Genotypic variations in mean coral aragonite: seawater KDSr/Ca in individual colonies of Porites spp. following >5 months of acclimation to 198, 416 and 750 μatm3 pCO2 at 25 °C.
Within each pCO2 treatment, different letters indicate significant differences between genotypes (p < 0.05; ANOVA and Tukey post-hoc). Error bars represent the combined 95% confidence limits of seawater and skeletal Sr/Ca measurements.
