Age and Sex Composition of Seals Killed by Polar Bears in the Eastern Beaufort Sea

BACKGROUND: Polar bears (Ursus maritimus) of the Beaufort Sea enter hyperphagia in spring and gain fat reserves to survive periods of low prey availability. We collected information on seals killed by polar bears (n = 650) and hunting attempts on ringed seal (Pusa hispida) lairs (n = 1396) observed...
