为了确定类群对海洋酸化 (OA) 敏感和抵抗的特性，我们测试了这样的假设：珊瑚礁钙化者对 OA 的敏感性不同，这是由显着特征决定的功能群联盟的可预测结果。我们对比了八种珊瑚和八种钙化藻类的功能群，这些功能群是根据珊瑚和藻类的形态、珊瑚的骨骼结构、藻类钙化的空间位置以及珊瑚和藻类的生长速度来定义的。钙化对OA的反应与珊瑚的形态和骨骼结构无关；然而，它们受到珊瑚和藻类生长速度（快速钙化器比慢速钙化器更敏感）以及藻类钙化部位和形态的影响。以快速生长为特征的物种组合，以及藻类的细胞壁钙化，可能会成为未来海洋中的生态损失者。这种相对成功的转变将影响物种的相对和绝对丰度以及珊瑚礁提供的商品和服务。
To identify the properties of taxa sensitive and resistant to ocean acidification (OA), we tested the hypothesis that coral reef calcifiers differ in their sensitivity to OA as predictable outcomes of functional group alliances determined by conspicuous traits. We contrasted functional groups of eight corals and eight calcifying algae defined by morphology in corals and algae, skeletal structure in corals, spatial location of calcification in algae, and growth rate in corals and algae. The responses of calcification to OA were unrelated to morphology and skeletal structure in corals; they were, however, affected by growth rate in corals and algae (fast calcifiers were more sensitive than slow calcifiers), and by the site of calcification and morphology in algae. Species assemblages characterized by fast growth, and for algae, also cell-wall calcification, are likely to be ecological losers in the future ocean. This shift in relative success will affect the relative and absolute species abundances as well as the goods and services provided by coral reefs.
