Direction and Stability of Bifurcating Periodic Solutions in a Delay-Induced Ecoepidemiological System

Figure 4

Bifurcation diagram of the susceptible prey, infected prey and predator populations with respect to the delay 𝜏. Parameters are as in Figure 3(b). This figure shows that the coexisting equilibrium 𝐸^∗ is stable if 𝜏<𝜏₀=2.3187 and unstable if 𝜏>𝜏₀.
