Biogeography: An ecological and evolutionary approach

The science of biogeography asks, and seeks to answer, many varied questions. Why are there so many different kinds of animals and plants? Why are some common and some rare? Why are some widely dispersed and others confined to very limited areas? Why are some habitats and parts of the world so much richer in species than others? How have these patterns of distribution and species richness evolved?. "The book is intended as the principal text for students taking courses in biogeography, as well as wider degree programmes in which the study of biogeography is important, such as geography, ecology, palaeobiology and evolution.
