Inferring phylogenetic relationships in the common vole (Microtus arvalis) based on mitochondrial and nuclear sequence diversities

The common vole Microtus arvalis (Pallas, 1778) is the most widespread species. It has two forms - European form (2n: 46, NF: 84) and Asian obscurus 72). present study aimed to clarify taxonomic status of M. populations distributed in Eastern Turkey, Europe Asia by analysing mitochondrial (CYTB COX1) one nuclear (IRBP) markers. Phylogenetic dendrograms (median-joining networks Bayesian trees) constructed using markers clearly separated Anatolian population from populations. Contrarily, any explicit differentiation was not shown IRBP analyses. Mean net genetic distance values (d) were found be notably low for three Species delimitation test (Automatic Barcode Gap Discovery Method) supported these results. Our results indicate that are sufficiently differentiated considered different species, while only recently split population. Together, findings demonstrate speciation process ongoing.
