A highly divergent mitochondrial DNA lineage of Microtus agrestis in southern Europe

Jaarola, Maarit LU and Searle, JB (2004) In Heredity 92(3). p.228-234
Abstract
The Mediterranean peninsulas constitute important areas for endemism and intraspecific variation, and are likely places for cryptic biodiversity. We assessed the phylogeographic pattern of field voles ( Microtus agrestis) in southern and central Europe by sequence analysis of a 385-bp fragment of the mitochondrial cytochrome b gene in 74 specimens from 44 localities. The majority of samples consisted of skulls collected from owl pellets. The data revealed a highly distinct cytochrome b lineage in an area ranging from Portugal to Hungary. This southern field vole phylogroup differed by a sequence divergence of 5.6 - 7.1% from the remaining haplotypes, a level of divergence comparable to that found between known Microtus sibling species....

The Mediterranean peninsulas constitute important areas for endemism and intraspecific variation, and are likely places for cryptic biodiversity. We assessed the phylogeographic pattern of field voles ( Microtus agrestis) in southern and central Europe by sequence analysis of a 385-bp fragment of the mitochondrial cytochrome b gene in 74 specimens from 44 localities. The majority of samples consisted of skulls collected from owl pellets. The data revealed a highly distinct cytochrome b lineage in an area ranging from Portugal to Hungary. This southern field vole phylogroup differed by a sequence divergence of 5.6 - 7.1% from the remaining haplotypes, a level of divergence comparable to that found between known Microtus sibling species. However, this ancient phylogeographic break that dates back many glacial cycles has not been recognised previously by either morphology or karyotype. The southern cytochrome b lineage was further divided into two well-defined sublineages that appear to have derived from different glacial refugia in the Iberian Peninsula. (Less)
