Table 2 The effect of trait-lethal mutations is very strong

From: Trade-offs drive resource specialization and the gradual establishment of ecotypes

  1. The degree of specialization is much lower and niche breadth is much higher when mutation can only increase or decrease resource affinity by 0.1. n t is the mean of 20 simulations ± std. dev. N =1000, μ=0.05. aWithout trait-lethals. bWith trait-lethals.
