报告摘要：Two stochastic population models will be introduced. For a stochastic single-species population model with Allee effect, we derive the corresponding Fokker-Planck equation and obtained the SPD. By analyzing the shape of SPD under different parameter conditions, we find that the P-bifurcation may occur in the stochastic model. For a predator-prey model of Leslie type with generalized Holling type III functional response, the phenomenon of noise-induced oscillatory transitions is studied. To reveal the probabilistic mechanisms of the noise-induced transitions, we construct the confidence domains of stochastic attractors by applying the technique of stochastic sensitivity functions.
