Figure 1. Symbiodinium cell density, rate of net photosynthesis, and host-symbiont cooperation as a function of experimental treatment and time.
Symbiodinium cell density, expressed as cells per mg of host protein, rate of net photosynthesis, expressed as μg O2/cm2/min and the proportion of photosynthetically fixed carbon translocated to the host, calculated as the ratio of total radioactivity in DPM in host to holobiont tissue fractions of focal coral species (Amil: Acropora millepora, Maeq: Montipora aequituberculata, Gcol: Goniopora columna, Plob: Porites lobata, Gast: Galaxea astreata, Gacr: Galaxea acrhelia) representing different symbiont transmission modes (HT, horizontal transmitter, VT, vertical transmitter) under control (27 °C, blue circles) and elevated (31 °C, red triangles) temperature following 2, 4 and 17 days of treatment.
