Abstract
Abstract. In the northern U.S. Rockies, including the Greater Yellowstone Ecosystem (GYE), connectivity is a concern because large carnivores have difficulties dispersing successfully between protected areas. One area of high conservation value because of its importance for connecting the GYE to wilderness areas of central Idaho is the Centennial Mountains and surrounding valleys (2500 km2) along the Idaho—Montana border just west of Yellowstone National Park. The current expansion of grizzly bears (Ursus arctos) and other large carnivore populations outside protected areas of Yellowstone National Park and Grand Teton National Park has placed a greater emphasis on potential linkage zones in the northern Rockies. Here we use black bears (Ursus americanus) as a test case to demonstrate the utility of using detection dogs and DNA analysis coupled with resource selection probability function (RSPF) models to examine habitat suitability for large carnivores in critical linkage zones. Detection dogs specificall...
