Fig. 3: Predictability of fitness effects by community composition.
From: Mutualism reduces the severity of gene disruptions in predictable ways across microbial communities
A Distributions of 2001 bootstrapped R2 values for Additive, Strongest, and Average models in predicting mutant fitness in 3-species communities under mutualistic (left) and competitive (right) conditions. B The number of genes for which both E and M caused a significant main effect in mutualism, categorized by whether the interaction term was non-significant (additive—left) or significant (non-additive—right). The non-additive bar was colored by the number of genes in which the fitness was higher (positive—white) or lower (negative—black) than expected from additivity.
