Movements of polar bear females (Ursus maritimus) during an ice-free period in the fall of 2011 on Alexandra Land Island (Franz Josef Land Archipelago) using satellite telemetry

摘要

The behavior of female polar bears with cubs in an isolated terrestrial area of Alexandra Land Island (Franz Josef Land Archipelago) was analyzed in the fall of 2011 in an ice-free period using Argos satellite telemetry and the data of ground observations. The size and structure of their home ranges and selection of their habitats have been estimated; the differences in behavior of tagged animals have been analyzed.
