초록
이 연구는 현재까지 국내 야생에서 확인되지 않았던 외래종 견목거북과(Podocnemididae) 아마존노란점거북(Yellow-spotted Amazon River Turtle, Podocnemis unifilis)을 처음으로 관찰한 사실을 학술적으로 보고하고자 한다. 2020년 7월 24일 제주특별자치도 제주시 조천읍 와흘리 33°30'20.08"N 126°38'0.23"E 지점에서 아마존노란점거북 2개체가 바위에서 일광욕하고 있는 것이 관찰되었다. 1개체는 머리에 노란색 반점이 있었고, 다른 1개체는 흑화되어 검은색을 띠었다. 관찰된 장소는 도로와 인접해 있고, 사람들의 출입이 잦은 곳으로, 애완용으로 사육되던 개체가 연못으로 방사된 것으로 추측된다. 최근 호수, 저수지 등 국내 야생에서 확인되는 외래거북이 증가하고 있으며, 외래거북 유입으로 인한 수생태계의 피해가 예상되는 만큼, 외래생물에 대한 시민과학 프로젝트와 환경교육을 통한 대중들의 인식 개선이 필요하다. 향후 발견된 개체에 대하여 지속적인 모니터링을 통한 야생 적응 여부, 번식과 관련된 추가 연구가 수행되어야 할 것이다.
Abstract
This study is the first official report on the wild habitats of alien species, Yellow-spotted Amazon River Turtle (Podocnemis unifilis) in Republic of Korea. On July 24, 2020, two P.unifilis were observed basking on rocks at 33°30'20.08"N 126°38'0.23"E, Waheul-ri, Jocheon-eup, Jeju-si, Jeju. One individual had a yellow spots on the head where as the other contains black spot. Our observatory site is close to road and easy access to people. Thus, these individuals were believed to be released in the pond after raising as pets. Recently, the number of alien turtles identified in wild(etc. lake, resevoir) is increasing, which is predicted to damage the aquatic ecosystem due to the inflow of exotic turtles. So, it is necessary to improve the people's awareness of alien species through citizen science projects and environmental education. We suggest that research on habitat adaptation, reproduction and management through continuous monitoring is needed in the future.
