Figure 6.
Loss of mutualism in the backward (recovery) direction for network A. Shown are, for six values of ζ, the steady state species abundances versus κ as it decreases from high value for which the deterministic network system is in the extinction state. The value of the critical noise amplitude ζc is approximately the same as that obtained from the forward process in figure 5. The initial conditions are chosen randomly from the basin of the low abundance steady state. Other parameter values are the same as those in figure 5.
