Figure 1From: The complex dynamics of a stochastic toxic-phytoplankton-zooplankton modelPhase portrait of model ( 1 ) with K=0.6, r=4, m=0.5, a=0.9, b=0.7, c=0.1, d=0.2. The horizontal axis is the phytoplankton population P and the vertical axis is the zooplankton population Z. E 0 =(0,0) and E 1 =(0.6,0) are saddle points, the equilibrium point E ∗ =(0.1429,0.5442) is globally asymptotically stable.Back to article page
