Description: This work aims to understand the biogeographic and biodiversity dynamics driven by Plio-Pleistocene dry/humid climatic cycles in the Sahara-Sahel desert. The main objectives are to test: i) climate-induced allopatric speciation as the main diversification agent; ii) biodiversity refugia and dispersal corridors; iii) relationships between genetic diversity and environmental-dependent taxa persistence in refugia. I examine whether genetic/spatial isolation is strong in low dispersal ability taxa, and whether taxa-specific habitat requirements are related to distinct spatial/temporal locations of refugia and of dispersal corridor dynamics. I integrate distribution, climate, and genetic data from greater than 30 co-distributed taxa with different dispersal abilities and habitat traits. I compare predicted refugia by genetic variability and species distribution modelling, while controlling for taxa-specific dispersal and habitat traits.
