| Abstract: | This paper considers a class of three-dimensional ecosystem in which the lowest trophic level prey exhibits group defence with respect,to thefirst predator or both predators.Some sufficient conditions for persistenceof all population are given in terms of studying stability of all boundaryequilibria and periodic,orbits.The results derived supply theoreticalfoundation and effective method to ecologica balance as this ecosystem. |
