Amanda with vultureAmanda Holland is a Masters student in the Warnell School of Forestry and Natural Resources at the University of Georgia. Her research interests are relatively broad and include avian ecology, landscape ecology, scavenger ecology, ecotoxicology, and management of at-risk, threatened, and endangered species. She specialized in avian ecology and conservation while earning a B.S. in Fisheries and Wildlife Science at Oregon State University where she was involved in research on California Condors. Her current research is focused on the spatial ecology of black and turkey vultures in the southeastern United States and is using GPS transmitters to elucidate fine-scale movement and resource selection patterns for these species. When not spending time studying her favorite group of animals (vultures!), she enjoys birding, road trips, and brewing beer at home.

DaveDave Keiter is a Masters student in the Warnell School of Forestry and Natural Resources at the University of Georgia. His thesis research will compare methods of estimating feral swine population size with indices of relative abundance to determine the most cost-effective manner of monitoring this invasive species. He graduated in 2013 from the SUNY College of Environmental Science and Forestry (SUNY-ESF) with a B.S. in Wildlife Science. At SUNY-ESF he conducted research on small mammals in Alaska and Russia for his honors thesis, and has since been involved with projects studying the nutritional ecology of black-tailed deer in Washington State and population dynamics northern bobwhite quail in Texas. His research interests focus on the population dynamics and ecological interactions of invasive and reintroduced species. In his spare time, he enjoys backpacking, birding, brewing, and board games.

Ricki with red-ruffed lemursRicki Oldenkamp is a Masters student in the Warnell School of Forestry and Natural Resources at the University of Georgia. As an undergraduate student, Ricki worked on a diverse array of research projects while earning her B.S. in Biology at Northern Michigan University. These studies included work on the transmission of botulism to birds through an invasive fish species in Lake Michigan, behavioral observations of orangutans in Borneo, cognitive testing of Marine bomb and narcotics detection dogs, and the hormonal link between the brain and stomach for obesity in a mouse model. Through this undergraduate research Ricki published a paper on using a novel technique to estimate the amount of herbivory ants prevent on emerging Bracken fern fiddleheads and is a co-author on a cognitive study of how group size affects social cognition in lemurs. At UGA her research will focus on the effects of anthropogenic stressors on wildlife health. Specifically, she will evaluate contaminant burdens in game species and quantify risk to hunters from consuming contaminated wildlife. When not immersed in research she rock climbs, ice climbs (back in Michigan!), and loves to long distance backpack.

AnsleyAnsley Silva graduated from the Warnell School of Forestry and Natural Resources at the University of Georgia in 2009. Much of her time as an undergraduate was spent as an exchange student at the Universidade Federal de Viçosa, Brazil. During that time she researched some of the impacts of hydropower dams in the Doce River Basin of Minas Gerais. Now as a Masters student under Dr. Jim Beasley and Dr. Kamal Gandhi in Warnell, Ansley's current research focuses on the effects that water and soil contamination have on the invertebrate decomposer community, and whether diversity of this community changes as a function of distance to contamination sites or proximity to riparian habitat. Her interests revolve around anthropogenic influences on the environment. Outside of research, she spends her time backpacking and teaching yoga.

ChrisChris Leaphart graduated from the University of South Carolina-Aiken in May 2014 with a B.S. in Biology. While at USCA, Chris spent the majority of his time working in Dr. Derek Zelmer’s parasitology lab, where he researched the effects of Haematoloechus infection on the functional response of libellulid odonate naiads, as well as other studies using digenean parasites. Currently he is conducting research at SREL under Dr. Jim Beasley and Bobby Kennamer, where he is examining the natural attenuation of radiocesium (137Cs) levels in whole-body counts of American coots (Fulica americana) collected from the Pond B reservoir at the Savannah River Site, as well as parasite burdens in wildlife inhabiting contaminated environments. His research interests include parasitology and the ecology and management of various wildlife and avian species. Chris plans to obtain a Master’s Degree (and eventually a Ph.D.) to conduct research that investigates the effects of parasitism on different hosts, and how host-parasite interactions can have broader influences on ecosystem function.

Kevin with i'iwiHailing from Rochester, New York, Kevin Eckert graduated from SUNY-ESF in 2012 with a B.S. in Wildlife Science.

Mike with sharkMike Byrne joined the Beasley lab as a postdoc in 2014 where he is involved in a number of studies including research on the spatial ecology of gray wolves at Chernobyl, use of fine-scale spatial data to elucidate movement behavior of vultures, and the ecology and management of feral swine. Mike received a BS in Biology from Worcester State College in 2003, a MS in Biological Sciences from the University of Rhode Island in 2007, and a Ph.D. in Wildlife and Fisheries Sciences from Louisiana State University 2011. After completing his Ph.D. Mike worked as a postdoc under Dr. Mike Chamberlain in the Warnell School of Forestry and Natural Resources at the University of Georgia from 2012-2014 before joining the Beasley lab. Mike’s research interests include behavioral ecology, animal movement ecology, wildlife habitat use and selection, and population ecology. He is particularly interested in understanding how the behavior of individuals gives rise to, and is itself influenced by, larger population and landscape-level processes of species distribution and evolution. Much of his research involves the use of telemetry to gather data on individuals, and he has a keen interest in the study of animal movement (both long and short term), as it naturally weaves together the above-mentioned research areas. He primarily works on vertebrate species in a variety of terrestrial and marine environments; from forests to open-ocean pelagic ecosystems.

Josh with sedated cougarJosh Smith is a postdoc in the Beasley lab where his primary focus is on research into indirect transfer of toxicants to non-target organisms through scavenging pathways on Guam. Josh received his BS in Biology from East Tennessee State University in 2000, a MS in Wildlife and Fisheries Sciences from South Dakota State University in 2007, and a PhD in Wildlife and Fisheries Sciences from South Dakota State University in 2014. His research interests broadly lie in understanding population dynamics and how changes in spatial, temporal, biological and environmental processes influence their fluctuations. Much of his previous research has focused on carnivore ecology, the influence of landscape characteristics on species distribution, estimating population level vital rates (primarily size and survival), mark-recapture analysis, anthropogenic influences on species habitat selection, scavenging ecology, and the influence of predation and disease as a regulatory mechanism on prey populations.
