Biogeography has long remained in a natural history phase, but the authors of this book believe it is in a position to enter an experimental and theoretical phase―that it can now be discussed in terms of the first principles of population ecology and genetics. Using mathematical and graphical models, they provide a first theoretical framework for faunal patterns on islands. Particular attention is paid to problems of island colonization, to the balance between immigration and extinction, and to the evolution of colonists following successful establishment. Wherever possible empirical evidence is assembled and compared with the theoretical predictions. Originally published in 1967.
