Marking activity of common beaver (Castor fiber L.) in the settlements of channel type. Dynamic aspect.

摘要

Features of the marking activity of beavers in the channel-type settlements are considered. On the basis of statistical data it was determined that the signal hillocks may be recommended for investigation of dynamic indexes of scent marking by beavers. On the basis of quantitative methods the role of the level mode of water streams in the appearance of olfactory marks is demonstrated; as a result, the inversely proportional dependence between these parameters has been revealed.Notes Translated from Sibirskii Ekologicheskii Zhurnal (2012) 19 (1) 165-171 (Ru).
