Correlations. Multivariate correlation analyses were run on both the physiological and molecular data, and the four strongest associations were selected for plotting. There were statistically significant, negative correlations between cell-specific chlorophyll a (chl-a) concentration and Symbiodinium density (a), as well as between Symbiodinium photosystem I (psI, subunit III) mRNA expression and the maximum dark-adapted quantum yield of photosystem II (; (b)). There were statistically significant, globally positive correlations between Symbiodinium psI and phosphoglycolate phosphatase (pgpase) gene expression (c), as well as between Symbiodinium ascorbate peroxidase (apx1) and pgpase gene expression (d). In all cases, correlations were assessed across the dataset as a whole, and the global correlations are represented by solid black lines that span the entire panel. Individual correlations were then assessed within each site of origin and temperature treatment, and the corals from Houbihu exposed to a variable and stable temperature regime are denoted by black diamonds and squares, respectively. The Houbihu variable and stable temperature regime trend lines are dotted and solid black, respectively. Similarly, the corals from Houwan exposed to a variable and stable temperature regime are denoted by grey diamonds and squares, respectively, and are associated with grey dotted and grey solid trend lines, respectively. When a statistically significant difference between slopes of two temperature treatments within a site was documented with ANCOVA (), an asterisk () was placed next to one of the two trend lines. When a statistically significant difference between slopes of two sites within a temperature treatment was documented with ANCOVA (), a “#” was placed next to one of the two trend lines.
