1. Area-normalized responses of P
Area-normalized responses of P. verrucosa to incubations under factorial combinations of temperature and PCO2, based on trials conducted in 2014 and 2015.
Area-normalized responses of P. verrucosa to incubations under factorial combinations of temperature and PCO2, based on trials conducted in 2014 and Trials were conducted at 26.5 versus 29.7°C and at ambient (∼400 µatm) versus high (∼1000 µatm) PCO2, and values are plotted as a function of size (tissue surface area). (A,B) Calcification, (C,D) respiration and (E,F) gross photosynthesis. Each symbol represents the results from one coral colony, and the lines show the fitted partial regression coefficients from the linear mixed-effects model (Table 3). A flat relationship was expected if colony size did not affect the physiological performance of individual modules (polyps). Sample sizes in Trial 1: N=8 for all treatment combinations; in Trial 2: N=12 in LT-AC and HT-AC, N=8 in LT-HC and N=11 in HT-HC.
