Geographic Range Sizes and Trajectories to Extinction

Abstract

Study of the dynamics of extinction of single species has tended to treat temporal patterns of abundance and of spatial distribution rather separately. A framework is discussed for considering their interaction in this regard. This develops, with some possible examples, four simple idealized models describing the trajectory which might be taken to extinction, with respect to changes in the size of a species' geographic range and its total population size.
