Description :
This paper presents stable carbon and nitrogen isotope data obtained from the fossil bone collagen of late Pleistocene short-faced bears and brown bears, and bone collagen from modern brown bears in eastern Beringia. The data elucidate many important aspects of these bears'diets and can be used to test the potential for competive interactions. The A. also summarizes a model of short-faced bear foraging behavior that is the most parsimonious integration of the isotope data and the morphological features.
