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

Figure 17

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