南黄海大型底栖动物群落划分及变化
Variations of Macrofaunal Community Classification in the South Yellow Sea
摘要
Abstract
[Objective]This research was aimed to give insight into the macrofaunal community structure in the South Yellow Sea and to provide scientific foundation for ecological environment protection in future.[Methods]Based on the samples collected in the South Yellow Sea during June,August and October,2012,the macrofaunal data were analyzed by using cluster analysis (CLUSTER ),non-metric multi-dimensional scaling (nMDS),one-way analysis of similarity (One-way ANOSIM)and similarity percentages (SIMPER ) methods.[Results]CLUSTER and nMDS showed that the macrofauna could be classified into 4~5 groups on the 20% similarity level.One-way ANOSIM analysis revealed that the macrofaunal communities among three months were significantly different in the South Yellow Sea.SIMPER analysis uncovered that the dominant species in different groups were also different,with Echinodermata and Mollusca dominated the community in the Yellow Sea Cold Water Mass and Polychaeta in others.[Con-clusion]Compared with previous reports,the macrofauna in the South Yellow Sea had changed drastically for over half a century,and were classified into three communities,i.e.,the Yellow Sea Cold Water Mass community,the mixed community and the eurythermal community.Echi-noderm Ophiura sarsii vadicola replaced Mollusca and Crustacea as the most dominant species in the Yellow Sea Cold Water Mass community.Polychaeta replaced Echinodermata and Mol-lusca as the dominant species in the mixed community and the eurythermal community.关键词
