Properties in Stage-Structured Population Models with Deterministic and Stochastic Resource Growth

Figure 15

Resource dynamics of semichemostat, logistic, semilogistic, and threshold-logistic growth rate at steady state w.r.t. harvesting rate. The grey trajectories show the resource density from different simulations for the stochastic case. The yellow curve represents the resource mean value of the simulations. The light blue curves represent the interval of standard deviation (68%) of resource density. The black curve represents the resource for the deterministic case.
