Permanence for a delayed discrete ratio-dependent predator-prey model with monotonic functional responses. (English) Zbl 1167.34359
Summary: A delayed discrete ratio-dependent predator-prey model with monotonic functional responses is proposed. By applying the comparison theorem of difference equation, sufficient conditions are obtained for the permanence of the system.
