The role of light in mediating the effects of ocean acidification on coral calcification
We tested the effect of light and P CO 2 on the calcification and survival of Pocillopora damicornis recruits settled from larvae released in southern Taiwan. In March 2011, recruits were incubated at 31, 41, 70, 122 and 226 μmol photons m−2 s−1 under ambient (493 μatm) and high P CO 2 (878 μatm). A...

We tested the effect of light and P CO 2 on the calcification and survival of Pocillopora damicornis recruits settled from larvae released in southern Taiwan. In March 2011, recruits were incubated at 31, 41, 70, 122 and 226 μmol photons m−2 s−1 under ambient (493 μatm) and high P CO 2 (878 μatm). After 5 days, calcification was measured gravimetrically and survivorship estimated as the number of living recruits. Calcification was affected by the interaction of P CO 2 with light, and at 493 μatm P CO 2 the response to light intensity resembled a positive parabola. At 878 μatm P CO 2 , the effect of light on calcification differed from that observed at 493 μatm P CO 2 , with the result that there were large differences in calcification between 493 μatm and 878 μatm P CO 2 at intermediate light intensities ( ca . 70 μmol photons m−2 s−1), but similar rates of calcification at the highest and lowest light intensities. Survivorship was affected by light and P CO 2 , and was highest at 122 μmol photons m−2 s−1 in both P CO 2 treatments, but was unrelated to calcification. In June 2012 the experiment was repeated, and again the results suggested that exposure to high P CO 2 decreased calcification of P. damicornis recruits at intermediate light intensities, but not at lower or higher intensities. Together, our findings demonstrate that the effect of P CO 2 on coral recruits can be light dependent, with inhibitory effects of high P CO 2 on calcification at intermediate light intensities that disappear at both higher and lower light intensities. |
