John M. Pearce, Ph.D.
I am the Program Manager for marine and terrestrial ecosystems research at the USGS Alaska Science Center. I also coordinate the USGS Changing Arctic Ecosystems Initiative and provide outreach to the public about our research. I have been a research biologist in Alaska for 25 plus years studying migratory birds, avian disease, and population genetics.

Q&A: The Role of USGS Ecosystems Science in Alaska
The USGS is the science arm of the Department of the Interior (DOI) with a mission to provide timely and impartial science information to decision-makers, industry, and others. Topics of USGS research and monitoring in Alaska include Ecosystems, Energy and Minerals, Geology, Water Resources, and Natural Hazards. At the Ecosystems Office of the USGS Alaska Science Center, research and monitoring...
High Priority Species for Avian Influenza in Alaska
In early 2006, an Alaska Interagency Avian Influenza Working Group was formed to develop a ranking matrix for selecting priority species to be sampled within Alaska. Most wild bird species with populations that utilize areas of both Alaska and Asia were identified and considered in the ranking exercise. Based on scoring criteria, 28 target species were chosen for sampling. Alaska is a...
Avian Influenza Research
Since 2006, the USGS Alaska Science Center has been part of the State and Federal interagency team for the detection and response to highly pathogenic (HPAI) viruses in North America. Avian influenza or "bird flu" is a viral disease that primarily infects domestic poultry and wild birds. Avian influenza viruses are naturally occurring in wild birds such as ducks, geese, swans, and gulls. These...
Swan Research
USGS research on swans in Alaska has focused on pathogens, contaminants, and demographic rates in each of the different breeding areas of Alaska. The vastly different migration patterns of swans in Alaska means that there are multiple factors on the wintering grounds and during migration that may influence population size and trends.
Dabbling and Diving Duck Research
Dabbling and diving ducks, such as mallards, pintails and scaup, are widespread species throughout North America. Additionally, their migratory flyways pass through Asia and North America overlap in Alaska. Population trends of these species are closely tracked through aerial surveys by management agencies. Results from these and other surveys are then used to formulate management actions to...
Sea Duck Research
USGS research on sea ducks is designed to anticipate and address priority information needs of management agencies. Additionally, work is focused on individual species biology, migration and population status and trends because until recently, very little was known about sea ducks in Alaska.
