Dynamics of a stochastic Holling II one-predator two-prey system with jumps

•We consider a stochastic Holling II one-predator two-prey model with jumps.•The sufficient conditions for the extinction and persistence of the solution are established.•We analyze how the jump noise affects the population dynamics.

In this paper, a stochastic Holling II one-predator two-prey system with jumps is investigated. Firstly, the properties of the solution, such as the existence and uniqueness of the global positive solution, stochastic ultimate boundedness and the pathwise estimation are studied. Then we mainly establish the sufficient conditions for the extinction and persistence in the mean of the solution. Results show that positive jump noise is advantageous to the system while negative jump noise is disadvantageous. Finally, a numerical example is introduced to illustrate the results.
