Effects of habitat fragmentation on nesting site selection of red-crowned crane

Abstract

Abstract: During April and May of 1985,1995 and 1998, red crowned crane's nesting and variation of breeding population quantities in Shuangtaihekou National Natural Reserve in Liaoning,and also the habitat fragmentation there were investigated. Associated with previous data of the reserve, red crowned crane's nesting habitat had been seriously fragmentated into 91 patches from one integrated reed wetland.The area of the smallest patch was 0.37km²,and the minimum distance of two nests was 304m.Compared with records of previous data,the minimum area of nesting habitat reduced by 0.72km².However,the breeding population quantities of red crowned crane had maintained at about 30 pairs for a long period.The red crowned crane adapted to the changed environment by the ecological adaptation strategy of reducing area of nesting habitat.

Key words: Red-crowned crane, Habitat fragmentation, Nest site selection, first-order branch distribution, Pinus koraiensis, Poisson regression model, negative binomial regression model., second-order branch distribution
