How have interactions between climatic change, human activities and other disturbances over thousands of years shaped the landscapes we know today in Australia? Existing lines of evidence from palaeoecological and archaeological sources point to significant changes to biodiversity, vegetation cover, and fire frequency since the arrival of people into Australia sometime between 50000 to 40000 yr BP. The extent to which humans influenced or overrode natural processes through time remains unclear. High-resolution, multi-proxy data in an innovative vegetation and megafaunal reconstruction will provide the first quantitative assessment of the response of Australian tropical savannas to a range of natural and anthropogenic influences.

数千年来，气候变化、人类活动和其他干扰之间的相互作用如何塑造了我们今天所知的澳大利亚景观？现有的证据线从古生态和考古来源指向生物多样性，植被覆盖和火灾频率的显着变化，因为到达澳大利亚的人之间的某个时候50000至40000年BP。人类在多大程度上影响或超越了自然过程，目前还不清楚。在一个创新的植被和巨型动物重建的高分辨率，多代理数据将提供澳大利亚热带稀树草原的一系列自然和人为影响的反应的第一个定量评估。
