Effects of a Fluctuating Carrying Capacity on the Generalized Malthus-Verhulst Model

Figure 4

The plot of 𝐾₀⁻¹⟨𝑥(𝑡)⟩_∞ as function of the noise intensity 𝜎. The values of the parameters are 𝛾=0.8, 𝜇=0.5, and 𝑟=1. In this case, 𝛾𝜇=0.4<2𝑟 and, for 𝜎∼1, the number of individuals decreases with an infinite slope.
