Increasing growth rate slows adaptation when genotypes compete for diffusing resources

Fig 4

Selection decreases when growth rates are higher in a spatially-structured environment.

A) Simulation design with a faster growing mutant (green) in the midst of evenly spaced ancestors. In these simulations, ζ increased only by increasing the natural length scale, which is equivalent to increasing growth rate (μ1). B) The absolute increase in frequency of the mutant genotype as a function of ζ.
