Remote coral reefs are thought to be more resilient to climate change due to their isolation from local stressors like fishing and pollution. We tested this hypothesis by measuring the relationship between local human influence and coral community resilience. Surprisingly, we found no relationship between human influence and resistance to disturbance and some evidence that areas with greater human development may recover from disturbance faster than their more isolated counterparts. Our results suggest remote coral reefs are imperiled by climate change, like so many other geographically isolated ecosystems, and are unlikely to serve as effective biodiversity arks. Only drastic and rapid cuts in greenhouse gas emissions will ensure coral survival. Our results also indicate that some reefs close to large human populations were relatively resilient. Focusing research and conservation resources on these more accessible locations has the potential to provide new insights and maximize conservation outcomes.

偏远不会增强珊瑚礁的恢复力

偏远的珊瑚礁被认为更能适应气候变化，因为它们与捕鱼和污染等当地压力因素隔绝。我们通过测量当地人类影响与珊瑚群落恢复力之间的关系来检验这一假设。令人惊讶的是，我们发现人类影响与抗扰之间没有关系，而且一些证据表明人类发展程度更高的地区可能比更孤立的地区更快地从干扰中恢复过来。我们的研究结果表明，与许多其他地理上孤立的生态系统一样，偏远的珊瑚礁受到气候变化的威胁，不太可能成为有效的生物多样性方舟。只有大幅和迅速减少温室气体排放才能确保珊瑚的生存。我们的结果还表明，一些靠近大量人口的珊瑚礁相对有弹性。
