초록

환경특성에 따른 집박쥐(Pipistrellus abramus)의 반향정위 변화를 분석하기 위하여 2009년 4월부터 8월까지 경상북도 경주시 천북면 일원의 주간 휴식장소를 대상으로 실시하였다. 환경특성 유형은 일몰 후 출현순간, 출현 후 이동, 논 경작지, 산림 가장자리, 개방공간, 주택단지 등 6개 유형으로 구분하여 비교하였다. 분석결과 환경특성에 따른 차이 및 서식지간 이동과 먹이포획을 위한 비행 사이에서는 차이가 있는 것으로 나타났다. 외부 환경으로의 출현 순간에서는 짧은 시간의 FM 시그널만 확인되었으며, 개방 공간에서는 긴 시간의 CF 시그널 형태의 음을 이용하는 것으로 나타났다. 그 외 환경특성에서는 펄스의 형태적인 차이는 있었지만 FM과 CF 시그널을 혼합하여 이용하는 것으로 확인되었다. 먹이포획을 위한 비행과 서식지간 이동을 위한 비행에서는 펄스의 지속시간을 제외한 펄스 간격, 최고 진동수, 개시부와 종결부 진동수에서는 두 가지 비행패턴 사이에서 유의적인 차이가 확인되었다. 출현순간을 제외하고 서식지간 이동을 위한 비행시에는 곤충의 반향을 감지하여 곤충의 탐색에 적합한 협대역의 FM 시그널과 긴 펄스 지속시간을 가지는 형태를 보였으며, 먹이포획을 위한 비행에서는 폭넓은 탐색과 정확한 위치파악을 위한 광대역의 FM 시그널과 짧은 시간의 펄스 지속시간을 갖는 것으로 확인되었다.

This study was conducted to analyze the changes in the echolocation of Pipistrellus abramus according to environmental characteristics. The survey was conducted in the day-roosting site of P. abramus located in Gyeongju City (North Gyeongsang Province) from April to August, 2009. The environmental characteristics during the research were classified in six categories: the emergence time after sunset moving time from day roost to feeding areas; rice fields; forest edges; open spaces; and residential areas. Analysis results showed that there are differences in environmental characteristics and also differences between the moving time to the habitat and the moving time to capture preys. At the emergence time from day roost, Pipistrellus abramus used a FM signal with a short pulse-duration. In open spaces, however, they used a CF signal with a long pulse-duration. In different environmental situations, they used both FM and CF signals, although the types of pulse which they used were different. Except pulse-duration, there were significant differences in pulse-interval, peak-frequency, starting-frequency and ending-frequency between the movement among habitats and the movement to capture preys. Except the emergence time from day-roost, they showed a narrow band FM signal and a long pulse-duration that are suitable to search for insects by sensing echoes of insects when they moved among their habitats. When they were out to capture their preys, they showed a broad band FM signal and a short pulse-duration which enabled them to widely search and accurately locate their preys.
