Summary
Luminescence stimulation and detection facility for dating of Quaternary geological and archaeological sediments. Reliable ages are required in the Earth and archaeological sciences. Luminescence dating is a flexible geochronological technique for diverse deposits. It exploits the radiation-induced thermally (TL) and optically stimulated luminescence (OSL) emissions from minerals exposed to sunlight before burial. Recent technical developments have made feasible OSL dating of small samples (e.g. ....Luminescence stimulation and detection facility for dating of Quaternary geological and archaeological sediments. Reliable ages are required in the Earth and archaeological sciences. Luminescence dating is a flexible geochronological technique for diverse deposits. It exploits the radiation-induced thermally (TL) and optically stimulated luminescence (OSL) emissions from minerals exposed to sunlight before burial. Recent technical developments have made feasible OSL dating of small samples (e.g., individual sand grains) and sediments deposited during the past 0.5-1 million years. We request funds for a Risø TL/OSL system with single-grain attachment to resolve the timing of sea-level, climate and landscape changes, and the chronology of human evolution and dispersal, in Australia and Southeast Asia.Read moreRead less
Radiocarbon dating frontiers: Testing hypotheses of human evolution and environmental change in Australasia and Southeast Asia (60,000-25,000 years ago). Radiocarbon (14C) dating has revolutionised our understanding of archaeological events and past environments. However, much of the period 60,000-25,0000 years ago is beyond the traditional limit of the method (40,000 years). This is unfortunate as this period is characterised by rapid, extreme shifts in climate during which the global spread ....Radiocarbon dating frontiers: Testing hypotheses of human evolution and environmental change in Australasia and Southeast Asia (60,000-25,000 years ago). Radiocarbon (14C) dating has revolutionised our understanding of archaeological events and past environments. However, much of the period 60,000-25,0000 years ago is beyond the traditional limit of the method (40,000 years). This is unfortunate as this period is characterised by rapid, extreme shifts in climate during which the global spread of modern humans took place. This project will utilise the latest developments in 14C dating (allowing ages up to 60,000 years ago) to test hypotheses concerning the timing of human arrival and settlement in Southeast Asia and Australasia, their environmental impact, and the synchroneity of climate change between the hemispheres.Read moreRead less

Accurate timekeeping is central to the environmental and archaeological sciences. Radiocarbon dating is the leading geochronological technique for events of the past 50,000 years, but the issue for sample contamination remains a major source of concern. Avoidance of contaminants can be achieved through the identification of specific biomolecular compounds that unambiguously formed part of the original sample, and the isolation of these biomolecules for radiocarbon dating using accelerator mass spectrometry. Here we request funds to establish Australia's first compound-specific radiocarbon dating facility, to obtain ages of high accuracy for key studies of climate and landscape change, evolutionary biology and archaeology.Read moreRead less
Unravelling the last great Gondwanan mystery: the first land vertebrate fauna from the Tertiary of New Zealand. This project will dramatically increase knowledge about Australia's and New Zealand's shared biodiversity and the history of trans-Tasman dispersals. By comparing Australian and New Zealand fossil records, it will be possible to assess the speed at which evolving vertebrates of one landmass invade another, as well as the biotic consequences of such events, and provide data important fo ....Unravelling the last great Gondwanan mystery: the first land vertebrate fauna from the Tertiary of New Zealand. This project will dramatically increase knowledge about Australia's and New Zealand's shared biodiversity and the history of trans-Tasman dispersals. By comparing Australian and New Zealand fossil records, it will be possible to assess the speed at which evolving vertebrates of one landmass invade another, as well as the biotic consequences of such events, and provide data important for predicting and responding to future potentially-damaging events of this kind. Developing understanding about the timing and intensity of antipodean faunal response to past climate change will improve ability to anticipate and manage processes that threaten ecosystem resilience in both lands.Read moreRead less

This study will yield important new data on the time of entry of humans into a previously uninhabited continent (North America) and the record of subsequent human-environment interactions. The same broad issues apply to Australia, so understanding the sequence and causes of events in Beringia will provide insights into human disruption of the Australian ecosystem. The development of improved techniques in palaeogenetics and geochronology will benefit researchers worldwide, increase the capacity for commercial services, and enhance Australia's international standing in cutting edge science. We will train high-quality graduate students and create new collaborative initiatives and opportunities for research, exchange, training and education.Read moreRead less

Modern Approaches To A Prehistoric Puzzle. Animal species will be, and have been, threatened with extinction continuously through time. Understanding the possible role of people in these events and how climate change may have made some species more vulnerable to extinction than others is an important aspect of ongoing debate in our society. How these factors influenced the extinction process has implications for how we might manage our policies on land, conservation, biodiversity, and 'at-risk' animal species. Additionally, the involvement of indigenous communities provides important employment and cultural exchange opportunities.Read moreRead less

Biodiversity research is strong in Australia but is highly uncoordinated and, along with recent major breakthroughs in both theory and techniques, has highlighted the need for a Network to properly integrate research and focus it on the most appropriate scale. This Network aims to bring together a diverse spectrum of highly experienced and early career researchers to pool their ideas and expertise to allow them to determine how best to describe Australia's current biodiversity and the biological and environmental history leading up to the present. A major outcome will be the ability to predict the impacts of environmental change on biodiversity to assist management decisions across Australia, with lessons of global importance.Read moreRead less
An innovative approach to maximising catchment water yield in a changing climate. Australia is facing a crisis in water availability and management within many of the continent's major cities and the Murray-Darling and Sydney Basins. Risk to water resources will also be exacerbated by climate change.

Australia is facing a crisis in water availability and management within many of the continent's major cities and the Murray-Darling and Sydney Basins. Risk to water resources will also be exacerbated by climate change. Past solutions of increasing water supply by building dams are no longer easily implemented because of the significant environmental consequences. To maximise yield, better management of current resources is required, dependent on understanding what factors affect water yield and how they may be better manipulated. This project innovatively integrates ecological and hydrological processes by modelling the expression of water use by vegetation and its management and water availability at fine resolutions.Read moreRead less
