摘要：
This paper studies influences of population dispersal on the dynamics of populations that live in patches and grow under Allee effect. Analytical conditions for the global stability of the model in the case of weak Allee effect are established by using the theory of monotonic dynamical systems. Numerical simulations are provided for the case of two patches and strong Allee effect, which reveal that a moderate migration to the better patch is beneficial to overall population, whereas a larger one is harmful. © 2016, Università degli Studi di Napoli "Federico II".
