高知県中部の鉄道高架橋をねぐら利用するコウモリ類

抄録

In November 2016, a total of 541 crevices at the junctions of elevated railways were visually inspected in central Kochi Prefecture to assess the roost use by bats. The author found 775 bats in 161 crevices. All bats were considered to be the common Japanese pipistrelle Pipistrellus abramus, and rare bat species were not found. Although the urban environment had positive effects on the roost use by bats, cultivated lands and forests had negative effects on it.
