الملخص الإنجليزي

This thesis treats the qualitative behavior of the dynamics for some ecological models.

Two types of prey-predator models are proposed and analyzed analytically as well as numerically in two different cases (wholly dependent predator and partially dependent predator).

In the first model, it is assumed that the habitat is divided into two disjoint zones, namely unreserved zone and reserved zone, while in the second model the stage structure factor of predator is added to the prey-predator model with a reserved area of Dubey [24].

The existence and uniqueness of the solution of these models are investigated.

The local and global dynamical behaviors are studied.

The conditions of persistence of the models are established.

The Hopf bifurcation analysis is carried out.

Finally, the effects of the existence of the reserved zone and stage structure on the dynamical behavior of both the models are discussed.
