Research Abstract

Most of bats spesies in Japan are forest-dwelling bats. The Ikonnikov's whiskered bats, Myotis ikonnikovi is one of the forest-dwelling bat species. The distribution of the Ikonnikov's whiskered bat depends on the distribution of natural forest.
We used radiotelemetry to locate and characterize the daytime summer roosts of Ikonnikov's whiskered bats, Myotis ikonnikovi, in Nikko, Japan. We radiotracked 4 adult females and 5 adult males as they used 16 day roosts in temperate deciduous forest in August 2001 and July and August 2002. All bats but one female were followed for more than two subsequent days as they changed roosts every one or two days. The Ikonnikov's whiskered bats used a total of 16 roost in 8 species of trees : Larix leptolepis, Ulmus davidana var. japonica, Quercus mongolica var. grosseserrata, Betula ermanii, Betula platyphylla var. japonica, and so on. Most of the roost trees were snags and most of the bat roosting site were under the bark. These results indicated that abundance of snags in natural forest may be important for the Myotis ikonnikovi.
