Organohalogen concentrations in blood and adipose tissue of Southern Beaufort Sea polar bears
151 organohalogen chemicals (OHCs) in whole blood and subcutaneous fat of 57 polar bears sampled along the Alaskan Beaufort Sea coast in spring, 2003 were analyzed for major... -
Genetic Variation, Relatedness, and Effective Population Size of Polar Bears (Ursus maritimus) in the southern Beaufort Sea, Alaska
Polar bears (Ursus maritimus) are unique among bears in that they are adapted to the Arctic sea ice environment. Genetic data are useful for understanding their evolution and... -
Reduction of Garbage in the Diet of Nonbreeding Glaucous Gulls Corresponding to a Change in Waste Management
Glaucous gulls (Larus hyperboreus) are major predators in the Arctic and may benefit from human development. We studied use of garbage by glaucous gulls in Barrow, Alaska, in... -
Dietary biomagnification of organochlorine contaminants in Alaskan polar bears
The variation in PCB153 and oxychlordane concentration are strong indicators of variation in diet and biomagnification of organochlorines among polar bears related to their sex,... -
