Permanence and extinction for the stochastic plant–pollinator model with degenerate diffusion.

This paper investigates dynamical behaviors of a stochastic plant–pollinator model with degenerate diffusion. We derive a sufficient and almost necessary condition for the permanence and extinction for plant–pollinator model, which characterizes the long-time behavior of the dynamic systems. Examples and numerical results are provided to illustrate our findings. [ABSTRACT FROM AUTHOR]
