This paper is concerned with a delay Lotka-Volterra model under regime switching diffusion in random environment. Permanence and asymptotic estimations of solutions are investigated by virtue of V-function technique, M-matrix method, and Chebyshev's inequality. Finally, an example is given to illustrate the main results.

In this paper, we investigate a stochastic Gilpin–Ayala competition system, which is more general and more realistic than the classical Lotka–Volterra competition system. We reveal that the environmental noise will not only suppress a potential population explosion in the stochastic delay Gilpin–Ayala competition system but also make the solutions stochastically ultimately bounded. Comparing the classical Lotka–Volterra with Gilpin–Ayala competition system, we find that the latter has better proprieties.

This paper is concerned with a delay logistical model under regime switching diffusion in random environment. By using generalized Itô formula, Gronwall's inequality, and Young's inequality, some sufficient conditions for existence of global positive solutions and stochastically ultimate boundedness are obtained, respectively. Also, the relationships between the stochastic permanence and extinction as well as asymptotic estimations of solutions are investigated by virtue ofV-function technique,M-matrix method, and Chebyshev's inequality. Finally, an example is given to illustrate the main results.
