PhD research project

Biogeography of Atlantic Central Africa - Tridactyle (Orchidaceae): a story of speciation and colonisation at São Tomé and Príncipe


Supervisors: Patrick Mardulyn and Tariq Stévart


This project addresses the evolutionary and biogeographic processes underlying biodiversity patterns in tropical African plants. The experimental model, epiphytic orchids, is a prominent component of tropical rainforests, especially in São Tomé and Príncipe, two oceanic islands recognized as biodiversity hotspots. The genus Tridactyle (Orchidaceae) will be used as a model to test speciation and diversification scenarios in the context of the theory of island biogeography. A taxonomic revision will be first conducted, based upon a molecular phylogeny, also including materials from continental Africa. The possible scenarios will be then examined at the intraspecific and interspecific level. The demographic history of the group will be studied, with a focus on Tridactyle tridactylites. We will test whether the speciation history of Tridactyle species is similar to other closely related Angraecoid orchids and to other families from rainforests.
