How do time, climate change and adaptation shape the assembly and evolution of a diverse continental biota?

This project will use new statistical techniques for analysing patterns of biological diversification to test how time, environmental change and evolutionary adaptation shape the accumulation of biodiversity in a continental setting. A supermatrix of genetic and ecological data for Australia's most diverse terrestrial vertebrate group (lizards and snakes) will be compiled. This will allow the testing of the macroevolutionary responses to key environmental changes through the Cainozoic (rapid climatic transgressions and aridification), the relationship between lineage age and species diversity and the effects of major ecological shifts on rates of speciation, extinction and morphological diversification.
