Abstract

In this paper, we investigate the dynamics of a discrete commensal symbiosis model with Holling type functional response and density dependent birth rate. Sufficient conditions are obtained for the permanence, partial extinction, and global attractivity of the system. Our analysis presents that the density dependent birth rate plays a crucial role on the dynamic behaviors of the system. Finally, numerical simulations and graphical illustrations are given to indicate the analytical results. [ABSTRACT FROM AUTHOR]

Abstract

We study A two species discrete competitive system with Beddington-DeAngelis functional response in this paper. Sufficient conditions which guarantee the extinction of a species and the global attractivity of the other one are obtained. Our results supplement some existing ones. [ABSTRACT FROM AUTHOR]
