    Abstract

    A conserved version of the fisher equation with reference to population dynamics with global regulation was analyzed. A model was developed to describe the spatially extended populations with fixed number of indivisuals. A rich spectrum of dynamical phases including pseudotraveling wave was observed. The results show that there was a phase transition from a locally constrained high density state to a low density fragmented state in the presence of the Allee effect.
