M.A.S. Srinivas*, Y. Narasimhulu, M. N. Srinivas

Abstract


In this article, a mathematical formulation is proposed and analyzed to study the dynamics of a prey predator model with stage structure of predators (adult and juvenile) in the habitat consisting of two patches. In this paper by harvesting the prey species in both the patches, steadiness of the system is discussed. The existence of its steady states and their stability (local and global) are analyzed.Biological and Bionomical equilibriums of the system are derived. Numerical simulation has also been performed in support of analysis by using Matlab.


Keywords


Prey predator, local and global stability, harvesting, bionomic equilibrium.
