Abstract

Forty lesser Japanese moles (Mogera imaizumii) were trapped on Kinkazan Island, which is a small island (959 ha) located 1 km off Honshu in northern Japan. Of these, 36 moles (90%) showed some degree of partial albinism of the fur, ranging from only small tufts of cream-colored hairs on their basal forefoot to multiple large interconnected patches spread around the whole body. Most tufts, spots and patches were cream-colored, but some tufts and spots on the lower abdomen were light brown. This coloration is attributable to staining by a secretion from skin glands that are distributed ventrally, with a higher density in the lower abdomen. The high frequency of partial albinism may be attributable to a lack of predators in this insular ecosystem or to low genetic diversity in the population, although it is difficult to know which of these two is more important.
