Persistence and global stability for a class of discrete time structured population models

Abstract

We obtain sharp conditions distinguishing extinction from persis- tence and provide suffcient conditions for global stability of a positive fixed point for a class of discrete time dynamical systems on the positive cone of an ordered Banach space generated by a map which is, roughly speaking, a nonlinear, rank one perturbation of a linear contraction. Such maps were con- sidered by Rebarber, Tenhumberg, and Towney (Theor. Pop. Biol. 81, 2012) as abstractions of a restricted class of density dependent integral population projection models modeling plant population dynamics. Significant improve- ments of their results are provided.
