Fig. 1: Relationship between in situ photosynthetic efficiency (F_v/F_m) and in situ mean seawater temperature for Acropora spp. and P. verrucosa.

The transparent points represent coral colonies. Bright colored points represent the mean and error bars show the standard error of the mean (s.e.m). Lines denote the thermal performance curve estimated by the Sharpe-Schoofield model and the shadow area around the fitting line is the 95% confidence interval estimated using bootstrapping method. The number of experiments included were n_P.verrucosa = 12 and n_{Acropora spp.} = 7. The number of biological replicates included in each experiment is given in Supplementary Table 6.
