Intraspecific diversity and ecological zonation in coral-algal symbiosis.

Proceedings of the National Academy of Sciences of the United States of America - 28 Mar 1995

Rowan R, Knowlton N

Abstract excerpt

All reef-building corals are obligately associated with photosynthetic microalgal endosymbionts called zooxanthellae. Zooxanthella taxonomy has emphasized differences between species of hosts, but the possibility of ecologically significant zooxanthella diversity within hosts has been the subject of speculation for decades. Analysis of two dominant Caribbean corals showed that each associates with three taxa of...
