Allee effect, as one of the research hotspots in ecology and conservation biology, extremely easily affects distribution population space, especially for low-density population. In ecosystem, spatial predator is more vulnerable to effect since density always smaller than that prey, but relevant attention paid it few. this paper, we establish analyze a predator–prey system incorporating on Theoretically, use multi-scale analysis derive amplitude equation obtain different Turing patterns under intensities effect. Numerically, verify theoretical results. We also find growth rate significantly inhibited time reaching equilibrium tends be slower with increase intensity within certain limits. More interestingly, discovered extent stable although may lead complex dynamic behaviors. Our results help better understand species invasion nature ecology.
