Fig. 3.

Antioxidant activity measured in the host and symbiont components of (a–f) Acropora millepora and (g–l) Stylophora pistillata for the control (27 °C; white bars) and treatment (32 °C; red bars) over 14 days, including superoxide dismutase, total glutathione and catalase (or catalase-like activity in the symbiont). Host components normalised to mg^-1 of host protein and symbiont normalised to mg^-1 of symbiont protein. Asterisks indicate significant differences between treatments where *P < 0.05, **P < 0.01 and ***P < 0.001, and letters indicate significant differences at P < 0.05. Averages (± SE) are shown (n = 4–5)
