[The factors influencing the sound activity of forest voles].

Abstract

The article is devoted to the effect of context on the acoustic activity of bank voles of 4 species (Clethrionomys glareolus, C. centralis, C. rutilus, and C. rufocanus) living in experimental groups. In addition to species differences and social state of a specimen in the group, the acoustic activities of vole is affected by such factors as locomotor activity of the vole itself and its partners (especially dominant ones) and aggression of surrounding voles.
