Figure 4. Metabolic efficiency and the rate of growth in five environments.

Figure 4

The maximum growth rate was measured for the sample of 48 strains and used to rank strains within each environment. Black points represent growth ranks averaged over 5 environments, with a regression line with a slope of 0.00005 which is statistically indistinguishable from being flat (t = 0.221, df = 46, P = 0.826).
