Predicting the movement speeds of animals. The project seeks to reveal how marsupials modify their movement patterns and speeds as they navigate risky environments, and show how movement contributes to vulnerability and resilience. Movement is central to animal behaviour and the survival of species, because it underlies feeding, mating and the ability to escape from predators. However, we lack a framework for predicting how fast animals should move through their habitats given their needs to con ....Predicting the movement speeds of animals. The project seeks to reveal how marsupials modify their movement patterns and speeds as they navigate risky environments, and show how movement contributes to vulnerability and resilience. Movement is central to animal behaviour and the survival of species, because it underlies feeding, mating and the ability to escape from predators. However, we lack a framework for predicting how fast animals should move through their habitats given their needs to conserve energy, avoid detection by predators and minimise risks of injury or death. This project aims to develop mathematical models to predict how fast animals should move and then test these predictions using native species of conservation concern. This is expected to extend the field of performance ecology as well as inform management strategies for vulnerable marsupials.Read moreRead less
The nature and consequences of environmentally-generated phenotypic variation in natural populations. The ambient environment can generate both heritable and non-heritable variation in individual traits, but the role of such variation in evolution is poorly understood. This project will use a powerful model organism, the Australian neriid flies, to elucidate the evolutionary implications of environmentally-generated variation.
Testing our knowledge on the dawn of animal life: evidence from the fossil record against modern ecological and morphological analogues. The Cambrian 'Explosion', half a billion years ago, is regarded as one of the most important events in the history of the Earth, when most major animal groups first appear in the rock record, and for which South Australia has recently become a significant source of spectacular fossils. However, important questions remain regarding their Ediacaran roots, the spe ....Testing our knowledge on the dawn of animal life: evidence from the fossil record against modern ecological and morphological analogues. The Cambrian 'Explosion', half a billion years ago, is regarded as one of the most important events in the history of the Earth, when most major animal groups first appear in the rock record, and for which South Australia has recently become a significant source of spectacular fossils. However, important questions remain regarding their Ediacaran roots, the speed of evolution at the time, and the environments in which the radiation took place. Studying the fossil evidence in the light of present-day ecological frameworks, and in comparison with modern behavioural and morphological analogues, as well as living relatives, can help us better assess our understanding of this first radiation of animals.Read moreRead less
Long noncoding RNAs and their regulatory roles in epigenetic control of gene expression in plants. Epigenetic control of gene expression plays a critical role in development, environmental adaptation, stress response and disease resistance in plants, but its molecular basis remains largely unknown. The proposed study should contribute to the emerging field of epigenetics by discovering new regulatory noncoding RNAs involved in epigenetic mechanisms in plants. These new discoveries could potentia ....Long noncoding RNAs and their regulatory roles in epigenetic control of gene expression in plants. Epigenetic control of gene expression plays a critical role in development, environmental adaptation, stress response and disease resistance in plants, but its molecular basis remains largely unknown. The proposed study should contribute to the emerging field of epigenetics by discovering new regulatory noncoding RNAs involved in epigenetic mechanisms in plants. These new discoveries could potentially provide new opportunities and platforms for improving the performance, yield and quality of crop plants. The proposed study is therefore consistent with the national research priority goals such as breakthrough science, frontier technologies and promoting an innovation culture.Read moreRead less
Enhancing wellbeing over the family life course. This project aims to investigate the impact of family life transitions, such as relationship formation and dissolution or births, on wellbeing over the life course. It will do this by analysing data following people over time and will provide information about the negative and positive effects of family transitions for wellbeing, track changes in wellbeing before, during and after transitions, and highlight the intersections of the family life cou ....Enhancing wellbeing over the family life course. This project aims to investigate the impact of family life transitions, such as relationship formation and dissolution or births, on wellbeing over the life course. It will do this by analysing data following people over time and will provide information about the negative and positive effects of family transitions for wellbeing, track changes in wellbeing before, during and after transitions, and highlight the intersections of the family life course with gender, age and socioeconomic status. This will considerably enhance understandings of wellbeing over the family life course, providing insights for targeted policies and interventions to improve health and wellbeing.Read moreRead less

Plant immunity to fungal and bacterial pathogens. Since 2003, the Australian wheat crop has been threatened by a continuing stripe rust epidemic, which has required an additional production expense of at least $100 million per annum in fungicides. This Australian National University (ANU) - Commonwealth Scientific and Industrial Research Organisation (CSIRO) joint proposal aims to exploit the next-generation genome sequencing and associated bioinformatic and proteomic methods which are poised to ....Plant immunity to fungal and bacterial pathogens.

This Australian National University (ANU) - Commonwealth Scientific and Industrial Research Organisation (CSIRO) joint proposal aims to exploit the next-generation genome sequencing and associated bioinformatic and proteomic methods which are poised to revolutionise biology to investigate the wheat-fungus interaction. We will develop new effective approaches for environmentally benign stripe rust control based on new knowledge about how this fungus causes disease and avoids the wheat's immune surveillance system.Read moreRead less
A community-based approach to the problem of underage drinking. This project will aim to reduce the frequency and amount of alcohol consumption, and alcohol-related harms, among young people aged 12-17 years by addressing social norms regarding underage alcohol consumption. Using a multi-component intervention it will engage the Illawarra community in strategies to encourage and empower young people not to drink.
Mental health, job quality and workforce participation: evidence from population health research to address complex problems and conflicting policies. Mental disorders such as depression are a major cause of disability. Improving mental health can increase productivity and workforce participation. However, the psychosocial quality of work is a factor that overlays the relationship between work and health. Poor quality work (for example, unreasonable time pressure, insecurity) increases the risk ....Mental health, job quality and workforce participation: evidence from population health research to address complex problems and conflicting policies. Mental disorders such as depression are a major cause of disability. Improving mental health can increase productivity and workforce participation. However, the psychosocial quality of work is a factor that overlays the relationship between work and health. Poor quality work (for example, unreasonable time pressure, insecurity) increases the risk of poor mental health, absenteeism, and exit from the workforce. This project will analyse data following people over time to investigate the long-term health and employment consequences of poor psychosocial job quality, and consider the special case of mature age workers. It will identify those individuals at greatest risk, and factors that can buffer against the adverse effects of poor quality work.Read moreRead less
