Patuxent Wildlife Research Center
Patuxent Wildlife Research Center (PWRC) produces innovative science to support natural resource management and meet our nation’s most pressing conservation challenges.
PWRC research topics include bird population dynamics, ecotoxicology, and the development of quantitative & decision analysis tools. We conduct several national programs, including the Bird Banding Lab and the Breeding Bird Survey.
USGS Patuxent scientists are providing managers with tools for improving detection and for proactively mitigating the impacts of amphibian diseases.More info
If you enjoy finding tadpoles in ponds, you already know frogs are sensitive to water conditions in some way. This new study explores that sensitivity, asking how amphibians across North America are responding to altered climatic conditions.Read Publication

Description of disparate responses of two indoor feral bee colonies
As is sometimes the case, field research does not always go according to plan. This is especially true when the research involves free-ranging animals. We recently conducted a preliminary field study that involved placing a beehive in a tent and individually releasing marked honey bees (Apis mellifera) outdoors to study their ability to locate...Vyas, Nimish B.; Plunkett, Amanda D.
A vision for documenting and sharing knowledge in conservation
As editors, we mark the launch of Conservation Science and Practice, a journal of the Society for Conservation Biology (SCB), with the following remarks framing the purpose and aspirations of the journal. Our aim is to share scholarship on and experiences of the practice of conservation. We define conservation practice as the application of...Schwartz, Mark W.; Belhabib, Dyhia; Biggs, Duan; Cook, Carly N.; Fitzsimmons, James; Giordano, Anthony J.; Glew, Louise; Gottlieb, Sara; Kattan, Gustavo; Knight, Andrew T.; Lundquist, Carolyn J.; Lynam, Antony J.; Masuda, Yuta J.; Mwampamba, Tuyeni H.; Nuno, Ana; Plumptre, Andrew J.; Ray, Justina C.; Reddy, Sheila M.; Runge, Michael C.
The missing dead: The lost role of animal remains in nutrient cycling in North American Rivers
While leaf litter, wood, and other plant remnants are known to play a central role in lotic ecosystems, animal remains (carcasses, bones, shells) have received less attention. We propose a simple classification scheme for animal remains in rivers based on origin (authochthonous vs. allochthonous) and frequency (pulsed vs continuous). We then...Wengerd, Seth J.; Subalusky, Amanda L.; Freeman, Mary C.
