Abstract: | Summary In this paper I reviewed mammalian biogeography for 19 archipelagoes and tested the applicability of the equilibrium theory of island biogeography to mammalian faunas in general. The species-area and species-isolation relationships of terrestrial mammals were consistent with the basic predictions of the equilibrium theory. The z-values for the species-area relationship did not differ significantly from Preston's canonical value of 0.26 (P>0.50), and the modal z-value for non-volant mammals was 0.25. Moreover, z-values increased with isolation and decreased with vagility of the fauna in question. Furthermore, the strength of the species-isolation correlation was negatively correlated with island area and vagility (P<0.001). |
