An N-species ratio-dependent predator-prey food-chain model with distributed time delays is investigated. It is shown that the system is permanent under some appropriate conditions, and sufficient conditions are obtained for the global attractivity of the positive equilibrium of the system.
- Distributed time delay
- Global attractivity
- Uniform persistence
