6-1.11 | CENOZOIC DIVERSIFICATION OF OCHNACEAE: CHARACTER EVOLUTION, BIOGEOGRAPHY AND CLIMATE CHANGE
The pantropical Ochnaceae belong to the large order Malpighiales and comprise about 500 species in 27 genera. The systematics, evolution and especially their historical biogeography are still poorly understood. We provide the first comprehensive molecular phylogeny of the family and reconstruct the evolution of key characters and the historical biogeography. Important questions refer to the factors triggering the radiations in the Neotropics and in Africa as well as to the role of dispersal mechanisms behind the pantropical distribution.
