Protection zone in a diffusive predator-prey model with Beddington-DeAngelis functional response.
In any reaction-diffusion system of predator-prey models, the population densities of species are determined by the interactions between them, together with the influences from the spatial environments surrounding them. Generally, the prey species would die out when their birth rate is too low, the habitat size is too small, the predator grows too fast, or the predation pressure is too high. To...
متن کاملSpatial Pattern Formation of a Modified Leslie-Gower Predator-Prey Model Incorporating Prey Refuge
In this paper, the spatiotemporal dynamics of a modified Leslie-Gower predator-prey system with Beddington DeAngelis functional response incorporating constant proportion of prey refuge under homogeneous Neumann boundary condition is investigated. The local and global asymptotic stability of the unique positive homogeneous steady state in the absence of diffusion are discussed. Furthermore, we ...
متن کاملExistence of Periodic Solutions in a Discrete Predator-Prey System with Beddington-DeAngelis Functional Responses
A discrete predator-prey model with Holling II and Beddington-DeAngelis functional responses is investigated. With the aid of differential equations with piecewise constant arguments, a discrete version of continuous nonautonomous delayed predator-prey model with BeddingtonDeAngelis functional responses is proposed. By using Gaines andMawhin’s continuation theorem of coincidence degree theory, ...
متن کاملGlobal boundedness of solutions in a reaction–diffusion system of Beddington–DeAngelis-type predator–prey model with nonlinear prey-taxis and random diffusion
In this paper, a reaction–diffusion system of a predator–prey model with Beddington–DeAngelis functional response is considered. This model describes a prey-taxis mechanism that is an immediate movement of the predator u in response to a change of the prey v (which leads to the collection of u). We use some approaches to prove the global existence-boundedness of classical solutions and overcome...
متن کاملDynamics of a stochastic non-autonomous predator-prey system with Beddington-DeAngelis functional response
A stochastic non-autonomous predator-prey system with Beddington-DeAngelis functional response is proposed, the existence of a global positive solution and stochastically ultimate boundedness are derived. Sufficient conditions for extinction, non-persistence in the mean, weak persistence in the mean and strong persistence in the mean are established. The global attractiveness of the solution is...
