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
Undergraduate students with Smithsonian-Mason School of Conservation take a field trip the BBL’s fall migration monitoring station, to learn about bird banding in the field first hand.
Over 5,000 people provided feedback about Reportband.gov as part of an online survey conducted by the University of Baltimore.
Identifying management-relevant research priorities for responding to disease-associated amphibian declines
A research priority can be defined as a knowledge gap that, if resolved, identifies the optimal course of conservation action. We (a group of geographically distributed and multidisciplinary research scientists) used tools from nominal group theory and decision analysis to collaboratively identify and prioritize information...Campbell Grant, Evan H.; Adams, Michael J.; Fisher, Robert N.; Grear, Daniel A.; Halstead, Brian J.; Hossack, Blake R.; Muths, Erin L.; Richgels, Katherine L.

Investigating home range, movement pattern, and habitat selection of Bar-headed Geese during breeding season at Qinghai Lake, China
The Bar-headed Goose is an important species in Asia, both culturally and ecologically. While prior studies have shown Qinghai Lake supports one of the largest breeding areas for Bar-headed Geese, little is known regarding the species movement ecology during the breeding season. In this study, we examined Bar-headed Goose home range size within...Zheng, Ruobing; Smith, Lacy M.; Prosser, Diann J.; Takekawa, John Y.; Newman, Scott H.; Sullivan, Jeffery D.; Luo, Ze; Yan, Baoping
Multidirectional abundance shifts among North American birds and the relative influence of multifaceted climate factors
Shifts in species distributions are major fingerprint of climate change. Examining changes in species abundance structures at a continental scale enables robust evaluation of climate change influences, but few studies have conducted these evaluations due to limited data and methodological constraints. In this study, we estimate temporal changes in...Huang, Qiongyu; Sauer, John R.; Dubayah, Ralph O.
