Fig. 18 — Final sizes versus SD levels: the model in (1–1c) is used to quantify the amount of final sizes for $V_{1}$ (a), $V_{2}$ (b), and both (c), for different levels of SD strategies ( $σ_{M}$ and $σ_{S}$ ). The parameter values are $β = 0.5$ , $γ = 0.1$ , and for initial condition we have $y_{10} = 0.05$ and $y_{20} = 0.0001$ , thus $\frac{y_{20}}{y_{10}} = 0.002$
