功能性状和功能多样性指标反映了群落结构的变化，反映了它们对环境胁迫的响应。本研究基于体长、摄食类型、营养类群和繁殖方式4个功能特征，对2019年4个季节黄海南部海域甲壳类浮游动物的功能多样性和功能类群进行了研究。共鉴定出53种，分为6个功能类群。春季以埋伏捕食和杂食性-肉食性桡足类（Ⅱ组）为主（55.6%），其余季节以杂食性-草食性桡足类（Ⅰ组）数量最多（>54.7%）。功能多样性指数在不同季节的可比分布很可能与水文变化有关。长江稀释水促进了不同功能类群所携带的多种特征（高功能丰富度（FRic）和功能分散度（FDis））的共存，但该水体的生态系统功能稳定性容易受到夏季单个物种损失（低功能均匀度（FEve））的影响。在冬季，由于黄海暖流的影响，暖水类群的frc和FEve增加，表明该群落可以更有效地缓冲环境波动。此外，FRic值的分布指示了黄海冷水团的可能范围和影响强度。
Functional trait and functional diversity indices reflect the variations of community structure and indicate their responses to environmental stress. In this study, based on four functional traits, including body length, feeding type, trophic group, and reproductive mode, the functional diversity and functional groups of crustacean zooplankton from the southern Yellow Sea (SYS) were explored over four seasons of 2019. A total of 53 species were identified and categorized into six functional groups. Copepods with ambush-feeding and omnivore–carnivore diet (Group Ⅱ) were dominant in spring (55.6%), while omnivore–herbivore copepods (Group Ⅰ) were the most abundant group in the other three seasons (>54.7%). The comparable distributions of functional diversity indices in different seasons were most likely due to hydrological variations. The Changjiang River Diluted Water promoted the coexistence of multiple traits carried by different functional groups (high functional richness (FRic) and functional dispersion (FDis)), but the stability of ecosystem function in this water mass was vulnerable to the loss of individual species (low functional evenness (FEve)) in summer. In winter, as a result of the Yellow Sea Warm Current, warm-water taxa increased FRic and FEve, suggesting that the community could buffer environmental fluctuations more effectively. Moreover, distribution of FRic values indicates the possible range and influence intensity of the Yellow Sea Cold Water Mass.
