It remains yet to be determined to what extent high-latitude glacial refugia contributed to post-glacial colonization of Europe.This study has used mitochondrial DNA sequences (largely obtained from museum skins) to investigate whether the phylogeography of bank voles currently living in deglaciated areas north of the Carpathians reflects colonization from a high-latitude or other refugia. The results suggested the contribution of multiple glacial refugia. However, the occurrence of a Carpathian genetic clade over a large area north of the Carpathians up to the Baltic Sea coast indicated a particular importance of the Carpathian refugium. Thus, a substantial involvement of a high-latitude refugium in the post-glacial colonization of Europe by bank voles is inferred. Likely as the consequence of the high-latitude survival, the Carpathian clade lacks evidence of the severe demographic bottleneck during the Last Glacial Maximum that is observed in the Eastern clade.
