Diurnally Fluctuating pCO 2 Modifies the Physiological Responses of Coral Recruits Under Ocean Acidification
Diurnal pCO(2) fluctuations have the potential to modulate the biological impact of ocean acidification (OA) on reef calcifiers, yet little is known about the physiological and biochemical responses of scleractinian corals to fluctuating carbonate chemistry under OA. Here, we exposed newly settled P...

Diurnal pCO(2) fluctuations have the potential to modulate the biological impact of ocean acidification (OA) on reef calcifiers, yet little is known about the physiological and biochemical responses of scleractinian corals to fluctuating carbonate chemistry under OA.
