Evolutionary impacts of climate change in Australia's fossil record
Grant number: DE180100629 | Funding period: 2018 - 2020
This project aims to identify evolutionary responses to climate change in Australia's fossil record by comparing variation in lizard and frog communities across geological time. Using X-ray techniques on museum specimens, this project will generate a large-scale database for tracking evolutionary shifts in relation to historical climatic events. Expected outcomes include the first anatomical descriptions for many species, filling major gaps in our ability to place fossils in a contemporary framework. This research will demonstrate the value of our national collections for addressing important environmental issues, such as biodiversity, extinction, and future habitat change.
