Wetlands, especially Wetlands of International Importance (Ramsar sites), are of significance to provide habitats, food sources and gathering grounds for waterfowl to molt, rest, winter and nest. And the importance degrees of wetlands are heterogeneo

Abstract In this paper, we consider a stochastic SIR epidemic model with regime switching. The Markov semigroup theory will be employed to obtain the existence of a unique stable stationary distribution. We prove that, if Rs0 $\mathcal{R}^{s}>0$ and

In this paper, we consider a stochastic SIRS epidemic model with seasonal variation and saturated incidence. Firstly, we obtain the threshold of stochastic system which determines whether the epidemic occurs or not. Secondly, we prove that there is a

We introduce stochasticity into a multigroup SIR model with nonlinear incidence. We prove that when the intensity of white noise is small, the solution of stochastic system converges weakly to a singular measure (i.e., a distribution) if ℛ0≤1 and
