Short summary
Here we investigate how CO2 enrichment affects the relationships light–production and light–calcification in coral reef communities. For the three communities tested, CO2 did not affect the light–production relationships, while calcification was lower at elevated CO2 for all light levels. Our result indicates that CO2 can modify the balance between net calcification and net photosynthesis of reef communities by depressing community calcification without affecting community photosynthesis.
