Pairwise invasibility plots for different density-compensation strategies b in eqs. 1,2,3.

The plots show the fitness (eq. 7) of an invading strategy with a density-compensation strategy along the vertical axis for residents with density-compensation strategies along the horizontal axis. Plus and minus signs indicate strategy combinations resulting in positive and negative invasion fitness, respectively; in addition, regions of negative invasion fitness are shaded. Vertical dashed lines show the critical b-values of the resident. Small insets in the top left of each plot show areas of mutual invasibility. Parameters: r = 5 (MSS), r = 40 (Hassell), r = 0.5 (Ricker), and d = 0.05 Different intrinsic growth rates r were chosen to obtain a similar growth response for similar b-values across the three models.
