Figure 5. Variability in fitness over time.

(A) Box plots summarizing population mean fitness over time for each evolution condition (columns) in each assay environment (rows). Line, box, and whiskers represent the median, quartiles, and data within 1.5 × IQR (interquartile range), respectively; outlier populations beyond whiskers are shown as points. (B) IQR from box plots in (A) are plotted as a function of time for each evolution condition and assay environment. IQR for fitness measured in home and away environments are represented by solid and dashed lines, respectively. Error bars represent 95 % confidence intervals of IQR calculated from bootstrapped replicate fitness measurements.

Brown–Forsythe test p values for paired comparisons of fitness variance in home environment and away environment for populations evolved in each evolution condition (columns). White boxes correspond to invalid self-comparisons. p values represent a one-sided test in which the alternative hypothesis is that home variance is less than away variance. 0 < p < 0.05 (blue) indicates home variance significantly less than away variance. 0.95 ≤ p < 1 (red) indicates home variance significantly greater than away variance.
