珊瑚礁受到自然干扰和局部和全球人为压力的破坏。随着压力的加剧，关于珊瑚礁在遭受重大破坏后是否会恢复的争论也在加剧。这场辩论的真正进展需要记录珊瑚组合在各种应力组合下的时间轨迹；因此，我们报告了小开曼岛珊瑚组合的相关变化。1999至2012年间，利用横断面、样方和最大直径测量，记录了海洋保护区内外的盖度、幼鱼密度和群落大小结构的时空格局。在五年多的时间里，漂白和疾病导致活保率从26%下降到14%，七年后完全恢复。幼鱼密度参差不齐，在2010年达到最大。这两种格局在保护区内外都是一致的。此外，优势珊瑚物种持续存在于保护区内外，尽管其大小和频率分布在时间和空间上各不相同。珊瑚群落的健康状况和不同保护级别反应的相似性表明，地方规模的人为干扰可以忽略不计，这是造成观察到的复原力的一个关键因素。
Coral reefs are damaged by natural disturbances and local and global anthropogenic stresses. As stresses intensify, so do debates about whether reefs will recover after significant damage. True headway in this debate requires documented temporal trajectories for coral assemblages subjected to various combinations of stresses; therefore, we report relevant changes in coral assemblages at Little Cayman Island. Between 1999 and 2012, spatiotemporal patterns in cover, densities of juveniles and size structure of assemblages were documented inside and outside marine protected areas using transects, quadrats and measurements of maximum diameters. Over five years, bleaching and disease caused live cover to decrease from 26% to 14%, with full recovery seven years later. Juvenile densities varied, reaching a maximum in 2010. Both patterns were consistent within and outside protected areas. In addition, dominant coral species persisted within and outside protected areas although their size frequency distributions varied temporally and spatially. The health of the coral assemblage and the similarity of responses across levels of protection suggested that negligible anthropogenic disturbance at the local scale was a key factor underlying the observed resilience.
