The dynamics of predator-prey models with the Beddington-DeAngelis functional response are analyzed, primarily from the viewpoint of permanence (uniform persistence). The Beddington-DeAngelis functional response is similar to the Holling type 2 functional response but contains an extra term describi

✦ Synopsis
In this paper, a predator-prey system with Beddington-De Angelis functional response and diffusion is considered. First, we study qualitative properties of solutions to this reaction-diffusion system. Then, by ,zsing topological degree, we establish the existence of the nonconstant positive steady-states.

In this paper, a predator-prey system with Beddington-DeAngelis functional response is studied, where the predator preys on n competing preys. We prove that the system admits very rich dynamics, including permanence, ultimate boundedness, extinction. Moreover, under some appropriate assumptions, the
Stochastically asymptotic stability in the large of a predator-prey system with Beddington-DeAngelis functional response with stochastic perturbation is considered. The result shows that if the positive equilibrium of the deterministic system is globally stable, then the stochastic model will preser
