Temperature sensitivity of soil respiration and its components. This project aims to demonstrate how temperate evergreen forests could buffer against climate change. Soil respiration returns around half the carbon taken up by forests to the atmosphere. This project will characterise and quantify how microbes and roots in soils depend on temperature and substrate supply, and so predict how rising temperatures and drought will affect forests as natural carbon sequestration sinks. This project will ....Temperature sensitivity of soil respiration and its components. This project aims to demonstrate how temperate evergreen forests could buffer against climate change. Soil respiration returns around half the carbon taken up by forests to the atmosphere. This project will characterise and quantify how microbes and roots in soils depend on temperature and substrate supply, and so predict how rising temperatures and drought will affect forests as natural carbon sequestration sinks. This project will resolve the roles of environmental drivers of soil respiration across forests; integrate mechanistic understanding of differing plant and microbial responses to temperature within a common modelling framework; and evaluate the implications of this knowledge in predictions of climatic impacts on terrestrial carbon cycling.Read moreRead less
Trade-offs underlying the evolution of female mating strategies. Multiple mating by females (polyandry) is a fundamental problem in behavioural ecology. The project will utilise an Australian species of stingless bee to quantify both the costs and the most probable benefits of polyandry. This will provide insight into the trade-offs underlying the evolution of mating strategies in this species and in general. Stingless bees are important members of many Australian ecosystems and have consider ....Trade-offs underlying the evolution of female mating strategies.

The project will utilise an Australian species of stingless bee to quantify both the costs and the most probable benefits of polyandry. This will provide insight into the trade-offs underlying the evolution of mating strategies in this species and in general. Stingless bees are important members of many Australian ecosystems and have considerable economic potential as well. The knowledge gained during the project will also substantially aid the development and management of the commercial use of stingless bees, which will have both ecological and economic benefits to Australia.Read moreRead less
Turning water into carbon: a synthesis of plant water-use efficiency from leaf to globe. The efficiency with which plants use water to gain carbon is a fundamental aspect of plant growth that has been frequently measured but is poorly understood. Using our new theory to draw together major datasets, the project will make a dramatic advance in our ability to understand and predict this key aspect of ecosystem function.
Use of quinone adducted peptides in the regulation of fertility. This project describes a novel strategy for the non-surgical induction of sterility in male and female mammals with applications in the fields of biotechnology, veterinary medicine and the humane control of pest animal species. The approach is dependent upon the known sensitivity of the germ line to oxidative stress. The strategy rests upon the demonstration that quinone-adducted peptides will selectively bind to non-renewable cel ....Use of quinone adducted peptides in the regulation of fertility. This project describes a novel strategy for the non-surgical induction of sterility in male and female mammals with applications in the fields of biotechnology, veterinary medicine and the humane control of pest animal species. The approach is dependent upon the known sensitivity of the germ line to oxidative stress. The strategy rests upon the demonstration that quinone-adducted peptides will selectively bind to non-renewable cell types in the ovary and testis and redox cycle at the cell surface generating a highly localised state of oxidative stress. This stress will then recapitulate the impact of radiation on reproductive tissues by selectively compromising the viability of the germ line, inducing a state of sterility.Read moreRead less
Antifreeze Proteins and Glycoproteins. Antifreeze proteins and glycoproteins permit many species of fish to survive in sub-zero oceans without freezing. These antifreeze compounds have potential applications in the frozen food industry (eg. maintaining the texture of ice cream), medical science (eg., cryosurgery) and veterinary science (eg. storage of sperm). Commercial applications are limited by the amounts of compounds available from fish and the lack of understanding of how these proteins ....Antifreeze Proteins and Glycoproteins. Antifreeze proteins and glycoproteins permit many species of fish to survive in sub-zero oceans without freezing. These antifreeze compounds have potential applications in the frozen food industry (eg. maintaining the texture of ice cream), medical science (eg., cryosurgery) and veterinary science (eg. storage of sperm). Commercial applications are limited by the amounts of compounds available from fish and the lack of understanding of how these proteins work. This research will study how natural and synthetic antifreezes inhibit ice growth in order to allow the rational design of new antifreezes and will identify new compounds with potential commercial applications as cryoprotectants.Read moreRead less

The results of this project will directly contribute to a better understanding of crystallisation which is an important unit operation to achieve high purity separations. Many Australian industries for example, mineral processing, sugar processing, pharmaceuticals, etc will benefit from the results in order to enhance optimal operation and control to ensure globally competitive production which is on time, minimize wastes and raw materials and inventories. The leading edge results will increase the contributions of these industries to the Australian economy and our global competitiveness necessary to maintain our culture and the beauty of our environment.

Renewable solar hydrogen generated from waste streams. Sunlight is the largest available carbon-neutral energy source, with enough energy striking the planet in one hour to satisfy our current requirements for about a year. With the novel catalysts designed in this project, we will use this energy to simultaneously generate hydrogen and destroy organic pollutants by oxidation.
The hunt for Ribonucleic Acid riboswitches and genetic sensors of metabolic flux in plants. Ribonucleic Acid (RNA) contains both structural and sequence information that coordinates feedback of metabolic processes in response to environmental change, thereby promoting cellular adaptation and survival. This project will discover ancient RNA modules and structural switches in plants that sense chemical reactions and regulate pathway flux.
The basics of reading: How are letter-strings identified as words? In order for people to read effectively, the mental representation of each letter-string must be found in long-term memory. The aim of this project is to more fully understand the nature of proficient visual word recognition with a particular focus on the way in which the form of the word is mentally stored and retrieved during the act of reading. A range of issues will be examined from letter position coding through to how words ....The basics of reading: How are letter-strings identified as words? In order for people to read effectively, the mental representation of each letter-string must be found in long-term memory. The aim of this project is to more fully understand the nature of proficient visual word recognition with a particular focus on the way in which the form of the word is mentally stored and retrieved during the act of reading. A range of issues will be examined from letter position coding through to how words with a complex internal structure are processed, all framed within a unified model of word recognition. An understanding of the mechanisms underlying proficient adult reading is significant and beneficial in that it is expected to provide a framework for guiding both reading acquisition and reading improvement programs.Read moreRead less
