Bet-hedging strategies in expanding populations

Fig 5

The optimal strategy is robust with respect to noise induced by finite population size in temporally varying environments.

(A) Asymptotic mean velocities obtained by numerical integration of the stochastic Fisher Eq (10) for , s_s = 0.01, (yellow dot of Fig 2) and different population sizes. (B) The same for , s_s = 1, (blue dot of Fig 2). In both panels, the temporal switching rate of the environment is k = 0.001. Green dots corresponds to the results of Fig 3A and 3B for k = 0.001. Insets show a collapse of the curves according to Eq (11), with a fitted value of C = 3.
