(A) Illustration of the instantaneous growth rate depending on the environment. Both species have the same average reproduction rate ϕ1 = ϕ2 = ϕ but species 1 is more sensitive to environmental changes (ω1 > ω2) (B) Comparison of the IBM and the Langevin model. We show the fixation time for neutral evolution for x0 = 0.5 vs the environmental switching rate 1/τ. Dots correspond to the IBM [m = 0] for different values of 
in red, blue and green. Black lines are analytic solutions [Eq. (7) with Eq. (10)]. For quickly fluctuating environments both results are in good agreement whilst for large τ the white noise approximation fails. The gray line corresponds to the timescale of reproduction. Other parameters are as in Fig. 3.
