Figure 2From: Bifurcation and chaos in a discrete Holling–Tanner model with Beddington–DeAngelis functional responsePhase portraits corresponding to Fig. 2(a) and (b). (a)Quasi-periodic orbits for \(h=18.5\). (b) Period-10 orbits for \(h=19.7\). (c) Quasi-periodic orbits \(h=20\). (d) A chaotic attractor for \(h=21\)Back to article page
