DOI on the Landscape - Avian Population Response to Ecological Change along the Arctic Coastal Plain

US Geological Survey (USGS) - The Arctic Coastal Plain (ACP) region of Alaska contains the vast majority of the nation's arctic tundra ecosystems that exist for the most part in a pristine, but ecologically sensitive state. Some of the most common indicators of environmental change are changes in land form, which can affect the biophysical patterns and processes within both hydrologic and terrestrial systems. Arctic...

Population Status and Ecology of North Pacific Shorebirds

US Geological Survey (USGS) - Alaska is widely recognized as a global center for shorebirds. Ninety percent of the migratory species in the Western Hemisphere have breeding populations in Alaska. The North Pacific hosts one-third of the world's shorebird fauna. Coastal habitats are critical during some phase of their annual cycle, particularly during the nonbreeding period. Many coastal areas are being altered at an...

Changing Arctic Ecosystems: Enhancing forecasts of walrus population response to a rapidly changing Arctic ecosystem (Modeling walrus population dynamics and bioenergetics)

US Geological Survey (USGS) - The Pacific walrus is a benthic feeding, ice-associated pinniped that ranges over the continental shelves of the Bering and Chukchi seas. The extent of summer sea ice in the Chukchi Sea has decreased drastically in recent years and this trend is projected to continue. Changes in the distribution of seasonal sea ice will likely affect walrus distribution and behavior and could affect the status...

Shorebirds and Infaunal Abundance and Distribution on Delta Mudflats along the Beaufort Sea (AK-11-10a)

US Bureau of Ocean Energy Management (BOEM) - This study builds on an existing study with Fish and Wildlife Service (FWS) and tiers off a BOEMRE/CMI previous shorebird study by Abby Powell across the Beaufort and Chukchi Sea coasts. This study focuses intensively on a few sites along the coast of the FWS Arctic Refuge and two years data collection has been funded by FWS. The USGS/BOEMRE partnership would collect data on a few sites...

Seabirds, Forage Fish, and Marine Ecosystems Research

US Geological Survey (USGS) - The objective of this project is to observe the effects of human perturbation on seabird populations, and distinguish the effect of human input from natural variations that affect prey density, population distribution and population dynamics. The primary objective of this subtask is to measure and characterize the numerical and functional response of seabirds to variation in prey density,...

Pelagic Seabird Database for the North Pacific

US Geological Survey (USGS) - Much pelagic seabird data remains in individual datasets. While some investigators can analyze their own data sets for specific purposes, the bulk of pelagic seabird data are inaccessible to any one user group. We continue to combine all available data into a standardized database, and we are developing tools and products to map and interpret these data. This provides scientists, resource...

Status and Trends of Boreal Land Bird Populations

US Geological Survey (USGS) - Boreal habitats in Alaska support 130 species of breeding landbirds, including 68 species that migrate to Neotropical wintering areas. Significant population declines have been documented for many of these species in temperate regions over the past 30 years. Land managers in Alaska are currently faced with major decisions that will influence the functioning of entire ecosystems, including how...

Using Genetic Markers to Determine Population Status and Management Strategies of Migratory Birds, Terrestrial and Marine Mammals, and Plants

US Geological Survey (USGS) - Identifying genetic markers for various species in order to develop conservation strategies. Alaska provides critical breeding, molting and wintering habitat for migratory and resident birds, hosts numerous resident and migratory or nomadic populations of terrestrial and marine mammals, and provides habitat for several resident amphibian species. Populations of nomadic and resident mammals,...

Winter Ecology of Stellers Eiders and Other Seaducks in western Alaska

US Geological Survey (USGS) - Declines in the breeding population of Steller's eiders (STEI) in Alaska have resulted in its listing of as threatened under the provisions of the Endangered Species Act. Exposure to petroleum-based hydrocarbons from boating or fishing activities and accidental oil spills is cause for concern at wintering areas of STEI in Alaska. Thus, the wintering activity and habitat selection of STEI may...
