Abstract

Locations of dens with respect to space use, pre- and post-denning movements of brown bears in the Russian Far East

Highlights

In the Russian Far East, Ursus arctos Linnaeus, 1758 plays a considerable role in ecosystems and is of great practical importance for humans (Revenko, 1993; Yudin, 1993)
Analysis of data based on the den location in relation to the used space have shown that brown bears, especially males, tend to choose den locations at some distance from places used during the non-denning period in the Russian Far East
This is explained by the fact that brown bears have special requirements for selecting dens, which may not correspond to the area used in the most parts of their home ranges

Summary

Introduction

In the Russian Far East, Ursus arctos Linnaeus, 1758 (hereafter – brown bear, or bear) plays a considerable role in ecosystems and is of great practical importance for humans (Revenko, 1993; Yudin, 1993). The brown bear populations in this region are relatively prosperous. They need competent management to ensure their preservation. Brown bears spend a considerable part of their life in dens, an average of 146 days, in the Sikhote-Alin region (Seryodkin et al, 2003), while in the north of the Russian Far East it is up to 210 days (Chernyavskiy et al, 1993). Knowledge of the specifics of space use by animals and the ecology of the denning period is important for the development of a plan for the conservation and rational use of the brown bear
