Asymmetrical Impact of Allee Effect on a Discrete-Time Predator-Prey System

Figure 3

The trajectories of the prey and predator population described by model (1) ((a1) and (b1)), model (11) ((a2) and (b2)), and model (24) ((a3) and (b3)). Parameter values: (a1–a3): 𝑟=0.7, 𝛼=0.05, 𝛽=0.6, 𝐾=100; 𝑢₁=𝑢₂=5,𝑥₀=25, and 𝑦₀=15; (b1–b3): 𝑟=3, 𝛼=0.04, 𝛽=0.04, 𝐾=100, 𝑢₁=𝑢₂=8, 𝑥₀=30, and 𝑦₀=20.
