Driving forces of island biodiversity : an appraisal of two theories

Auteur :
WALTER, H.S.

Description :
The avifauna of three oceanic islands of the Revillagigedo archipelago in the eastern Pacific Ocean consists of 14 endemic landbird taxa and 3 recent continental colonists. This study analyzes the origin, aerography of continental relatives, ecological characteristics, and role of immigration and extinction factors as regulators of the islands'species. The endemic nature of the pristine avifauna is interpreted as an indication of high stability over thousands of years. The A. wishes to assess the validity and explanatory power of the MacArthur-Wilson and Lack theories with the Revillagigedo case study.
