Linda J. Gormezano and Robert F. Rockwell What to eat now? Shifts in polar bear diet during the ice-free season in western Hudson Bay Ecology and Evolution 3
We analyzed scat contents to characterize the current terrestrial polar bear diet in western Hudson Bay and compared our results to a similar study done in the 1960s to see how the diet has changed since the onset of climate-related changes. We found that polar bears are eating new foods (eggs, caribou) in relative proportion to their availability on the landscape. We discuss whether the diet shift is solely a response to nutritional stress or is another expression of plastic foraging strategy typical of other Ursids.
