A Fitness of ancestor- (grey), monoculture- (orange) and co-culture- evolved (red) L. plantarum when paired with coevolved S. cerevisiae in growth media with high or low amounts of glucose. L. plantarum strains are labelled with their experimental treatment and position in the microplate. For example, M2D is a monoculture-evolved L. plantarum population from microplate well 2D, and C5A is a co-culture-evolved L. plantarum population from microplate well 5A. B Amount of glucose remaining in spent media of ancestral-, monoculture- and co-culture-evolved L. plantarum and S. cerevisiae cultures after 48 hours. The relationship between the strength of coexistence with (C) fitness difference (R2 = 0.48, p < 1 × 10−4) and (D) niche difference for L. plantarum and S. cerevisiae pairwise communities (R2 = 0.085, p = 0.021). All error bars represent standard deviation. Orange dots represent monoculture-evolved L. plantarum strains, red dots represent co-culture-evolved L. plantarum strains.
