Comparison of regression models testing the effects of temperature (ambient: 25°C or hot: 32°C) and fish presence (fish or no fish) on <i>P</i>. <i>damicornis</i> photosynthetic efficiency (F_V/F_M), fitting the data through the means for colonies within treatments for the Acclimation and Stress experimental periods during the manipulative thermal bleaching experiment.

Akaike’s information criteria (AIC) and AIC differences (ΔAIC) were calculated per model selection practice [58–60]. See S8 Table for calculations with individual points yielding similar results as mean models (mean model results presented here).
