Dynamics of a stochastic predator–prey system with Beddington–DeAngelis functional response

摘要

Some dynamical properties of a stochastic non-autonomous predator–prey system with Beddington–DeAngelis functional response are studied. Firstly, we show the existence, the uniqueness and the positivity of the solution. Secondly, we study the boundedness of moments and the upper-growth rate of the solution. Then we investigate the global attractivity of the system. Finally we introduce some figures to illustrate our main results.
