尾瀬のコウモリ相を把握するため，2017～2019年の6～10月に，森林での捕獲調査とねぐら探索調査を行った．その結果，2科8属11種132個体が確認され，コキクガシラコウモリ，モリアブラコウモリ，ノレンコウモリが尾瀬で新たに確認された．過去の記録とあわせて，尾瀬で確認されたコウモリ類は2科9属14種になった．森林での捕獲調査で，捕獲地点数・個体数ともに最も多い種はヒメホオヒゲコウモリだった．尾瀬のヒメホオヒゲコウモリの遺伝的特徴を明らかにするため，分子生物学的な分析を行った．遺伝子多様度は0.82583，塩基多様度は0.00219だった．他地域の個体を含めたハプロタイプネットワークでは，複数のグループに分かれなかった．
The bat fauna was surveyed from June to October of 2017-2019 in Oze region, central Japan. In this survey, a total of 132 bats were captured representing 11 species, 8 genera, 2 families. Rhinolophus cornutus Temminck, 1834, Pipistrellus endoi Imaizumi, 1959 and Myotis bombinus Thomas, 1906 were first recorded in this area. The bat records in Oze, including past records, are 14 species, 9 genera, 2 families. Based on mist-nets and harp trap surveys, the most captured bat species is Myotis ikonnikovi Ognev, 1912. We investigated about genetic variations of M. ikonnikovi in this area. The genetic diversity and the nucleotide diversity were 0.82583 and 0.00219, respectively. Based on the haplotype network analysis comparing with other regions, it was not confirmed that the individuals analyzed were clearly divided into some specific groups.
