✦ Synopsis
The effects of interaction among individuals with respect to wheelrunning activity has been investigated in two geographically separated populations of the field vole Microtus agrestis L. In one of them, a northern cyclically varying population, a strictly nocturnal activity pattern is changed into a more or less short term 24 h pattern under conditions of increased contact among individuals. In the other population, south-Swedish, without population cycles, no such effects were observed. This indicates population differences in response to interindividual contact which might be of importance to the known differences in population dynamics.
