From: Lineage-specific symbionts mediate differential coral responses to thermal stress
Photosynthetic efficiency of P. damicornis subjected to thermal stress. a Diurnal oscillations in the maximum (Fv/Fm) and effective (∆F/Fm') quantum yield of PSII charge separation. b Changes in PSII adjustment to thermal stress (∆Qm). Values are means ± standard error (n = 9). Asterisks (*) indicate significant difference between control and thermal stress at designated time points (Tukey’s post hoc test, p < 0.05)
