Dietary niche relationships among cervids relative to winter snowpack in northwestern Montana
We compared diets of white-tailed deer (Odocoileus virginianus ochrourus), Rocky Mountain elk (Cervus elaphus nelsoni), and Shiras moose (Alces alces shirasi) during two winters in the North Fork of the Flathead Valley, Montana. Diets of white-tailed deer contained the greatest proportions of low-ly...
