OverviewThe aim of this module is to explore the evolutionary, ecological and biological concepts underlying biodiversity. Patterns of species richness, endemism and extinction risk will be examined at different spatial scales using recently available global datasets for mammals, birds and amphibians. We will consider the abiotic and biotic processes that explain these patterns including: - climatic, latitudinal and altitudinal gradients; topography; productivity; habitat heterogeneity and human population density. The main anthropogenic threats to biodiversity will also be examined including climate change, habitat loss, fragmentation, over-exploitation and invasive species. Finally, predictive models of future biodiversity loss will be appraised.
