BACKGROUND: In recent year, there has been great concern regarding agricultural land uses and their importance for the conservation of biodiversity. Rice fields are managed unique wetland for wildlife, especially waterbirds. A comprehensive monitoring of the waterbird assemblage to understand patter...

논습지의 역할은 무엇인가? | 논습지(rice fields)는 많은 수의 조류가 이용하는 대표적인 인공습지로 잘 알려져 있다(Elphick, 2010). 개발로 인하여 사라져가는 자연습지를 대신하여 논습지는 다양한 수조류에게 서식지를 제공한다(Fasola and Ruiz, 1996; Elphick, 2000). 백로류 같은 일부 수조류 그룹에게 안정적인 개체군 유지를 위해 취식지로서 기능을 가지는 논습지의 분포는 필수적이다(Czech and Parsons, 2002). | |
랜덤 포레스트 분석 방법의 장점은 무엇인가? | , 2012). 최근 들어 랜덤 포레스트 분석 방법은 생태학 분야에 많이 접목되는 방법으로 복수의 의사결정나무를 이용하여 단일 의사결정 분석의 과적합(overfitting) 문제를 피할 수 있다는 장점을 가진다(Breiman, 2001). | |
한국 중서부지역에 위치한 아산호와 아산만 남단 지역의 논습지를 연구 지역으로 하여 수조류 군집을 파악한 이유는? | 1). 이 지역은 봄철 이동시기에는 도요물떼새류, 여름철에는 백로류, 겨울철에는 오리기러기류와 같이 다양한 조류가 도래하는 중요한 지역이다. 백로류의 경우 번식 개체군으로 왜가리, 중대백로, 중백로, 쇠백로, 황로, 해오라기 등이 조사 지역 주변에 대단위 번식을 한다(Choi et al., 2007; Choi and Yoo, 2011). 더군다나 연구 지역은 동아시아-대양주 철새이동경로(East Asian-Australian Flyway)상에 위치하고 있고 이 경로로 멸종위기조류종이 이용하고 있어 보전에 중요하다(BirdLife International, 2005). |
