Constraints on herbivory by grizzly bears
Oecologia, 2001Although 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, 1970SUMMARY 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, 1999We 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.

Demography of the Yellowstone Grizzly Bears: Comment
Ecology, 2000This analysis of demography of the Yellowstone grizzlies by Pease and Mattson (1999) (hereafter referred to as "P&M") evidently resulted from a dedicated and extensive effort by the authors. An interesting model was developed that may provide the basis for useful further analyses.

GRIZZLY BEAR HABITAT SELECTION IS SCALE DEPENDENT
Ecological Applications, 2007The 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.

Conservation of the Yellowstone Grizzly Bear
Conservation Biology, 1991Abstract: We review literature relevant to the conservation of Yellowstone's grizzly hear population and appraise the bear's long‐term viability. We conclude that the population is isolated and vulnerable to epidemic perturbation and that the carrying capacity of the habitat is likely to shift downward under ...

Natal dispersal of grizzly bears
Canadian Journal of Zoology, 2001We studied natal dispersal of grizzly bears (Ursus arctos), a solitary nonterritorial carnivore with a promiscuous mating system, between 1979 and 1998. Dispersal distances for 2-year-olds did not differ between males and females, but by 3 years of age, males had dispersed farther than females, and farther still by 4 years of age.
