Dynamic Complexity of a Three Species Competitive Food Chain Model with Inter and Intra Specic Competition

Abstract. The present article deals with the inter specic competition and intra-specic competition among predator populations of a prey-dependent three component food chain model consisting of two competitive predator sharing one prey species as their food. Stability analysis including local and global stability of the equilibria has been carried out in order to examine the dynamic behaviour of the system. As a result, intra-specic competition among predator populations can establish global coexistence. The ecological implications of both the analytical and numerical ndings are discussed at length towards the end.
