Coral reefs are declining at an unprecedented rate as a consequence of local and global stressors. Using a 26-year monitoring database, we analyzed the loss and recovery dynamics of coral communities across seven islands and three archipelagos in French Polynesia. Reefs in the Society Islands recovered relatively quickly after disturbances, which was driven by the recovery of corals in the genus Pocillopora (84% of the total recovery). In contrast, reefs in the Tuamotu and Austral archipelagos recovered poorly or not at all. Across archipelagos, predation by crown-of-thorns starfish and destruction by cyclones outweighed the effects of heat stress events on coral mortality. Despite the apparently limited effect of temperature-mediated stressors, the homogenization of coral communities towards dominance of Pocillopora in the Society Archipelago and the failure to fully recover from disturbances in the other two archipelagos concern the resilience of Polynesian coral communities in the face of intensifying climate-driven stressors.
由于地方和全球压力的影响，珊瑚礁正以前所未有的速度减少。我们利用 26 年的监测数据库，分析了法属波利尼西亚七个岛屿和三个群岛的珊瑚群落的损失和恢复动态。社会群岛的珊瑚礁在受到干扰后恢复得相对较快，这是由 Pocillopora 属珊瑚的恢复所驱动的（占总恢复量的 84%）。相比之下，图阿莫图和澳拉罗亚群岛的珊瑚礁恢复得很差或根本没有恢复。在整个群岛中，棘冠海星的捕食和旋风的破坏超过了热应激事件对珊瑚死亡率的影响。尽管温度介导的压力源的影响显然有限，但珊瑚群落向社会群岛中 Pocillopora 的主导地位趋同，以及另外两个群岛无法从干扰中完全恢复，这令人担忧波利尼西亚珊瑚群落在面对日益加剧的气候驱动压力时的恢复力。
