Causes and consequences of sexual habitat segregation in grizzly bears ...
I studied habitat use and population dynamics of 2 grizzly bear (Ursus arctos) populations to test 3 competing hypotheses of sexual habitat segregation (no avoidance, food competition, and sex competition) and 3competing hypotheses on the effects of adult male mortality on female reproduction (addit...
