450 Million year history of plant gas exchange capacity and the role of atmospheric carbon dioxide. Our planet faces an increase in atmospheric carbon dioxide that is unprecedented in human history, but has occurred in ancient times. By studying the relationship between past changes in atmospheric carbon dioxide, plant gas exchange and climate we will gain powerful global insight into future scenarios of continental carbon and water fluxes. This global perspective is essential for Australia to a ....450 Million year history of plant gas exchange capacity and the role of atmospheric carbon dioxide. Our planet faces an increase in atmospheric carbon dioxide that is unprecedented in human history, but has occurred in ancient times. By studying the relationship between past changes in atmospheric carbon dioxide, plant gas exchange and climate we will gain powerful global insight into future scenarios of continental carbon and water fluxes. This global perspective is essential for Australia to assess its vulnerability to global climate change in relation to other nations, thereby informing national planning of landscape resource use, including primary industry, water infrastructure and carbon trading.Read moreRead less

The principle outcome of the research is the identification of sustainable land use management strategies that will ensure the continued productivity and profitability of food and fibre in the Australian sub-tropics and tropics in response to climate change whilst reducing greenhouse gas emissions. Regional communities will benefit through a greater awareness of emission sources and sinks and exposure to viable and practical strategies that promote productivity through regional diversity in land use. Improved data on greenhouse gas accounts will also ensure the Australia community is provided with full and accurate representation in international climate change fora and policy development.Read moreRead less
Modelling the impact of simulated warming on marine microbial production of dimethylsulphide on a global scale. The ultimate goal of Earth systems science is to understand the planet's functioning well enough to explain past changes (eg ice ages) and to predict future states of the system (eg the magnitude of greenhouse warming). This is possible only if the climate system can be accurately modelled. This project aims to examine the effect of simulated climate change on the global production of ....Modelling the impact of simulated warming on marine microbial production of dimethylsulphide on a global scale. The ultimate goal of Earth systems science is to understand the planet's functioning well enough to explain past changes (eg ice ages) and to predict future states of the system (eg the magnitude of greenhouse warming). This is possible only if the climate system can be accurately modelled. This project aims to examine the effect of simulated climate change on the global production of dimethylsulphide (DMS) by marine microbial ecosystems. DMS has been hypothesised as an important biogenic feedback on global warming.
This work will provide the first ecosystem modelling estimates of the
global radiative forcing due to DMS and thus decrease the uncertainty in current climate projections.Read moreRead less

The Cultural Impact of Irregular Marriage in the Age of British Colonialism, 1660-c.1860. Marriage has always been central to our understanding of relations between literature, society and culture. This project significantly revises that understanding by focussing on the irregular marriage practices which thrived in Britain and its colonies from 1660 to c.1860. It demonstrates, for instance, how the novel genre became respectable partly by marginalising irregular marriages; how Gretna Green we ....The Cultural Impact of Irregular Marriage in the Age of British Colonialism, 1660-c.1860. Marriage has always been central to our understanding of relations between literature, society and culture. This project significantly revises that understanding by focussing on the irregular marriage practices which thrived in Britain and its colonies from 1660 to c.1860. It demonstrates, for instance, how the novel genre became respectable partly by marginalising irregular marriages; how Gretna Green weddings came to typify modern romance in drama and fiction; and how marriage regulations underpinned literary portrayals of civil society in the Australian penal colony. It will deliver a groundbreaking monograph which accounts for marriage's role in modern literary culture in new terms.Read moreRead less
Drought, El Niño and Climate Change in Queensland over the last 200,000 years: the Lynch's Crater lake record. Lynch's Crater (Queensland) provides the longest, most sensitive terrestrial record of vegetation and climate change in the low altitude tropics. A multidisciplinary approach will exploit the potential of a core collected in 2003 through high-resolution multiproxy (sedimentology, geochemistry, stable and radiogenic isotopes, pollen, charcoal and diatoms) studies. The results will contri ....Drought, El Niño and Climate Change in Queensland over the last 200,000 years: the Lynch's Crater lake record. Lynch's Crater (Queensland) provides the longest, most sensitive terrestrial record of vegetation and climate change in the low altitude tropics. A multidisciplinary approach will exploit the potential of a core collected in 2003 through high-resolution multiproxy (sedimentology, geochemistry, stable and radiogenic isotopes, pollen, charcoal and diatoms) studies. The results will contribute substantially to the resolution of current debates on the role of the tropics in global climate forcing at a variety of temporal scales, including that of the El Niño phenomenon. The reconstruction of temperature and precipitation over the past 200,000 years will improve global climate databases and prediction models.Read moreRead less
Post-Quantum Functional Encryption : Principles, Protocols and Practice. Modern cryptography has the power to revolutionise virtually every aspect of our online lives. Large-scale secure data sharing could become a breeze, with tools such as functional encryption (FE) to give us fine control over access rights by means of expressive languages, and there will be no more juggling of crypto keys.

Modern cryptography has the power to revolutionise virtually every aspect of our online lives. Large-scale secure data sharing could become a breeze, with tools such as functional encryption (FE) to give us fine control over access rights by means of expressive languages, and there will be no more juggling of crypto keys. Finally, the known foundations of FE will crumble when even small-sized quantum computers become reality, perhaps next decade. This project aims to recreate and expand the power of FE from post-quantum (PQ) mathematical principles, immune to quantum attacks, building on recent discoveries of limited forms of PQ-FE from rock-solid crypto principles. It begs exploring, for the truly spectacular outcomes likely to ensue.Read moreRead less

It has become evident that biosphere processes need to be addressed at a global scale to understand global changes. Continental transects analyse ecosystem processes in a global context. The North Australian Tropical Transect (Darwin to Tennant Creek) represents 25% of Australia's vegetation. Biogeological research is underway on NATT ecosystems. Nitrogen availability strongly affects ecosystem productivity, and is of major interest as nitrogen pollution threatens the biosphere. In Australia, nitrogen levels are generally low, but overall knowledge is limited. An integrated ecophysiological approach will relate soil and plant nitrogen characteristics, and provide an analysis of nitrogen relations along NATT. Results will be linked to existing NATT and international transect research.Read moreRead less
