Abstract: Synopsis. Distribution of shrews (Soricinae: Soricidae: Insectivora) and their mitochondrial gene types were investigated in the Shiretoko Peninsula. Shrews were collcted at low, medium, and high locations of both slope sides of the central mountains, Utoro and Rausu sides. Sorex unguiculatus, S. gracillimus, and S. caecutiens were captured, but the number of captured S. caecutiens was small. Sorex unguiculatus tended to be numerically dominant on Rausu side, and so did S. gracillumus on Utoro side. Densities of both of S. unguiculatus and S. gracillimus were higher on Rausu side than on Utoro side, while those did not variate among three different altitudes. 402-base regions of the mitochondrial cytochrome b gene were sequenced in 30 S. unguiculatus, and 14 gene types (haplotypes) were recognized. No clear difference in the distribution of the types was observed between altitudes nor slope sides, although it was implied that distributions of some gene types might deviate between the two sides.
