| Ruffled | Early | 0.786 (0.061) | 0.036 (0.001) | 0.70 (0.037) |
| Wrinkly | Early | 1.057 (0.022) | 0.039 (0.006) | 1.03 (0.025) |
| Studded | Late | 0.993 (0.012) | 0.045 (0.002) | 1.45 (0.048) |

Vmax is maximum growth rate of a single ecotype grown in 3% GMM (Methods). A one-way ANOVA and post hoc Tukey's HSD tests were used to determine significant differences between means (P < 0.05, n = 6). Numbers in parentheses are SEs.
1
Absorbance of Crystal Violet extracted from biofilm, 600 nm.
2
Absorbance of bacterial monoculture, 600 nm.
3
Swimming radius (cm).
