Reef corals bleach to resist stress
Marine Pollution Bulletin, 2009A rationale is presented here for a primary role of bleaching in regulation of the coral-zooxanthellae symbiosis under conditions of stress. Corals and zooxanthellae have fundamentally different metabolic rates, requiring active homeostasis to limit zooxanthellae production and manage translocated products to maintain the symbiosis.

Reef corals bleach to survive change
Nature, 2001The bleaching of coral reefs, in which symbiotic algae are lost from reef-building invertebrates, is usually considered to be a drastic and damaging response to adverse environmental conditions1,2. Here I report results from transplant experiments involving different combinations of coral host and algal symbiont that support an alternative view, in ...

Coral bleaching: thermal adaptation in reef coral symbionts.
Nature, 2004Many corals bleach as a result of increased seawater temperature, which causes them to lose their vital symbiotic algae (Symbiodinium spp.) - unless these symbioses are able to adapt to global warming, bleaching threatens coral reefs worldwide. Here I show that some corals have adapted to higher temperatures, at least in part, by hosting specifically ...
