The genetic structure of adders ( Vipera berus) in Fennoscandia: congruence between different kinds of genetic markers

Abstract In order to elucidate the colonization history of Fennoscandian adders ( Vipera berus ), the phylogeographical patterns of two nuclear sets of DNA markers (random amplified polymorphic DNA and microsatellite) are compared with that previously obtained from mitochondrial DNA. An eastern and...

Description
Summary:Abstract In order to elucidate the colonization history of Fennoscandian adders ( Vipera berus ), the phylogeographical patterns of two nuclear sets of DNA markers (random amplified polymorphic DNA and microsatellite) are compared with that previously obtained from mitochondrial DNA. An eastern and a western lineage within Fennoscandian adders is readily distinguishable using both sets of nuclear markers, corroborating the hypothesis that the lineages stem from separate glacial refugia. Moreover, the same contact zones as were derived from mitochondrial data are clearly identifiable. Both sets of nuclear markers detect a high level of admixture across one zone in northern Finland, with introgression reaching far west into Sweden.
