This project will inform the community about factors that affect the psychological, physical, academic, and employment outcomes of emerging adults. It will improve our knowledge of why some young people do not reach their full potential. The project will provide a comprehensive assessment of factors associated with well-being across several domains. It will better equip and assist professionals to identify early those youth at risk of having poor psychological, health, and employment prospects post-school. The project will inform the development of intervention programs for young people and maximise their overall adjustment and well-being several years later.Read moreRead less
Lamarckian lizards: novel integration of telomere epigenetics, free radicals and innate antioxidants in condition-dependant sexual signal evolution. In 2009, the Nobel Prize in physiology was awarded Drs. Blackburn, Greider and Szostak for discoveries on telomeres. This project will investigate how telomeres not only cap chromosomes from destruction by free radicals, but also have a key role in life itself, in their influence on ageing, longevity, ornaments and lifetime reproductive success.
Female multiple mating and the evolutionary origins of complex societies. This project plans to connect micro-evolutionary processes with macro-evolutionary change to provide a unified understanding of why animals live together. Evolutionary transitions to and from complex social behaviour appear linked to female multiple mating (polyandry). However, the causal pathway by which variation in polyandry results in the emergence and diversification of sociality is yet to be established. Using a vert ....Female multiple mating and the evolutionary origins of complex societies. This project plans to connect micro-evolutionary processes with macro-evolutionary change to provide a unified understanding of why animals live together. Evolutionary transitions to and from complex social behaviour appear linked to female multiple mating (polyandry). However, the causal pathway by which variation in polyandry results in the emergence and diversification of sociality is yet to be established. Using a vertebrate system we aim to integrate empirical, theoretical and comparative approaches to show: the ecological causes of individual variation in female polyandry; its effect on social behaviours that promote social complexity at the population level; and how this corresponds to divergence in social complexity across species.Read moreRead less
Does mother know best? Unifying proximate causation and ultimate explanation in mammalian sex allocation. The study of parental effects is a fundamental area in evolutionary ecology, but is characterised by poor integration of theory (ultimate causation) and physiology (proximate causation). This is true in sex allocation research that focuses almost exclusively on ultimate causation without integrating the physiological mechanisms for sex ratio adjustment. Using a combination of experiments and ....Does mother know best? Unifying proximate causation and ultimate explanation in mammalian sex allocation. The study of parental effects is a fundamental area in evolutionary ecology, but is characterised by poor integration of theory (ultimate causation) and physiology (proximate causation). This is true in sex allocation research that focuses almost exclusively on ultimate causation without integrating the physiological mechanisms for sex ratio adjustment. Using a combination of experiments and modelling, the project addresses this gap in understanding mammalian sex allocation, specifically: the lack of known mechanism; the connection between proximate mechanistic explanation and adaptive fitness explanations; and, knowledge on constraints. This project argues that one mechanism, pre-implantation glucose levels, links adaptive hypotheses with proximate causation. Read moreRead less
Plasticity and the origins of family. This project aims to answer the question of how family life evolved. Humans and many animals live in stable family groups because of the benefits of cooperation. Surprisingly, we have a very poor understanding of how family living initially evolved. This project will experimentally determine how simple responses to environmental change have driven the evolution of family living and thereby refine theories for understanding social evolution more generally. ....Plasticity and the origins of family. This project aims to answer the question of how family life evolved. Humans and many animals live in stable family groups because of the benefits of cooperation. Surprisingly, we have a very poor understanding of how family living initially evolved. This project will experimentally determine how simple responses to environmental change have driven the evolution of family living and thereby refine theories for understanding social evolution more generally. This information will be useful to environmental policy makers that need to consider the role of environmental change in managing and conserving viable populations.Read moreRead less
Maternal effects and sex allocation: an integrated approach. This project will produce research of a high international standard combining a number of key fields in evolution and ecology. The team we have assembled provides a link between Australian-based researchers and leading overseas theoreticians facilitating integration between evolutionary theory and empirical research on the unique Australian fauna. Furthermore, while climate change is identified as a priority area for research, Australi ....Maternal effects and sex allocation: an integrated approach. This project will produce research of a high international standard combining a number of key fields in evolution and ecology. The team we have assembled provides a link between Australian-based researchers and leading overseas theoreticians facilitating integration between evolutionary theory and empirical research on the unique Australian fauna. Furthermore, while climate change is identified as a priority area for research, Australia typically lacks the history of long-term phenological monitoring that is required to understand climate change impacts. This project takes an important step towards addressing this shortcoming.Read moreRead less
Methods of Topology: Boundary, Surface and the Inner/Outer in Kant and Wittgenstein. Ways of 'inclusion' vs. 'exclusion' are of basic and pivotal significance in social and political scenarios, e.g. of establishing identities and conducting intra- and transnational discourses. At the root of these discourses lies a vague and implicit 'metaphysics' of the nature of the 'internal', of distinction and discrimination, fostered by intuitions of alleged privileged access to the 'inner'. The project ha ....Methods of Topology: Boundary, Surface and the Inner/Outer in Kant and Wittgenstein. Ways of 'inclusion' vs. 'exclusion' are of basic and pivotal significance in social and political scenarios, e.g. of establishing identities and conducting intra- and transnational discourses. At the root of these discourses lies a vague and implicit 'metaphysics' of the nature of the 'internal', of distinction and discrimination, fostered by intuitions of alleged privileged access to the 'inner'. The project has direct impact on the de-mystification of these socially central notions, its institutional misapprehensions and cultural implications. The project is a paradigm case of how thorough philosophical analysis can yield concrete results, contributing to an understanding of personal, social and political boundaries and demarcations.Read moreRead less
Neural correlates of performance trade-offs and interference in dual-task performance. Our daily lives are characterised by our ability to produce and sustain a wide range of different movement patterns and to deliberately change patterns as the situation demands. In this project we seek to understand the relationship between brain processes, attentional demands, and the control and learning of coordinated behaviour. A further aim will be to examine how this relationship may be altered as a re ....Neural correlates of performance trade-offs and interference in dual-task performance. Our daily lives are characterised by our ability to produce and sustain a wide range of different movement patterns and to deliberately change patterns as the situation demands. In this project we seek to understand the relationship between brain processes, attentional demands, and the control and learning of coordinated behaviour. A further aim will be to examine how this relationship may be altered as a result of aging, degenerative disease, or brain damage. This research will provide a foundation upon which rehabilitation strategies can be developed for the movement impaired.Read moreRead less
Molecular aggression: variation and heritability of the levels of reactive oxygen species, and their effects on the evolution of life histories in the wild. Three areas of biology have intrigued every generation since Aristotle (c. 300 BC)- sex, embryology, and ageing. This proposal targets all three of these areas with a special focus on aspects of ageing. In particular, we assess how 'free radicals', so often identified in our food and wine for good and bad, exert selection on living organisms ....Molecular aggression: variation and heritability of the levels of reactive oxygen species, and their effects on the evolution of life histories in the wild. Three areas of biology have intrigued every generation since Aristotle (c. 300 BC)- sex, embryology, and ageing. This proposal targets all three of these areas with a special focus on aspects of ageing. In particular, we assess how 'free radicals', so often identified in our food and wine for good and bad, exert selection on living organisms and whether resistance (and defense) towards free radicals may drive evolution of ageing in the wild, its trade offs with fertility and fecundity, and how it is influenced by sexual or non-sexual reproduction. In spite of excellent work in the laboratory, this is the first attempt to do this in 'the real world' and will extend Australia's excellent reputation in evolutionary biology.Read moreRead less
Facilitatory and inhibitory mechanisms during interlimb coordination in young and older adults. The project seeks to understand how people coordinate their limbs and the factors which limit and enhance this capacity. This is of critical importance because coordination is a dominant deficit in aging and in patients suffering brain insult and neurodegenerative diseases. Disruption of this capacity compromises individual work productivity, mobility and independence. Proficient motor functioning is ....Facilitatory and inhibitory mechanisms during interlimb coordination in young and older adults. The project seeks to understand how people coordinate their limbs and the factors which limit and enhance this capacity. This is of critical importance because coordination is a dominant deficit in aging and in patients suffering brain insult and neurodegenerative diseases. Disruption of this capacity compromises individual work productivity, mobility and independence. Proficient motor functioning is an important lifestyle factor as humans age and deficits in coordinated muscle activity will increase the risk of falls which are the leading cause of injury in elderly adults. Identification of changes in brain processes involved in interlimb coordination will allow for the development of strategies to improve motor functions in the aged.Read moreRead less
