Average (±1SE) total (μg cell−1) protein, carbohydrates and lipid content and cell volume for symbiont type C21a-A. millepora (a,e,i,m), C1-P. damicornis (b,f,j,n), C15-M. monasteriata (c,g,k,o) and S. trenchii-T. reniformis (d,h,l,p) at three pCO2 levels and 26.5 °C (light bars) or 31.5 °C (dark bars).
For each pane, the designations ‘temp’, ‘pCO2’ and ‘int’ indicate significant temperature, pCO2 or interactive effects (two-way ANOVA). If a pCO2 effect was observed, the letters indicate significant differences between pCO2 groups (n = 6). If an interactive effect was observed, the letters above each bar indicate significant differences among the 6 treatments.
