Figure 3From: Dynamical analysis of a delayed food chain model with additive Allee effectPhase portraits of model (5.2) with fixed parameters given in (5.1) and different values of ρ; (a) stable focus for \(\rho =0.2\); (b) limit cycle for \(\rho =1\); (c) period-doubling for \(\rho =2\); (d) period-4 for \(\rho =4\); (e) period-8 for \(\rho =4.5\); (f) chaos for \(\rho =6\)Back to article page
