Abstract

Over the last two centuries anthropogenic activity has elevated atmospheric CO₂, creating a greenhouse effect that is predicted to elevate global temperatures 1-4^o C within the century. Increases in surface temperature pose a threat to the world’s coral reefs and have been the cause of many mass bleaching events. To combat this new threat, corals must migrate, acclimate, or evolve to rising temperatures. Phenotypic plasticity, or the ability of an individual to express different phenotypes to survive in different environments, is crucial for sessile organisms since it can increase survivability in species incapable of moving to …
