Resumé

Tissue-samples from 161 bank votes (Clethrionomys glareolus) collected in three forests (five sampling Localities) situated in eastern Jutland (Denmark) were analysed by nine microsatellite loci. The genetic diversity found within the populations was high (H-e=0.753-0.806). Bank votes have specific habitat requirements favouring woodlots, hedgerows and deciduous forests as their prime living area. Hence, a natural or human-induced fragmentation of the forest may cause a sub-structuring of the populations and thereby a restriction of dispersal among populations. The sub-structuring indicated by the observed significant genetic differentiation among the five geographically distinct Localities (F-st=0.033, P <0.05) could either result from habitat fragmentation or a combination of home range behaviour and different tree composition in the forests. A road situated between two adjacent forests was not found to exert any harder effect to the gene flow of bank votes. In one out of five Localities investigated, genetic evidence for a recent bottleneck-like situation was found. Bank votes are known to exhibit sometimes huge density fluctuations not only from year to year but also from season to season. The bottleneck-like situation found could therefore be due to the Low number of individuals during the Low-density phase. (c) 2005 Deutsche Gesellschaft fur Saugetierkunde.
