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.
