Guan, Xiaona; Wang, Weiming; Cai, Yongli Spatiotemporal dynamics of a Leslie-Gower predator-prey model incorporating a prey refuge. (English) Zbl 1225.49038 Nonlinear Anal., Real World Appl. 12, No. 4, 2385-2395 (2011). Summary: We investigate the spatiotemporal dynamics of a two-dimensional predator-prey model, which is based on a modified version of the Leslie-Gower scheme incorporating a prey refuge. We establish a Lyapunov function to prove the global stability of the equilibria with diffusion and determine the Turing space in the spatial domain. Furthermore, we perform a series of numerical simulations and find that the model dynamics exhibits complex Turing pattern replication: stripes, cold/hot spots-stripes coexistence and cold/hot spots patterns. The results indicate that the effect of the prey refuge for pattern formation is tremendous. This may enrich the dynamics of the effect of refuge on predator-prey systems.
