The terrestrial vertebrates of the Bazaruto Archipelago, Mozambique: a biogeographical perspective

Data on the birds, amphibians, reptiles and mammalian species of the Bazaruto Archipelago, Mozambique are presented. Species diversity was compared to island size and with data for other East African Islands. There was a low degree of endemism and the different faunas (particularly for mammals and the herpetofauna) were mainland in origin and a nested subset of that on the mainland. Several mammal and bird families were absent from the islands suggesting a process of relaxation on these relatively young islands with little colonization. Reasons for the observed diversity are discussed.
