Bet-hedging strategies in expanding populations
Fig 3
The asymptotic mean velocity increases with k in temporally varying environments.
(A) Velocities obtained by numerical integration of Eq 5 for sa = 0.75, ss = 1, sb = 3 (yellow dot of Fig 2) for different switching rates k shown in the figure legend. (B) The same for sa = 0.25, ss = 1, sb = 2 (blue dot of Fig 2). In (A), the optimal strategy is α = 1 for all k values. In (B), bet-hedging optimal strategies appear depending on the value of k. The continuous red and yellow lines (both in A and B) illustrate analytical predictions under the two limits vM(k → 0) = (va(α) + vb(α))/2 and , respectively.
