The Dynamics Of Tri-Trophic Food Web Model With Mixed Selection Of Functional Responses

Abstract

     In this paper, a tri-trophic food web model with mixed selection of functional responses is proposed and analyzed. It is assumed that, the food web system consisting of one prey and two predators, in which there is an explicit inter-specific competition between the two predators. Dynamical behavior of all possible equilibrium points has been investigated locally as well as globally. Sufficient conditions for the system to be uniformly persistent and / or extinction have been derived.
