Recent large-scale analyses suggest that local management actions may not protect coral reefs from climate change, yet most local threat-reduction strategies have not been tested experimentally. We show that removing coral predators is a common local action used by managers across the world, and that removing the corallivorous snail Coralliophila abbreviata from Caribbean brain corals (Pseudodiploria and Diploria species) before a major warming event increased coral resilience by reducing bleaching severity (resistance) and post-bleaching tissue mortality (recovery). Our results highlight the need for increased evaluation and identification of local interventions that improve coral reef resilience.
最近的大规模分析表明，局部管理措施可能无法保护珊瑚礁免受气候变化的影响，但大多数减少本地威胁的策略尚未经过实验测试。我们表明，去除珊瑚捕食者是世界各地管理者常用的一种常见的局部措施，在一次重大变暖事件之前，从加勒比海脑珊瑚（Pseudodiploria 和 Diploria 属）中去除珊瑚食螺 Coralliophila abbreviata，可以通过降低白化严重程度（抗性）和白化后组织死亡率（恢复力）来提高珊瑚的恢复力。我们的研究结果强调了需要增加对提高珊瑚礁恢复力的本地干预措施的评估和识别。
