珊瑚礁正日益经历从珊瑚占主导地位到大型藻类占主导地位的转变。尽管人们越来越了解珊瑚礁食草动物在控制藻类方面的功能作用,但确定食草动物与大型藻类关系中可能的临界点仍然是一个挑战。评估任何珊瑚礁生态系统相对于珊瑚到大型藻类临界点的位置对于了解复原力特性、预测状态转变和制定有效的管理实践至关重要。我们在法属波利尼西亚莫雷阿岛进行了多年的现场实验来估计这些特性。虽然我们发现大型藻类逃脱控制的尖锐食草阈值,但珊瑚鱼的食草性环境水平远高于防止大型藻类增殖所需的水平。这些发现与之前观察到的莫雷阿岛前礁的高恢复力是一致的。我们的方法可以识别脆弱的珊瑚礁系统,迫切需要采取管理行动,以防止向大型藻类的转变并保护恢复力所必需的特性。
Coral reefs increasingly are undergoing transitions from coral to macroalgal dominance. Although the functional roles of reef herbivores in controlling algae are becoming better understood, identifying possible tipping points in the herbivory-macroalgae relationships has remained a challenge. Assessment of where any coral reef ecosystem lies in relation to the coral-to-macroalgae tipping point is fundamental to understanding resilience properties, forecasting state shifts, and developing effective management practices. We conducted a multi-year field experiment in Moorea, French Polynesia to estimate these properties. While we found a sharp herbivory threshold where macroalgae escape control, ambient levels of herbivory by reef fishes were well above that needed to prevent proliferation of macroalgae. These findings are consistent with previously observed high resilience of the fore reef in Moorea. Our approach can identify vulnerable coral reef systems in urgent need of management action to both forestall shifts to macroalgae and preserve properties essential for resilience.
