Abstract

: The variability of the species composition and community structure of coral ectosymbiotic invertebrates was studied using the reef-building coral Pocillopora verrucosa sampled from Dongsha Atoll (the northernmost atoll of the South China Sea). Overall, we discovered 61 symbiotic species, comprising 17 specialized obligate species and 44 generalists (facultative species and species with uncertain status). The total species richness, mean species number and mean abundance per colony were significantly higher in the lagoon than in the forereef, likely due to their respective temperature regimes. The lagoon is characterized by more frequent thermal anomalies than the forereef is, causing greater coral bleaching. This higher frequency of thermal stress apparently results in frequent renovations of coral-symbiotic communities following post-bleaching coral re-covery, which seem to be associated with the increased diversity of commensal fauna and, particularly, with the abundance of facultative symbionts. symbiotic communities from different environments of an isolated atoll: reef lagoon versus forereef // Invert.

孤立环礁不同环境下的珊瑚共生群落:礁湖与前礁

以南海最北环礁东沙环礁的造礁珊瑚为研究对象，研究了珊瑚外共生无脊椎动物物种组成和群落结构的变异。共发现61种，其中专门性种17种，通用性种44种(兼性种和状态不确定种)。泻湖的总物种丰富度、平均物种数量和平均每群落丰度均显著高于前礁，这可能与它们各自的温度制度有关。泻湖的特点是比前礁更频繁的热异常，造成更大的珊瑚白化。这种高频率的热应力显然导致珊瑚白化后恢复后珊瑚共生群落的频繁更新，这似乎与共生动物群的多样性增加有关，特别是与兼性共生体的丰富有关。孤立环礁不同环境的共生群落:礁湖与前礁// Invert。黑旋风。Vol.19。第一。p.78 - 90。doi: 10.15298 / invertzool.19.1.08

期刊介绍： Scientific peer-reviewed journal INVERTEBRATE ZOOLOGY publishes original papers, reviews and brief communications on morphology, anatomy, embryology, taxonomy, phylogeny, and ecology of any group of invertebrates from protistans to lower chordates. INVERTEBRATE ZOOLOGY accepts manuscripts in English or Russian and publishes them in printed and electronic versions. The Russian translations of English titles, abstracts and figure captions of the papers written by non-Russian authors can be provided by the editors. Invertebrate Zoology invites authors to publish extended monographic manuscripts after usual reviewing procedure. The monographic manuscripts can include up to 400 thousand letters and be prepared in English or in Russian. Accepted monographic manuscripts will have priority to be published in the nearest issue of the journal.
