利用2014年夏季南海中部海域的资料，评价了小摆线桡足类与水文因子、浮游植物和浮游鱼的关系。属丰度在6.00 ~ 93.75 ind.m−3之间，高丰度带出现在南海季风急流分支。该带地表水温度较低、盐度较高，表明深水入侵是该属聚集的有利因素。该属的群落结构以松唇蜜桃（oithona plumiferaa5）为主，相似香唇蜜桃占与松唇蜜桃相关的属丰度的97%。db-RDA分析结果表明，温度、Chla、幼鱼和鱼卵对该属的群落结构都有影响，温度是最重要的限制因素。GAMs分析结果表明，o的丰度。鱼和桡足动物受Chla、幼鱼和鱼卵的影响；丰富ofO。相似的是受鳕鱼产卵的影响；和丰富的o。白羽鱼受到幼鱼和幼鱼的影响。因此，我们认为夏季南海季风急流分支和深水入侵有利于南海中部浮游生物的聚集。我们证实，温度是热带海域oithoni属鱼类繁殖的限制因素，而oithoni属是南海中部初级生产和幼鱼之间的食物网连接者。
The relationships between the small cyclopoid copepodOithonaand hydrological factors, phytoplankton and ichthyoplankton were evaluated using the data obtained in the central South China Sea (SCS) in summer 2014. The genus abundance ranged from 6.00 ind. m−3to 93.75 ind. m−3with high abundance band occurring in the branch of SCS Monsoon Jet. The lower temperature and higher salinity in the surface water of the band than other zones indicated that deep water intrusion was a positive factor for aggregation of the genus. The community structure of the genus was dominated byOithona plumiferaandOithona similismade up 97% of the genus abundance associated withOithona tenuis. The result of db-RDA analysis showed that the community structure of the genus was affected by temperature, Chla, larval fishes and fish spawns, and temperature was the most important limiting factor. The result of GAMs analysis showed that abundance ofO.tenuis, and copepodites were affected by Chla, larval fishes and fish spawns; abundance ofO.similiswas affected by Chlaand fish spawns; and abundance ofO.plumiferawas affected by Chlaand larval fishes. Therefore, we suggest that the branch of SCS Monsoon Jet and deep water intrusion favor aggregation of plankton in the central SCS in summer. We confirm that the temperature is the limiting factor to the reproduction of the genusOithonain tropic seas and the genusOithonais a food-web linker between primary production and larval fishes in the central SCS.
