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
Environmental change in northern Cenozoic Australia: a multidisciplinary approach. The Intergovernmental Panel on Climate Change (IPCC) warned that by 2020 to 2050, Australia will suffer significant biodiversity loss and water shortages. Our research will document and date the evolution of Australia's biota through three cycles of climate change over the last 25 million years to quantify and thereby better anticipate the nature and dimension of threats facing our natural and cultural communities ....Environmental change in northern Cenozoic Australia: a multidisciplinary approach. The Intergovernmental Panel on Climate Change (IPCC) warned that by 2020 to 2050, Australia will suffer significant biodiversity loss and water shortages. Our research will document and date the evolution of Australia's biota through three cycles of climate change over the last 25 million years to quantify and thereby better anticipate the nature and dimension of threats facing our natural and cultural communities. We will develop innovative techniques to date prehistoric biotic and climatic events and, using a range of tracers, characterize ancient environments and groundwater. This project will assist rural and regional Australia through education and job creation in geotourism and natural resource interpretation and provide a mechanism to combat generational skill shortage.Read moreRead less
The evolution of Australian rainforest faunas and the implications of continuing climate change. Australia's rainforest animals and ecosystems have been evolving for millions of years yet we routinely use only the last 200 years to assess changes that will affect their future - far too short a time interval to distinguish short-term perturbations from long-term trends in lineage health or community response. Our multidisciplinary team proposes to learn from 55 million years of response to rainfa ....The evolution of Australian rainforest faunas and the implications of continuing climate change. Australia's rainforest animals and ecosystems have been evolving for millions of years yet we routinely use only the last 200 years to assess changes that will affect their future - far too short a time interval to distinguish short-term perturbations from long-term trends in lineage health or community response. Our multidisciplinary team proposes to learn from 55 million years of response to rainfall and other climate change documented by the spectacular national, natural treasures in the fossil deposits of Tingamarra, Riversleigh and Rockhampton, to assess probable impacts of future environmental change and inform development of effective, long-term conservation strategies for rainforest communities.

The mighty ape’s last stand. This project aims to study the fate of primates in southern Asia, where evidence for megafaunal extinction is rare. Why Gigantopithecus blacki, the largest ever primate, disappeared is unknown, while humans in the region survived. This project will model dating techniques across sites to identify a precise extinction window and compare behaviour and past environmental conditions to determine why the ape failed and man persevered. Outcomes will generate a new understa ....The mighty ape’s last stand. This project aims to study the fate of primates in southern Asia, where evidence for megafaunal extinction is rare. Why Gigantopithecus blacki, the largest ever primate, disappeared is unknown, while humans in the region survived. This project will model dating techniques across sites to identify a precise extinction window and compare behaviour and past environmental conditions to determine why the ape failed and man persevered. Outcomes will generate a new understanding of past environmental change as a driver of megafaunal extinction in comparison with human adaption and survival.Read moreRead less
