Researchers are using a new model to clarify why millions of years ago more animal species from Asia made the leap to the Australian continent than vice versa. The climate in which the species evolved played an important role.
The 2015–2018 summer droughts have been exceptional in large parts of Western and Central Europe over the last 400 years, in terms of the magnitude of drought conditions. This indicates an influence of man-made global warming.
Lake Mungo is home to some of the earliest and most significant archaeological sites in Australia and contains a sedimentary archive that charts environmental change throughout the Willandra Lakes Region. This thesis sets out to provide a methodological approach to integrate the archaeological and environmental record of Lake Mungo. This study had 3 aims: to assess the stratigraphic integrity of these hearth features using soil micromorphology and Fourier transform infrared (FTIR) spectroscopy; to integrate these archaeological traces into the wider landscape by analysing the stratigraphic rec...
To understand more about the secretive lives of reef fish, researchers have used environmental DNA present in seawater to determine whether a species occurs at the location in question.
The Finke River in central Australia is counted among the world's oldest drainage systems; this raises the prospect of investigating how (tectonic and sub-lithospheric) processes have shaped the landscape in the long term. The Finke's upper reaches display an enigmatic set of intertwined active and relict bedrock gorges that suggest a complex history of incision, aggradation and re-incision. We measured cosmogenic 10Be and 26Al in fluvial gravels preserved in the gorges, and we applied a Markov chain-Monte Carlo-based inversion model to test two limiting-case hypotheses about the tim...
