Ecology of the Grizzly Bears of Yellowstone National Park

The Grizzly Bear is a subspecies of brown bear that once roamed large swaths of the mountains and prairies of the American West. The Greater Yellowstone Ecosystem and northwest Montana are the only areas south of Canada that still have large Grizzly Bear (Ursus arctos horribilis) populations. Steve Ropski will discuss eating habits, hibernation, reproduction, thermoregulation, status, and  attacks on humans by Grizzly Bears. He will also give a little history of Yellowstone National Park.
