AbstractWe study a model for a structured population with a two-phase life cycle. Growth and reproduction occur during the first phase. The first phase is followed by a dispersal phase in which individuals are allowed to move throughout a habitat. We study the extinction and survival of the population from the bifurcation point of view. We prove the existence of positive equilibria and analyze their asymptotic stability near the extinction equilibria, relating it to the direction of bifurcation. Finally we investigate the spectrum of the branch of positive solutions.
