Varying r–K relationships among genotypes across different ranges of r in each of the nine environments.

(a)–(i) Each panel shows r–K relationships in one environment labeled on the top of the panel. Each dot shows the average r and average K from a bin of 500 genotypes grouped by r. The same vertical black line is shown on all panels, the position of which is determined by the average r of the group with the highest K among the nine environments. Note that the y-axes of different panels are not directly comparable because of the variation in the amount of resource among media.
