Figure 3. Box-plots representing the 25^th, 50^th and 75^th percentiles of ΔO₂, calculated from profiles measured within individuals (n = 2) prior (at 432 µatm) and during pCO₂ treatment incubations (432, 1141, 2151 µatm), under illumination (30 µmol photons m⁻² s⁻¹) for the six foraminiferal species.

Note the different scales between A) photosymbiotic and B) symbiont-free species. Outliers (>1.5 interquartile range) are indicated by circles.
