Waterbirds
Patuxent has a long history of research activities supporting the management and conservation of waterbird populations. Current research interests include studying the movements and migration ecology of sea ducks and other waterbirds along the Atlantic Coast, a long-term demographic study of Roseate Tern populations, and the use of restored island habitats by nesting terns. Patuxent scientists...
American Black Duck and Threat of Avian Influenza
The Challenge: The genomic revolution is giving wildlife biologists new tools to assess the role of wildlife in spreading diseases that affect human populations. Peptide arrays are a high throughput technology that gives unprecedented breadth and depth of information about the immune system. We are using peptide arrays to assess the immune responses of Chesapeake Bay waterfowl to avian influenza...
Disease Resistance of Wildlife Species: how the immune system evolves and adapts
The Challenge: In an era when emerging infectious diseases are steadily increasing, human populations are exposed to virulent new pathogens. Insight into the human system can be gained from understanding the variety of immune adaptations of wildlife species. The vertebrate immune system is not static. Rather, it involves in response to the environment.
An Eco-immunological Study of Chesapeake Bay Waterfowl
The Challenge: The health of the abundant waterfowl species of Chesapeake Bay has become a major concern due to the spread of Avian Influenza (AI) across North America and the role of waterfowl as a vector of AI. For decades, the health of the Bay’s waterfowl has been affected by the degradation of water quality and food supply due to industrial contaminants,agricultural run-off, pollution from...
