Habitat evaluation of birds community at urban green spaces focused on nested structure

Abstract

The purpose of this study is to categorize species composition of urban avifauna community using beta diversity and nestedness analysis at eight districts of Matsudo-city, Chiba, Japan. The eight districts were classified into four types of species composition: high/low of beta diversity x exist/absent of nestedness. Additionally, to figure out the factors that affect the species composition, we use nMDS plotting. nMDS plotting indicated that the species composition of the study area extended on the dimension relationing to woods area, water area, farm area and urban area. Every type of the species composition indicated different pattern on the nMDS dimension.
