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

Figure 13

Impact on size structure of semichemostat, logistic, semilogistic, and threshold-logistic growth rate at steady state w.r.t. harvesting rate. The grey trajectories show the impact on size structure from different simulations for the stochastic case. The yellow curve represents the mean value of the simulations. The light blue curves represent the interval of standard deviation (68%). The black curve represents the impact on size structure for the deterministic case. Equation (17) is used to derive the above graphs.
