Using a quantitative genetics approach, the proportion of the variance in thermal tolerance traits that has a genetic basis (i.e. heritability) was estimated as a proxy for their adaptive potential in the widespread Indo-Pacific reef-building coral Acropora millepora. Two physiologically different populations that associate respectively with one thermotolerant (Symbiodinium clade D) and one less tolerant symbiont type (Symbiodinium C2) were chosen.Pulse amplitude modulated (PAM) fluorometry and high performance liquid chromatography (HPLC) analysis was used to assess photosynthesis and photoprotective pigment profile. Quantitative real-time polymerase chain reaction (qRT-PCR) assays were used to assass changes in expression of fundamental stress genes. To estimate the potential of corals to adapt to rising seawater temperatures. Site locations:Nelly Bay (Magnetic Island), Orpheus Island
