This study of biological invasions introduces dynamic concepts into biogeography and spatial concepts into ecology. By using mathematical models from epidemiology and human geography generalizations can be made and it is shown that apparently static species ranges contain dynamic internal parameters.

Cambridge Studies in Ecology presents balanced, comprehensive, up-to-date, and critical reviews of selected topics within ecology, both botanical and zoological. The Series is aimed at advanced final-year undergraduates, graduate students, researchers, and university teachers, as well as ecologists in industry and government research. It encompasses a wide range of approaches and spatial, temporal, and taxonomic scales in ecology, including quantitative, theoretical, population, community, ecosystem, historical, experimental, behavioural and evolutionary studies. The emphasis throughout is on...
