This work will strengthen both the theoretical framework and the local knowledge base for sustainable timber production from natural forests, and for habitat restoration programs (National Research Priority 1.5: Sustainable Use of Australia's Biodiversity). These same advances of global and local relevance will also enable better quality input into models predicting vegetation dynamics under climate change scenarios (Research Priority 1.7: Responding to climate change & variability). Furthermore, by clarifying relationships of shade tolerance with other stress-tolerance strategies, this work will help us understand the evolutionary potential of local floras to respond to global change.Read moreRead less

The tuneable diode laser system will facilitate projects with major environmental benefits to Australia. Projects will provide major insights into Australia's CO2 balance. This will improve our ability to predict whether ecosystems are net sources or sinks for CO2 -- information that underpins Australia's greenhouse gas balance. The tuneable diode laser system will also benefit Australia's economy via enhancing understanding of agricultural and forest production, a key portion of our GDP. These economic benefits will stem from new knowledge about the limitations to plant growth and the water-use efficiency of plants. Read moreRead less
Integrating human operators into large-scale sensor networks. Information awareness is critical in many applications of national importance: from bush fire fighting and defence to transportation and health care. These applications involve tasks in which timely delivery and fusion of heterogeneous information streams is of critical importance. They can all benefit from the use of robotic and embedded sensor networks considered in this project. Human operators, acting as users or supervisors, will ....Integrating human operators into large-scale sensor networks. Information awareness is critical in many applications of national importance: from bush fire fighting and defence to transportation and health care. These applications involve tasks in which timely delivery and fusion of heterogeneous information streams is of critical importance. They can all benefit from the use of robotic and embedded sensor networks considered in this project. Human operators, acting as users or supervisors, will remain at the centre of these systems. The technology and algorithms developed in this project will efficiently structure information exchange between humans and sensor networks. Establishing Australian leadership in this fast-evolving high-technology field will spur growth and job creation.Read moreRead less
Operator Decision Modelling in Autonomous Systems. The incorporation of humans as decision-makers into a complex system comprising of many autonomous agents is becoming increasingly important in areas such as defence, search-and-rescue, special emergency services, bush-fire and ecology management. This project will address how human decisions are made in such systems through the formulation and demonstration of innovative algorithms which model the operator decision making process.

The incorporation of humans as decision-makers into a complex system comprising of many autonomous agents is becoming increasingly important in areas such as defence, search-and-rescue, special emergency services, bush-fire and ecology management. This project will address how human decisions are made in such systems through the formulation and demonstration of innovative algorithms which model the operator decision making process. Generating solutions to this increasingly important area will provide Australia's industry and community services the necessary knowledge for deploying such systems and thus improving service effectiveness, as well as the implementation of autonomous systems into new areas and thus increasing economic growth.Read moreRead less
Investigating Linguistic Factors Associated with Stuttering in Cantonese. The aim of this research is to gain new knowledge about the cause of stuttering. The project is a collaboration between experts in stuttering in Australia and Hong Kong. Despite decades of study, the cause of stuttering is still not well understood. Research in English has suggested that changes in emphasis from syllable to syllable can trigger individual moments of stuttering. However, Cantonese is very different from Eng ....Investigating Linguistic Factors Associated with Stuttering in Cantonese. The aim of this research is to gain new knowledge about the cause of stuttering. The project is a collaboration between experts in stuttering in Australia and Hong Kong. Despite decades of study, the cause of stuttering is still not well understood. Research in English has suggested that changes in emphasis from syllable to syllable can trigger individual moments of stuttering. However, Cantonese is very different from English, being a tonal and syllabic language, and uncovering the linguistic triggers of stuttering in Cantonese will yield new insight into the complex causality of this disabling condition.Read moreRead less
Initiation of spontaneous fires. This project aims to determine the origin of the initiation reactions that set off the self-heating of wood chips, coal, milk powder and other economically-important materials, leading to spontaneous fires. This project will provide fundamental understanding of the reactions between electronically excited species of oxygen and carbonaceous fuels, with applications to improved safety in wood, mineral and food industries. The outcomes include identification of the ....Initiation of spontaneous fires. This project aims to determine the origin of the initiation reactions that set off the self-heating of wood chips, coal, milk powder and other economically-important materials, leading to spontaneous fires. This project will provide fundamental understanding of the reactions between electronically excited species of oxygen and carbonaceous fuels, with applications to improved safety in wood, mineral and food industries. The outcomes include identification of the initiation mechanisms and development of mechanistic models that include the initiation step of the self-heating process, and development of new technologies for mitigation of spontaneous fires, based on quenching of the initiation reactions.Read moreRead less
Mixed species plantations: does diversity help tropical eucalypts grow faster, better, longer? To test the assumption that mixtures are better than monocultures, using data from experiments (QFRI) and community plantings. Growth rate, habit (form, branching), timber and soil characteristics in Eucalyptus pellita (Red Mahogany) plantings should elucidate whether mixtures:
1. grow (above-ground woody biomass) faster than pure plantings;
2. have straighter trees with smaller branches;
3. improve ....Mixed species plantations: does diversity help tropical eucalypts grow faster, better, longer? To test the assumption that mixtures are better than monocultures, using data from experiments (QFRI) and community plantings.

1. grow (above-ground woody biomass) faster than pure plantings;
2. have straighter trees with smaller branches;
3. improve soil fertility; and whether
4. differences are accentuated in subsequent rotations.
E. pellita has valuable dark-red timber, and is widely planted in north Queensland, despite variable performance (3-30 m3/ha/yr, average 10m3/ha/yr). Analyses will reveal opportunities for conservation outcomes and sustainable timber production.Read moreRead less
Metabolite pools and their implications for plant responses to global change. Australian landscape management faces significant challenges from existing land practices and the effects of climate change. Effective management and targeted remediation requires an understanding of the processes that drive ecosystem function. The development of broadly applicable tools for the monitoring of plant and ecosystem health is therefore of considerable interest.

Australian landscape management faces significant challenges from existing land practices and the effects of climate change. Effective management and targeted remediation requires an understanding of the processes that drive ecosystem function. The development of broadly applicable tools for the monitoring of plant and ecosystem health is therefore of considerable interest. Flexibility in core processes of plant function represents a significant opportunity to develop such tools. With a focus on plant metabolites, this project will characterise how Australian trees alter the allocation of resources to cope with environmental changes and produce metabolite-based selective traits for stress tolerance in Australian trees.

Higher cognition and hemispheric specialization in an avian species: referential and intentional communication. We will discover whether alarm calls of Australian magpies, noted for their outstanding range of vocalisations, are referential (signalling predator type and location) and intentional (vocalised in specific contexts). Such complex communication , once thought to be unique to humans, has been found in some mammals and just one avian species, the domestic chick. This project will be the ....Higher cognition and hemispheric specialization in an avian species: referential and intentional communication. We will discover whether alarm calls of Australian magpies, noted for their outstanding range of vocalisations, are referential (signalling predator type and location) and intentional (vocalised in specific contexts). Such complex communication , once thought to be unique to humans, has been found in some mammals and just one avian species, the domestic chick. This project will be the first such investigation of an avian species in its natural habitat. This is important also because bird and mammalian brains are organised differently and birds offer a unique opportunity to discover whether one hemisphere is specialised for this purpose.Read moreRead less
