珊瑚对气候变化的抵抗力与包括异养能力和能量储备在内的生理参数有关。最近，珊瑚相关微生物群落的潜在灵活性和多样性也与珊瑚健康和对环境压力的抵抗力有关。本研究使用美国夏威夷的O 'Escene岛作为自然实验室，探索四种珊瑚物种（Porites compressa，Porites lobata，Pocillopora acuta和Pocillopora meandrina）在自然海洋条件梯度中微生物群落组成的变化。此外，我们评估了珊瑚相关的微生物群落的组成与珊瑚生理之间的潜在关系。我们发现，微生物群落组成不同的所有珊瑚物种之间，以及在几个物种内的采集点。微生物群落组装似乎是由确定性和随机过程相结合，这些社区的组成更经常与珊瑚生理学的测量比环境参数之间的收集网站。具体而言，珊瑚的脂质和蛋白质水平，珊瑚能量储备的两个组成部分，解释了显着的微生物群落组成inPorites lobata和Pocillopora acuta，分别。此外，微生物群落多样性下降的比例贡献的异养相对于光合自养的珊瑚组织中增加inPorites compressaandPocillopora acuta，但相反的是真实的为Porites裂叶。这些研究结果表明，如果珊瑚异养随着海洋变暖而增加，它可能与某些珊瑚物种中微生物群落多样性的变化同时发生，这可能是由于光合产物的产生减少和/或粘液层营养成分的变化。总的来说，能源储备和异养的连接表明珊瑚资源的使用在塑造珊瑚相关的微生物群落的组成在一系列自然海洋条件下的作用，这种关系可能是重要的，因为一些珊瑚适应全球气候变化。
The resistance of corals to a changing climate has been linked to physiological parameters including heterotrophic capacity and energy reserves. Recently, the potential flexibility and diversity of coral-associated microbial communities have also been related to coral health and resistance to environmental stress. This study uses the island of O‘ahu in Hawai‘i, USA, as a natural laboratory to explore variability in the microbial community composition of four coral species (Porites compressa,Porites lobata,Pocillopora acuta, andPocillopora meandrina) across a gradient of natural ocean conditions. In addition, we assessed potential relationships between the composition of coral-associated microbial communities with coral physiology. We found that microbial community composition differed among all coral species, as well as among several of the collection sites within species. Microbial community assembly appeared to be governed by a combination of deterministic and stochastic processes, and the composition of these communities was more often related to measurements of coral physiology than environmental parameters among the collection sites. Specifically, coral lipid and protein levels, two components of coral energy reserves, explained significant portions of microbial community composition inPorites lobataandPocillopora acuta, respectively. Further, microbial community diversity decreased as the proportionate contribution of heterotrophy relative to photoautotrophy in coral tissues increased inPorites compressaandPocillopora acuta, but the opposite was true forPorites lobata. These findings suggest that if coral heterotrophy increases with warming oceans, it could co-occur with shifts in microbial community diversity in some coral species, possibly from decreased production of photosynthates and/or changes in the nutritional makeup of the mucus layer. Overall, connections with energy reserves and heterotrophy suggest a role for coral resource use in shaping the composition of coral-associated microbial communities across a range of natural ocean conditions, a relationship that may be important as some corals acclimatize to global climate change.
