Mokoto, Hokkaido. Radio transmitters were attached to some captured individuals to locate their roosts. The investigation was conducted at 61 sites, considering the characteristics of each place, such as the living environment and altitude. In forests, although capture rates were low at altitudes of 100 to 300m (secondary broadleaved forests with larch plantations), Myotis ikonnikovi and Murina ussuriensis together accounted for 49.7% of all captured individuals, regardless of the altitude and flora. Plecotus sacrimontis were captured at altitudes above 820m and were observed at the highest altitude in Hokkaido. Myotis macrodactylus, was captured more frequently along fast flowing rivers, compared with Myotis petax. Breeding roosts were observed at 4 sites of investigation, one of which, a tree hollow, was identified as that of Myotis petax by telemetry. In order to protect bats, it may be necessary to investigate the actual use of breeding roosts, and telemetry may play an important role in such an investigation. In bat fauna of Mt. Mokoto, there are many individuals and species of broadleaved- coniferous forest at high altitude, but only a small number of larch forest, secondary of broad-coniferous forest and farmland forest., E, 6, KJ00007242244, 論文, Article}, pages = {155--161}, title = {北海道藻琴山を起点とする3河川流域のコウモリ相}, volume = {56}, year = {}, yomi = {スガイ, ショウタロウ and コンドウ, ノリヒサ and ソウマ, コウサク and マスコ, タカヨシ} }
