Role of constant prey refuge on stage structure predator–prey model with ratio dependent functional response

作者:

Highlights:

• A stage structured predator–prey model with ratio-dependent functional response and a constant prey refuge is studied.

• Conditions for uniform persistence and global stability have been obtained by constructing suitable Lyapunov function.

• Qualitative analysis is supported by numerical simulations.

• The study shows that constant prey refuge plays an important role on the coexistence of predator–prey species.
