		Ursus is Latin for bear and arctos is Greek for bear (5).
		Ursus arctos includes four main subspecies: Ursus arctos horriblis (Grizzly Bear), Ursus arctos middendorffi (Brown Bears of the Alaskan Islands of Afrogak, Shoyak, and Kodiak), and Ursus arctos arctos (European Brown Bear), and Ursus arctos yesoensis (Japanese Brown Bear).
		Ursus arctos tends to migrate to the mountains in the summertime to stay cool in its environment, and captivity might not be able to provide the diverse habitat requirements (9).

		The one found in New England is the first-described or “nominate” subspecies, Ursus americanus americanus.
		Black bears are typically fl overall, with brown muzzles, perhaps brown spots over the eyes, and sometimes a white V or patch on the chest.
		However, one of the named subspecies of fl bear is the so-called “cinnamon” bear (Ursus americanus cinnamonum) described in 1854 by J.J. Audubon and J. Bachman from a specimen taken in Colorado.

		Abstract: We estimated survival and reproduction rates of brown bears (Ursus arctos) on the coast of Katmai National Park, Alaska, during 1989–95 to assess effects of the 1989 Exxon Valdez oil spill.
		We examined hunter ranking of wildlife species and suggest that while hunters still remain negative to brown bears (Ursus arctos) and lynx (Lynx lynx), there are differences between those who live in provinces with a longer tradition of living with bears and lynx and those who have had little exposure to these large carnivores.
		Most respondents who said they had previously reported damage to a management agency were satisfied with the help that they received, even though agency assistance was generally limited to finding a hunter to kill the bears or to a discussion about bear ecology and the inefficacies of dealing with crop damage.
