Water Column Productivity and Temperature Predict Coral Reef Regeneration Across the Indo-Pacific
Predicted increases in seawater temperatures accelerate coral reef decline due to mortality by heat-driven coral bleaching. Alteration of the natural nutrient environment of reef corals reduces tolerance of corals to heat and light stress and thus will exacerbate impacts of global warming on reefs....
