Review

‘Dynamic Biogeography’ is an attempt to give biogeography its own place between other biological disciplines. Hengeveld defines dynamic biogeography as an analysis and understanding of spatial biological phenomena in terms of past and present factors and processes. Species ranges are dynamic structures varying with changing environmental conditions. The book is arranged from broad scale to fine scale patterns and processes, from classifications to detailed models of species ranges. Although this book is written from an ecological point of view, the author stresses the idea that biogeography should not be restricted to e.g. ecological or historical processes. For the herbarium systematist it will be often impossible to work with the large data collections necessary for statistical descriptions, however.
