Noise-Induced Transitions in a Population Growth Model Based on Size-Dependent Carrying Capacity

Figure 4

The stationary mean value of the population size ⟨𝑋⟩ versus the noise amplitude 𝑎. The system parameter values are 𝐾₀=100, 𝜖=0.03, 𝛾=10⁻⁵, 𝛼=0.5, and 𝜈=75. Note the jump of the mean population size ⟨𝑋⟩ at the critical value of the noise amplitude, 𝑎_𝑐≈0.66.
