The goal of this research was to describe the ecology of black bears in the Yosemite Valley (YV) region of Yosemite National Park with respect to human activity and valley infrastructure. This research effort was designed to contribute to a broad, interdisciplinary effort aimed at reducing human-...
Asiatic black bears have a coat of black fur (occasionally brown or even blonde, depending on the subspecies), a characteristic whitish v-shaped marking on their chest, and a ruff of longer hair around their necks, which is supposed to help them look bigger than they are. Asiatic black bea...

In the defoliated region of Virginia, 138 ± 12 bears/yr and 220 ± 12 bears/yr were harvested before (1980-1986) and during infestation, respectively (P = 0.03). In addition, proportion of females harvested in this region increased from 34% to 40% (P = 0.09). These increases may ...
American black bears(Ursus americanus) live in North America and Mexico; their diet consists primarily of leaves, buds, shoots, berries, and nuts. Subspecies of this bear include the cinnamon bear, the glacier bear, the Mexican black bear, the Kermode bear, the Louisiana black bear, and sever...
