Coral-algal physiology
Corals showed a significantly lower photochemical efficiency (Fv/Fm)
after exposure to the heat treatment (Supplemental Fig. 1.A, t = 4.37,
df = 5.94, p-value < 0.005). GP:R ratios also decreased,
although the mean difference was not statistically significant
(Supplemental Fig. 1.B, t = 2.31, df = 3.39, p = 0.09). There were no
visual signs of paling or bleaching of coral nubbins during the
experiment.
