Population dynamics of forest voles (Clethrionomys, Rodentia) in northern European Russia

Abstract

Long-term data sets on the population dynamics of forest voles in northern European Russia were analyzed. Eastward and northward trends in changes of the ratio between model species and the degree of their dominance were revealed. In virtually all sites studied, the numbers of the northern red-backed and bank voles changed synchronously; however, the population dynamics became less synchronous as the distance between study areas increased.
