Search for: [Description = "The frequency of 12 non\-metric skull variants was used to evaluate the effect of habitat isolation on genetic structure of bank vole populations. Genetic differences were compared between bank voles inhabiting an isolated patch of wood and animal caught in large, continous forest. \"Bottleneck\" efect was suggested as a possible cause of the differences found. Results are discussed in terms of genetic variability within a metapopulation."]
