Zoology
Brown bears dominate gray wolves, cougars, black bears, and even polar bears. It is suggested that care of black bear cubs and hence reproductive success for black bears is tied to the forest biome, and that the grizzly/brown bear in branching out from the forest onto non-treed areas such as tundra, grasslands and prairie edges, gained rich new food sources, but also became more aggressive than the black bear, a behavioural adaptation to cub care in this new habitat.
