英文摘要	The estuarine areas are under frequent influence from freshwater intrusion and ocean currents, in which zooplankton species are diversified and variable as they are sensitive to physio-chemical variations in water. Therefore, understanding the relationships between zooplankton and environmental factors help us know the water quality. To achieve co-existence with species in similar ecological group or habit, they could inevitably alter themselves to fit the ecology and adjust the function according to the competitive exclusion in ecological theory. However, information of the co-existence of dominant species in the Changjiang (Yangtze) River estuary (CRE) and adjacent waters remains scarce. We explored the relationships between dominant zooplankton and environmental factors in the study region in spring-summer from 2016 to 2020, involving particularly the composition of dominant species, ecological groups, their relationships with environmental factors, and co-existence of important species, using the non-multidimensional scale analysis (nMDS) method and redundancy analysis. Results show that Labidocera euchaeta and Tortanus vermiculus were dominant species in the study scope. The turnover rate of dominant zooplankton was greater (>50%) in spring while the species number was higher in summer. The dominant species were estuarine, offshore, and eurytopic based on the adaptation to salinity. In spring, the ecological groups were dominated by estuarine species, while in summer by estuarine and offshore species. In addition, the nMDS showed that the dominant species in the same ecological group were more dispersed and not prominently clustered; the dominant species were staggered among different ecological groups. The temperature, salinity, pH, dissolved oxygen, and chlorophyll a were the main environmental factors on the distribution of the dominant species in spring, while in summer were dissolved oxygen, temperature, salinity, and pH. The domination of medusae of Nemopsis bachei and Pleurobrachia globosa in zooplankton community in spring, and the continuous decrease in abundance of L. euchaeta reflected the effects of local climate change. The temperature and salinity changes in different years and the subsequent response of zooplankton reflected the influence of freshwater intrusion and/or ocean currents. Zooplankton in similar ecological habits exhibited the competitive exclusion in terms of co-existence.
