Dynamics analysis of a reaction-diffusion system with Beddington-DeAngelis functional response and strong Allee effect

In this paper, the dynamics of a diffusive predator-prey model with modified Leslie-Gower term and strong Allee effect on prey under homogeneous Neumann boundary condition is considered. Firstly, we obtain the qualitative properties of the system including the existence of the global positive solution and the local and global asymptotical stability of the constant equilibria. In addition, we investigate a priori estimate and the nonexistence of nonconstant positive steady state solutions. Finally, we establish the existence and local structure of steady state patterns and time-periodic patterns for the system. (C) 2019 Elsevier Ltd. All rights reserved.
