Spatial and temporal variation in the diets of polar bears across the Canadian Arctic: indicators of changes in prey populations and environment / S.J. Iverson, I. Stirling, S.L.C. Lang.

Title: Spatial and temporal variation in the diets of polar bears across the Canadian Arctic: indicators of changes in prey populations and environment / S.J. Iverson, I. Stirling, S.L.C. Lang.
Author(s): Iverson, S. J.

Publisher: Cambridge: Cambridge University Press
In: Top predators in marine ecosystems : their role in monitoring and management. (2006.),
Abstract: Reports use of quantitative fatty acid signature analysis of polar bear (Ursus maritimus) adipose tissue to estimate diets in 1980s/1990s across three major regions of Canadian Arctic (Davis Strait, western Hudson Bay and Beaufort Sea). Finds that, although polar bears consumed ringed (Phoca hispida) and bearded (Erignathus barbatus) seals throughout range, diets differed greatly among regions. Results provide new insight into foraging ecology of polar bears across their Canadian range.
