Relationship between the proportion of total holobiont citrate synthase (CS) activity that is symbiont-derived (RSym) and the contribution of symbiont biomass (measured as protein) to the total holobiont biomass (1-ß, see Muscatine et al., 1981) in (A) a natural population of Exaiptasia pallida and (B) two groups of E. pallida re-infected with either Symbiodinium type A4 or Symbiodinium minutum. The dotted line in (A) describes y = x. The solid lines describe the actual relationship between RSym and 1-ß in each group of animals, and are statistically significant at p < 0.001.
