Analysis of multi-annual data on the population dynamics of the bank vole in many regions of the former Soviet Union enabled us to distinguish six "zones of similar population dynamics" within that territory. The data employed were obtained mostly by the trap-line method that has been widely used by local ecologists. The largest and most stable density of the bank vole populations has been found in forests with broad-leaved tree species, particularly linden. The influence of various factors on the fluctuations in numbers in different districts is discussed.

Acoustic communication probably only reflects the emotional state of the vole without information transmitting.
