Importance of Eelgrass Beds at Izembek National Wildlife Refuge for Overwintering Migratory Waterfowl
Our analysis of migratory connectivity between Arctic and subarctic brant provided new insights into recent changes in their winter distribution and the implications of those changes for individual reproductive success and population dynamics of brant in Alaska.
Exposure of Wild Mammals to Influenza A(H5N1) Virus, Alaska, USA, 2020–2023
Samples from wild mammals in Alaska showed that 4 species, including bears and foxes, were exposed to highly pathogenic avian influenza viruses.
Environmental Occurrence of Avian Influenza Virus Relative to Bait Trapping of Waterfowl
New study finds that bait trapping was associated with localized increases in avian influenza virus.
Habitats of Historic and Contemporary Sea Otters for Managing Future Status and Trends
Historic and contemporary data provide forecasts of future sea otter habitats in areas of otter recolonization and potential reintroduction.
Photogrammetry to Monitor Walrus Body Condition and Calf Growth
Innovative drone technology provides critical insights into the body condition and health of Pacific walruses in a changing Arctic.
Assessing the Sustainability of Pacific Walrus Harvest
The Pacific walrus is a critical subsistence resource for many Alaska Native communities in western and northern Alaska but is subject to rapid habitat loss due to diminishing sea ice and an increasing anthropogenic footprint in the Arctic.
