Abstract
In this paper, we consider a discrete-time prey–predator model with a strong Allee effect. At first, applying the center manifold reduction, we discuss the topological structure of orbits near each fixed point, including hyperbolic one and non-hyperbolic one. Then, we apply the center manifold reduction to prove that the model undergoes fold bifurcation and transcritical bifurcation. At last, by the numerical analysis, we illustrate our results and find that the model possesses heteroclinic orbits in the first quadrant. Furthermore, we present a stable 7-periodic orbit and a stable 8-periodic orbit on the invariant cycle produced from the Neimark–Sacker bifurcation.
