A Cretaceous origin for fire adaptations in the Cape flora
Fire has had a profound effect on the evolution of worldwide biotas. The Cape Floristic Region is one of the world's most species-rich regions, yet it is highly prone to recurrent fires and fire-adapted species contribute strongly to the overall flora. It is hypothesized that the current fire regimes in the Cape could be as old as 6-8 million years (My), while indirect evidence indicates that t...
متن کاملThe Cape element in the Afrotemperate flora: from Cape to Cairo?
The build-up of biodiversity is the result of immigration and in situ speciation. We investigate these two processes for four lineages (Disa, Irideae p.p., the Pentaschistis clade and Restionaceae) that are widespread in the Afrotemperate flora. These four lineages may be representative of the numerous clades which are species rich in the Cape and also occur in the highlands of tropical Africa....
متن کاملEstimating the age of fire in the Cape flora of South Africa from an orchid phylogeny.
Fire may have been a crucial component in the evolution of the Cape flora of South Africa, a region characterized by outstanding levels of species richness and endemism. However, there is, to date, no critical assessment of the age of the modern fire regime in this biome. Here, we exploit the presence of two obligate post-fire flowering clades in the orchid genus Disa, in conjunction with a rob...
متن کاملThe scaled chrysophyte flora of Cape Cod, Massachusetts, USA, with special emphasis on lake water chemistry
A total of 43 scaled chrysophyte taxa were observed in plankton collections made from 60 lakes and ponds on the peninsula known as Cape Cod, a peninsula extending into the Atlantic Ocean along the northeastern coast of the United States between 41 °30' and 42°00' North latitude. The waterbodies, primarily seepage lakes of glacial origin, are characterized as largely acidic, poorly buffered and ...
