Figure 1.
Photos of representative coral fragments from (a) Acropora millepora, (b) Pocillopora damicornis, (c) Montipora monasteriata, and (d) Turbinaria reniformis.
Rectangles indicate subsamples taken from each fragment for lipid, protein/carbohydrate, and tissue biomass analyses. The remaining tissue was airbrushed for chlorophyll a and endosymbiont density measurements.
Table 1.
Average conditions for each of the 6 treatments representing three pCO2 levels at two temperature regimes (ambient, elevated = ambient + 2.5°C).
Figure 2.
Average daily calcification rate during the first and the second half of the experiment for (a, b) Acropora millepora, (c, d) Pocillopora damicornis, (e, f) Montipora monasteriata, and (g, h) Turbinaria reniformis.
Averages ± 1 SE are shown for three pCO2 levels and two temperature regimes (26.5, 29.0°C). Asterisks indicate significant differences between 26.5 and 29.0°C within a given pCO2 level (determined by a posteriori slice tests). The letters a and b indicate results of the post hoc Tukey tests when there was a significant pCO2 effect. Sample sizes ranged between 5 and 6. Statistical details can be found in Table S1.
Figure 3.
Average chlorophyll a concentrations and symbiont density for (a, b) Acropora millepora, (c, d) Pocillopora damicornis, (e, f) Montipora monasteriata, and (g, h) Turbinaria reniformis.
Averages ± 1 SE are shown for three pCO2 levels and two temperature regimes (26.5, 29.0°C). Asterisks indicate significant differences between 26.5 and 29.0°C within a specific pCO2 level (determined by a posteriori slice tests). The letters a and b indicate results of the post hoc Tukey tests when there was a significant pCO2 effect. Sample sizes ranged between 5 and 6. Statistical details can be found in Table S2.
Figure 4.
Average lipid, protein, carbohydrate concentrations, and tissue biomass of (a–d) Acropora millepora, (e–h) Pocillopora damicornis, (i–l) Montipora monasteriata, and (m–p) Turbinaria reniformis.
Averages ± 1 SE are shown for three pCO2 levels and two temperature regimes (26.5, 29.0°C). Asterisks indicate significant differences between 26.5 and 29.0°C within a specific pCO2 level (determined by a posteriori slice tests). The letters a and b indicate results of the post hoc Tukey tests when there was a significant pCO2 effect. Sample sizes ranged between 4 and 6. Statistical details can be found in Table S3.
