Abstract
We studied brown bear ( Ursus arctos ) land use using satellite collars deployed on four animals in Kamchatka in 2005-2006 and three animals on Sakhalin Island in 2011-2012. The annual home range sizes ranged from 6.09 to 27.58 km2 for females and was 153.12 km2 for male. The sizes of annual core area of home range did not exceed 1.68 km2. Seasonal home range sizes were the highest in August and September and the lowest in May. Home ranges of two females in Kamchatka significantly overlapped, while a lower degree of overlap was found for two females in Sakhalin. Habitat use by bears depends on the seasonal distribution of food, in particular salmon.
