Impact of the fear effect in a prey-predator model incorporating a prey refuge

作者:

Highlights:

• A prey-predator model incorporating fear factor is developed.

• A globally stable theorem of coexistence equilibrium is established.

• The existences of Hopf bifurcation and limit cycle are shown.

• The fear effect can not only reduce the population density of predator, but also stabilize the system by excluding the existence of periodic solutions.
