在西澳大利亚宁加洛珊瑚礁的珊瑚群产卵之前和之后，对与三种珊瑚物种（细角鹿角珊瑚、达米角角珊瑚和福克内里管珊瑚）相关的细菌进行了评估。在大规模产卵事件之前和之后对每个物种的两个菌落进行了采样，并在平生后为 P. damicornis 收集了另外两个样本。选择 16 S rRNA 基因的 470 bp 可变区域进行焦磷酸测序，以了解珊瑚相关细菌多样性和群落结构的潜在变化。根据 Chao1 多样性指标评估，所有珊瑚物种产卵后的细菌多样性均有所增加。在纲水平上观察到群落结构的微小变化，并且纳入 PCA 分析的属分类水平数据表明，尽管产卵后细菌多样性增加，但根据物种分组的样本，与珊瑚相关的群落结构并没有发生很大变化。然而，可以从数据集中检测到有趣的变化；例如，珊瑚产卵后，α-变形菌门的相对丰度增加，特别是玫瑰杆菌分支在所有珊瑚物种中都很突出，表明该菌群可能对珊瑚繁殖很重要。
Bacteria associated with three coral species, Acropora tenuis, Pocillopora damicornis and Tubastrea faulkneri, were assessed before and after coral mass spawning on Ningaloo Reef in Western Australia. Two colonies of each species were sampled before and after the mass spawning event and two additional samples were collected for P. damicornis after planulation. A variable 470 bp region of the 16 S rRNA gene was selected for pyrosequencing to provide an understanding of potential variations in coral-associated bacterial diversity and community structure. Bacterial diversity increased for all coral species after spawning as assessed by Chao1 diversity indicators. Minimal changes in community structure were observed at the class level and data at the taxonomical level of genus incorporated into a PCA analysis indicated that despite bacterial diversity increasing after spawning, coral-associated community structure did not shift greatly with samples grouped according to species. However, interesting changes could be detected from the dataset; for example, α-Proteobacteria increased in relative abundance after coral spawning and particularly the Roseobacter clade was found to be prominent in all coral species, indicating that this group may be important in coral reproduction.
