Reduced heterotrophy in the stony coral Galaxea fascicularis after life-long exposure to elevated carbon dioxide
Ocean acidification imposes many physiological, energetic, structural and ecological challenges to stony corals. While some corals may increase autotrophy under ocean acidification, another potential mechanism to alleviate some of the adverse effects on their physiology is to increase heterotrophy....
