Coral physiology in response to elevated temperatureSustained declines in photosynthetic health and symbiont density are well-defined characteristics of coral bleaching41. Consistent with previous studies10,11, the photosynthetic health of the coral symbionts, measured as dark-adapted quantum yield of PSII (FV/FM), decreased towards the end of the temperature ramping period (from day 4), declining further over the following three days (rmANOVA; F6,39 = 129.9, P  More
