Figure 1. Plots of the values of mortality and net calcification rates for each average pH_TS value of each site and for each transplantation period for the three coral species.

The acidity is indicated by the different colours: red (Site 4 - pH_TS 7.40), yellow (Site 3 - pH_TS 7.74), green (Site 2 - pH_TS 7.87), blue (Site 1 - pH_TS 8.07). Each transplantation period is denoted by the average seawater temperature. Average values = height of the histogram bars; median = cross, 10–90 percentiles intervals = error bars. Empty bins in the histograms indicate missing data due to storms that swept away the experiments. (A) Mortality rates (% month⁻¹). Polyp mortality rate for B. europaea, L. pruvoti, and A. calycularis and coenosarc-polyp tissue mortality for the latter. For B. europaea and L. pruvoti at 15.7 °C and 16.2 °C and for the latter also at 23.5 °C the cross symbols indicate zero mortality. (B) Net calcification rates (mg CaCO₃ g⁻¹ month⁻¹) for B. europaea, L. pruvoti, and A. calycularis.
