Community Change and Evidence For Variable Warm-Water Temperature Adaptation Of Corals In Northern Male Atoll, Maldives

This study is a descriptive analysis of coral reef communities in North Male, Maldives seven years after the major 1998 coral bleaching event with the goal of evaluating ongoing changes and ability for adaptation. The study looked at coral community composition, recruitment community, evidence for recovery and responses to corals to a subsequent thermal anomaly in 2005. Eleven shallow reef areas consisting of hard calcium carbonate were assessed using benthic field measurements and bleaching surveys. Maldivian coral recovery showed considerable spatial and taxonomic variability, with dominant taxa characterized by stress tolerance and several previously common taxa now still quite rare. Compared to other Indian Ocean islands, the Maldivian coral response was considerably more variable and complicated. The authors conclude that natural selective processes are in progress with responses showing potential for adaptation.
