Daily movements of brown bears (Ursus arctos) in the middle Sikhote-Alin

Seryodkin I. V.  (PhD, Leading Researcher, Pacific Geographical Institute FEB RAS (Vladivostok))

The daily movements of 12 adult males, seven adult females, and one young male of brown bears (Ursus arctos) were assessed using radio- and GPS telemetry in the Middle Sikhote Alin in 1993–2011. The average daily linear distance of adult males was 3.13 km, adult females — 1.65 km, and young male — 2.12 km. The daily distance of males was significantly greater than that of females. In females, the rate of daily movements was more in summer than in spring and autumn. Two types of movements were distinguished: insignificant with feeding and transitions up to 19 km per day. Significant movements of bears were more typical for males, were observed in all seasons, and were associated with feeding behavior.

Keywords:daily linear distance, radiocollars, Sikhote-Alin Reserve, space use, telemetry
