Figure 2From: Dynamics of a delayed phytoplankton-zooplankton system with Crowley-Martin functional response The global attractivity of system ( 4 ). (a)-(b) Time series. (c) Phase portrait. The parameters and initial values are the same as given in Figure 1. Numerical simulations show that for system (4) the positive equilibrium point \(E^{*}\) has global attractivity when \(\tau=2.5\).Back to article page
