Permanence and Extinction in a Class of PredatorPrey Model with three Life Stages
A class of predatorprey model with three life stages is investigated.The global attractivity of the nonnegative equilibriums is discussed by constructing Lyapunov functionals.Moreover
we obtain the conditions under which all the species keep permanent
the predator species become extinct or all the species become extinct
