Abstract

The purpose of this study is to identify the home range and habitat using pattern of the native species, Mauremys reevesii, and the exotic species, Trachemys scripta elegans, and to analyze the mutual competition relationship of the two species. This study was conducted at the Goldfish square pond, which is located in the upper part of the valley of Cheonggye mountain from August 2, 2010 to January 30, 2011. We used the three artificially proliferating M. reevesii and three T. scripta elegans which were inhabited in the ponds and reservoirs for monitoring study after attaching the transmitter to each of them. We measured the home range and the habitat utilization radius of three individuals of each species and the environmental factors such as temperature, humidity and soil and water temperature around the Goldfish square pond. As our results, it was analyzed that the M. reevesii and T. scripta elegans have a redundant ecological positions in various aspects such as limited sunbathing places, food resource utilization, hibernation place, etc. We also found that the relatively small M. reevesii was being pushed out of the competition by the relatively big. Further investigation of food competition and habitat utilization should be necessary for these two species for the natural habitats, their home range, food competition, and habitat utilization. The result of this study will be the basic data M. reevesii's restoration project.

본 연구의 목적은 국내산 남생이와 외래종 붉은귀거북의 행동권 및 서식지 이용 패턴을 확인하고 종간 상호 경쟁관계를 분석하는 것이다. 본 연구는 2010년 8월 2일부터 2011년 1월 30일까지 경기도 과천시 청계산 계곡 상류지역에 위치한 정수역인 금붕어광장 연못에서 수행되었다. 서울동물원에서 인공증식한 남생이 3개체와 국내의 연못과 저수지에 서식하고 있던 붉은귀거북 3개체를 포획하여 위치추적발신기를 부착한 후 방사하여 모니터링을 수행하였다. 방사된 개체들의 행동권과, 서식지 이용반경을 측정하였고, 금붕어광장 연못의 온 습도 및 수온, 지온 등 환경적인 변화를 측정하였다. 본 연구 결과는 남생이와 붉은귀거북은 제한된 일광욕 장소, 먹이자원 이용, 동면지 등 여러 측면에서 중복된 생태적 지위를 가지고 있어서 상호 경쟁이 큰 것으로 분석되었다. 비교적 몸집이 작은 남생이가 몸집이 큰 붉은귀거북에게 경쟁에서 밀려나는 것을 확인할 수 있었다. 남생이가 서식하고 있는 원서식지에 붉은귀거북의 이입을 통한 종간, 개체간의 행동권과 먹이경쟁, 서식지 이용 등에 대한 연구가 추가적으로 필요할 것으로 사료되며, 추후 남생이 복원사업의 기초자료가 될 것이다.
