Uncovering the processes underlying human category learning. There is a pervasive belief that complex tasks can somehow be learned via a 'smart' implicit or procedural learning mechanism, which operates independently of memory and attention. This idea has important implications for our understanding of cognition. If true, there seems little point in providing explicit instruction in such tasks, and efforts to do so are, at best, wasted time and, at worst, detrimental to the learning process. Th ....Uncovering the processes underlying human category learning. There is a pervasive belief that complex tasks can somehow be learned via a 'smart' implicit or procedural learning mechanism, which operates independently of memory and attention. This idea has important implications for our understanding of cognition. If true, there seems little point in providing explicit instruction in such tasks, and efforts to do so are, at best, wasted time and, at worst, detrimental to the learning process. This project will provide much-needed scrutiny of this idea and will help not only to re-orient our understanding of how we deal with complex information, but will also highlight issues about data interpretation that are fundamental for the research and wider communities.Read moreRead less

Female roles during postcopulatory sexual selection. The project will evaluate the importance of postcopulatory sexual selection in the guppy, a polyandrous species of livebearing fish. The use of artificial insemination, which experimentally controls the relative contribution of sperm from competing males (as well as other confounding effects), will facilitate a powerful test of recent theoretical predictions in evolutionary biology. The project will enable me to distinguish between competing h ....Female roles during postcopulatory sexual selection. The project will evaluate the importance of postcopulatory sexual selection in the guppy, a polyandrous species of livebearing fish. The use of artificial insemination, which experimentally controls the relative contribution of sperm from competing males (as well as other confounding effects), will facilitate a powerful test of recent theoretical predictions in evolutionary biology. The project will enable me to distinguish between competing hypotheses for postcopulatory paternity bias following female multiple mating (sperm competition, cryptic female choice, genetic compatibility) and provide additional insights into the selective forces promoting the evolution of female promiscuity.Read moreRead less
Mid-rotation diagnosis and management options for correction of water and nutrient deficiencies in plantation-grown eucalypts. This research will improve productivity of bluegum plantations by improving current diagnostic techniques (foliage and soil analysis) for nutrient disorders and the supply of water. Using a novel phloem sampling and analysis technique, we will develop a nutrient (e.g. N, P) and water diagnosis procedure that is quick, cheap, robust and reliable for field use. A major in ....Mid-rotation diagnosis and management options for correction of water and nutrient deficiencies in plantation-grown eucalypts. This research will improve productivity of bluegum plantations by improving current diagnostic techniques (foliage and soil analysis) for nutrient disorders and the supply of water. Using a novel phloem sampling and analysis technique, we will develop a nutrient (e.g. N, P) and water diagnosis procedure that is quick, cheap, robust and reliable for field use. A major innovation will be distinguishing the effects of shortages of water on growth from those of other growth influences. Overall, this project will provide a highly significant theoretical, conceptual and practical advance in mid-rotation, diagnostics for plantations with considerable commercial promise.Read moreRead less
Australian savannah landscapes: past, present and future. Australian savannahs are productive and culturally and biologically significant landscapes but are vulnerable to climate change. The project will determine savannah function (carbon and water balance) for the present and assess how sensitive they have been to past climate variability. The project will then address how they may respond to future climate change.
Turf Wars: fighting the new battle facing blue forests. This project aims to use ecological models and field experiments to uncover drivers and critical thresholds for turf expansion. Habitat loss is a leading threat to goods and services from the oceans. Globally, kelp forests are collapsing and being replaced by persistent unwanted algal ‘turfs’. Understanding of this habitat shift is rudimentary, and solutions to mitigate the impacts virtually non-existent. Through stress experiments and geno ....Turf Wars: fighting the new battle facing blue forests. This project aims to use ecological models and field experiments to uncover drivers and critical thresholds for turf expansion. Habitat loss is a leading threat to goods and services from the oceans. Globally, kelp forests are collapsing and being replaced by persistent unwanted algal ‘turfs’. Understanding of this habitat shift is rudimentary, and solutions to mitigate the impacts virtually non-existent. Through stress experiments and genomic analyses, this project aims to discover resilient kelps that promote forest persistence under stress. By expanding our understanding of critical habitat transitions, and exploring new solutions, this project aims to enhance our capacity to respond to the ongoing degradation of Australia’s Great Southern Reef.Read moreRead less
Global threats to kelp forests from heatwaves, herbivores and diseases. This project aims to understand the mechanisms behind climate-mediated declines in kelp. Ocean warming causes the collapse of valuable temperate kelp forests globally and on both sides of Australia, but it is unknown if this is because of direct physiological effects from temperature or the indirect effects of changes in species interactions. This project will compare the direct effects of marine heatwaves to the indirect ef ....Global threats to kelp forests from heatwaves, herbivores and diseases. This project aims to understand the mechanisms behind climate-mediated declines in kelp. Ocean warming causes the collapse of valuable temperate kelp forests globally and on both sides of Australia, but it is unknown if this is because of direct physiological effects from temperature or the indirect effects of changes in species interactions. This project will compare the direct effects of marine heatwaves to the indirect effects of range-shifting tropical herbivores and pathogens for the kelp forests of the Great Southern Reef, one of Australia’s largest coastal ecosystems. This project will generate knowledge underpinning adaptation strategies for these critical ecosystems, and could enhance the capacity to respond to degradation of these natural assets.Read moreRead less
Marine heatwaves drive loss of genetic diversity and selection in kelps. This project aims to unravel where and when marine heatwaves drive loss of genetic diversity and rapid directional selection in kelp forests. Although the devastating ecological impacts of marine heatwaves are well studied, empirical understanding of how marine heatwaves impact underlying evolutionary processes including adaptive capacity and resilience is lacking. This research will use a powerful combination of innovative ....Marine heatwaves drive loss of genetic diversity and selection in kelps. This project aims to unravel where and when marine heatwaves drive loss of genetic diversity and rapid directional selection in kelp forests. Although the devastating ecological impacts of marine heatwaves are well studied, empirical understanding of how marine heatwaves impact underlying evolutionary processes including adaptive capacity and resilience is lacking. This research will use a powerful combination of innovative heatwave analyses, cutting-edge genomics and physiological experiments to fill these knowledge gaps and represents a step change in our understanding of how kelp respond and adapt in multi-stressor seascapes. Results will pave the way for development of novel mitigation strategies to future-proof marine management. Read moreRead less
