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.
Changes in aquatic ecosystems, like those of the black duck on the Delmarva peninsula, can influence the dynamics of the relationship between a pathogen like avian flu and its host.More info

Mapping the relationships between trail conditions and experiential elements of long-distance hiking
Trail users that experience acceptable social and ecological conditions are more likely to act as trail stewards, exhibit proper trail etiquette, and use low-impact practices. However, the relationships between specific trail conditions and experiential elements of long-distance hiking are not well understood. Therefore, the purpose of this study...Peterson, Brian A.; Brownlee, Matthew T.J.; Marion, Jeffrey L.
Modelling sound attenuation in heterogeneous environments for improved bioacoustic sampling of wildlife populations
Acoustic sampling methods are becoming increasingly important in biological monitoring. Sound attenuation is one of the most important dynamics affecting the utility of acoustic data as it directly affects the probability of detection of individuals by acoustic sensor arrays and especially the localization of acoustic signals necessary in...Royle, J.

Monitoring responses to variation in food supply for a migratory waterfowl: American Black Duck (Anas rubripes) in winter
Wintering Black Ducks (Anas rubripes) concentrate in wetlands along the Atlantic coast where natural and anthropogenic disturbances have increased over the last 50 years, a period in which the population of Black Ducks has declined. We studied the sensitivity of Black Ducks to perturbations in food supply that often result from disturbances by...Barboza, Perry S.; Jorde, Dennis G.
