Abstract
Daily activity patterns of brown bears were monitored using radiotelemetry from 1993 to 2006, in the Sikhote-Alin Biosphere Reserve and adjacent areas. Outside of the denning period, bears were active for approximately 52% of the 24-hour period. Males were more active (64% of total time) than females (51%). Brown bears in the Sikhote-Alin are diurnal and crepuscular, but switch to a nocturnal pattern in areas of high anthropogenic influence. During the summer months, daily activity patterns were influenced by precipitation, cloud cover, and air temperature. © 2013 Pleiades Publishing, Ltd.
