全球气候变化威胁着热带珊瑚礁，但当地管理可以影响复原力。虽然人为营养物的增加降低了珊瑚的抵抗力和恢复能力，但不知道自然营养物流的损失或恢复如何影响珊瑚礁的恢复。在这里，我们测试如何自然的海鸟来源的营养补贴，这是由入侵的老鼠的威胁，影响机制和模式的珊瑚礁恢复后，极端的海洋热浪使用多年的实地实验，重复调查，贝叶斯建模。从老鼠岛移植到海鸟岛的珊瑚迅速吸收了海鸟来源的营养，在3年内完全适应了新的营养条件。海鸟提供的营养增加，反过来又使珊瑚个体和整个珊瑚礁的生长速度翻了一番。海鸟还与鹿角珊瑚覆盖的更快恢复时间（<4年）和整个底栖生物群落更动态的恢复轨迹有关。我们的结论是，恢复海鸟种群和相关的营养途径，可以通过提高珊瑚的生长和恢复率，促进更大的珊瑚礁的恢复能力。海鸟为珊瑚礁提供营养，加速珊瑚在极端海洋热浪后的生长和恢复。
Global climate change threatens tropical coral reefs, yet local management can influence resilience. While increasing anthropogenic nutrients reduce coral resistance and recovery, it is unknown how the loss, or restoration, of natural nutrient flows affects reef recovery. Here, we test how natural seabird-derived nutrient subsidies, which are threatened by invasive rats, influence the mechanisms and patterns of reef recovery following an extreme marine heatwave using multiyear field experiments, repeated surveys, and Bayesian modeling. Corals transplanted from rat to seabird islands quickly assimilated seabird-derived nutrients, fully acclimating to new nutrient conditions within 3 years. Increased seabird-derived nutrients, in turn, caused a doubling of coral growth rates both within individuals and across entire reefs. Seabirds were also associated with faster recovery time of Acropora coral cover (<4 years) and more dynamic recovery trajectories of entire benthic communities. We conclude that restoring seabird populations and associated nutrient pathways may foster greater coral reef resilience through enhanced growth and recovery rates of corals. Seabirds provide nutrients to coral reefs that accelerate coral growth and recovery after an extreme marine heatwave.
