Gene-geographical variation of hemoglobins in red-backed voles (Myodes rutilus Pallas 1779) from the south of the Russian Far East
The article presents the results of electrophoretical analysis of hemoglobin in northern red-backed voles (Myodes rutilus) from the south-eastern part of Russia. The authors studied a gene-geographic variation of the species and determined its differentiations. It was identified two geographical groups. The Myodes rutilus populations of Big Shantar Island, Sakhalin Island, Hokkaido Island (Japan), and populations of red voles from neighboring Pacific coast belong to the same group. East populations of the Sikhote Alin Mountains also belong to this group. Another group includes continental populations of the Amur region and adjacent areas. The two groups are effectively parapatric, their ranges only narrovly overlapping.
