Versauerung der Meere
Ocean acidification (OA) is a particularly broad threat facing all coral reef ecosystems. Research has not yet evaluated the specific effects on MCEs and hermatypic scleractinian corals. If similar to shallow-water reefs, as a result of OA, MCEs could see reductions in net community calcification, reductions in coral growth, and likely shifts to algae-dominated systems with a few resistant scleractinian taxa.
