Figure 3.

The ecological impact of a t-Sry release campaign depending on release rates μ_std for different polyandry scenarios (coloured lines, ψ = [0, 0.2, 0.4, 0.6, 0.8, 1]) as measured by (a) the maximum population size during a release campaign (N_max), (b) the equilibrium number of reproductive females after 100 months, (c) the time to eradication, and (d) the absolute number of drive males released. The coloured dots on the top of panels (c,d) denote the minimal release effort required for population eradication ${\mu }_{\mathrm{std}}^{\star }$. The carrying capacity K was assumed to be 1000 and drive male sperm competitiveness was r = 0.2 (as typically observed empirically). Remaining parameter values for all panels: s = 0.9, b = 4, m₁ = 1.
