Coral resistance to ocean acidification linked to increased calcium at the site of calcification
International audience Ocean acidification threatens the persistence of biogenic calcium carbonate (CaCO 3) production on coral reefs. However, some coral genera show resistance to declines in seawater pH, potentially achieved by modulating the chemistry of the fluid where calcification occurs. We u...
