La región florística del Cabo en Sudáfrica es definitivamente el hotspot de biodiversidad mas importante del mundo;
This Week in SCIENCE, Volume 309, Issue 5741, dated September 9 2005, is now available at: The fynbos Mediterranean shrubland of the Cape Floristic Region of South Africa is one of the most species-rich plant habitats on Earth. Latimer et al. (p. 1722) find that the region's high plant diversity is associated with low migration rates and with speciation rates higher than those in themost diverse tropical forests such as Amazon rain forest. The local species abundance patterns in fynbos is a mosaic made up of centers of locally endemic plants, with little migration among them and relatively few universally rare species, unlike the well-mixed tree communities of Amazon upland rain forest.
