Temperature and general physiology of Acropora millepora and its symbionts under control (grey) and treatment (orange) conditions: (a) logged temperature in coral tanks over experimental period, (b) maximum (FV/FM) and effective (ΔF/FM′) quantum yield of PSII of coral colonies, (c) cell density at initial (T0), and final (TF) time points, (d) chlorophyll a and c2 per cell at T0 and TF, (e) density plot of single-cell FV/FM measurements of symbionts extracted from Acropora millepora colonies at TF. Data (b, c, d) represent mean values ± standard error, and dotted lines (a and e) indicate mean. Asterisks denote significant differences between control and treatment at * < 0.05, ** < 0.01, *** < 0.001.
