Figure 4From: Bifurcation and chaos in a discrete Holling–Tanner model with Beddington–DeAngelis functional responsePhase portraits corresponding to Fig. 3 (a) and (b). (a) Period-6 orbits for \(h=10\). (b) Period-12 orbits for \(h=9\). (c) An attracting invariant cycle for \(h=8\). (d) A chaotic attractor for \(h=4\)Back to article page
