Abstract

‎In prey-predator models‎, ‎nonlinear interaction between prey and predator populations results in oscillatory behavior that shows the dynamic growth of the populations‎. ‎In the growth process‎, ‎very often both prey and predator share the same resource in their habitat‎. ‎This is an intraguild predation model‎. ‎This study focuses on an intraguild prey-predator model generalized by introducing Holling type III functional response‎. ‎The existence of biologically meaningful equilibria has been investigated‎. ‎The stability analysis of the equilibria has been determined‎. ‎Finally‎, ‎bifurcation and numerical analyses have been presented to illustrate the dynamic behavior of the system‎. ‎Taking the {biotic resource enrichment as the bifurcation parameter}‎, ‎a Hopf bifurcation takes place‎, ‎where solutions with limit cycle behavior appear‎. ‎Varying further the parameter‎, ‎a fold bifurcation of the limit cycle takes place‎, ‎where the unstable limit appeared due to Hopf bifurcation reverses its growing direction and changes its stability‎. ‎Taking the predation rate as the {bifurcation parameter}‎, ‎saddle-node bifurcations take place‎. ‎The existence of stable interior equilibria and stable periodic solutions‎, ‎of which all prey and predator populations and the resource co-exist‎, ‎guarantee the boundedness of the size of the populations and the resource‎. ‎This is good from the conservation of an ecosystem point of view‎.
