Functional traits of zooplankton community in the South Yellow Sea during autumn 2022
摘要
Abstract
To explore the community structure and functional traits of zooplankton in the South Yellow Sea during autumn,this study analyzed species composition and abundance while identifying the dominant species,functional traits,and functional groups based on samples collected in 2022.A total of 84 adult species and 28 pelagic larvae were documented,with copepods being the most diverse.The average abundance was 4087.4±2613.9 ind./m3.Cluster analysis classified the assemblages into two distinct groups,namely,the Yellow Sea Coastal Group and the Central Yellow Sea Group,which were roughly demarcated by the sea surface 31 isohaline.Significant intergroup differences were detected in species composition(R=0.809,P<0.001)and environmental factors(P<0.05).Bio-diversity indices,species richness index,species evenness index,and Shannon-Wiener index,revealed that the Yel-low Sea Coastal Group was more diverse than the other group.Dominant species within the former included Para-calanus parvus,Oithona similis,and Oikopleura dioica,with functional traits dominated by small body size(<1 mm),current feeding,omnivore-herbivore,and broadcast spawner.The Central Group was dominated by co-pepods,with functional traits characterized by small body size(<1 mm),ambush feeding,omnivore-herbivore,and sac spawner bearing.The relative abundance of the two groups differed within the nine functional groups identified based on functional traits.Bottom salinity was identified as the primary driver of spatial variations in functional traits and space of the zooplankton community(P<0.05);it was followed by bottom temperature and chlorophyll-a concentration.This study provides fundamental data for further understanding the ecological patterns of zooplank-ton communities within the South Yellow Sea during autumn.关键词
