无毒甲藻原甲藻东海原甲藻的大量繁殖在东海很常见；然而，这些水华对浮游动物群落功能的原地影响尚未在该地区进行。使用基于功能特征的方法，我们发现P。东海水华显着改变了东海近岸海域浮游动物的群落结构和功能。浮游动物物种丰富度和生物多样性在水华后增加。根据体长、摄食类型、营养群和繁殖方式，我们将浮游动物分为四个功能类群并表征其动态。水华前后，浮游动物群落以桡足类和被囊类为代表的草食性和自由产卵谱系为主，而水华期间，浮游动物群落以小水母、毛颌类和桡足类为代表的肉食性和卵孵谱系为主。
Blooms of the non-toxic dinoflagellateProrocentrum donghaienseare common in the East China Sea; however, thein situimpacts of these blooms on zooplankton community functions have not yet been conducted in this area. Using functional trait-based methods, we found thatP. donghaiensebloom significantly changed the zooplankton community structure and functions in the coastal water of the East China Sea. Zooplankton species richness and biodiversity increased after the bloom. Based on body length, feeding type, trophic group and reproductive mode, we categorized zooplankton into four functional groups and characterized their dynamics. Before and after the bloom, the zooplankton community was dominated by herbivorous- and free-spawner- lineages represented by copepods and tunicates, while during the bloom, the zooplankton community was dominated by carnivorous- and egg-brooding- lineages represented by small jellyfish, chaetognaths and copepods.
