Alaska Science Center
Home
Our Alaska Science Center priority is to continue the important work of the Department of the Interior and the USGS, while also maintaining the health and safety of our employees and community. Based on guidance from the White House, the CDC, and state and local authorities, we are shifting our operations to a virtual mode and have minimal staffing within our offices. If you need additional assistance, please contact Chris Zimmerman.

USGS Responds to Spring Flooding
U.S. Geological Survey field crews are measuring flooding across the country as spring weather is in full swing. Warming temperatures, increased precipitation and snowmelt have caused moderate to major flooding in the upper Midwest, East Coast, Central Plains and the Southeast portions of the country.
Movements and Habitat Use of Loons for Assessment of Conservation Buffer Zones in the Arctic Coastal Plain of Northern Alaska
Few data exist to assess the value of National Petroleum Reserve-Alaska management buffer zones for conservation-reliant yellow-billed loons or sympatrically breeding red-throated and Pacific loons.
The Other 364 Days of the Year: The Real Lives of Wild Reindeer
Caribou, North America’s wild reindeer, have lives apart from their famous role on Christmas Eve. To learn more about how these Arctic antler-bearers spend the other 364 days of the year, we talked to USGS caribou expert Dr. Layne Adams, who has studied these animals for more than 35 years.

After-hatch and hatch year Buff-breasted Sandpipers (Calidris subruficollis) can be sexed accurately using morphometric measures
Determining the sex of birds quickly in the field can help in studies of behavior and distribution, and when selecting particular sexes for deploying tracking devices or collecting samples. However, discerning males from females is difficult in species that are plumage monomorphic and have overlapping sexual-size dimorphism, as in Buff-breasted...
Almeida, Juliana B.; Lopes, Iara F.; Oring, Lewis; Tibbitts, Lee; Pajot, Lisa M.; Lanctot, Richard B. Mitochondrial genome diversity and population mitogenomics of Polar cod (Boreogadus saida) and Arctic dwelling gadoids
High-latitude fish typically exhibit a narrow thermal tolerance window, which may pose challenges when coping with temperatures that shift outside of a species’ range of tolerance. Due to its role in aerobic metabolism and energy balance, the mitochondrial genome is likely critical for the acclimation and adaptation to differing temperature...

Sample-size considerations for a study of shorebird nest survival in the 1002 Area, Arctic National Wildlife Refuge, Alaska
Authorization of lease sales for oil development in the 1002 Area of the Arctic National Wildlife Refuge has highlighted gaps in information about biological communities in the area. The U.S. Fish and Wildlife Service, which is planning a study to evaluate spatial variation in the nest survival of tundra-breeding shorebirds to identify hotspots...
