Coral bleaching, reef fish community phase shifts and the resilience of coral reefs

By Web Admin on 10/31/2006 | Keyword(s): Coral reef resources

The 1998 coral bleaching event, the largest coral reef disturbance on historic record, caused dramatic habitat loss. Annual censuses that spanned both before and after the bleaching event (from 1993 to 2004) in the central Great Barrier Reef were reported here. The authors found no difference in species richness, diversity (H’), and total abundance over the 12 year period, providing results contrary to other long-term studies. These results demonstrate the difficulty in measuring coral reef resilience and the need for accurate metrics. Authors: David R. Bellwood, Andrew S. Hoey, John L. Ackerman, Martin Depczynski. Global Change Biology 12: 1587-1594
