This project aims to investigate the influence of bushfires and shifting rainfall patterns on the development of Australia’s dominant ecosystems. By combining a range of novel geochemical, isotopic and palaeontological techniques, this research seeks to reveal the causes and consequences of Australia’s transformation from a forested to mainly open landscape of grassland, shrubland and savannah. The expected outcome is detailed knowledge of how changes in fire and rain shaped the ecology and evolution of plants and animals. This knowledge is key to understanding how Australian ecosystems function and to protecting their cultural, economic and environmental values, especially as climate and fire regimes continue to change into the future.

该项目旨在调查森林大火和降雨模式变化对澳大利亚主要生态系统发展的影响。通过结合一系列新颖的地球化学，同位素和古生物学技术，这项研究旨在揭示澳大利亚从森林转变为草原，灌木丛和萨凡纳草原的主要开放景观的原因和后果。预期的成果是详细了解火和雨的变化如何塑造生态和植物和动物的进化。这些知识是了解澳大利亚生态系统如何运作和保护其文化，经济和环境价值的关键，特别是随着气候和火灾制度在未来继续变化。
