Dissecting biodiversity in a global hotspot: Uneven dynamics of immigration and diversification within the Cape Floristic Region of South Africa

Aim Fragmented distributions should show immigration and diversification dynamics consistent with the predictions of island biogeography theory. We test whether this applies to the fragmented Cape fynbos vegetation. Location Southern Africa, Cape Floristic Region (CFR). Taxon Angiosperms, Restionaceae (restios). Methods We used a large occurrence dataset and environmental layers to characterize an existing regionalization and the intervals...
