Brief summary: 
This project will reconstruct the role that environmental change had in shaping genetic and biodiversity in Africa.
Importance of the area of research concerned: 
The response of biodiversity to global change is one of the most concerning issues facing our society. Yet, our ability to predict adaptation and biological change in the face of environmental change is limited at best. Past climatic changes provide the ideal testing ground for ideas and tools. However, reconstructing the past is full of challenges due to the scarce data available.
Project summary : 
This project will reconstruct the role that environmental change had in shaping genetic and biodiversity in Africa. By leveraging a new set of climatic reconstructions for the last 800k years, together with published as well as novel genetic data on birds and mammals provided by collaborators, we will reconstruct the extent of different biomes through time, and how changes in climate led population divergence and, eventually, speciation. By considering two lines of evidence simultaneously, we will compensate for the limited paleoclimatic proxies available for this continent, and aim to achieve a climatic history that is consistent with the evolutionary signals from the African fauna.
What will the student do?: 
The student will work with a novel spatial modelling framework that allows us to investigate the role of climatic change on demography and genetics. By exploring the coherence between climatic reconstructions and genetic data, the student will be able to investigate whether different lines of evidence provide a coherent story. The student will be able to explore the uncertainties on both climatic and genetic reconstructions. The work is fully computational, handling large data and working with Next Generation Sequence.
