Abstract:
This paper is concerned with a stochastic ratio‐dependent predator‐prey model with varible coefficients. By the comparison theorem of stochastic equations and the Itô formula, the global existence of a unique positive solution of the ratio‐dependent model is obtained. Besides, some results are established such as the stochastically ultimate boundedness and stochastic permanence for this model.
