コイボクシュシビチャリ川の標高320m付近で捕獲したCrocidura dsinezumi

抄録

Even though a rare species in Hokkaido, most Crocidura dsinezumi have been found in areas between 100m to 200m above sea level. However, in August 2001, the authors captured three male animals at a higher altitude of about 320m above sea level near the Koibokushushibichari River. The head and body length of the three animals captured by the authors were slightly smaller than the four specimens captured by Abe et al. (1987) and the one specimen captured by Nakata (1981) in Hokkaido. The animals captured near the Koibokushushibichari River were closer in size to the larger animals found in the north of Honshu. The tail length of all the specimens mentioned above was longer than those of the specimens found in Honshu and other southern Islands. The foot length of the specimens captured by the authors, Abe et al. and Nakata were approximately the same. The dimensions of the cranium of the specimens found by the authors and Abe et al. were approximately the same. The cranium and foot size were larger than those found in Honshu and more comparable with the larger animals found on Tanegashima and Yakushima. The tooth low lengths of the specimens captured by the authors were as large as or larger than the largest tooth low length of the specimens found in Honshu and other southern Islands.
