Introductionion seems to require that we do not use all the apparently relevant data. Latitudinal diversity gradients (Chapter 3) and species-area relationships (Chapter 4) are examples. How do we decide which data are useful? Any satisfactory exlplanation of the patterns must encompass both supporting and conf

Cladistic biogeographyd South America. However, when examined from a taxonomic point of view the species in the different areas are quite distinct from one another. In other words, species in similar ‘niches’ are different taxa which have had different histories. Historical biogeography focuses on evolution - change in t

Speciations of speciation: inferences in biogeography may therefore depend on how new species arise. Finally, the wealth of molecular data now becoming available gives accurate information about phylogenies over the very long time-scales with which much of biogeography is concerned.

Phylogenetic biogeographyd and several islands in the southern temperate and subantarctic zones. The results were published in the . (1844–47), . (1853–55) and . . Although mainly taxonomic, these works contain introductory essays which are of great biogeographic interest.

mplexity of the subject. Biogeography transcends classical subject areas and involves a range of scientific disciplines that includes geogra phy, geology and biology. Not surprisingly, therefore, it means rather different things to different people. Historically, the study of biogeogra phy has bee
