Endozoicomonas correlates with growth and disease. Phylogenetic independent contrast in Endozoicomonas relative abundance in coral tissue (per 1000 reads), correlated against (A) contrast in microbial dominance in coral tissue (assessed by Simpson’s Index), (B) constrast in coral disease susceptibility (estimated from integrated long-term coral disease prevalence data) and (C) coral growth rate (mm per year) from the Coral Traits Database. Dotted red lines in panels A-C indicate the null expectation that if traits are uncorrelated, change in the x-axis trait will not correlate with changes in the y-axis trait, with contrasts instead distributed equally above or below the dotted line. Statistics from phylogenetic generalized least squares (PGLS) regression for A-C are available in Supplemental Data Tables 5 and 9. (D) Modeled strength and direction of causality between Endozoicomonas relative abundance, disease susceptibility and growth rate during coral evolution using both Brownian Motion (blue) and Pagel’s Lambda (green, dotted) evolutionary models. The thickness of the lines represents the averaged standardized path coefficients of the top competing models based on CICc values (Supplementary Data Table S11)
