Description

The effect of light and PCO2 on the calcification and survival of Pocillopora damicornis recruits settled from larvae
released in southern Taiwan was tested.

These data include the counts of surviving larvae for each light treatment in each of the tanks over the duration of the experiment.

These data were published in Aaron M Dufault, Aaron Ninokawa, Lorenzo Bramanti, Vivian R Cumbo, Tung-Yung Fan, Peter J Edmunds (2013) The role of light in mediating the effects of ocean acidification on coral calcification. Journal of Experimental Biology 216: 1570-1577. doi:10.1242/jeb.080549

Methods & Sampling

In March 2011and June 2012, recruits were incubated at 31, 41, 70, 122 and 226 µmol photons m-2 s-1 under ambient (493 µatm) and high PCO2 (878 µatm). After 5 days, calcification was measured gravimetrically and survivorship estimated as the number of living recruits.

Survival was assessed daily throughout the experiment by photographing the tiles with a digital camera (10 megapixel, Canon 40d) fitted with a macro lens. Live coral tissue was readily seen in the images, and presence of the tissue was used to categorize corals as alive or dead.

Replicate corallites were pooled within treatments and log-rank tests (Machin et al., 2006) were used to test for differential survival among light and PCO2 treatments. All statistical analyses were conducted using JMP software (version 9.0.2, SAS Institute Inc.).

Data Processing Description

BCO-DMO processing notes:

- added conventional header with dataset name, PI name, version date, reference information
- added lab, lat, lon, expt columns
- changed values in expt 2 treatment_light from percent to integers to match expt. 1
- for expt 2, filled in count_1 to count_4 with nd
- sorted by expt, treatment_pCO2, tank, treatment_light, tile
