Abstract

This study was conducted to clarify the environmental variables that affect the appearance of Mauremys reevesii and to understand the relationship between M. reevesii and the variables. Habitat environmental survey was implemented by selecting 17 environmental variables considering ecological characteristics of M. reevesii in the main reservoir in Gurye-gun, the Republic of Korea. And the habitat data on the presence and absence of M.reevesii were analyzed statistically. The habitat suitability model of M. reevesii was described in following equation : logit (p) = -3.68 + (0.17 × leaf litter depth) + (1.55 × vegetation coverage of overstory on land) + (0.71 × coverage of midstory on land) + (0.96 × vegetation coverage of understory on water). This information gained is valuable for better understanding the distribution and how to conserve and promote populations of M. reevesii occurring in the Republic of Korea.

본 연구는 남생이의 출현에 영향을 주는 환경변수를 파악하고 남생이와 환경변수 간의 관계를 파악하기 위해 전라남도 구례군의 주요 저수지에서 남생이 생태 특성을 고려한 17개의 환경변수를 선정하여 서식지 환경 조사를 실시하고, 서식지와 비서식지의 조사 결과를 통계 분석하였다. 남생이의 서식지 적합성 모델을 개발한 결과, 변수 예측값은 logit (p) = -3.68 + (0.17 × 낙엽층두께) + (1.55 × 육상아교목층 피도량) + (0.71 × 육상초본층 피도량) + (0.96 × 수상초본층 피도량)으로 산출되었다. 남생이는 낙엽층두께가 두꺼울수록, 육상교목층 피도량, 육상관목층 피도량, 수상초본층 피도량이 높을수록 출현확률이 높아지는 것으로 파악되었다. 남생이의 출현에 영향을 주는 이러한 환경요인에 대한 정보는 추후 남생이 분포조사 시 도움이 되며, 남생이의 실질적인 서식지 보전을 위해 필요할 것으로 판단된다.
