Figure 1

Adaptation and selection strength. (A) Change in fitness for each experimental line. Data are means for five replicate, paired fitness assays of the ancestor and the endpoint population of each line in its respective treatment. anc: black lines (all line 1), anc788: grey lines, solid grey: line 2, dashed grey: line 3, circles: harsh, triangles: benign. (B) Fitness of each ancestor relative to endpoint populations (n = 5). Data from benign environments are pooled, as are data from lines 2 and 3 for anc788 (within the H and B treatments). Bars are 95% confidence intervals from t-tests of mean differences between the harsh (H) and benign (B) treatments for each ancestor. (C) Mean selection coefficient of mutations in endpoint populations (n = 5). Data from benign environments are pooled, as are data from lines 2 and 3 for anc788 (within the H and B treatments). Bars are 95% confidence intervals from t-tests of mean differences between the harsh (H) and benign (B) treatments for each ancestor. (D) The change in fitness as a proportion of total fitness (n = 5). Data from benign environments are pooled, as are data from lines 2 and 3 for anc788 (within the H and B treatments). Bars are 95% confidence intervals from t-tests of mean differences between the harsh (H) and benign (B) treatments for each ancestor.
