Statistical results for the interval estimate and significance of temperature, pH and temperature–pH combined on the physiology (photosynthesis, respiration and calcification rates) for the corals A. palmata (native to outer-reef), P. asteoides (native to outer-reef) and P. astreoides (native to seagrass), under both high and low experimental treatment variance. For each of the metabolic parameters (photosynthesis, respiration and calcification) model estimates are shown for different variable interactions (species, habitat, treatment variance, temperature and pH). Models were simplified to remove any non-significant parameters (see the electronic supplementary material). Confidence intervals (CIs) are indicated at 95% for the model estimates as are significance (p) values. Experimental parameters represented in the model are indicated by dummy-coding.
