Complex Dynamics of a Diffusive Holling-Tanner Predator-Prey Model with the Allee Effect
Figure 3
The phase portrait of model (7) with the strong Allee effect. The parameters are taken as , , , and . is an unstable node point; is saddle point; the positive equilibrium is a cusp point. In this case, the point is globally asymptotically stable. The dotted curves are the nullclines.
