50,000 miles between 2009 and 2013, and to many children as the hero of the children’s book written by Cristina Kessler titled “Hope is here.”  Hope was on her winter territory when Irma hit St. Croix and many have wondered about her condition after the storm has passed.

Local ecologist Lisa Yntema visited with Hope on Great Pond on the morning of 26 August, 2017 and photographed her on the mudflats.  She had only recently arrived from her Arctic breeding grounds.  Just 11 days later on 6 September St. Croix was hit by Irma.  Many of us wonder how birds and other wildlife cope with extreme storms.  Lisa ventured out to check on Hope on the morning of 11 September and found her to be her usual “noisy self.”

Hope has taught the research community a great deal about the migratory pathways and habits of whimbrels.  She has made tremendous nonstop flights, moved great distances out over the open Atlantic, confronted storms while at sea, navigated with precision to stopover sites, and shown high fidelity to her breeding site, her wintering site, and several staging areas.  She has encountered a great deal living a life on the edge but continues to be a survivor.

The leaving ecology of whimbrel

September 13, 2017

By Bryan Watts, Center for Conservation Biology

We have spent years standing on Box Tree Dock listening for their rallying calls through the chorus of laughing gulls and clapper rails and looking south for them to rise over the horizon of marsh.  For many whimbrels, this is the last time they will touch the ground until they land on their Arctic breeding territories.  As flock after flock have passed overhead, we have logged their numbers in the hope of better understanding their “ecology of leaving” and how this event figures into their annual cycle.  The Delmarva Peninsula in Virginia represents a refueling site for whimbrels moving from winter areas in Brazil to Arctic breeding grounds.  What time of the day do most of the birds form up flocks and take off?  What is the distribution of flock sizes that leave?  What is the spring departure schedule?  These questions provide a glimpse into the many factors that have shaped their migration.  Like all ecological projects, it has been a journey of discovery.  At the close of each day we have hung onto each bit of information trying to make out the grander view.

Recently, we have compiled WhimbrelWatch data collected between 2009 and 2014 and published a paper entitled Departure patterns of Whimbrels using a terminal spring staging area in the journal Wader Study.  During the six-year period, we recorded 727 whimbrel flocks leaving the lower Delmarva that contained 39,720 birds.  Amazingly, the peak leaving date varied only three days (23 to 25 May) across six years.  During these peak leaving times, flocks were recorded every six minutes on average and the leaving rate exceeded 600 birds per hour.  Departures peaked approximately 2.5 hours before civil twilight with 82% of individuals leaving within the two-hour period between 1.5 and 3.5 hours before twilight.  Flock size ranged as high as 270 individuals and average flock size varied throughout the afternoon, with the largest flocks leaving during the onset of exodus.  The distribution of departing flock sizes approximated a negative exponential as smaller flocks were more common.  The result of this pattern is that although 50% of all flocks recorded contained less than 35 individuals, 50% of all individuals occurred in flocks that contained 80 individuals or more. 

Group travel in shorebirds is believed to provide benefits to flock members such as collective navigation and energetic savings related to flock aerodynamics.  These possible benefits for flocking have not been tested in whimbrel.  The highly synchronous and consistent departure pattern may help to facilitate synchronous arrival on the breeding grounds and reinforce mate fidelity.  Nesting season in the high Arctic is very short, placing a premium on preparations that allow birds to take advantage of breeding opportunities as they arise. 

Over the years, Box Tree Dock has become a window on whimbrel migration and a gathering place for many offering educational opportunities for school groups and a venue for birding groups and individuals.  We thank all of those observers who have contributed to the success of WhimbrelWatch.

 

 

Regina Jefferson retires from VCU

September 6, 2017

There aren’t too many people who can say they spent their entire career with one organization, but 42 years and eight months later, Regina Jefferson can make that claim.

On Thursday, August 31, Ms. Jefferson’s long tenure at VCU was celebrated as friends from all over the university and family gathered in one of the salon rooms at the University Student Commons.

Ms. Jefferson started her employment with VCU in 1974 as a clerk typist in the School of Dentistry’s Faculty Practice. After almost two years, she moved to the School of Nursing and became one of the first employees in the newly-established pediatric nurse practitioner program. Ms. Jefferson completed seven years of service in that growing unit, but decided to return to the School of Dentistry when an administrative position became available.  For 21 years, she was a familiar face to students and faculty while working with Dr. Marshall P. Brownstein, assistant dean of admissions and student affairs.

Upon Dr. Brownstein’s retirement, Ms. Jefferson moved to Life Sciences, where she has held the position of executive assistant to the vice provost since 2003. She has provided invaluable support to Dr. Thomas F. Huff, Dr. Leonard A. Smock, and Life Sciences’ current vice provost, Dr. Robert. M. Tombes.

“I am happy that I was able to be there on her day of celebration and honor her contributions to VCU and Life Sciences,” said Dr. Tombes. “She not only anchored many of our schedules and events, but her wisdom and experience served as a steady influence on all of our operations. I will miss her, but fortunately, her kids and grandkids will get more time to enjoy her infectious laugh and smile.”

Ms. Jefferson is already making plans on how to spend her well-deserved retirement, with a lot of traveling, relaxing, spending time with her grandchildren, and not setting her alarm to wake up.  

Data-driven

August 29, 2017

When Heather Spencer Lansdell began her externship at the National Institute for Environmental Health Sciences in the Office of Data Science, she didn’t realize the enormity of the project she was about to undertake. Over three months, her charge was to wrangle and manage data to support a greater project, the upcoming NIEHS Data Commons initiative. The results of her findings were shared in her final presentation to complete her Master of Science in Bioinformatics, "NIEHS Metadata Catalog: Developing a foundation for bioinformatic analysis and data management."

Lansdell’s journey into the world of scientific metadata didn’t begin with a background in science – she holds a BA degree in Interdisciplinary Studies from William & Mary with a focus on Literary and Cultural Theory.  It was while she was working at the Ellen Shaw de Paredes Institute for Women’s Imaging when a colleague noticed her analytical skills and penchant for working with data.  VCU’s bioinformatics program was discovered as a possible pathway to build on that ability, and after taking a few undergraduate prerequisite courses, Lansdell fully entered the Professional Science Master’s program in Bioinfomatics in spring 2015. This degree program features an externship at an industry or government lab, which Lansdell completed this summer.

Once she started to immerse herself in the project, Lansdell quickly found there were some common denominators as to why it can be so difficult to grapple large amounts of data. One of the biggest obstacles continues to be the lack of a common language used for storing data. Metadata is input by individuals and categorized by words, but if there isn’t a universal protocol on how to best use the words for tracking and storing, searching for data can become laborious. This project will allow many different types data, including legacy data, to be easily discoverable through the use of metadata tagging of datasets.

Another challenge is making the data available to all.  Presently, Lansdell’s work is a pilot program internal to NIEHS.  Lansdell is an advocate for sharing data, and the goal is to make it open source. “The goal is that data ownership remains with researchers and labs, but they participate in collaboration with others,” she said. “We hope to be a resource for the entire environmental health services industry.”

Lansdell’s externship required her to evaluate new technologies for managing metadata, create a prototype tool for implementing the optimal features, and extract and store data from a variety of sources.  While these skills aren’t specifically taught in courses, Lansdell’s ability to quickly learn new technologies and approaches and to effectively solve problems led to her success on the project.  Lansdell is just one of VCU’s Professional Sciences Master’s candidates that have benefitted from the program’s flexible curriculum that can be customized towards the student’s abilities and interests.  Students are closely advised to help chart their educational course, and are asked to complete “bridge courses” to fill in any areas of weakness.  Faculty from the program work with students from a variety of STEM backgrounds, as well as other students who might not have the core requirements for immediate entry into the program, but are highly motivated to begin their career in this rapidly growing field.

Garden Grove Brewing Company to host sustainable and invasive species dinner benefit for Rice Rivers

August 23, 2017

By Leah Small, University Relations

Most local diners haven’t feasted on fried snakehead fish or drank beer infused with spice bush leaves that have a summery, citrus taste. Food and beer aficionados will be introduced to these and other adventurous offerings during a Rice Rivers Center benefit, part of the Garden Grove Brewing Company’s monthly Taproom Dinner Series.

The event will be held Monday, Aug. 28, at the Garden Grove Brewing Company. Tickets can be purchased on Garden Grove’s website.

Garden Grove head brewer Michael Brandt and Southbound restaurant chef Craig Perkinson will offer beer, wine and food selections paired or created to capture the Rice Rivers Center’s mission to conserve and study Virginia waterways. Each offering will consist of either a native or invasive plant or animal species found in Virginia.

Rice Rivers Center recipient of first Garden Grove benefit dinner

August 21, 2017

On August 28, Garden Grove Brewing and Urban Winery will be hosting a unique dinner menu where guests will be able to dine on selections made with Virginia invasive and sustainable ingredients. Chef Craig Perkinson of Southbound will be preparing the delicacies for the multi-course meal. 

Guests will also have an opportunity to meet and enjoy a presentation from VCU Rice Rivers Center Director Dr. Greg Garman.  Dr. Garman will discuss the Rice River Center’s work restoring Virginia sturgeon populations, wetlands, Virginia Oyster Shell Recycling Program, and improving water quality. Deputy Director Dr. Ed Crawford and Virginia Oyster Shell Recycling Program Director Todd Janeski will also talk about their work at the center.

Each course will be paired with one of Garden Grove’s beers or wine.  Some of the selections from the five course dinner include:

  • Autumn Olive Saison (made with berries from the invasive Autumn Olive shrub/tree) with a whole hog dish utilizing Autumn Olive Farms Pork
  • Garden Grove’s award winning Belgian Dubbel, Minor Threat and the Funkadelic 4, with the invasive fish species Blue Catfish
  • Spice Bush Belgian Gold, paired with J.C. Walker Virginia Clams and the invasive fish species, Lionfish.  The spice bush leaves used to make the Belgian Gold were collected locally by VCU Rice Rivers Center Deputy Director Dr. Edward Crawford.

Unlike previous meals in the Taproom Dinner Series, a sixth course will be served as a thank you to those supporting the VCU Rice River Center and Garden Grove’s first Charity Dinner. That course will feature a surprise dessert paired with Garden Grove’s house made Thai inspired lemongrass ginger ale.

Reservations are required and tickets are limited, with only a few remaining. Learn more and register here.

VCU alumni recognized for outstanding presentation

July 28, 2017

Earlier this year, Spencer Tassone, a 2017 master’s graduate in Biology, gave an oral presentation at the spring 2017 Atlantic Estuarine Research Society (AERS) meeting at St. Mary's College in Maryland.  Part of Tassone’s Master’s work and research that appeared in the presentation was conducted at VCU Rice Rivers Center. 

Titled "Seasonal and Interannual Variation in Metabolism of the Tidal Freshwater James River", it was awarded “Outstanding Graduate Student Presentation” of the conference.  Tassone told how he examined the total amount of gross primary production (photosynthesis) and ecosystem respiration (decomposition) every 15 minutes across an eight-year span using data collected off of the Rice Rivers Center pier, resulting in a staggering 280,000 data points.  

This wasn’t the only achievement Tassone received this year. He was recently named “Outstanding Biology Masters Student in Ecology” by Montserrat Fuentes, Ph.D., Dean of VCU College of Humanities and Sciences. Nominees for this award are evaluated based on their GPA, courses taken, research experience, professional preparation, publications, presentations at meetings and service to VCU. 

Tassone now brings his talents to VCU as a new staff member in the Department of Biology working under Paul Bukaveckas, Ph.D. on river and estuarine ecology in the York, Pamunkey and Mattaponi Rivers, which will complement ongoing work in the James River Estuary.

Science Matters spotlights the Virginia Oyster Shell Recycling Program

July 24, 2017

Science Matters, a multi-media educational initiative of the Community Idea Stations, turned the spotlight on our Virginia Oyster Shell Recycling Program (VOSRP).  The Community Idea Stations include Richmond's PBS and NPR affiliate stations.  

Ron Lopez, a 2017 master's graduate of VCU's Center for Environmental Studies, created a three-minute film explaining the journey of an oyster shell through the view of the shell. The film also explains how the VOSRP works, from the time the oysters are harvested to when the shells are returned to the Bay.  The three-minute version is highlighted on the Community Idea Stations' website, with additional information available about the VOSRP. A shorter, one-minute version of the film was accepted to air between programs on WCVE and WHTJ television.

National Park Service and CCB continue to assess exposure of eagle nestlings to contaminants

July 14, 2017

By Bryan Watts, Center for Conservation Biology

The National Park Service (NPS) is the keeper of our most precious crowned jewels.  It manages the places that hold the essence of our history, culture, and natural wonders, the spectacles that we describe with pride to visitors that travel from other nations, and the inspirational vistas that we all run to for solitude and contemplation.  In addition to their cultural importance, this portfolio of lands is also the infrastructure that supports our most imperiled wildlife. We, as a people, entrust all of these most valuable possessions to the staff of the National Park Service - a charge that they accept with pride and commitment.

National parks have been instrumental in the recovery and maintenance of many threatened species and often support the best remaining examples of intact ecosystems.  They have played a critical role in the recovery of bald eagles.  Within the Chesapeake Bay, colonization rates and subsequent breeding densities of eagles on park lands have far outpaced those on private lands.  Parks now support a significant number of breeding pairs.  Although these parks are managed with a mandate to provide habitat for existing territories, breeding pairs should not be considered secure due to the continuing risk of exposure to environmental contaminants emanating from external sources. Park Service biologists understand that managing wildlife populations often requires mitigating risks coming from outside park boundaries, and that park properties often represent some of the best opportunities to monitor the health of larger systems that contain them.

For a second breeding season, CCB and NPS biologists collected blood samples from nestling bald eagles from park lands within the Chesapeake Bay to monitor for contaminant exposure.  The 2017 effort focused on park lands along the Potomac River, including The National Capital Region.  Blood and other tissues were collected from 11 eagle broods.  The ongoing study is a collaborative effort with eagle biologists from the Great Lakes and will compare contaminant exposure experienced by eagle broods in the Chesapeake Bay to those reared on NPS lands within the Great Lakes Region.

James River eagle recovery enters final chapter

July 12, 2017

By Bryan Watts, Center for Conservation Biology

One of the enduring questions in population ecology is: what determines the size of a population?  Stated another way:  what are the factors that regulate population size?  One of the classic approaches of investigating regulatory mechanisms is to study a population over time that has either recently colonized a new habitat or is rebounding from a catastrophic event.  Investigating a population that is growing within an effective “vacuum” allows us to observe its behavior as it increases and approaches capacity. 

During the height of the DDT crisis, the James River supported no breeding bald eagles for a period of five years during the 1970s.  The once-thriving population was diminished as productivity sank to levels below that needed to offset adult mortality.  Over an 11-year period during the 1960s and early 1970s, eagles on the river produced only three young.  After DDT was outlawed in the United States, the James River was recolonized by breeding eagles and productivity rose through the 1980s, leading to dramatic population growth.  Annual surveys have documented the phenomenal recovery that continues through the 2017 breeding season.  The breeding population has experienced tremendous momentum over recent decades, increasing from 18 pairs in 1990 to 57 pairs in 2000 to 272 pairs in 2017. 

As we have witnessed the population advance every year since the late 1970s, the central questions remain:  How high will the population rise and what are the underlying regulatory mechanisms that will constrain it?  Although the population continues to increase, the long-term trend in productivity gives the first real signal that we have entered the last chapter of the recovery.  The average number of young produced per breeding pair reached a peak during the late 1990s and has shown a gradual decline since this time.  The rate has now contracted back to levels not seen since the 1980s.  The continued decline of productivity back down to or near maintenance levels is the demographic response that will ultimately constrain the population and bring it to some form of equilibrium.

Why is productivity declining?  The recovery in productivity throughout the 1980s and 1990s drove exponential growth in the breeding population.  Beginning in the late 1990s, actual growth of the population began to diverge from that expected based on the number of young produced.  This divergence created an increasingly large population of floaters (breeding-age birds that do not hold territories) setting up a class war between the haves and the have-nots.  We believe that the disruption of breeders by floaters represents the negative behavioral feedback that is pulling down productivity and will ultimately bring the population into equilibrium with available breeding space.

Late arrival and breeding in juvenile-plumaged night herons

July 11, 2017

By Bryan Watts, Center for Conservation Biology 

Age to first breeding is a relatively consistent trait across heron species and typically coincides with the attainment of adult plumage.  For most migratory herons, juvenile-plumaged birds oversummer on the winter grounds and are infrequently observed around breeding colonies.  Yellow-crowned night herons transition into adult plumage in the summer of their third year (fourth calendar year) and presumably migrate to breeding grounds the following spring to breed for the first time.  Past surveys of yellow-crown colonies have documented that juvenile-plumaged birds account for less than 3% of breeding individuals.  However, very little is known about the circumstances of breeding in younger age classes.  As part of the ongoing investigation of yellow-crown breeding phenology, particular attention has been given to birds in juvenile plumage, their arrival times, and gender, in order to increase what we know about the rare young birds that breed.

Young night herons arrive late, lay eggs late, and are predominantly females.  In recent years, weekly monitoring of yellow-crowned night herons has focused on 10 colonies supporting 95 pairs.  During the 2017 breeding season, seven pairs contained juvenile-plumaged birds and all juveniles were mated with adult-plumaged individuals (<5% of breeders were juveniles).  Two individuals (both females) were in first-year plumage and the remaining birds were in second-year plumage.  Pairs containing young individuals were the last to arrive and the last to complete clutches.  Seven of the nine juveniles observed to breed were females, based on behavior. 

Little is known about the ecology and distribution of juvenile yellow-crowned night herons between the time of independence and the time they return to the breeding grounds in adult plumage.  Unlike many species where early breeding has been reported, juvenile yellow-crowns are not associated with breeding areas as nonbreeders.  Because of this, it seems unlikely that conditions on the breeding grounds would trigger the migration and breeding of young birds.  No definitive information is available on the formation and maintenance of pair bonds.  The arrival of paired juvenile and adult birds on the breeding grounds suggest that pair bonds likely form on the winter grounds and that demographic conditions during winter may induce juvenile migration and breeding.

Cliff swallow population explosion continues in coastal Virginia

July 6, 2017

By Bryan Watts, Center for Conservation Biology 

Cliff swallows are a wonder to see up close.  Adults are richly colored in a combination of deep chestnut, cream, blue, and salmon that is reminiscent of the earthy colors of their winter grounds in the lowlands of Argentina, Paraguay, and southern Brazil.  Following spring arrival on the breeding grounds, pairs gather mud by the mouthfuls and craft unmistakable gourd-like nest structures.  Historically, these structures were built on exposed cliff faces under overhangs.  With the expansion of artificial structures throughout the continent the swallows rapidly adapted, attaching their nests to barns, dams, culverts and bridges, and expanding their range beyond the western mountains.  Over the past 150 years cliff swallows have marched across the continent, disappeared from some regions, and more recently mounted a selected resurgence.

The Coastal Plain of southeastern North America is experiencing a swallow boom.  The most recent colonization of this physiographic region began 50 years ago when birds moved across the Piedmont and began to establish footholds on bridges of the inner Coastal Plain.  In Virginia, Fred Scott of Richmond recorded the first breeding record within the Coastal Plain in 1979, when he documented 12 nests on the Benjamin Harrison Bridge along the James River near Hopewell.  In 1995, The Center for Conservation Biology conducted a systematic survey of breeding areas throughout the Coastal Plain of Virginia to establish a population benchmark and to document geographic expansion.  During the breeding seasons of 2016 and 2017, this effort was repeated in order to establish a second benchmark.

Since 1995, the cliff swallow population has increased nearly seven-fold in coastal Virginia from 454 to 3,052 pairs within 11 colony sites.  The largest colony site, supporting more than 1,000 pairs, continues to be on the Benjamin Harrison Bridge.  Since their discovery in 1979, the population has grown exponentially with an average doubling time of just 4.8 years and has continued to expand geographically. 

Breeding cliff swallows require surfaces protected from the weather and predators, a source of mud to construct their nests, and swarms of flying insects to raise broods.  Bridges are ideal places for nesting because they provide both protected surfaces and access to mud along their banks.  However, only 10% of the bridges surveyed currently support swallow colonies.  One of the most interesting aspects of the current breeding distribution is that all occupied bridges occur within tidal-fresh reaches of rivers where salinity is low, presumably facilitating high insect production.  Work is needed to clarify the link between salinity and insect production that may help to clarify constraints on distribution as the ongoing colonization plays out.

Woodpecker partnership records first success within the Great Dismal Swamp

June 26, 2017

By Bryan Watts, Center for Conservation Biology  

Conservation partners are celebrating the first successful breeding of the endangered red-cockaded woodpecker within the Great Dismal Swamp National Wildlife Refuge.  Two young woodpeckers were banded on the 20th of May and flew from the nest cavity during the second week of June.  This event represents a milestone in an ongoing effort to establish a breeding population within the refuge.  A total of 18 woodpeckers were moved into the site during the falls of 2015 and 2016 by a broad coalition including several units of the U.S. Fish and Wildlife Service, the Virginia Department of Game & Inland Fisheries, The Center for Conservation Biology, The Nature Conservancy, and many volunteers. 

Similar in appearance to downy and hairy woodpeckers that are widely recognized and common “backyard” birds, the red-cockaded woodpecker has a much more specialized ecology.  Red-cockadeds require old-growth pines and are primarily associated with fire-maintained pine savannahs of the Deep South.  The shift to shorter rotation forest management and fire suppression virtually eliminated their historic habitat and ultimately led to their federal listing as endangered in 1970.

Red-cockaded woodpeckers in southeastern Virginia currently represent the northernmost population known.  Throughout the latter half of the twentieth century this population experienced a catastrophic decline, reaching a low of only two breeding pairs by 2002 (read more about their population decline in Virginia, Watts and Bradshaw 2005).  Heroic efforts to save the species on the only remaining site (the Piney Grove Preserve owned by The Nature Conservancy) have stabilized and increased the population to 14 breeding groups.  However, there has been ongoing concern from the conservation community about the risks of relying on a single site that could be destroyed by a hurricane or other natural disaster.  Establishing a second breeding population within the state has been a stated priority for more than a decade (read more about Virginia recovery objectives, Watts and Harding 2007).

Early in the year the likelihood of breeding within the swamp seemed like a long shot for 2017.  During the run up to the breeding season only five of the eighteen birds that had been moved from other populations remained within the refuge, including two males and three females.  All of these birds were isolated from each other in scattered sites.  By early May birds had formed two breeding pairs and soon each had laid three-egg clutches.  All three of the eggs from the first clutch hatched on 13 May, but only two of these young survived to be banded on 20 May.  One of the two birds was grossly underweight, weighing just over half as much as the other bird.  A check on these birds when they were 20 days old revealed that they were both doing fine and both were females.  The young birds were observed with the adult pair flying tree to tree foraging when they were approximately ten days out of the cavity.  The three-egg clutch laid by the second pair disappeared just before hatching (likely taken by a predator).    

Successful breeding of red-cockaded woodpeckers within the Great Dismal Swamp during the 2017 season represents a small but significant step in the long recovery of the species along the northern fringe of its breeding range.  Having the two locally-produced females making their way in the habitat of the swamp increases the population and is a real win for the conservation partnership dedicated to recovering this unique species.

Celebrating 10 years of Black Lights and Owls at VCU Rice Rivers Center

June 1, 2017

Hurricane-like rain and a fierce electrical storm didn't keep many away from the VCU Rice Rivers Center on the evening of May 27.  Beginning at 7 p.m. Saturday through 9 a.m. Sunday,  Rice Rivers Center hosted Black Light and Owls, also known BLO.  Entomologist Dr. Art Evans and VCU Life Science Outreach Director Anne Wright led the tenth annual all-night celebration documenting the noctural riches of Charles City County, Virginia.  

When the skies cleared, the group was able to move outside to view the insects that were attracted to ultraviolet and mecury vapor traps, and walk the grounds in search of owls. A side-visit to the Harrison Lake National Fish Hatchery featured a thunderous and mighty frog chorus.

The participants that chose to stay the night enjoyed a pot luck dinner and a chance to camp out on the bluff overlooking the James River, or inside the VCU Rice Rivers Center Education Building, Virginia's first LEED Platinum building.

Fulbright scholar Ellen Korcovelos uses computer science and speech analysis to combat dementia

May 18, 2017

By Leah Small, University Public Affairs

When recent VCU graduate Ellen Korcovelos emailed her idol, a researcher who is one of the best and brightest in his field, she didn’t imagine he would fulfill her request to meet him, let alone invite her to travel to Toronto to conduct research in his lab.

Korcovelos, who earned an undergraduate degree in bioinformatics from the School of Life Sciences’ Center for Biological Complexity and a minor in computer science in the School of Engineering, couldn’t believe she had the opportunity to learn from Graeme Hirst, Ph.D., a leading researcher in the field of computational linguistics in the University of Toronto’s computer science department. Computational linguistics involves the use of computer algorithms to analyze aspects of speech such as sentence structure, parsing and word frequency, with the knowledge that speech is an indicator of cognitive health.

Team Warbler awarded grant from Dominion Foundation

April 25, 2017

VCU’s Team Warbler, led by Dr. Catherine Viverette, Center for Environmental Studies (CES), Dr. Lesley Bulluck, CES and Department of Biology, and Dr. Ed Crawford, CES and the VCU Rice Rivers Center, is one of the recipients of this year’s Dominion Foundation environmental stewardship grant.  More than 100 organizations share $1.2 million in funding, with Team Warbler receiving $40,000 towards building a SMARTBirdHouse.

Prothonotary Warblers (PROW) are a migratory bird that has experienced population declines due to habitat loss.  SMARTBirdHouses have the potential to provide ecological and environmental data to track timing or events such as nest initiation, which can be a particularly sensitive indicator of climate change.

In addition, Team Warbler will work with Wyatt Carpenter (M.S. ENVS, 2017) in VCU’s Office of Sustainability to investigate the feasibility of adopting a forest carbon offset program in the Richmond region. Increasing tree canopy can improve local air and water quality while also restoring habitat for migratory birds. 

During the academic year, VCU Engineering students will design and test SMARTBirdHouses using Radio Frequency Identification (RFID) technology which has the potential to track individual birds, record environmental data, capture sounds and images, and transmit data remotely using cell technology. In summer 2017, VCU Environmental Studies and Biology students will deploy RFID tags on PROW at Deep Bottom Park in Henrico County and in 2018 deploy and test SMARTBirdHouse prototypes.

In fall 2017 students in a new Urban Ecosystems course will develop spatial data layers, reports, and assessment tools to model future carbon sequestration through investment in planting trees. In spring 2018 students in Panama Avian Ecology will use the assessment tools to estimate Team Warbler’s carbon footprint, develop a strategic plan to mitigate carbon emissions, and participate in tree planting programs with community partners in Richmond and Panama.

Final products (spatial data layers, reports, assessment tools, DIY instructions for building SMARTBirdHouses) will be made available through a variety of social media platforms.

Assisting with conservation of the Steppe Whimbrel

April 7, 2017

By Fletcher Smith, Center for Conservation Biology  

The Steppe Whimbrel (Numenius phaeopus alboaxillaris) is one of the least studied forms of migratory shorebirds on earth. The form was first described in 1921, and was thought extinct by the mid-1990s. A first “rediscovery” of Steppe Whimbrel was made in 1996 and 1997 on their breeding grounds near the Ural Mountain steppe habitats. No accepted sightings of the form were made on the wintering grounds until the 1950s. If ever a bird population was flying “under the radar,” this was it.  

The recent rediscovery of Steppe Whimbrel made by Gary Allport of BirdLife International was of huge interest to the shorebird conservation community. Finding new species of birds, or rediscovering birds presumed extinct, quite frankly does not happen very often. Gary found a likely candidate for the form within a flock of nominate race Whimbrel (Numenius phaeopus phaeopus), and examination of photographs taken of the bird showed clear indications that one whimbrel in the flock was of the Steppe form. A subsequent second Steppe Whimbrel was found nearby on the same stretch of beach, and both records were well documented.  

You simply cannot help but wonder about the status of this whimbrel. So few records exist of the Steppe form that it is safe to say the population must be low, but what that means exactly is unknown. The population was likely always low compared to the nominate race (N. p. phaeopus) that breeds in the Arctic and sub-Arctic regions of Europe and Russia, and there is evidence for a range contraction and population reduction of the Steppe form. One can only hope that through dedicated conservation and protection that this form will persist and the population will rise, rather than going the way of other Numenius species that winked out and are presumed extinct at this point.

A next step in conservation of the Steppe Whimbrel is to find out where they breed and where they stop in migration. Conservationists also need to know about the breeding population and the breeding range, and the only way to answer large scale questions is through satellite tracking. In February 2017 CCB attempted to capture and deploy a satellite tag on one of the Steppe Whimbrel in Mozambique. We were unsuccessful in tracking the bird, and though the primary goals were not met during the expedition, we are fully committed to assisting in tagging and tracking a Steppe Whimbrel from wintering grounds to breeding grounds next winter. Reports have been trickling in to Gary from other sites in East Africa, and there is reason to believe that more than just a few exist.  

Gary Allport and family were excellent hosts during the expedition, Phil Atkinson of the British Trust for Ornithology helped with all aspects leading up to the capture attempt, and the African Bird Club assisted with logistical support.

Another raptor kill in Argentina

April 6, 2017

By Bryan Watts, Center for Conservation Biology  

José Sarasola has reported another large raptor kill in the La Pampa Province of Argentina.  José is the director of El Centro para el Estudio y Conservacion de las Aves Rapaces en Argentina (CECARA), the primary raptor research and conservation group in Argentina.  CECARA has been monitoring raptor electrocutions in the region for several years.

In July, CECARA found 96 raptors killed along 40 kilometers of electric lines between Chacharramendi and La Reforma.  Surprisingly, the electrocuted birds included 85 black-chested buzzard-eagles.  Their surveys over the next month located an additional 70 electrocuted raptors.  Nearly 95% of the eagles found dead and observed live were juveniles.  Birds appear to have converged on the location from a much larger region and were drawn there by a massive rodent outbreak.      

Black-chested buzzard-eagles are not common breeders in La Pampa but typically nest in the foot hills and mountains.   José believes that the young birds may have dispersed from northern Patagonia or the hills of Córdoba province.  Documentation of this event highlights important conservation concerns.  Hazards such as unprotected electrical lines may cause significant demographic impacts to wildlife.  These hazards may sit idle causing relatively little impact until some trigger such as a rodent outbreak brings a population into contact with them.  Finally, the impact itself may not be local but may be focused on distant populations as is the case here.

Overhead electric lines are a global conservation challenge.  Since the 1970s an international consortium of agencies, corporations, and NGOs has developed simple raptor-safe standards for power lines.  These standards should be used worldwide to reduce avian mortalities.  CECARA continues to investigate the population-level impacts of electric lines on raptor populations in Argentina including the endangered crowned solitary eagle.  

Big Mud

April 6, 2017

Bryan Watts, Center for Conservation Biology  

One day after our arrival in Panama City, we stood on the shoreline looking in awe over the mudflats that stretch out into the blue haze of the Pacific.  As the tide reached its low, the flats extended more than a mile out to the horizon and more than thirty miles down the coast toward Columbia.  We had all worked birds on mudflats.  It was not just the scale of the flats here that was so imposing but the fact that if you stepped off the hard shoreline you could immediately be up to your waist in mud that had the consistently of chocolate pudding.  Standing on the edge conjured up childhood images of the Le Brea Tar Pits trapping saber-toothed cats and short-faced bears to their deaths.  But even on that first day we knew that we would have to venture out onto those flats.

The mudflats here are enriched by both sea and land.  They are bounded on the ocean side by the edge of the shelf that drops off quickly into the deep.  Onshore winds during the winter months create upwellings that bring nutrients from the ocean depth up to the flats.  Rains and tides wash nutrients from the land onto the flats.  Twice a day the tides reach back to the shanties and pull out the leavings of the city.  The debris flows out in a plume that is pushed toward land by the wind and long-shore current, ultimately piling high along the shoreline.  The great garbage dune is a mirror of life in the city.  Anything that floats ends life here unless given a reprieve by shoreline pickers; thousands of dolls lost by school girls, old knick-knacks and discarded figurines, car parts and valuable wood, but mostly plastic drinking bottles.  With the debris is the raw sewage from one million people that flows out into the Bay and mixes with the mud.  There are also tons of leaves from the fringing mangroves that are washed by the tides out onto the flats.  All of these inputs are part of a complex food web that supports the birds that congregate here.

Over the next three months we worked throughout the upper Bay with scores of waterbird species.  We conducted weekly aerial surveys, surveyed miles of transects through non-tidal habitats, and captured, measured, and marked more than 1,000 shorebirds.  We sat along the shoreline and observed how birds used the mudflats.  We recorded the time it took for birds to move out over the flats on a falling tide and how an incoming tide pushed and crowded birds together, causing species with different tactics to abandon foraging and go to roost at different times.  We quantified foraging and movement rates and categorized foraging modes.  We were collecting information that would be used by the United States Department of Defense and State Department to make recommendations to the Panamanian government about the significance of the Panama Canal and surrounding waterways to waterbirds.  The year was 1997 and recommendations were being prepared in advance of the historic transfer of the canal and surrounding lands from the U.S. to Panama.

After three months of working day and night, we had documented many important dimensions of the waterbird community and we had reinforced what we knew the first day.  The spectacle of waterbirds that congregate here all come to exploit an enormous concentration of energy. Here, the mudflats are the provider, the giver of life.  If you want to understand the waterbird community you must confront and address the mudflats directly.  What is hidden in the mud that is so valuable to birds?  Why are some species of shorebirds confined to the edge and never venture out onto the flats?  Why do the mudflat species not move out with the tide line as in most tidal systems?

In early November, we set the date for our mudflat adventure.  As the day approached we all went to the market on Avenida Central to buy high-topped tennis shoes in the hope that they would outlast the mud.  Our plan was to follow the tide out and collect sets of benthic cores every fifty meters out to three hundred meters.  We would place the samples in coded zip-lock bags and pull them in crates across the mud on flat boards like sleds.  We would move out with the tide because we knew that we had a limited window and did not want to be caught out in the mud as the eighteen-foot tide roared back in to shore.

We arrived before high tide in shorts and high tops and began to prepare the field gear.  Alberto Castillo, our local technician, emerged from his truck dressed in yellow rain pants duct tapped around the ankles.  After our visit to the shoe store he had returned to the market with a plan.  Alberto had been sheepish about venturing into the mud from the first time it was mentioned.  He had lived his entire life here along the Bay but had never been on the flats. He said that he did not want to get the mud on his skin.  As we prepared the gear he seemed thrilled with the improvised solution to his dilemma.

We stood ready along the shoreline in teams of two as the tide turned.  Its retreat is like a metronome, slow and steady.  We followed.  Alberto was with me and within thirty meters his well-crafted plan began to fall apart.  The intense suction of the mud shredded and stripped the rain pants leaving him to get the full experience of the mud in his undies for the next two hours.  There are few things that focus the mind and free the soul like being all in on a new adventure.  We collected the fifty-meter samples and when we reached the one hundred-meter sampling station we paused to let the tide move out ahead.

Over the next ten minutes, we would begin to understand some of the patterns we had observed sitting along the shoreline.  The mud surface around us was covered with a silky sheen.  We had observed the sheen for weeks and knew that the birds shunned it.  What we could not tell was that the silky texture was just the surface of a wet, soupy layer that was several inches thick.  Birds could not stand in this layer.  As the tide continued to recede, this layer would collapse down to the more firm surface of the mud and lose the silky sheen.  As this happened, shorebirds appeared in waves all around us.  They moved across the surface and foraged within feet of us as if we were lifeless dolls stranded in the mud.

Being embedded within the mud with shorebirds probing around our field gear was like being set down in a different world.  We were only meters from the shoreline where we had sat for weeks looking out but the experience was wholly different.  The odd contrast of the world class mudflats juxtaposed with the skyscrapers of Panama City was not just visual.  The bustling city with all of its traffic jams, shopping areas, restaurants, and nightlife was a world away.  We could just as easily have been standing in the middle of the Sahara.  Here, birds and people exist in different dimensions.  Standing out on the flats was like being given the opportunity to gaze through a window from the other side.  

We have returned to the Upper Bay of Panama several times over the years to study waterbirds and Panama Audubon now has a program focused on the conservation of shorebirds using the flats.  There are many things that can be learned while sitting along the shoreline.  But there is something about seeing the world through the eyes of another species if only for a passing moment that goes a long way toward framing the questions worth pursuing.

Eagle photographers contribute to science

April 5, 2017

By Bryan Watts, Center for Conservation Biology  

In addition to supporting a thriving population of bald eagles, the Chesapeake Bay is fortunate to have a talented community of photographers who enjoy getting out in the field, experiencing wildlife in a responsible manner, and recording these experiences in spectacular images.  Photographers are increasingly coming into contact with eagles marked with field-readable bands and sharing their images with CCB researchers.  These encounters with known individuals are contributing to what we know about eagle life history.

Beginning in 2007, CCB began banding bald eagles within the Chesapeake Bay population with purple bands that included unique alpha-numeric characters.  Unlike basic USGS aluminum bands (used for decades in the Bay) with long number codes that may only be read in the hand, these characters may be read with spotting scopes or with high-resolution images.  Since 2007, CCB has used these bands on more than 260 eagles.  Many of these birds have been resighted or photographed by the public across multiple states.  However, the three eagle photography hotspots in the Chesapeake include Conowingo Dam on the lower Susquehanna River, Belmont and Pohick Bays on the upper Potomac near Washington, D.C., and the lower Tidewater cities of Norfolk, Virginia Beach, and Chesapeake.

Encounters between photographers and banded eagles are being used by CCB biologists to estimate vital demographic rates, to track dispersal and movement patterns, and to describe changes in plumage over time.  Encounters are particularly valuable for estimating survivorship, a parameter for which information is difficult to collect and critical to understanding the population.  Toward this end, essential information to collect during an encounter includes date, location, and bird identification. 

We very much appreciate the generosity of photographers in sending photographs.  If you have taken images of a marked eagle, please consider sharing so that the encounter may be added to our growing database.  Contact info@ccbbirds.org.

The Universe within, how our microbes shape our health

January 23, 2017

By Elizabeth Ferris, Richmond Magazine

When Jennifer Fettweis stepped on the stage at The Byrd Theatre for a TEDxRVA talk in October, she had news that may have left some in the sold-out crowd squirming. 

The message? You’re not entirely human.

Rather, our bodies are host to a complex network of bacteria, fungi and viruses — trillions of them. These micro-organisms and their products, which are known as the human microbiome, play an important part in bodily functions, from digesting food to warding off infection. Researchers say they may also hold the key to better understanding many diseases.

Research into these microbes and their impact on our health has exploded in the last decade. While traditionally the study of microbes has considered their role as pathogens — disease promoting organisms — the focus of this new research is more holistic.

People and shorebirds flock to beaches

March 29, 2017

By Bryan Watts, Center for Conservation Biology

Let’s face it, people love to spend time on sandy beaches.  We love the combination of sun, sand, and water.  In the United States, travel and tourism is the nation’s largest industry, employer and foreign revenue earner, and beaches are the leading tourist destination.  Each year 180 million Americans make 2 billion visits to beaches – more than twice as many as to all national and state parklands combined.  The revenue generated by these visits is greater than the combined export value of agricultural grains, aircraft, computers, and telecommunications equipment.  The revenue supports one in every ten jobs in the country and represents the economic foundation of many coastal communities.    

Several species of migratory shorebirds depend on beaches for a portion of their annual cycle.  For some, beaches along the Atlantic Coast represent terminal refueling sites where shorebirds must forage to build up the energy reserves needed to make their final flight to arctic breeding grounds.  Many of these species are sensitive to human disturbance.  Human activities may force them from beaches to less profitable foraging areas, may alter their foraging behavior or foraging times and ultimately reduce food intake and energy storage.  For some species, human and shorebird use of beaches is not compatible.  Our love and use of the beach effectively renders extensive swaths of the coastline off-limits to some shorebird species.

Beaches along the south Atlantic Coast of North America are critical to both the regional economy and to migratory shorebirds.  How to accommodate these two important user groups is one of the great conservation challenges faced by coastal land managers.  During the springs of 2011 and 2012, CCB conducted aerial surveys of the entire coast of North Carolina to evaluate the interrelationship between human use of beaches, beach ownership, and shorebird distribution during the spring staging period.  A paper focusing on the federally threatened red knot titled “The influence of land ownership on the density of people and staging red knot on the coast of North Carolina” is being published in the journal Wader Study.  North Carolina is particularly well suited for this investigation because in recent decades the outer coast has reached “terminal build out,” where more than 98% of the coastline is either privately owned and developed or owned by government agencies focused on natural resources.  There is virtually no remaining opportunity for conservation acquisition. 

Land ownership had a dramatic influence of the distribution of both red knots and people.  Average knot density was more than four-fold higher on government compared to privately-owned lands.  Conversely, human density along the shoreline was more than ten-fold higher on private lands compared to government lands.  Along the coast of North Carolina, private lands include resort hotels that support extreme human densities and residential developments that support permanent residents or vacation rentals.  More than 80% of knots surveyed occurred on shoreline segments that supported less than five people per kilometer of shoreline.  These conditions were most frequently found on government lands with active beach closures.  Migrant red knots appear to benefit from beach closures imposed to protect nesting piping plovers and sea turtles.

For coastal landscapes that have reached terminal build out, some of the best opportunities for red knot conservation revolves around managing human behavior and access to critical sites on government-owned lands.  This may include seasonal closures of the most critical sites, limiting the number of access points to less critical sites and providing education system-wide to change human behavior during critical times of the year.  A great challenge will be to strike an appropriate balance between access that may be important for local economies and restrictions that are essential to shorebird conservation.   

Getting their feet wet

March 27, 2017

By Virginia Commonwealth University

As their classmates listen for the bell to ring at Armstrong High School, one group of students is listening instead to the gentle flow of water in Kimages Creek in rural Charles City County.

They are visiting this bucolic scene to learn more about water use and pollution in the concrete environs of Richmond, and what impact pollution has flowing down the James River and into the Chesapeake Bay.

The students, enrolled in VCU alumna Lauren Kern’s biology class, are partners in the Community Greening Project, which studies storm-water runoff issues in Richmond neighborhoods. They are developing an online multimedia map where community members can log problem areas, and are hosting community meetings to gather input and suggestions.

“In the classroom, students learned how their actions could impact urban runoff, which flows into the James River and makes its way south, to the Rice Rivers Center,” said Jennifer Ciminelli, research and data coordinator for the center and faculty in VCU’s Center for Environmental Studies.

Bridge Birds

March 21, 2017

 

By Bryan Watts, Center for Conservation Biology

Bridges often occupy a dominant position on the landscape overlooking extensive areas of open water or land.  Due to their height and exposure they receive nearly constant winds.  In many ways they mimic the conditions that attract nesting peregrines to coastal cliff sites throughout much of the world.  In coastal Virginia where cliff formations are completely lacking, bridges have played a significant role in the recovery of the breeding population.

Since 1993, bridges have consistently supported more than 30% (ranging up to as high as 50%) of the known breeding population of peregrine falcons in Virginia.  The association began in the early spring of 1988 when a single peregrine was resident on the Coleman Bridge across the York River.  Between 1988 and 2016, peregrines have been documented to use 15 different bridges including five that have been used for 18 years or more.  During the 2016 breeding season, peregrines nested on 11 bridges.  

Supporting breeding peregrines on bridge structures has not been a completely benign relationship. Peregrines are protected by seasonal and spatial restrictions designed to improve breeding success.  Restrictions have increased operational costs for bridges and caused concerns for bridge management and maintenance planning.   Risks may be mitigated by knowing the occupancy status of a bridge in advance of bridge maintenance projects and by managing nesting birds away from operational areas or areas that require regular maintenance.  Managing peregrine falcons on bridge structures has been a collaborative effort between the Virginia Department of Game & Inland Fisheries, The Center for Conservation Biology, and the Virginia Department of Transportation.  

During the 2016 breeding season CCB biologists, in collaboration with the Virginia Center for Transportation Innovation and Research and the Virginia Department of Transportation, surveyed 83 bridges in coastal Virginia for occupancy by peregrine falcons (download report).  The primary objective of the project was to determine bridge occupancy that would reduce uncertainty in planning operations and maintenance activities.  Additional objectives included the testing of a rapid survey protocol that may be used in future bridge surveys, the identification of bridge characteristics that attract falcon pairs that may be used in identifying bridges with high potential for colonization in the future, and a retrospective study of the effectiveness of falcon management techniques that have been and continue to be used on bridges in Virginia.  

Eleven of the 83 bridges were determined to be used by peregrines in 2016, including two bridges that were previously unknown to support pairs.  Response of birds to the taped calls used to survey bridges was dramatic with a more than 90% response rate by known pairs.  Most birds responded to tapes immediately with 60% responding within 5 seconds and 80% responding within 10 seconds of tape initiation.  Territorial birds called repeatedly and often circled around the tape.  Occupied bridges were longer, embedded within more open landscapes, and had more potential nest sites compared to bridges that were not occupied.  Lift or draw bridges were particularly sought after by peregrines, with eight of ten available moveable bridges being used for nesting over the past ten years.  These bridge types have the highest availability of potential nest sites with overhead structures allowing peregrines to nest with protection from the weather.

One of the most satisfying findings of the retrospective investigation of peregrine management techniques used on Virginia bridges is how effectively they have improved breeding performance.  When breeding performance is compared before and after nest boxes or trays were installed on bridges, peregrine pairs were more than twice as successful while using boxes, and successful pairs produced more than twice the number of young.  The often overlooked benefit of using boxes to manage pairs is that they may frequently be used to entice pairs away from areas of the bridge that require regular maintenance.  One of the clear conclusions of the study is that active pair management is beneficial to both the birds and to bridge operations.

Chesterfield County's Cosby High School introduces oysters into classroom

February 9, 2017

By Sarah Vogelsong, The Progress-Index

CHESTERFIELD - Even good vibrations can cause an oyster to clam up.

As students move around Anthony Palombella's biology classroom at Cosby High School in Midlothian, carrying out experiments and talking scientific shop, the nine oysters that inhabit a simple rectangular tank on the room's edge sense their presence through sound waves and go still.

It's only when the vibrations diminish that the creatures feel secure enough to open the protective lips of their shell to feed and, in so doing, filter the surrounding water.

This scientific observation - one that reveals much about the role and behavior of this prized bivalve within Virginia's rivers and coastal waters - is just one of many that Palombella's students have made this year as part of Chesterfield County Public Schools' collaboration with the Virginia Oyster Shell Recycling Program.

New Director of Center for Environmental Studies named

February 1, 2017

Dr. Robert M. Tombes, Vice Provost for Life Sciences and Research at Virginia Commonwealth University, recently announced Dr. Rodney Dyer as director of the Center for Environmental Studies (CES). Dr. Dyer held the position of assistant director of the Center for Environmental Studies for the past two years, and has been a member of the VCU faculty since he began in 2004 as assistant professor in Biology.

Dr. Dyer’s vision for CES is to produce quantitatively skilled practitioners of environmental sciences.  Approximately 70 CES students graduate annually, with graduates enjoying one of the highest rates of job-related placements.

 “Dr. Dyer is a world-renowned quantitative population geneticist whose creative teaching and scholarship are pioneering and perfectly aligned with the integrative nature of CES and Life Sciences,” stated Dr. Tombes.  “I am grateful for the groundwork laid by his predecessor, Dr. Greg Garman, who will now focus on the growth of research at our field station, the Rice Rivers Center.” 

A botanist by training, Dr. Dyer’s research focuses on population genetics and the impact that intervening landscape features have on genetic connectivity.  He has mentored 11 graduate students in Masters programs in CES and Biology, and the Integrative Life Sciences doctoral program.  The vast majority of that graduate work has been conducted at the Rice Rivers Center.

Dr. Dyer continues his phylogeographic work in Baja California, examining how coevolving plant and insect systems respond after climatic changes following the Pleistocene. This project is funded by the National Science Foundation (NSF). He also has received NSF funding to study terrestrial genetic connectivity along urban gradients from Richmond, Virginia, to Rice Rivers Center in Charles City, Virginia, using flowering dogwood as a model system.  Dr. Dyer is a strong believer in Open Source research and publishing; his authored textbooks, “Landscape Genetic Data Analysis” and “Applied Population Genetics,” are both available without charge at his website, dyerlab.com.

Dominion Foundation gift helps support environmental sciences training

January 17, 2017

A new “enviro-techniques” class will use the VCU Rice Rivers Center as an outdoor laboratory for environmental sciences research training, thanks to the generosity of a $50,000 gift from the Dominion Foundation to VCU Life Sciences. The two-course series for undergraduate and graduate environmental science and biology students will use modern research tools to quantify carbon sequestration and greenhouse gas emissions in wetlands and forests, and evaluate the connection between plant and animal biodiversity.  The first three-week session will take place this summer.

The course is being developed and directed by Ellen Stuart-Haentjens, M.S., with Scott Neubaurer, Ph.D., and Chris Gough, Ph.D., participating in training module development and co-instruction. The program will become a permanent offering in the university’s Environmental Studies and Biology curriculum.  Once completed, course materials will be made available to the VCU community and public via open access.

Financial support from the Dominion Foundation will provide essential equipment and supplies, including software for real-time data analysis and visualization, measurements of tide, greenhouse gas-trapping chambers, and field laptops and tablets. Additional support from the Dominion Foundation provides a cohort of student researchers with supplies to conduct independent research projects after the completion of the enviro-techniques course.  Students will be challenged to formulate hypotheses, execute research activities, and analyze data onsite at Rice Rivers Center.

“The breadth of ecosystems and state-of-the-art instrumentation at the VCU Rice Rivers Center make for a perfect outdoor classroom,” stated Dr. Chris Gough. “We are uniquely positioned to teach and assist students in the development of skill sets they can apply to their research and careers.”

The second part of the series will have students return to Rice Rivers Center and collaborate in teams to address real-world environmental science questions by use of critical thinking, team work and instrumentation.

Following the historic and successful move of eight red-cockaded woodpeckers into the Great Dismal Swamp during the fall of 2015, the multi-state and multi-agency coalition gathered again in October 2016 to execute the second of a scheduled three-year commitment to move woodpeckers.  The effort was successful despite the wrath of the weather gods.

The Great Dismal Swamp, the northernmost of the great humid swamp forests of the South, received more than 20 inches of rain in the run up to the 2016 move.  In late September, Tropical Storm Julia moved north along the Atlantic Coast and stalled over Hampton Roads, dumping more than 12 inches of rain on the swamp.  Just one month later Hurricane Matthew, one of the most destructive hurricanes in recent memory, made its way up the coast dropping another 12 inches of rain on the swamp.  Slow to drain, the swamp held a tremendous amount of water in the week before the scheduled woodpecker move, with many of the trails requiring waders to slosh through.  In addition to the standing water, there was just enough time following the rains to create a dramatic hatch of mosquitoes throughout the swamp.

After much deliberation about the post-storm conditions, Will McDearman, National Recovery Coordinator, and Nancy Jordan, maestro of the Carolina Sandhills woodpeckers, decided in true field biologist fashion to move forward and “get ‘er done.”  This decision triggered a convergence of woodpecker biologists on Carolina Sandhills National Wildlife Refuge from throughout the Southeast on 18 October to “roost” targeted birds.  Roosting went as planned and the decision was made to capture and transport birds on the 19th.  Four hatching-year males and four females were captured, boxed, and transported north on the evening of the 19th.  The drive north was longer than usual due to road closures and detours related to Hurricane Matthew, but all birds arrived and were placed in artificial cavities for release by 4:30 AM.  Screens were removed and birds were released into their new habitats at 7:00 AM.  

A second translocation was conducted during the fall in order to even out the sex ratio and to give the population the maximum likelihood of forming new breeding pairs.  On 14 November, a Virginia crew traveled to Carolina Sandhills National Wildlife Refuge and roosted, captured, and transported two hatching-year males for release in the swamp.  The transport and release went off without any problems and both birds were released the next morning.  With the successful conclusion of the second translocation of 2016, the refuge held seven males and eight females.  A survey will be conducted in early spring of this year to determine retention of birds and follow-up breeding monitoring will be conducted in late April and May.

OspreyWatch Anniversary

January 13, 2017

By Bryan Watts, Center for Conservation Biology

In 2012, The Center for Conservation Biology launched OspreyWatch, an online global community making observations of breeding osprey.  The intent on a local scale was to connect people to the breeding pairs around them, to have them engage in the daily lives of these birds, and to learn more about their breeding ecology.  Observers have included school groups, master naturalist chapters, bird clubs, and homeowners.  The intent was to harness the power of many observers to collectively examine large-scale patterns of breeding phenology and productivity.  The osprey is an ideal sentinel species of aquatic ecosystems.

The 2016 breeding season is the fifth since the establishment of OspreyWatch and we have been overwhelmed by the response and generosity of observers.  More than 5,600 nests have been registered across several countries with most of the activity concentrated in North America.  Nearly 3,000 full-season nesting accounts have been entered.  All of these efforts are making a contribution to what we know about ecology across the breeding range.

Among other findings, the data submitted has highlighted the latitudinal shift in nesting date.  The onset of incubation shifts more than 150 days (nearly 5 months) across 30 degrees in latitude.  The most dramatic shift occurs from the resident population in south Florida, which has the earliest breeding season in North America, to the migratory populations in Georgia and South Carolina.  Over a span of only 10 degrees north, the onset of incubation shifts nearly 100 days.  North of South Carolina, the rate in the delay in nesting declines to 2.5 days per degree in latitude compared to 10 days per degree south of North Carolina.  This important data serves as a benchmark for comparison of future patterns as the climate continues to warm.

Tracking eagles in 3D

January 13, 2017

By Bryan Watts, Center for Conservation Biology

Aviation safety depends on knowing the location of hazards within the airspace.  A great deal of time and effort has been spent to carefully map and mark stationary hazards such as tall buildings, towers, and mountains to inform pilots about their location and height.  But all hazards are not stationary.  Birds are one of the most significant categories of non-stationary hazards within the airspace and represent a potential hazard to aviation.  One of the most dramatic events in recent years that brought public attention to this problem was when flight 1549 ingested Canada geese in both engines just after takeoff on 15 January, 2009 and was forced to make an emergency landing on the Hudson River.  

Globally, wildlife strikes have killed more than 262 people and destroyed over 247 aircraft since 1988.  Factors that contribute to the increasing threat are the increasing populations of large birds and increased air traffic by quieter, turbo-powered aircraft.  In the United States, strikes have increased nearly 7.5 fold since 1990, reaching 13,795 in 2015.  During that year the estimated cost was nearly 70,000 hours of aircraft downtime and $229 million in equipment and operational costs.  Birds were involved in 98.5% of strikes and in terms of damage and risk, size matters.  For every 100-gram increase in body mass there is a 1.3% increase in the likelihood of aircraft damage if a strike occurs.  In eastern North America bald eagles, various species of geese and swans, and large gulls represent some of the greatest threats.    

More than 70% of bird strikes occur below 500 feet and most happen around airports during takeoff or landing.  As with the incident on the Hudson, because strike risk is highest during low-altitude flights around airports, understanding the spatial patterns of bird distribution and movement in the vicinity of runways is a high priority to improve aviation safety.  Due to their large body size and the tremendous increase in their population within the Chesapeake Bay, bald eagles represent a growing concern to airport operators.  Understanding their distribution and movement patterns around runways may help to inform pilots of potential hazards and contribute to flight planning.

During the spring of 2016, CCB assisted the U.S. Department of Defense to deploy 12 transmitters on bald eagles near airports.  The Microwave, Inc. transmitters used provide a very high data rate and were programmed to deliver altitude.  The accumulation of bird movements and positions over time has revealed areas that are consistently used by eagles, as well as the vertical distribution of activity associated with the sites.  Mapping these bird hazard sites is similar to mapping fixed hazards like towers, with altitudes to avoid.  The information will hopefully be helpful in planning flight operations around the airfields.

Master's student studies at the Cary Institute

January 12, 2017

Spencer Tassone is one of a handful of students from across the globe awarded an opportunity to study at the prestigious Cary Institute of Ecosystem Studies in Millbrook, New York.  The course is taught by some of today’s top ecosystem ecologists during the winter intersession, January 3 – 13, 2017.

 A large part of foundational work for Tassone’s master’s thesis in Biology – examining what proportion of ecosystem metabolism is made up by pelagic metabolism and how the abundances of the dominant zooplankton species in the tidal freshwater segment of the James River respond to changes in primary production – has been built on or conducted by ecologists at the Cary Institute.  The course will expose Tassone to the latest research areas in ecosystem ecology, allowing him to identify key areas of interest as he develops a Ph.D. thesis project.

The VCU Rice Rivers Center provides Tassone invaluable resources towards his thesis research, including continuous water quality monitoring of the James River from the Rice Rivers Center’s pier, and data from the weekly water quality monitoring program.

“The Rice Rivers Center has been transformative in my education and research career,” says Tassone.  “I would not be where I am today without it.”

Plovers navigate the dangers of Hurricane Matthew

January 11, 2017

By Fletcher Smith, Center for Conservation Biology

For over a century, people have wondered what exactly happens when birds encounter hurricanes.  Even into recent decades, the behaviors of birds in hurricanes were purely speculative, or based on few direct observations.  Resident breeding birds along the Atlantic Coast have adapted to periodic hurricane events, though even localized storm damage can impact populations of some bird species.  The impact of large storms on barrier island or beach systems isn’t always negative, and some birds (piping and snowy plovers, for instance) have adapted to nesting in the overwash areas created by cyclones, nor’easters, and other large storm events.  Migratory birds have a different relationship with hurricanes, with the probability of encountering a storm overlapping with only a small window of time of their annual cycle.  Though the odds are unlikely, the chance encounters have drastic implications for smaller land birds that face a storm over the open ocean, and many passerines likely perish within the winds of large tropical systems.  Pelagic birds can ride the winds and find themselves inland, hundreds or even thousands of miles away from typical open-ocean locations.  Some birds find themselves “stuck” in the center of storms unable to break through the wall of wind to reach safety.       

Until recent years, it was generally an accepted theory that most birds that migrated into large hurricanes over the open Atlantic perished.  Through the amazing remote tracking technologies available to scientists, we now know that at least some types of birds are able to navigate directly through these storms and beyond.  Remotely tracking a migratory bird into a Category 3 hurricane and seeing the bird safely make it through the other side of the storm has the power to captivate anyone.          

With all of this in mind, we watched in near-real time as six black-bellied plovers settled into their migratory stopover sites or wintering locations in Jamaica, Cuba, Florida, Georgia, and South Carolina, just as Hurricane Matthew picked up intensity and made towards the region in early October 2016. All of these plovers were tagged in the High Arctic breeding grounds in 2015 and 2016.     

Amazingly, all of these birds made it through the storm, and we were able to look at the strategies the birds used to avoid the worst of the storms as the hurricane strafed the region.  When we zoom in on the plover in Florida, we can see the bird move from the marshes and beaches of New Smyrna to the nearby airport, a likely refuge from the storm surge that Matthew brought with the winds.  This plover appears to have set up shop in the airport now and may continue there through the winter.

The technological breakthroughs in tracking birds have given the scientific community the ability to see behaviors and migrations with incredible detail.  With each breakthrough in the reduction of size and weight of transmitters, more bird species become available to track.  The deployment of transmitters on black-bellied plovers is a collaborative effort between Canadian Wildlife Service (CWS) and The Center for Conservation Biology, and was initiated by CWS in 2014.  The goal of the tracking study is to understand the connectivity of arctic nesting shorebirds to stopover sites and wintering grounds.  Understanding the linkages of the plovers and other shorebirds is critical to the conservation of these birds along the flyway.  The tracking of the plovers is an ongoing project and they can be followed at Wildlifetracking.org.

Breeding birds of Virginia

January 11, 2017

By Bryan Watts, Center for Conservation Biology

On 21 May, 2015 the Virginia Academy of Science held a symposium on the campus of James Madison University entitled “State of Virginia’s Environment.”  The full-day symposium included sessions on all taxonomic groups, as well as many prominent habitats, geology, water quality, and land use.  The meeting provided the opportunity for scientists to gather and discuss current conditions.  A forthcoming symposium volume will be available to provide an enduring benchmark.  For the various taxa included, the symposium represents the fourth in a series of benchmarks since the late 1970s that have offered historical “point-in-time” treatments.  The updated treatment of Virginia’s breeding avifauna produced by Bryan Watts (download available) provides 1) a historical context of information on breeding birds in the state, 2) an update on recent status assessments, and 3) a retrospective analysis of breeding birds of conservation concern.   

The ornithological record in Virginia stretches back more than four centuries.  From the time of settlement at Jamestown in 1607, residents of Virginia and visitors to the state reported on the birds they encountered or were told about by Native Americans.  William Strachey, Captain John Smith, Raphe Hamor, Edward Topsell, George Percy, and John Clayton, Vicar of Crofton reported on birds they observed during the 1600s including immense flocks of passenger pigeons and Carolina parakeets.  As time passed, early local accounts began to coalesce and were compiled into growing lists that began to provide a more complete assessment of the avifauna within the state.  Thomas Jefferson gave an early list of 125 bird species for the “Virginias.”  These early treatments led to two significant works that gave a more complete assessment of the breeding birds including William Cabell Rives’ “A catalogue of the birds of the Virginias” and Harold Bailey’s “The Birds of Virginia.”  Throughout the early 1900s, a community of bird enthusiasts including academics and citizen volunteers formed, eventually leading to the establishment of the Virginia Society of Ornithology in 1929.  One of the stated missions of the organization was “to gather and assemble data on the birds of Virginia.”  The long period of “ornithological exploration” in Virginia would eventually come to a close with Murray’s production of “A check-list of the birds of Virginia” in 1952.  This benchmark work would be updated in 1979, 1987, and 2007.  Incredibly, virtually all of the breeding species that have been added to the avifauna since Murray’s initial checklist have been the result of range expansions into the state rather than new discoveries of long-existing species.

Virginia supports an impressively diverse community of breeding birds.  This diversity reflects the latitudinal position of the state and the fact that the border extends from the Atlantic Ocean to the Appalachian Mountains.  A total of 224 species have been recorded breeding in Virginia, 214 of which are extant. Twenty species have colonized the state since 1900, including 14 since 1950.  Of all extant species, 102 (48%) are considered common at least somewhere in the state and 64 (30%) are rare to very rare.  Diversity varies by physiographic region with 179 (83%), 168 (78%), and 141 (66%) in the Coastal Plain, Mountains, and Piedmont respectively.  Two major landscape features make significant contributions to the state-wide diversity, including tidal waters along the coast and isolated spruce-fir forests of the Appalachians that represent Pleistocene-era relicts.  In all, nearly 25% of the state-wide avifauna is either wholly or nearly confined to tidal water and 10% is confined to “sky island” refugia.

Since 1978, 25 species of birds throughout Virginia have been identified as requiring immediate conservation action.  A retrospective assessment shows that five of these species including osprey, bald eagle, peregrine falcon, brown pelican, and piping plover have recovered to or beyond historic numbers.  Three species including Bewick’s wren, Bachman’s sparrow, and upland sandpiper have been lost from the state, and the black rail, loggerhead shrike, and Henslow’s sparrow are in imminent danger of extirpation.  Several species including the peregrine falcon, piping plover, Wilson’s plover, and red-cockaded woodpecker are the focus of intensive monitoring and management programs. 

Breeding bird populations in Virginia are dynamic.  Many have changed in size and distribution over recorded time along with shifts in habitats and other factors both within and beyond the state’s borders.  The ever-changing nature of these populations and the underlying causes are what make bird study in the region so challenging and exciting.  

Virginia peregrine falcons leap forward

January 5, 2017

By Bryan Watts, Center for Conservation Biology

Virginia supported 31 pairs of peregrine falcons during the 2016 breeding season (download 2016 report).  With a historic pre-DDT population estimated to be 25 breeding pairs, the 2016 population is the largest ever recorded in the state and represents the fourth consecutive year exceeding the historic mark.  As with all years since reintroduction efforts began in the late 1970s, birds were concentrated on the coast including 28 pairs on the Coastal Plain, 1 pair in the Piedmont, and 2 pairs in the mountains.  The dramatic success story is dampened only by the lack of recovery in the mountains.  Virtually the entire historic population nested on open cliff faces in the mountains.  The two pairs currently known from this region represent a recovery of less than 10%.

Despite the record number of pairs, 2016 was a difficult breeding season for peregrines and many other species.  The relentless rains during the heart of the breeding season appeared to have an impact on productivity.  Only 49 of 85 (57%) eggs hatched and several pairs made very late breeding attempts.  Productivity (1.58 young/pair) was considerably lower than observed in recent years. 

Efforts continued in 2016 to identify breeding adults using field-readable bands to better understand dispersal and demography throughout the mid-Atlantic region.  The banding status of 45 of the 63 (71%) adult peregrines known within the breeding population was determined.  Twelve (26%) of the 45 birds were unbanded.  Among the banded birds where state of origin could be determined, 20 were from Virginia, 6 were from New Jersey, and 2 were from Maryland.  Birds ranged in age from 1 to 16 years.  In addition to adults breeding in Virginia, bands for 12 additional falcons were read and reported over the past year.  Six of these birds originated in Virginia and were found breeding in other states including a male and female in Pennsylvania and four females in New Jersey.

The Virginia population continues to benefit from a tremendous community of dedicated agencies, corporations, and individuals including the Virginia Department of Game & Inland Fisheries, the Virginia Department of Transportation, the U.S. Fish and Wildlife Service, the National Park Service, the U.S. Forest Service, the U.S. Coast Guard, the U.S. Department of Defense, Dominion, and The Nature Conservancy.

Eastern black rails in free fall

January 5, 2017

By Bryan Watts, Center for Conservation Biology

The black rail is the most secretive of the secretive marsh birds and one of the least understood species in North America.  Referred to by Alexander Sprunt as a “feathered mouse,” black rails rarely venture out from the rankest vegetation available.  Because of their extremely secretive habits, the species was not recognized by the ornithological community as occurring in North America until Dr. Thomas Rowan captured an adult male with four young on 22 July, 1836 on his farm in Philadelphia and brought them live to Titian Peale.  Later that fall, Peale would send the specimens to Audubon and they would be the basis of his plate on the species and a declaration of their occurrence on the continent.  As additional specimens and observations were collected, a rough outline of their distribution would slowly unfold over the next century.  Even today, what we know about this little rail is scattered in bits and pieces throughout more than 150 years of literature, museum specimens, and unpublished observations.  One of the recurring themes echoed from the time of their initial discovery to the present is how frustratingly little we know about their distribution and ecology.

Concern for the eastern black rail population in North America began to build in the late 1980s and early 1990s, eventually leading to the formation in 2009 of the Eastern Black Rail Conservation and Management Working Group that has successfully brought biologists and agencies together around a common goal of collecting and sharing information for the purpose of developing a conservation strategy.  Since the establishment of this group, targeted surveys (2014-2018) have been initiated on an unprecedented scale including new work in New Jersey, Maryland, Virginia, North Carolina, South Carolina, Georgia, Florida, and Texas.  A high priority activity identified by the working group has been to locate, collect, and compile all information pertaining to the population with the intention of developing the historical context needed to inform conservation efforts moving forward.  The Center for Conservation Biology completed this assessment in October of 2016.  The treatment includes all states along the Atlantic and Gulf Coasts (view report). 

The historic breeding range of the eastern black rail appears to have included coastal areas from south Texas north to the Newbury Marshes of Massachusetts and interior areas west to the eastern slope of the Appalachian Mountains.  Credible evidence of occurrence was found for 21 of the 23 states, including 174 counties, parishes, and independent cities and 308 named properties.  Many of the named properties are well-known conservation lands including 46 national wildlife refuges, 44 state wildlife management areas, 26 state and municipal parks, and many named lands managed by non-governmental conservation organizations. 

Black rails within northern areas have experienced a catastrophic decline including a contraction of the northern range limit from Massachusetts to New Jersey, a distance of 450 kilometers.  Study areas in New Jersey, Delaware, Maryland, and North Carolina that were surveyed in the late 1980s and early 1990s and again over the past two years have documented a 64% decline in occupancy and an 89% decline in birds detected equating to a 9.2% annual rate of decline.  Maryland has experienced a 13.8% annual rate of decline.  South Carolina has experienced a 4.7% rate of decline for the same period.  No information is available to assess trends for areas south of South Carolina.

In addition to these broad-scale declines, one of the more disconcerting discoveries has been the virtual loss of the species from global strongholds.  Elliott Island in Maryland has the distinction of representing the largest concentration of black rails ever documented when on 2 June, 1954, Terborgh and Knudson reported more than 100 calling birds.  The site would attract bird watchers and biologists for the following 60 years.  Counts have declined consistently and since 2010 peak counts have been one calling bird.  In 2016 no birds were heard from Elliott Island.  A similar pattern has been documented from Saxis Marsh, the historic stronghold in Virginia, where birds have not been detected since the summer of 2014.  On Cedar Island in North Carolina where Rowlette and Wierenga recorded more than 80 calling birds on 27 May, 1973 only 4 calling birds were recorded in 2014.

The eastern black rail is listed as endangered in six eastern states and is a candidate for federal listing.  The eastern working group has been actively pushing to fill information gaps throughout the range, to establish benchmarks, and to identify possible factors contributing to declines.  The working group held a symposium during the Waterbird Society meeting in New Bern on 23 September that included six papers on recent findings from biologists working throughout the range.

Oysters in the classroom

December 8, 2016

The Virginia Oyster Shell Recycling Program (VOSRP) was recently awarded a grant from the Dominion Foundation to implement a detailed curriculum to raise awareness of the biological, social, economic and ecosystem benefits provided by oysters in two area high school classrooms.  The project includes the placement of oyster reef tanks in the class, as part of the curriculum.

The project is a collaboration between our VORSP, the Math Science Innovation Center (MSiC) in Richmond, Chesterfield County Public Schools (Cosby High School), Richmond Public Schools (Armstrong High School) and VCU Center for Environmental Studies students.

The curriculum includes designed classroom activities which meets the requirements under the Virginia Standards of Learning (SOL). Students are able to explore the physiological and ecological processes of oysters and oyster reefs that help create healthy and thriving bays, and the cascading positive effects they can have on an ecosystem.

VCU Life Sciences recently signed a memorandum of agreement with the River Management Society (RMS) that will allow students in Environmental Studies, Biology, and other VCU programs to participate in a River Studies Certificate. RMS is a national nonprofit professional organization whose mission is to support professionals who study, protect, and manage North America's rivers.

Students will complete academic coursework in river science, management, policy, spatial data analysis, and water safety to receive the Certificate. In addition to VCU coursework, students will be encouraged to study at cooperating colleges and universities in Colorado, Idaho, Washington, and other states in the Pacific, Northwest and Southwest region. VCU is the first school on the east coast to become part of the River Studies Certificate collaborative. For more information, contact Dr. James Vonesh (Biology) or Dr. Greg Garman (Environmental Studies).

Dr. Leonard A. Smock retires as director of VCU Rice Rivers Center

December 1, 2016

In 1979, Dr. Leonard A. Smock joined the faculty at Virginia Commonwealth University as an assistant professor in the Department of Biology.  His thought was to stay for a “little while” at VCU; that “little while” spanned 37 ½ years.

Dr. Smock began his journey as a student at the University of Illinois, where he received his bachelor’s and master’s degrees in Biology and Zoology. He continued on to receive his doctoral degree from the Department of Environmental Sciences and Engineering at the University of North Carolina - Chapel Hill. It was then he made his way to Richmond, Virginia, to join the faculty at VCU.

He soon rose to the rank of professor, and served as the Department of Biology’s chairman from 1990 to 2009.  In 2005, Dr. Smock became the first director of the Inger and Walter Rice Center for Environmental Life Sciences, VCU’s environmental field station on the James River in Charles City County. Also known as the Rice Rivers Center, this ecologically rich, approximately 500-acre site provides VCU faculty and students a place to conduct research, education and outreach activities. Dr. Smock served as the director of the Rice Rivers Center until July 1, 2016. Since then, Dr. Smock has remained active at the Rice Rivers Center and plans to stay connected after his official retirement on January 1, 2017.

Looking back on his career, Dr. Smock remarked, “Being a part of the faculty at VCU has been a wonderful experience. I am thankful VCU allowed me to teach the classes that aligned with my interests, and to conduct the research I wished to pursue. I enjoyed interacting with everyone in biology, life sciences and throughout the university.  I look forward to continuing to be involved at the Rice Rivers Center as it grows into a world-class, fully-immersive research facility.” 

Dr. Smock established and was the initial director of the Ph.D. program in Integrative Life Sciences and served as the Interim Vice Provost for VCU Life Sciences and Research.  He was the former president of the North American Benthological Society, the foremost scientific society focused on the ecology and assessment of streams and rivers. In addition, he is a fellow of the American Association for the Advancement of Science and was a council member for the American Institute of Biological Sciences.

First SER@VCU Ecological Restoration Conference at VCU Rice Rivers Center

November 30, 2016

The VCU Chapter of the Society for Ecological Restoration (SER@VCU) hosted the first Ecological Restoration Fall Conference and Workshop on November 12 at VCU Rice Rivers Center. Those who attended were introduced to restoration practitioners from VCU and the Virginia Department of Conservation and Recreation Natural Heritage program.  Participants also were part of laying the groundwork for the first native plant nursery at VCU Rice Rivers Center. 

The SER@VCU chapter was formed in the spring of 2016, when a group of Life Sciences graduate students interested in ecological restoration approached Dr. Ed Crawford to become their faculty mentor.  The Society for Ecological Restoration (SER) is an international organization, with members and partners in over 70 countries. SER@VCU is the first student chapter in Virginia, and one of only three on the East Coast.  The students join a team of researchers and scientists committed to SER’s mission to promote ecological restoration as a means of sustaining the diversity of life on Earth and re-establishing an ecologically healthy relationship between nature and culture.

SER@VCU has attracted significant campus and community interest since its general interest meeting in February 2016.  In March, the first contingent of VCU students ever to participate in a regional SER conference traveled to New Jersey, where undergraduate Christopher Gatens’ poster took first place in the audience choice awards.

The group hopes to make the Fall Conference and Workshop an annual event, and are planning additional workshops both on and off campus this spring. 

Center for Environmental Studies Dr. Rodney Dyer teaches applied analysis workshop in Scotland

November 29, 2016

Dr. Rodney J. Dyer, Assistant Director for VCU’s Center for Environmental Studies, has recently returned from Scotland where he taught a five-day course, Landscape Genetic Data Analysis Using R, at the Scottish Centre for Ecology and the Natural Environment (SCENE).  SCENE is the University of Glasgow’s leading field station. 

The course covered the basis of both quantitative landscape ecology and populations genetics, with a focus on developing and evaluating spatial/genetic analyses using the R platform. Graduate students, postdoctoral researchers, and primary investigators interested in learning how to integrate landscape ecological and population genetics tools using the R software attended the class.  The international group came from countries such as Uruguay, Israel and Croatia. 

SCENE provided a perfect setting, located within Loch Lomond and the Trossachs National Park with on-site buildings for education and research. The rich habitat provides a unique place for teaching, training and research in ecology and environmental sciences.  “This is what we envision Rice Rivers Center to be, as we work towards building the overnight lodge and research facility,” remarked Dyer.

Dyer’s expertise in landscape genetics will take him to China in November 2017, followed by a trip to South America. The problem of landscape conversion has become an urgent concern worldwide, given the tempo and extent of human-mediated disturbance.  “During the next 50 years there will be more urbanization,” states Dyer, “and for long-lived organisms, changes are happening at such a pace that species will not be able to mount adaptive responses.  As a result, we must look to managing genetic variation and diversity now, as it is only going to decline for the vast majority of species around us as we go forward.”

How are Drones Being Used in the Classroom?

November 28, 2016

By Jeremiah Karpowicz, Commercial UAV News 

Understanding how professionals are actually using UAVs is a critical consideration for anyone wanting or trying to properly leverage the technology. What does it actually mean for someone to use a drone in the field? Will utilizing a UAV create efficiencies that can be quantified? How is all of that impacting the bottom line for the project? These are questions professionals want and need to have answered, but the challenges associated with doing so stem from the fact that all of this is new technology. It’s not as if working professionals learned about how they could or should be using the technology when they were in school.

That won’t be the case in the near future though, as various programs and universities are working to integrate drone technology in an active way into what students are learning in the classroom. Doing so isn’t just about using drones though, because the reality is that UAVs will soon be thought of as just another tool. Before that happens professionals will need to have a nuanced understanding around how the technology can be leveraged, and that’s exactly what’s happening in courses at West Point and Virginia Commonwealth University.

Blending science and creative writing

November 22, 2016

Alia Hamdan never would have predicted that her scientific background gained at VCU, and her experiences as part of VCU Life Sciences’ 2013/2014 Panama Avian Field Ecology study abroad program, would earn her a place and fellowship at the Writers’ Colony at Dairy Hollow in Arkansas this past summer.

The return from Panama years ago found Hamdan spending the semester analyzing the data gathered, learning how to effectively present science to wide audiences, and communicating the importance of her work. She believes this, as well as several independent study and research courses she took while in Life Sciences, contributed greatly to her current success as she embraces her role as a first-time novelist. She wrote many project proposals, dossiers, and multiple drafts of scientific reports during her time at VCU. “My skills as a writer would be far less developed if I didn’t know how to communicate effectively to my perceived audience, a necessary component in any aspiring scientist’s work,” said Hamdan.

Hamdan’s experiences in Panama directly influence the shape and message of her novel, recalling the capability and self-awareness she found while in the field collecting vegetation data, handling songbirds, and getting constantly stuck in thoroughfares of sinking mud.  This out-of-the-classroom experience made her stronger and more resilient to life’s perceived challenges, however big or small. She learned how to keep going, especially when she had a goal in sight. It also influenced her to change her undergraduate research, focusing on Osprey and Bald Eagles with her research mentor, Dr. Cathy Viverette, who is credited as a great influencer on the course Hamdan has taken as a scientist. This led to her senior thesis project, poster publications, and presentations at the 2014 and 2015 VCU Rice Rivers Center Conferences.

“These events and persons, which I never would have experienced or encountered if I wasn’t a part of VCU and supported by everyone in the Center for Environmental Studies and Biology Departments, gave me the confidence to know what I want and learn how to approach it,” stated Hamdan. “I went to Panama to expand my knowledge base, to engage in the field that I pursued, and prove to myself that I could do this kind of work. I did, and after all these years, I realize that it made me into the person I am today.”

Rice Rivers Center researchers locate two juvenile Atlantic sturgeon

November 18, 2016

By Patrick Kane, University Public Affairs

When Matthew Balazik, Ph.D., told colleagues he planned to sample fish from the James River right before an important presentation at the Rice Rivers Center, they pressed him to be back on time.

Cutting his trip short, he set his nets to find fish closer to the center. There, Balazik found something he has spent the last decade searching for: a juvenile Atlantic sturgeon.

“I was pulling the net over the side of the boat. I went down to grab it, thinking it was a blue catfish,” he said.  “Once I saw what it was I just stood there and stared at it for probably 10 seconds.”

Rice Rivers Redeploys a Smart Buoy

November 6, 2016

By Virginia Commonwealth University

The newest member of the VCU Rice Rivers Center research team is standing tall in the James River, thanks to help from the U.S. Coast Guard Cutter Frank Drew and crew. 

Topped by solar panels, the smart buoy is packed to the gills with sensors measuring a variety of atmospheric and water conditions, plus the ability to track fish. 

“It will immediately begin to generate these very large databases we use for education and research,” said Greg Garman, Ph.D., director of the center. “We can see what water quality and chemistry in real time, weather conditions in real time and what fish species of interest may be in the river in real time.”

Tackling Urban Run-off

November 6, 2016

By Patrick Kane, University Public Affairs

When the rainclouds open up, the built environment of Richmond moves rainwater away from buildings and streets — but at the same time sweeps surface pollutants into the James River. Oil, gasoline, fertilizer, pesticides and animal waste are swept into the city’s stormwater drains by water flow.

VOSRP Fall Event 2016

October 17, 2016

It was a beautiful fall day in Richmond as a crowd gathered to enjoy food, cheer, and fun, at this year’s Shell Raiser’s Shindig.  The event, which took place on October 16 at Libbie Mill-Midtown, supported the Virginia Oyster Shell Recycling Program (VOSRP), a collaborative program of the VCU Rice Rivers Center.

Guests were able to sample dishes from some of the top chefs in Virginia, and also enjoyed regional beer, wine and cider.  

The program is active in Charlottesville, Richmond, Williamsburg, Hampton, Newport News, Norfolk, Suffolk Chesapeake, Portsmouth, Virginia Beach and Lancaster County, with almost 60 participating businesses and nearly 30 public drop-off locations. Volunteers also actively collect from oyster roasts and special events.

Annually, the program gathers more than 75,000 pounds of waste shell that is age-cured at the VCU Rice Rivers Center before being seeded with juvenile oysters. Those seeded shells are then returned to the Bay on reef restoration projects, working with restoration partners and the industry. Once all the shells collected from the prior year are seeded with juvenile oysters, more than 10 million oysters will be returned to the Chesapeake.

Peregrines and Bridges

October 8, 2016

By Bryan Watts

In the flat lands of the Coastal Plain, bridges check two of the “like” boxes for peregrines, and many of the most famous bridges across the globe have been colonized as peregrines have recovered over the past forty years. In Virginia, the relationship began in 1992 when a pair of falcons settled on a bridge across the York River and produced two young.  Since that time peregrines have used fourteen different bridges in the state and those bridges have made a significant contribution to the recovery of the population.  Over the past ten years, bridges have accounted for 26% of the young peregrines produced in the state. 

The Virginia Department of Transportation has been an essential partner in the recovery of peregrine falcons in Virginia.  Both environmental and operational staff has adjusted maintenance schedules to accommodate falcon breeding, helped to maintain and relocate nesting structures, participated in annual monitoring, and assisted biologists in accessing and banding young.  In 1998, the agency received the Federal Highway Administration’s Excellence Award in the category of Environmental Protection and Enhancements for their work to place peregrine nest boxes on bridges.

Although bridges serve as surrogates for natural cliffs on the Coastal Plain, they are lacking one feature compared to the real thing.  Winds that flow onto cliff faces produce updrafts that young peregrines just on the wing use to buoy them back up to their eyries.  Winds flow through the infrastructure of most bridges and do not produce updrafts.  The difference appears to increase the chance that young, inexperienced falcons will circle down into the water or onto lower bridge structures.  Beginning in 2000, a program was initiated to move some of the young from bridges to the mountains for release.  The effort has the dual objectives of increasing survival and recolonizing the historic mountain range.

Peregrine falcon work in Virginia is a large partnership effort led by the Virginia Department of Game & Inland Fisheries, The Center for Conservation Biology, Virginia Department of Transportation, National Park Service, Dominion, The Nature Conservancy, NASA, and the U.S. Fish and Wildlife Service.  

Whimbrel Conservation on the Acadian Peninsula

October 8, 2016

Fletcher Smith, Center for Conservation Biology

Atlantic Canada was documented as a major shorebird stopover location over a century ago. Very little regional population data was gathered on whimbrels since the market gunner/sport hunting days.  Those migrant shorebirds relied upon invertebrates and berries in bogs, heathlands, and mudflats to fuel their flights to wintering grounds. 

Beginning in the fall of 2014, The Center for Conservation Biology, along with collaborators at the Canadian Wildlife Service and Mount Allison University, surveyed the habitats available to whimbrels on the Acadian Peninsula of New Brunswick. During the fall migration of 2016, seven whimbrels were trapped and outfitted with small solar powered satellite transmitters.  The purpose of this study is to track the birds throughout their annual cycle, documenting habitat use while on the Acadian Peninsula, as well as to discover the wintering and breeding grounds of the birds that migrate through the region.

Funding, collaboration, and logistical support for this project was provided by the National Fish and Wildlife Foundation as part of the Atlantic Flyway Shorebird Initiative, the Canadian Wildlife Service, the U.S. Fish and Wildlife Service, Mount Allison University, the University of Moncton Shippagan Campus, and The Center for Conservation Biology at the College of William & Mary and Virginia Commonwealth University.  We thank the blueberry farmers that allowed access into select blueberry fields and assisted with logistics. 

Spring weather dampens woodpecker season

October 8, 2016

By Bryan Watts, Center for Conservation Biology

The 2016 spring season was challenging for both birds and biologists.  The consistent rain throughout the heart of the breeding season appeared to have an impact on breeding performance for many species throughout the mid-Atlantic region.  Bald eagles had small broods, osprey in the lower Chesapeake Bay had a very high failure rate, and peregrines had both small broods and a high failure rate.  Red-cockaded woodpeckers did not escape the impact with the lowest reproductive output in recent memory.  In terms of productivity, this year is comparable to the 2008 breeding season.

Eight woodpecker pairs produced 16 birds to fledging age, including 11 females and 5 males.  Three additional pairs made breeding attempts but produced no young.  Additional pairs were present within the site but did not attempt breeding.  No four-chick broods were produced in 2016.  Three pairs produced three-chick broods, two pairs produced two-chick broods and three pairs produced single chicks.  Despite low productivity during the breeding season, woodpeckers within Piney Grove Preserve continue to hold their own.  We can only hope that productivity will rebound in 2017.

Four birds remained within the Great Dismal Swamp National Wildlife Refuge during the spring of 2016.  All birds were released into the site during the fall of 2015.  Retained birds included three females and a single male.  The single male was paired with a female and the young couple prepared and maintained a nesting cavity through the spring, but eggs were never documented.  Additional birds will be moved into the refuge during the fall of 2016 to bolster the population with the hope of producing the first breeding attempts in 2017.

VCU Sturgeon Team Funded

September 29, 2016

VCU fish biologists working out of the Rice Rivers Center have focused for several years on understanding the biology and ecology of the federally endangered Atlantic Sturgeon in the Chesapeake Bay. Their work has put VCU on the forefront of endangered species research, including the development and testing of new technologies, such as acoustic telemetry and environmental DNA, for conservation and restoration efforts aimed at this iconic migratory species. In July, the VCU sturgeon team was funded for an additional three years by NOAA, the federal agency responsible for sturgeon recovery. Objectives for the competitive grant renewal will focus on the biology of early life history stages, the quantification of in-river threats, and development of GIS-based tools and data applications for state and federal managers. 

Addition to the VCU Rice Rivers Center Instruments

September 29, 2016

On August 19, 2016, a new instrument system was installed at the VCU Rice Rivers Center Pier.  Pandora 35 was contributed to VCU Center for Environmental Studies by Dr. Jay Hermann from NASA Goddard Space Flight Center by the generous sponsorship of Dr. Jack Kaye at NASA Headquarters.  The Pandora instrument system, which uses sun tracking to keep its upward-looking orientation, is an integral component of ground validation measurements for remotely-sensed atmospheric NOand ozone profiles. Nitrogen dioxide is an important trace gas to measure because of its role in the formation of photochemical smog which adversely affects human respiratory system. Ozone (near the ground) is also important to measure because it is produced from industrial and urban pollution.

Rice Rivers is honored to join the global Pandora system which includes sites from Harvard Smithsonian in Boston, MA, to Mauna Loa Observatory, Hawaii, to Innsbruck, Austria and many more. We are anticipating new partnerships and collaborations for both CES faculty and students as the result of the addition of the Pandora instrument system to the array of interdisciplinary instrument systems at the VCU Rice Rivers Center.

Citizen scientists work to fill the nightjar information gap

September 29, 2016

By Bryan Watts, Center for Conservation Biology

Over the past four decades there has been a growing concern within the conservation community that some species of nightjars are experiencing rapid declines over much of their breeding ranges.  Their ecology is poorly understood.  Because national monitoring programs are conducted during daylight hours and nightjars primarily call after dark, we have had very little information to assess changes in distribution and abundance.    

In 2007, The Center for Conservation Biology called on citizen scientists to help fill the information gap with nightjars by initiating the Nightjar Survey Network.  The response has been both gratifying and overwhelming.  An army of birdwatchers, agency biologists, and nightjar lovers have volunteered during the wee hours of the night to conduct standardized surveys of routes across North America.  The effort has resulted in the most comprehensive database to date on the group.

A total of more than 23,000 nightjars of nine species have been recorded during surveys.  We would like to express our gratitude to the many observers across the continent who have given of their time and expertise to make this effort possible.  Over the next year, CCB biologists will begin to explore the database for spatial and temporal patterns that will help with future nightjar management.  Moving forward, we hope to expand the volunteer base and survey network into additional areas that have received little coverage.

Mapping bald eagle movement corridors in the Northeast

September 29, 2016

By Bryan Watts, Center for Conservation Biology

With the establishment of many commercial-scale wind installations throughout the eastern United States and Canada has come a growing concern about the potential impact to migrating eagles.  Raptor migration corridors form around narrow ridgetops and coastlines that produce updrafts the birds use to facilitate soaring and gliding.  These same sites support the best wind profiles for commercial wind power generation.  Development of turbine fields within migration routes has the potential to cause population-level impacts.  One of the most effective strategies for reducing eagle and other raptor mortalities is to place turbines away from areas of high activity.  An impediment to implementing this strategy has been our inability to identify movement corridors.

In a recent paper published in Plos One, CCB biologists used satellite tracking data to delineate eagle migration corridors in the Northeast and overlay these corridors on maps of existing wind facilities and areas of viable wind-energy development.  A dynamic Brownian bridge movement model was used to process 132 individual migration tracks to create a utilization surface that delineated the movement corridors.  The work was funded by the American Wind Wildlife Institute and the U.S. Fish and Wildlife Service with the intent of informing the placement of future wind facilities in the Northeast.

Delineation of the movement corridors will be important for future wind development.  More than 2,000 existing wind turbines were within the highest two categories of eagle use.  However, only 6% of the area supporting the most commercially viable wind power classes overlapped with these eagle use areas, suggesting that a great many locations exist where wind may be captured outside of eagle movement areas.

Fruit availability and consumer demand within a migration bottleneck

September 27, 2016

By Bryan Watts, Center for Conservation Biology

During the fall of 2014, The Center for Conservation Biology, along with the U.S. Fish and Wildlife Service, conducted a study to examine the availability of fruit and which fruits were important to passerine migrants on the lower Delmarva Peninsula (download fruit availability report).  CCB technicians Sarah Rosche and Arianne Millet performed more than 2,000 vegetation assays to evaluate the composition and density of fruiting plants and the density of fruit production within selected forest and shrub patches.  They monitored nearly 500 fruiting branches of 12 species that supported more than 24,000 fruits weekly during the study period to assess patterns in fruit ripening.  These branches were included in an exclusion experiment (covered versus exposed) that we used to evaluate rates of fruit loss, fruit consumption, and fruit preference.

The seasonal schedule of fruit ripening varied dramatically between plant species such that the availability of ripe fruits changed during the migration period.  Some of the fruits, including American holly and hackberry, matured too late to have relevance for most migrants.  Based on the exclusion experiment, an index of consumption varied significantly between fruit species.  Sassafras, devil’s walkingstick, fox grapes, and autumn olive had consumption rates of more than 15% per week compared to hackberry, beautyberry, and bayberry that were less than 5% per week.  Fruit species fall into three preference categories including high demand, medium demand, and low demand.  Migrants stripped virtually 100% of fruits in the high demand category during the height of the migration season. 

Mature forest and shrub patches differ dramatically with respect to the composition of the fruiting plant community, plant density, fruit density, and the extent to which they support preferred fruit species.  Although fruit density within shrub habitat was more than ten-fold higher than forest patches, 95% of the crop is of low demand or is produced by an exotic invasive species.  Shrub patches should be managed to broaden out the fruiting plant community to include preferred fruit species.  Management prescriptions should be developed that drive the footprint of the less desirable plants down and expand the more desirable elements.

This field study follows a previous study by CCB that examined metabolic demand by migrants stopping over on the Lower Delmarva Peninsula and conservation limits (download conservation limits report). These projects have been completed to inform land management within this important staging site.  

CES Assesses Ecological Value

September 19, 2016

Saving green space and protecting healthy waters while balancing the need for economic development can be challenging for local governments.  In 2010, with the help of the VCU Center for Environmental Studies and other partners, the Virginia Department of Environmental Quality's Coastal Zone Management Program (CZM), released the Virginia Ecological Value Assessment (VEVA) to help show where important ecological areas are located in the coastal zone of Virginia.  This major breakthrough gave local governments a tool to assess the ecological value of potential sites, and hopefully to protect ecological resources.  

Now, CES has been awarded a contract from CZM to update this model and incorporate new data.  "This data set is important to the community because it provides localities with information on local, unique, and potentially highly valuable ecological resources." says Mr. William Shuart, a faculty member within CES.   The project will run for almost a year and the final products will be visible on CZM's data portal, Coastal Gems (www.coastalgems.org) that CES supports.

Ancarrow Wildflower Digital Archive Collaboration

August 30, 2016

The Ancarrow Wildflower Digital Archive builds on the Rice Rivers Center’s relationship with Lewis Ginter Botanical Garden to support outreach and research to the community.

Newton H. Ancarrow, Richmond’s earliest environmental activist, battled to improve water quality of the James River in the late 1960s.  Our founding river suffered from raw sewage and industrial waste and oil overflows that coated his boat ramp and the bottoms of his high quality speedboats after a heavy rain. He walked the banks of the James looking for sewage outflows and, on his journeys, documented over 400 species of wildflowers in what is now the James River Park System. The digital capture of his slide collection gives us a unique snapshot from the past to compare with the riparian flora of the present, a story of a crusade for clean water and conservation that still echoes today.

Record Breaking Haul for the VOSRP

August 11, 2016

The Virginia Oyster Shell Recycling Program (VOSRP) has had a busy spring and summer in the Richmond area. Recently, the program hauled the largest single volume of shell from Richmond at over 16,000 pounds, or more than 8 tons. Spat cages were deployed in the Piankatank to collect wild spat to be used on restoration sites. A reef was created in the lower Rappahannock with 1500 bushels of shell. The restaurants and public drop off locations who have partnered with this program can be found on the VOSRP Map. Lickinghole Creek Craft Brewery is one of these partners, and in addition to recycling, has partnered with the VA Oyster Shell Recycling Program to release the Seven Region Oyster Saison. This refreshing saison-style ale features farm-raised oysters from companies that partner with the VOSRP and represent seven of Virginia's oyster regions. Proceeds from the sale support oyster restoration and shell recycling. October 16 is the annual Shell Raisers Shindig that celebrates these partnerships that make the VA Oyster Shell Recycling Program successful. The public is welcome to join this event at Libby Mill Midtown for an afternoon of Virginia oysters, wine, beer, cider, and top chefs that participate in the Program such as Walter Bundy of Shagbark and Andrew Manning of Lucca Enotecca and Longoven.

Bioinformatics student wins Fulbright Fellowship

August 3, 2016

Ellen Korcovelos, from Richmond, Virginia, received her Bachelor of Science degree in bioinformatics in May 2016 from Virginia Commonwealth University and currently works at Commonwealth Computer Research Inc. (CCRi) as a data scientist. Though she now specializes in natural language processing and machine learning, Korcovelos spent her undergraduate years researching various facets of dementia. During this time, Korcovelos began developing computational means of analyzing the speech of patients with neurodegenerative disorders like Alzheimer's disease and Mild Cognitive Impairment. Korcovelos has presented her work at multiple conferences, including the National Council of Undergraduate Research, Capital Region Celebration of Women in Computing, and the Alzheimer's Association International Conference. Besides her research, Korcovelos also enjoys participating in activities that couple technology and medicine; she and her team won first place at HackDC for their mobile application for veterans with PTSD and third place at RamHacks for their mobile application tracking flu epidemics across the US. After her year spent completing a Fulbright Fellowship at the University of Toronto under Dr. Graeme Hirst and Dr. Frank Rudzicz, Korcovelos will return to the US to pursue a Ph.D. in computational linguistics and continue working at CCRi.

CES Represented at 2016 ESRI® User Conference

July 20, 2016

The Center for Environmental Studies (CES) was well represented at the 2016 ESRI® User Conference in San Diego, California.  ESRI®, the world’s largest geospatial software company, holds an annual user conference with 16,000+ attendees and invites users to present maps, posters, and oral presentations to an international audience focused on geospatial technologies.  ESRI® is the world’s leader in geographic information systems (GIS) software, and CES has been using the technology since 1993 to analyze spatial data.  CES faculty members Mr. William Shuart, Ms. Jennifer Ciminelli, and graduate student Mr. Wyatt Carpenter, who is also employed by VCU’s Office of Sustainability, attended the conference. 

Mr. William Shuart presented some of his research, “Evaluating Point Clouds - LiDAR and UAV's,” that was performed at the VCU Rice Rivers Center and used unmanned aerial vehicles (UAV's). UAV's can be used to collect aerial imagery that is useful in assessing the quality and health of wetland vegetation. CES and the VCU Rice Rivers Center will begin to implement the technology into their research and curriculum for students to provide them with a real world experience in near real-time data collection and processing. Mr. Shuart states, “Having access to industry leading UAV platforms is only part of the puzzle; understanding the data generated from them is where the answers lie.  Being able to produce 4 cm aerial imagery that is of a known quality in a couple of hours is the key to mitigating impacts to the environment.”  

Mr. Wyatt Carpenter's presentation “Worth it? Relating Landscape Composition & Residential Property Value” used GIS to focus on the potential financial benefit to real estate developers to preserve forested areas and wetlands in housing communities. Mr. Carpenter sums up the benefit of the conference to him personally this way: "One of my favorite parts of the conference was being in a huge group of people, all with different jobs, but connected by the common thread of GIS. Sharing that interest made it really easy to connect with other people and opened my eyes to the far-reaching applications of GIS."‌‌

Making History at the VCU Rice Rivers Center

July 11, 2016

History was made at the VCU Rice Rivers Center.  The first SET (Surface Elevation Table) was installed at 12:33 PM on Wednesday, May 25th 2016, and became a contributing partner investigating coastal wetland response to sea level rise in the NOAA Chesapeake Bay Sentinel Site Cooperative.  With the help of A.W. Demeo (VIMS), Claudia Deeg (a VIMS intern), Ron Lopez (M.S. ENVS 2017), Melissa Davis (M.S. ENVS 2016), Chris Gatens (ENVS 2016/BIOL 2016) and Dr. Ed Crawford (VCU, Biology), two SETs were successfully installed within Harris Creek, initiating our long-term study.  These two SETs (and others to follow) represent the first SETs installed in tidal forested wetlands within the James River watershed.  

Ron Lopez, one of the graduate students for this project, offers the following explanation on what exactly this project will provide:

Why SETs?

Accelerated rates of relative sea-level rise (RSLR) are predicted as a result of climate change.  While tidal freshwater wetlands have been able to keep pace with RSLR via self-regulating mechanisms of sediment accretion in the past, it is not certain that they can continue to keep pace.  Tidal forested freshwater wetlands, in particular, are understudied, and the understanding of their accretion dynamics is in its infancy.  With this study, researchers hope to gain insight into rates of elevation change, and influencing factors, in tidal forested freshwater wetlands in the James River watershed, as well as to gauge the success of the Kimages Creek restoration in terms of sediment accretion.

What are SETs?

The SET is a device for measuring elevation change relative to a fixed benchmark.  The instrument consists of a horizontal arm attached a vertical rod that is inserted into permanent benchmarks that have been installed in the substrate.  Through the horizontal arm run nine pins that are lowered to the sediment surface to take measurements.  Often used in conjunction with SETs are feldspar marker horizons, which are layers of white feldspar clay placed on the sediment surface that become buried as sedimentation occurs; sediment accretion can be measured by taking a core through the feldspar layer and measuring from the clay marker horizon to the sediment surface.  Using the array of SETs coupled with feldspar marker horizons, researchers will be measuring elevation change, sediment accretion, and shallow subsidence occurring within the wetland sites.  To date, 15 of the 18 first SETs (with the final three to be installed in James River National Wildlife Refuge July 12th) have been installed. The intention is to further expand the array of SETs to continue the advancement of this long-term study.

Where are the SETs?

For this research, observations and data collection will occur in three tidal forested freshwater wetlands:  Harris Creek (at the Rice Rivers Center), Presquile National Wildlife Refuge, and James River National Wildlife Refuge.  Additionally, researchers will be taking measurements in Kimages Creek (an ongoing restoration that previously existed as tidal forested freshwater wetland) in order to measure the success of the Kimages Creek restoration in the context of sediment accretion by comparing accretion measurements with those of the reference/ benchmark site at Harris Creek.  

In order to gain insight into some of the factors that may govern variability in our measured rates of accretion and elevation change, researchers will be measuring predictor variables at each site to include: aboveground vegetation density, aboveground surface roughness, distance to sediment source, tidal inundation parameters, and suspended sediment concentration within each channel.  Real Time Kinematic (RTK) base stations will be used to attain actual elevations at each site.  The state-of-the-art RTK units are capable of sub-centimeter accuracy in the z-coordinate, allowing for precise elevation measurements.  

Collaborative Research

In addition to bolstering the understanding of accretion dynamics in mature and restored tidal forested freshwater wetlands and allowing observation of elevation change in these ecosystems, this study marks a historical milestone for VCU Rice Rivers Center, as these SETs are the first installed in tidal forested freshwater wetlands in the James River watershed.  Furthermore, the partnership with the national wildlife refuges and the incorporation of data into the NOAA Chesapeake Bay Sentinel Sites Cooperative sets a precedent of cooperative information sharing and adaption to sea-level rise.  

Blood Work

July 8, 2016

By Bryan Watts, Center for Conservation Biology

Blood is a universal diagnostic tissue used to monitor a dizzying and expanding array of health indicators in humans.  Blood is particularly attractive as an indicator tissue because it is relatively easy and non-invasive to collect and it contains a host of constituents that have been shown to reflect a wide range of health conditions such as organ function, disease exposure, nutritional status, and cancer activity.  The ongoing increase in the number of health questions that may be addressed using only a blood sample is astounding.

Aside from the value of blood for veterinarian diagnostic purposes in pets and wildlife, bird blood has been used for decades to address a long list of ecological questions and to monitor environmental health.  Over the years, CCB biologists have collected blood from a long list of species often in collaboration with partners to monitor contaminant exposure in species of conservation concern or to investigate ecological questions.

 During the spring of 2016, CCB, in collaboration with the National Park Service, began a two-year investigation of contaminant exposure in eagles breeding on park service lands within the Chesapeake Bay.  Blood samples were collected from nestling eagles to investigate exposure to heavy metals and organic compounds.  The study is a sister project with a similar investigation on park service lands in the Great Lakes.  During their 100th anniversary year, the National Park Service continues to pursue an ethic of land stewardship that is a model for all.

Black-bellied Plovers Complete Annual Cycle

July 8, 2016

By Fletcher Smith, Center for Conservation Biology

Three black-bellied plovers have been tracked from their wintering grounds back to their breeding grounds, completing the annual cycle of this species.  These birds were originally tagged on Bathurst Island during the breeding season of 2015 by The Center for Conservation Biology and Canadian Wildlife Service staff.  These birds were tracked to a broad range of wintering locations, and recently migrated back to their breeding grounds.  This annual migration cycle of black-bellies was previously unknown and the study has begun to shed light on the behaviors and habitats of the plovers. 

The locations of the wintering grounds were somewhat surprising in that the plovers were spread along a 40 degree longitudinal gradient of the tropics (from Honduras to Brazil).  The majority (78%) of tracked shorebirds showed little variability in wintering location, especially in one breeding population/area.  This large winter range suggests that black-bellied plovers may be able to withstand local and potentially large scale pressures better than other shorebird species that concentrate in large numbers in narrow migration corridors (i.e. Whimbrel, Lesser Yellowlegs).

The plovers arrived on stopover grounds near Swanquarter, North Carolina, in Beaufort, South Carolina, and the north shore of Lake Erie, near Windsor, Ontario, in late April and early May.  One plover flew non-stop 3,400 miles from Brazil to North Carolina in roughly five days, which is both amazing and now expected.  After three weeks of feeding and resting at those stopover sites, the plovers were back on the wing, stopping along Lake Manitoba, and in the far northern reaches of Northwest Territories and Nunavut, Canada.  These stops lasted between a week and ten days with the pull of the breeding season winning out.  All three plovers arrived on breeding grounds in early to mid-June.  Understanding the linkages between these far-flung stopover sites will be critical in conservation of these and other shorebirds moving forward.

The Canadian Wildlife Service crew is back at Bathurst Island this summer and hopefully they observe good nesting success from the tracked plovers and the other birds of Bathurst Island.  The satellite tracking of black-bellied plovers is a collaborative effort between The Center for Conservation Biology at the College of William & Mary and Virginia Commonwealth University and the Canadian Wildlife Service, who initiated the tracking project in 2014. Logistical support for the Bathurst Island field expedition was provided by the Polar Continental Shelf Program in Resolute, Nunavut.  The tracking of the plovers is an ongoing project and the birds can be followed at Seaturtle.org.

Conservation in conflict: peregrines and shorebirds in the mid-Atlantic

July 7, 2016

By Bryan Watts, Center for Conservation Biology

The outer coast of the mid-Atlantic region has become an important site for the conservation of both breeding peregrine falcons and migratory shorebirds.  The region is a terminal, spring staging area where several shorebird species stop for an extended stay to build fat reserves for their final flight to arctic breeding grounds. The region has served this role for thousands of years and includes designated Western Hemisphere Shorebird Reserves with both “hemispheric” and “international” status as well as many conservation lands dedicated to shorebird protection.  The region is also the site where, during the 1970s, a decision was made to establish a breeding population of peregrine falcons to advance the cause of peregrine restoration in eastern North America. 

The eastern peregrine falcon was a casualty of the DDT era.  With no alternatives, the recovery team decided on a bold plan to stand up a captive breeding program and release birds into the wild.  After some experimental releases a fateful decision was made in 1975 to release birds on the outer Coastal Plain, a geographic area with no natural cliffs for nesting and no historic breeding population.  The hope was that a breeding population would be established that would ultimately colonize the historic Appalachian breeding range.  Between 1975 and 1985, 307 captive-reared peregrines were released on the Coastal Plain (VA to NJ) on artificial towers.  A breeding population was rapidly established that has blossomed to more than 70 pairs (read more about establishment of the coastal breeding population).  All of these pairs nest on man-made structures.

Migratory shorebirds make up the bulk of the prey used to feed peregrine broods on the outer coast and peregrines have adjusted their breeding season to capitalize on staging shorebirds.  Two independent studies of diet including one in Virginia and one in New Jersey have shown that shorebirds account for more than 70% of the prey used to feed young.  As the peregrine population has grown over the past 30 years, the annual take of staging shorebirds is now estimated to be several thousand.  Several shorebird species seem to receive the most attention including dunlin, short-billed dowitcher, black-bellied plover, willet, and some red knots.  A sample of video footage from 2016 on one pair for seven days included 12 dunlin, 4 semipalmated plover, 1 American oystercatcher, 1 willet, 1 black-bellied plover, 1 ruddy turnstone, 1 short-billed dowitcher, and 1 spotted sandpiper.

The establishment of a robust breeding population of peregrine falcons within one of the most significant shorebird staging sites along the Western Atlantic Flyway represents a conflict between opposing conservation objectives.  Of the 35 shorebird populations that use the flyway, 65% are declining.  Some believe that the establishment of the peregrine breeding population may be contributing to these declines.  For some shorebird species, the estimated take by the peregrine population may approach sustainable mortality limits (read more about sustainable mortality limits for shorebirds), suggesting that the population may be contributing to declines.       

One possible management solution may be to translocate young peregrines from the outer coast to the mountains for release.  The Virginia Department of Game & Inland Fisheries, the National Park Service and CCB have had a long-term partnership of moving birds to mountain hack sites (read more about this hacking program).  The focus of this program has been to re-establish breeding falcons within the historic mountain range while increasing the survival of young peregrines reared in hazardous locations.  A third objective of moving birds from the outer coast would be to provide relief to migratory shorebirds by greatly reducing the number of mouths to feed.

The win-win-win program of moving young peregrines to the mountains would mitigate some of the conservation conflict between breeding peregrines and staging shorebirds.  A modest amount of funding is needed to expand the hacking program to accommodate the young peregrines.

Virginia bald eagle breeding population exceeds 1,000 pairs

July 1, 2016

By Bryan Watts, Center for Conservation Biology

(Williamsburg, VA)---The Center for Conservation Biology at the College of William and Mary and Virginia Commonwealth University has compiled 2016 survey results for the Virginia bald eagle population.  After more than 160 hours of aerial surveys, ground efforts in residential areas of lower Tidewater, and observations from inland volunteers, the survey documented 1,070 occupied breeding territories.  This result continues the dramatic year over year recovery documented over the past 40 years.  The population had fallen to a low of 20 pairs by 1970.  A federal ban on the use of DDT and like compounds in 1972 initiated a recovery by the late 1970s.  By 2007, the population had reached 500 pairs for the first time in the modern era.  The 2016 survey mapped eagle territories within 57 counties and 12 independent cities.  The highest breeding densities continue to be in counties situated around major tributaries of the Chesapeake Bay with highest numbers including 75 pairs in Westmoreland County, 73 pairs in King George County and 71 pairs in Essex County.

 In addition to the historic breach of the 1,000-pair barrier, this season marks some notable survey anniversaries.  2016 represents the 60th year of the annual eagle survey initiated by Jackson Abbott and volunteers of the Virginia Society of Ornithology.  In addition to this incredible milestone, the 2016 survey represents the 40th year of Mitchell Byrd’s tenure, the 25th year of Bryan Watts’ tenure conducting the survey, and the 25th year of Captain Fuzzzo Shermer piloting the survey.  Together, this young team has logged more than 3,500 hours of eagle survey flights, more than 24,000 nest checks, and documented the production of more than 15,000 eaglets.  It has been one amazing ride.

 The Virginia Bald Eagle Survey is a national treasure. The survey has become one of the most significant serial data sets in the world. More than population information alone, the effort has produced a wealth of ecological information on a population recovering within an increasingly human-dominated landscape. It has become one of the best records of arguably the greatest conservation accomplishment in our nation’s history. Since 2009, results of the survey have been made available on CCB’s website via an interactive mapping portal where users are able to view known nest locations throughout the state. The web application receives more than 30,000 visits per year and has become a critical resource for land planners.

 The 2016 survey was sponsored by the Virginia Department of Transportation, the National Park Service, Dominion, the U.S. Department of Defense, the U.S. Fish and Wildlife Service, the U.S. Army Corps of Engineers, and The Center for Conservation Biology.  Reese Lukei managed the ground survey in lower Tidewater, Bart Paxton assisted with aerial surveys on the upper Potomac and many observers throughout the state provided observations of nesting activity.  We thank all of these organizations and great observers for their commitment to eagle conservation in Virginia.

First-ever drone course to be offered at Rice Rivers Center

June 30, 2016

This summer, the Center for Environmental Studies will begin the first course on the scientific application of drone technology held at VCU. ENVS-591: Environmental Applications of Drone Technology will be a one-credit, two-day intensive course, and will be held at the VCU Rice Rivers Center.

The use of drone technology is well-suited to the ecological and environmental sciences, and emerging sensor technologies will allow scientists to gather higher resolution data faster.  In this course, students will receive exposure to technical software related to the operation of the UAVs, and also will learn how to create elevation point clouds, elevation models and compute vegetation indices. Training will be on industry-leading fixed-wing and multi-rotor platforms. Real-time kinematic GPS and control, along with web application display, will enable each student to create usable output from the data collected in flight. Students also will be exposed to flight planning, safe operation, and regulations regarding use of UAVs.

This cutting-edge technology will equip students with a marketable skill that will dramatically further their potential as researchers.

Yellow-crowned night herons adjust to changing climate

June 30, 2016

By Bryan Watts, Center for Conservation Biology

Yellow-crowned Night Herons are showing a clear response to the earlier and earlier appearance of spring temperatures in Virginia.  The 2015 breeding season was the earliest recorded with pairs arriving and laying eggs more than 20 days earlier than pairs recorded in the same breeding areas during the 1960s.  This trend continued in 2016 with pairs arriving and laying eggs (on average) a full week earlier than 2015.  The birds are proving to be a sensitive barometer of shifts in regional temperatures. 

The yellow-crowned night heron is primarily a tropical species with four of the five living forms being sedentary and confined to tropical latitudes.  All forms are crab specialists, exploiting a wide range of crabs adapted to their locality.  A study of crab use in Virginia during the 1980s (Watts 1988) collected and identified more than 2,000 crab claws from under nests and determined that three species including the mud fiddler, the red-jointed fiddler, and the white-fingered mud crab accounted for 94% of the diet with the sand fiddler, ghost crab, blue crab, mole crab, toad crab, and common mud crab accounting for the remainder.  The three dominant species occur in salt marshes and associated shallows.

Yellow-crowned night herons that breed in Virginia are migratory and their arrival on the breeding grounds is closely tuned to the emergence of crabs in the spring.  Emergence of crabs is very sensitive to temperature.  When the temperature rises above 15°C (59°F), they emerge from their burrows and become active.  Crabs retreat to their burrows and move underground when the temperature drops below 15°C.  The date in spring when temperature passes the 15°C threshold is advancing, extending the season of fiddler availability.  Yellow-crowns appear to be adjusting to the shift in season.    

The 2016 season is the second in a multi-year study to compare the breeding ecology of the yellow-crowned night heron to a study conducted within the same colonies in the 1960s.  The ten-year dataset from the 1960s was collected by Constance DuPont Darden.  Mrs. Darden (former first lady of Virginia) was passionate about yellow-crowns, and her information has contributed a great deal to our understanding of the species.  Her dataset is housed within The Center for Conservation Biology.

Climate change is a change in the statistical properties of the climate system over long periods of time.  Regardless of the underlying causes of this change, the earth has been experiencing a documented shift in climate for decades.  How wild species respond to changes in climate will determine many aspects of their ecology including their geographic distribution, the timing of significant events in their annual cycle, and for some their survival.  Understanding the implications of these shifts is a growing focus of conservation biology.  Because of both their migratory status and specialized diet, yellow-crowned night herons represent a model system for investigating how species respond to a changing climate.   

Assessment of shorebird hunting policies published

June 29, 2016

By Bryan Watts, Center for Conservation Biology 

One of the greatest challenges in managing migratory birds is that they exist within a legal quandary. As a recognized principle of international law, states have sovereign rights over all wild animals that fall within their jurisdictional boundaries but no jurisdiction over animals outside of these boundaries. The practical result of this principle is that animals that migrate from one jurisdiction to another are subject, in succession, to the sovereign rights and policies of all states along their migration route. According to conventional international law, there is nothing to prevent a jurisdiction from overexploiting a migratory species to the point of extinction while other jurisdictions expend considerable resources to protect it. Because a migratory population represents a single biological unit, cooperation among range states is critical to successful management.

Shorebirds are among the bird groups of highest conservation concern in the world with three times as many species declining as increasing.  In recent years, unregulated hunting has been identified as a possible driver of declines particularly within the Western Atlantic and East Asia-Australian Flyways.  A significant barrier to progress toward holistic management is that we currently have no comprehensive overview of the patchwork of policies that regulate shorebird hunting across the Western Hemisphere.

In 2015 with funding from the U.S. Fish and Wildlife Service, CCB conducted a comprehensive assessment of hunting policies pertaining to shorebirds for the 57 jurisdictions within the Western Hemisphere.  The assessment (Watts and Turrin 2016) was recently published in “Wader Study” the international journal devoted to shorebird ecology and conservation.  We focused on participation in international treaties and the existence and terms of domestic legislation with respect to the subsistence, commercial and sport hunting of shorebirds.

Most (91.2%) jurisdictions fall into two policy categories, including those that protect all or nearly all (>90%) and those that protect very few (<10%) migratory shorebird species.  The former includes 39 (68.4%) jurisdictions, 29 of which have complete prohibitions on shorebird hunting. One of the most interesting findings of the study was that ten of 11 jurisdictions where sport hunting of shorebirds is legal and practiced are exclusive to the Atlantic Flyway.  Shorebird hunting jurisdictions are concentrated within the Lesser Antilles where hunters capitalize on waves of shorebirds that are “put down” on the islands by tropical storms in the late summer and early fall period.

The presumptive objective of hunting policy is to ensure the future health of hunted populations by limiting take to or below the limits of what populations are capable of withstanding.  An immediate conservation priority for migratory shorebirds within the Western Hemisphere is to make policy adjustments that will prevent the collective harvest from exceeding sustainable limits.  A recent paper (Watts et al. 2015) published in Wader Study estimates sustainable mortality limits for shorebird populations within the Western Atlantic Flyway.  Estimates of sustainable mortality limits in combination with the recent assessment of current policies points the way forward. 

Fisheries meeting held at Rice

June 28, 2016

Virginia Commonwealth University recently hosted the annual meeting of the Sustainable Fisheries Goal Implementation Team at the VCU Rice Rivers Center. The Fisheries GIT is a consortium of federal and state agencies that manage important Chesapeake Bay commercial fisheries, including Blue Crabs, Oysters, and Striped Bass. During the two-day meeting, over fifty academic scientists, agency biologists, and resource managers from throughout the Bay Region took part in technical presentations and heard about VCU's own applied research initiatives related to water quality, ecosystem restoration, fishery ecology, and environmental technology.

Researcher investigates environmentally friendly mosquito management

June 27, 2016

By Rachel Machacek, University Public Affairs

Virginia Commonwealth University alumna Katie Bellile has always been very clear about what she wants. From a young age she knew she wanted to go to VCU and immerse herself in environmental studies.

Bellile, 28, grew up in Richmond around the university where her mom was working toward a master’s degree in urban planning. She remembers being inspired by the Eugene P. and Lois E. Trani Center for Life Sciences building, which was new at the time.

Last year, Bellile graduated with a master’s degree in environmental studies in Life Sciences after completing her undergraduate degree in the same discipline, and started her career at Stantec as an environmental planner, protecting limited freshwater resources. Now, the research she conducted as an undergraduate student has been published — a unique achievement. And she has done it all as a single mom.

Bellile’s paper is an investigation of environmentally friendly mosquito management. Specifically, she looked at the combination of biological pesticides and leaf litter in controlling the emergence of adult mosquitoes from the egg and larval stages. The paper was published this month in the Journal of Vector Ecology, and is the culmination of research Bellile conducted with her faculty mentor James Vonesh, Ph.D., associate professor in the VCU Department of Biology in the College of Humanities and Sciences.

We caught up with Bellile recently to talk about her work and the newly published paper.

How did you become interested in pesticides and mosquitoes?

My original interest was chemical pesticides from agricultural use getting into the freshwater system. I began to look at some of the problems associated with these pesticides and it led me to an interest in biological pesticides, which are better for the environment in general.

How so?

So far, research shows that biological pesticides like Bti [Bacillus thuringiensis serotype israelensis] primarily target mosquitoes and don’t have large effects on the rest of the community. So frogs, for example, aren’t directly inhibited by products like Bti.

So why wouldn’t everyone use Bti?

Well, I started looking into the existing literature only to find that even though Bti has been examined by many scientists, there was not consistency in its efficacy. Sometimes it reduced adult mosquito emergence 99 percent and, other times, less than 30 percent, so there must be an agent increasing or decreasing its efficacy. But what? 

And the sleuthing begins. What did you find out?

When I read through all the literature, I realized quantity of leaf litter around mosquito breeding grounds is a constantly changing factor. I thought perhaps there is a relationship to the amount of leaf litter and the changing efficacy of Bti.

What did you observe in your research?

That leaf litter in combination with Bti created an ovitrap. Essentially, the leaf litter encouraged the mosquitos to come to the site and lay their eggs rafts there and Bti would have greater effect because there was a larger mosquito population present.

So you tricked the mother mosquitoes into depositing their eggs in an egg-friendly amount of leaf litter and then used Bti to kill the larvae?

Yes. Instead of deterring mosquitoes from laying eggs in your yard, stream or river, you gather a larger population at your site and therefore you’re able to get rid of more of them. My observation showed that they were less likely to colonize an area that only had Bti or low leaf litter than they are to colonize an area that has high leaf litter.

That must have been a lot of mosquito egg counting to verify your results.

That was actually the highlight — exploring the communities that established in my mesocosms. I loved collecting the data. I loved keeping count of every egg raft. I loved the feeling of accomplishment after I spent six hours with my face one inch above the water counting egg rafts or using a turkey baster to suck adult mosquitoes from the emergence trap. I loved that it was hard. 

It’s a lot of work. Were you working on your own?

I did decided on the plan on my own and kept detailed records, found volunteers, set up the experimental area, monitored my mesocosms and collected data. My research assistant, who is now my husband, helped with the heavy lifting of mesocosms and tasks that required someone to take measurements while someone else wrote data down.

What were you surprised to learn?

How hard it is to spend a year developing an idea, a year performing the experiment and then trying to squeeze all the hard work you’ve done into something someone will actually read. If I had it my way, my paper would have been 30 pages long. Dr. Vonesh and I worked really hard to use concise language and it’s less than 10 pages now. I really wanted readers to know all the work that had gone into it and all that I had learned, but instead I learned how to stick to the facts that are pertinent to your main idea and eliminating everything else. 

What was your biggest challenge? 

This was a complex project with multiple factors. I was looking at Bti presence and absence, leaf litter presence and absence, as well as mosquito emergence numbers in over 28 mesocosms. Presenting the data so it displays in a way that is accurate and defensible are factors that go into statistical analysis. Wrapping my head around all the math that had come from my own idea was wild. 

And what was the highlight?

Really it’s being a scientist for the first time because it’s something I’ve wanted for so long and worked so hard for the privilege of doing an experiment at the VCU Rice Rivers Center. I was excited the whole time I was doing fieldwork. I truly love the time I spend alone studying the woods and water. It allows me to put space in my soul. 

You were raising a young daughter alone the entire time you were in school. How did you stay motivated and on track?

I have a strong supportive family who never let me feel like being a young single mom should stop me. My daughter has been my constant motivation. I knew I had to study really hard to be the best I could be for her. I read a lot of my textbooks to my daughter as bedtime stories so she has benefited tremendously. She, too, is a straight-A student.

Evolving science: VCU Rice Rivers Center hosts seventh annual research symposium

June 13, 2016

By Rachel Machacek, University Public Affairs

A new frog species, a look at songbird population dynamics in the nonbreeding season, a device to simulate sea-level rise, and how urbanization could be affecting inchworms were among the topics presented at the Virginia Commonwealth University Rice Rivers Center Research Symposium last month.

More than 80 scientists and researchers filled a room overlooking the James River to hear 10 presentations and watch two short films at the symposium. The afternoon included a poster session and a tribute to Leonard Smock, Ph.D., director of VCU Rice Rivers Center and interim vice provost of VCU Life Sciences, who is retiring this year.

Smock noted the evolution of life sciences research over the years. “When we started the wetland restoration, the only research going on out there was plant ecology,” Smock said. “Now, it has matured considerably to take in global climate change and rising sea level impacts on the wetlands.”

He credits an investment in environmental technologies for expanding the scope of what researchers can do.

Dong Lee, Ph.D., postdoctoral researcher in the Department of Biology in the College of Humanities and Sciences, has been building electronic devices to assist biologists in their work. In his presentation he emphasized that commercial devices often do not answer the needs for a researcher’s specific work, may be cost prohibitive or could be both. Lee’s solution is to make your own. He demonstrated his DIY approach with a project to build a water pump that simulates sea-level rise in tidal freshwater wetlands.

“I’m thinking a lot of these students and faculty are saying, ‘Hey wait a minute. I can use a sensor to do XYZ. I’m going down to the lab and see if he can’t build that for me,’” Smock said.

Urbanization and the inchworm

Abigail Nelson, a graduate student in the Department of Biology, researched the effects of urbanization on a species of moth called the fall cankerworm, otherwise known as the inchworm.

Cankerworms may be small, but they make their presence known in their eating habits, feeding on the leaves of deciduous trees. Periodic outbreaks can severely defoliate trees. “They eat new leaves on trees, which can be more damaging,” Nelson said.

She wanted to see if urbanization is playing a role in these larger outbreaks – specifically how urbanization affects the parasitic wasp that feeds on cankerworm eggs, effectively suppressing their populations.

“More and more people are flocking to urban areas and there’s more development to keep up with population,” she said. If development is wiping out parasitic wasp populations that keep inchworm populations in check, what does that mean for the trees and forests?

Nelson has long been interested in population ecology, or how species interact with the environment. When she started working in the Johnson Lab, she realized that looking at insects is one key to understanding this. “There are so many of them. You can get a great idea of what’s actually happening in the ecosystem,” she said.

Over two years, Nelson studied cankerworm and parasitic wasp populations at rural and urban sites in Central Virginia, including one at the VCU Rice Rivers Center. She found that in the second year, fall cankerworm abundance declined at every site and identified significantly more parasitoids during that time, but “there was no significant effect of urbanization,” she said. However, her research suggests that the parasitoids may be regulating the fall cankerworm.

What’s ailing the prothonotary warbler?

Biology graduate student Jesse Reese is also interested in looking at species population. Her research is focused on conservation efforts for the prothonotary warbler, a declining songbird species. “My research deals with understanding how populations on the breeding ground are linked to populations on the wintering ground,” she said.

Most of the research on migratory birds happens during the breeding season. To fill knowledge gaps, Reese studied habitat use and quality of the prothonotary warbler’s nonbreeding grounds to get an understanding of their survival over the winter season.

During a month-long trip to the Caribbean coast of northern Colombia earlier this year, she looked at population density and took feather samples from five different sites. Studying plumage is helpful because birds often grow their feathers on breeding grounds so the samples will actually give her information about where specific birds breed.

Next steps will be to analyze the feathers in the lab and see if the birds are coming from the northern or southern part of the breeding range. By comparing populations between seasons, researchers can understand better what factors impact populations. From there, they can establish targeted conservation measures.

A new frog arrives in Virginia

A new species of frog, the Atlantic Coast leopard frog, was discovered in Staten Island, New York several years ago and announced in 2012. That same year, J.D. Kleopfer, herpetologist at the Virginia Department of Game and Inland Fisheries, discovered the species in Virginia.

Kleopfer, a collaborator with the Rice Rivers Center, has been working on confirming the Atlantic Coast leopard frog’s status as a new species in Virginia by analyzing genetic samples, physical characteristics and bioacoustics. In fact, the tip off for him was an unusual-sounding frog chorus—more of a quacking than the warbling chuckle of the Southern leopard frog, a very similar species. He had originally dismissed this observation and it was a year before he revisited what he had heard to confirm this chance discovery.

Based on his experience, Kleopfer had encouraging words for the room, in particular young biologists and conservationists: “You’ve got to be able to pay attention. Get out there and, if you notice something that makes you cock your head a little bit, pay attention to it because you never know what you’re going to find.”

Black Lights and Owls IX

June 1, 2016

For the ninth year in a row, Black Light and Owls (BLO) recently drew a wonderfully engaged crowd of citizen scientists out to the Rice Rivers Center and the USFWS Harrison Lake National Fish Hatchery. A collaboration between Dr. Art Evans and Anne Wright, VCU Rice Rivers Center Director of Outreach Education, BLO was initiated as an advanced training opportunity for volunteers from chapters of the Virginia Master Naturalists program. It is a great opportunity to learn more about how insect sampling is done, to learn the identification and natural history information about the bug species that come to the lights, and have the chance to practice insect and macro photography. Insects collected add to the Rice Rivers Center reference collection of insects being amassed by Dr. Evans. 

On May 28, approximately 80 people participated, with about a third of them camping out at the Rice Rivers Center for the evening. The event is held overnight because the lights draw different suites of species every few hours from dusk to dawn. Around midnight, three barred owls responded to calls made by Wright. Additionally, a number of  frog species were active and calling, giving the Master Naturalist members a chance to practice their frog call identifying skills.

Measuring flux: New meteorological tower at the Rice Rivers Center

May 31, 2016

By Rachel Machacek, University Public Affairs

Standing at the edge of the wetlands at the VCU Rice Rivers Center, a 20-foot aluminum tower stands juxtaposed among the wild plants and grasses. There is no detectable movement from its perch on a wooden platform, but it is furiously recording data all day, every day — perhaps the hardest-working researcher in the field.

Gas and wind sensors mounted to the flux tower — aka Rice Rivers Atmosphere Biosphere Interaction Tower, aka Marsh RRABIT — are set to 20 hertz. That means the measurements fly in at frequencies up to 20 times per second. On the whole, the tower instruments collect about 1.7 million records per day on wind speed and direction, carbon dioxide and methane concentrations, precipitation, air temperature, soil temperature and moisture, light, the works.

In any environment, it can be challenging to get an accurate picture of what the atmosphere and terrain are doing. Normally, scientists manually take measurements and samples from smaller locations daily, weekly, monthly.

“You could walk out here and measure over the course of a season how much plant material is produced and you can look at how much carbon gets stored in the soil,” said Scott Neubauer, Ph.D., assistant professor in the Department of Biology in the College of Humanities and Sciences who is jointly leading the project with Chris Gough, Ph.D., assistant research professor in the Department of Biology. “These snapshots-in-time provide a batch of observable data, but it’s limited.”

The 12 instruments mounted to and around Marsh RRABIT are inherently more efficient and faster, providing a constant stream of micrometeorological information. It is a bit of a game changer, though it does not mean scientists can now kick back behind a desk, never to hoof it out to the field in waders again.

The flux tower data will tell researchers how much carbon and methane is going in and out of the footprint it measures (roughly 25 acres from its position to the edge of the forest), and then it is the researchers’ job to get on the ground and figure out where the carbon ends up — in the soil, plants and trees.

“If you can approach it from two different ways, on the ground and an independent approach with a tower, then you can converge on an estimate for greenhouse gas fluxes,” Gough said. “It increases our confidence in the estimates we’re making.”

Discovering the wetland

VCU Life Sciences purchased the tower through funding allocated from the Higher Education Equipment Trust Fund, which provides resources to upgrade equipment needed for instruction and research. It is the first tower to be put in a restored freshwater tidal wetland, an ecological system scientists do not know a ton about, particularly in regards to methane and carbon dioxide coming in and out of the atmosphere. In 2011, the wetlands were restored under a project with the Nature Conservancy.

Understanding the functioning of this type of wetland is at the heart of the project, as is being able to track how a restored wetland functions.

“There are tons of wetlands that have been destroyed all over the U.S. historically, and now, especially after Hurricane Katrina got a lot of attention, people are trying to restore them,” said Ellen Stuart-Haentjens, a Ph.D. student in the VCU Integrative Life Sciences Program. The flux tower project is central to her doctoral research, and she helped assemble and configure the tower.

Wetlands act as sinks for greenhouse gases and are also substantial sources of methane. They help with flood control, protect soil from erosion, and filter water to keep out pollution and toxins. When wetlands are not fully functioning, they simply do not do their job as well.

It is unknown if restored wetlands like the one at the VCU Rice Rivers Center are actually sequestering the same amounts of carbon or emitting similar amounts of methane as an established wetland, and they present a number of scientific question marks for researchers.

“There are very few restored wetlands that people have taken at least carbon measurements out of, so this is going to be one of the first studies looking at that,” Stuart-Haentjens said. “If restored wetlands are not functioning up to what they should be, should we have more regulations on what we do with our wetlands? Or should we change the way we are restoring our wetlands?”

With the new data set, researchers can get answers to these questions and, by being able to precisely quantify the greenhouse gas fluxes between the wetland and atmosphere, produce better predictive models of the carbon cycle.

Data in real time

William Shuart, director of information technology at the VCU Rice Rivers Center, is working on getting the tower hooked up to Wi-Fi so data can be transmitted to a server at the Trani Life Sciences Building on campus. Shuart and Jennifer Ciminelli, data manager and research coordinator, are the keepers of the data. Once the Wi-Fi connection is established, Stuart-Haentjens can begin monitoring the tower remotely from her laptop or even through an app on her cell phone, making sure the instruments are working and that there are no glitches.

Remote access is something that has only just become accessible in the past 10 years, and the technology has revolutionized researchers’ ability to capture high-frequency ecological data from ecosystems, according to Gough.

“What happens is, every 15 minutes or so, the system will transmit data back to one of our servers here on campus and it’s stored in a database,” Shuart said. “We’ll have a website where people can go and look at the current atmospheric conditions at the VCU Rice Rivers Center, what the tide is doing, how much dissolved oxygen is available, etc. Now we have more detailed microclimatology data available.” (Think of the data and graphs on the National Oceanic and Atmospheric Administration’s website, but on a hyperlocal scale.)

It also allows researchers to share data online in real time, creating a potent teaching and learning platform for VCU professors and students and even those outside of the university interested in the data.

“Tons of courses could benefit from a real-time data stream because you can see what the wetland is doing on any given day,” Gough said. “It makes it more accessible to students because you can say, ‘Hey, it’s sunny and spring. What do you think is going on today based on the theoretical stuff we’ve talked about?’ Then the student can actually see what’s happening in real time and test their hypothesis.”

The hope is that the data will also inform other research, transcending the original questions being asked regarding greenhouse gases.

“So somebody could be interested in what’s happening in Kimages Creek, and they could look at our flux tower data to figure out what’s happening when the tide is up and the whole marsh is creek, and get estimates of what flux is coming from the water,” Neubauer said. “We can see it informing lots of individual scientific questions and allowing others to build off the data.”

Power in numbers

When it comes to flux towers and the micrometeorological data they track, there is power in the aggregate — to take slices of regional and national data in order to understand on a global scale how ecosystems affect climate, and also the other way around. Ultimately, the goal is to generate usable science that could influence policymakers to create regulations around protecting the environment.

The flux tower is about 20 feet tall and 12 sensors are mounted to the frame.

The first tower went up in 1990 at Harvard Forest, and there are now about 700 flux towers around the world, many connected to FLUXNET, a global aggregate of tower networks. There also is AmeriFlux, a U.S. and South American network that Marsh RRABIT will join in December as soon as they meet the criteria of having a year’s worth of data.

“This is for people to do large-scale syntheses and models,” Stuart-Haentjens said. “If you have all the information from several ecosystems in the whole U.S., then you can do a lot more.”

For now, the VCU team is part of a group of Virginia-based flux tower scientists called VAFlux. They are working together to determine how they can use combined tower data to develop a carbon footprint for Virginia.

“We have so many ecosystems represented and if you know the kinds of carbon coming in and out of each other’s ecosystems, you can make a model for the whole state,” Stuart-Haentjens said.

VAFlux is also considering how to use the towers as a tool to teach middle and high school students about ecosystem fluxes, and potentially developing a travel course for international students and researchers who are trying to set up and interpret data from their own tower.

The flux tower technology is part of an ongoing effort within VCU Life Sciences to build an infrastructure at the VCU Rice Rivers Center with a broad range of applications that can facilitate a multitude of long-term research projects. It joins a suite of technology and tools, including tidal gages to measure water level and quality and three unmanned aerial vehicles, that give researchers the big picture of what the environment is doing over time. It represents a significant investment in VCU’s research mission.

Oyster Restoration Day at Rice

May 25, 2016

On April 17, the Virginia Oyster Shell Recycling Program (VOSRP) held an oyster restoration day at the VCU Rice Rivers Center. A group of VCU honors students, graduate students, faculty and Program volunteers worked to construct spat cages, spat bags and a shell cleaning station.

Don Abernathy of Deltaville Oyster Company and Matt Schwab (VCU Class of 2014) of Hold Fast Oysters helped direct the efforts, and the day included a short discussion about the VOSRP, oyster restoration and some of the work at the Rice Rivers Center. 

Many thanks to VCU Honors College, Biology at VCU, the newly-formed VCU Society for Ecological Restoration (SER), Deltaville Oyster Company, LLC, Hold Fast Oysters and VOSRP partners and volunteers.

 

Bukaveckas’ research a helpful link for water quality problems in Western Australia

May 24, 2016

On May 4, Dr. Paul Bukaveckas gave a seminar at the Oceans Institute at the University of Western Australia, as part of the OI Futures Forum. In his talk titled “Mechanisms Driving Phytoplankton Turnover”, Dr. Bukaveckas addressed the fact that there is long-standing interest in the role of ‘top-down’ and ‘bottom-up’ forces in regulating material and energy cycling within ecosystems.  

An applied aspect of this problem concerns top-down effects that may mitigate (via grazing) or exacerbate (via nutrient recycling) the effects of nutrient enrichment on aquatic primary production.  Researchers at the Rice Rivers Center quantified the abundance, feeding and diet of zooplankton, benthic filter-feeders, and planktivorous and detritivorous fish in the tidal-fresh segment of the James River Estuary to assess the importance of primary consumers in removing phytoplankton biomass and recycling nutrients.  They found that consumer-mediated fluxes of chlorophyll A and nitrogen were small in comparison to other fluxes regulating phytoplankton abundance (production, respiration, advection) and nitrogen availability (external inputs, internal recycling).  This finding has implications for understanding the mechanisms that regulate turnover of chlorophyll, nitrogen and phosphorous in phytoplankton communities.

Dr. Bukaveckas is a Professor in the Department of Biology at Virginia Commonwealth University and holds a joint appointment with the Center for Environmental Studies. His area of expertise is Phytoplankton Ecology with a focus on factors controlling algal production and the role of primary producers in nutrient and organic matter cycling. His research includes studies of the effects of nutrient inputs on streams, rivers, and estuaries in the United States, Eastern Europe and Western Australia. His current work focuses on the occurrence of harmful algal blooms and water quality problems in the James River, a sub-estuary of Chesapeake Bay; similar problems are arising from nutrient inputs to estuaries along the western coast of Australia.

Wetlands walk attracts engaged crowd

May 24, 2016

On April 9, Joe Morina, a graduate student in VCU’s Biology Department, led a wetlands walk at the Rice Rivers Center. In his role as a Virginia Sea Grant Graduate Research Fellow, and in coordination with the Chesapeake Bay Foundation, he led 18 participants on the walk who wished to learn more about wetland ecosystems. 

A group that included master naturalists and wastewater treatment workers learned about wetland ecology and the extensive wetland restoration efforts at the Rice Rivers Center. At the restored wetland, Morina demonstrated some basic methods of wetlands research, including sampling a soil core, viewing gas flux chambers, and understanding the use of litter bags for measuring decomposition rates or performing soil transplants. Lastly, the group walked to the swamp and discussed the differences in ecosystem function between the marsh and the swamp. The walk concluded with a discussion focusing on the importance of wetland ecosystems to water quality. 

Sutherland Elementary School students get first-hand science experience

May 23, 2016

VCU’s Graduate Organization of Biology Students (GOBS) organized an outreach event on April 8 at Sutherland Elementary School. Six graduate students installed mesocosms (large experiment tanks) to mimic vernal pools in order to teach the third grade students about ecosystems and scientific measurements. 

Graduate students Kennesha Bragg, Abigail Nelson, Joseph Morina, Andrew Kirk, April Harris, and Logan McDonald dug three mesocosms into place at the school. Small sticks from the surrounding area were placed in the mesocosms to encourage insects to perch, mate, and lay eggs.  Since students will measure the increase in the water depth from week to week as part of the project, the mesocosms were not filled.  And just in case the water levels fall low, rocks and sticks were placed in the mesocosms as an exit route for any amphibians that may need help escaping.

Five third grade classes, or approximately 100 students, heard a short presentation to give the students background information on mesocosm communities and explain the importance of vernal pools.  They learned what a mesocosm is, what they might find, and what their responsibilities will be for the project; they also got a chance to see spotted salamanders brought in by the graduate students. 

The classes were taken outside to view the mesocosms and given a brief demonstration on data collection.  Data will be collected weekly for a 7-week period, and the teachers then will help their students graph the data and compare the findings between classes. Students will sequence natural events chronologically, and classify species with similar characteristics into sets and subsets. The data they will collect will include water depth (measure of precipitation), water temperature, and biodiversity.

In addition, the graduate students constructed a field guide for students to use to identify species that may be present in the Dinwiddie area.

All of the graduate students involved are researchers at the Rice Rivers Center, with a diverse range of research from population ecology to microbial ecology. And while their research is vital to their work, they heartily support the Rice Rivers Center mission to promote outreach for environmental stewardship and education.

The goal of the event was to encourage the next generation of scientists to get started early and show them that opportunities for science are just outside the door.  “This was one of the most enjoyable experiences I have had as a graduate student,” said Bragg.

Norman T. Jeffries Jr. Memorial Stream Clean-up

May 19, 2016

On May 14, 31 volunteers joined Mark Jeffries in the Norman T. Jeffries Jr. Memorial Stream Clean-up. Created in memory of his father, the clean-up happened in Woodman Park, Henrico County, where a large amount of erosion has occurred on the stream bank and the riparian buffer has been lost. A significant amount of garbage and debris was removed from the stream, including tires and sheet metal. Stacey Heflin, Conservation Specialist assisted in water quality testing, and Alan Weaver, Fish Passage Specialist with the Virginia Department of Game and Inland Fisheries conducted an Aquatic Life Inventory using an electro-fishing device.

Lisa Turner, Rusty Sprouse and Mike Beck from the Society for Ecological Restoration at VCU introduced our volunteers to a method of stream monitoring using benthic macro-invertebrates. Benthic: meaning stream bottom; Macro: meaning large enough to see with the naked eye; Invertebrate: meaning has no backbone. A number of species were identified, including Damselflies, Dragonflies, Crayfish, Midge Fly Larvae, Lunged Snail, Scud (Amphipod), Caddisfly, and Beetle (Coleoptera).

The Norman T. Jeffries Memorial Stream Project adopted a 1-mile stretch of Hungary Creek in Henrico County through the Virginia Adopt-a-Stream Program; the group also adopted Woodman Park as a part of the Henrico County “Because We Care” program.

Special thanks were extended to the following people who provided educational assistance: Paul Bukaveckas, Ph.D. with VCU Dept. of Biology and Center for Environmental Studies; Drew Garey, Deputy Director of VCU Rice Rivers Center; Lisa Turner, Mike Beck and Rusty Sprouse from Society for Ecological Restoration at VCU; Alan Weaver, Department of Game and Inland Fisheries; Stacey Heflin, Conservation Specialist, Henricopolis Soil and Water Conservation District.

Lesley Bulluck, Ph.D. receives outstanding faculty mentor award

May 12, 2016

Dr. Lesley Bulluck, Assistant professor with the Center for Environmental Studies and Department of Biology at VCU, has been honored as a 2016 Outstanding Faculty Mentor. Her central research interests are population ecology and behavior of birds, and she is most often motivated by the ability to influence conservation and management.

For award nominations, undergraduate students were asked to select a faculty member who has made a lasting impression through their guidance and mentorship of undergraduates conducting research and scholarship at VCU. Denney Turner, UROP Research Fellow, selected Dr. Bulluck specifically for her efforts toward student engagement in research activities and experiences, her enhancement of student learning and research training in the discipline, and for her overall support and guidance. Turner states, “Working this past year with Dr. Bulluck has been nothing short of extraordinary. She opened my eyes to many different aspects of research. I have learned so much from Dr. Bulluck, the hands on experience alone was rewarding enough but working one on one with a professor that is so knowledgeable and passionate in their field was unbelievable. Working with Dr. Bulluck, I have broadened my knowledge of everything that goes into research. One can learn a lot in classroom-based education but working out in the field or lab, immersed in the subject can alter your thinking and conception. Overall, Dr. Bulluck helped me find my true passion this past summer. It has been a life changing experience that I am so thankful to have had with such a wonderful professor.”

At the Rice Rivers Center: VDH hosts minority health month event with Virginia tribes

May 9, 2016

On April 15 at the VCU Rice Rivers Center, the Virginia Department of Health’s Office of Minority Health and Health Equity (VDH-OMHHE) hosted an event celebrating April as Minority Health Month in Virginia.

The event began with a presentation of the signed gubernatorial proclamation by Secretary of Health and Human Resources, the Honorable William A. Hazel, Jr., MD. Dr. Hazel also made remarks about the importance of focusing on the health of all minorities in Virginia.

“For the three leading causes of death – heart disease, cancer and stroke – mortality rates in Virginia are 30 percent higher for blacks than they are for whites and 27 percent higher for all causes of death,” said Dr. Hazel. “The opportunity to be healthy is not equally available to all people living in all places in Virginia. It’s time we bring awareness to this injustice.”

The event continued with honoring two champions of equity in the tribal communities.  Elder Sharon Day of Minnesota, who also conducted a water ceremony at the event, is a nationally recognized health champion whose water walks around the United States highlight the link between health and nature. Narinder S. Arora, MD, is a pulmonologist practicing in Charlottesville, VA, who started the Healing Eagle Clinic on the Mattaponi reservation in King William, VA. He has travelled the 150 miles between his home and the reservation twice a month for the past 20 years in order to provide members of the tribal communities with medical care at no cost.

The event culminated in a listening session (similar to a town hall), which served as an open forum for Virginia’s tribal communities to discuss matters of health with leaders of various state agencies.

“This was a wonderful opportunity for government officials to interact with our state’s native tribes and hear the concerns they have about the well-being of their communities,” said Dr. Levine. “The listening session provided valuable insight on the concerns of Virginia’s tribal communities.  Having healthy, connected communities is one aim of Virginia’s state health improvement plan, the Plan for Well-Being. Having important discussions about health concerns, like the one we had today, opens the door for improving overall health for all Virginians.”

The theme for National Minority Health Month 2016 is “Accelerating Health Equity for the Nation.” The U.S. Department of Health and Human Services Office of Minority Health leads national minority health month efforts to raise awareness of the health disparities that continue to affect racial and ethnic minorities and how the country is working together to accelerate health equity.

Studying the Red Knot in Coastal Georgia

April 4, 2016

By Fletcher Smith, Center for Conservation Biology

The day will begin around six hours before high tide. Researchers will prepare enough food and water for the day ahead, and double check that all field gear is loaded up. The boat will drop into the water approximately four hours before high tide, and we will arrive on the island about three hours before high tide. The sand bars still expand for what seems like miles in every direction. This is the result of the up to nine-foot tides that characterize coastal Georgia. But as the water creeps up and the bars become smaller, the birds we are studying become more concentrated and much easier to access. By the time the tide reaches its apex, the birds will be in astonishingly huge concentrations, with upwards of 10,000 shorebirds (mixed flocks) occupying sand bars as small as one or two acres in size. But we are here to work with red knots, not the other shorebirds, and will focus our efforts on them during the mid-rising to mid-falling tide periods. 

The red knot is a robin-sized shorebird (and formerly called “beach robins”) that has two contrasting wintering strategies. A portion of the population will migrate to southern Argentina and Chile from breeding grounds in the high Arctic, while another portion will winter as far north as Virginia, all through the Caribbean and northern South America. When we arrive in Georgia in early April, the wintering population will be present, but the long distance migrants will not arrive until early May. We know all of this because a large percentage (around 5%) of red knots are individually marked with coded leg flags. These knots were captured in a variety of locations, from Delaware Bay to coastal Massachusetts (green flags), the breeding grounds in Canada and coastal stopover locations there (white flags), southern Chile (red flags), coastal Argentina (orange flags), and Brazil (blue flags). The majority of flags seen in April will be green (banded in the USA) but as the season progresses more of the long-distance migrants will arrive, displaying the full range of flags representing the above locations. This marked population makes studying arrival times, stopover duration, and population estimation easier than working with an unmarked population.  

This upcoming field season, our goals are to project a population estimate utilizing the coast of Georgia, map the important stopover locations, and attempt to increase the public awareness of red knots using the South Atlantic Coast of the US. During the 2015 field season, we saw peak numbers of red knots in the 7,000-8,000 range, and hopefully we will be neck-deep in knots again this year. 

This project is a collaboration among the Georgia Department of Natural Resources Non-game Division, U.S. Fish and Wildlife Service, U.S. Geological Survey, Manomet Center for Conservation Sciences, and The Center for Conservation Biology. Numerous other entities have assisted us in this multi-year project, including staff from Little St. Simons Island, St. Catherines Island, the U. S. Army Corps of Engineers, the Georgia Riverkeepers staff, and staff from Cumberland Island National Seashore. We will be relying on volunteer help from some of the best “resighters” out there, especially Pat and Doris Leary.    

This red knot resighting project is receiving funding from Gulf Power and Southern Company through their National Fish and Wildlife Foundation partnership. 

Ipswiches cope after Jonas

April 5, 2016

By Bryan Watts, Center for Conservation Biology 

On Friday, January 22nd the squeeze play between a rare winter tropical storm named Jonas moving north along the Atlantic Coast and a high pressure ridge over eastern Canada created battering winds within the mid-Atlantic.  By 3:00 a.m. on Saturday sustained onshore winds of 50 mph and gusts above 80 mph stood up offshore waves to a height of over 25 feet.  This storm caused widespread property damage across several states and reworked the landscape of the Virginia Barrier Islands.  A standing question for decades is how do resident birds that depend on this landscape cope with such storms?

Fall and winter storms are the agents of change within this dynamic barrier island landscape.  The forces of water and wind move tremendous volumes of sand overtop dunes and set back the successional clock.  Succession will begin anew, building dunes that lead to grassland, then to shrubland, and ultimately to maritime forest. This alternating process of damage and repair is critical to several breeding bird species, like the federally threatened piping plover and the declining least tern that depend on open beaches for nesting. But the season of residency for these breeding birds is opposite of the storms, with storms occurring in the fall and winter and breeding occurring in the spring and summer. Very little is known about how the winter bird community copes with these storms and their aftermath.

The Ipswich sparrow is a geographically isolated subspecies of the savannah sparrow. The Ipswich is a true coastal sparrow, spending its entire lifecycle in dune habitat along the Atlantic Coast. Its breeding range is restricted to Sable Island off the coast of Nova Scotia, Canada, where it nests in dune and heath habitat. Its primary winter habitat includes coastal barriers and beaches along the Atlantic Coast. The global population is estimated to be only 6,000 individuals. Although a considerable body of research has been completed on the breeding grounds, very little is known about the winter ecology of this unusual bird.

On January 30th, just seven days after the passage of JonasBryan Watts, Fletcher Smith, Ned Brinkley, and Todd Day traveled out to Metomkin Island to survey Ipswiches. Over the past several years, CCB has determined that Metomkin is the center of abundance for Ipswiches along the Virginia Barrier Islands (read about our visit to the island in the winter of 2014-2015). The site supports the largest contiguous patch of preferred habitat in the state. On this day we surveyed the 5.8-kilometer (3.6-mile) patch of habitat extending north from the south end of the island and recorded 115 Ipswich sparrows, 111 regular savanna sparrows, 12 horned larks, 10 northern harriers, 6 eastern meadowlarks and 4 lapland longspurs. Incredibly, the number of Ipswich sparrows counted is nearly identical to the 117 counted by Bryan Watts and Dana Bradshaw within the same patch in 2011.  

The trip to Metomkin offered a rare opportunity to examine barrier island habitats shortly after a major storm and to observe Ipswich response to changes. Despite the fact that the birds continued to be present on the island, their distribution and pattern of habitat use was dramatically different than during previous visits. In previous years, Ipswiches were mostly confined to the open dunes, overwash fans and hind-dune grasslands where the birds are easily camouflaged by their sand-colored plumage and foraged singly or in small groups. On this visit, most birds were compressed along the shrub line and were using dense vegetation.  

Upon inspection, it appeared that much of the grass and forb vegetation on the dunes and within the dune swales had been sand blasted, stripping and burying the seeds. It is possible that the entire year’s seed crop was lost in the storm leaving the birds to adjust and behave like their regular savanna cousins.  Maintaining flexibility and having a “plan B” may be the key to survival within this raw and dynamic landscape during the winter months.

Our Avian Heritage

April 1, 2016

By Bryan Watts, Center for Conservation Biology

Most students of natural history wonder about earlier times. Most of us are puzzle builders attempting to see a species in full relief. Over and over we place tiny fragments of information into a large, complex mosaic that we know will never be completed. We recognize intuitively that historical context is an essential part of that mosaic and we would give a great sum to sit down with a naturalist from an earlier time to ask questions that may fill in some of the gaps. How common was the species in their time? How did the species fit within the landscape? How did human use of the landscape influence distribution and abundance? How did earlier cultures view the species? In essence, we want to know how the ghosts of the past have led us to the present.

Sadly, much of what has been known about many of our species of conservation concern by earlier naturalists has been lost to time. We can read the formal writings of selected scientists who had the means and opportunity to publish some of their findings, but these are of course incomplete records. They frequently lack the detail that leads to the insights that we crave. Simple, mundane observations that seemed to the observer to be not even worth mentioning in publications are the jewels we seek. Some of this juice, this essence of context may be found in the observer’s field notes. Field notes are records of events or observations or thoughts made at the time of observation. They are accounts made for future reference.

Significant field records are being lost daily and with them potential insights into past conditions. Records that passionate field people have kept for decades are frequently discarded by family members at death. Family members that have never been self-ordained into the family of natural historians simply do not recognize the ongoing value of these records. They do not realize that for many of these people the records are held as their most valued possessions which they would protect to their last breath. Having carefully collected them during their most enjoyable hours, they would want them to live on and contribute to the knowledge of future naturalists.

More than ten years ago, CCB established the Avian Heritage Program, a project that is focused on preserving sets of historic field records for future generations. The program has a growing catalog of records. Donated and loaned sets of records are archived and scanned to be included in our digital library, and original materials are returned to the owner.

CCB is dedicated to preserving our avian heritage. If you have collected field records yourself or have those from a relative or friend and would like to have them preserved, please contact our office at info@ccbbirds.org or 757-221-1645.

At Home on the Islands

March 31, 2016

By Bryan Watts, Center for Conservation Biology

The Virginia Barrier Islands have been recognized for their extraordinary birdlife for centuries by the locals.  As word of this incredible place spread, waterfowl and shorebird hunters, bird collectors, researchers, and early photographers, flocked to the islands supporting a very early ecotourism industry by the late 1800s.  Early egg and bird collectors came from far and wide and today specimens from the area are distributed in museums throughout the world.  Olin Sewell Pettingill, the noted ornithologist and film maker from Maine, famously spent his honeymoon (no doubt to the excitement of his young wife Eleanor) in June of 1933 on Cobb Island photographing black skimmers and terns. 

Through all of this history, the source of the islands’ notoriety has been their support of large numbers of shorebirds and beach-nesting waterbirds.  The islands have never been touted for their support of breeding eagles.  Prior to the decline of eagles during the DDT era, only a single bald eagle nesting record was known for the island chain (a pair on Parramore Island).

Over the past decade as the bald eagle population within the Chesapeake Bay and along the Delmarva Peninsula has recovered, observations of eagles along the outer islands have increased dramatically.  Bryan Watts and Barry Truitt flew weekly shorebird surveys along the island chain during the 1990s.  During this time, recording three eagles along the 100 kilometers of open beach was a big day.  After 2010 it has been common to see 15 to 25 eagles of all age classes loafing along the beaches.  However, breeding eagles did not begin to colonize the islands in any numbers until after 2010, and in 2011 only three active territories were known.

The islands were recently surveyed by Bryan Watts, Mitchell Byrd, and Captain Fuzzzo as part of the 2016 bald eagle breeding survey.  Surprisingly, the crew mapped ten eagle nests on the islands including six in loblolly pines, two in small trees or shrubs, one on the ground in the dunes, and one on an old peregrine tower.  Ground nests are particularly rare in bald eagles except beyond the tree line in high latitudes.  Two ground nests have been documented on the islands in the past four years and these represent the first to be recorded along the Atlantic Coast. 

Adding bald eagles to the breeding avifauna of this rich landscape is in some ways unexpected.  Seeing them nesting among the dunes and standing in the surf extends our perception of their ecological boundaries.

Wild Bet on Woodpeckers Pays Off

March 30, 2016

By Bryan Watts, Center for Conservation Biology

It was 5 April, 2000 and we (Bryan Watts, Dana Bradshaw and Marian Watts) caught the 5:40 AM ferry across the James River and made the 30-minute drive south to take up strategic positions in the woods before 6:45 AM.  Just after dawn, woodpeckers began to emerge from their roost cavities calling and rallying together in the center of the cluster of trees.  We would count four on this morning, and over the next week an additional nine birds.  Thirteen plus two bachelor males within other sites were all that remained of their kind in Virginia.  Once relatively common and distributed throughout the southeastern part of the state, the red-cockaded woodpecker suffered dramatic losses with the exploitation of pines during the colonial expansion and much deeper declines with the movement toward the production of wood products through short-rotation pine plantations.  However, as recently as 1975, 60 different breeding sites were still known.  By 2000 nearly all of those sites had been milled and the population was perched on the edge of the abyss (read about the decline). 

The 1998 purchase of the Piney Grove Preserve, a 2,000+ acre stand of old pines, by The Nature Conservancy represented the final bet by an exasperated conservation community to save the species in Virginia.  The site was the last game in town and its purchase was made with a clear understanding of the long odds for success.  A coalition of the willing that included The Nature Conservancy, the Virginia Department of Game and Inland Fisheries, the U.S. Fish and Wildlife Service, and The Center for Conservation Biology formed with an initial objective of growing the population within the preserve.  The plan was to build a nucleus for recovery.

Despite the long odds, with the hard work of many, many individuals, the bet with Piney Grove Preserve has paid off.  During the winter of 2015-2016, CCB counted 68 woodpeckers within the preserve, an incredible five-fold return.  In just 15 years the conservation experiment has reversed a 400-year-old decline.  Although the acres of this initial purchase are now approaching their capacity for woodpeckers, other initiatives are pushing forward.  The purchase of several thousand acres of pineland (The Big Woods) adjacent to the preserve by the Virginia Department of Game and Inland Fisheries represents great promise for the future of pineland birds in the state.  The translocation of eight woodpeckers into the Great Dismal Swamp National Wildlife Refuge in October represents a second phase of recovery.  The Piney Grove Preserve has truly fulfilled its intended role as a nucleus for recovery.

Untangling dispersal in coastal peregrines

Natal dispersal is the movement of an animal from the place of birth to the location where it will ultimately breed.  For the majority of bird species, dispersal progresses through three phases including 1) a decision to leave the natal territory, 2) a transition that includes exploration or prospecting and 3) a decision about where to settle or establish their own breeding territory.  Of these three phases we know the most about when young birds leave their natal territories.  We know far less about prospecting and, for many species, even less about where young birds ultimately settle.  Famously, peregrine falcons have an extended and dramatic period of exploration (read about the wanderings of young peregrines from Virginia as revealed through satellite tracking conducted by CCB).  They are named for their wide peregrinations.  In stark contrast to these extensive wanderings when it comes to establishing breeding territories they actually settle relatively close to their natal sites.

For more than two decades, a large portion of the peregrine falcons produced in eastern North America have been marked with two bands including a United States Geological Survey (USGS) aluminum band with a numeric code and a field-readable band with unique combinations of letters and numbers.  In most instances reading the USGS band requires that the bird be captured.  However, the field-readable band may be read using spotting scopes, binoculars, or cameras.  The use of these bands has allowed the community of biologists (and the public) to resight these birds over time and to contribute a great deal to what we know about their spatial ecology and natural history.

Since the early 2000s when Shawn Padgett pioneered the use of video cameras on nests to read bands, CCB and other groups have used camera traps to identify breeding adults.  This activity has opened up the possibility of addressing a long list of questions, including how long peregrines live (read about James, the longest living wild peregrine known), the degree of relatedness within the breeding population (we have documented close inbreeding between siblings and parent-offspring pairings), lifetime reproductive success, and patterns of dispersal, among others. 

Like many other raptor species, dispersal serves to reduce the likelihood of pairings between parents and offspring.  In addition, differences in dispersal distances between males and females makes pairings between full siblings less likely.  Dispersal distances documented by CCB and partners within coastal Virginia range from 4 to 207 km for males (median of 24 km) and 0 to 473 km for females (median of 105 km).  The banding and resighting efforts in Virginia are building an integrated database that is beginning to untangle several aspects of peregrine ecology that have been notoriously difficult to address.

Anne Wright, director of outreach education, receives Green Giant Award

March 22, 2016

Anne Wright was awarded the Green Giant Award by the Sierra Club Falls of the James Group this month in honor of her work in environmental education.

“We are happy to recognize Wright for her hard work in local environmental education,” said Adele Maclean, chairperson for the club. “She has brought attention and enthusiasm that has been truly inspirational to all of us with the Science in the Park program.”

Wright’s projects and students were featured in the short documentary “The Urban Forest,” which was honored at the recent RVA Environmental Film Festival.

The award is given annually to individuals who have demonstrated “outstanding commitment to protecting and improving the environment of greater Richmond.” Wright was presented with the award during the chapter’s March 9, 2016, meeting, during which she spoke about the game camera project currently underway in the James River Park System.

“Wright has been instrumental in encouraging students to learn and share their knowledge about local ecosystems,” said Scott Burger, coordinator of the film festival and FOJG, which is one of 14 Sierra Club chapters in Virginia.

The motor of our small fishing boat hums as we travel up a stream bisecting a narrow peninsula of red mangrove forest called Bocas del Atrato, in a remote region of the Caribbean coast of Colombia. We glide past massive mangrove prop roots and lush foliage, and come to stop along a patch of terra firma. A Common Black Hawk eyes us warily from an overhead perch as a chorus of howler monkeys lends an ominous feeling to the dawn. I ready my clipboard for a standardized bird survey and set my stopwatch for 10 minutes. It’s not long before I see a flash of brilliant yellow, and hear the distinctive chip note of a Prothonotary Warbler. I’ve followed this species from its temperate summer breeding grounds to its wintering habitat in the Neotropics, where I hope to unravel some of the mysteries of its poorly known winter ecology.

During the summer, Prothonotary Warblers are found in forested wetlands throughout the eastern U.S. and southern Canada, including at VCU’s long-term study site in the Lower James River Important Bird Area. For the winter months, Prothonotaries migrate to Central and northern South America, where highest concentrations are found in coastal mangrove forests. With funding from the Riverbanks Conservation Support Fund and the Northern Neck Audubon Society, I traveled with Alessandro Molina (B.S. Biology, VCU ‘14) and Dr. Lesley Bulluck on a month-long expedition to study Prothonotary Warblers overwintering Colombia. There we partnered with Dr. Nick Bayly and Angela Caguazango from SELVA: Research for Conservation in the Neotropics, a Colombian non-profit research institute with a focus on migratory bird ecology. Our goals were to conduct density surveys to determine where the birds are most abundant, to capture birds and collect feather samples, and to quantify habitat associations.

Our trip spanned over 700 miles of the Caribbean coast. We visited four mangrove forests and one freshwater lagoon, conducting a total of 70 density surveys and collecting 115 feather samples. As we traversed between sites, the humid lowland forest on the border of Panama transitioned to dry tropical forest in the east, where the landscape was peppered with cacti. Our expedition was a success, not only in terms of the data we collected but also through the connections we made to local people and places. Guides from the community shared their knowledge of local flora and fauna, and biologists from the Sistema de Parque Nacionales Naturales told us about their conservation successes and challenges. Leaving Colombia’s rich avifauna and welcoming culture was bittersweet, but almost as exciting as collecting the data will be understanding the story it can tell us. Working with my graduate thesis advisor Dr. Bulluck, I will analyze isotope ratios in the feathers we collected, which will help determine how populations are geographically linked between seasons. Ultimately, we hope to use our increased knowledge of Prothonotary Warbler ecology to inform management strategies and promote full life-cycle conservation, a goal which will certainly be advanced by the partnerships we made during this expedition. 

Tracking Red-cockaded Woodpeckers through winter and their recovery

March 22, 2016

VCU Rice Rivers Center and The College of William & Mary's Center for Conservation Biology

This winter marked the Center’s 12th year of conducting the annual winter survey of the red-cockaded woodpecker population at the Nature Conservancy’s Piney Grove Preserve. We monitor the population of red-cockaded woodpeckers by conducting a full census of all individuals in the spring just before the breeding season and again during the winter. We also monitor all nesting activity in the early summer.  Because every bird in the population is color banded as nestlings, we can follow the movement of individuals between breeding groups, assess their survival, and determine their breeding behavior. The winter survey provides an opportunity to examine how the autumn-winter period influences survival patterns and document the dispersal of adults and summer fledglings. 

During the winter of 2015-2016, we recorded the highest number of red-cockaded woodpeckers in decades with 69 individuals distributed among 14 groups. Red-cockaded woodpeckers are cooperative breeders so groups may contain the breeding male and female, as well as additional birds that assist with incubating and feeding young. These groups will remain together throughout the entire annual cycle and travel together daily for foraging even in winter. The Piney Grove population continues to grow every season as the winter survey has shown through time, with 29 birds detected in 2002, 45 birds in 2011, and 57 birds as recent as 2013.  Among the birds detected this past survey included 16 of the 21 birds fledged in 2015. We typically lose 50-75% of the recently fledged birds by winter so the number of birds remaining bodes well for new recruitment into the 2016 breeding population.      

The Nature Conservancy’s Piney Grove Preserve has been the nucleus of recovery in the state since the early 2000s when the Commonwealth’s population of woodpeckers sank to an all-time low. A multi-organizational partnership that includes the Nature Conservancy, The Center for Conservation Biology, the Virginia Department of Game and Inland Fisheries, and the U.S. Fish and Wildlife Service, has worked together on habitat and population management to bring the number of red-cockaded woodpeckers back from the brink.  

Tracking and training on Chiloe Island, Chile

March 22, 2016

VCU Rice Rivers Center and The College of William & Mary's Center for Conservation Biology

by Fletcher Smith

Several species of shorebirds make truly epic journeys, flying non-stop from Alaska to New Zealand (6,835 mi) or from Atlantic Canada to Brazil (4,350 mi). These journeys are fueled by stores of fat built up during migration stopovers or on wintering staging areas. One of the most powerful migrants in the Western Hemisphere is the Hudsonian godwit. The godwits are comprised of three disjunct breeding populations, one in Alaska, one in the Mackenzie Delta, and one in the Hudson Bay Lowlands. These high-latitude nesting birds make epic non-stop flights from the breeding grounds to stopovers in the Amazon and Orinoco river basins, then continue on to wintering locations in Argentina and Chile.   

The world of shorebird biologists is very small. There are probably only hundreds of biologists that study these fascinating creatures in the entire Western Hemisphere. I had the good fortune of talking to a Chilean colleague about satellite tracking of shorebirds at a professional meeting, and that discussion led to a trip to the island of Chiloe, located in the southern Pacific Coast of Chile. The primary goal of the trip was to assist local biologists in tagging of Hudsonian godwits with satellite transmitters and potentiall to train them to tag other shorebirds in the future. In total, five godwits were tagged during the trip, all within the Quinchao Island on a high tide roost near Chullec. The primary goals of this project are to determine winter territory size of godwits and to determine the various sites that are used for foraging and roosting. This information will be used to protect any unknown high-use sites for the godwits. 

The results of the tagging are filtering in, and some surprising movements are being recorded. Shorebirds tend to have high site fidelity to feeding and roosting sites in winter, but their movements in-between tides are not well documented. The rugged and remote Chiloe coastline makes fieldwork particularly difficult. At least two of the godwits appear to be making large flights to feeding sites 40-50 miles away, or are moving during the winter to better foraging sites. More data is needed to decipher their winter flight patterns, but all five transmitters are sending data on movements and roost sites and we should know more in another couple of months.      

The tracking of Hudsonian godwits is a collaborative effort between ConservaciÓn Marina and The Center for Conservation Biology. The success of the trapping efforts was due to the intense scouting and long-term shorebird counts that Luis Espinoza and Claudio Delgado performed prior to my arrival.  

Master's students present at research society meeting

March 21, 2016

Master’s students Dana Devore and Spencer Tassone presented the results of their thesis research at the March 11 Atlantic Estuarine Research Society meeting.  Devore has been working on the Mountains to the Sea project, which is a collaboration among VCU’s Center for Environmental Studies at the Rice Rivers Center, Randolph-Macon College, Washington & Lee, and the United States Geological Survey. Tassone has been analyzing the continuous water quality monitoring data from the Rice Rivers Center pier to better understand the oxygen metabolism of the James. 

Below is the abstract from Devore’s research:

The Effects of Tidal Forcing on Nutrient Fluxes in the Tidal, Freshwater James River Estuary, VA

Dana Devore, Virginia Commonwealth University Center for Environmental Studies
Dr. Paul Bukaveckas, Virginia Commonwealth University Center for Environmental Studies and Department of Biology

A 12-month study (January to December 2015) focused on the effects of tidal forcing on nutrient fluxes in the tidal, freshwater segment of the James River Estuary (JRE). Discrete sampling of nutrient chemistry and continuous monitoring of tidal discharge were used to determine the volume and timing of the tides, differences in nutrient concentrations between incoming and outgoing tides, and associated nutrient fluxes. The goal of this study was to improve understanding of tidal influence on nutrient fluxes and their role in nutrient transport to the lower estuary.  Our results show that differences in nutrient concentrations between incoming and outgoing tides were small throughout the year.  This finding suggests that nutrient fluxes at the tidal fresh-oligohaline boundary are determined by tidal volume, not gradients in concentrations.   We analyzed changes in water quality during seaward and landward tidal excursions to infer biogeochemical processes.  Differences in oxygen production and nitrate utilization suggest greater autotrophy during landward excursions, consistent with more favorable light conditions.   This work was conducted as a collaborative effort among VCU Center for Environmental Studies at the Rice Rivers Center, Randolph-Macon College, Washington & Lee University, and the United States Geological Survey, participating in the “Mountains to the Sea” project.

Below is the abstract from Tassone’s research:

Estuarine metabolism and zooplankton dynamics in the tidal freshwater segment of the James River

Spencer Tassone, Virginia Commonwealth University, Department of Biology
Paul Bukaveckas, Virginia Commonwealth University, Center for Environmental Studies and Department of Biology

Utilizing daily dissolved oxygen data from a fixed station within the tidal freshwater James River Estuary, VA we examined seasonal and interannual trends in primary production, respiration and net ecosystem metabolism (NEM). Results show that this segment of the James River is net autotrophic on an annual time scale with peak NEM occurring during March-November. Annual mean NEM ranged from 0.8-1.2 g O2 m-2 d-1 with previous studies in Chesapeake Bay reporting ranges from -5.6-0.5 g O2 m-2 d-1. Annual mean production rates were within the same range as previous studies of Chesapeake Bay (5.8-7.5 vs. 5.2-8.9 g O2 m-2 d-1) however respiration rates were lower (2.4-3.2 vs. 4.7-12.3 g O2 m-2 d-1). Dominant zooplankton in this segment were the copepod Eurytemora affinis, the cladoceran Bosmina longirostris, and the rotifer Brachionus calyciflorus. Patterns in zooplankton abundance were then, in some cases, related to NEM along with water temperature and water replacement time. These results provide evidence that the tidal freshwater segment of the James River is among the most productive sites within the Chesapeake Bay Estuary and that high rates of metabolism may in turn influence production at higher trophic levels.

Autochthony, allochthony and the role of consumers in influencing the sensitivity of aquatic systems

March 21, 2016

The VCU Rice Rivers Center congratulates Drs. Joseph D. Wood, David Elliott, Greg Garman, and Stephen McIninch, and Paul Bukaveckas, as well as Messrs. David Hopler, William Lee and Aaron J. Porter on their publication: ”Autochthony, allochthony and the role of consumers in influencing the sensitivity of aquatic systems to nutrient enrichment”, published in Food Webs.

The abstract reads as follows:

Primary consumers may mitigate or exacerbate the effects of nutrient enrichment by grazing on plant matter and recycling nutrients.  Few studies have quantified these effects for a suite of consumers and in the context of other processes regulating plant standing crop and nutrient supply.  We quantified the abundance, feeding and diet of zooplankton, benthic filter-feeders, and planktivorous and detritivorous fish in the James River Estuary and found that consumer-mediated fluxes of CHLa and N were small in comparison to other fluxes regulating phytoplankton abundance (production, respiration, advection) and N availability (external inputs, internal recycling).  Chlorophyll-a ingestion by consumers was equivalent to 15% of daily phytoplankton production and N recycling by consumers corresponded to 29% of phytoplankton N demand.  The bulk of phytoplankton production (74%) was lost to autotrophic and heterotrophic respiration.  Recycling of N contained in autochthonous and allochthonous organic matter was sufficient to meet 100% of phytoplankton N demand with external inputs corresponding to 39% of phytoplankton N demand.  Experiments using 2000 L outdoor mesocosms with natural plankton communities showed that the presence of consumers (shad) resulted in higher N availability, elevated CHLa and reduced macrozooplankton abundance.  Overall, our study showed that the direct effect of consumers on fluxes of CHLa and N was small as the bulk of phytoplankton biomass and N passed to microbial decomposers.  However selective grazing by planktivorous fishes reduced zooplankton densities resulting in greater phytoplankton yield at lower nutrient concentrations.

Virginia Oyster Shell Recycling Program adds collection sites in Hampton Roads, Central Virginia

March 17, 2016

The Virginia Oyster Shell Recycling Program, a collaborative program of the VCU Rice Rivers Center, is adding new partners to make it even easier for the public to recycle shells. Harris Teeter, LLC of Matthews, North Carolina and Sam Rust Seafood, Inc., of Hampton, Virginia will support public drop-off locations at 17 Harris Teeter stores in Virginia starting March 21, with oyster shells dedicated to restoring oyster habitats in the Virginia portion of the Chesapeake Bay.

"This is a wonderful opportunity to demonstrate that partnerships are the key to bay restoration,” said Len Smock, Ph.D., director of the VCU Rice Rivers Center.

The new shell drop-off locations, which span from Virginia Beach to Charlottesville along the Interstate 64 corridor and include Suffolk, Portsmouth and Chesapeake, will help ensure shells are returned to the Chesapeake. The program is actively recycling shells in Charlottesville, Richmond, Hampton, Newport News and Lancaster County and collected more than 60,000 pounds of shells in 2015. The public can visit participating Harris Teeter’s seafood departments to drop off their used shells.

“We are extremely proud to partner with Sam Rust and VCU Rice Rivers Center to offer the Virginia Oyster Shell Recycling Program to our customers,” said Danna Robinson, Harris Teeter’s communication manager. “Harris Teeter’s commitment to sustainability has long included sourcing seafood from local fishermen who practice and support responsible fishing and sustainable management of our rivers and oceans. The VOSRP will allow us to further strengthen our environmental commitment to properly maintain local waters.”

Sam Rust Seafood has focused on local and regional seafood since the inception of the company more than 75 years ago.

“It’s in our DNA,” said David Nichols, sales manager for Sam Rust Seafood. “We consider it a privilege to be a local, family-run business that supports the many products coming out of the waters that are in close proximity to the area where we all live and work. Sustainability may be a new buzzword to many of us. However, it has always been what we are all about.”

Oyster shell recycling provides local businesses and residents the opportunity to promote the protection and remediation of the Chesapeake Bay by becoming involved in the restoration of wild, native oysters. Recycled shells are used to create a natural hard substrate to which new oysters can attach.

“The Virginia Oyster Shell Recycling Program and the VCU Rice Rivers Center are working to turn the remnants of yesterday’s roast into tomorrow’s reefs.”

Oysters create their own habitat and provide physical, chemical and biological benefits. As filter feeders, oysters filter up to 50 gallons of water per day by filtering phytoplankton, suspended sediment and nutrient pollution. This filtering capacity plays a significant part in the clarity of the water column, allowing aquatic grasses to grow and provide critical habitat for young fish and crabs.

“This innovative, public-private partnership is a testament to the bay’s incredible ability to bring people together. Thanks to this exciting collaboration, oyster lovers can donate shells more easily and support the Chesapeake Bay,” said Molly Ward, Virginia secretary of natural resources. “The Virginia Oyster Shell Recycling Program and the VCU Rice Rivers Center are working to turn the remnants of yesterday’s roast into tomorrow’s reefs.”

Todd Haymore, secretary of agriculture and forestry, said the partnership will enhance Virginia’s reputation in the oyster market.

“As the oyster capital of the East Coast and the third-largest seafood producer in the nation, Virginia stands to gain significantly from a program such as this that will increase the wild oyster population, which benefits both the health of the bay and Virginia’s watermen,” Haymore said.

Morina addresses Chesapeake Bay Foundation group

May 8, 2015

On February 25, VCU’s Joe Morina addressed the Chesapeake Bay Foundation’s “Desserts and Discussion” group, elaborating on the importance of wetlands to clean water. A graduate student in VCU’s Biology Department, and Virginia Sea Grant Graduate Research Fellow, Morina gave a talk entitled, “Wetlands: Historic Trends and Future Perspectives”. He shared information on wetland ecology, wetland loss, and wetland response to climate change, underscoring the importance of wetlands to everyday life, and why we need to preserve and restore these ecosystems.

Society for Ecological Restoration launched at VCU

March 16, 2016

In January, graduate students in the Center for Environmental Studies and Biology at VCU collaborated to create a new VCU student association centered on the theme of ecological restoration. Dubbed SER@VCU, the group is now an official student chapter of the Society for Ecological Restoration, an internationally-recognized leader in promoting the practice and advancement of ecological restoration.

SER@VCU is the eleventh student association to form worldwide and the first in Virginia. Through organizing workshops, lectures and discussions, documentary screenings, field trips, and initiating both short- and long-term restoration projects, SER@VCU hopes to foster undergraduate and graduate student interest and education in the field of restoration ecology, promote skills and experience acquisition for students and community members, and facilitate networking between researchers, practitioners, and students in the mid-Atlantic region.

At the regional SER Mid-Atlantic chapter conference on March 14-15, VCU graduate students Melissa Davis and Joseph Morina, as well as undergraduate senior Christopher Gatens, presented original research from the ongoing wetland restoration project at the VCU Rice Rivers Center. Gatens received the special honor of first prize for his poster documenting an ongoing historic tree stump and wetland community modeling study at the Rice Rivers Center.

It was the first time representatives from VCU have presented research at the conference, and was an excellent opportunity to represent VCU and the Rice Rivers Center within a major organization in the regional restoration community.

Black-bellied plovers tracked to wintering grounds

March 3, 2016

VCU Rice Rivers Center and The College of William & Mary's Center for Conservation Biology

The Center for Conservation Biology, in partnership with the Canadian Wildlife Service, has tracked black-bellied plovers from their Arctic breeding locations and fall stopover locations to their wintering grounds.  The plovers were trapped on the breeding grounds at Polar Bear Pass National Wildlife Area, located on Bathurst Island, Nunavut Territory, as well as at Mingan Archipelago National Park Reserve, located in the Quebec Province along the St. Lawrence River.

The current locations of the tracked plovers are spread across a wide zone of the Caribbean and Central and South America.  This wintering strategy contrasts with whimbrels that were tracked using similar satellite tags, with the majority of those birds concentrated in a relatively small area of Brazil. Black-bellies have a more generalist approach to habitat and diet than most shorebirds, and this may help explain why they are not concentrated in one area of the tropics and occupy such a broad latitudinal and longitudinal gradient in winter.    

Several interesting migration tracks were recorded, including a non-stop transoceanic flight from Newfoundland to Brazil, with the plover making the 3,462 mile (5,570km) flight in approximately five days.  A long-distance land route was also recorded, with the bird flying nearly six days and 3,960 miles (6,373km) from the high arctic breeding grounds to the wintering grounds in Cuba.  The migration route of the plover tagged on Mingan Archipelago is interesting in that it provides evidence that at least some of the Atlantic Coast flyway shorebird populations utilize wintering grounds on the Pacific Ocean, in this case the well-documented shorebird hotspot of the Bay of Panama.

The high arctic nesting plovers appear to have several migration strategies.  Several staged near the breeding grounds, then flew non-stop to winter locations.  Several also migrated from breeding grounds to Atlantic Canada stopover locations before departing to winter locations.  One of the tagged plovers was likely lost over the ocean due to interaction with a tropical storm system. 

Black-bellied plovers are one of the smallest birds that can be tracked using current satellite tracking technology.  Recent technological advances have reduced the size of satellite units, and this promises to answer life-cycle questions on even smaller migratory species.   

The tracking of black-bellied plovers is a collaborative effort between The Center for Conservation Biology and the Canadian Wildlife Service, who initiated the tracking in 2014. Logistical support for the Bathurst Island field expedition was provided by the Polar Continental Shelf Program in Resolute, Nunavut. The tracking of the plovers is an ongoing project and the birds can be followed at Seaturtle.org.

The Center for Conservation Biology is a partnership between VCU Rice Rivers Center and The College of William and Mary.

Ecology in Motion at the Science Museum of Virginia

February 25, 2016

On Friday, February 19, The Science Museum of Virginia hosted Ecology In Motion, a free, interactive and educational event with the Richmond Ballet’s Minds In Motion. Community organizations exhibited, including the VCU Rice Rivers Center, in an effort to bring a spotlight onto ecology, conservation and native plants.

A variety of interesting, hands-on displays from ten different Richmond organizations were available to the visitors, each with materials packed full of useful information to take home.  In addition to the Rice Rivers Center with Dr. Art Evans, the community partners included Lewis Ginter Botanical Garden, Maymont, Pocahontas Chapter of the Virginia Native Plant Society, Tricycle Gardens, The Richmond Audubon Society, Chesapeake Bay Foundation, James River Park System, Virginia Master Naturalists, and Virginia Natural Heritage Program.

The event ended in the evening with a performance by Minds In Motion Team XXL performing “Journey of the Monarch Butterfly”, a dance depicting the incredible life cycle of the Monarch. Following the performance, Doug Tallamy, Ph.D., author of Bringing Nature Home, presented a lecture, “Why should you consider planting native?”.

Dr. Tallamy’s visit to Richmond was underwritten by VCU Biology, whose students enjoyed lunch and a lecture entitled “Are Introduced Plants ‘Bad’?”. Many thanks to the ASPIRE students from VCU who helped to make the evening possible with their extensive volunteer efforts.

2016 Eagle Survey - Public participation requested

February 17, 2016

VCU Rice Rivers Center and The College of William & Mary's Center for Conservation Biology

Countdown begins for historic 2016 eagle survey – You can help:

Incubation is underway for many bald eagle pairs throughout the commonwealth and in less than two weeks the 2016 Virginia Bald Eagle Survey will begin. 2016 represents the 60th year of the survey initiated by Jackson Abbott and volunteers of the Virginia Society of Ornithology. In addition to this incredible milestone, this survey represents the 40th year of Mitchell Byrd’s tenure and the 25th year of Bryan Watts’ tenure conducting the survey. The survey is expected to take 150 hours of flying, will cover more than 1,000 nests, and is planned to be a five-year update for many areas not covered since the 2011 survey.

The Virginia Bald Eagle Survey is a national treasure. The survey has become one of the most significant serial data sets in the world. More than population information alone, the effort has produced a wealth of ecological information on a population recovering within an increasingly human-dominated landscape. It has become one of the best records of arguably the greatest conservation accomplishment in our nation’s history. Since 2009, results of the survey have been made available on CCB’s website via an interactive mapping portal where users are able to view known nest locations throughout the state. The web application receives more than 30,000 visits per year and has become a critical resource for land planners.

We are requesting your participation in this benchmark survey. The annual aerial survey covers the Coastal Plain including the tidal reach of the Chesapeake Bay, the Eastern Shore, and lower Tidewater. We rely on the eyes and ears of the public to document the distribution of breeding eagles in other areas of the state. If you know of eagle nests in your area, please visit the Eagle Nest Locator in our mapping portal to see if they are known to the survey. If not, please report your observations to info@ccbbirds.org and contribute to this historic survey. For more information, visit our Report a Nest page.

 

The 2016 survey is being sponsored by the Virginia Department of Transportation, the National Park Service, Dominion, the U.S. Department of Defense, the U.S. Fish and Wildlife Service, the Army Corps of Engineers, and The Center for Conservation Biology. We thank all of these organizations for their commitment to eagle conservation in Virginia.

 

Eagles rarely gamble during the breeding season

January 12, 2016

VCU Rice Rivers Center and The College of William & Mary's Center for Conservation Biology

By Bryan Watts

The date is March 5th, 2005 and we are flying an eagle survey on the upper Rappahannock River in the Chesapeake Bay.  From the river, fingers of water reach out across the land ending in serpentine forests that wind their way through open farm fields.  As we fly up one of these drainages a familiar pattern appears.  Beavers have built a series of dams interrupting the ribbon of forest.  I count eight dams in succession.  From above, the ponds look like terraced rice patties in the mountains of China or Thailand.  Standing along one of the dams is a lone pine tree that supports a huge eagle nest.  We glide low over the nest and see that the female is incubating but fast asleep with her head down.  In the nest next to her is the distinct auburn hair of a muskrat glowing in the sunlight.  Despite the idyllic scene, the female is on borrowed time.  The nest tree is completely dead, having succumbed to rising water.

Eagle nest trees die regularly in the Chesapeake Bay.  Due to their large size and position on the landscape, nest trees are particularly vulnerable to lightening strikes but are also killed by water, disease, and insect pests.  Once dead, the trees progress through a predictable series of changes.  The bark sloughs off, they lose their lateral limbs, and finally either the crown is broken out or the entire tree snaps off at the base.  Within three to five years, most dead pine trees have lost their crowns or are on the ground.  By then, most eagle pairs will have moved on.  Eagles are not risk takers when it comes to using nest trees.

Despite the fact that nest trees die and topple over every year, the loss of a breeding attempt to tree failure is extremely rare for eagle pairs in the Chesapeake Bay.  Of more than 10,000 breeding attempts that have been monitored in Virginia since 1962, only one in 850 failed due to tree loss.  Nearly half of these losses were due to violent storms that snapped off live trees during the nesting period.  Of the remaining losses, nearly all were in trees that had been dead only one year.  The median time that pairs continue to use nests following nest tree mortality is one year, but the average is just less than two years.  Birds that lost breeding attempts when dead trees were blown down are the exception when pairs have hedged their bets a bit too far.  As a rule, eagle pairs nesting in the Chesapeake quickly pull up roots and move on when their nest tree is killed.  

Moving Woodpeckers

January 7, 2016

VCU Rice Rivers Center and The College of William & Mary's Center for Conservation Biology

By Bryan Watts

The stars had just bloomed over the pines as I climbed forty feet up into a tree to replace a cavity screen.  Pleiades had emerged from the distant glow of the Norfolk skyline and was sailing north.  Standing in the tree with all the lights off, I was suspended between the black void of the swamp below and the brilliant sky above.  After more than a decade of wishful thinking and months of planning, preparation, and paperwork, the move was finally underway.  Teams of biologists from across five states had been set in motion to capture and move woodpeckers.  Later this night they would converge on the Great Dismal Swamp National Wildlife Refuge in a historic effort to establish a new population of the federally endangered red-cockaded woodpecker.  

Bryan Watts climbs into pine tree to replace cavity screen

Virginia supports the northernmost population of red-cockadeds.  Because the single, small population located within the Piney Grove Preserve is vulnerable to catastrophic events, the Virginia Recovery Plan has long called for the establishment of additional populations.  If successful, the Dismal Swamp population would represent a milestone in the recovery of the species around the northern periphery of its breeding range.  

Making Preparations

Preparations for the move have been years in the making and included habitat management, site selection, cavity installation, work with donor populations, and identification of candidate birds. 

In recent years, staff of the Great Dismal Swamp National Wildlife Refuge has been working to prepare habitat to support the woodpeckers.  During the summer, biologists delineated eight forest areas that would receive the birds and hopefully support breeding territories into the future.  Students with the AmeriCorps program would do some of the heavy lifting and cut trails through swamp vegetation into selected sites.  Late in the summer, Bobby Clontz and Tim Sanjule from The Nature Conservancy installed artificial cavities in four pines within each of these eight locations.  The introduced birds will use the artificial cavities for roosting until they are able to excavate their own natural cavities.  In the week running up to the move, we “cleared” the artificial cavities and placed a screen over each entrance to insure that no interlopers would be inside when the birds were placed. 

The woodpeckers were scheduled to be taken from two “source” populations, including Carolina Sandhills National Wildlife Refuge near McBee, SC and Palmetto-Peartree Preserve near Columbia, NC.  Birds within both populations had been monitored during the spring breeding season and individuals were color-banded for later identification.  Late in the summer, individual males and females were identified as candidates for the move based on the spring production figures. 

In early September, teams of biologists converged on donor sites to locate designated candidate birds and to determine where they were roosting.  On 21 October, just days before the actual move, teams of biologists convened onsite once again to relocate birds in preparation for the move.  Over the next two days, target and backup birds were identified and “roosted” to facilitate capture and to insure that everything was fully prepared for move day.         

After all of the target birds, backups, and backups to backups had been roosted within the donor populations, Will McDearman, the national recovery coordinator and commander of the move, gave the green light.  The move was scheduled for Thursday night, the 23rd of October, and would involve more than 35 people from multiple agencies and organizations.

The Move

Woodpeckers would be captured just after they entered their roost cavities at dusk, placed in custom carrying boxes, driven north, and then placed in new cavities to be released into their new habitat at dawn.  Eight birds in total including four hatch-year males and four hatch-year females would be moved.  One male and one female would be taken from Palmetto-Pairtree Preserve and the remaining birds would be taken from Carolina Sandhills.

The declaration by McDearman would set in motion orchestrated capture plans within the donor sites and placement plans within the swamp.  On the afternoon of 23 October, Nancy Jordan, woodpecker biologist for Carolina Sandhills and field general for the South Carolina operation, would rally the troops, break them into ten teams, and deploy them to their assigned locations.  Jan Goodson would do the same in North Carolina.  By late afternoon, teams were in position and waiting for target birds to roost.

Efforts were focused on the safe capture of the target birds.  As birds entered roost cavities, net handlers moved to the base of roost trees, raised nets on telescopic poles to cavities, and enticed birds out into nets.  Birds were removed from nets and their identities were confirmed by reading their bands before they were placed in carrying boxes.  Within an hour and a half after sunset, radio communication would confirm that all eight birds were safely in hand leading to a collective sigh of relief across three states. 

Capture teams geared up and prepared for the long convoy north to the Great Dismal Swamp where they would rendezvous with additional teams in the refuge bunkhouse.  All birds were assigned to specific cavity trees and teams had been assembled to place them into artificial cavities.

The North Carolina team, including Matt King and Jaan Kolts, made their arrival by 9:30 PM and were quickly dispatched on the forty-five minute drive through the swamp to recruitment cluster YCC1.  With assistance from a Virginia crew they used Swedish climbing ladders to climb trees and placed the male in cavity 03 and the female in cavity 04.  Screens were tacked over the entrances to hold the birds in cavities until “release” the following morning.  Climbing ladders were broken down and moved to other sites to be used later in the night.

The South Carolina teams pulled into the bunkhouse parking lot just after 2:00 AM.  Placement teams were assembled and convoyed out to the three remaining recruitment clusters.  Birds were placed in their assigned trees and screened in by teams working simultaneously and all birds were safely in place by 3:45 AM.  Shanghaied from their natal territories, they would now have less than four hours of sleep before being released into a new site.

The Release

Release of birds into new environments is an exciting event and the young woodpeckers were released into the swamp by simply pulling cords to remove the screens.  Red-cockadeds in Virginia typically emerge from cavities around official dawn, which on this day was 7:20 AM.  Release teams were deployed from the bunkhouse by 6:15 AM and were in place within the woods by 7:00 AM.  Teams consisted of screen pullers and observers with the objectives of safely releasing the birds, observing their behavior, and minimizing disturbance.

All of the birds flew strongly out of cavities and were calling when released.  The female released in cluster C3 flew directly up into the crown of an adjacent tree and began foraging and calling to make contact with other birds.  She then foraged through the trees in an arc around the cluster and was joined by the male in the third tree she visited.  Both birds were calling and foraging when the team left them after twelve minutes.  Walking out of the woods after a long night, all of the teams were excited to have seen the birds interacting with their new habitat.

Follow-up Status

Following release on the morning of 24 October, the birds were left to settle in for more than a month with no human contact.  They were left to their own devices to stay or go, to choose their own relations, their own recruitment clusters, their own roost cavities, and to define their home ranges.

On 10 December, a team lead by Mike Wilson and including Bart Paxton, Fletcher Smith, and Kelly Morris, would begin a systematic assessment of the birds that remained in the swamp.  Over several days they would move through each cluster to see if birds emerged from cavities at dawn or entered at dusk.  They would use spotting scopes to read color-band combinations in order to identify all birds associated with clusters.

Although the birds had shuffled locations and relationships, six of the eight birds released on 24 October remained within recruitment clusters.  This includes four females (all of those released) and two males.  The sole male moved from North Carolina was absent and one of the males from South Carolina was not found.  A promising sign was that one of the remaining males was roosting in a cluster with two females and the other male was joining up and foraging with a solitary female. 

Spotting Red-cockaded Woodpeckers

The Future    

With the successful release of eight birds into the Great Dismal Swamp National Wildlife Refuge and the retention of six of these birds, including two potential pairs, a decade of wishful thinking was concluded.  However, success will be measured in the future by the establishment of stable and productive breeding sites.  We remain hopeful and will be watching this spring.

Regardless of what happens in the future, the successful translocation of woodpeckers from donor sites in the Carolinas to the Great Dismal Swamp represents a testament to what may be achieved through collaboration among dedicated biologists and agencies.  The project had a lot of moving parts and success required that many things go right.  This would not have been possible without the dedication and enthusiasm of many people.  We thank staff from the Great Dismal Swamp, NWR, Carolina Sandhills, NWR, SDHamilton Noxubee, NWR, Okefenokee, NWR, two USFWS ecological services offices, Jay Carter and Associates, Inc., Virginia Department of Game & Inland Fisheries, The Nature Conservancy, The Center for Conservation Biology, and many volunteers.

IN MEMORIAM: Dr. Daniel W. Fort, former Rice Rivers Center Board Chair

January 5, 2016

The VCU Rice Rivers Center has lost a long-time stalwart, Dr. Daniel Fort. As a founding member and past Chairman of the Board of Trustees, Dr. Fort was instrumental in building the Center into the acclaimed research site it is today. From the earliest days of construction of the research pier, education building and the outdoor classroom, to supporting construction efforts on the upcoming overnight lodge, Dr. Fort was passionate about providing a world-class site on which to conduct education and research for the advancement of the environmental sciences. As a strong advocate of the Center’s work around the globe and a supporter of the collaborative approach to solve environmental problems, Daniel was eager to see the long-awaited research laboratory building come to fruition and persistently worked to make it a reality. His colleagues will miss his input as they press forward in his honor.

An accomplished medical doctor and avid outdoorsman, Dr. Fort was prolific in his charity and impassioned work in the fields of medicine and the environment. He made friends around the world through his devotion to his work, and his absence will be felt acutely. He is survived by his son Duncan Magee Fort; his sister Margaret Fort Bridgforth; his brother William Acrill Fort; four nieces and nephews; his longtime partner Kate Haw; and by countless friends young and old.

The VCU Rice Rivers Center expresses profound condolences to Dr. Fort’s friends and family. He will be sorely missed.

VCU Rice Rivers Center Launches New Website

December 2, 2015

After months of planning and preparation, VCU Rice Rivers Center is pleased to announce the launch of its redesigned website, planned to launch the first week of December. Executed by an outstanding team at VCU’s own University Relations, who gave the project much time and thought, the new website will offer an updated interface with interesting features, such as real-time data access, an interactive timeline, videos and a story tour map of the Rice Rivers Center detailing various research projects. As this is the final piece of a four-website project for VCU Life Sciences, VCU Life Sciences would like to thank the entire team at University Relations for their diligence, patience and humor over the course of the website development projects.

Rice Rivers Center Researchers Collaborate with Fort AP Hill

December 2, 2015

Researchers Cathy Viverette and Lesley Bulluck, Ph.D. recently have been awarded federal funding through the Cooperative Ecosystem Study Unit (CESU), for avian conservation work at Ft. A.P. Hill. The research will provide significant opportunities for graduate and undergraduate students in VCU’s Center for Environmental Studies and Department of Biology to engage in important research on Prothonotary Warblers and Red-headed Woodpeckers. Both species have suffered long-term population declines associated with habitat loss from degradation and conversion of forested wetlands and bottomland hardwood forests, and are considered species of conservation concern. In accordance with the Sikes Act, the Department of Defense (DoD) supports monitoring, inventory, research and management of migratory birds on DoD lands, and works with private and public partners to identify and protect key habitats and species.

The first project entitled “Reproductive Ecology and Migratory Connectivity of Prothonotary Warbler Populations at Fort AP Hill, VA” examines the ecology and management of Prothonotary Warblers (Protonotaria citrea), a neotropical migrant songbird of conservation concern. The main goal is to understand distribution and breeding ecology of the Prothonotary Warbler population at Fort A.P. Hill, VA. Density and reproductive success of Prothonotary Warbler populations can serve as indicators of ecological integrity of bottomland forest bird communities and the forested wetlands they inhabit. The study will build on a preliminary survey of Prothonotary Warbler populations at A.P. Hill conducted in 2015, and serve as a complement and comparison to a long term VCU study of box-nesting Prothonotary Warblers along the Lower James River, approximately 50 miles south of A.P. Hill. Researchers from VCU are also participating in a working group studying Prothonotary Warblers across their migratory range, so can engage partners and leverage resources in addition to those provided by the DoD, as well as apply results of this research to regional and international conservation efforts. To that end, Dr. Rodney Dyer will be contributing to the project by quantifying population structure of Prothonotary Warblers across their North American range.

The second project is entitled “Baseline Surveys, Breeding, and Wintering Ecology of Red-headed Woodpeckers at Fort A.P. Hill, VA”. The research team will examine the conservation and management of Red-headed Woodpeckers, a federal species of conservation concern experiencing long-term declines across North American breeding and wintering ranges. Fort A.P. Hill supports both breeding and wintering populations of Red-headed Woodpeckers (RHWO), providing a unique opportunity to address the identified knowledge gaps of this species of conservation concern. Although not well documented, it has been hypothesized that Red-headed Woodpecker declines are due to range-wide loss of primary habitat, particularly open oak woodlands and savannas. The main goal of this work is conducting baseline surveys of Red-headed Woodpecker populations at Fort A.P. Hill, VA during the breeding and non-breeding periods, as well as investigating factors associated with reproductive success and dispersal. Specifically we will be looking at fire and timber management implemented by the military to facilitate training to see how these impact Red-headed Woodpecker habitat use and movement.

Flood Zone Botany Walk

November 30, 2015

Science in the Park hosted a botany walk on October 31 in the James River flood zone. Twenty participants learned about hidden and not-so-hidden treasures of the James River Park System with VA Department of Conservation and Recreation Natural Heritage botanist John Townsend. John offered a wealth of knowledge about ecology in general, and the trees and shrubs of the fall zone in particular. He also touched on the lesser known groups of mosses and ferns along the way, but the elusive liverworts remained, well, elusive...

Science in the Park is sponsored by the VCU Rice Rivers Center and Friends of James River Park.

Researchers for a Day: Prince George High School

November 27, 2015

On October 29 and 30, Prince George High School students got a taste of hands-on science at the Rice Rivers Center. Guided by VCU M.S. and Ph.D. students, 25 juniors and seniors got to experience what it’s like to be a researcher in the field, asking questions, giving feedback and taking samples. Carbon sequestration in forests, gene flow in Black Widow spiders and Dogwood trees, and barrier island ecology were on display both in and out of the classroom. The high school students collected samples of Dogwood berries for Ph.D. candidate Jane Remfert, and learned about water quality monitoring from Mac Lee, who runs who runs VCU's Environmental Water Quality Lab. They also got a peek at the process of botanical illustration as they toured a field class taught by VCU Communication Arts professor Sarah Faris. In addition to being excellent exposure to scientific processes, the day was a great opportunity for these students on the cusp of their next phase of education to learn from older students what sort of routes they have traveled to arrive where they are now in their education.

Snakes and More!

November 26, 2015

The Virginia Herpetological Society held its Fall 2015 Meeting at the Rice Rivers Center on October 24. Over 50 people from around the state came to hear various research presentations on Cottonmouths (Agkistrodon piscivorus), Southeast Asian fanged toads, and more. A seven foot Eastern rat snake was in attendance.

New and Next for VCU Rice Rivers: Stay Over!

November 25, 2015

A long-anticipated development is underway at the VCU Rice Rivers Center: researchers, students and other collaborators soon will have the ability to stay onsite overnight in a beautifully-designed lodge that is planned to be operational by January 2017. Thanks to the continued generosity of Mrs. Inger Rice, four buildings will cluster around a courtyard which will include a fire pit for congregating. There will be a dining and meeting facility, as well as a variety of sleeping accommodations for differing types of groups. While the drive to and from the main university campus is not too long, the ability to stay for an extended period will afford not only our own students but also researchers from other organizations to gain closer access to their projects, and will be especially beneficial to avian researchers and others who need to operate in early, late, or non-daylight hours. In addition, the accommodations will allow greater use of the center for conferences and retreats. The VCU Rice Rivers Center is grateful to Mrs. Rice’s generosity and looks forward to sharing the center even more extensively.

Coming Soon: Research Labs, Library and Offices

November 25, 2015

Following closely on the heels of the overnight lodge at the VCU Rice Rivers Center, the critically needed Research Laboratory Building is in its final phase of fundraising. The hope is that once construction of the overnight facility is complete, work can begin on this last segment of the planned infrastructure necessary to attain the visionary goal set upon receipt of the property back in 2000 – that of being the go-to place for river science and water issues on the east coast. This research building will be set on the eastern edge of the bluff overlooking the wetland restoration site, across from the existing Education Building. Plans are being considered carefully to accommodate fully the growing needs of the environmental scientists at VCU, as well as those who collaborate with the university.

Please consider helping us to close the gap: We have raised approximately $4M towards the $6.7M needed to break ground for this exciting new resource for Virginia, the region and the study of rivers and water resource issues. Visit us at: https://www.support.vcu.edu/give/lifesciences to be part of this impactful project.

Dr. McGarvey Receives Career Grant From NSF

November 24, 2015

Dan McGarvey, Ph.D. has been awarded a National Science Foundation Career Grant for his project entitled, "CAREER: A Size-Based Test of Species-Energy Theory in Stream Ecosystems – Linking Individuals, Communities, and Underrepresented Minorities". Funding will be for five years and will create a rigorous undergraduate research program that will teach basic fieldwork skills in stream ecology to underrepresented STEM minorities, expose them to new environments, and gradually increase minority participation within the ecological/environmental sciences.

Studies of the predictable increase in biodiversity that occurs moving from the poles to the equator – known as the latitudinal diversity gradient – can reveal key drivers of biodiversity. Such knowledge is essential for basic science as well as applied efforts to conserve biodiversity in a rapidly changing world. One hypothesis that is often cited to explain the latitudinal diversity gradient is the species-energy hypothesis: biodiversity may be greatest in the tropics because the basal food resources that sustain organisms are most abundant there. This project will perform a direct test of the species-energy hypothesis using stream communities, sampled across a broad latitudinal gradient (10 to 44 degrees north latitude), as a model system. In each of eight study streams, fishes and invertebrates will be intensively sampled. Models of the relationship between average individual size and community-level abundance, which reflect the transfer of energetic resources between predators and their prey (large predators are less abundant than smaller prey), will then be used to test the species-energy hypothesis.

VCU Rice Rivers center extends hearty congratulations to Dr. McGarvey and his team.

Flowers, Fungus, Fine Art and Illustration

November 24, 2015

On October 30, VCU Communication Arts professor Sarah Faris took her Botanical Drawing class out to the VCU Rice Rivers Center.

They were given a project prompt focusing on “interaction”, and were allowed the choice of a fine art or scientific illustration approach. Using materials gathered on-site, students engaged in production of work that furthered their skills in observation, image making, expressiveness, and communication. Faris and her students posted images from the day under the Instagram hashtags #bioartschool and #vcuricecenter.

Students: Emily Rueckert (top), Lauren Rakes (L), and Erin Bushnell (R)In a fortuitous intersection, visiting Prince George High School students got a peek at the process of botanical illustration as they toured the lab where the Botanical Illustrations students were working, introducing them to another facet of scientific pursuit, in addition to the research they already had been helping to conduct at the Center that day.

Garden Clubs Visit Rice Rivers Center

November 23, 2015

In October, both the James River Garden Club and the Tuckahoe Garden Club held their meetings overlooking the James River at the VCU Rice Rivers Center. Following the meetings, members were treated to a presentation given by Anne Wright, Director, VCU Rice Rivers Center Outreach Education, as well as Janet Woody, Librarian at Lora M. Robins Library at Lewis Ginter Botanical Garden. Entitled “Fast Boats and Flowers — The Newton Ancarrow Story: Local environmental activism and the creation of an early flora for the James River Park System”, the talk brought to life the work of this unlikely hero of the James River. Members also enjoyed a comprehensive tour of the Rice Rivers Center, including the research pier and landmark wetland restoration project at Kimages Creek.

Electrofishing's stunning success in harvesting blue catfish raises concerns

October 20, 2015

VCU works with the Virginia Marine Resource Commission and Virginia Institute of Marine Science to find methods of trimming back populations of the over populated blue catfish through low-frequency electrofishing. While there are limitations, it serves as an efficient method to help control populations. Click here to read the full article from the Bay Journal. 

Shad, the 'founding fish,' is foundering

September 7, 2015

The American Shad once thrived in local rivers, including the James, serving as an important food source. Now, researchers say this fish could be in danger with populations at a low due in part to pollution, overfishing and habitat fragmentation. VCU's Dr. Greg Garman comments.

VCU Rice Rivers Center partners with Charlottesville restaurants in oyster restoration program

April 2, 2015

Thursday, April 2, 2015

An oyster shell recycling program through Virginia Commonwealth University’s Rice Rivers Center has expanded its operations to Charlottesville. With help from volunteers, the Virginia Oyster Shell Recycling Program (VOSRP) will soon start collecting discarded shells from local restaurants. The shells, which would otherwise be sent to a landfill, will now return to the Chesapeake Bay to create a natural habitat for new oysters.

“Once prevalent and seen in huge piles, oyster shells have become quite scarce in the Chesapeake Bay,” said VOSRP director Todd Janeski. “We ensure the shells are returned to the Virginia portion of the Chesapeake as part of restoration activities.”

The Charlottesville expansion builds off an already successful program in Richmond, where more than two dozen local restaurants recycled more than 50,000 pounds of shells in 2014. Oysters provide critical environmental services such as filtering up to 50 gallons of water a day by consuming sediments and pollution. The filtration process plays a significant role in the clarity of the water column, allowing for aquatic grasses to grow and providing a critical habitat for young fish and crabs. The oyster reefs offer a valuable hard bottom habitat for larger fish and shoreline protection from wave and storm impact. Additionally, the decomposing shells help to maintain steady pH levels in the bay.  

Oyster shell recycling provides local businesses with the opportunity to promote the protection and remediation of the Chesapeake Bay by becoming involved in the restoration of wild, native oysters. “I hate the idea of throwing away such a valuable commodity,” said Daniel Kaufman, owner of Public Fish and Oyster. “Sustainability is part of what we want to communicate to our customers and tossing oyster shells into a landfill doesn’t help our message.”

Other participating restaurants include Fosset’s at the Keswick Hotel, Blue Light Grill, Rhett’s River Grill and Raw Bar, and Rocksalt.

The program expansion is supported by the Virginia Sea Grant, and relies upon partnerships with  the Chesapeake Bay Foundation, Virginia Master Naturalist Program and the University of Virginia.

Three Chopt Garden Club visits Rice Rivers Center

November 12, 2014

On October 28, the Three Chopt Garden Club held their membership meeting at the Rice Rivers Center. It was a glorious day to experience the field station. Former James River Park System Manager/Naturalist, Ralph White, gave the keynote speech on the history and value of the James River. Catherine Dahl, Director of Development and Special Projects for Life Sciences gave a brief overview of the Center and how it fits in with the overall mission of river stewardship worldwide. Members enjoyed tours of the property, including the waterfront and the wetlands.

A forest out from under a lake

November 12, 2014

What WAS there? Once a vibrant wetland, then a well-stocked lake, and now in the process of restoration, Kimages Creek has experienced a great deal of change over the last 100 years. VCU graduate student Rick Ward is working to identify the flooded stumps in order that the wetland forest can be restored as well as possible to its former state.

Under the guidance of Dr. Ed Crawford, Ward has developed an 11-step process that begins in the wetlands, locating stumps by GPS and flagging them for mapping. A cross section of a stump (“cookie”) is carefully sawn from the stump, bagged and labeled. Once back in the lab, the cookies are dried in an oven and sanded on one face. After being given an approximate age by counting rings, the samples are placed under a microscope and compared to known samples, examining pores of early and late wood.

Using as reference a number of scientific publications, Ward works to discern the historical tree species found in the wetland area. He can determine which species were able to grow in both upland and wetland areas, and which species are “obligate wetland” and must grow there, like the Black Willow.

Starting with porosity and growth rings, there are 11 steps in Ward’s taxonomic identification code that can lead to identification of a genus of a tree. Because of the variety of conditions under which trees can grow, narrowing down to the species isn’t always possible.

So far, 46 extant species have been found, with the Sweet Gum tree being the most prevalent species along the edge of the wetlands. In terms of the historical forest, Ward and his team have only identified 15 species that comprise the over 5,000 stumps that have been located. The Nature Conservancy has been helping VCU Rice Rivers Center to restore the wetlands, having planted approximately 25,000 trees and shrubs thus far.

It was 1862 when Confederate and Union troops pulled out of the area, having clear cut the trees for fuel and sight lines for battle. Based on his research, Ward estimates that it took approximately 35 years for the forest at Kimages Creek to start flourishing once again. And now, with the help of The Nature Conservancy, Dr. Crawford, and Richard Ward, as well as other graduate and undergraduate students, the wetlands at Kimages Creek are well on their way to returning to their natural state for the first time in over 100 years.

Shell recycling update – don’t chuck that shuck!

November 12, 2014

The Rice Rivers Center’s Virginia Oyster Shell Recycling Program (VOSRP) has been very active recycling used shell, bringing more restaurants into the program, and generating a great deal of interest. We were invited to participate in Governor McAuliffe’s Virginia Oyster Trail Event at the Governor’s Mansion, kicking off an exciting initiative to encourage oyster-wine tourism in Virginia. Our “shuck buckets” were everywhere, and the Governor himself was notably enthusiastic about adding his used shells to the collection. At a follow-up event, he asked for the shuck buckets and was pleased to know we were participating.

Other events have included Shockoe on the Half Shell, Union Market’s “Eat Oysters! Drink Beer!” event, and Fire, Flour & Fork. Additionally, the Richmond Folk Festival featured a tent dedicated to the Virginia Oyster where World and Virginia champion oyster shuckers and sisters, Deborah Pratt and Clementine Macon-Boyd, kept sibling rivalry alive in an oyster shucking competition. The VOSRP collected shell there and interacted with participants of the Folk Festival, many of whom were VCU alumni.

The most recent partners added include The Savory Grain, Pomegranate, Westwood Club and Deltaville Oyster Co.

EcoExperiences at Rice Rivers Center: Hands-on learning for the public

May 30, 2014

On two days in May, VCU Rice Rivers Center hosted EcoExperiences as a way to open the center to the public and offer some first-hand science to all comers.

“Catch and Release Dragonflies” and “Bird Field Day” were opportunities to experience field work under the guidance of experienced teacher-researchers. Participants were treated to close-up looks at wildlife, and given an understanding of how research at the VCU Rice Rivers Center is conducted.

These were the first two events in a series of three for the year; the final EcoExperience for 2014 will be held Oct. 4, “Wading into Wetlands: An amphibian’s eye view of some exceptional ecosystems”:

Wetland habitats provide numerous ecosystem services such as clean water, clean air, critical habitat for threatened and endangered species, increased regional biodiversity, and are among some of the most productive ecosystems on the planet. Come learn about these critically important yet highly imperiled wetland ecosystems while you engage in hands-on exploration of some diverse and unique wetland resources located at the VCU Rice Rivers Center. Hip-waders will be provided as we investigate forested and herbaceous dominated tidal/non-tidal and ephemeral wetlands along the banks of the James River.

For more information, including how to register, please see the EcoExperience section of our Courses and Workshops page.

Publications up and rising at Rice Rivers Center

April 17, 2014

We are pleased to report that VCU Rice Rivers Center researchers have published thirty-eight papers thus far.

Smart river = James River

May 28, 2014

As part of the “Mountains to the Sea” partnership among VCU, the U.S. Geological Survey (USGS), Randolph-Macon College and Washington & Lee University, exciting developments are happening.

Each of the three schools involved is hiring a student intern, who will be working with researchers from VCU and the USGS this summer. They will be using new, cutting-edge water quality sensors, acoustic receivers and satellite telemetry equipment being installed at Weyanoke on the James River to monitor the hydrology, water quality and migratory fish movements within the river. The instruments will work in concert with existing equipment to provide real-time estimates of the amount of nutrients, specifically nitrogen, that move through the James River each year.

The hydrology and water quality data will significantly aid ongoing studies by Dr. Paul Bukaveckas on nutrient and algal dynamics in the river. Data generated by VCU’s acoustic receivers will support recovery efforts for the endangered Atlantic sturgeon and related research initiatives.

This project is generously funded by MeadWestvaco, Dominion, NOAA and the Jessie Ball duPont Fund.

International partnership with University of Cordoba

April 16, 2014

VCU Rice Rivers Center and the Department of Biology are pleased to announce the VCU-University of Córdoba (UCO) Collaboration: Development of a synthetic, complimentary degree program focusing on science of the James River and Guadalquivir River ecosystems.

The collaborative research project between VCU and UCO is designed to strengthen and expand the existing collaboration between faculty and students at both universities to enhance the sharing of resources, expertise and cultural experiences, and ultimately resulting in increased collaborative research and the development of a collaborative graduate degree.

The collaboration will focus on two river ecosystems, James and Guadalquivir, which are historically fundamental to the economy and culture of Virginia, USA and Andalusia, Spain, respectively. The central theme of the project is to evaluate the impacts of global change induced rises in sea level on these river ecosystems. Emphasis will be placed on ecological communities and broader impacts on societies within the river watersheds. Researchers will use historical and current understanding of sea level rise and associated effects on river and watershed ecological assemblages by using quantitative tools for watershed analysis, as well as computer simulations to predict future scenarios that will impact the rivers ecosystems and society. Hydro- and bio-indicators of this sea level rise impact will also be identified as tracers of the global change evolution.

VCU faculty will be travelling to Spain this June to kick off the collaboration.

Engaging work in Panama

April 15, 2014

VCU Rice Rivers Center’s annual trip to Panama this year was a success. Sixteen graduate and undergraduate students from VCU’s Center for Environmental Studies joined Dr. Lesley Bulluck and Dr. Ed Crawford on a two-week research excursion to the tropics.

Their goal while in Panama was to monitor migratory and resident birds in black mangrove forests of varying condition in and around Panama City. One week was spent doing intensive field work in the mangroves, where students learned how to band and measure birds captured in mist nets. Also, data was collected on the birds’ foraging behaviors and condition as well as vegetation and soil characteristics throughout the sites. The students currently are finalizing their data analysis and plan to present their major findings at the VCU Rice Rivers Center Research symposium, to be held Friday, May 9.

The second week abroad involved traveling to more remote locations in Panama to explore cloud forests. This year was different because we were able to host four university students from the University of Panama and the International Maritime University of Panama throughout the entire experience in Panama. This is especially exciting because it is rare for these students to gain experience doing field work or traveling to places beyond the city where they live. This course provides VCU students with an intensive research and service-learning experience that has proven to be life-changing.

LiDAR at Rice Rivers Center

April 14, 2014

On April 1, the Environmental Remote Sensing class met at the Rice Rivers Center to explore LiDAR (Light Detection and Ranging) data collection and processing. Students received a lecture and participated in discussion of the technology, and were able to spend time manipulating data using imaging software in order to gain a better understanding of this cutting-edge technology.

Using airborne and terrestrial data collection methods, remote sensing scientists are able to collect massive amounts of data to create dramatically accurate images. Students on this day were exposed to a dataset containing approximately 150 million data returns.

This technology is being developed and employed by scientists worldwide, and locally by the Engineer Research and Development Center (ERDC) of the U.S. Army Corps of Engineers (USACE). In this mutually beneficial partnership with Rice Rivers Center, the ERDC is using the center as one location to collect and test data.

LiDAR is used in environmental, humanitarian and military applications; for the Rice Rivers Center specifically, LiDAR is an excellent structural landscaping tool that is being used for the 70-acre wetland restoration project on the property.

Deciphering the winter composition of sharp-tailed sparrows

The sharp-tailed sparrow complex is a superspecies that includes two species (Nelson’s and saltmarsh sharp-tailed sparrows) and five subspecies.  The subspecies have distinct breeding ranges and include the “Acadian” sparrow that nests from Quebec to Massachusetts, the “James Bay” sparrow that nests along the southwestern margin of James Bay, the “Nelson’s” sparrow that nests in the northern Great Plains, the “north-Atlantic” saltmarsh sparrow that nests along the coast from Maine to New Jersey, and the “mid-Atlantic” saltmarsh sparrow that nests along the coast from New Jersey to Virginia.  Although these forms breed in far-flung locations, during the winter months they all converge and form mixed flocks along the mid- and south-Atlantic coast. 

We know surprisingly little about the composition and distribution of saltmarsh sparrow forms during the winter months.  The information gap is partly due to their winter ecology.  Sharp-tails utilize remote marsh habitats that are either not accessible or not preferred by the birding public, and they occur in low densities within vast marshes.  Even when encountered, they provide only fleeting glimpses as they pop up briefly in marsh grass.  Although the two species are readily discernable for experienced birders, the subspecies are not.  Clarifying the winter range of this species complex is of particular interest because all forms are saltmarsh obligates during the winter period, and as such are confined to a thin veneer of tidal habitat that is being subjected to increasing threats from sea-level rise.

Our perception about winter distribution of sharp-tails comes primarily from a careful compilation of museum specimens made by Greenlaw and Woolfenden in the early 2000s.  They identified the birds to subspecies and examined the distribution of collection sites.  The underlying assumption is that the distribution of where collectors worked reflects the distribution of subspecies.  However, from a sample of more than 660 birds only 25 specimens were available north of North Carolina and only 9 of these were from Virginia.  The suggestion that sharp-tails are relatively uncommon north of the Carolinas in winter does not comport with the experience of researchers working in the mid-Atlantic.

Between 2006 and 2014, CCB worked to investigate the winter bird community within 24 tidal marshes in coastal Virginia.  One objective for this work was to better understand the abundance and composition of the sharp-tail complex north of the Carolinas.  The work, led by Fletcher Smith, resulted in the capture and identification of more than 1,000 sharp-tailed sparrows.  CCB recently published a paper in the Wilson Journal of Ornithology entitled “Winter composition of Nelson’s sparrow and saltmarsh sparrow mixed flocks in coastal Virginia.”  This paper follows an earlier treatment of plumage differences between the five subspecies published by Fletcher in North American Birds (Subspecies of saltmarsh sparrow and Nelson’s sparrow).

 

Results of the fieldwork demonstrate that sharp-tailed sparrows are actually fairly common in Virginia saltmarshes and that all five subspecies co-occur and readily form mixed flocks during high tide events.  The north-Atlantic saltmarsh sparrow was the most common form, accounting for 45% of all birds identified.  The three Nelson’s sparrow forms were equally common and collectively accounted for 47% of the subspecies identified.  The highly restricted mid-Atlantic saltmarsh sparrow was the least common, accounting for only 8% of birds.  Contrary to current dogma, Nelson’s and saltmarsh sparrows are equally common in Virginia marshes.  Subtle differences in habitat use between these species may be just as important as geography in understanding their distribution during winter.

This work extends our understanding of the ecology and winter distribution of sharp-tailed sparrows and has implications for their conservation.  Due to their complete dependence on tidal marshes, these specialized sparrows sit on the front lines of impacts due to climate change.  The mid-Atlantic region is experiencing some of the highest rates of sea-level rise on the continent.  The marshes in the region appear to be much more significant to the future of the sparrows than previously understood.

Dana Bradshaw recognized for commitment to woodpecker recovery

August 19, 2015

Dana Bradshaw began work with the red-cockaded woodpecker in the fall of 1980 as a graduate student working under Mitchell Byrd in the biology department at the College of William and Mary. Having grown up in the heart of the species range in Virginia, Dana would bring a wealth of experience and a unique perspective to the work. The woodpecker had been classified as federally endangered and Virginia represented the northern edge of the species’ range. His thesis focused on foraging and home range requirements, topics that would later inform critical components of the state’s recovery strategy. But Dana’s enthusiasm for the woodpecker and commitment to its recovery would not end with his graduate work.

Dana would move on from graduate work to become the first biologist within the newly formed non-game program within the Virginia Department of Game & Inland Fisheries. Among other responsibilities, Dana would oversee red-cockaded woodpecker monitoring and management. He would later leave the agency to become a biologist and then a research associate within CCB. Despite working with many species and in many capacities, Dana continues to be one of the most consistent and knowledgeable voices for woodpecker recovery in Virginia.

Recently, in recognition of 35 years of commitment to the recovery of the red-cockaded woodpecker, CCB presented Dana with a framed photo. The photo, taken by John DiGiorgio within The Nature Conservancy’s Piney Grove Preserve, depicts a milestone event within the decades-long effort to recover the Virginia population. The bird, a female from North Carolina, was the first to breed in the state after having been brought in from another population. The translocation program was a successful management strategy that helped to reverse the population decline.

Whimbrel tracked into Tropical Storm Erika

August 28, 2015

VCU Rice Rivers Center and The College of William & Mary's Center for Conservation Biology

By Bryan Watts and Fletcher Smith

While most of us along the Atlantic Coast keep our eyes on Tropical Storm Erika churning in the Caribbean, Upinraaq (named for the Inuvialuktun word for summer) the whimbrel has already met with the storm in the middle of the open Atlantic. Upinraaq, wearing a tiny tracking device, was migrating south from Newfoundland to South America when she crossed paths with Erika nearly 1,000 miles east of the West Indies. Erika was a developing tropical storm with sustained winds of 46 miles per hour when the encounter occurred. Amazingly, Upinraaq had been flying non-stop for more than 3 days and 2,700 miles (4,300 kilometers) when she successfully flew directly through the heart of the storm and continued on to the coast of Suriname.

For generations, scientists have wondered how birds migrating from North America to South America during the height of the hurricane season. Do the birds fly around the storms? Do they die at sea? Do the birds have some way of predicting that storms are brewing and wait until the coast is clear? The rendezvous between Upinraaq and Erika represents the 9th such interaction between a migrating whimbrel and major storms that a tracking study has documented since 2007. Information from 31 flights over the Caribbean and Atlantic Ocean is beginning to reveal the migratory behavior of this large, migratory shorebird. Birds launching out over the Atlantic from the high latitudes of the Canadian Maritimes appear to have no inkling about storms forming in the lower sub-tropical latitudes. Despite flying out over the vast Atlantic with no place to hide, no birds have been lost at sea.

Although several birds have skirted around major storms while crossing the Atlantic, 6 birds have flown directly through the storms. One of the most incredible of these encounters occurred in August of 2011 when a bird named Chinquapin flew directly through the northeast quadrant of Hurricane Irene, a monstrous storm that caused extensive damage along the eastern seaboard. A second dramatic encounter occurred when a whimbrel named Hope flew through Tropical Storm Gert in the North Atlantic. This bird encountered high headwinds for 27 hours averaging only 9 miles per hour. Once through the storm, flight speed increased to more than 90 miles per hour as the bird was pushed by significant tail winds and made it back to Cape Cod, Massachusetts. In 2008, a bird was tracked into Hurricane Hanna and landed in the Bahamas only to be hit later by Hurricane Ike.

Although Upinraaq survived her encounter with Erika, she was not unaffected. She made landfall near Paramaribo, Suriname roughly 1,000 miles west of her winter range in Brazil. She will have to run a gauntlet of hunters along the coast of South America to reach her winter home. Scientists will be tracking her progress in the coming weeks. Upinraaq breeds along the MacKenzie River in western Canada. After the nesting season, she flies east to the Canadian Maritimes to stage for her long transoceanic flight to Brazil where she winters near São Luís and the Gulf of Maranhão. She leaves in the spring, flying to the Gulf of Mexico to stage before the long flight back to the breeding grounds.

Upinraaq is one of 36 whimbrels that have been fitted with state-of-the-art satellite transmitters and tracked throughout their annual cycle to discover migratory routes that connect breeding and winter areas and to identify en route migratory staging areas that are critical to the conservation of this declining species. The project is a collaborative effort between The Center for Conservation Biology at the College of William and Mary – Virginia Commonwealth University, the Canadian Wildlife Service, the U.S. Fish and Wildlife Service, Georgia Department of Natural Resources, The Nature Conservancy, and Manomet.

News of Hope

August 21, 2015

Hope the whimbrel was observed and photographed on 19 August, 2015 by Lisa Yntema on her winter territory at Great Pond, St. Croix. Hope has been recorded on this same small pond during the fall and winter months since she was captured and outfitted with a satellite transmitter in Virginia during the spring of 2009. She was last photographed there on 14 February, 2014 by Lisa before migrating to her breeding grounds along the Mackenzie River in the Northwest Territories of Canada.

Originally captured on 19 May, 2009 while staging on Boxtree Creek on the Eastern Shore of Virginia, Hope was tracked by satellite for over 50,000 miles (80,000 kilometers) between 2009 and 2012, including four back and forth migrations between breeding and winter grounds. She lost her transmitter antenna in the early fall of 2012 and was recaptured to remove the unit on 20 November of that year. She retains her coded leg flag for identification and Lisa has continued to observe her in the mangrove-lined pond since that time. She now would have flown an estimated 90,000 miles (145,000 kilometers) since the spring of 2009.

Hope’s incredible attachment to her tiny territory on Great Pond, her spring staging area on Boxtree Creek, and her breeding territory on the Mackenzie River has demonstrated to followers throughout the world the link between local actions and shorebird conservation. The subject of an award-winning children’s book, Hope’s story continues to inspire.

De Fur Named To Continue In Fisheries Management Council

August 19, 2015

Dr. Peter L. de Fur, Research Associate Professor in the Center for Environmental Studies and an Affiliate faculty member of the Rice Rivers Center, has been reappointed to the Mid-Atlantic Fisheries Management Council as the Virginia representative. The appointment lasts three years; in his role he will help address regulations for blueline tilefish, a new fishery under the Council's jurisdiction, how to recover the flounder population that is showing signs of compromise, and restoration of river herring.

The Mid-Atlantic Fishery Management Council is responsible for the conservation and management of fishery resources within the federal 200-mile limit of the Atlantic off the coasts of New York, New Jersey, Pennsylvania, Delaware, Maryland, Virginia and North Carolina.

The Mid-Atlantic Council is one of eight regional fishery management councils created when  Congress passed Public Law 94-265, the Magnuson Fishery Conservation And Management Act of 1976 (also known as Magnuson-Stevens Act, MFCMA or MSA). The law created a system of regional fisheries management that was designed to allow regional, participatory governance by knowledgeable people with a stake in fishery management.

The regional fishery management councils develop fishery management plans and recommend management measures for the Exclusive Economic Zone (EEZ) off the east coast of the United States (3-200 miles). State jurisdiction extends from the shoreline to three miles out, and all coastal states have their own laws and fishing agencies to manage fisheries within three miles of their coasts. The councils recommend fishery management measures to the Secretary of Commerce through the National Marine Fisheries Service (NMFS). The decisions made by the councils are not final until they are approved or partially approved by the Secretary of Commerce through NMFS.

The Council is made up of 21 voting members and four non-voting members. Seven of the voting members represent the constituent states' fish and wildlife agencies, and 13 are private citizens who are knowledgeable about recreational fishing, commercial fishing, or marine conservation. The four non-voting members represent the Atlantic States Marine Fisheries Commission, the U.S. Fish and Wildlife Service, the U.S. Department of State, and the U.S. Coast Guard.

The Mid-Atlantic Council develops fishery management plans and management measures (such as fishing seasons, quotas, and closed areas) for thirteen species of fish and shellfish. Several of these species are managed under multi-species fishery management plans because they are found in the same geographic region or have similar life histories.

For more information: http://www.mafmc.org/

Dr. deFur is one of two members with academic doctoral degrees; the other is a fisheries economist. Peter has experience conducting laboratory and field research on marine and estuarine species under the Council’s jurisdiction, and has worked on fisheries conservation and management for many years. In his first term, he chaired the committee that initiated the recent action to protect deep sea corals from fishery activities. Dr. deFur has been with VCU’s Center for Environmental Studies for more than 21 years, teaching graduate courses and advising graduate research projects.

Carbon Flux Tower Installed And Readying For Action

August 19, 2015

Dr. Chris Gough, Dr. Scott Neubauer and their team of researchers, including ILS Ph.D. student Ellen Stuart-Haentjens, are closing in on a long-anticipated installation of an eddy covariance flux system, located in the wetland restoration area of Kimages Creek at the Rice Rivers Center. By later this fall, instrumentation will be in place and data will be collected to contribute to studies that, among other applications, have implications for climate change.

A byproduct of fossil-based energy production is carbon dioxide, which is rapidly accumulating in the atmosphere and is implicated in contemporary climate change. Wetlands are among the most productive ecosystems on Earth and play a crucial role in offsetting carbon dioxide emissions by absorbing and storing carbon in plant biomass and soils. In the coastal zone, wetlands continually form new soil as they grow vertically to keep up with steadily rising sea levels; many coastal wetlands have been storing significant amounts of carbon for hundreds to thousands of years. Indeed, persistent and high rates of wetland carbon sequestration have motivated current “blue carbon” initiatives that are promoting the conservation and restoration of coastal wetlands. One important caveat is that wetland emissions of methane, a potent greenhouse gas, can offset some of their carbon sequestration functions. Quantifying and understanding what regulates carbon uptake and the simultaneous exchange of multiple greenhouse gases between wetlands and the atmosphere is essential to advancing science and developing effective management policies aimed at offsetting human-derived carbon emissions. The eddy covariance flux system employed here offers a powerful platform for quantifying carbon dioxide, methane, and water vapor fluxes exchanged with the atmosphere at the ecosystem scale, providing novel, real-time data for a restored wetland. Data products will contribute to course instruction, undergraduate and graduate research, and high-profile collaborative publications with VCU and international investigators. In the longer term, results from the study will inform land management and climate change policies that aim to offset human-derived greenhouse gas emissions through ecosystem management.

One thing that makes the Rice Rivers Center’s flux tower especially important is its unique location in a restored freshwater tidal wetland, an underrepresented ecosystem in the global network of towers measuring carbon sequestration and methane emissions. In other words, not much is known yet about this ecosystem’s ability to sequester — or perhaps emit — greenhouse gases. So, novel results from this location will be of high interest to ecologists and climate modelers.

An outcome of this installation will be VCU Rice Rivers Center’s partnership in an international network, FLUXNET, of meteorological tower sites that measure carbon sequestration and emissions in an array of ecosystems and climates, from wetlands to upland forests.  FLUXNET is a global “network of regional networks” that provides infrastructure to compile, archive and distribute data for the scientific community, land managers, and policy makers. It works to ensure that different flux networks are calibrated to facilitate comparison between sites, and it provides a forum for the distribution of knowledge and data between scientists.

As of April 2014, there are over 683 tower sites in continuous long-term operation. Researchers, including those at Rice Rivers Center, collect complementary data on site vegetation, soil, trace gas fluxes, hydrology, and meteorological characteristics at the tower sites. The VCU Rice Rivers Center looks forward to joining this international collaboration in the coming year, and partnering with other field stations globally to understand how the Earth’s ecosystems affect global climate.

Oyster Shell Recycling Effort In Demand, Needs Volunteers

August 19, 2015

Since its inception in May of 2013, the Virginia Oyster Shell Recycling Program (VOSRP) has grown to encompass more parts of the state, with recycling efforts in Richmond, Charlottesville, Hampton Roads, and the Northern Neck. Interest is high from all corners of the region. The VOSRP continues to be directed by Todd Janeski, who administers all aspects of the Program including recruitment of private and public partners, volunteers, shell distribution, transportation and ensures the shell are appropriately utilized.

The Program struggles to operate on a limited budget of small direct donations and grants, but despite this hurdle, the grass-roots effort has provided much-needed material for oyster reef restoration in Virginia. Shell collection efforts have been so successful that more restoration areas are being evaluated for shell donations.

The Northern Neck of VA now has a public oyster shell drop-off location in Kilmarnock as part of the shell recycling program. Located at the Lancaster County Refuse Collection and Recycling site, this shell drop-off location would not have been possible without the help of the Town of Kilmarnock, VA, Lancaster County, Lamberth Building Materials, Chesapeake Bay Foundation - Hampton Roads Office, Byrd's Seafood Co, LLC, Windmill Point Oyster Co., The Dog and Oyster Vineyard, Hope and Glory Inn, Kilmarnock Farm and Garden, Virginia Oyster Country, and the Rappahannock Record. The shells collected will be returned to the VA portion of the Bay as part of oyster restoration activities.

In Richmond, Metzger Bar & Butchery and Ruby Salts Oyster Company hosted $1 Oyster Night to benefit the shell recycling program. With the help of Chris Buck of Ruby Salts, hundreds of oysters were sold to a standing room only crowd where Janeski and Buck educated the public on the benefits of returning their shells to the Bay.

Also in Richmond, the VOSRP has caught the attention of the Governor and his wife, who are staunch supporters of the recycling efforts; the Governor's Mansion participates in the recycling program by collecting their used shells.

And finally, the VOSRP has gotten its fair share of press in recent months, including this article in the July issue of Richmond Magazine.

With a number of events scheduled for the fall, the VOSRP is always willing to accept new volunteers to help with collecting shells from the program partners, seek funding and assist with events. The VOSRP is continually seeking funding to support the implementation of the program to meet the demand from the additional communities.

Local teacher who partners with VCU earns Presidential Innovation Award for Environmental Educators

July 30, 2015

President Barack Obama this month named Goochland County middle school teacher Anne Moore a recipient of the Presidential Innovation Award for Environmental Educators. The PIAEE awards are given to 15 environmental educators nationwide who use innovative, hands-on and experiential approaches in their lessons. Moore’s award was based in part on her involvement in a research consortium with Virginia Commonwealth University, informally named the Team Warbler project.

Through collaboration with VCU faculty and students, Moore leads her Goochland Middle School students in the study of prothonotary warblers, a migratory bird that breeds along rivers that feed into the Chesapeake Bay and spends winters in the tropics. Team Warbler includes community partners such as the Audubon Society along with the VCU Center for Environmental Studies and the VCU Rice Rivers Center.

Each winter VCU students enrolled in the Panama Avian Ecology course travel to Panama for two weeks to study the warblers wintering in tropical mangrove forests fringing the Panama Bay. While there, they work closely with the Panama Audubon Society and host local Panamanian schoolchildren for a day in the field to observe the research. When the VCU students and faculty return to Virginia, they teach Moore’s students about wetlands, warblers and conservation challenges shared by communities living on both the Chesapeake and Panama Bays.

Moore’s students have participated in hands-on learning activities, from measuring the light reflected in a bird’s feather to collecting data on nest predation rates along a rural-urban gradient. They also design and build nest boxes to be used at VCU’s long-term study sites along the James River. The work culminates at the end of the spring semester with the middle school class joining the VCU team for a day of hands-on learning about warblers and wetlands on the James River.

The project, now in its fifth year, is based on the concept that preservation of habitats critical to migratory birds is often important to the environmental, economic and cultural well-being of nearby communities, and long-term conservation of these habitats requires cross-cultural cooperation and understanding.

“To solve our future environmental challenges, young people need to understand the science behind the natural world and create a personal connection to the outdoors,” said Environmental Protection Agency administrator Gina McCarthy. “These teachers and students are demonstrating the important role of environmental education, and showing how individual actions can help address climate change, protect the air we breathe and safeguard the water we drink.”

Living in a world full of hazards

July 8, 2015

VCU Rice Rivers Center collaborator: Center for Conservation Biology

By Bryan Watts

Black over red 3-8 was a male peregrine falcon that was hatched on a railroad bridge that crosses the Elizabeth River in Norfolk, VA, in 1993. Within 3 years the bird established a new breeding territory on the Benjamin Harrison Bridge near Hopewell, VA, and produced 27 young over the next 10 years. On 12 February 2007 the bird was found dead near the bridge. Like so many other peregrines that we have tracked over time, the old male flew into a guy wire and was killed.

We kill billions of birds across the globe every year. Many of these birds are like 3-8, unintentional casualties of the infrastructure we have built to support modern society. They fly into hazards that we have erected in their airspace like tall buildings, transmission lines, radio towers, and wind turbines. They are poisoned by chemicals or soiled by oil spills. They become entangled in fishing gear or are hit by cars or trains or airplanes. Some are killed intentionally by hunters or by people who classify them as pests.

Like with human mortality, we have spent considerable time and effort to quantify the major causes of death. In the United States alone, we estimate that every year nearly 60 million birds are killed by vehicles, 50 million are killed by communication towers, 70 million are killed by pesticides and possibly as many as 1 billion are killed when they fly into buildings. A recent study has estimated that free-ranging domestic cats in the United States kill more than 1 billion birds annually. Understanding mortality factors is an important step toward improving survival. However, mortality factors represent only one side of the story.

From a conservation perspective, the central question is not how many individuals are killed annually but whether populations have the capacity to absorb the mortality incurred and still reach management objectives. Understanding the relationship between realized mortality rates and sustainable mortality limits serves to focus management actions on factors that have the potential to cause population declines. Over the past several years, The Center for Conservation Biology has been borrowing from harvest theory to estimate sustainable mortality limits for species of conservation concern.

In 2010, CCB evaluated sustainable mortality limits for waterbird populations using the Western North Atlantic to provide a foundation for understanding potential impacts of offshore wind development (read Wind and Waterbirds). More recently, we have worked with the Canadian Wildlife Service and the U.S. Fish and Wildlife Service to estimate sustainable mortality limits for populations of migratory shorebirds using the Atlantic Flyway to better understand the potential impact of shorebird hunting. A paper from this work will be published during the summer of 2015 and is now available online. Following this effort, we have recently worked to estimate sustainable mortality limits for shorebirds using the East Asian-Australasian Flyway to better understand how hunting and other factors may be causing population declines.

Virginia Red-cockaded Woodpeckers finish season by fledging 21 young birds

July 7, 2015

VCU Rice Rivers Center collaborator: Center for Conservation Biology

By Mike Wilson

The breeding season for red-cockaded woodpeckers at the Nature Conservancy’s Piney Grove Preserve drew to a close with fledge checks completed during June and July. Thirteen breeding groups produced only 21 young, including 10 males and 11 females. The term “breeding group” is used because red-cockaded woodpeckers are cooperative breeders where a breeding pair is often assisted in incubation or nest provisioning by helper birds. The 2015 reproductive rate was low compared to the past several years when young per pair has averaged 1.5. Five of the 13 breeding groups that laid eggs failed to fledge any young and one group never laid eggs this season. The lower reproductive output this season was due in part to new breeding pairs that have settled in lower quality habitat and/or are inexperienced. Inexperienced pairs seem to raise fewer young in their first few years. Even some of the long-standing breeding groups that have had a recent turnover of breeding individuals fledged fewer birds than usual. The groups that have retained the same breeding individuals for at least the last 3 years produced larger (3-4 young) broods.

The low reproductive output this season does not undermine the overall success of red-cockaded woodpecker population growth and habitat management at the Preserve. The number of potential breeding groups has almost doubled since 2010. Three new breeding pairs were established in the 2014 breeding season including a site pioneered without the facilitation of artificial recruitment cavities, a first in Virginia since the 1980s. Long term restoration of the habitat at Piney Grove by the Nature Conservancy along with partners such as the U.S. Fish and Wildlife Service, Virginia Department of Game and Inland Fisheries, and the Virginia Department of Conservation and Recreation, has now provided red-cockaded woodpeckers with substantially more breeding and foraging opportunities than have ever existed at this site. This management has benefitted the entire suite of species that rely on the open-canopy southeastern pine ecosystem. The preserve harbors the greatest density of northern bobwhites, red-headed woodpeckers, brown-headed nuthatches, prairie warblers, and field sparrows in Virginia. The Piney Grove Preserve serves as a model for southeastern pine management within the region and, along with adjacent sites such as the Big Woods Wildlife Management Area and State Forest, forms the cornerstone for long-term ecosystem restoration.

The Center for Conservation Biology will continue annual monitoring of this population with the next activity being the winter census, during which all red-cockaded woodpeckers in the population will be counted to determine status and movement of individuals between groups.

CCB launches new and improved Mapping Portal

July 6, 2015

VCU Rice Rivers Center collaborator: Center for Conservation Biology

By Marie Pitts and Bryan Watts

Information is the one lasting contribution that science makes to society. Information is also the common thread that joins all of the diverse disciplines of conservation biology together. The primary focus of The Center for Conservation Biology is the collection, interpretation, and dissemination of information that is central to solving today’s environmental problems. We believe that information is vital to effective conservation and we are committed to meeting the information needs of an expanding community of end users.

In 2009, The Center launched the Virginia Bald Eagle Nest Locator, an online platform that allows users to interact with up-to-date eagle survey results. Due to regulatory requirements, this data resource is in high demand and making the information available online has improved and streamlined the permitting process. This application receives more than 20,000 visits per year. To learn more about the bald eagle annual survey, or to interact with survey data, visit the Eagle Nest Locator data in the Mapping Portal.

Responding to the conservation community, The Center has added new features to the Eagle Nest Locator. Beginning in early 2015, The Center requested assistance from AidData (a group with tremendous technical capacity that provides geo-referenced data focused on global aid) to update the features and offerings of the Mapping Portal. Some notable upgrades include: a substantial distance and area measuring tool, a “Generate Link” button that saves the current map view in the URL bar so that you can bookmark or share it with others, a “Print Report” button that generates a one-page report pdf file, and a set of Draw Tools that allow you to add your own lines, shapes, and markers. You can learn more about the new Mapping Portal features on theMapping Portal FAQ page.

In addition to several new applications, CCB is providing an expanded list of data resources to the Mapping Portal including the National Eagle Roost Registry and recent Colonial Waterbird Surveys. Communal roosts used by bald and golden eagles are locations where numerous eagles spend the night. Roosts are federally protected from disturbance, and the Mapping Portal provides information for regulators by showing roost centroids, polygons, primary/secondary buffers, and a topographic map. Waterbird species are also represented in the Mapping Portal, with layers for the 2003, 2008, and 2013 Colonial Waterbird Surveys. All of these surveys have systematically covered all 24 species of colonial waterbirds throughout the Coastal Plain province of Virginia, and allow for the development of conservation strategies for these sensitive populations. Layers for ongoing citizen science projects OspreyWatch and the U.S. Nightjar Survey have also been added. Stay tuned for newly added data layers!

Red Skies at Morning, Black Rail Warning

July 2, 2015

VCU Rice Rivers Center collaborator: Center for Conservation Biology

By Mike Wilson

Like the old sailor’s adage, surveys conducted by The Center for Conservation Biology are providing an ominous forecast on the status of black rails within the mid-Atlantic region. Black rails are declining rapidly and are on a crash course for extirpation from the mid-Atlantic region in our lifetime. Biologists at CCB have been conducting a multi-year effort to document the distribution of the black rail throughout this region and recently completed the 2nd year of a 2-year study to determine the status of black rail in North Carolina. It is our hope that locating populations of this species will allow for their protection and management and will help to ensure their future.

Results of the black rail survey in North Carolina tell a tale much like those of Virginia, Maryland, Delaware, and New Jersey. In the mid-Atlantic, black rails currently occur in a small number of places relative to the amount of available marsh habitat and have declined substantially within their greatest strongholds. We detected black rails at only 19 of 262 survey points in North Carolina, with 9 of these positive locations in close proximity to one another on the Cedar Island National Wildlife Refuge. The Cedar Island National Wildlife Refuge has long been known to harbor a significant population of black rails with historical accounts of more than 30 birds. However, surveys on the refuge over the last two years have only detected 8 birds. The remaining 10 detections were widely scattered across marshes in coastal counties, with locations including areas such as the Hobucken marshes, where rails have been known to occur since the 1990s. Detections at these off-refuge locations were typically of single birds.

The reasons for the decline of black rails are not completely understood. It is thought that declines may be a result of sea-level rise, nest predators, mosquito control (i.e., ditching and insecticides) and other incompatible management such as prescribed burning, or a combination of these factors. The mid-Atlantic region is projected to undergo a 2-meter rise in sea level in the next 100 years. Rising sea-level can negatively influence habitat over the long term by transforming the high marsh that rails rely on for breeding sites into low marsh, or in the short term by disrupting reproduction due to higher than normal flooding that damages nests and drowns eggs. Overall, the dramatic population loss of Black Rails across eastern tidal salt marshes provides indication that the ecosystem they rely on is no longer suitable. Emergency management actions are required to prevent further population loss and begin restoration.

Project funding for the North Carolina black rails survey is made available through partnership with the North Carolina Wildlife Resources Commission and the U.S. Fish and Wildlife Service.

 

CCB completes successful season of Red Knot resighting in Georgia

July 1, 2015

VCU Rice Rivers Center collaborator: Center for Conservation Biology

By Fletcher Smith and Bryan Watts

Conditions within spring staging sites along the western Atlantic Coast are critical to the future of the rufa population of red knots, which was recently listed as “threatened” under the U.S. Endangered Species Act. While staging within these sites, birds must build a large enough energy reserve to complete their flight to the Arctic and arrive with enough of a surplus to initiate reproduction and take advantage of the short breeding season. Although considerable work has been conducted to identify and study staging sites within the mid-Atlantic region, much less is known about the distribution and status of sites along the south Atlantic Coast. Filling information gaps about the importance of this region in the life cycle of this imperiled population has become a conservation priority.

The Center for Conservation Biology recently completed the 2nd year of a 3-year study of red knot distribution and population size in coastal Georgia during spring migration. The focus of fieldwork was to use previously flagged birds to examine duration of residency, local movements, connectivity with other staging areas and the number of birds using the coast of Georgia. The project focused on several locations and involved repeated visits to these sites to read leg flags. Information will be used to better understand the importance of the south Atlantic Coast and to designate critical habitat for this population.

One of the interesting observations during the 2015 season was the foraging flexibility demonstrated by the knots staging in Georgia. Throughout April, knots fed on small clams. As horseshoe crab spawning events were initiated in late April and early May, knots fed on concentrations of crab eggs during high tide and would then switch to feeding on clams when the outgoing tide exposed them to the birds. This two-fisted strategy is highly efficient and different than those of knots in Delaware Bay that feed mostly on horseshoe crabs and knots in Virginia that feed mostly on clams and mussels. In Georgia, the knots fed exclusively on clams in April, fed on clams and crab eggs in late April through mid-May and then fed exclusively on crab eggs in late May. Large concentrations of other shorebirds (including semi-palmated sandpipers, short-billed dowitchers, sanderlings, and ruddy turnstones) were observed feeding on horseshoe crab eggs as well.

 

Several large flocks of red knots were monitored along the coast between Tybee Island and Brunswick. The peak count was on the 23rd of May, when approximately 6,000 knots were seen at the primary roosting and foraging sites. Over 5,000 knots departed Georgia between 24 and 26 May. This late departure suggests that the birds are flying directly from the Georgia Coast to arctic breeding grounds.

This project is a collaborative effort by US Fish and Wildlife Service, Georgia Department of Natural Resources, Manomet Center for Conservation Sciences, The Nature Conservancy, and The Center for Conservation Biology. Significant assistance was provided by the staff of Little St. Simons Island and by Pat and Doris Leary and Perri Rothemich. Funding for the three-year project is provided by US Fish and Wildlife Service, National Fish and Wildlife Foundation, Georgia Power, and The Center for Conservation Biology.

Rediscovering Dolly

June 24, 2015

By Bryan Watts, Center for Conservation Biology

We mark wildlife in order to identify individuals during future encounters. For some individuals this allows us to determine where they go, how long they live, where they breed and how many young they produce over a lifetime. Releasing a banded bird into the wild is often coupled with a sense of possibility and wonder. We wonder if we will ever hear about this bird again. Will someone, somewhere identify the bird and provide a report of the encounter? In a similar way, when we encounter a marked bird we wonder when and where it was marked and by whom. For some, the story that emerges is unexpectedly rich.

On 26 April 2005, an eaglet was hatched in the Birmingham Zoo by two non-releasable adults given the names Camilla and Gonzo. Camilla was brought to the zoo in 1985 after being shot in Florida. Gonzo was also brought to the zoo in 1985 after he suffered an injury from fishing gear near Seattle, Washington. The eaglet produced by the pair was raised by the zoo until it was 6 weeks old, then driven by Cindy Pinger (Curator of Birds) on 8 June 2005 to the American Eagle Foundation’s (AEF) Douglas Lake hacking facility near Dandridge, Tennessee. The bird was banded with an aluminum band that bore the unique code 629-43814. Following a national naming contest held by AEF, the eaglet was named Dolly in honor of country music legend and AEF patron Dolly Parton.

“Dolly” the eagle was housed in the hack tower overlooking Douglas Lake until release on 26 July when she was 13 weeks old. Two days before release, Dolly was fitted with a patagial marker on her left wing that read “5C” in orange digits on a white oval over a green background. On this same day, Dolly was fitted with a tail-mounted radio transmitter and weighed. She weighed 9.8 pounds. After dispersal from the hack site, Dolly was not observed again until 7 months later, when she was photographed by David Bean on 29 March 2006 and identified by her patagial marker on Swift Creek Reservoir just 12 miles southwest of Richmond, Virginia. Following this unusual encounter, Dolly was not noticed again for more than 3 years.

Captain Mike Ostrander from Richmond runs fishing, wildlife viewing, and history boat tours along a stretch of the James River referred to as Jefferson’s Reach. In the fall of 2009, Ostrander observed an eagle pair establishing a territory along the shoreline of Hatcher’s Island. He would later recognize that the female adult was banded and nicknamed her “Bandit.” Dolly had likely lost the patagial marker and transmitter years before. It would take a number of skilled photographers and many photographs to eventually piece together the aluminum band code 629-43814 to identify Dolly and unlock her long story.

 

Since the fall of 2009, Ostrander has chronicled the details of Dolly’s life along Jefferson’s Reach. He has watched her lose several nests to storms only to rebuild before each breeding season. He has documented at least 3 different mates. For 4 years he has observed Dolly fight to keep her territory against repeated intrusions by competing females, including one bird that persisted along the boundary of the territory for more than a year. He has observed her vacate the territory when injured only to reappear and exert her control unexpectedly. Although Dolly has attempted to breed through the years, she produced no young until 2015.

Dolly, now in her 11th calendar year and 6th breeding season, produced a single young in 2015. During CCB’s first aerial survey of the James on 7 March, we observed Dolly incubating. Later in the spring on 29 April, we observed a single young in the nest that was approximately 2 weeks old. This young was observed in the nest throughout the late spring and successfully fledged in June.

From an unlikely beginning in an urban zoo, Dolly has struggled to establish herself and produce young along the James River during a time in the population’s recovery when competitors are many. People along the way who care about bald eagles have contributed to her story, and others have discovered her history through their own curiosity. She has become a fixture along the shoreline of Hatcher Island.

To see Dolly in person and the many eagles of Jefferson’s Reach, take a trip with Captain Mike Ostrander along the James River.

Eagles continue their advance along James River

June 16, 2015

VCU Rice Rivers Center collaborator: Center for Conservation Biology

By Bryan Watts

The James River continues to be one of the best barometers of bald eagle recovery within the Chesapeake Bay and likely the nation. Not only does the breeding population continue to rise to new highs year after year, but the birds are revealing patterns that reflect their shifting ecology.

The 2015 aerial survey of the James conducted by The Center for Conservation Biology recorded 236 pairs that produced 313 young. The population increase (6%) over the 2014 season is slightly lower than the 30-year average and begs the question of when the growth of this population will begin to level off. Productivity (1.3 chicks/pair) is comparable to that recorded on the river over the past ten years, with 20% of pairs failing to produce any young and 10% of pairs producing three-chick broods.

The sheer size of the population, its momentum, and the short period of recovery from the DDT era are astounding. In 1990 the James supported only 18 breeding pairs of eagles, and as recently as 2000, the river supported only 57 pairs. Charles City County alone now supports 51 pairs. The concentration of pairs within this historic county is part of a larger pattern of distribution along the river. Much of the colonization over the past 20 years has occurred within the upper, low-salinity reach of the watershed. In the early 2000s, breeding density was 4-fold higher along the freshwater reaches compared to the saltier reaches near the mouth of the river. Over the past 15 years, the density gap has continued to widen with the fresher areas now supporting densities more than 10 times higher than those of areas closer to the mouth of the river. This distribution pattern points to the areas along the river that are best suited to support breeding eagles. These same areas are where we should focus eagle management activities.

 

Since the aerial survey along the James River was initiated in 1962, we have seen the population decline to zero only to roar back in recent years to modern highs. Now that the population appears to be “out of the woods,” why do we continue to invest in surveys of this recovering population? The answer is that this ecological story is not complete. Many questions remain that are significant not just to eagles but to understanding many other predator populations across the planet.

Trailblazers club visits Rice Rivers Center

June 10, 2015

The Trailblazers of Ford’s Colony visited the VCU Rice Rivers Center on May 14; about 30 people came to hike the trails, kayak through the wetlands and bike the surrounding beautiful area. This group focuses on planning visits to sites of “interest” and chose the RRC as one which was of definite interest to this engaged and active group of outdoor adventurers. Having been given a brief presentation on the research, education and outreach done at and through the Center, a participant noted, “It is so good that you are doing this important work.”

 

Saving a songbird

June 16, 2015

The golden-winged warbler (GWWA) is a declining migratory songbird that requires high elevation shrubland habitat. In Virginia, the highest concentration of this species is in the mountains that mark the headwaters of the James and Potomac Rivers (specifically, in Highland and Bath Counties). Virginia Department of Game and Inland Fisheries (VDGIF), Virginia Commonwealth University (VCU) and The Nature Conservancy are all members of the Virginia GWWA Partners, a working group of the Virginia Bird Conservation Initiative. VDGIF contracted with Dr. Lesley Bulluck (Assistant Professor of Biology and an Affiliate Faculty Member of the VCU Rice Rivers Center) to purchase and deploy 25 geolocators in the Allegheny Highlands this spring. This effort is part of a larger, range-wide effort to understand the degree of migratory connectedness among breeding populations in North America and non-breeding areas in central and South America resulting in further connectivity between researchers from far flung parts of the globe — a collaboration perfectly exemplified by the assistance given by three crew members from the University of Minnesota who visited the Rice Rivers Center to show the team how to deploy the units.

 

“Footprints on the James” class

June 10, 2015

Beginning on May 18, the much-anticipated return of this fascinating class began. Starting with preparations in town at the VCU Outing Rental Center, the class geared up for a four week journey that will cover the length of the James River. From the headwaters near Irongate all the way to Jamestown, the class is traveling in canoes and kayaks and camping along the way, including a stop at the VCU Rice Rivers Center. The aim of the class is to explore the past and present of the river from a historical and biological standpoint, paying particular attention to the influences these areas have on each other. The class is a collaboration between the Department of Biology and the Center for Environmental Studies.

Rice Rivers Center director featured speaker at Focus Club

June 10, 2015

On April 27, Dr. Len Smock, Director of the VCU Rice Rivers Center, was the speaker for the Richmond Focus Club’s final meeting of the 2014-2015 season; he gave a comprehensive overview of the Center and the research conducted therein. The Focus Club, in existence since 1953, is aimed at increasing awareness and involvement in civic matters. The Rice Rivers Center is grateful for the opportunity to spread understanding of the issues that face not only the James River, but rivers worldwide, their watersheds and the species that inhabit those watersheds.

Students connecting the bays

June 10, 2015

On May 12, VCU Graphic Design professor and VCU Rice Rivers Center’s artist in residence, Laura Chessin, began a quest to tell the story of connections. Accompanied by Wyatt Carpenter, graduate student in the Center for Environmental Studies, Chessin has launched a blog to help track their journey from Virginia to Panama.

As part of a Community Engagement grant co-authored with Cathy Viverette, Lesley Bulluck and Ed Crawford, this trip is an effort to continue to make connections between the people and resources of Panama and Virginia. Chessin notes, “As we connect cultures, we emphasize that we share resources and conservation challenges. Protection of habitat for the Prothonotary Warbler—the bird that is at the center of all of these Panama-Virginia projects— and the many species of plants and animals living throughout their ecosystems is important to nearby communities. Things important to avian communities are important to human communities — essential things for quality of life: clean water, healthy habitat, good food sources, and sustainable livelihoods.”

Since 2010, TEAM Warbler has been working with students from Chesterfield and Goochland Middle Schools learning about the Prothonotary Warblers and the critical wetland habitats that sustain them here in Virginia. During the summer of 2014, Chessin featured students from Goochland Middle School exploring the Chesapeake Bay along with VCU researchers in her film “From BaytoBay”. This year she returned to Panama to tell the story of middle and high school students exploring the critical mangrove habitats fringing Panama and Chame Bays. They began the journey by starting with middle school students at Sabot Stony Point, gathering notes, drawings and stories from the students and a teacher by way of introducing themselves to the students with whom they would connect in Panama.

This summer, Chessin will take the footage collected on their journey and use it to further tell the story of the Warbler project, the mangrove preservation and restoration efforts, sustainability and the human connections being made across the sea.

Linda Fernandez, Ph.D. lead investigator on Arctic bioeconomic analysis

June 10, 2015

It has been called the “wild west” and one of our last frontiers; VCU’s Linda Fernandez, Ph.D. aims to help save it. Funded under the Belmont Forum, an international consortium focusing on global environmental research and the NSF, Fernandez’ international team has received a grant of over $700K to cover five years of study.

The project is entitled “Bioeconomic analysis for Arctic Marine Resource Governance and Policy” (abbreviated BAAMRGP).

The aim of the study is to provide insights for governance and marine resource management in order to prevent, contain, mitigate, and/or adapt to changes in Arctic marine resource productivity. The questions that must be answered include:

  1. What are the bioeconomic features of Arctic marine resources at risk of change over space and time?
  2. How do human behavior and policy incentives directly and indirectly impact these marine resources?
  3. What are the best governance options for Arctic marine resources?

Fernandez and her team will develop, through innovative bioeconomic analyses and application of game theoretic tools, integrated marine resource management tools for decision making designed for the unique Arctic environment, its complex geopolitical configuration, and the changing risks and uncertainties over space and time.

An international interdisciplinary and transdisciplinary research team of principal investigators has been established. They will focus on the dynamics of existing and new commercial fisheries generated from introduced invasive species, the threat of marine invasive species, vessel strikes of marine mammals and noise from vectors accompanying increasing trade and marine infrastructure in the Northwest Passage and Northern Sea Route. Their research offers predictive analysis of policy and governance options to sustain marine resources through an integrated framework that formally includes adaptive management through use of Arctic Observing Systems data. The researchers address three themes:

  1. The Natural and Living Environment,
  2. Natural Resource Management and Development and
  3. Governance.

This research will result in an integrated ecological and game theoretic behavioral framework that contributes to Arctic stewardship by enabling policymakers to specify appropriate policies for sustainable harvest practices, abating invasive species and marine pollution, and optimal resource conservation. Through the policies, society and the economy linked to the Arctic are positively impacted. The research plan calls for engagement with two Arctic Council working groups: the Conservation of Arctic Flora and Fauna and the Sustainable Development Working Group.

Fernandez’ team includes Brooks Kaiser, University of Southern Denmark, Esbjerg, Denmark; Jan Sundet, Institute of Marine Research, Tromsø, Norway; Niels Vestergaard, University of Southern Denmark, Esbjerg, Denmark; Whitman Miller of the Smithsonian Environmental Research Center, Annapolis, MD; Sergey Bakanov and Konstantin Sokolov, Polar Research Institute of Marine Fisheries and Oceanography, Murmansk, Russia; Sue Moore, NOAA, Seattle, WA.

Rice River Center’s own Anne Wright receives award

June 10, 2015

Friends of James River Park has honored three individuals to be the 2015 Ralph White River Hero Award winners in a ceremony held on April 30 at the VCU Rice Rivers Center. In 2011, the Friends of the James River Park launched the River Heroes Award as a way to acknowledge and honor individuals and organizations that have made significant contributions to the James River Park System. The award was renamed the Ralph White River Hero Award in 2015 to honor the contributions of former Park Superintendent Ralph White.

Honorees are chosen for a variety of reasons, which include volunteer work, educational efforts, preservation, and promotional activities that encourage responsible use of the Park. VCU Rice Rivers Center’s own Anne Wright was one of three recipients, honored for her cumulative work in the James River Park system over many years with special emphasis on the excellent work she has accomplished in developing and launching the Science in the Park website. Though many talented and knowledgeable individuals have contributed to this wonderful program, Wright has been central to the collaboration and this award acknowledges her critical role.

The VCU Rice Rivers Center extends hearty congratulations to all three of the winners.

iNaturalists contribute citizen science data in park system

June 10, 2015

On May 16, the public was invited to “Become an iNaturalist Photographer” in the James River Park System. iNaturalist is a website that is creating a “living record of life on Earth”, and relies on team members to post digital records such as photographs and sound files that document species in an area. Local naturalist Paul Bedell, along with VCU Rice Rivers Center’s Anne Wright, conducted the training session, which included both an introduction to iNaturalist and to our own James River Park System iNat project. Next, the group headed into the Park to photograph plants and animals; upon returning to Park Headquarters, participants learned how to prepare their images and post them to the website.

The participants are continuing to deliver many observations to the Park project, and their observations are recorded here: http://www.inaturalist.org/projects/james-river-park-system

Another training session will be held on Saturday, August 8 from 9-12 at Park Headquarters. For more information, contact abwright@vcu.edu.

Ms. Tenorio received her Masters in Aquatic System Ecology from the University of Antofagasta, Chile, and her Bachelors in Marine Biology from the University of Concepción, Chile.

Paul Bukaveckas, Ph.D. featured speaker at regional meeting

March 4, 2015

The Virginia Water Environment Association hosted Dr. Paul Bukaveckas at their February meeting as the featured speaker; he provided an update on the recent findings of the ongoing James River Chlorophyll-a Study. Dr. Bukaveckas chairs the Science Advisory Panel on this study, which has been tasked by DEQ to determine defensible criteria for chlorophyll-a that will protect water quality and prevent harmful algal blooms. The outcome of this study may have a significant impact on WWTPs and MS4s in the James River basin, as it will shed light on the appropriateness of the nutrient load allocation for the James River Basin.

The gravity of pollination

March 4, 2015

The VCU Rice Rivers Center congratulates Dr. Rodney Dyer and Dr. Angela Redwine on their publication, “The gravity of pollination: integrating at-site features into spatial analysis of contemporary pollen movement”, published in Molecular Ecology (2014).

The abstract reads as follows:

Pollen-mediated gene flow is a major driver of spatial genetic structure in plant populations. Both individual plant characteristics and site-specific features of the landscape can modify the perceived attractiveness of plants to their pollinators and thus play an important role in shaping spatial genetic variation. Most studies of landscape-level genetic connectivity in plants have focused on the effects of interindividual distance using spatial and increasingly ecological separation, yet have not incorporated individual plant characteristics or other at-site ecological variables. Using spatially explicit simulations, we first tested the extent to which the inclusion of at-site variables influencing local pollination success improved the statistical characterization of genetic connectivity based upon examination of pollen pool genetic structure. The addition of at-site characteristics provided better models than those that only considered interindividual spatial distance (e.g. IBD). Models parameterized using conditional genetic covariance (e.g. population graphs) also outperformed those assuming panmixia. In a natural population of Cornus florida L. (Cornaceae), we showed that the addition of at-site characteristics (clumping of primary canopy opening above each maternal tree and maternal tree floral output) provided significantly better models describing gene flow than models including only between-site spatial (IBD) and ecological (isolation by resistance) variables. Overall, our results show that including interindividual and local ecological variation greatly aids in characterizing landscape-level measures of contemporary gene flow.

VCU Life Sciences alum receives top honors for protecting Commonwealth waters

June 3, 2015

The Environmental Law Institute has announced that David L. Davis received the 2015 National Wetlands Award for State, Local, and Tribal Program Development. Mr. Davis and six other award recipients were honored at a ceremony at the U.S. Botanic Garden in Washington, D.C., on May 21, 2015.

A Virginia native who grew up fishing and clamming on Chincoteague Island, David L. Davis has over 25 years of wetlands experience. He majored in biology at the College of William and Mary, completed some graduate work in wetland science at the Virginia Institute of Marine Science, and completed a master’s degree in environmental policy and administration at Virginia Commonwealth University. He has gone on to play an essential leadership role in the evolution of Virginia’s wetland program. "Before 2000, Virginia did not have an independent wetlands program," said Davis. After several court decisions limited federal jurisdiction of wetland protection, Virginia decided that it should have a say in impacts affecting its wetland resources.

In 2000, Davis was appointed to serve on the Technical Advisory Committee for Virginia’s Department of Environmental Quality (DEQ), where he was tasked with drafting the Commonwealth’s new wetland regulations. A year later, he joined DEQ staff as a wetland ecologist, and ultimately became the Director of DEQ’s Office of Wetlands and Stream Protection in 2007.

Next month, after a more than 10-year effort, Virginia will be launching its Wetland Condition Assessment Tool (WetCAT). Under Davis’ leadership, Virginia has become a flagship state when it comes to wetlands monitoring and assessment, being one of only three states in the Mid-Atlantic region to have completed this effort. The web-based tool will allow the public to better understand the health and condition of Virginia’s wetland resources, as well as analyze the impacts of development and other wetland stressors.

“Throughout his professional career, Davis has shown the dedication, skill, and common sense needed to be an effective state wetland manager and to move the ball forward on wetland protection,” said Ellen Gilinsky, Senior Policy Advisor for U.S. Environmental Protection Agency’s Office of Water.

“I have worked very hard to collaborate, and the National Wetlands Award shows there is value in collaboration,” said Davis. “If we go to our separate corners then none of our problems are solved—no better economy and no clean water. I don’t accept the concept that the economy and the environment are mutually exclusive. It’s too easy to fall into that trap. You have to give up some things in order to get things done.”

Funds being raised will be used to build the much-needed Research Building, which will be comprised of laboratories, offices and other facilities. Planned laboratories include: Environmental Analysis, Atlantic Rivers Institute, Environmental Technology, Fish Conservation, James River Water Quality Studies, Wetland Restoration, Water Resources, and four Research Support Laboratories.

Founded in 1957 by Mr. Robert G. Cabell, III, and Mrs. Maude Morgan Cabell, the Cabell Foundation was established as a private, non-operating foundation to support the permanent needs of charitable organizations throughout Virginia, with particular emphasis on agencies in the metro Richmond region. Since its inception, the Cabell Foundation has provided permanent gifts and challenge grants to a diverse mix of nonprofit institutions. Mr. and Mrs. Cabell believed the Foundation should be responsive to human need in its deliberations and in taking initiative that would inspire the community to action. The intent of the challenge grant is that multiple, smaller donors would be moved to contribute to the supported cause — in this case, the construction of the research facility that will propel the Rice Rivers Center to the next level of significance and contribution to the global efforts of preservation and restoration of our natural resources and human health.

The mission statement of the VCU Rice Rivers Center reads, “The VCU Rice Rivers Center will be internationally recognized for its academic programs focused on scientific research, education and public outreach, and for informing public policy related to river ecosystems, their watersheds and the conservation of species that inhabit those watersheds.”

While this mission is already being met, the magnanimous support of the Cabell Foundation is helping to bring this mission to even greater fulfillment by propelling the generosity of the community at large. VCU Rice Rivers Center extends our hearty thanks.

VCU Rice Rivers Center receives $2.3 million gift from longtime benefactor Inger Rice

May 28, 2015

By Anne Dreyfuss

Inger Rice has made a $2.3 million gift to support the Virginia Commonwealth University Inger and Walter Rice Center for Environmental Life Sciences to fund a multibuilding overnight lodge and to contribute to the construction of a research laboratory on the property.

A $1.8 million portion of the gift will finance the construction of the overnight facility, which will have up to 30 beds where students and researchers will stay while they work at the living laboratory in Charles City County, Virginia. The other $500,000 will go toward the $6.7 million campaign to fund construction of a state-of-the-science building that will enable the scientists at the center to conduct all of their research and analysis on-site. Both buildings will be funded entirely by private resources.

“You can see it in a dream, but sometimes dreams don’t come true,” Rice said. “Now I will see the reality.”

For more than a decade, Rice has been turning her dream of housing a premier environmental research center at VCU into a reality.

In 2000, Rice gave 342 acres of land along the lower James River to VCU as a location for the university to build an environmental research and education center. In the subsequent 15 years, Rice has continued to financially support the center. In 2007, she donated $2 million for construction of the 4,900-square-foot Walter L. Rice Education Building, which is the first LEED platinum-certified building in Virginia. In 2009, Rice donated $1.2 million in recognition of the beginning of the tenure of VCU President Michael Rao, Ph.D., at the university and to establish the Inger Rice Endowment Fund, which supports maintenance of the center’s grounds and the education building.

“The internationally recognized environmental research conducted at the VCU Rice Rivers Center would not be possible without the continuous generous support from Mrs. Rice,” Rao said. “This latest gift will allow for VCU to continue to attract the country’s best scientists to our state-of-the-art facility, which will further enhance the quality of research and education at the center.”

Current research at the center includes highly recognized programs focused on analyzing water quality in the James River and helping to restore the federally endangered Atlantic Sturgeon in the river. The VCU Rice Rivers Center is also home to one of the most significant wetland restoration projects on the East Coast. The center stands as a leader in river ecosystem science, addressing pressing water resource issues vital to society and the natural environment.

“Mrs. Rice has again raised the bar on the research and education opportunities at VCU,” said Leonard Smock, Ph.D., interim vice provost, VCU Life Sciences, and director, VCU Rice Rivers Center. “With the lodge, students and scientists will be able to stay overnight at the center for days-to-weeks, becoming immersed in the science being conducted at the center and in the many classes and outdoor educational programs offered by center faculty and staff. We are very grateful for all that Mrs. Rice has done and continues to do for the VCU Rice Rivers Center.”

 

Land, sea and everything in between: Rice Rivers Center researchers present their work

March 10, 2016

By Anne Dreyfuss

Virginia Commonwealth University Rice Rivers Center researchers shared discoveries on everything from the fish that swim in the James River outside the building’s back door to the shorebirds that fly over the Atlantic Ocean off the coast of the West Indies during the center’s seventh annual research symposium on May 8.

Each year the symposium brings together faculty, students and researchers from cooperating universities, agencies and organizations to share the latest in conservation ecology and the environment. More than 100 people attended this year’s event at VCU’s 494-acre living laboratory in Charles City County for a day that included nine platform presentations, two short films and 15 research posters.

“One really nice aspect of the center is the number of students who get their feet wet in research out here,” said Leonard Smock, Ph.D., interim vice provost, VCU Life Sciences; director, VCU Rice Rivers Center. “There is no substitute for hands-on involvement in research.“

Throughout the day, students and faculty demonstrated the multitude of ways they are immersing themselves in research.

Environmental studies graduate student Jameson Hinkle discussed his exploration of new ways to track Atlantic sturgeon without having to catch the prehistoric fish. Hinkle is working on developing environmental DNA scanning tools that would be used to analyze sediments from the river that have sturgeon DNA attached to them, instead of analyzing the DNA directly from the fish itself.

“If we could get these methods to work we could save time, money, and risk and injury to the sturgeon,” Hinkle said.

Upstream, Daniel J. McGarvey, Ph.D., is studying 71 species of fish in West Virginia waterways. The VCU Center for Environmental Studies assistant professor presented findings from his graduate-level conservation biogeography class, which is tracking the combined threats of climate change and mountaintop removal mining on West Virginia fishes.

“Mountaintop removal mining is covering a very large chunk of the real estate in southern West Virginia,” McGarvey said. According to research from his class, a significant portion of fish species will have habitat quality decreases due to climate change in the upcoming years. As the fish swim upstream to escape the effects of climate change, they’ll be coming dangerously close to mountaintop removal mining sites, where the water will be uninhabitable due to coal mining byproducts.

Looking up — literally — Bryan D. Watts, Ph.D., presented on the progress he has made protecting shorebirds that stage in the mid-Atlantic.

Every spring the director of the Center for Conservation Biology, a unit within the VCU Rice Rivers Center, flies a small Cessna aircraft weekly along the outer edge of the East Coast barrier islands to count shorebirds.

“We fly low, get the shorebirds up, identify them and estimate numbers,” Watts said.

The data he collected on whimbrels showed that the birds’ population was declining by more than 4 percent annually in recent years. “This matches up fairly well with some surveys in North and South America which shows a similar decline rate,” Watts said.

In order to uncover the reason for the birds’ declining population, Watts and his research team outfitted 35 birds with solar-powered satellite transmitter harnesses. The harnesses allowed the researchers to track the birds anywhere on the planet.

Aided by the harnesses, the researchers discovered that whimbrels were being hunted in large numbers in the West Indies. “We think that is one of the primary reasons that the population is currently in decline,” Watts said. Now, Watts and his research team are working with policymakers for the 60 independent jurisdictions throughout the Western hemisphere where the birds fly to change hunting laws.

“We are having some success,” Watts said, adding that Guyana changed their hunting policy within the past month.

Closer to home, integrative life sciences Ph.D. student Benjamin Colteaux is studying whether the commercial snapping turtle harvest in Virginia is sustainable. Colteaux is working with the Virginia Department of Game and Inland Fisheries to assess the sustainability of snapping turtles under increasing commercial harvest pressure within Virginia waterways.

“The United States snapping turtle export has gone through the roof,” said Virginia Department of Game and Inland Fisheries herpetologist John D. Kleopfer, who presented Colteaux’s findings along with historical background. In the past decade, the commercial snapping turtle harvest in Virginia has increased 12-fold, mostly due to shipment to the Asian food market.

“We have a lot of folks around the country that are waiting for our results,” Kleopfer said. “This is the first project that has investigated this type of harvest in an open water coastal plain system.”

Throughout the day-long event it became obvious that the research conducted through the Rice Rivers Center, which has included more than $130,000 in funding for more than 100 students, extends far beyond the boundaries of the center’s Charles City County property limits.

“We as scientists can guide conservation. The problem is we can’t deliver it,” Watts said, echoing the sentiments of presenters throughout the day. “We have to have people along the way who buy into our message. They’re the ones who can actually deliver it in the long run. Without people in these different places, we can’t collectively protect these species. We’re seeing the rapid emergence of an eco-sociology. That is really the end-game of conservation.”

 

Yellow-crowned Night Herons Adjust to Changing Climate

May 18, 2015

VCU Rice Rivers Center collaborator: Center for Conservation Biology

By Bryan Watts

Over a span of only 50 years, the yellow-crowned night heron has shifted its breeding season by more than 20 days. A comparison between incubation dates collected in 2015 and dates collected decades earlier (1960-1969) reveals the shift in season. Birds are both arriving on the breeding grounds and laying their eggs earlier in the Tidewater region of Virginia.

Along the Atlantic Coast, the life of a yellow-crowned night heron is spent in pursuit of one thing: fiddler crabs. Their hunting times are scheduled around low tide when the crabs are accessible. They stalk fiddlers in the salt marsh and run them down on the mud flats. Females gorge on fiddlers to produce eggs, and breeding pairs feed the crabs to their young. Arrival of the herons on breeding grounds is timed exactly to when the crabs emerge from their burrows for the spring, and the herons' departure in the fall is timed to when the crabs return to their burrows for the winter.

Activity in fiddler crabs is very sensitive to temperature. When the temperature rises above 15°C (59°F), they emerge from their burrows and become active. Crabs retreat to their burrows and move underground when the temperature drops below 15°C. The date in spring when temperature passes the 15°C threshold is advancing, extending the season of fiddler availability. Yellow-crowns appear to be adjusting to the shift in season.

The 2015 season is the first of a multi-year study to compare the breeding ecology of the yellow-crowned night heron to a study conducted within the same colonies in the 1960s. The ten-year dataset from the 1960s was collected by Constance DuPont Darden. Mrs. Darden (former first lady of Virginia) was passionate about yellow-crowns, and her information has contributed a great deal to our understanding of the species. Her dataset is housed within The Center for Conservation Biology.

Climate change is a change in the statistical properties of the climate system over long periods of time. Regardless of the underlying causes of this change, the earth has been experiencing a documented shift in climate for decades. How wild species respond to changes in climate will determine many aspects of their ecology, including their geographic distribution, the timing of significant events in their annual cycle and for some their survival. Understanding the implications of these shifts is a growing focus of conservation biology. Because of both their migratory status and specialized diet, yellow-crowned night herons represent a model system for investigating how species respond to a changing climate.

Grad student Morina receives sea grant research fellowship

May 8, 2015

In a very competitive field, VCU researcher Joseph Morina has received one of only eight prestigious grants for 2015-2018 from the Virginia Sea Grant. Working in the lab of Dr. Rima Franklin, Morina will use the award to study microbial nitrogen cycling at the VCU Rice Rivers Center and other tidal wetlands in the Chesapeake Bay watershed. The award is $80,000 to cover three years of research.

Additionally, Mr. Morina was awarded a Rice Rivers Center Scholarship as an undergraduate and will be receiving an additional one this year for his Master’s work. VCU congratulates Mr. Morina on his hard work and excellent results thus far.

Accomplished student researcher wins prestigious grant

April 28, 2015

Alice Besterman thought she would be an anthropologist, but she was wrong. Her curiosity simply took a different turn.

Early in her studies at VCU, she transitioned to pursuing a B.S. in Environmental Science and quickly became immersed in ecological research. She participated as a student in the Panama Avian Field Ecology class in 2011, and from that experience became deeply interested in field ecology and avian research. Under the guidance of Dr. Lesley Bulluck, she conducted an Independent Study, the goal of which was to examine how caterpillar prey resources might affect Prothonotary Warbler reproductive success. Simultaneously, Besterman developed an interest in wetland ecosystems (thanks in part to taking Wetland Ecology) and pursued opportunities in wetlands research, including interning as a hydrologic technician for the U.S. Geological Survey.

After graduating from VCU, she enrolled at the University of Virginia, and is currently a first-year Ph.D. student, working in Dr. Michael Pace’s lab, seeking ways to integrate her interests in birds, wetlands, and ecosystem processes. Following up on previous graduate students’ work, she currently is interested in addressing the effects to mudflat ecosystems caused by an invasive seaweed, Gracilaria vermiculophylla. This invader proliferates on tidal flats throughout the barrier island/lagoon system along the eastern shore of Virginia. Previous work has found that this macroalga is associated with increased numbers of benthic invertebrates, as well as higher concentrations of pathogenic strains of Vibrio bacteria. Vibrio can become concentrated in the meat of filter-feeding molluscs, and so can pose a health risk to shellfish consumers. For her dissertation she is interested in investigating how the changes to the spatial dynamics of benthic invertebrates caused by this alga may lead to upward cascading effects for shorebird feeding, possibly resulting in changes to Vibrio abundance and distribution.

Recently, Besterman was awarded a fellowship from The National Science Foundation Graduate Research Fellowship Program (often abbreviated NSF GRFP). This program awards students early in their graduate careers with stipend and educational funds. Submissions must include a research proposal and also a personal statement describing the applicant’s interest in science, background, and future goals. Around 2,000 awards are given out each year across all fields of science. The fellowship provides $34,000 per year of stipend money given directly to the fellow, and $12,000 per year of educational costs for three years. Fellows also qualify to apply for NSF grants that foster professional development and research opportunities, such as internships with federal agencies and international collaborations.

VCU Life Sciences, the VCU Center for Environmental Studies and the VCU Rice Rivers Center all congratulate Ms. Besterman on her accomplishments and look forward to seeing the results of her ongoing research.

 

Nuturing a flame in Panama

March 10, 2015

By Bryan Watts, Center for Conservation Biology

When all of the high rhetoric of the day is packed away, conservation is about simple acts. It is about people deciding to make a better place for other species. It is about committing to the long path with your eyes fully open to the fact that much of the world is on a different path. It is about sustaining the level of passion required to prevail against whatever comes. In almost all situations, local people and organizations perform the simple acts that collectively hold the line.

In the fall of 1997 when The Center for Conservation Biology conducted a baseline study to investigate waterbirds in the Bay of Panama, the Panama Audubon Society was primarily a close community of bird watchers focused on documenting the avifauna of this incredible country. In the years following our findings that the upper Bay of Panama supported one of the most significant concentrations of waterbirds in the world, Panama Audubon transformed itself and assumed the responsibility for protecting the local ecosystem on which the waterbirds depend.

Over nearly twenty years as government administrations, agencies, corporations, and varied socio-economic trends have threatened the habitats that undergird the system, Panama Audubon has stayed the course and championed the cause of waterbird conservation. Led by dynamo Rosabel Miró, the small group has faced down a never-ending parade of challenges to become an international force for waterbirds. In a time when so much attention is given to tinsel and lights, the group represents the essence of what conservation should be.

The Center for Conservation Biology continues to support the Panama Audubon Society and efforts to protect the upper Bay of Panama for waterbirds. Our current focus is in helping to build the local experience and capacity needed to work directly with shorebirds. To this end, The Center has sent a team of shorebird biologists to work side by side with Panama Audubon staff for short periods during the past two winters (Shorebird dawn in Pacora).

In early March of 2015, Bart Paxton and Fletcher Smith spent time training staff and volunteers of Panama Audubon on field techniques. On menu was training in bird capture, bird handling, bird banding, and surveys for flag resighting. With each experience, staff members have become more proficient in field techniques. Our belief is that local training will lead to the establishment of an experienced field team capable of executing field projects and training new generations of waterbird biologists that will continue the growing legacy of waterbird conservation.

The Canadian Wildlife Service was a partner in the 2015 effort and we thank them for their continued support of shorebird conservation.

OspreyWatch returns for its fourth year

March 25, 2015

VCU Rice Rivers Center collaborator: Center for Conservation Biology

The osprey are returning to the Northern Hemisphere this month and beginning to repair nests and reconnect with their mates. The Center for Conservation Biology’s OspreyWatch program is in its fourth year organizing citizen scientists to collect data and make observations about breeding osprey. In 2014, the project monitored 1,538 nests on three continents through the efforts of over 1,800 volunteers and researchers.

Volunteers collect data including the date when adults first arrive back at the nest (if the pair is part of the migratory population), the date that eggs are laid in the nest, the number of young seen, and the date the young successfully fledge. OspreyWatch volunteers also document the fate of nests that fail due to storm damage, nest predators (raccoons and owls), human caused nest destruction, or nest abandonment, which is important in helping researchers determine nest failure rates. Data collection on a large spatial scale enables osprey researchers to see broad trends in breeding chronology and breeding success.

OspreyWatch has helped facilitate data collection for researchers and citizen monitoring groups in Ontario, New Jersey, Florida, South Carolina, Massachusetts, Virginia, and California. The LowCountry Institute in coastal South Carolina joined OspreyWatch in 2013 and uses the website to coordinate 22 volunteers monitoring 420 nests (read their 5-yr study report). Contact program manager Libby Mojica at osprey@osprey-watch.org if your citizen science group would like to join as a monitoring group.

Rappahannock eagles beat expectations

March 20, 2015

VCU Rice Rivers Center collaborator: Center for Conservation Biology

By Bryan Watts

When bald eagle surveys were initiated in the Chesapeake Bay during the late 1950s and early 1960s, the Rappahannock River was not a standout. Compared to the historic James and Potomac Rivers, the Rappahannock was not as well known to the public. In terms of eagle numbers, the river was overshadowed by the DDT-era strongholds of the upper Potomac, the lower James and the Blackwater. But one has only to look over a map of the tributary to recognize the bones of a thoroughbred. The Rappahannock flows through a landscape that remains relatively low on development and high on natural beauty. The creeks, bluffs, marshes, and meanders combine to make one of the most attractive locations for breeding eagles in the Chesapeake region, and over the past two decades the river has come into its own.

Recovery of breeding eagles along the Rappahannock has been dramatic. By the early 1970s the population had been reduced to six known pairs and the long-standing pair along LaGrange Creek near Urbanna had not produced a single young in ten years. Most of the pairs were located in the lower, salty reach of the river. Over the next twenty years productivity improved, the population increased to more than 50 pairs and birds began to occupy many of the landmarks that today represent hallowed ground. Fones Cliffs, Cat Point Creek, Payne’s Island, Owl Hollow, and Portobago Bay over time have become synonymous with bald eagles in the Chesapeake Bay. Since the early 1990s, the Rappahannock has bloomed and now supports one of the densest breeding populations found anywhere throughout the species range.

The 2015 early survey that includes the Rappahannock was completed on 12 March and documented 219 breeding pairs. Over the past 40 years, eagles have poured into the less salty parts of the river. The 25-mile (40 kilometers) reach of the river just above Tappahannock now supports an incredible 90 pairs. Three locations within this reach support two eagle pairs nesting within 100 meters of each other. Tolerance of territorial neighbors to this degree was never imagined in the early days of the survey and is a testament to the high availability of prey.

Although impacted by the treatment of agricultural lands during the “living better through chemistry” period of recent history, the Rappahannock is now one of the jewels of the mid-Atlantic region. Protection of conservation lands within this watershed will continue to provide a great return on investment.

Midnight Run: Nightjar Survey to Begin 9th season

March 10, 2015

VCU Rice Rivers Center collaborator: Center for Conservation Biology

By Michael Wilson

Nine years ago The Center for Conservation Biology implemented a national survey program intended to close a significant data gap on the health of North America's nightjar populations. Nightjars are a group of nocturnal species that include nighthawks, whip-poor-wills, common poor-wills, and chuck-will’s-widows, among others. These species had been widely ignored by other national bird survey programs for the simple reason that those programs target species active during daylight. Prior to implementing the nighttime survey focused on nightjars, there was a general belief that nightjar populations were declining based on anecdotal reports and stories shared by many people who now conduct annual surveys.

Over the past nine years, the Nightjar Survey Network has been able to provide information that is critical to the conservation of these species. Some examples include gaining a better understanding of the relationships between nightjar abundance and regional landcover, defining distribution of the Mexican Whip-poor-will in high elevation habitats in Arizona, and providing benchmarks throughout the country to compare population changes into the future. Nightjar survey data collected in Florida will now be implemented into the Florida Breeding Bird Atlas to help bolster their effort to document state-wide occurrences.

Dates for the 2015 survey have recently been chosen. These dates are specifically selected to coincide with the nights of brightest moonlight and greatest Nightjar calling frequency and are standardized to specific regions. Visit the Nightjar Survey Network website to see available routes, survey instructions, and data summary.

Special thanks to all past and returning participants for your years of support and we hope to welcome many new volunteers for the 2015 season.

2015 Survey Dates:

Window 1: 25 April to 11 May, 2015 for low elevation AZ and NM, and FL and TX
Window 2: 25 May to 9 June, 2015 for any location in the country
Window 3: 24 June to 8 July, 2015 for areas north of AZ, FL, NM, and TX and recommended for high elevation areas in the Northern U.S.

Cameras record the often hidden lives of wildlife

March 10, 2015

Otters
View the video on richmond.com »

James River Park is a great place to play, picnic and hang out.

And that’s just for the animals.

Unbeknownst to visitors to the mostly wooded, roughly 600-acre park, creatures big and small enjoy a largely hidden life nearby.

“It’s mind-boggling how many different animals live in or move through that park,” said Virginia Commonwealth University biologist Anne Wright.

Wright knows. As producer of the Science in the Park website, she leads an effort to document the park’s wild denizens using hidden video cameras and footage taken by parkgoers. The project began last spring.

Creatures caught on video, often at night, include river otters with youngsters, a beaver chowing down, a muskrat with furlike hair highlights, a deer with fawns — even some rarely glimpsed mink.

“This is telling everybody: Hey, the park looks like nobody’s there, but that’s probably because you’re running and screaming and jumping around. …It’s hard to see animals,” Wright said.

The Science in the Park website is a section within the Friends of James River Park site. The science site is an effort of VCU, the Friends group and the city park, among others.

Launched in 2013, Science in the Park delves into the park’s geology, plants and other natural attractions. To document the park’s wildlife, Wright worked with volunteers and some paid helpers funded through a corporate grant. They lashed six cameras to trees in hard-to-spot places near footprints, animal trails and slick spots where otters had slid into water.

One inspiration for the project, Wright said, was a report from paddler Scott Anderson that he was seeing otters — sleek and playful animals spotted in the James before, but not often.

Anderson said by phone that he saw otters three or four times this past summer while he was paddling around sunrise between the Huguenot Bridge and Pony Pasture Rapids in South Richmond.

Once, Anderson and a friend paddled alongside an otter family — “probably three adults and maybe two babies” — then followed the animals when they hopped up on land.

“We were checking them out, and they were checking us out. It was real cool, because they weren’t scared. They were just like, ’What are these people doing up here?’”

Anderson worked with Wright to put a camera near the site, and the otters were captured on video.

The park is a system of mostly wild lands in and along the James. It is the region’s biggest attraction, drawing each year more than 1 million walkers, paddlers, swimmers and others.

Wright, outreach director for VCU’s Rice Rivers Center, has been visiting the James in Richmond for 40 years.

She said she was shocked to find “an absolute wildlife corridor” on an island near Reedy Creek in South Richmond. A camera recorded otters, a ground hog, a muskrat, raccoons, deer, a beaver, a red fox and a chipmunk.

Probably the biggest surprise of the project was the finding of mink, a member of the weasel family that can spray like a skunk and purr like a cat. Mink showed up at Pipeline Rapids near Shockoe Slip and near Reedy Creek.

Wright didn’t want to be specific about the places animals were found, for fear that people might disturb them.

To see wildlife, she said, “you kind of have to become a nature lover. Get a pair of binoculars.”

Mink

Wright said she wants to recruit local “eyes and ears” to report wildlife sightings.

Three nature walks will groom people for that effort. The first will be held May 16 from 9 a.m. to noon, starting with a talk at the park’s headquarters at Reedy Creek. Local naturalist Paul Bedell will lead the program.

As Wright checked some of the wildlife videos in her darkened VCU office, it was clear she adored her subjects. “There he is, that little goober,” she said while viewing a groundhog waddling to the river. Watching a fawn, she said, “What a cutie, going after Mom.”

The project shows the health of the James and the value of the park as a wildlife habitat, Wright said.

Should park visitors worry about sharing space with animals?

“I would say you would be extremely lucky if you came across any one of these animals, except for a great blue heron or a Canada goose,” Wright said. “Be glad. Whip your camera out.”

The wildlife project will continue, Wright said, as long as it continues to be interesting.

“I haven’t caught coyote, which I think we do have in the park,” she said. “I still think there are some things to find out.”

She added, “It would be cool to get a bear. …If deer can move around, so can bear.”

We can only hope.

Rare father-daughter pairing in eagles from Norfolk Botanical Garden

March 13, 2015

VCU Rice Rivers Center collaborator: Center for Conservation Biology

By Bryan Watts

Unlike in ancient royal dynasties like the Egyptian Pharaohs or Persians for whom inbreeding was a strategy for sustaining political power over the centuries, breeding with close relatives is rare in wild animal populations. Mating with second cousins or distant relatives may be common, particularly in small populations, but close inbreeding - the mating of full siblings or parents with offspring - has been rarely documented. Close inbreeding leads to inbreeding depression, or a reduction in fitness (ability to survive and reproduce) related to the accumulation of deleterious recessive genes. For this reason, most species have developed inbreeding avoidance mechanisms that reduce the likelihood that close relatives will ever mate. In most raptor species, young disperse substantial distances from the natal territory, greatly reducing the likelihood of future pairings between parents and offspring. In addition, dispersal distance (distance between hatching and breeding locations) is frequently twice as far for females compared to males, making pairings of full siblings unlikely. In a recent paper examining dispersal distances in bald eagles by Brian Millsap and other authors, dispersal of females averaged 138 kilometers (86 miles) whereas males averaged only 59 kilometers (37 miles).

In a rare event, the adult male from the famous Norfolk Botanical Garden nest, followed by thousands of nest cam viewers from around the world, is raising a brood with a female that he produced and raised in 2009. The female, named “HE” after the alpha code on her purple band, is one of three young raised by the male in 2009 that was banded as a nestling by The CCB. Having just reached reproductive maturity, this is the first breeding attempt by HE. Surprisingly, the nest that she built with the male is only 1.6 kilometers (1 mile) from the nest where she was raised. Her extremely short dispersal has led to the unusual pairing.

The old male is not banded but has a distinctive black inclusion in his left iris that allows for positive identification. He has held a breeding territory around the Norfolk International Airport since fall 2003. On 12 April 2011 the breeding female of the original pair was struck by a jet and killed. Since that event, many females have passed through the territory attempting to set up house, eventually leading to the successful establishment of HE.

HE was hatched on 21 March 2009 and fledged on 8 June 2009. Her siblings were HH (named “Azalea” and tracked for over 3 years by satellite transmitter) and HK (now with his own breeding territory in Virginia Beach). The entire brood has remained surprisingly close to their natal territory near the airport, making only brief forays outside the lower tidewater area.

Close inbreeding is difficult to document in wild populations because it requires the marking of individuals such that they may be tracked through time and monitoring to document adult pairings. However, even within intensively managed and marked populations, the occurrence of close inbreeding is rare. Within the mid-Western population of peregrine falcons, only 5 occurrences of close inbreeding were documented in more than 450 pairings. These included 3 pairings of full siblings and 2 pairings of adults and offspring. Interestingly, the pair of peregrines that nested on the James River Bridge in Newport News, Virginia, between 1994 and 2006 nicknamed “Virginia” and “James” were full siblings produced on the Leg-Mason building in Baltimore, Maryland. The pairing was one of the most successful peregrine pair ever documented.

The effect of urbanization on egg parasitism levels in the fall cankerworm

March 4, 2015

By Derek M. Johnson, Assistant Professor, Biology, VCU and Abby Nelson, Master’s Student, Biology, VCU

Insect outbreaks are the primary cause of large-scale natural disturbance in North American forests. Defoliation by insects has been shown to decrease tree growth, increase tree mortality, and have significant effects on forest ecosystem processes. Global changes due to human activities have been proposed to result in more frequent insect outbreaks. The fall cankerworm (Alsophila pometaria) has recently increased in the frequency and scale of outbreaks in eastern Virginia. The recent increase in fall cankerworm outbreaks in eastern Virginia from 2012-14, and the 10-20 years of damage this moth has done to trees in Charlotte and Raleigh, North Carolina, begs the question of whether urbanization plays a role in these outbreaks.

Anyone who has spent time under Richmond’s urban and suburban trees in the spring of the last three years has encountered high densities of inchworms, the larval stage of fall cankerworms, on their cars, homes, clothing, and just about anywhere else imaginable. The fall cankerworm feeds on a broad range of deciduous tree species and has one generation per year. The adults emerge from the ground in late fall or winter to mate. Females are flightless, thus must climb the trunks of trees in order to oviposit their eggs in the forest canopy. The eggs overwinter and hatch in the spring. A suite of parasitic wasp species attack fall cankerworm eggs and may play an important role in suppressing populations below outbreak levels. Parasitoids have been shown to be particularly susceptible to pollutants, and forest fragmentation may restrict the movement of these tiny wasps; thus, we hypothesize that urban effects reduce either the abundance or species richness of fall cankerworm parasitoids, and this indirectly causes longer, more frequent, and more severe outbreaks in urban areas compared to rural areas around Richmond.

In particular, we are studying the effects of human population density and forest fragmentation on the population dynamics of fall cankerworms and their parasitoids. We have banded trees in 15 sites (including the VCU Rice Rivers Center) in and around Richmond with a sticky substance called Tanglefoot® to trap and count females as they try to climb the trunk. The sites represent a range of human population densities and levels of forest cover. This study will provide important information towards understanding why fall cankerworms are becoming more of a forest pest in recent years. More broadly, this study will provide information on how urbanization may affect pest population dynamics in a rapidly changing world.

Childhood dream comes true with help of VCU

March 4, 2015

Jenna Dodson has known she wanted to be in the Peace Corps since fifth grade, when she came to understand the need for help in places not as affluent, specifically Africa. Following high school, and having received the Provost Scholarship from VCU, she settled into an environmental studies major during her freshman year. According to Dodson, “It ended up being the perfect choice, as I continued to learn about the growing problems of today’s world, both environmental and economic, and the incredible gap between first and third world countries.

Dodson has taken advantage of the many opportunities presented to her at VCU, including the ISEP Exchange program, and in the spring of 2012 studied abroad at Massey University in New Zealand. Upon returning from New Zealand, she began working at the Campus Learning Center as a biology/chemistry tutor, continuing to develop her teaching skills. The next summer, she was awarded an Undergraduate Research Opportunities Program (UROP) Summer Fellowship and began exploring her interest in research by working on the Prothonotary warbler project, an ongoing, international research initiative based at the VCU Rice Rivers Center.

This led to Dodson’s pursuit of a Master of Science in Environmental Studies through the accelerated program where her thesis research under Dr. Lesley Bulluck addresses foraging and breeding ecology of Prothonotary Warblers. She was given the opportunity to participate in the Panama Avian Field Ecology course two years in a row, the first year (2013-2014) as a student, and the following year (2014-2015) as a teaching assistant. In the first semester of this year, Dodson was a teaching assistant for Earth Systems Science, and this semester is a teaching assistant for Panama Avian Field Ecology and Oceanography. In addition to her assistantships, Dodson transitioned from tutoring undergraduates to improving literacy in a second grade elementary school classroom through VCU AmeriCorps. Dr. Bulluck adds what Dodson does not volunteer, “As an undergraduate, Jenna also was a music minor and captain of the VCU women’s crew team…all while maintaining a 4.0 GPA.”

Dodson notes, “All of these opportunities VCU provided along the way have allowed me to further my education, further develop my teaching and leadership skills with a wide student demographic, and solidify my passion for communicating science, creating a perfect foundation for an Environment Sector Peace Corps volunteer.”

Beginning in September of this year, Dodson will be an Agroforestry Extension Agent in Senegal, West Africa for a 2 year, 3 month term of service. Her main role will be to increase food security by focusing on the establishment of multi-purpose tree species, fruit tree propagation and orchard management. She will be organizing formal trainings, one-on-one instruction, and demonstrations that assist local farmers to acquire the technical skills they need to establish their own tree nurseries and out-plant the seedlings produced.

VCU congratulates Ms. Dodson on her hard work and achievements, and we wish her well in her new role.

 

Dancing with the Dragon

March 2, 2015

VCU Rice Rivers Center collaborator: Center for Conservation Biology

By Bryan Watts

Leonardo da Vinci describes the duality of the research experience as standing before the mouth of a grand, unexplored cavern. Peering into the black, one is simultaneously struck by the sweet anticipation of discovery and the fear of the journey. Not a fear of the unknown itself but the fear of losing yourself to the journey, or just the opposite, the fear of becoming the bleached piece of driftwood thrown up so high on the beach by a storm that you may never feel the caress of water again.

For those of us who have grown up in the bird world, sometime in our late teens, the questions that occupy our days undergo a seismic shift. Our obsessions with learning plumages and subtle song dialects drift into the backwater. New questions begin to appear from nowhere. Why is the home range of one species four times larger than that of another? Why does this bird migrate thousands of miles while this one stays home? Why do birds that nest in cavities incubate so much longer than those that nest in the open? And what is up with some females that must chase males with the longest tails or the bluest legs or the loudest song? These new questions are those of an explorer standing on the shoreline of an immense sea. It is our first encounter with the dragon. Like Steinbeck, he is shouting, “Thou mayest”, and the choice is laid out before us to set sail on a life of research or stay safely moored in the harbor. In the end, either we choose to splash and play in the shallows or, as Dylan says, we dive deep and marry the mermaid.

At this early age, the raw energy burns white hot and consumes everything in its path. Like a flood in the headwaters moving rocks and ripping out trees, the powerful wave of questions runs over us. We are unsure of our path and destination. We lack the foundation and discipline to order the questions in meaningful ways. But despite the uncertainty and the mayhem, we are miraculously transformed into the cock of the rock. We feel the universe has bestowed upon us a unique insight. Our world is painted in black and white. We proclaim that we have solved the great mysteries and describe the dragon in vivid detail. The old ones look on with compassionate eyes but say nothing. We do not know at this young age that the real questions are far downstream. We will have to run the rapids to have any hope of reaching them.

The questions are relentless and they become our constant companions. Night after night we lie awake contemplating strategy, sending our mind down so many promising avenues that under scrutiny lead to dead ends. We move knight to queen’s bishop 3 only to be countered. We order a battalion around the left flank only to be cut off near the river by a full regiment. Like the second labor of Hercules with the hydra, each time one question is answered two more appear in its place. The defeats are enough to shrink any cock of the rock down to a chirping sparrow. But over time we begin to understand how to effectively approach questions, we gain strength, the dragon gives ground and knight takes queen. Time in the rapids has taught us the hows and whys of research.

By the time we finally enter the flat water, we have gained purpose and direction. We know which research questions are worth pursuing and how to exploit the soft underbelly of their defenses. We have become high disciples of the scientific method. We get to work. We stand high on the hill and orchestrate our troops. We cut a wide swath across the landscape, taking minimal casualties. We stack up victories like cordwood for the Arctic winter. In our swagger we believe that we have mastered the dragon.

The revolutionary Princeton ecologist Robert MacArthur was noted for stating that any experienced bird watcher could walk into a habitat and tell you which birds would be found living there, but if we did not quantify, analyze and interpret their distribution, the patterns would continue to be sensed without ever being communicated effectively to future generations. He was right. But after thousands of questions and years on the battlefield, we begin to contemplate the broader meaning. Inevitably, we reacquaint ourselves with the dragon. We begin to recognize that there is a limit to how far numbers can take us, that there is a point along this journey beyond which investigations cease to provide any traction. What we can measure and prove provides only the black-and-white skeleton of a broader reality. The fresh, changing picture of a species with all of its vibrant color belongs to an infinitely larger domain beyond the reach of numbers. All of our experiences tell us that mystery is an essential element in the dance between what we know and what we don’t know. Mystery is not something to be conquered but something to be savored. Without mystery there is no exploration.

The new peace accord with the dragon represents the end of one journey and the beginning of another. We look around to see that we have passed out of the river mouth and have entered the immense sea near the shoreline where we stood as a teen. Now surrounded by cock of the rocks, we say nothing. We recognize that every riffle and pool along the way is precious and anyone who musters the courage to leave the harbor is entitled to his own journey. Ours is just beginning anew. This time we carry not only the curiosity of a child but an experienced mind left open to mystery.

T.S. Eliot was right in East Coker, “old men ought to be explorers”.

A day of Ipswiching

February 11, 2015

By Bryan Watts, Center for Conservation Biology

The subdued color palette of this habitat is reminiscent of west Texas. Although the exposure to heat and the lack of water during the growing season have shaped the plant community in a way similar to Texas, the smell of the Atlantic just over the dunes and the sight of willets and dunlin rising and falling over distant mudflats give a clue that we are nowhere near El Paso. We are on Metompkin Island in the dead of winter walking south through a large patch of dune grassland. Despite its proximity to the major resort towns of Virginia Beach and Ocean City, Metompkin is wild. Jointly owned by The Nature Conservancy and the U.S. Fish and Wildlife Service, the island has no engineering structures that impede its movements. Here, water and sand are free to perform their give-and-take dance as they have always done. The result is a natural gem.

Fletcher Smith and I have come here to check on one of the beneficiaries of this wild stretch of coastline, the Ipswich sparrow. With us are long-time members of the Royal Society of Bird Sages Harry Armistead, Ned Brinkley, and Bob Anderson, and younger birders Ellison Orcutt and Zak Poulton. The Ipswich is a true coastal sparrow, spending its entire life cycle in dune habitat along the Atlantic Coast. Its breeding range is restricted to Sable Island off the coast of Nova Scotia, Canada, where it nests in dune and heath habitat. Its primary winter habitat includes coastal barriers and beaches along the Atlantic Coast. The global population is estimated to be only 6,000 individuals. Although breeding habitat on Sable Island is secure, winter habitat for this specialized sparrow is threatened by sea-level rise, coastal development and our insatiable desire to walk along the beach.

In a broad survey of distribution during the winter of 1971, Wayne Stobo and Ian McLaren determined that the Ipswich’s center of abundance during the winter season fell between Virginia and New Jersey. A survey conducted by The CCB in 2012 placed the Virginia bullseyebullseye right on the south end of Metompkin Island. During that winter, we recorded nearly twenty birds per kilometer of island here. The birds use areas with a diverse topography where storms have disrupted the dune line and where bunches of grass and seaside goldenrod provide both seeds and hides. Their distinctive, dune-colored plumage is a direct match to the habitat. Watching the birds work through the habitatsand, there is no question that they belong here.

We have come today to check on numbers and to do some banding in preparation for more focused efforts in future winters. We have not checked on the birds since the survey of 2012. Although a considerable body of literature has been published on the breeding grounds, very little is known about the winter ecology of this dune specialist. Several questions that are important to the future of this population remain unanswered. Which habitat attributes are critical during the winter? How may critical habitat components be impacted by sea-level rise and coastal change? How high is site fidelity?

We work only the northern two kilometers of habitat and turn back to reach the boats before they are stranded by low tide. We encountered 25 to 30 Ipswich sparrows within the short section of habitat and banded eight. We leave with a sense of confidence that this site will be an ideal venue for unraveling the winter ecology of this unusual form.

Paul Bukaveckas, Ph.D., continues to press for answers

August 19, 2015

Dr. Paul Bukaveckas has produced a prodigious amount of research this year, providing invaluable data to help understand and manage the worldwide problem of algal blooms.

As an aquatic ecologist whose research addresses basic and applied aspects of material and energy cycling in ecosystems, he focuses on two interrelated research topics: (1) the processes that regulate photosynthetic production in diverse aquatic habitats and (2) the role of primary producers in carbon and nutrient cycling. Current projects examine the interplay between hydrologic and ecological processes in flowing waters (streams, rivers, estuaries). The goal of this research is to address basic questions in ecosystems ecology that are important to understanding human impacts on aquatic resources.

Below is a listing of his most recent publications:

Agencies internationally are relying partially on Dr. Bukaveckas’ expertise to make impactful decisions with regard to water management, including the Department of Environmental Quality, which is using Dr. Bukaveckas’ research findings to help inform new guidelines for the TMDL for the Chesapeake Bay.

 

Another Crowned Eagle Lost to Electrocution

April 5, 2016

By Bryan Watts

On 6 March, 2016 we began to get an indication that a critically endangered crowned solitary eagle carrying a satellite transmitter in Argentina may be in trouble. The transmitter was stationary and its battery level was falling. On 15 March, José Sarasola traveled 1,300 kilometers to the last coordinate near San Luis and found the bird under a power pole. The bird named “Mahuida” by the Buenos Aires Zoo had been electrocuted. 

Mahuida is the fourth eagle included in the crowned eagle tracking project to be electrocuted in as many years. Electrocution of raptors is a global conservation problem. Birds are electrocuted either by perching on poles and touching their body parts to conductors and completing a circuit, or by flying into two lines and completing a circuit. Within open landscapes power poles offer attractive hunting or loafing perches and are used by many bird species. These same poles represent death traps when electrical suppliers do not use avian-safe practices. Avian-safe practices were developed by the power industry decades ago but have yet to be implemented in many areas. During 2012 CECARA, the Center for the Study and Conservation of Birds of Prey of Argentina (Centro para el Estudio y Conservación de las Aves Rapaces en Argentina) surveyed 3,114 power poles within a 12,000 square-kilometer area and found five dead crowned eagles. All poles associated with mortalities had “jumpers” or connecting wires above the pole crossbeam, a configuration that is not avian-safe. Such poles represented only 2% of those surveyed.

The crowned solitary eagle has an estimated global population of well below 1,000 individuals, is classified as endangered on the IUCN Red List, is included on the threatened lists of both Brazil and Argentina, and is presumed extirpated in Uruguay with no reported sightings since 1933. The species has a very low reproductive rate and so has a correspondingly low capacity to absorb mortality (read about sustainable mortality limits).

Evidence is mounting that mortality factors such as electrocutions and shootings are playing a significant role in the observed declines of this charismatic species.  We know how to prevent pole electrocutions.  Poles that represent death traps need to be retrofitted to comply with avian-safe practices throughout the breeding range of the crowned eagle.

Turtle population study aims to prevent population collapse

March 4, 2015

The global market for turtles has been increasing since the overharvest and collapse of Asian turtle populations, and snapping turtles are being harvested worldwide in unprecedented numbers to meet increasing international demand for turtle meat. Benjamin Colteaux is an Integrative Life Sciences Ph.D. candidate in Derek Johnson’s population ecology lab; his research focuses on assessing the sustainability of snapping turtles (Chelydra serpentina) under a range of historic and predicted commercial harvest pressures. Colteaux’s work examines snapping turtle populations in three Virginia waterways, each of which has experienced a different level of historic harvest pressure. By combining the data collected via mark/recapture, toxicology, radio telemetry and state and federal harvest/export records, Colteaux hopes to create a clearer understanding of the current state of snapping turtle populations in the U.S. The data collected from this study will allow for the assessment of current harvest regulations and highlight the potential benefit that adding new regulations, such as size limits, could have in snapping turtle management.

Rice Rivers Center lands artist-in-residence

February 27, 2015

Beginning next September, the VCU Rice Rivers Center will have its very own artist-in-residence: VCU Arts professor, Laura Chessin. During her residence, she will complete a range of writing, photography and film projects. These will include a documentary film to assist in the public outreach and educational mission of the Center, as well as a personal body of work to continue her exploration of the intersection of arts and design to engage audiences in a dialogue about how humans relate to the natural world. Ms. Chessin has been engaged with the Rice Rivers Center for some time now; one successful collaboration has been with Dan McGarvey, Ph.D. on their science and communications course, eESP 2.0, now in its second year. Another dynamic project has been her engaging work in Panama with instructors Cathy Viverette and Lesley Bulluck, Ph.D. “I’m grateful and excited by this opportunity to help expand the possibilities for the Rice Rivers Center to be a research center, as well as a place for creative interactions to gain a deeper understanding of, as Dr. Smock writes, ‘the beauty, fragility, and innate complexity of our natural world’.”

eESP 2.0 produces tangible results

February 2, 2015

CES Faculty member Daniel McGarvey and CES graduate student Christopher Mason recently published the first “results” from Daniel’s Quest-funded project, Ecological and Environmental Perception version 2.0 (eESP2.0). The manuscript, entitled Re-envisioning the Communication of Our Science, ran as the cover story in the first issue of the newly redesigned ASLO (Association for the Sciences of Limnology and Oceanography) Bulletin. This included a custom layout for the cover of the Bulletin in addition to the lead feature story. In the manuscript, Daniel and Chris relate the motivation and initial outcomes of the eESP 2.0 project, including examples of student work from the first graduate class offered under eESP 2.0 (Infographics – the Design of Scientific Information). The overarching goal of the project is to create a new graduate training curriculum that will help students to better illustrate and communicate their work, taking advantage of digital media outlets that have not traditionally been utilized by scientists.

Thomas Huff, who helped launch VCU Life Sciences, dies at age 62

February 2, 2015

Thomas F. Huff, Ph.D., who as vice provost for life sciences and research at Virginia Commonwealth University led VCU’s march into the age of genomic research, died Saturday. He was 62.

Huff was named vice provost in 2001, charged with putting VCU at the forefront of U.S. universities preparing students in the new fields of the biological sciences that had opened through research to sequence the human genome. Life Sciences at VCU includes the Rice Rivers Center, the Center for the Study of Biological Complexity and the Center for Environmental Studies.

“Those who knew Tom could not help but be swept up in his energy, intelligence and passion for the life sciences,” said VCU President Michael Rao, Ph.D. “From the labs on our campuses to the living laboratory of the Rice Rivers Center, Tom shepherded a new holistic way of looking at science.”

Interim Provost John Wiencek, Ph.D., said, “The VCU community has lost a talented and devoted leader, scientist, educator and friend. Although his absence will be difficult, his legacy will remain strong in the many world-class programs he took to prominence.”

As the inaugural vice provost for VCU Life Sciences, Huff was critical in the success of the academic programs and research initiatives in the highly interdisciplinary fields. Through his commitment to the study of biological complexity, he led hundreds of faculty members across both campuses and at the three VCU-chartered centers.

“Dr. Tom Huff was a quintessential VCU faculty member and administrator,” said Eugene Trani, Ph.D., former president of VCU. “He will be deeply missed. His legacy, however, will endure. As the founding vice provost for VCU Life Sciences, VCU is a greater institution because of Tom's tremendous efforts.”

Leonard Smock, Ph.D., professor and director of the Rice Rivers Center, said, "Tom was VCU Life Sciences. His enthusiasm, energy, intellect, and, most of all, his far-reaching vision was the cornerstone of interdisciplinary research and education at VCU. Tom loved his extended VCU family, and all of us benefited greatly from his friendship and leadership."

In addition to his work at VCU, Huff was involved in numerous organizations in the Richmond community including serving on the board of directors at Lewis Ginter Botanical Garden. He was also an avid fisherman and enjoyed photography.

“For nearly 30 years at VCU, Tom was a great collaborator, colleague and friend,” Rao said. “Our condolences go to his entire family. We hope they find comfort in a VCU community who mourns with them and offers our support.”

Huff is survived by his wife, May Ligon Huff; his daughter, Elizabeth, and his son, Thomas. Funeral arrangements are pending.

Searching for Purples

January 29, 2015

VCU Rice Rivers Center collaborator: Center for Conservation Biology

Bryan Watts

It was one of those magical days when the winds are light, the water feels like silk under the boat and you can’t see where the Bay ends and the sky begins. You have the sensation of speeding into a featureless wall of blue. Like riding a sled through fog on an icy hill, you enter the sublime and all time begins to bend and then fades away into blueness. A simple delight that more than makes up for the many poor-weather days in the field.

Purple sandpipers are different. When other sandpiper species migrate to tropical latitudes, they stubbornly overwinter along the frigid waters of the North Atlantic. The bulk of the population moves south just beyond the arctic ice, with birds remaining along the coasts of Newfoundland, Greenland and Iceland. While other shorebirds forage on sandy beaches, mudflats and marshes, they cling to rocks, dodging and weaving through crevices to pluck mollusks and crustaceans from slimy surfaces, escaping just as the next wave surges over. In winter they inhabit the raw, rocky coastline, a rugged habitat where we would like to be if only for a brief visit.

In part because they breed in such remote locations and winter in situations beyond easy human reach, our information on population status is incomplete. Recent estimates of birds wintering along the Western Atlantic fall around 16,000 individuals but may be twice that number. A recent analysis of trends suggests that the North American population may be declining.

The rocky coastline preferred by the purple sandpiper extends south only to New York. This is the position where the fall line (rocky formation that separates the piedmont from the coastal plain) reaches the coast. South of this location, the coast is comprised of the sandy habitats characteristic of the southern Coastal Plain. In recent centuries, we have used rocks to build islands, jetties, groins and other structures, creating rocky habitats for purple sandpipers and extending their winter range south.

On January 20, two CCB crews were out on the water to visit the largest of these artificial rock habitats within the Chesapeake Bay. They are rocky islands created to support the entrance of tunnels under the Bay, including the Chesapeake Bay Bridge Tunnel, the Hampton Roads Bridge Tunnel, and the Monitor Merrimac Bridge Tunnel. Because the islands are mostly inaccessible from the bridges, we surveyed the intertidal perimeter for shorebirds by boat.

We know very little about the ecology and population dynamics of purple sandpipers wintering in the mid-Atlantic Coastal Plain. Numbers may vary year to year depending on conditions in the heart of their winter range to the north. We detected only 86 purple sandpipers along more than 7 kilometers of rocky shoreline. The survey provides an initial baseline that may be compared to future surveys to examine interannual variation. In addition to the purples, we also recorded 64 sanderlings, 38 ruddy turnstones, 21 least sandpipers and 1 western sandpiper feeding on the rocks.

ILS alumni panel 2014

January 16, 2015

On November 20, 36 current ILS students were invited by ILS Program Director, Dr. Bill Eggleston to the annual ILS alumni panel, which is intended to aid graduates in being successful upon completion of the program. Dr. Sarah Golding, Instructor and Director of Undergraduate Research in the Department of Biology, spoke about the Preparing Future Faculty Program.

ILS alumni spoke about several different career paths after completing the ILS program, including paths in both higher education and the public sector. They included: Dr. Colleen Higgins, Instructor, Department of Biology; Dr. Christopher Waggener, Lead Scientist with the VA Division of Consolidated Laboratory Services; Dr. Julie Zinnert, Research Scientist, Department of Biology; and Dr. Billy Budd, Group Leader at AIBiotech in Richmond.

The alumni answered a battery of questions from the students relating to their fields, as well as the educational paths they took while at VCU.

Evaluating the Supply Side of Bird Migration within a Fall Staging Site

January 13, 2015

VCU Rice Rivers Center collaborator: Center for Conservation Biology

By Mike Wilson and Bryan Watts

The lower Delmarva Peninsula is one of the most significant migration bottlenecks in eastern North America where large numbers of birds become concentrated within a relatively small land area. Migrants stopping on the lower Delmarva Peninsula are attempting to replenish their energy reserves by accessing food resources in often unfamiliar habitats. Previous research conducted by the CCB has documented the number of migrant birds using forested and shrub habitats on the lower Delmarva. This work has allowed us to project the amount of energy required to maintain a positive energy budget for the migrant community. A central management objective within this landscape is to provide an energy source for migrating birds (i.e., birds are provided with opportunity for a net energy gain) rather than an energy sink (i.e., the peninsula cannot meet energetic demands). Realizing this success requires an understanding of relative supply and demand.

Fall fruits are an important food resource for birds during autumn migration because of their relatively high availability and because they are packed with high energy lipids that can be utilized directly or stored as fat. A large number of migrant species rely on insects during the breeding season but shift to a diet of fruit during autumn migration. Frugivorous birds account for nearly 60% of the total energetic demand of migrating birds using the Peninsula. Most of these birds are short distant migrants that remain in North America throughout the annual cycle but also include many Neotropical migrants that are in route towards wintering areas located within the Caribbean or Central and South America. Providing and maintaining habitats with sufficient fruit resources to meet these species energetic demands would be a primary management land objective for the lower Delmarva Peninsula.

We began field work during the autumn of 2014 to assess fruit availability, fruit nutrient content, and fruit use by migrant birds in shrub and forested habitats. The project has been funded by the United States Fish and Wildlife Service and in collaboration with the Eastern Shore National Wildlife Refuge and Scott McWilliams at the University of Rhode Island. Shrub and forest habitats differ markedly in physical structure and possibly fruit availability. These habitats also represent significantly different management endpoints that can be controlled by management intensity. Conservation agencies are currently formalizing long-range plans to benefit migrant birds with either shrub or forest as the ultimate vegetation condition for habitat parcels. Research like this is critical to informing final conclusions. The results of this project are pending analysis but will provide the first look at how well the lower Delmarva is servicing the energy demands of migrant landbirds and will help plot a course for future management decisions.

Virginia Peregrine Falcon 2014 Update

January 13, 2015

VCU Rice Rivers Center collaborator: Center for Conservation Biology

By Libby Mojica

Virginia’s Peregrine Falcon population continued to thrive in 2014 with 27 known breeding pairs producing 44 chicks. Virginia’s falcon population is predominantly on the coastal plain with 24 breeding pairs on the coast including 10 peregrine towers, 1 ground nest, 8 bridges, 1 Coast Guard navigation tower, 2 fishing shacks, 1 power plant stack, and 1 high-rise building. The population in the western part of the state remains small with only 3 pairs nesting on rock cliffs. The stronghold of the Virginia population continues to nest on man-made structures requiring regular maintenance and management from The Center for Conservation Biology (CCB) and the project’s many conservation partners.

The Peregrine Falcon was extirpated as a breeding species in Virginia by the 1960s in part because of nesting failures related to DDT. Many decades of reintroduction efforts by CCB, Cornell University, Virginia Department of Game and Inland Fisheries (VDGIF), and the National Park Service, have brought the breeding population back to pre-DDT levels. The Peregrine Falcon is listed as a threatened species in Virginia and continues to struggle with low fledging survival from bridge nests and threats from new emerging contaminants.

In 2014, the Virginia Department of Transportation (VDOT) managed disturbance buffers for 5 occupied falcon nests and coordinated extraction of the chicks for hacking. This effort required close coordination with VDOT bridge, traffic, and environmental staff to pull off accessing the nests with minimal impact to vehicle and boat traffic. The CCB continues to lead a 15-year partnership with Shenandoah National Park, VDGIF, and VDOT to translocate falcon chicks from bridges to the mountains to increase survival rates. Shenandoah biologists and interns released 9 falcons at Hogback Mountain through the hacking program, furthering reintroduction of falcons back into the Virginia mountains.

We continued our band resighting program for adult falcons using a digital game camera mounted at the entrance of the nest box. Fourteen breeding adults were identified, including 4 from New Jersey and 1 from New York. One of our newest pairs at the Silver Beach Range Tower is a mix of origins, with the female from Sea Isle city, NJ (212 km away), and the male from Gull Marsh, VA (19 km away). Often we have to review hundreds of images from the game camera to read the alphanumerics on the bands, piecing together the identity of the bird one image at a time.

For the second year in a row, a pair of falcons nested on the ground on a sand dune on a barrier island. This is a rare occurrence and noteworthy for the species in our part of the species’ range. Unfortunately the pair was unsuccessful this year because of extreme heat and no shade protection for the nest and nestlings.

Project Partners: The Virginia Department of Game and Inland Fisheries, National Aeronautics and Space Administration, National Park Service, United States Fish and Wildlife Service, Virginia Department of Transportation, The Nature Conservancy, Dominion Power, and United States Coast Guard.

Virginia red-cockaded woodpeckers continue to surpass expectations

January 12, 2015

This past year of 2014 was one of the most memorable and successful conservation leaps for the Virginia Red-cockaded Woodpecker population in recent history. The Center for Conservation Biology has just completed the year-round monitoring of the state’s only population of the woodpecker at the Nature Conservancy’s Piney Grove Preserve. Surveys resulted in new milestones for number of breeding pairs and overall bird numbers.

It was just two years ago that we shared the report that the population had reached a modern-day high of ten breeding pairs. This was the original conservation goal when the Piney Grove Preserve was established in 2001. However, in 2014 that number was smashed with the addition of four new breeding pairs on the Preserve. The new pairs were mostly established by dispersal of woodpeckers into new breeding areas, including the first documented incidence of a male pioneering a new territory by excavating a cavity within a lone tree away from other existing groups of birds. The formation of new territories in past years has always been facilitated by the installation of artificial cavities. Another first-time event occurred when a breeding pair was established by rare intra-cluster budding, which is the term used when two pairs of adults breed within the same group without establishing a new territory.

Center biologists just completed the winter population survey and detected 67 birds within 14 groups. Red-cockaded Woodpeckers are cooperative breeders, with each group consisting of the breeding male and female and often additional nest helpers that remain together throughout the year and often forage and work together during the day. The 2014 count exceeded the previous high of 57 birds set in 2013 and more than doubles the low count of 21 birds from 2001.

The success of Red-cockaded Woodpecker management within the Piney Grove Preserve is one of the greatest conservation achievements in Virginia and a highpoint for restoration of the species throughout its broader range. This endangered bird reached an all-time low of two breeding pairs when the Nature Conservancy purchased the land and initiated restoration efforts. The Preserve has undergone a remarkable transformation in physical character over the years through timber management and prescribed burning guided by the Nature Conservancy. These efforts have been critical to the continued recovery of the population.

Unwelcome neighbors

January 12, 2015

By Bryan Watts

On March 22, 1936, Bryant Tyrrell traveled to the farm of Hiram Brown near Chestertown, Maryland, to investigate a report of a bald eagle nest. Upon entering the colonial-era manor house built in 1708, he was shown into the sitting room and led to the large wooden mantel over the fireplace. There he was proudly shown four sets of marks that had been etched into the wood. The marks spanned 7 feet 1 ¼ inches, 6 feet 11 ¾ inches, 6 feet 10 ¼ inches, and 6 feet 9 ¾ inches. Mr. Brown explained that these marks recorded the wingspans of four eagles that had been shot on the property, trophies of past family adventures.

Just nine days later on March 31, Tyrrell was taken to a nest constructed in a dead American chestnut on Eagle Point along the Bush River. The nest was on Edgewood Arsenal, a government facility established to produce mustard gas following the entry of the United States into World War I. Although a single adult eagle was seen in the territory, the nest had not been used since an adult was shot there two years previous. On this same day, Tyrrell was led to a second nest on the arsenal. The nest was built in a large oak on Robbins Point and was also abandoned. He was to discover later in December that three young birds were killed there by hunters who believed the birds were feeding on ducks. Examination of their stomachs revealed only fish.

On April 14, John Shelton led Tyrrell down a long foot path to High Point. High Point is a bluff overlooking Belmont Bay where Occoquan Creek enters the Potomac River east of Washington, D.C. The commanding view over a large expanse of water and abundant prey attracted eagles like a magnet. On this day, Shelton would take Tyrrell to a tremendous American chestnut tree that had recently died from chestnut blight. The tree towered over the surroundings and was the primary eagle perch on the bluff where birds came and went throughout the day. Shelton indicated that he knew of more than 50 eagles that had been shot from the tree, and during their visit the two men found a fresh carcass on the ground. Thirty years later, this site would become Mason Neck National Wildlife Refuge.

On May 7, George Frederick took Tyrrell to a nest on Upper Chippokes Creek near Claremont on the James River. Mr. Frederick, who ran a line of several hundred muskrat traps along the upper James, had previously killed one young in the nest but the second remained. He explained that the attitude toward eagles in this part of the Bay was very poor. Eagles regularly discovered muskrats in his traps and would make a meal of them, damaging the pelts. He estimated that he lost 10 muskrats weekly to eagles, amounting in a total loss of more than 10 dollars per week. When partially-eaten muskrats were found, the local practice was to set several additional traps around the kill so that when the eagles returned they would be caught and later shot.

On June 9, Howard Green took Tyrrell to a nest on Ordinary Point Farm along the Sassafras River. Mr. Green was surprised to see two large young in the nest and said he would return the next day with a rifle to kill them. On this same day, Tyrrell met Roy Mitchell who owned a farm on Freeman Creek along the Sassafras. Mr. Mitchell indicated that earlier in the season he had seen an adult eagle catching his chickens and so had killed the young in the suspected nest on his property.

During the spring of 1936, W. Bryant Tyrrell by foot and car conducted the first survey of bald eagles throughout the Chesapeake Bay. His field log records the best assessment we have of the general number of eagle pairs and their productivity prior to the DDT era. His interactions with landowners also record the sentiment of people toward eagles during this time period around the Great Depression. Watermen, duck hunters, fur trappers, farmers and lumbermen all seemed to have their own concerns and attitudes about the presence of eagles in the Bay. Although the time was nearly twenty years after the passage of the Migratory Bird Treaty Act and killing eagles was a violation of federal law, the practice was accepted by the culture of the day. More than accepted, within this resource-based economy during a time of great hardship, there was an unmistakable kinship that eclipsed the value of the eagle population.

Although we continue to have the occasional boy attempting to “test his sense of manhood” by shooting an eagle, the days of widespread killing have drifted beyond our cultural memory into the gray past. Today, the bald eagle breeding population is booming within the Chesapeake Bay and is approaching numbers likely not seen since colonial times. Many people living in the Chesapeake watershed now live in upscale residential developments named “Eagles Landing”, “Eagle Shores” or “Eagle Bluff”, a clear indication that attitudes toward our national symbol have shifted over the past 80 years. Both the eagles and people of the Chesapeake Bay survived the Great Depression. The continuing hope is that our two populations, now completely intertwined, will have a lasting future together.

Tracking a shorebird to the ends of the earth

December 17, 2014

By Fletcher Smith

The journey begins in darkness in Virginia with an early morning flight departing from the Norfolk International Airport in late May. The air is humid, and the days have been hot along the mid-Atlantic Coast. The first leg of the trip is to Toronto, Canada. Subsequent flights take me through the Prairie Provinces (with an overnight stay), and finally on to Yellowknife, Canada. Yellowknife, the capital of the Northwest Territories, is where much of the logistical planning for the field season ahead takes place. The main focus of this collaboration between the Canadian Wildlife Service and The Center for Conservation Biology is the satellite tracking of whimbrels throughout their life cycle. The important task of rigging the satellite transmitters for deployment in the field takes place here in Yellowknife. The transmitters are placed in the carry-on luggage as they are irreplaceable if lost. The trip to Yellowknife has taken two days and nearly 3,000 miles are behind me at this point.

After a few days of last minute preparations, the team of biologists, technicians, and student interns leaves via airplane for the small town of Inuvik, located along a main branch of the Mackenzie River. This leg of the journey adds another 650 miles to the total, which is now at 3,650 miles and 4 days of travel time. Inuvik is where the final logistical steps take place; securing helicopter and Twin Otter flights into the bush, purchasing most of the food we will eat for the next 6 weeks, loading up gear at the airplane hangar, filling up gasoline and propane containers, and packing other crucial supplies that will be used in the coming field season. The total weight of the gear approaches two tons, and some of it is redundant, but there will be no option to stop at the local convenience store to pick up necessary supplies after we are dropped in camp.

The next leg of the journey begins on the first good weather day (which can be few and far between this time of year), and the team splits into two groups, one going with the helicopter and one with the plane. The helicopter flight from Inuvik to the outer Mackenzie Delta is an eye opener. During this flight, the team will cross hundreds of miles of frozen rivers, lakes, and snow-covered ground. With daily average low temperatures at around minus 20 Fahrenheit between mid-November and early April, ice breakup in the delta can take a while. This intensely long, cold, dark winter is one reason that few people inhabit the northern Arctic region. The spring and summer are best characterized by light. The sun never sets during the field season, and the ice and snow quickly thaw in the midnight sun. The average temperatures during the field season are between 40 and 60 Fahrenheit, relatively balmy compared to the deep cold of winter.

One team helps to unload the plane at a remote landing strip appropriately named Camp Farewell. The other team flies via helicopter to the gravel pad that will be home for the next six weeks. The process takes a full day, with the helicopter bringing in loads of gear hanging from a sling from Farewell to the field campsite. After the gear is dropped, the team puts together the equipment that will be used throughout the field season to collect data on nesting shorebirds. All supplies are distributed, including GPS units, pens, pencils, field notebooks, cameras, and banding equipment. The main kitchen area is set up in an igloo-like structure that allows respite from the biting insects. The storage tent is erected and all the food (calculated to be five pounds of food for each person each day!) is placed inside. The sleeping tents are placed on the far end of the pad, and a bear fence is erected around them. The possibility of having a bear come into camp to investigate the food tent or gasoline cans is very real, so those items are kept as far away from our sleeping tents as possible. We have put another 120 miles behind us, and can go no further north without swimming in the Beaufort Sea. The journey has taken about a week so far, and nearly 4,000 total miles are behind me.

The whimbrel’s migration to breeding grounds started just before my departure from Norfolk on that late May morning. The birds originated from wintering grounds in Brazil, where they spent seven months in the Gulf of Maranhão region. There they fattened up for the journey north. Whimbrels complete the almost 4,000 mile journey to North American staging grounds in about five days. They arrive exhausted, and must build up fat immediately. The two stopover sites for the Mackenzie Delta breeding population are quite different. Along the Atlantic Coast, the vast coastal marshes of Virginia, South Carolina, and Georgia host the greater part of the Atlantic migrant population, where they feast on the seemingly endless supply of fiddler crabs. The Gulf Coast migrants stage between Mexico and Louisiana, using habitat ranging from crawfish farms and rice impoundments to natural coastal marshes for foraging and roosting. The Gulf Coast birds have a more varied palate, with fiddler crabs, crawfish, and marine invertebrates making up the majority of the diet at this stopover site. The birds will stay at these sites for close to a month, building up fat reserves and preparing for the next leg of their journey.

Migration begins when the pangs of Zugenruhe become too much to suppress. The birds leave the Atlantic Coast staging areas during a relatively short window; more than 90% of the birds leave within a five-day period in the latter part of May. Many thousands are observed annually during this time in coastal Virginia. During the 2014 season, a new record of 8,192 individual whimbrels was counted, and nearly 6,000 of that total were observed between the 24th through 26th of May alone. The birds fly from the Atlantic Coast to the breeding grounds, covering the 4,000 miles to the Mackenzie Delta in a five-day, non-stop flight, quicker than it takes a biologist to cover the same distance (although biologists stop along the way to eat, sleep, and drink). The Gulf Coast whimbrels utilize a different migration strategy. They depart the Gulf Coast habitats in early May, stopping for short periods along the Platte River in Nebraska and in the irrigated farmlands of southern Alberta and Saskatchewan. The final 1,500 mile flights to the breeding grounds take place in the third week of May.

Once the whimbrels (and other shorebirds) and biologists converge on the same marsh-dominated breeding grounds of the outer Mackenzie River Delta, the real work begins. As part of the Arctic Shorebird Demographic Network (ASDN) and the Program for Regional and International Shorebird Monitoring (PRISM) programs, the Mackenzie Delta camp monitors the breeding success, population densities, annual survival, and other important parameters that are necessary in answering questions regarding population declines of shorebirds breeding in the Arctic regions.

After locating a nest, a walk-in trap is placed over the nest and the whimbrel is trapped within minutes upon returning to incubate. The bird is held by one of the researchers while the harness for the satellite transmitter is custom fitted. After she is released and continues to incubate her eggs, the nest is monitored until the eggs hatch or fail; nest failure is usually caused by predation by arctic fox, raven, or jaeger. In both 2012 and 2013, nest success rate was near zero for whimbrels, but in 2014 it was a boom year. Over 50 percent of the nests hatched and many chicks were observed in the marshes. One possible explanation for the uptick is that there may have been a good number of lemmings in the nesting area in 2014. Although lemmings are tough to see in the marshy habitat, two were observed being captured in the Delta by a single parasitic jaeger, each within minutes of one another, suggesting that an abundance of prey allowed the whimbrels relief from the attention of the predators that had been feeding on shorebird eggs the previous two seasons.

After the nest monitoring and trapping of shorebirds is finished, we begin process of breaking camp, while excess food or gas is given to local people passing by on their way to hunting camps along the outer coast. Data is squared away and equipment carefully packed. With luck, the departure date will have good weather to avoid any delays home. The distant thumping of the rotors of a helicopter signal that our long journey back home has begun, and our hearts are glad with the anticipation of taking a hot shower and soon seeing loved ones.

Shortly after we leave field camp, the whimbrels will depart the Mackenzie Delta en route to their winter destination in Brazil to complete the loop on their astounding 14,000 mile annual migration. The tracking project has brought to light whimbrel behavior that challenges previously held beliefs about the migration routes of these birds. The overlap between the Mackenzie Delta population and the Hudson Bay population on the wintering grounds and Atlantic Coast staging areas was completely unknown prior to this study. Several critically important staging areas have been discovered because of this tracking project. The Center for Conservation Biology continues to lead whimbrel conservation research and plans are underway to work with these magnificent fliers in 2015.

 

VCU Rice Rivers Center receives award

The Center for Conservation Biology at VCU Rice Center tracks flight of ‘Hope’

August 19, 2009

Hope, a whimbrel carrying a satellite transmitter, made landfall Friday evening on St. Croix after completing an extraordinary 100 hour, 5,720 kilometer (3,500 mile) flight over the open ocean toward her wintering grounds in South America.
The bird had been staging on Southampton Island in the northern reach of Hudson Bay since July 15 before leaving on a non-stop flight south on Aug. 10. The bird flew south over Hudson Bay, crossed the interior of Canada and New England to emerge from the coast of Maine and out over the open ocean.
Flying more than 1,600 kilometers (1,000 miles) over the ocean and east of Bermuda, Hope then turned south and moved toward the Caribbean. Before landing in St. Croix, Hope had been on the wing for six days with an average flight speed of 60 kilometers/hour (37 miles/hour).

Hope was originally captured and fitted with a satellite transmitter on May 19, while staging on the Delmarva Peninsula of Virginia. She left Virginia on May 26 and flew to the western shore of James Bay in Canada. She staged on James Bay for three weeks before flying to the MacKenzie River near Alaska and then on to the Beaufort Sea where she staged for more than two weeks before flying back to Hudson Bay. Hope has traveled more than 21,000 kilometers (13,000 miles) since late May. 

Hope is one of several birds that has been fitted with a state-of-the-art 9.5 gram, satellite transmitters in a collaborative effort by the Center for Conservation Biology at the College of William and Mary - Virginia Commonwealth University and the Virginia Chapter of the Nature Conservancy to discover migratory routes that connect breeding and winter areas, and to identify en route staging areas that are critical to the conservation of this declining species.

Background

The whimbrel is a large, holarctic, highly migratory shorebird. The North American race includes two disjunct breeding populations both of which winter primarily in Central and South America. The western population breeds in Alaska and the Northwest Territories of Canada. The eastern population breeds south and west of Hudson Bay in Manitoba and Ontario. Both populations are of high conservation concern due to dramatic declines in recent decades.

Satellite tracking represents only one aspect of a broader, integrated investigation of whimbrel migration. During the past two years, the CCB in partnership with The Nature Conservancy and the U.S. Fish and Wildlife Service has used conventional transmitters to examine stopover duration, conducted aerial surveys to estimate seasonal numbers, collected feather samples to locate summer and winter areas through stable-isotope analysis, and has initiated a whimbrel watch program. Continued research is planned to further link populations across staging, breeding and wintering areas, and to determine the ecological requirements of whimbrels staging along the peninsula.

A night of blacklights and owls at the Rice Center

July 7, 2009

By Arthur V. Evans

The 342 acres of riparian woodlands and wetlands hugging the upper shore of the James River at the VCU Rice Center in Charles City County is the perfect place to stage events that blend science and scientists with students, educators, and naturalists.

One such event was “A Night of Blacklights and Owls,” held on June 27-28 organized by Anne Wright, Life Science Outreach Education coordinator. The evening was designed as an “advanced field experience and training” for the Riverine and Pocahontas Chapters of the Virginia Master Naturalist program and included members of the Powhatan/Dutch Gap MAPS (Monitoring Avian Productivity and Survivorship) Program. Forty-five people took part in the evening’s festivities, which ran from Saturday at 7 p.m. to Sunday at 9 a.m.

Entomologist and VCU Life Sciences Research Associate Dr. Art Evans established seven black light stations to attract night-flying insects to share with the group. The insects collected during the evening were part of an effort to document the fauna at Rice and establish a permanent reference and teaching collection for the center.

The highlight of the evening was finding a rarely encountered turtle beetle, Chelonarium lecontei (Photo 2), the fourth known to be collected in Virginia. The turtle beetle is the sole North American species of the mostly tropical family Chelonariidae. It ranges from Virginia to Florida, west to Oklahoma and Texas. Nothing is known of its larval stages, but it is suspected that they occur in rotten wood, possibly in association with ants. Adults are attracted to lights during the months of June and July, or are found resting on vegetation, especially at night.

Master Bander and VCU Professor of Economics Dr. Robert Reilly led regular owling forays into the woods, broadcasting the recorded calls of both owls and distressed rodents to lure owls down from their lofty perches so folks could get a better look. VCU’s Holly Houtz, Life Sciences’ Lab and Outreach Education Specialist, and Mary Arginteanu and Julie Kacmarcik of MAPS assisted Reilly in his efforts.

The owls were less than cooperative but for those intrepid naturalists still up and about around 2 a.m. they were treated to some fine barred owl action.

Judging by the excitement and positive comments generated by all who attended the program along the James River, it appears that there is demand in Central Virginia for outdoor science events such as “Black lights and Owls.” Future programs are being developed at the VCU Rice Center for both the Master Naturalists and the general public to participate in.

Christmas Bird Count

January 11, 2008

Several VCU Rice Center staff and student volunteers participated in the 108th Audubon Christmas Bird Count in December 2007. The primary objective of the Christmas Bird Count is to monitor the status and distribution of bird populations across the western hemisphere during the early winter.

More than 2,000 individual counts took place throughout the Americas and beyond from Dec. 14, 2007 to Jan. 5, 2008. The VCU team participated in the Hopewell Count on Dec. 16. The team broke into two groups. One group conducted an all day count at the Rice Center while the other group joined Cyrus Brame, USFWS, to survey Presquile National Wildlife Preserve, just upstream of the Rice Center.

The following is an excerpt from a report from Hopewell Count Coordinator Arun Bose.

“Despite challenging weather conditions, with rain at the beginning of the day and high winds toward the end, once again the Hopewell CBC reached a new high count for species recorded on count day –115. Two additional species were recorded during count week; Greater White-fronted Goose (2) and Lesser Black-backed Gull (1). A total of 53,421 individual birds were counted which is up from last year’s count of 33,843.”

Also two new species were added to the count – Willet and White-eyed Vireo. Both species were documented with written descriptions. The Willet was at the VCU Rice Center and the White-eyed Vireo at Westover Plantation; both in Charles City County.

Willet is described in Virginia’s Birdlife an Annotated Checklist as “... rare west of the Chesapeake Bay and the salt marshes along the lower reaches of the Bay’s tributaries ...” There is a single prior winter record of Willet in King William County on Jan. 31, 2004.

Other highlights of the day included 24 Red-headed Woodpeckers, 15 from the VCU Rice Center.

Kudo’s to Dr. Len Smock, Rice Center director, for observing and documenting the Willet!

HHMI grants connect research institutions with local schools

June 21, 2007

On June 21, the Howard Hughes Medical Institute formally announced that VCU was the recipient of a $750,000 grant to implement programs targeting teachers, community members and students highlighting applied systems biology. Some of these programs will involve hands-on workshops at the VCU Rice Center. Dr Richard Rezba, Director of the Center for Life Sciences Education is PI on this grant, which was one of only 32 awarded out of 297 applications.

Virginia is for science lovers

As researchers generate vast quantities of data about individual genes, proteins and signaling pathways, scientists are realizing that true understanding of complex biological systems requires studying how these components work together. By focusing on the cell or organism as a whole, rather than merely the sum of its parts, systems biologists hope to open new avenues to understanding, preventing and treating disease. To help train future scientists to think like systems biologists, VCU in Richmond is taking a similarly integrated approach. It will use its $750,000 grant from HHMI to implement programs targeting teachers, community members and students at many educational levels. Graduate students and postdoctoral fellows will introduce kindergarten through 12th grade science teachers to research techniques in workshops highlighting applied systems biology. This training will help teachers create activities that encourage students to design and conduct their own scientific inquiries. The HHMI grant will also support development of a systems biology component to VCU’s popular “Secrets of the Sequence” public education campaign, through which educators can download videos and accompanying lesson plans and activities.

Varina High School students examine salamanders at VCU Rice Center

March 13, 2007

Students from Varina High School’s AP Environmental class made their third visit to the VCU Rice Center this year. On March 2 students helped monitor the spotted salamander migration in the vernal pools. Under the direction of graduate student Leeanna Pletcher, they weighed, measured and photographically documented over 80 salamanders. They also took water chemistry measurements from the pools. This is the second salamander project the students have participated in. Their teacher, Jeff Meador, will have his students analyze the data for inclusion in the VCU Rice Center database.

 

 

VCU Rice Center recently announced the addition of a Conservation Medicine Program

February 20, 2007

At the Jan. 24 meeting of the VCU Rice Center Board of Trustees, a new Conservation Medicine Program was announced to unite the study of human, animal and environmental health at the VCU Rice Center.

Dr. Joy Ware was appointed as the first Director of the Conservation Medicine Program. Dr. Ware is a Professor in the Department of Pathology in the VCU School of Medicine and in addition to being a nationally recognized cancer researcher. She is also active in the investigation of wildlife diseases. She is a member of the Wildlife Diseases Association and the Association of Reptilian and Amphibian Veterinarians. Dr. Ware has already brought together a strong team of researchers from both the academic and medical campuses to focus on amphibian and reptile health and disease. Following an initial finding of a new type of fungal infection in both spotted and marbled salamanders at the VCU Rice Center, Dr. Ware and several collaborators around the state are investigating the distribution and significance of this disease for amphibians of Virginia.

Monitoring the population dynamics, migration, and health status of salamander species inhabiting the VCU Rice Center and area refuges not only will provide important insights into the baseline health of amphibians but will also facilitate development of conservation strategies worldwide. These salamanders are excellent environmental monitors of local and regional conditions. Disease development often accompanies immune suppression due to climate change, chemical contaminants and pesticides. Thus, these animals may act as indicators of environmental changes that could one day affect human health. It is unfortunate that there are observed declines in amphibian populations worldwide since it has already been found that increased biodiversity reduces the incidence of Lyme Disease in people and some investigators have shown that when tick nymphs attach to some species of lizards, the blood of the lizard actually kills the bacteria that cause Lyme Disease. Dr. Ware has therefore determined that in conjunction with the study on salamanders, a portion of the conservation medicine research will be focused on the further investigation of the possibility that Eastern Fence lizard blood can kill the agent that causes Lyme Disease.

High school students help develop a terrestrial salamander monitoring program at the VCU Rice Center

February 9, 2007

On Jan. 26, Anne Wright, Coordinator of the Life Sciences Outreach Educational Program, took the AP Environmental class from Varina High School on their second field trip of the year to the VCU Rice Center. The students prepared and placed a transect of salamander boards through a section of hardwood forest on the western edge of the property. This was the first of several transects to be placed at Rice to develop a terrestrial salamander monitoring program. Salamanders are an important component of the forest ecosystem yet little is known about their population dynamics. The monitoring program will help to determine what species of terrestrial salamanders are present, the size and health of their populations and potential changes in their numbers over time. The students also did a "clean up" and removed over 30 tires, two oil drums, a car door, a mail box and 10 bags of bottles and trash from the forest. Graduate student Leeanna Pletcher and service learning students Ricky Davis and Rachel Hardey assisted with the activities.

Researchers receive $210,000 grant from the National Science Foundation

January 24, 2007

VCU Rice Center Researcher Dr. Rodney Dyer, along with his co-PI Dr. David Chan from the Department of Mathematics and Applied Mathematics, have recently been awarded a $210,000 grant from the National Science Foundation for their work on pollen dispersal. This is an especially exciting grant for the VCU Rice Center since all the research is being conducted on site. The title of the grant is "Unifying the Two-Generation Analysis to Pollen Movement: Analysis of Insect Mediated Pollen Dispersal in the Understory Tree Cornus florida L."

Abstract

The movement of genes from one generation to the next is the critical process that maintains the genetic connectivity of populations. For most plant species, pollen is the most pervasive vector of gene exchange and is typically transmitted by either wind or via a dispersal vector such as insects or animals. As empirical data on landscape-level gene movement continues to accumulate, it is becoming apparent that insect mediated dispersal produces significantly different spatial distribution patterns of genetic structure than species that use wind as their primary dispersal mechanism. This project is focused on the examination of insect-mediated dispersal using the understory tree, Cornus florida (L; flowering dogwood). We will be using both mathematical models and genetic analyses of natural populations to understand the spatial patterning of insect-mediated pollination and investigate the ecological factors that may influence this process.

Combining mathematical models that are sensitive to the mode of dispersal with genetic data that can identify the spatial movement of genes provides unique insights into this most critical process. Moreover, placing these analyses within an ecological context allows us to understand how the environment influences the behavior of insects that move plant genes across the landscape. The results of this research will ultimately allow us to design more effective management and conservation strategies for natural populations.

Local high school students study macroinvertebrate sampling at VCU Rice Center

December 1, 2006

On Friday, Dec. 1, the Advanced Placement Environmental class at Varina High School visited the VCU Rice Center to learn about macroinvertebrate sampling. Anne Wright, the coordinator of VCU Life Sciences Outreach Education programs, led 21 students and their teacher through several exercises. The class sampled Herring Creek as well as Kimages Creek at the northern end of Lake Charles where water had receded due to the breach of the dam. The students learned the importance of vernal pools and studied the animals that use them.

The gift, which will be funded over two years, allows for the development of two new weeklong, summer residential teacher training workshops in 2007 and two more in 2008. The workshops will focus on wetlands restoration with an emphasis on sustainable waters.

VCU chapter of the American Chemical Society Student Affiliates works at the Rice Center

November 11, 2006

On Saturday, Nov. 11, the VCU chapter of the American Chemical Society Student Affiliates took soil and water samples from a variety of locations at the VCU Rice Center. The samples will be tested for heavy metal content and the results will provide a baseline for a variety of metals such as mercury, arsenic and lead. The work is part of a new and exciting collaboration between the VCU Department of Chemistry and VCU Life Sciences that has great potential to give even more students hands-on experience in environmental monitoring and laboratory methods, adding to VCU Rice Center’s role as a “living laboratory.

 

Audubon celebrates the Lower James River Important Bird Area

October 21, 2006

On Saturday, Oct. 21, at a ceremony at the Presquile National Wildlife Refuge, the Virginia Commonwealth University Rice Center was recognized and awarded a plaque distinguishing the center as an important entity within the newly designated "Lower James River Important Bird Area." The Lower James is part of a global network of places recognized for their Outstanding Value to Bird Conservation and this particular designation culminates many years of dedication by hundreds of concerned citizens to preserve the legacy and beauty of this area of Virginia. Two scientists were specifically recognized for their scientific contributions and leadership in this area effort. One was Dr. Mitchell Byrd, from the Center for Conservation Biology at the College of William and Mary, centering on his work with eagles and the other was Dr. Charles Blem from VCU, whose long-term work on the migratory patterns and breeding habits of the Prothonotary Warbler is a major on-going research focus for the VCU Rice Center.

Symposium on the State of the James River

October 19, 2006

More than 70 participants attended the Symposium on the State of the James River held at Virginia Commonwealth University on Oct. 19. The purpose of the Symposium was to bring together individuals, agencies and institutions involved in research, monitoring and advocacy issues concerning the James River. The Symposium was organized by Dr. Paul Bukaveckas (Department of Biology and Center for Environmental Studies) in cooperation with the Virginia Department of Environmental Quality and the James River Association. Funding was provided by a National Science Foundation grant in support of VCU’s Rice Center for Environmental Life Sciences.

Opening remarks by Virginia's Secretary for Natural Resources, The Honorable L. Preston Bryant Jr., stressed the need for cooperation among state agencies, universities and citizen groups to maximize the effectiveness of river management efforts. Morning presentations described land use changes in the James River basin and their effects on water quality. The afternoon session was introduced by Rebecca Wodder (American Rivers) and focused on the living resources of the river, with speakers describing the current state of macroinvertebrate, fish and bird communities. David Bolgrien, the keynote speaker from the USEPA, described the agency’s efforts to develop indicators of ecosystem health for large rivers in preparation for the first national assessment of river condition. As a follow-up to the Symposium, the James River Association will prepare a State of the James report.

Influence of Substrate Quality and Moisture Availability on Microbial Communities and Litter Decompo

November 11, 2014

The VCU Rice Rivers Center congratulates Drs. David J. Berrier, Morgan S. Rawls, Shannon Leigh McCallister and Rima B. Franklin on their publication: “Influence of Substrate Quality and Moisture Availability on Microbial Communities and Litter Decomposition”, published in the Open Journal of Ecology.

The abstract reads as follows:

The main source of carbon (C) to soil stocks is plant litter, the decomposition of which is controlled by a mixture of physical, chemical, and biological processes. Bacteria and fungi are the dominant biota responsible for decomposition, yet we know very little about their respective contributions or how community dynamics may be affected by litter quality. This study sought to gain a better understanding of the variable relationships between organic matter decomposition, litter quality, and microbial community composition, with a specific focus on distinguishing bacterial and fungal dynamics. Experiments were conducted under contrasting hydrological conditions, comparing a wetland with an upland forest environment. Decomposition of native vegetation was monitored in addition to breakdown of a common substrate (Acer rubrum (red maple) leaves) placed in both environments. In situ incubations lasted 16 months, and were sampled at ~3-month intervals. Regardless of site, maple litter decomposition proceeded at a similar rate, though we did observe differences in litter quality over time (C:N, %N, solubility of organic C). For the upland site, native litter decomposed more slowly than the maple did. At the wetland site, both litter types decomposed at a similar rate which, surprisingly, was faster than either litter type at the upland site. This finding could be attributed to water-limitation at the upland site and/or stimulation of decomposition at the wetland site due to allochthonous nutrient inputs or organic matter priming. Substrate induced respiration (SIR) was measured for native litter incubated at each sampling site, and the relative contributions of bacteria and fungi were compared. No consistent major differences were detected across these microbial groups, though we did observe much higher rates of SIR at the wetland site compared to the upland site. Community structure of each microbial group was examined via terminal restriction fragment length polymorphism (TRFLP), which revealed dramatic temporal shifts for both groups at both sites. In general, these results indicate a long-term effect of both litter type and environmental conditions (site) on the bacterial community, but show only environmental effects on the fungal communities. This suggests that different environmental conditions allow microbial communities to uniquely approach decomposition of leaf litter components.

Exposure to the Cyanotoxin Microcystin Arising from Interspecific Differences in Feeding Habits amon

November 11, 2014

The VCU Rice Rivers Center congratulates Drs. Joseph D. Wood, Rima B. Franklin, Greg Garman, Stephen McIninch and Paul A. Bukaveckas, and Aaron J. Porter on their publication: “Exposure to the Cyanotoxin Microcystin Arising from Interspecific Differences in Feeding Habits among Fish and Shellfish in the James River Estuary, Virginia”, published in Environmental Science and Technology.

The abstract reads as follows: The cyanotoxin, microcystin (MC), is known to accumulate in the tissues of diverse aquatic biota although factors influencing exposure, such as feeding habits and seasonal patterns in toxin production, are poorly known. We analyzed seasonal variation in the MC content of primary and secondary consumers, and used dietary analysis (gut contents and stable isotopes) to improve understanding of cyanotoxin transport in food webs. Periods of elevated toxin concentration were associated with peaks in the abundance of genes specific to Microcystis and MC toxin production (mcyD). Peak toxin levels in consumer tissues coincided with peak MC concentrations in seston. However, toxins in tissues persisted in overwintering populations suggesting that potential health impacts may not be limited to bloom periods. Interspecific differences in tissue MC concentrations were related to feeding habits and organic matter sources as pelagic fishes ingested a greater proportion of algae in their diet, which resulted in greater MC content in liver and muscle tissues. Sediments contained a greater proportion of allochthonous (terrestrial) organic matter and lower concentrations of MC, resulting in lower toxin concentrations among benthic detritivores. Among shellfish, the benthic suspension feeder Rangia cuneata (wedge clam) showed seasonal avoidance of toxin ingestion due to low feeding rates during periods of elevated MC. Among predators, adult Blue Catfish had low MC concentrations, whereas Blue Crabs exhibited high levels of MC in both muscle and viscera.

Migratory Movements of American Shad in the James River Fall Zone, Virginia

November 11, 2014

The VCU Rice Rivers Center congratulates Drs. Aaron W. Aunins, Bonnie L. Brown, Matt Balazik and Greg C. Garman on their publication: “Migratory Movements of American Shad in the James River Fall Zone, Virginia”, published in the North American Journal of Fisheries Management.

The abstract reads as follows: The installation of Bosher’s Dam fishway and notches or breaches to all dams downstream in the James River, Virginia, were completed during 1989-19999 to help restore the river’s alosine populations by providing access to over 400 river kilometers (rkm) of historical spawning habitat that had been blocked for about 175 years. We used stationary radiotelemetry receivers in April-July 2009 to assess the passage of tagged adult American Shad Alosa sapidissima through the fall zone and Bosher’s Dam fishway. Three receivers encompassed 25 rkm from below head of tide to 3 rkm above Bosher’s Dam. Ninety-four American Shad were radio-tagged over 30 d, either at the head of tide (n=64) or upstream below the Bosher’s Dam fishway (n=30). No American Shad tagged at the head of tide were detected at the base of Bosher’s Dam, and none were detected above Bosher’s Dam fishway. However, several tagged fish released at the base of Bosher’s Dam remained there for days (x=4.0 d, DS = 5.9 d) without negotiating the fishway. These results suggest that passage at Bosher’s Dam and through other fall zone dams needs improvement and that American Shad access to historical spawning habitat remains thwarted.

eESP 2.0 update

November 11, 2014

On Wednesday Oct. 1, Daniel McGarvey (Center for Environmental Studies) and Laura Chessin (Graphic Design) assembled seniors from the Environmental Studies and Graphic Design programs at the new Depot (Arts) facility to begin a series of collaborative Capstone projects. Through the remainder of the semester, students from the two programs will work together to develop solutions to local environmental problems/challenges (e.g., reduction of storm water runoff, proliferation of non-native pest species, and on-campus composting facilities), and to create communication products that can be used in community outreach and engagement efforts.

 

 

 

 

eESP 2.0 students review initial projects submitted by their classmates

In the process, Environmental Studies students will have a unique opportunity to apply what they have already learned and to gain insight to the design and communication process. Graphic Design students will, in turn, acquire in-depth knowledge of select environmental topics while building their professional portfolios. This process will build upon the initial Capstone collaboration, conducted last fall, but will raise the bar on expectations for project outcomes. For instance, students will be required to contact potential community partners and to prepare materials for posting on the Science Matters (NPR/Community Idea Stations) website.

Nitrogen Retention in a Restored Tidal Stream (Kimages Creek, VA) Assessed by Mass Balance and Trace

November 12, 2014

The VCU Rice Rivers Center congratulates Drs. Paul A. Bukaveckas and Joseph Wood on their publication: ”Nitrogen Retention in a Restored Tidal Stream (Kimages Creek, VA) Assessed by Mass Balance and Tracer Approaches”, published in the Journal of Environmental Quality.

The abstract reads as follows:

Tidal streams are attractive candidates for restoration because of their capacity to retain nutrients from upland and estuarine sources. We quantified N retention in Kimages Creek, VA, following a dam breach that restored its historical (pre-1920) connection to the James River Estuary. Estimates of N retention derived from mass balance analysis were compared to tracer-based retention estimates obtained by injecting NH4Cl during an incoming tide and measuring recovery on the outgoing tide. The injection experiments showed that dissolved inorganic N (DIN) retention in the restored tidal and nontidal segments was similar to nearby streams and previously published values. These data suggest that the stream has attained expected levels of functioning less than 2 yr after restoration despite 80 yr of impoundment. The mass balance analysis provided additional information for restoration assessment as this approach allowed us to track multiple N fractions. These results showed that DIN retention was offset by export of total organic N resulting in net loss of total N from the restored creek. Seasonal variation in DIN retention was significantly and positively related to tidal exchange volume and ecosystem metabolism (gross primary production and respiration). Our findings show that existing methods for measuring nutrient retention in nontidal streams can be adapted to the bidirectional flow patterns of tidal streams to assess restoration effectiveness.

Echoes of the Dough Birds

October 28, 2014

By Bryan Watts, Center for Conservation Biology 

Like a summer carnival coming to a Midwestern town, wherever Eskimo Curlew went their arrival was the most anticipated event of the year. They were travelers along the Great Circle. From breeding grounds around the Mackenzie River they flew east to the Canadian Maritimes before making a nonstop flight to South America. Incredible numbers wintered on the campos around Bahia Blanca south of Buenos Aires. In the spring they flew north to Texas then on to the Platte River before returning to breed on the Mackenzie.

They were loved wherever they went. Described as the most delicious of all shorebirds, they appeared on the menus of posh restaurants in Buenos Aires, New York City, Boston, Chicago, St. Louis and New Orleans. They were canned and shipped to wealthy epicures in London. Hunters from the northeast called them dough birds because when they were hunted in the fall the birds carried so much fat that when they dropped to the ground they occasionally split open, revealing the white fat that appeared like balls of bread dough.

When demand drove their price above 75 cents each, the traveling dough birds became a moving industry. By the 1870s they were hunted somewhere every day of the year. The Honorable F. C. Berteau, a custom’s agent, describes coming into the Hudson Bay Company’s store in Cartwright Labrador and seeing 2,000 birds hanging that were shot by market hunters the same morning. Professor Myron Swenk from Nebraska describes the spring hunters from Omaha shooting flocks on the plains until they filled their wagons and had to put on higher sideboards. After successive years of low numbers, George Mackay, a sportsman from Nantucket, polled two Boston dealers in 1890 who indicated that they had received twenty barrels of birds from the Midwest including eight barrels of dough birds and twelve barrels of golden plovers and dough birds.

By the end of the 1890s the traveling carnival was over. The weight of a relentless harvest had broken the back of the population and it fell into a hopeless death spiral. By the 1930s, final sight records had been recorded over much of its former range. The last individual known to science was shot on September 4, 1963 over a shooting swamp on Barbados, one of several shorebird-hunting holdouts that persist to this day. This September marks the 51st anniversary of that last confirmed bird, now preserved forever in the Academy of Natural Sciences in Philadelphia.

In the early 1900s, during the later years of the decline, many hunters lamented the loss of the population. Dough birds were a significant component of local cultures. The sight and sounds of flocks writhing over the horizon marked the seasons and filled everyone with a sense of life no matter how bleak the day. Today, there is no living link to those experiences. We have only the few written words to bridge the gap of time. Henry Hall from Massachusetts sums up the disconnect stating, “Our chief reminder of its former status is an occasional dusty decoy for sale in some antique shop….” One of the most charismatic shorebirds in the Western Hemisphere that was once estimated to number between 3 and 5 million individuals, now confined to libraries, museums and antique shops.

As ecologists, we rely on first-hand experience to get to the marrow of a species. We commit years to the effort - we wake up with it, walk with it through the day, and sit with it for months in its habitat. We talk to others about their first-hand experiences. Slowly, through the commitment of years, a vibrant, ecological image begins to take form. We begin to know the species to a depth achieved only with close family members. Despite the demands of our fast-paced world, there are no short cuts to truly understanding another species. But for some species, our arrival on the scene comes too late.

Recently, while conducting shorebird work with the Canadian Wildlife Service, I had the opportunity to spend two evenings on Miscou Island in New Brunswick during the peak season when the curlews would be staging. The island contains extensive heathlands that support dense populations of crowberry, the primary food used by dough birds to lay on the fat needed to make their transoceanic flight to South America. The island was a famous hunting site for the species. Dr. Orne Green spent 30 seasons hunting the area following his retirement in the 1870s as a professor from Harvard Medical School. His and other writings describe the shanties, camps, and hunting blinds positioned to intercept birds along the major flight lines between roosts and foraging areas.

It is utterly impossible for an ecologist to walk through such hallowed ground without conjuring up the ghosts of a species so recently extinguished. What does the architecture of the habitat say about the species that used it? Are there ecological echoes that persist here from their occupation? Has any other consumer come in to fill the vacuum left in their wake? You strain your senses to capture the setting and imagine what it must have been like to be among them - the smell of peat underfoot the sound of the wind pushing the water against the shoreline, the subdued greens of the heath plants.


Wagon tracks extending through the bog are the only reminder of the hunting camps from the 1800s on Miscou Island. Photo by Bryan Watts.

Today, the vast habitat patches on Miscou Island are spectacular – a base of sphagnum covered with a carpet of miniature plants including cloudberry, bog rosemary and sundew. Though very diverse, the plant community presents a low profile, allowing birds to walk unimpeded. There is no evidence of the camps and blinds of Dr. Green’s day. In some areas, every step falls on ripe crowberries that cover the ground in dense patches. There is a peace and an undeniable timelessness here.

It is difficult to find any impression left by the throngs that once stopped in the fall. The carpet of sphagnum is dotted with lichens that must be hundreds of years old. They would have “felt” the footsteps and been brushed by bills of dough birds marching across the heath gorging on fruit. But the lightening that once electrified this landscape is gone. There is no rush of wings dropping from the sky like a waterfall down on the crowberries to feed, just an emptiness that stretches from horizon to horizon.

It is tempting to comfort ourselves in the belief that the dough birds were casualties of a historical moment not destined to repeat itself. A brief time sandwiched between the sharp rise in available firearms and the passage of protective legislation. After all, didn’t we pass the Lacey Act and the Migratory Bird Treaty Act nearly a century ago to protect these species? We would only be deceiving ourselves to find comfort in such an illusion. The extinction of the dough birds was driven by the tragedy of the commons, a force that stretches back before human civilization itself and that is still alive and well today. The market hunters that encountered the birds in different places throughout their annual cycle were more concerned about their own profits and enjoyment than they were about the future of the birds or about the other hunters along the Great Circle. We may legislate hunting regulations, but what about the destruction of critical habitat, the consumption of coastal resource or human-caused climate change? Until we are all able to rise above our own self-centered concerns to see a future beyond our own and recognize that cooperation is not merely a kind gesture but an imperative for the future, no species is secure, not even our own.

Navigating a survey to save a species

October 7, 2014

This past summer, researchers for the Center for Conservation Biology (CCB) embarked by boat almost every night in a race to help the Atlantic Coast’s most imperiled bird. Over the past 15-20 years, black rail populations have rapidly declined to dangerously low levels that place them at risk of extirpation. Determining exactly where black rails still occur is the critical first step towards their conservation. CCB is leading focused survey efforts in North Carolina and Virginia to gather the information needed to help ensure their long-term survival. However, surveying for this species befalls a particular set of logistical challenges. Black rails require high marsh zones within some of the Atlantic Coast’s most remote locations. Most of these areas can only be accessed by boat during high tide. In addition, black rails vocalize most reliably at night, so the best survey times coincide when navigating waterways can be most treacherous for survey teams.

In North Carolina, Zak Poulton and Katie Rittenhouse piloted the CCB’s 17-ft Maycraft up narrow channels, across the mouths of rivers, and on the big waters of the Pamlico Sound. They were relying only on a depth finder, the on-board GPS, and a keen mariner’s sense to avoid the pitfalls of nocturnal navigation, such as running aground or taking on too big a wave. Zak and Katie’s efforts were being matched by Fletcher Smith and Jake McClain, who were conducting parallel surveys for black rails in the Chesapeake Bay and Barrier Island lagoon system of Virginia. Both survey teams had a common approach: visit as many accessible high marsh locations as possible throughout the season using a game caller to broadcast the not-so-familiar “ki-ki-kerr” and other black rail vocalizations at high volume in an attempt to increase detection from responding birds. Black rails exhibit some of the most enigmatic vocal behaviors among all birds in the United States. Their calling rates are irregular and appear to be moderated by unknown factors. A visit to a black rail marsh can produce calling birds one night and be silent the next. Because of this, the biologists re-visited these locations three times during the season.

The North Carolina survey project marked the first time that a broad-scale, systematic survey for black rails has ever taken place in the state. Previous efforts conducted by researchers have only focused on surveying small sets of marshes. Our study is being funded for two years by the North Carolina Wildlife Resources Commission in an effort to document distribution and habitat use and to create a first-of-its-kind population benchmark for the state. However, this is the second time we have conducted a systematic, state-wide effort in Virginia. Both the 2014 summer survey and a previous effort conducted in 2007 in Virginia were funded by the Virginia Department of Game and Inland Fisheries and were designed to produce the same level of information as North Carolina.

Black rails were detected at 15 of 153 locations visited by Zak and Katie in North Carolina. However, 9 of these locations were directly adjacent to one another along the stretch of Highway 12 that bisects Cedar Island (Carteret County). The remaining sites were scattered throughout coastal marshes in the southern half of the state and only accessible by boat. Next year we will survey the Albemarle Sound region and the Outer Banks.

Black Rails are dependent on the high marsh for breeding but may also use the ecotone pictured here for foraging purposes. Photo by Bryan Watts.

The Virginia survey results tell a tale even grimmer than what we discovered in 2007. Seven years ago we determined that black rails were at very low population levels and only occurred at 12 of 328 surveyed locations. Black rails had disappeared or were reduced in numbers at some of the most widely known locations in the state. This past summer, black rails were only detected at 1 of the 12 locations previously recorded in 2007 and were not found at any of the 123 other sites. The lone holdout marsh at Saxis, which was known throughout the 1980s and 1990s to harbor as many as 25 black rails, appears to be gasping its last breath for this rail with the detection of only 2 birds.

The Center for Conservation Biology is committed to creating the information resources needed to formulate the best management approaches to save this species. Black rails are on a crash course for extirpation. Without management intervention, it is likely that the black rail will disappear from many of last remaining places it occurs in our lifetime. Black rail existence on the Atlantic coast is threatened by sea-level rise, nest predators, and incompatible management of marshes, such as mosquito control, deepwater impoundments, or the ill-timed use of prescribed fire.

An eco-experience: Wading into wetlands

October 15, 2014

On Saturday, October 4, VCU Rice Rivers Center hosted its third EcoExperience, entitled “Wading into Wetlands: An Amphibian's Eye View of Some Exceptional Ecosystems”. Participants from the general public were treated to a special day of donning waders and experiencing wetland science from a researcher’s point of view.

Wetland habitats provide numerous ecosystem services such as clean water, clean air, and critical habitat for threatened and endangered species and increased regional biodiversity, and are among some of the most productive ecosystems on the planet. Participants learned about these critically important, yet highly imperiled, wetland ecosystems and engaged in hands-on exploration of some diverse and unique wetland resources located at the VCU Rice Rivers Center. Participants investigated forested and herbaceous dominated tidal/non-tidal and ephemeral wetlands along the banks of the James River.

Additionally, some “Experiencers” planted bald cypress seedlings as part of the wetland restoration of Kimages Creek and its surrounding areas, a long-term project of VCU, The Nature Conservancy, U.S. Army Corps of Engineers, American Rivers and the National Oceanographic and Atmospheric Administration. The project encompasses the original 70 acres of lake bottom (formerly Lake Charles, created by a now-removed dam) and 1.5 miles of tidal creek to their natural hydrology and ecosystem functioning.

Saturday’s EcoExperience was the final installment of the series for 2014. A series of EcoExperiences for 2015 is being developed as a way to further welcome and engage the general public in the exciting and vital work that is being done at the Rice Rivers Center.

Spawning reefs offer recovery strategy for sturgeon in the James

October 7, 2014

The Atlantic Sturgeon once supported a major Chesapeake Bay fishery and was among the oldest, largest, and most iconic species along the Atlantic coast. In response to habitat loss, pollution, and over-fishing, Atlantic Sturgeon abundance declined dramatically and, as recently as the early 1990s, some biologists believed that the species was extirpated from Chesapeake Bay. However, small numbers of sturgeon did persist in a few coastal rivers, including the James River of Virginia; most U.S. populations were listed by NOAA as federally endangered in 2012. As part of ongoing research and recovery efforts for James River Atlantic Sturgeon, three spawning reefs were constructed in the James during the period 2010-2013 by the James River Association (JRA) and Virginia Commonwealth University’s Rice Rivers Center (VCURRC), with support from USFWS, National Fish and Wildlife Foundation, The Nature Conservancy, Luck Stone, and Vulcan Materials.

Each reef is about one-half hectare in size and was constructed with aggregate from local sources. Site selection was based on a number of criteria, including river depth, salinity, and proximity to known migration corridors. Habitat mapping by VCURRC, USGS, and NOAA suggested that the availability of clean, hard substrate — necessary for successful sturgeon spawning — may limit recovery in the James, which experiences high rates of sedimentation from watershed sources. Post-construction monitoring of reefs by VCURRC and JRA employed a wide array of gears, including egg mats, nets, and acoustic telemetry, and utilization has been documented for several migratory and semi-migratory fishes, including white perch and Alosa spp.

Unfortunately, no eggs of Atlantic Sturgeon have yet been recovered from the reefs but limited monitoring will continue, as resources permit. For more information on this program, contact Greg Garman at ggarman@vcu.edu.

The team sport of peregrine hacking

October 7, 2014

Courtney Turrin and I arrive on the Benjamin Harrison Bridge over the James River near Hopewell, Va. just after 7:15 a.m. A call to the tenders closes the bridge just long enough for us to unload gear in the control tower. The historic drawbridge has massive twin lift towers that rise more than 300 feet above the water. We carry gear to the north tower landing and attempt to call the cable elevator with no success. Rain the night before had shorted the elevator, so we prepare additional gear for the long climb up the outer ladders to reach the upper catwalk and the falcon nest box that The Center for Conservation Biology (CCB) installed in the late 1990s. Halfway up the ladder, the adult peregrines begin to wail and stoop.

As we reach the top of the lift tower, Libby Mojica, 50 miles to the north, meets up with a crew from the Virginia Department of Transportation near the base of the Norris Bridge across the Rappahannock River. Included in the group is environmental specialist Theresa Tabulenas, an entire snooper truck crew, a traffic control crew, administrators and local reporters. Before the convoy begins to move onto the bridge, Bart Paxton launches a boat and takes a position under the bridge in case a young falcon attempts its first flight. The pair of falcons on the Norris Bridge nest on a beam directly under the roadbed and more than 100 feet above the water. A specialized snooper truck with a boom capable of extending out and curling up under the bridge is the only possible access to the nest. Once in place, Libby, Theresa, and a truck operator climb inside the small bucket and begin the carnival ride out over the river. Just as they are retrieving the brood, Courtney and I have arrived back in Williamsburg. Marie Pitts and Courtney band the two young peregrines and place a strip of colored tape on one of the bands on each bird to make it easier for hack attendants to identify the birds on the wing.

As Libby concludes the banding event in a parking lot near the Norris Bridge, Jake McClain, a student intern at CCB, begins to prepare a vehicle to transport the peregrines west. Jake and Ashley Lohr, a biology student attending Virginia Tech and summer intern for Shenandoah National Park, will meet halfway between Williamsburg and Shenandoah to transfer the birds, and Ashley will drive the birds to the park. Libby arrives in Williamsburg in the early afternoon, handing off the birds to Jake. Ashley will have the birds in their hack box by early evening.

Rolf Gubler, a biologist with Shenandoah National Park and an expert at managing peregrine releases, has been preparing for the hack. Weeks before the transfer of birds, Rolf and Sergio Harding from the Virginia Department of Game and Inland Fisheries secured a seasons supply of captive-reared quail to feed the peregrines. A week before, Rolf had taken the two custom-made hack boxes from storage and put them in place on Hogback Mountain in the park. Rolf and Ashley place the birds in the boxes upon arrival and the birds are fed daily until ready for release at fledging age. After release from the box, the birds continue to be fed until they learn to hunt on their own and disperse from the site. Three different cohorts of birds are brought to the site for release over the course of the breeding season.

During the several-weeks-long transition to independence, Rolf and Ashley monitor the birds daily, keeping a log of each individual’s presence and activity. The colored tape placed on the bands facilitates the identification of each bird. Mitchell Byrd and I visited the hack site with Rolf and Ashley during the last release of the season. Mitchell is the great grandfather of peregrine reintroduction in Virginia, having started the release of captive-reared birds back in 1978. On this day, we were both treated to the sight of 8 young falcons on the wing coming and going to feed and whirling out over the valley below. Standing out among the birds was yellow, the bird that Courtney and I had taken from the Benjamin Harrison Bridge earlier in the season.

Since the 2000 breeding season, we have translocated 235 young falcons produced by coastal pairs to the mountains for release. Translocation has been part of an integrated restoration program. Moving the young from the mountains increases the survival of young hatched on bridges and buildings where mortality is notoriously high, reduces the impact on migratory shorebirds, and provides the opportunity to strengthen the mountain population.

The translocation program has many moving parts and would not be possible without a team effort. We thank all of the agencies and individuals who are committed to peregrine conservation and who make the effort possible.

Franklin Military Academy studies water quality

October 7, 2014

On October 3, students from Franklin Military Academy’s Earth and Environmental Science class visited the Rice Rivers Center to learn about water quality monitoring. The class, accompanied by their teacher, Kathy Paschall, began their visit on the research pier. VCU’s Dr.Paul Bukaveckas taught the students about the monitoring equipment, as well as water quality and sampling. Afterward, the class was shown some of the real-time monitoring data and was instructed on how to interpret them. The class collected water samples from both the James as well as Kimages Creek in order to compare and better understand differences in nutrient concentrations. The instrumentation used to monitor the water quality is part of VCU’s Mountains to the Sea collaboration that includes the VCU Rice Rivers Center, VCU’s Center for Environmental Studies, Washington and Lee University and Randolph-Macon College, as well as the United States Geological Survey.

Red knot decline spreads to Virginia

September 8, 2014

The rufa subspecies of the red knot has experienced a dramatic decline over the past three decades. Evidence of the decline has come from long-term population assessments and surveys of both a major spring staging area, Delaware Bay, and the largest known overwintering site, Tierra del Fuego. The decline has led to its listing as an endangered population in Canada, its declaration of endangerment by the Convention on the Conservation of Migratory Species, and a recent proposed rule change to the United States Fish and Wildlife Service to include the population on the list of threatened and endangered wildlife.

Prior to this year, one of the conundrums in the broader decline of rufa knots has been the stronghold of the Virginia Barrier Islands. Despite being less than 100 kilometers south of Delaware Bay, declines in staging red knots had not been documented in Virginia. Long-term aerial surveys of the islands conducted by Bryan Watts of CCB and Barry Truitt of The Nature Conservancy had not detected a statistically significant trend in use. However, following the compilation of the 2014 surveys, this pattern has changed. With the addition of the 2014 surveys, an examination of “knot days”, an index of seasonal use of the islands, has revealed a significant decline across decades.

Most of the early explanations forwarded to explain the decline in the rufa population focused on spring foraging conditions within Delaware Bay, where estimates of staging birds have declined by 60 to 80 percent. Red knots using Delaware Bay depend almost exclusively on eggs from spawning horseshoe crabs to replenish fat reserves before making their final flight to arctic breeding grounds. Commercial overharvest of horseshoe crabs has been suggested as a driver of observed declines. Unlike Delaware Bay to the north, the Virginia Barrier Islands do not support significant horseshoe crab spawning events. In Virginia, staging red knots depend on clams and mussels to build fat reserves. If early explanations for the decline are correct and the prey conditions within mid-Atlantic staging sites are the root cause of declines, then declines in Virginia may raise concerns for the local clam and mussel populations. If the primary cause of declines resides elsewhere, such as arctic breeding grounds, then trends within staging areas may only reflect conditions in these other locations. The most likely scenario is that the population is experiencing multiple stressors throughout its annual cycle.

Banding woodpeckers

August 27, 2014

By Bryan Watts, Center for Conservation Biology

For endangered red-cockaded woodpeckers, banding day is the culmination of more than a month of careful preparation. The season begins in early April with 4AM wakeup calls, ferry rides, and walks through quiet woods to take up positions around roost trees before birds begin to emerge. The breeding male sounds reveille each morning, calling the clan out of their cavities to muster within a common rallying area. The birds interact here before moving off to forage. This short social event is the best time of the day to get a headcount and to identify each individual within the breeding group. CCB biologists led by Mike Wilson spend two weeks each spring systematically moving through all of the breeding clusters within Piney Grove Preserve to see who has survived the winter. This spring check is one of two population assessments during the year but is also an opportunity to get an early read on the upcoming breeding season.

The egg vigil begins during the third week of April. Nest cavities are checked every four days for the appearance of the first eggs. A peeper scope is inserted into the cavity from below to view its contents on a small video screen on the ground. Knowing when the eggs are laid and, by association, when the chicks will hatch is critical to successfully banding the brood later in the season. Young are banded within a narrow window between the age of five and ten days. Before five days old the tarsus is too short to hold the full band combination. After ten days old their eyes open and they are considerably larger, making it more difficult to extract them safely from the cavity. Once the hatching date is known, biologists schedule return visits on dates that allow broods to be banded when they reach the optimal age.

Banding day is always a special event for both biologists and woodpeckers. Nest cavities range in height from 30 to 60 feet, and Swedish climbing ladders are used to reach the cavities. The ladders are light weight and come in ten-foot sections that are secured and stacked as the climber ascends. For most cavity trees, they are ideal equipment because they are relatively easy to install and do no damage to the tree. Once the nest cavity is reached, young are carefully extracted through the entrance with a noose and lowered to the ground for processing.

The young are inspected for condition and age and then banded and weighed. They grow and change in appearance so rapidly that they are easily aged to the day. Each bird receives a numbered aluminum band and a unique combination of color bands that will allow biologists to identify the bird throughout its life. Having the entire population banded in this way allows us to see who remains in the population and to track their genealogy over time. Once banded and weighed, the brood is returned to the cavity.

All of the young produced in the population are checked again in the first three weeks after fledging. Still dependent on the adults, the young are located and identified with spotting scopes to see who has survived to fledging age and to determine gender. In the first few weeks after fledging, males retain the red patch of feathers on the crown for which the species was named. The red cockade is lost by early fall, making gender determination much more difficult.

For red-cockaded woodpeckers and many other species, banding is a tool that allows us to collect demographic and other data that facilitate management decisions. CCB is fortunate to work with great partners, including The Nature Conservancy, Virginia Department of Game and Inland Fisheries, and the U.S. Fish and Wildlife Service. All of these organizations are devoted to the recovery of the woodpecker population in Virginia.

National Eagle Roost Registry launched

October 1, 2014

By Bryan Watts, Center for Conservation Biology

Non-breeding bald eagles are extremely social and frequently roost together near rich food resources. Communal roosts may be ephemeral congregations of birds that form to exploit short-lived food resources or may be used for decades. Roosts may be used by hundreds of birds or just two or three depending on the circumstances and the surrounding landscape structure. Because communal roosts play an important role in the life cycle of bald eagles they are protected under the “disturb and sheltering” provisions of the federal Bald and Golden Eagle Protection Act (Eagle Act) of 1940and their management is considered within the National Bald Eagle Management Guidelines. However, since the establishment of formal management policies during the late 1960s, communal roosts have been the red-headed stepchild of management activities.

Despite similar protections afforded under the Eagle Act for roosts and nests, most management programs have focused primarily on nesting sites. One of the primary impediments to protecting communal roosts is the lack of information on their location. Eagle roosts are often positioned within remote areas and are notoriously difficult to locate from the ground. Delineating a single roost may take multiple biologists several early morning and late evening sessions to triangulate flight lines of birds moving in or out of active roosts. Because of the high investment required to find roosts, we have very little systematic information on their distribution. However, with the increased use of satellite transmitters programmed to record night locations, information relevant to roost networks is growing rapidly.

With funding from the U.S. Fish and Wildlife Service and the American Eagle Foundation, The Center for Conservation Biology (CCB) has been delineating and compiling roost locations throughout North America. The first phase of this project has been to use CCB’s extensive bald eagle tracking database to delineate roosts throughout eastern North America. A second phase focuses on data from other tracking projects that have information relevant to communal roosts. To date, more than 1,000 roosts have been mapped across 17 U.S. states and 5 Canadian provinces.

In early September, CCB launched an online Eagle Roost Registry that will begin the process of removing the information barrier to roost protection. The registry is an ongoing program. We are requesting information from eagle tracking projects and individuals who wish to contribute to eagle conservation by improving the state of knowledge about eagle roosts.

The blueberry birds of Acadia

August 19, 2014

Over the songs of Swainson’s thrush and white-throated sparrows come the soothing calls of approaching whimbrels. Soon 24 birds in formation appear over the tree line and begin a wide circle over the blueberry field. As they approach the northeast corner of the field, two shots of screamer shells explode from a black truck, leaving white trails of smoke arcing toward the flock. The flock whirls east, rising higher and picking up speed. With each circle two trucks reposition themselves along a perimeter road to cut off any descent. The flock circles the field 18 times over 12 minutes before breaking off in defeat and flying out of view to the north. This cat and mouse scene is repeated throughout the day as flock after flock look for a chink in the armor that would give them a respite to feed on the lush blueberries. The blueberry wardens, charged with protecting a valuable crop just two weeks from harvest, would emerge with a perfect record after turning away all comers.


Blueberry yield on the Acadian Peninsula is tremendous varying from 2,000 to 8,000 pounds per acre. Photo by Bryan Watts.

The whimbrels have come here to the Acadian Peninsula of New Brunswick from their distant breeding grounds around the Mackenzie Delta in the Northwest Territories by way of the Beaufort Sea. After the breeding season, they fly north to islands in the Beaufort Sea to feed and prepare for the 4,500-kilometer flight across the continent to Atlantic Canada. Here they arrive depleted and must prepare for the longest nonstop flight of their annual cycle, a 6,000-kilometer journey over the open Atlantic to winter grounds on the coast of Brazil. It will take all the fat they are able to carry to get them there. They have only three weeks to prepare.

I have come to the peninsula with Fletcher Smith from CCB to work with Julie Paquet from the Canadian Wildlife Service to quantify whimbrel use of the peninsula and to observe the interaction between whimbrels and the blueberry farmers. The population of whimbrels using the Atlantic Flyway has been declining by 4 percent per year since the mid-1990s. High on the list of conservation priorities is to understand how the species is faring within strategic staging areas like the Acadian Peninsula. We flew aerial surveys to determine use of blueberry fields, natural heathlands, peat mines, and barrier islands. We conducted ground surveys to quantify bird density within blueberry farms. We spent the evenings locating night roosts with Lewnanny Richardson from Nature New Brunswick (http://www.naturenb.ca/) and Kirsten Snoek, a summer student working with the Canadian Wildlife Service. And finally, we made observations of whimbrels interacting with the blueberry wardens.

During the past decade, the demand for wild lowbush blueberries has skyrocketed, producing a rush of corporations and family farmers intent on riding the blue wave. Recognized widely for their heart-healthy qualities, blueberries from the Canadian Maritimes and Maine have become a global brand. Revenues in New Brunswick alone have tripled since the early 2000s, increasing by $2.5 million per year. By 2012, the province supported 220 growers tending 33,000 acres that produced 45 million pounds of berries and revenue of $31 million. In 2013, the province produced a five-year strategic plan that called for the development of at least another 20,000 acres of blueberries and a target production of 3,000 pounds per acre. In a recent announcement, a major grower revealed a plan to invest $200 million dollars in increased blueberry production and processing capacity on the Acadian Peninsula. Currently, the two major corporate players in the region are clearing tens of thousands of acres of boreal forest to ramp up production.

Whimbrels have apparently come to the peninsula for thousands of years to prepare for their transoceanic flight. Accounts of shorebird hunting on Miscou Island (the northernmost point on the peninsula) from the late 1800s placed them alongside Eskimo curlew and other species feeding on blueberries and crowberries within the natural habitats. A story in The Sportsman from the 1870s describes a collection of hunting camps and blinds dotted across the heathlands.

The blueberry crop is protected by a loose network of local wardens assigned to individual farms. Many wardens move campers onto the farms beginning a month before harvest. They are there to protect the berries from local rustlers and from natural consumers like whimbrel. Some of the wardens refer to the whimbrels as “Le Mangeur de Bleuets” or blueberry eater and believe that they are capable of consuming enormous quantities of berries in a single sitting. This view has made the whimbrel persona non grata on the peninsula and the target of a well-intentioned campaign to reduce crop damage. The wardens use several techniques to dissuade the birds from landing, including scarecrows of many forms, air cannons that go off on an irregular schedule, broadcast raptor calls and guns with loads designed to scare the birds or, on occasion, to kill them.

The Le Mangeur de Bleuetsmay not live up to its legend. Based on metabolic requirements and blueberry nutritional values, a whimbrel would be capable of consuming a maximum of just over 1.5 pints of berries per day. Considering an average wholesale price, this consumption equates to 52 cents of product.

The question of whimbrels or blueberries is but one example of the grand conservation question that is echoed over and over across the planet. It is embedded within the DNA of the conservation dilemma. In general terms, how much stuff is the collective “we” willing to give up in order to insure the future of other species that share the planet? In a farm-gate crop of more than 65 million pints, are we willing to concede 0.038 percent to hear the calls of whimbrels approaching overhead? This August sound is just as big a part of this ancient landscape as the blueberries themselves. We continue to struggle for an answer to this basic question that calls for a tradeoff between economic return and core human values. Of course we are not just deciding for ourselves. These same birds are also welcomed in Brazil, the Gulf Coast of Texas, the Platte River in Nebraska, and the farm fields of Saskatchewan.

The irony of the present strategy is that by constantly churning up the whimbrels, the wardens are actually increasing the energy requirements of the birds and unwittingly increasing the overall blueberry consumption. In effect, by paying to disturb them, they are compounding the loss.

Rice Rivers Center announces Mountains to the Sea collaboration

July 29, 2014

VCU Rice Rivers Center is pleased to announce the formation of a new partnership among Randolph-Macon College, Virginia Commonwealth University, Washington and Lee University and the United States Geological Survey (USGS) that will provide students with the opportunity to test the water quality of the James River.

Partnerships

This new partnership is a first-of-its kind, real-time water quality assessment network in a large coastal watershed and its estuary. It also represents a unique and innovative collaboration with higher education, government and corporate supporters. The four-year project, “From the Mountains to the Sea,” includes research and education components and is funded by the Jessie Ball duPont Fund, MeadWestvaco Foundation and Dominion Virginia Power. In addition, the Virginia Department of Environmental Quality (VA DEQ) has donated laboratory analysis for the project.

“The health of the James River and the vibrancy of the Virginia academic community are important not only to MWV’s business, but also to the communities where we live and work,” said John A. Luke, Jr., chairman and chief executive officer, MWV. “The MeadWestvaco Foundation is proud to support the sustainability of both through this unique partnership with Randolph Macon, VCU, Washington & Lee and the USGS.”

“This research and educational partnership will improve the student and faculty experience at VCU as we emerge as one of our nation’s premier urban public research universities, and it will also lead to a more thorough understanding and effective management of the waterways upon which we depend each day,” says Michael Rao, Ph.D., VCU’s president. “VCU looks forward to strengthening its connection with these partners and with America’s founding river.”

Unique opportunities

“This project will give our university partners access to cutting-edge technologies for measuring, interpreting, and using water quality information in ways that will support the effective management of large coastal rivers and the living resources that depend on these ecosystems,” says Greg Garman, Ph.D., research director at the VCU Rice Rivers Center.

The sophisticated sensors—one in Cartersville, Virginia and one along the lower James River near the VCU Rice Rivers Center—will be installed to measure pollution. An additional type of sensor will be used to measure the amount of tidal water moving up and down the river on a continual basis. The sensors will be installed by USGS with the assistance of students during their internships—one each from R-MC, VCU and W&L—who will be trained by USGS experts. Ultimately, the data collected may indicate the amount of pollution (much of it caused by fertilizer) that ends up in the Chesapeake Bay. The data collected will be available to the public in real-time on a web site maintained by the USGS.

Student interns

USGS will provide extensive training this summer for the three student interns. Once trained, the interns will share their knowledge with other students. At R-MC and W&L, the interns will return to campus in September and then lead other students in conducting USGS-style monthly sampling on a stream near each home institution. VCU will also expand opportunities for student engagement in water quality assessment in and around the Rice Rivers Center.

The USGS is committed to helping to shape the next generation of scientists to collect precise, consistent, and accurate data for the nation to facilitate understanding and management of the environment.

Partners in education

“This collaboration builds on the strengths of the various partners by providing students from VCU, RMC and W&L an opportunity to learn techniques for environmental monitoring from our colleagues at USGS and to use these skills in research projects conducted with faculty at their home institutions,” says VCU Professor Paul Bukaveckas. “For the faculty and scientists involved, it provides an opportunity to work on a shared dataset and improve our understanding of water quality in the James.”

Update on VCU’s long-term studies of the Prothonotary Warbler along the lower James River 2014: Geol

July 23, 2014

Between June 16 and June 26 , 25 geolocators were deployed by Team Warbler members from VCU and J. Sargeant Reynolds Community College at two study sites along the upper James River (Presquile National Wildlife Refuge and Deep Bottom Park). The units were deployed on 19 females and six male Prothonotary Warblers, at least two years of age, and with active nests. These birds that are two years old or older that have nested a second year at a specific site have the highest return rates in subsequent years. All individuals fitted with geolocators continued to be monitored by Team Warbler to ensure the units remain in place and do not interfering with normal nesting activities.

Prothonotary Warblers provide an ideal research model for Neotropical migratory species because they readily utilize artificial nest boxes and have a high tolerance for handling, making them easy to capture and monitor over long periods. In addition to the James River population in Virginia, Prothonotary Warblers currently are being monitored by researchers across their breeding range including research initiatives in Illinois, Arkansas, South Carolina, and Louisiana. However, data gaps still exist regarding migratory pathways and geographic (migratory and genetic) connectivity among populations occupying breeding and wintering habitats. Understanding the connections between breeding and wintering ranges is essential to informing conservation strategies going forward.

To that end, a group of conservation partners comprised of several federal, state, non-government organizations (NGOs), and universities including Virginia Commonwealth University and its Audubon partners, are working to better understand the full life-cycle of the Prothonotary Warbler. The research partners are utilizing cutting-edge technologies, including stable isotope analysis, population genetics, and deployment of geolocators (miniaturized solar light-logging devices) to track Prothonotary Warbler migratory routes in order to understand the ecology and conservation needs of migrant birds throughout the entire annual cycle.

The first year of the project is a trial study involving deployment of 50 geolocators on Prothonotary Warblers at two sites (Virginia and Louisiana). The geolocators being deployed are smaller than used previously on Prothonotary Warblers, and have specially designed light stalks. The small size and angled aspect of the light stalks are designed to decrease weight and drag, maximizing return rates of individual birds carrying the units. The birds have to be recaptured upon return to the breeding grounds in 2015 in order to download the data from the geolocators. The data should provide information on the species’ migration routes, timing, duration and location of tropical wintering grounds.

Funds toward purchasing geolocators and conducting stable isotope analysis have been generously provided by the VCU Center for Environmental Studies, the U.S. Fish and Wildlife Refuge System and the Norcross Wildlife Foundation through a grant to the Virginia Audubon Council.

Three-year grant funded for oyster restoration study

July 23, 2014

Oyster reef restoration benefits, in terms of enhanced production for economically and ecologically important fishery resources, is receiving increased attention due to widespread loss of the habitat and increasing demand for sustainable seafood from intact reef ecosystems. In response to this, “Pathways to Production: An assessment of fishery responses to oyster reef restoration and the trophic pathways that link the resource to the reef” is being funded through NOAA’s Chesapeake Bay Fisheries Science Program. Dr. Steve McIninch of VCU's Center for Environmental Studies is the Principal Investigator on the study.

The Piankatank River, a sub-estuary of the Chesapeake Bay, is a focal point for large-scale oyster reef restoration. Many agencies are involved, most notably NOAA, The Nature Conservancy, VMRC, and the Army Corp of Engineers. VCU Rice Rivers Center is leveraging this construction, and partnering with TNC, to examine how the fish community responds to the restoration and maturation of these constructed reefs. The three-year study will allow for community research both before and after new reef construction, as well as comparisons with existing established reef communities. Standard collection methods will be used (traps and nets), as well as a hydroacoustic array to quantify movements of fish on and off the reef.

The new reefs are being constructed with concrete and so will take some time to become colonized by oysters and other marine organisms. This will also afford the opportunity to assess the differences between simple structure (concrete) and a mature reef. One of the more difficult aspects will be to examine the contribution that reefs have to non-resident fishes that may be of commercial importance. So, how does an adult bluefish or red drum that does not stay on the reef benefit from the reef aside from occasional habitat? This question will be examined by using diet analysis and stable isotope examination of both predator and prey, allowing the charting of a trophic pathway to and from the reefs.

As a valued cooperator to this project, The Nature Conservancy is actively engaged in oyster restoration in Virginia and will be constructing up to 74 acres of oyster reef in the Piankatank River over the next two years. Using a $500,000 grant along with other private donations and state (VMRC) matching funds, 31 acres of reefs will be constructed to provide seed oysters and an additional 43 acres of sanctuary reefs (no commercial harvest permitted).

Another crowned eagle shot

July 18, 2014

By Bryan Watts, Center for Conservation Biology

In June, The Center for Conservation Biology (CCB) received news from Argentina that another crowned solitary eagle had been shot.

This bird was one of 12 individuals being tracked with satellite transmitters as part of a collaborative study between the Center for the Study of Birds of Prey of Argentina (Centro para el Estudio y Conservación de las Aves Rapaces en Argentina http://www.cecara.com.ar/), located within the Universidad de La Pampa, The Center for Conservation Biology, and The Peregrine Fund (http://www.peregrinefund.org/). The broad study was designed to investigate dispersal and movement patterns during the juvenile stage, a period during the life cycle of crowned eagles that biologists know nothing about.

The bird was initially marked in 2012 along with five other nestlings. Only a single bird of this initial cohort is still on the wing. Two of the birds have been shot and two have been electrocuted.

This remarkable eagle is critically endangered with a declining global population estimated to be well below 1,000 individuals. The species is classified as endangered on the IUCN Red List (http://www.iucnredlist.org/details/22695855/0), is included on the threatened lists of both Brazil and Argentina and is presumed extirpated in Uruguay with no reported sightings since 1933. Extremely little is known about crowned eagle population biology and basic ecology.

The shooting of these individuals is senseless. Crowned eagles feed almost exclusively on snakes and armadillos and pose no threat to any domestic animals. The crowned eagle has a very low reproductive rate, producing a maximum of only one young per year. This life history strategy is not sustainable without relatively high survival. In addition to habitat loss, juvenile and/or adult mortality from human sources may play an important role in the continuing decline. The ongoing tracking study is intended to quantify survival to breeding age. Four birds still remain from the 2013 cohort and two remain from the 2014 cohort.

Wetland restoration update

July 22, 2014

Restoration of the 70-acre wetlands at the Rice Rivers Center is proceeding apace. Subcontractors from The Nature Conservancy have planted approximately 15,000 trees and shrubs, and an additional 10,000 plants will be planted in the fall. Vegetation monitoring starts this summer under the supervision of Dr. Ed Crawford, using undergraduate and graduate student research assistance. Dr. Len Smock, the Rice Rivers Center director, is conducting stream monitoring of Kimages Creek.

The overarching goal of the project is to restore the wetland to the state it was in before the area was dammed to create Charles Lake in the early 20th century. Researchers have examined stumps that remain from that era, and are replacing similar species in the wetlands as were originally there. Each stump is being geo-located to accurately plant replacements.

The method for identifying the original trees is multifaceted: cross-sections of stumps (“stump cookies”) are cut and brought into the lab, sanded down and identified. Graduate student Richard Ward has developed an 11-step process to identify species and determine the average age of the trees.

This process has been completed on approximately 10 percent of the stumps. A total of 4,500 stumps have been found and geo-located. It has been determined that there are approximately 15-20 species of trees native to the wetland.

With the assistance of the U.S. Army Corps of Engineers, drones carrying high-tech instrumentation are being used to create high-resolution images of the wetland to help gauge the success of the restoration efforts.

Osprey return to the Elizabeth

July 18, 2014

By Byran Watts, Center for Conservation Biology

During the height of the DDT era, breeding ospreys along the Elizabeth River in Virginia disappeared completely. Some 30 years later, when the Center for Conservation Biology (CCB) surveyed the Chesapeake Bay osprey population, the tributary still seemed to be frozen in time. During the historic survey of 1995, only 8 breeding pairs were found. Unlike the other vibrant creeks, rivers and bays of the estuary where ospreys were thriving, piloting a survey boat along the Elizabeth gave an eerie flashback to the 1960s and 1970s. Like its sister superfund tributaries the Anacostia and Baltimore Harbor, the Elizabeth was a ghost town full of empty nesting structures.

In 2000 and 2001, wildlife contaminants expert Barnett Rattner from the Patuxent Wildlife Research Center collected egg samples from the Elizabeth River, Anacostia River, and Baltimore Harbor to compare to three “clean” tributaries. During this period, eggs collected within the Elizabeth still contained elevated levels of DDT derivatives and various industrial compounds. However, productivity was not suppressed and eggshell thickness, an outward indicator of pesticide problems, had nearly recovered to pre-DDT levels.

Now, more than 40 years after the federal ban on DDT, osprey pairs are returning to the Elizabeth River in numbers. During the 2014 breeding season, CCB along with staff from the Elizabeth River Project (http://www.elizabethriver.org/)resurveyed the entire tributary, mapping 60 breeding pairs and documenting 73 young. One of the more satisfying aspects of the population recovery to date is that 16 of the 60 pairs are nesting on osprey platforms erected by private citizens along the shoreline. Aside from the overall cleanup of the tributary, platforms are one of the most effective management tools we have for the breeding population.

Rice Rivers Center hires full-time data manager

July 23, 2014

We are pleased to announce that Jennifer Ciminelli has joined the Rice Rivers Center as data manager and research coordinator. Jennifer comes back to VCU after gaining extensive experience working in the geospatial technology field. She received her B.S. in Environmental and Forest Biology from the State University of New York and an M.S. in Environmental Science from VCU.

Her work and research experience have involved using geospatial technologies to model change in terrestrial and aquatic environments. In addition, she has worked in IT positions with local government, state government, and the private sector. Her work has included collaborations on environmental applications of geospatial technology as well as management of enterprise geographic systems. Jennifer will be a great asset to the Rice Rivers Center, bringing her interest in the application of geospatial technology to the environmental field in data coordination, collaboration and teaching.

VCU Rice Rivers Center’s latest publication

July 22, 2014

As we approach the fifty-publication mark at the VCU Rice Rivers Center, we congratulate Dr. Michael Fine on his latest article, “Reduction of the pectoral spine and girdle in domesticated channel catfish is likely caused by changes in selection pressure”, by Michael L. Fine, Shweta Lahiri, Amanda D. H. Sullivan, Mark Mayo, Scott H. Newton and Edward N. Sismour, which was published in the July 2014 journal, Evolution: The International Journal of Organic Evolution.

Catfishes are one of the most successful groups of vertebrates, with over 3,000 different species. One of the adaptations that have led to their success is a pectoral spine that looks like a medieval weapon. When locked at a right angle, the spines increase the catfish's size and make it harder for predators to eat them. In this study, Fine and colleagues have shown that domesticated channel catfish that have not experienced fish predation for a number of generations have smaller spines than wild catfish, and that the difference appears to result from changes in selection pressure.

2014 Whimbrel Watch establishes new high mark

June 11, 2014

by Bryan Watts, Center for Conservation Biology

It begins with a nearly imperceptible whistle and then a faint line along the horizon. In minutes the flock will be overhead treating the team of counters to a full chorus of contact calls. Flock after flock of whimbrels follows this same flight line in the last three hours of the evening. By morning they will be in Toronto, some 800 kilometers (500 miles) away. Within five days they will be on their arctic breeding grounds preparing a nest for eggs. The onlookers have come to a dock on Box Tree Creek along the lower Delmarva Peninsula to count the birds as they pass and to see them off on their long, nonstop flight north. The birds have been here in the marshes for three weeks gorging on fiddler crabs and putting on fat to fuel the flight.

Since the spring of 2009, The Center for Conservation Biology and The Nature Conservancy have teamed up to run a “leaving count” of whimbrels around the third week of May. In 2014, the count covered eight days between the 20th and 27th of May and documented 132 flocks totaling 8,249 whimbrels. The 2014 total is a record high for the site and represents a significant portion of the population for the entire Western Hemisphere. In addition to whimbrels, the counters recorded 642 black-bellied plovers, 894 dunlin, and 2,021 short-billed dowitchers leaving for the arctic.

The birds gather, rally up out of the marsh, assemble in V formations, and head north. Until recently, researchers did not know where the birds staging here were headed. A satellite tracking project conducted by the group in this location has demonstrated that the birds represent a mixture from two breeding populations. Some will fly 3,000 kilometers to breeding grounds within the Hudson Bay Lowlands. Others will fly the longer 4,800 kilometers to nest within the Mackenzie Delta in extreme western Canada.

Mulberry sparrows decline

July 18, 2014

By Bryan Watts, Center for Conservation Biology

The population of coastal plain swamp sparrows (Melospiza georgiana nigrescens) breeding within Mulberry Point along the Rappahannock River in Virginia has experienced a dramatic decline over the past ten years. A survey conducted by the Center for Conservation Biology on June 7th detected only 5 singing males, in stark contrast to an identical survey conducted in 2005 that resulted in the detection of 41 singing males. Discovery of the site in 2005 extended the known breeding range 90 kilometers to the south.

The coastal plain swamp sparrow is restricted to the mid-Atlantic coast. The form is distinctive in having a larger bill, grayer plumage, and more black in the crown and nape compared to other swamp sparrows. A recent assessment of the population within Maryland, Delaware, and New Jersey resulted in a conservative estimate of 28,000 pairs and established a center of abundance around Delaware Bay and the Tuckahoe and Mullica rivers in coastal New Jersey. The survey also suggested a decline in both abundance and distribution along the western shore and lower eastern shore of the Chesapeake Bay.

Within the Coastal Plain, swamp sparrows occur in marshes within a fairly narrow salinity band from tidal fresh to approximately one part per thousand. Pairs utilize habitats with a mix of marsh vegetation and shrubs that typically form along the marsh-upland interface. Within the Mulberry Point site, habitat components include olney threesquare (Scirpus olneyi) , salt meadow hay (Spartina patens) , marsh hibiscus (Hibiscus moscheutos) , and cattail (Typha augustifolia) .

The cause of the population decline is unclear. The preferred ecotone habitat has been visibly reduced over the decade with invasive common reed (Phragmites australis) occupying more of the adjacent uplands and the wetter portions of the marsh containing pickerelweed (Pontederia cordata)expanding. These two patterns have effectively squeezed the preferred breeding habitat within the site. It is also well known that occupation of sites by the form may be episodic. Populations seem to come and go over relatively short period
