Electronic methods, results and figures from Resistance of corals and coralline algae to ocean acidification: physiological control of calcification under natural pH variability
Ocean acidification is a threat to the continued accretion of coral reefs, though some undergo daily fluctuations in pH exceeding declines predicted by 2100. We test whether exposure to greater pH variability enhances resistance to ocean acidification for the coral Goniopora sp. and coralline alga H...
