Scaling the Effects of Ocean Acidification on Coral Growth and Coral-Coral Competition on Coral Community Recovery
Ocean acidification (OA) is negatively affecting calcification in a wide variety of marine organisms. These effects are acute for many tropical scleractinian corals under short-term experimental conditions, but it is unclear how these effects interact with ecological processes, such as competition f...

Ocean acidification (OA) is negatively affecting calcification in a wide variety of marine organisms.

This study sought to test the use of individual-based models (IBMs) as a tool to scale up the effects of OA recorded in short-term studies to community-scale impacts, combining data from field surveys and mesocosm experiments to parameterize an IBM of coral community recovery on the fore reef of Moorea, French Polynesia.
