Abstract: This paper describes the dynamical behavior of two different systems consisting of two preys and a predator. It also deals with the stability of tri-species community in the systems by means of both qualitative and quantitative approaches. The existence and local stability of the equilibrium points of the systems were analyzed. Harvesting activity in both prey and predator populations plays a significant role in controlling the spread of disease.
Keywords: Prey-Predator system, Qualitative stability, Iteration matrix, Quantitative stability, Harvesting Activity.
