Self-Regulation in an Ecology Model of Shared Predation

Vasyl Gafiychuk, Janos Turi

Abstract



Ecological system model of shared predation with two prey species is analyzed. We consider the case when the predator is active and pursuing maximum biomass flow. Such behavior leads to self-regulation in the food web community and prevents the extinction of species from the ecology system. The results of computer simulations on the proposed model are presented for certain choices of coefficients corresponding to predator prey interactions. It is shown that the system with active strategy of the predator is much more stable than the system described by a classical Lotka-Volterra model. This result qualitatively does not depend on the specific chase strategy of the predator.
