Broad-sense heritability (H²) values and the 95% confidence interval for the estimate of heritability of calcification rate for each of the eight Hawaiian coral species tested (all are significant, p < 0.05).

Pocillopora acuta	0.58	0.29–0.87	0.975	0.717	5.61
P. meandrina	0.55	0.33–0.77	0.629	0.521	5.73
Montipora capitata	0.52	0.31–0.76	1.341	1.219	5.93
M. patula	0.36	0.16–0.63	0.435	0.776	5.86
M. flabellata	0.44	0.16–0.80	2.742	3.497	5.87
Porites compressa	0.61	0.41–0.81	1.684	1.069	6
P. evermanni	0.32	0.11–0.60	0.443	0.959	5.46
P. lobata	0.39	0.18–0.65	0.826	1.319	5.93

Treatment pH and collection location were set as covariates (see Table S2 for a comparison of results using other combinations of covariates). Additional columns correspond to estimates of genotypic variance, environmental variance, and the effective number of replicates from ANOVA results as outlined in the text.
