Abstract

Multiple temporal scale can be a useful method to understand population dynamics in ecosystem. The multi-temporal scale approach for population dynamics has rarely been researched till lately. This study was carried out to identify the factors in affecting the population dynamics of herons, including Eastern Cattle Egret (Bubulcus coromadus), Grey Heron (Ardea cinerea), Great Egret (A. alba), Intermediate Egret (Egretta intermedia) and Little Egret (E. garzetta), at rice paddy fields of Seokmun-myeon in the city of Dangjin, South Chungcheong Province during the main breeding periods from 2014 to 2017. We identified the population dynamics of herons at different time interval (day and month) using the unmanned monitoring system. As a result, monthly population dynamics was mostly affected by time, mean temperature and mean precipitation, whereas daily population dynamics was affected by mean temperature and habitat types. The results suggest that there are differences in the factors affecting the population dynamics of herons according to the time scale.

생태계 내에서 개체군 변동을 이해하는데 다양한 시간 스케일에서의 분석이 유용한 방법이 될 수 있다. 최근까지 다양한 시간 스케일에서의 개체군 변동에 대한 연구는 거의 드물다. 본 연구는 2014년부터 2017년까지 4년간 충남 당진시 석문면 논에 도래하는 백로류 개체군을 대상으로 시간 스케일에 따른 이들 개체군 변동에 영향을 미치는 요인을 확인하기 위해 수행되었다. 백로류는 황로, 왜가리, 중대백로, 중백로, 쇠백로만을 대상으로 하였으며, 고정된 지점에 설치된 무인모니터링 시스템을 활용하여 백로류의 개체군 변동을 다른 시간 단위의 스케일인 월 단위와 일 단위 변동으로 나누어 확인하였다. 그 결과, 월별 개체군 변동에 영향을 미치는 요인은 시기, 평균 온도, 평균 강수량으로 나타났고, 일별 개체군 변동에 영향을 미치는 요인은 평균 온도와 서식지 유형이 중요한 것으로 확인되었다. 시기의 통계적 유의성이 일 단위에서는 나타나지 않고 월 단위에서 확인된 이유는 백로류의 논 이용 패턴이 일 단위보다는 월 단위 스케일에서 명확히 구별되기 때문으로 판단된다. 이를 통해 시간 스케일에 따라 백로류에 영향을 미치는 요인에 차이가 있다는 것을 확인할 수 있었다.
