[Polymorphism and Genetic Structure of Microtus maximowiczii (Schrenck, 1858) (Rodentia, Cricetidae) from the Middle Amur River Region as Inferred from Sequencing of the mtDNA Control Region].

The genetic variability of the mitochondrial DNA control region sequences was estimated for the Maximowicz's vole Microtus maximowiczii from the Middle Amur River region located between the confluence of Amur River with Ussuri River and Zeya River. The species as a whole was characterized by a high level of genetic variability. For each individual sample, low nucleotide diversity was observed, except for two samples in which a more than twofold increase in this index was revealed.
