ABSTRACT. A range-wide phylogeographic study of the gray red-backed vole (Craseomys rufocanus), was carried out using cytochrome b and cytochrome oxidase subunit I of mtDNA and a fragment of the Y-chromosome SRY gene. The results, based on 271 specimens from 81 localities over the majority of the species distribution, demonstrate that there are four main mitochondrial lineages with partly sympatric distribution. Spatial distribution of SRY haplotypes generally coincides with the mitochondrial distribution, being different mainly in details. However one of the mitochondrial lineages is not reflected in Y-chromosome based data. Most of the genetic diversity of C. rufocanus is allocated within the south-eastern part of the range, where representatives of all discovered mtDNA lineages and most of the SRY haplogroups have been found. The observed genetic structure could be explained by repeated glacial fragmentation of the species range together with following dispersion from several refugia.
