Voles of the Genus Alexandromys from the Verkhnebureinskaya Depression

详细

Voles of an unclear taxonomic status have been found in the Bureya River depression (Khabarovsk krai) for the first time. An analysis of the nucleotide sequence of the control region in two individuals revealed their greatest similarity with species of the “maximowiczii” group. The minimum p-distance (0.0217 ± 0.0044) was observed between individuals from the Bureya River depression and Alexandromys evoronensis studied earlier. The karyotype of one individual studied had a chromosomal aberration distinguished at the heterozygous state (2n = 37; NF = 55). A similar karyotype was described in the polymorphic A. maximowiczii population from the Khentii Mountains in Mongolia.
