To explore the relationships between environmental factors and zooplanktonic beta diversity—and its component changes—zooplankton samples and corresponding environmental data were collected from 24 stations in Xiangshan Bay.Zooplanktonic beta diversity was analyzed by a generalized dissimilarity model( GDM) with the gdm package in the R language,and was further separated into two components—turnover and nestedness—using the betapart package. Analytical results with GDM showed that 10 environmental variables...
