| Summary: | Over the last 30 million years, Australia’s landscape has undergone dramatic cooling and drying due to the establishment of the Antarctic Circumpolar Current and change in global CO2 levels. Studies have shown that many Australian organisms went extinct during these major cooling events, while others experienced adaptive radiations and increases in diversification rates as a result of exploiting new niches in the arid zone. Despite the many studies on diversification and biogeography in Australia, few have been continent-wide and none have focused on a group of organisms adapted to feeding on plants. We studied 162 species of cicadas in the Australian Pauropsalta complex, a large generic lineage within the tribe Cicadettini. We asked whether there were changes in the diversification rate of Pauropsalta over time and if so: 1) which clades were associated with the rate change? 2) did timing of rate shifts correspond to known periods of dramatic historical climate change, 3) did increases in diversification ... : Owen_et_al_mtDNA_nDNANexus file that includes mtDNA and nDNA alignment with a partition block at the bottom of the file.Owen_et_al_nDNAonlyNexus file that contains only the nDNA alignment.
