Abstract

A model which describes the interaction of two prey species with two predators is analysed. Prey species are of large size and exhibit group defence. Both predators are of same species and they select prey species which are numerically less and have insufficient defending capability. We found conditions for nontrivial equilibrium to be asymptotically stable and corresponding numerical results are also presented.
