Figure 2.

Changes in resource-competition traits relative to ancestors in seven different selection environments (A: ancestors, C: COMBO, L: light-limited, P: P-limited, N: N-limited, B: biotically depleted medium, S: high salt, BS: biotically depleted and high salt). Small circles are individual populations started from single clones (isoclonal), small triangles are the genotypically diverse populations. Large circles and error bars correspond to the average and standard error across replicate populations in each selection environment. Error bars on small points in a–d correspond to 95% confidence interval from non-parametric bootstrapping.
