Fig. 2 — (Color figure online) Selection for $V_{2}$ in the presence of a fitness cost. Time series of proportion of $V_{2}$ under moderate self-regulated SD, $σ_{S} = 0.4$ (and with $σ_{M} = 0$ ), are shown for $0 %$ fitness cost ( $β_{2} = β_{1}$ , black), $5 %$ fitness cost ( $β_{2} = 0.95 β_{1}$ , blue), $10 %$ fitness cost ( $β_{2} = 0.9 β_{1}$ , red), and $15 %$ fitness cost ( $β_{2} = 0.85 β_{1}$ , green), for a scale-free and b spatial networks. All the other parameters are as in Fig. 1
