Coral Carbonic Anhydrases: Regulation by Ocean Acidification
Global change is a major threat to the oceans, as it implies temperature increase and acidification. Ocean acidification (OA) involving decreasing pH and changes in seawater carbonate chemistry challenges the capacity of corals to form their skeletons. Despite the large number of studies that have i...

Global change is a major threat to the oceans, as it implies temperature increase and acidification.
