The profound consequences of the deceptively obvious statement that plants stand still but their genes don't are only just becoming clear. In this volume, an international team of authors, experts in the field of population biology, aim to advance our understanding of ecological and evolutionary processes by integrating them within a common frame of reference; space. Processes operating at three different spatial scales are examined; that of the population, the metapopulation and geographical range. Themes that recur at these different scales include spatial population dynamics, population genetics at boundaries, the imprint of spatial population dynamics upon genetic structure, adaptation, evolution of mating systems and the consequences of population genetics for ecological dynamics. Whilst the focus is largely on plants, all of the questions addressed in this volume are equally applicable to animals and several authors write about both. It will be a valuable tool for researchers and advanced students, not only in this field, but also evolutionary biology and resource management.
