Abstract

For the first time, based on sequence variation of microsatellite loci and the mtDNA cytb gene fragment, population genetic structure of the common shrew and Caucasian shrew in their contact zone was investigated. It was demonstrated that, although there was no complete reproductive isolation between the species under consideration, the gene flow was considerably limited. These data testify to the established reliable reproductive barriers between the common shrew and Caucasian shrew.
