An Ecological Model of Mutualism Interaction between Two Species and a Predator

Y.Suresh Kumar, N. Seshagiri Rao, K. Kalyani


In the present article, we discuss the dynamics of logistically growing three species ecosystem. The system is involving mutualism interaction between two species and the third species, a predator which is surviving on both mutual species. We identified the possible equilibrium points of the system and discussed the local stability analysis around extinct and partially washed out states, and also presented the trajectories of the species. Finally computer simulations have been carried out to illustrate different analytical findings.
