This book, written as an introductory manual on biography caters perfectly to needs of students of geography or the biological sciences. Serving as an essential key for understanding biodiversity, biogeography is one the most relevant, as well as increasingly studied scientific disciplines today.

The book, training the history, origin and developments of the field, delineates the processes, principles and practices in the applications of this science, especially with regard to analysing patterns of species distribution. These patterns, which can be explained through a combination of factors such as speciation, extinction, continental drift, glaciation and river capture, have been given considerable attention, for form a major part of the book's content.
