Abstract

This study was conducted to analyze the home range size of Pipistrellus abramus in non-reproductive season. The survey was conducted in the day-roosting site of Pipistrellus abramus located in Gyeongju City(North Gyeongsang Province). We radio-tracked six Pipistrellus abramus(male 3, female 3) and LTM single stage radio transmitter(0.38g), R2000 ATS receiver, three element yagi antenna, roof mounted antenna and ArcGIS 3.3(ESRI, Animal Movement Extension 2.0) were used to locate bats and home range analyze. The home range sizes of the 6 radio-tracked Pipistrellus abramus ranged from 8.97 to 19.07ha(Maen $14.46{\pm}3.44ha$). Mean home range size of female($16.83{\pm}1.96ha$) was larger than that of male($12.08{\pm}2.96ha$) but there were no significant differences in home range sizes between male and female(t=2.32, p>0.05). Also, mean maximum distances from the roost was $468.73{\pm}94.38m$ but there were no significant differences between sexes(female, $422.73{\pm}10.38m$; male, $514.74{\pm}125.74m$; t=-1.26, p>0.05).

본 연구는 집박쥐의 비번식기 행동권을 분석하기 위하여 경상북도 경주시의 집박쥐 주간 휴식장소를 대상으로 수행하였다. 박쥐의 포획은 새끼의 출산이 이루어지기 이전인 2009년 5월 4, 10, 18일에 하였으며, 암, 수 각각 3개체씩 총 6개체를 이용하였다. 행동권 분석을 위한 원격무선추적은 발신기(LTM Single Stage Radio Transmitter, 0.38g), 수신기(R2000 ATS receiver, Advanced Telemetry Systems, Inc., Isanti, MN), Yagi 안테나(Three element Yagi antenna) 및 차량용 안테나(Roof mounted antenna)를 이용하였으며, 분석에는 ArcGIS 3.3 (ESRI Inc.) Animal Movement Extension 2.0을 이용하였다. 집박쥐의 행동권 분석결과 평균 행동권은 $14.46{\pm}3.44ha$로 조사되었으며, 암컷은 $16.83{\pm}1.96ha$ 그리고 수컷은 $12.08{\pm}2.96ha$의 행동권을 가지는 것으로 나타났다. 본 연구에서는 암컷과 수컷의 행동권에서 평균적으로 암컷이 더 큰 행동권을 보이는 결과를 나타내었으나, 통계적으로 유의적인 차이는 확인되지 않았다(t=2.32, p>0.05). 또한 각각의 위치정보를 기준으로 주간 휴식지에서의 최대 이동 거리는 평균 $468.73{\pm}94.38m$ 로 나타났으며, 암컷($422.73{\pm}10.38m$)과 수컷($514.74{\pm}125.74m$)간의 유의적인 차이는 나타나지 않았다(t=-1.26, p>0.05).
