We studied the influence certain environmental factors (proximity of roosting site, roads, and residential areas) have on the spatial distribution of cranes in the Cheorwon, Korea. Using a range finder and GPS, data were collected from January to February 2007 and were subsequently evaluated with Ar...

두루미류의 공간적분포는 무엇이 혼재된 양상을 보여주는가? | , 1996). 두루미류의 공간적분포(spatial distribution)는 가족군의 세력권 형성 (Alonso et al., 2004)에 의한 규칙적 분포와, 비가족군에 의한 임의분포(Ohsako, 1989)가 혼재된 양상을 보여주고 있다. 또한, 인공먹이급여(Yoo, 2004) 및 잠자리(Pae, 1994; Spalding and Kraup, 1994), 잠자리와 취식지 간의 일주행동(Pae, 2000), 민간인통제지역(Civilian Control Zone, CCZ: Yoo et al. | |
본 연구에서 잠자리를 이용하는 개체군 조사를 시행할 때, 무엇을 기록했는가? | 잠자리를 이용하는 개체군 조사는 분포조사일과 같은 날일출시간 30분 전부터 대부분의 개체군이 취식지로 이동했다고 판단되는 시간(5분간의 비행개체수의 합계가 0개체이며 지속시간이 30분일 경우)까지 이루어졌으며(Yoo, 2004), 잠자리와 취식지 사이 2군데 이상의 지점에서 정점조사를 실시하였다. 조사시 종 구분과 비행무리의 개체수를 기록하였다. 한 지역 당 1곳 혹은 2곳에서 조사하였으며, 2개 지점 간의 중복 관찰을 피하기 위하여 타 조사지점의 방향으로 이동하는 두루미류는 무전기를 이용하여 종과 개체수를 확인하여 개체수 중복을 피하였다. | |
생물체의 분포는 어떤 형태로 구분하는가? | 생물체의 분포는 크게 구분하여 임의분포(random), 규칙 적인 분포(regular), 집단분포(aggregated)의 형태를 보인다 (Perrins and Birkhead, 1983; Begon et al., 1996). |
