Fig. 2: Physiology of Montipora capitata from Kāneʻohe Bay in December 2014 and June 2015.

Physiological measurements of Kāneʻohe Bay Montipora capitata experimental ramets in December 2014 (A–E) and June 2015 (F–J) for ramets that were originally non-bleached (solid gray bars) or bleached (open white bars) at the time of collection in November 2014. Mean (±1 SE) (A, F) endosymbiont cell density, (B, G) Contribution of Total carbon to Animal Respiration, CTAR, (C, H) calcification, and (D, I) tissue biomass, and (E, J) total lipids are shown for ramets that were kept in the Control (ambient seawater of pH 7.96 and unfed), Fed (ambient seawater of pH 7.96 and fed), OA (acidified seawater of pH 7.73 and unfed), and OA+Fed (acidified seawater pH 7.73 and fed) treatments. The dotted line in B and G indicates 100%. Sample sizes for each mean are indicated within each bar. Measurements were not made on ramets that were dead or nearly dead (i.e., <25% live tissue). Significant ANOVA main effects are listed in the top right corner of each panel. Letters indicate significant differences within each panel. Full ANOVA details are in Supplementary Table 3. The underlying data used to calculate CTAR (i.e., photosynthesis, respiration, feeding capacity, CZAR, and CHAR) are in Supplementary Fig. 4 and accompanying statistics are in Supplementary Table 4.
