Fig. 3. Multivariate analyses of coral traits.
Principal component analyses (PCA) on a matrix of physiological responses and isotope values in the coral Montipora capitata evaluating the influence of a season, b location, c symbiont community, and d depth-bin. Axis values in parentheses represent the proportion of total variance associated with the respective PC. Arrows represent significant (p < 0.05) correlation vectors for response variables; ellipses represent 90% point densities. See Table 1 for response metric details.
