With the help of a continuation theorem based on Gaines and Mawhin's coincidence degree, easily verifiable criteria are established for the global existence of positive periodic solutions of a delayed ratio-dependent predator-prey system in a periodic environment.

By using a fixed point theorem and Lyapunov functional, an especially easily checked criterion is obtained for the global existence and global asymptotic stability of positive periodic solutions of a periodic predator-prey system with infinite delays. Moreover, the global existence theorem is also s
For the predator-prey system with distributed delay, when the distributed delay kernel is the general Gamma distributed delay kernel, the existence and the stability of periodic solution are obtained by using the linear chain trick and geometric singular perturbation theory. ~) 2005 Elsevier Ltd.

This paper concerns the local and global dynamical properties of the nonnegative and positive equilibria of a Lotka-Volterra predator-prey system with distributed delays. It is shown that, while the positive equilibrium does not exist, the nonnegative equilibrium is globally asymptotically stable or
