Species Composition, Distribution, and Environmental Ecology of Voles (Mammalia, Cricetidae, Microtus) Found in the Northwest Caucasus

Аннотация

Molecular genetic typing of voles from the vicinity of the Pslukh cordon (south of the Caucasian state reserve), Krasnaya Polyana, and from the Utrish reserve (the Abrau peninsula) has been carried out. Based on the nucleotide sequence of the mitochondrial cytochrome b gene, voles from Krasnaya Polyana and the Psulkh cordon should be attributed to Asia Minor voles (Chionomys roberti), and the animals from Utrish, to the Eastern European voles (Microtus rossiaemeridionalis). The Asia Minor voles belong to the North Caucasian phylogenetic branch of the species. The analysis of body measurements of voles from Krasnaya Polyana and Lazarevskii region (without molecular examination) showed that these animals also most likely belong to the Asia Minor voles (not to Gudaurskii, as was mistakenly considered earlier). Some information on the ecology of the Asia Minor voles in the region is given.
