Abstract: Mitochondrial DNA cytochrome b (Cytb) gene sequences were used to assess the evolutionary history of the northern red-backed vole, Clethrionomys rutilus, in northeastern Asia. Neighbor-joining and maximum likelihood trees constructed with the Cytb gene sequences (1 140 bp) of 27 samples revealed four major local lineages; those represented by haplotypes from central Siberia, far eastern Siberia, Alaska-Kamchatska/Sakhalin, and Hokkaido. These lineages differed from one another with sequence divergences ranging from 0.0160 to 0.0298 (Kimura's distance, all substitutions at all codon positions). These findings imply that C. rutilus has inhabited the local areas during a longterm period of the evolutionary time, such as the last one or two million years, as observed in another common species of red-backed vole C. rufocanus with similar geographic distribution. The intraspecies geographic partition, however, differs between the species, implying that these two species have experienced different evolutionary histories in geographic expansion and genetic exchanges among local populations.
