Impact of Harvesting in Three Species Food Web Model With Two Distinct Functional Responses

Madhusudanan. V, Vijaya. S, Gunasekaran. M

The intuition with two-species models may be applied to community food web questions. The critical behavior to community function may arise only through the interaction of three or more species. In this paper we investigate the dynamical behavior of the system consisting of two preys with distinct functional responses and a predator. We also study the effect of harvesting on prey species. Harvesting is strong impact on the dynamics evaluation of population. To a certain extent it can control the long term stationary density of population efficiently. Finally the local and global stability analyses were carried out.
