Pleistocene Perspectives on Coral Reef Community Structure1
Center for Tropical Paleoecology, Smithsonian Tropical Research Institute Apartado 2072, Balboa, Republic of Panama
Composition and zonation of coral reef communities are unstable on the scale of human lifetimes, but stable on average over thousands to hundreds of thousands of years. Traditional small-scale ecological studies can miss community patterns which are obscured by the noise of short-term change. Tests for stability require monitoring of populations over many generationsmillenia for long-lived corals and forest trees. The only recourse is the fossil record.
