珊瑚礁的动态性质为研究生态系统对气候变化造成的破坏的反应提供了难得的机会。 1998年，大堡礁经历了大范围的珊瑚白化和死亡。结果，隐底栖鱼类群落经历了戏剧性的相变。 13 年过去了，在 96 代鱼之后，隐底栖鱼类群仍未恢复到漂白前的形态。尽管珊瑚丰度恢复到或超过漂白前的值，但情况仍然如此。漂白后的鱼群没有表现出恢复的迹象。如果这些寿命较短的鱼类是寿命较长的鱼类的模型，他们认为（1）1998年白化事件对长寿鱼类种群的全面影响尚未显现，（2）可能需要几十年或更长时间，这些长寿物种才能开始恢复或再生，（3）尽管珊瑚回归，鱼类种群可能无法恢复到以前的组成。
The dynamic nature of coral reefs offers a rare opportunity to examine the response of ecosystems to disruption due to climate change. In 1998, the Great Barrier Reef experienced widespread coral bleaching and mortality. As a result, cryptobenthic fish assemblages underwent a dramatic phase-shift. Thirteen years, and up to 96 fish generations later, the cryptobenthic fish assemblage has not returned to its pre-bleach configuration. This is despite coral abundances returning to, or exceeding, pre-bleach values. The post-bleach fish assemblage exhibits no evidence of recovery. If these short-lived fish species are a model for their longer-lived counterparts, they suggest that (1) the full effects of the 1998 bleaching event on long-lived fish populations have yet to be seen, (2) it may take decades, or more, before recovery or regeneration of these long-lived species will begin, and (3) fish assemblages may not recover to their previous composition despite the return of corals.
