This study provides a descriptive analysis of the North Male, Maldives seven years after the 1998 bleaching disturbance to determine the state of the coral community composition, the recruitment community, evidence for recovery, and adaptation to thermal stress. Overall, hard coral cover recovered at a rate commonly reported in the literature but with high spatial variability and shifts in taxonomic composition. Massive Porites, Pavona, Synarea, and Goniopora were unusually common in both the recruit and adult communities. Coral recruitment was low and some coral taxa, namely Tubipora, Seriatopora, and Stylophora, were rarer than expected. A study of the bleaching response to a thermal anomaly in 2005 indicated that some taxa, including Leptoria, Platygyra, Favites, Fungia, Hydnophora, and Galaxea astreata, bleached as predicted while others, including Acropora, Pocillopora, branching Porites, Montipora, Stylophora, and Alveopora, bleached less than predicted. This indicates variable-adaptation potentials among the taxa and considerable potential for ecological reorganization of the coral community.
本研究对马尔代夫北马累环礁在 1998 年白化干扰后的七年进行了描述性分析，以确定珊瑚群落组成、补充群落的状态、恢复证据以及对热应激的适应情况。总的来说，硬珊瑚覆盖率的恢复速度与文献中常见的速度相当，但存在高度的空间变异性和分类组成的变化。块状多孔螅、扁脑珊瑚、拟滨珊瑚和陀螺珊瑚在补充和成年群落中都异常常见。珊瑚补充数量较少，一些珊瑚类群，如 Tubipora、Seriatopora 和 Stylophora，比预期的更为罕见。对 2005 年热异常下白化反应的研究表明，一些类群，包括 Leptoria、Platygyra、Favites、Fungia、Hydnophora 和 Galaxea astreata，如预测的那样白化，而其他类群，包括 Acropora、Pocillopora、分枝多孔螅、鹿角珊瑚、石珊瑚和 Alveopora，白化程度低于预测。这表明了各分类群之间存在不同的适应潜力，珊瑚群落的生态重组具有很大的潜力。
