评估微型浮游动物和桡足类对微浮游动物的摄食压力是解决微生物食物网效率的关键要求。虽然微型浮游动物对微微浮游生物的捕食已被广泛研究，但很少有人比较微型浮游动物对异养细菌、聚球藻和微真核生物等不同类群的微浮游动物的影响。此外，在极少数现有的研究中，没有一致的证据表明桡足类对微浮游动物有促进或抑制作用。需要更多的研究来提高我们对微型浮游动物和桡足类对微浮游动物的影响的了解。稀释孵化和桡足类添加孵化是在2007年5月16-29日前往南黄海的邮轮上进行的。估计了微型浮游动物和中华哲水蚤对浮游植物、鞭毛虫和微微浮游动物的大量捕食。根据营养和生物学参数将站点划分为富营养化和少营养化。微浮游动物是中央少营养区微型浮游动物的主要食物，而浮游植物是沿海富营养区微型浮游动物的主要食物。在中央少营养区，微型浮游动物对聚球藻有较好的食性。加入桡足动物后，纤毛虫丰度下降，聚球藻类丰度增加(3个试验站分别为382%、和%)，表明微型浮游动物对聚球藻具有较强的捕食压力。我们的结果表明，聚球藻可能是南黄海低营养水域浮游食物网的重要碳源。
Assessment of microzooplankton and copepods grazing pressure on picoplankton is a key requirement for resolving the microbial food web efficiency. Although microzooplankton grazing on picoplankton has been extensively studied, the impact of microzooplankton on different groups of picoplankton, i.e., heterotrophic bacteria,Synechococcusand picoeukaryotes have rarely been compared. Furthermore, in the very few existing studies there is no consistent evidence of an enhancing or restraining effect of copepods on picoplankton. More studies are needed to improve our understanding of the influence of microzooplankton and copepod on picoplankton. Dilution incubations and copepod addition incubations were performed during a cruise to the southern Yellow Sea on May 16–29, 2007. The bulk grazing of microzooplankton and the calanoid copepodCalanus sinicuson phytoplankton, flagellates and picoplankton was estimated. Stations were divided into either eutrophic or oligotrophic according to the nutrient and biological parameters. Picoplankton comprised a large part of the diet of microzooplankton in the central oligotrophic area, while phytoplankton was the main food of microzooplankton in the coastal eutrophic area. In the central oligotrophic area, microzooplankton preferred grazing onSynechococcus. After copepod addition, ciliate abundance decreased whileSynechococcusabundance increased (382%, 64% and 64% at three experimental stations, respectively), indicating strong grazing pressure of microzooplankton onSynechococcus. Our results suggest thatSynechococcusmight be an essential carbon source the planktonic food web in the oligotrophic waters of southern Yellow Sea.
