Fluctuation patterns of bank vole populations were reviewed for central and north-western Europe. Many fairly stable populations occur in central and western Europe while clearly cyclic populations, with an interval of 3-4 year between peaks, are typical for northern Fennoscandia. There is a transition zone around 60 stopni N. In forests in central Europe dominated by oak, and less so by beech and lime, bank vole populations demonstrate outbreak dynamics with peaks at 6-9 year intervals, related to mast seeding. Both cyclic and outbreak populations show pronounced annual variations in reproduction and survival. Community conditions are described for these types of populations and annual variations in food supply are denoted. Isolated (island) populations are characterised by generally high densities and high adult survival. Factors that have been suggested to explain the various dynamics differ: predation and food for cyclic performance, food alone for outbreaks and social factors within circumscribed populations.

The bank vole in Europe is hardly genetically differentiated, except in northern Fennoscandia, but shows large phenotypic variation. Body weight has been studied in the field and in the laboratory. Large bank voles are known in northern cyclic populations found on islands and in alpine areas. Reproductive patterns show that the length of the breeding season and the maturation processes may be more influenced by the fluctuation patterns than the length of the vegetative period. Behavioural differences are also known to occur between individuals from northern cyclic populations and individuals from southern stable populations. The relative importance of density fluctuations patterns and environmental harshness in causing geographical variation patterns is not known.
