| Abstract: | This paper considers the sufficient conditions of persistence and extiction for a nonautonomous Ayala system without diffusion and with diffusion. Further, if it is a periodic system, under appropriate conditions it can have a strictly positive periodic solution which is globally asymptotically stable. |
