International Trade Policy and the Dynamics of Open Economies. The project is concerned with the relationship between an open economy's international trading conditions and the allocation of resources within the economy, particularly over time (dynamic effects). The trading conditions reflect international markets and governments' trade policies. The dynamic effects upon the economy include the rate of growth, saving and inter-generation welfare. The models developed to study these relationship ....International Trade Policy and the Dynamics of Open Economies. The project is concerned with the relationship between an open economy's international trading conditions and the allocation of resources within the economy, particularly over time (dynamic effects). The trading conditions reflect international markets and governments' trade policies. The dynamic effects upon the economy include the rate of growth, saving and inter-generation welfare. The models developed to study these relationships will link international markets with domestic and future markets in a unified and consistent manner. The outcomes include a better theoretical understanding of these relationships and empirical inter-temporal models for the Australian economy that permit measurement of these dynamic effects.Read moreRead less
Early African woodworking and tool use at the transition to modern humans. Our archaeological excavations and preliminary dating of Amanzi Springs (South Africa) to between 515,000 and 163,000 years ago shows that the site covers a critical time period that led to the origins of our species, Homo sapiens. Amanzi documents, in never before seen resolution, the technological leaps that our ancestors made during this transition. At ~400,000 years ago this includes the oldest evidence for woodworkin ....Early African woodworking and tool use at the transition to modern humans. Our archaeological excavations and preliminary dating of Amanzi Springs (South Africa) to between 515,000 and 163,000 years ago shows that the site covers a critical time period that led to the origins of our species, Homo sapiens. Amanzi documents, in never before seen resolution, the technological leaps that our ancestors made during this transition. At ~400,000 years ago this includes the oldest evidence for woodworking and tool use and >163,000 years ago the oldest heat treatment of rock to make stone tools. The organic preservation at the site means that we can reconstruct changing environment, linked to sea level changes and spring activity, for this period in the evolution of our ancestors at a level of detail not previously possibleRead moreRead less

Understanding the survival of forests under drought . Droughts are predicted to become more extreme in the near future, with potentially devastating impacts on Australian forest ecosystems. This project aims to address key knowledge gaps in our understanding of how plants tolerate extreme drought stress and utilise this new knowledge to improve vegetation models suitable for assessing ecosystem vulnerability. We will use innovative experimental methodology to determine the processes by which wat ....Understanding the survival of forests under drought . Droughts are predicted to become more extreme in the near future, with potentially devastating impacts on Australian forest ecosystems. This project aims to address key knowledge gaps in our understanding of how plants tolerate extreme drought stress and utilise this new knowledge to improve vegetation models suitable for assessing ecosystem vulnerability. We will use innovative experimental methodology to determine the processes by which water transport breaks down in roots, stems and leaves and the mechanisms governing recovery from severe drought stress. The project will provide a deeper understanding of drought tolerance in trees, improved forecasting of risks to native vegetation, and enhanced management of native forest resources.

The Social Production of Science in Antarctica: A Study of Davis Station. Antarctica is a unique scientific laboratory. It is the only continent historically uninhabited by humans; access to its vast land and ice-scapes, and its surrounding oceans, is today almost exclusively reserved for scientists. Although these 'Antarcticans' represent multiple disciplines, and pursue a wide variety of research agendas, their shared experiences of working on the continent, and their shared professional netwo ....The Social Production of Science in Antarctica: A Study of Davis Station. Antarctica is a unique scientific laboratory. It is the only continent historically uninhabited by humans; access to its vast land and ice-scapes, and its surrounding oceans, is today almost exclusively reserved for scientists. Although these 'Antarcticans' represent multiple disciplines, and pursue a wide variety of research agendas, their shared experiences of working on the continent, and their shared professional networks, mean that they constitute a distinct community of practice. However, this community has yet to be subjected to detailed ethnographic enquiry. This project aims to examine Antarctic scientists' research practices, and their cultures of knowledge production, through an ethnographic study of Australia's Davis Station.Read moreRead less
Understanding leaf water isotope composition. This project aims to quantify variation in leaf water isotopes and develop mechanistic models for paleoclimatologists and plant scientists to constrain global carbon cycles. Leaf water stable isotopes influence the isotope compositions of atmospheric oxygen, carbon dioxide and water vapour, and impart an evaporative signal on the isotope composition of plant organic material. These isotope signals have been used to constrain global carbon and water c ....Understanding leaf water isotope composition. This project aims to quantify variation in leaf water isotopes and develop mechanistic models for paleoclimatologists and plant scientists to constrain global carbon cycles. Leaf water stable isotopes influence the isotope compositions of atmospheric oxygen, carbon dioxide and water vapour, and impart an evaporative signal on the isotope composition of plant organic material. These isotope signals have been used to constrain global carbon and water cycles and reconstruct past climates. This project aims to quantify variation in leaf water isotopes and develop mechanistic models for use by paleoclimatologists, plant scientists and to constrain global carbon cycles and develop accurate models of leaf water isotopes to reduce uncertainty in climate models.Read moreRead less

This project aims to examine how resilient Eucalyptus species are to future droughts by combining data synthesis, manipulative experiments and modelling. Climate change is expected to increase the frequency, magnitude and duration of future droughts, with major environmental and socio-economic consequences for Australia. Current predictive capacity is extremely limited: experiments are limited in scale and cannot capture important global change interactions, whilst models do not represent the functional characteristics and adaptions of eucalypts. This project will develop a strong evidence- and process-based understanding to quantify the functional behaviour of drought-adapted Eucalyptus species and leverage this insight to make future model projections.Read moreRead less
