Abstract :
[en] The fate of African tropical forests is a major concern for conservation, while their biodiversity is still poorly known. The purpose of this poster is to provide an update of knowledge of the genus Afzelia, a complex of sister tree species exploited for their wood in central Africa. The distribution of Afzelia in Africa suggests various adaptations to ecological factors. In fact, most of Afzelia species occur in parapatry and are so similar that they are often not distinguished by logging companies and forests managers. We show that the genus remains understudied in Africa although some of its species are considered as endangered or vulnerable. Therefore, a revision of its taxonomy along with thorough investigations of ecological and genetic aspects of Afzelia populations, using molecular markers currently in development (nSSR, cpDNA and nDNA), should be relevant and of great interest for conservation and sustainable management purposes. We will describe the different and complementary morpho-genetic approaches that will be used to investigate the biogeographical history of Afzeliapopulation in concert with species boundary questions.
