Unified Interior Regions

Alaska

The Alaska Region represents a resource-rich, dynamic landscape shaped by volcanos, earthquakes, major rivers, and glaciers. Here, we conduct research to inform management of Alaska’s extensive natural resources, inform national Arctic energy policy, and provide scientific information to help others understand, respond to, and mitigate impacts from natural hazards.

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...

Seabirds and Forage Fish Ecology

Alaska's coastal and offshore waters provide foraging habitat for an estimated 100 million birds comprising more than 90 different species; from loons and seaducks that nest inland, to petrels and puffins that breed on islands off shore. All these birds depend on the sea to provide a wide variety of food types— from clams, crabs and urchins nearshore— to krill, forage fish, and squid offshore...

Ecosystem Shifts in Arctic Seas

In addition to the direct effects of sea ice loss on walrus (Odobenus rosmarus divergens) and polar bears (Ursus maritimus) that use ice as a platform, the decline of Arctic sea ice is predicted to promote a fundamental ecosystem shift from benthic animals that forage on the sea floor to pelagic animals that forage near the sea surface.
