Figure 1. Oxygen evolution of cultured Symbiodinium clades (A, D) during 2 LD cycles at 24°C as presented in panels A and C (continues lines), followed by 2 cycles at 3 elevated temperatures (24°C, 27°C, 30°C), as presented in panels B and D (dashed lines).

White bars: light period; black bars: dark period; grey bars: subjective darkness. (A) clade A under LD; (B) clade A under LL; (C) clade C under LD; (D) clade C under LL. For each temperature, N = 4.
