초록

산림을 주 서식지로 이용하는 쇠큰수염박쥐 (Myotis ikonnikovi) 의 서식지 특징에 관하여 연구하였다 . 안개그물을 이용한 포획조사를 통해 확인된 쇠큰수염박쥐서식지는 비교적 수령이 오래되고 흉고직경이 굵은 활엽수가 우점하는 숲으로 평가되었다 . 소형무선추적장치를 통해 쇠큰수염박쥐의 잠자리는 주로 활엽수의 수피틈 , 꺾어진 줄기의 틈 , 옹이 기둥 접합 부분의 틈 등으로확인되었다 . 낮동안 이용한 잠자리는 포획지점으로부터35~584m 이내에 위치하였으며 , 개체당 잠자리는 1~5 일간 이용하였다 . 쇠큰수염박쥐와 같은 산림성 박쥐류의다양성을 높이기 위하여 산림내 다양한 먹이자원이 풍부하고 , 이용가능한 다수의 잠자리가 확보될 수 있는 산림서식지 관리방안이 요구된다.

Little is known about foraging and roosting habitat of tree-roosting bats in Korea. In the present study, we studied on characteristics of foraging and roosting habitats by Ikonnikov’s whiskered bats (Myotis ikonnikovi) in the South Korea, using trapping and radiotelemetry. We captured the bats at 15 sites during nights (foraging times) using mist-nets. Based on characteristic analyses of forests within a radius 500 m from each capture site, forests of M. ikonnikovi habitat are similar characteristics to the old-growth forests. They foraged at forests dominated by boradleaf stands which are older than than 30-year-old and thicker than 20cm in diamete r at breast height(DBH). We used radio-transmitters to locate and characterize day-roosts of Myotis ikonnikovi, and totally the roost use patterns of three bats were surveyed. They roosted in trees (both live and dead) with exfoliating bark, extensive vertical cracks, or cavities, and thier roosting sites were located about 500m from the initial capture location. The bats had a number of roost in a short-distance, some used new roost every day and the same roost sometimes were used repeatedly. To increase the diversity of the tree-dwelling bats including Myotis ikonnikovi, management practices that the higher food and roost availablility can be sustained in forests are needed.
