Interpreting biological sequence information: untangling hybridisation. Hybridisation is believed to be important during adaptive radiations where species rapidly colonise new niches and respond to new environments, e.g. in times of climate change. This project will create the statistical tools and software required for evolutionary biologists to understand how hybridisation has helped shape the Australian flora.
Community and ecosystem consequences of adaptive evolution in Eucalyptus. There is emerging evidence across plant systems that genes in one species influence biodiversity and the services ecosystems provide, including soil fertility, carbon storage, and pollination. These results suggest that adaptive evolution in plants can lead to change in biodiversity and ecosystem function. If this finding proves to be true, results from this proposal might be critical to future decisions on the ecosystem ....Community and ecosystem consequences of adaptive evolution in Eucalyptus. There is emerging evidence across plant systems that genes in one species influence biodiversity and the services ecosystems provide, including soil fertility, carbon storage, and pollination. These results suggest that adaptive evolution in plants can lead to change in biodiversity and ecosystem function. If this finding proves to be true, results from this proposal might be critical to future decisions on the ecosystem consequences of landscape level selective events. There may be major implications for the rapidly expanding environmental and forestry plantings across Australia and temperate regions of the world where choice of seed source may have far reaching consequences.Read moreRead less
Breaking Gondwana: interplay between tectonics, climate and resources. The project aims to reconstruct 250 million years of landscape evolution in response to rifting and break-up of the Gondwana supercontinent, using the innovative approach of combining regional thermochronology with global plate tectonic models. From these reconstructions, the time-integrated record of exhumation and erosion at the continental margins will be revealed at an unprecedented scale. The main expected outcome will b ....Breaking Gondwana: interplay between tectonics, climate and resources. The project aims to reconstruct 250 million years of landscape evolution in response to rifting and break-up of the Gondwana supercontinent, using the innovative approach of combining regional thermochronology with global plate tectonic models. From these reconstructions, the time-integrated record of exhumation and erosion at the continental margins will be revealed at an unprecedented scale. The main expected outcome will be a deep time archive of the relationships between tectonic forcing, continental erosion and the global climate, which may assist predictions and debate on future climate change. The outcomes will also provide economic benefits as they will inform on the exhumation and preservation of (critical) mineral resources.Read moreRead less
Genetics, genomics and evolution of flowering time control in legumes. Flowering in plants is strongly regulated by environmental factors, with important consequences for their natural distribution and use in agriculture. This project will characterise genes, genetic diversity and molecular mechanisms that control flowering in legumes, contributing to fundamental biology, crop improvement and research training.
Decoding the signals in legume symbioses: investigating the role of plant hormones. Plants form intimate relationships with soil microbes that give plants access to previously unavailable but essential nutrients. Legumes are major Australian crops for fodder, grain and nutrients, and are unique in forming symbioses with both nitrogen-fixing bacteria and with mycorrhizal fungi that supply nutrients such as phosphate. This project aims to determine the role of plant hormones (small, mobile, potent ....Decoding the signals in legume symbioses: investigating the role of plant hormones. Plants form intimate relationships with soil microbes that give plants access to previously unavailable but essential nutrients. Legumes are major Australian crops for fodder, grain and nutrients, and are unique in forming symbioses with both nitrogen-fixing bacteria and with mycorrhizal fungi that supply nutrients such as phosphate. This project aims to determine the role of plant hormones (small, mobile, potent growth regulators) in the formation of these relationships. In particular, the role of interactions between hormones and other novel plant signals will be determined. An insight into the common and divergent roles of hormones in these symbioses is essential to provide new tools to maximise nutrient acquisition.Read moreRead less
Tools for manipulating neuronal activity for behavioural studies. This project aims to develop optogenetic tools neuroscientists can use to better understand brain circuitry and the functional effects of specific neurons on behaviour. Linking the activity of individual neurons in the brain to specific behaviours is a major challenge in neuroscience. Optogenetics achieve this by using light to control the activity of neurons. This has advanced understanding of behaviour and neurocircuitry. This p ....Tools for manipulating neuronal activity for behavioural studies. This project aims to develop optogenetic tools neuroscientists can use to better understand brain circuitry and the functional effects of specific neurons on behaviour. Linking the activity of individual neurons in the brain to specific behaviours is a major challenge in neuroscience. Optogenetics achieve this by using light to control the activity of neurons. This has advanced understanding of behaviour and neurocircuitry. This project is expected to increase understanding of brain function at the cellular and system levels, and advance Australia’s multidisciplinary research capacity in neuroscience, cognitive sciences and nanobiotechnology to ultimately treat neurological disorders.Read moreRead less
