My dissertation is based on the systematics and evolution of the genus Carapa (Meliaceae). This is a poorly known genus of small to medium-sized trees of rain forest in western tropical Africa, central and northern South America, and the West Indies. The current literature recognizes 3 species in the new world and only one in Africa. Since the creation of the genus in 1775, thirty-three species names have been published, of which only three are considered valid today. However, there is a general consensus concerning the extreme variability of these 3 species. There is variation in individual trees habit, leaf length, leaflet shape and number, inflorescence branching, flower size, number of ovules per carpel, fruit size and the degree of development of resinous warts on their surface (see images). My general objective is to provide a new circumscription of species in Carapa using an evolutionary approach. My approach is to (1) describe and analyze the pattern of variation in Carapa using field observations and characters that had not been carefully observed and evaluated in the past, (2) provide information on the habitat and uses of the different species for their better conservation. Currently, I have initiated a species-level phylogeny using DNA sequencing of populations spanning the entire range of Carapa, in order to account for criptic genetic variation and in order to reconstruct the dispersal scenarios.
