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.

日本的蝙蝠种类大多数是森林蝙蝠。Ikonnikov的胡须蝙蝠，鼠耳蝠ikonnikovi是森林居住的蝙蝠物种之一。我们利用无线电遥测技术对日本尼科的鼠耳蝠（Myotis ikonnikovi）夏季白天的栖息地进行了定位和描述。2001年8月和2002年7月和8月，我们对4只成年雌性和5只成年雄性进行了16天的无线电跟踪。除了一只雌性蝙蝠之外，所有的蝙蝠都被跟踪了两天以上，因为它们每隔一两天就换一次栖息地。该Ikonnikov的须蝙蝠使用了8种树木共16个栖息地：落叶松leptolepis，榆davidana var。japonica、蒙古栎Quercus mongolica var. grosseserata、岳桦（Betula ermanii）、白桦（Betula platyphylla var.）蝙蝠的栖息地多为树干，栖息地多在树皮下。这些结果表明，丰富的障碍物的天然林可能是重要的鼠耳蝠ikonnikovi。
