Ocean acidification and warming reduce juvenile survival of the fluted giant clam, Tridacna squamosa
Anthropogenic carbon dioxide (CO2) emissions are causing ocean acidification and ocean warming; however, the synergistic effects of these stressors on giant clams are completely unknown. Juveniles of the fluted giant clam, Tridacna squamosa Lamarck, 1819, were exposed to present-day control seawater...
