为了评估潜在的珊瑚适应机制，我们调查了生理特性（生物量，脂质，蛋白质，叶绿素，和同位素营养策略代理）在八个夏威夷珊瑚物种沿着环境梯度的显着波高，海面温度，和海水叶绿素concentrations周围的岛屿的O'houi，夏威夷。我们使用珊瑚中表达的生理变化的量，以及可以通过环境变量解释的这种变化的比例，来构建关于每个物种适应或适应不同条件的相对能力的假设。属水平分析表明，Montipora和Pocilloporaphenotypes比Porites scorals受环境影响更大;种水平分析表明，Montipora capitata和Pocillopora acuta具有最宽的生理生态位边界，而Porites evermanni和Pocillopora meandrina则受到更大的生理限制。个体特征和环境梯度之间的相关性提供了对每个物种所采用的潜在适应机制的深入了解，这些机制使它们能够在Kāne 'ohe湾的珊瑚礁中持续存在，其中水流最低，温度，酸度和营养浓度相对于O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O'O潜在的适应机制包括（a）增加表面积与体积的比率，以促进更高的材料通量穿过扩散边界层和/或最大限度地收集光（M。Capitata和P. acuta），（B）代谢能量向能量储备的战略投资（Montipora和Pocillopora），（c）可能通过差异表达和功能改变蛋白质管理（Porites），和d）增加每个共生藻科细胞的叶绿素浓度以最大化光合作用（Porites compressa）。比较我们的结果与建立模式，这些物种的相对丰度周围O'ESTA表明，物种具有广泛的生理生态位边界，如M。CapitataandM.在预测的未来海洋条件下，flabellatamight可能会做得更好，并超越物种，如P。埃弗曼海峡meandrina，使它们成为珊瑚保护工作的潜在候选者。
To evaluate potential coral adaptive mechanisms, we investigated physiological traits (biomass, lipid, protein, chlorophyll, and isotopic proxies for trophic strategy) in eight Hawaiian corals species along an environmental gradient of significant wave height, sea surface temperature, and seawater chlorophyllaconcentration around the island of O‘ahu, Hawai‘i. We used the amount of physiological variation expressed in corals, and the proportion of this variation that could be explained by environmental variables, to construct hypotheses about the relative capacity for each species to adapt or acclimatize to differing conditions. Genus-level analyses indicated thatMontiporaandPocilloporaphenotypes are influenced more strongly by the environment thanPoritescorals.Species-level analyses revealed thatMontipora capitataandPocillopora acutahave the widest physiological niche boundaries, whereasPorites evermanniandPocillopora meandrinaare more physiologically restricted. Correlations between individual traits and the environmental gradient provided insight into potential adaptive mechanisms employed by each species that allow them to persist in reefs such as those within Kāne’ohe Bay, where water flow is lowest, and temperature, acidity, and nutrient concentrations are highest relative to other reefs around O‘ahu. Potential adaptive mechanisms included (a) increased surface-area-to-volume ratios to facilitate higher material flux across the diffusive boundary layer and/or to maximize light harvesting (M. capitataandP. acuta), (b) strategic investment of metabolic energy toward energy reserves (MontiporaandPocillopora), (c) changes in protein management likely via differential expression and function (Porites), and d) increased chlorophyll concentration per Symbiodiniaceae cell to maximize photosynthesis (Porites compressa). Comparison of our results with established patterns in the relative abundance of these species around O‘ahu suggests that species with wide physiological niche boundaries likeM. capitataandM. flabellatamight be expected to do better under predicted future ocean conditions and outcompete species such asP. evermanniandP. meandrina, making them potential candidates for coral conservation efforts.
