GRIZZLY BEAR HABITAT SELECTION IS SCALE DEPENDENT

Ecological Applications, 2007
The purpose of our study is to show how ecologists' interpretation of habitat selection by grizzly bears (Ursus arctos) is altered by the scale of observation and also how management questions would be best addressed using predetermined scales of analysis.

Constraints on herbivory by grizzly bears

Oecologia, 2001
Although well known as carnivores and not capable of digesting plant fiber, grizzly bears (Ursus arctos horribilis) consume over 200 species of plants and are entirely vegetarian in some ecosystems. Even in ecosystems with abundant meat resources, green vegetation can be an important seasonal food resource.

Hypothyroidism in a Grizzly Bear

Journal of the American Veterinary Medical Association, 1970
SUMMARY Dermatitis associated with hypothyroidism occurred in a captive grizzly bear. The diagnosis was confirmed at necropsy. It was believed that the hypothyroid condition in this case resulted from a combination of management factors, including low amounts of dietary iodine and the feeding of goitrogenic materials.

Demography of the Yellowstone Grizzly Bears

Ecology, 1999
We undertook a demographic analysis of the Yellowstone grizzly bears (Ursus arctos) to identify critical environmental factors controlling grizzly bear vital rates, and thereby to help evaluate the effectiveness of past management and to identify future conservation issues.
