Calcification Moderates the Increased Susceptibility to UV Radiation of the Coccolithophorid Gephryocapsa oceanica Grown under Elevated CO 2 Concentration: Evidence Based on Calcified and Non-calcified Cells
The physiological performance of calcified and non-calcified cells of Gephyrocapsa oceanica (NIES-1318) and their short-term responses to UV radiation were compared for cultures grown under present-day (LC, 400 μatm) and high pCO (HC, 1000 μatm) conditions. Similar growth rates and F /F values were...

| description | The physiological performance of calcified and non-calcified cells of Gephyrocapsa oceanica (NIES-1318) and their short-term responses to UV radiation were compared for cultures grown under present-day (LC, 400 μatm) and high pCO
(HC, 1000 μatm) conditions. Similar growth rates and F
/F
values were observed in both types of cell under LC conditions, indicating that the loss of calcification in the non-calcified cells did not lead to a competitive disadvantage under such conditions. Detrimental effects of elevated pCO
were observed in both cell types, with the growth rate of non-calcified cells decreasing more markedly, which might reflect a negative impact of higher cytoplasmic H
. When exposed to short-term UV radiation, similar trends in effective quantum yield were observed in both cell types acclimated to LC conditions. Elevated pCO
and associated seawater chemical changes strongly reduced effective quantum yield in non-calcified cells but no significant influence was observed in calcified cells. Based on these findings and comparisons with previous studies, we suggest that the negative impact of elevated cytoplasmic H
would exacerbate the detrimental effects of UV radiation while the possession of calcification attenuated this influence. |
