Local interactions and invasion dynamics: Population growth in space and time

Abstract

The study of biological invasions is essentially the study of population growth in both space and time. Not only are we interested in the population size of an invader, but also its rate of spread across a landscape or region. Hence theoretical models of invasions very often incorporate some form of spatial heterogeneity (Skellam 1951, Boerlijst and Hogeweg 1991, Hassell et al. 1994, Kot et al. 1996, Keeling et al. 199 7, Lewis 2000, Lewis and Pacala 2000, Rietkerk et al. 2002). © 2006 Springer.
