Short summary
We investigated the physiological responses of a green tide alga to the combination of ocean acidification and nutrient limitation. Elevated pCO2 did not affect the growth rate when cultured under nutrient replete conditions but reduced it under P limitation. P limitation resulted in a larger inhibition in growth for sporelings compared to adult plants. These findings indicate that ocean acidification and nutrient limitation may hinder the occurrence of green tides in future ocean environment.
