Calcification and photophysiology responses to elevated pCO2 in six Halimeda species from contrasting irradiance environments on Little Cayman Island reefs

While elevated pCO2 associated with ocean acidification has been shown to lower calcification rates in some marine calcifiers, the modulating potential of irradiance is not well studied. Therefore, we examined the interactive effects of irradiance (high and low) and elevated pCO2 on six species of the macroalgal genus, Halimeda, an ecologically important tropical calcifier.
