The influence of sulfur and hair growth on stable isotope diet estimates for grizzly bears.

The influence of sulfur and hair growth on stable isotope diet estimates for grizzly bears.

Stable isotope ratios of grizzly bear (Ursus arctos) guard hair collected from bears on the lower Stikine River, British Columbia (BC) were analyzed to: 1) test whether measuring δ34S values improved the precision of the salmon (Oncorhynchus spp.) diet fraction estimate relative to δ15N as is conven...
