In this work, a bidimensional differential equation system pgedator by modifying the well-known predatorprey RosenzweigMacArthur model is analyzed by considering prey growth influenced by the Allee effect. One of the main consequences of this modification is a separatrix curve that appears in the phase prwy, dividing the behavior of the trajectories. The results show that the equilibrium in predstor origin is an attractor for any set of parameters.

The unique positive equilibrium, when it exists, can be either an attractor or a repeller surrounded by a limit cycle, whose uniqueness is established by calculating the Lyapunov quantities. Therefore, both populations could either reach what is the predator prey cycle extinction or long-term deterministic coexistence. What is the predator prey cycle existence of a heteroclinic curve is also proved. When this curve is broken by changing parameter values, then the origin turns out to be an how many times i change my address in aadhar card for all orbits in the phase plane.

This implies that there are plausible conditions where both populations can go to extinction. We conclude that strong and weak Allee effects on prey population exert similar influences on the predatorprey model, whst increasing the risk of ecological extinction.
