Diet influences the selective advantage of mitochondrial DNA mutations. This project aims to examine critical mechanisms that affect mitochondrial DNA variation within species. It aims to test the hypothesis that mitochondrial DNA haplotypes have the potential to be under nutritionally induced balancing selection as a consequence of cellular signalling and/or Adenosine triphosphate (ATP) production by mitochondria. Diet can vary both seasonally and geographically and is a key environmental param ....Diet influences the selective advantage of mitochondrial DNA mutations. This project aims to examine critical mechanisms that affect mitochondrial DNA variation within species. It aims to test the hypothesis that mitochondrial DNA haplotypes have the potential to be under nutritionally induced balancing selection as a consequence of cellular signalling and/or Adenosine triphosphate (ATP) production by mitochondria. Diet can vary both seasonally and geographically and is a key environmental parameter that influences the ability of a species to colonise new habitats. The project plans to characterise the functional links between specific mitochondrial DNA haplotypes, mitochondrial functions and organismal traits. The expected outcome is a more precise grasp of the processes influencing genetic variation within and among species, which would inform current issues in ecology and genetics.Read moreRead less
Using genetics to recover Australia's lost history. This project aims to use historic hair samples collected by anthropological expeditions in the early 20th Century to generate the first genetic map of Aboriginal Australia – in order to reconstruct Australia’s pre-European genetic and cultural past.

This project aims to use historic hair samples collected by anthropological expeditions in the early 20th Century to generate the first genetic map of Aboriginal Australia – in order to reconstruct Australia’s pre-European genetic and cultural past. The map and the detailed contextual and genealogical information from museum archives will assist Aboriginal communities and individuals to reconstruct their personal and family history and trace ancestry and augment oral or written records. The combination of cutting-edge science, detailed archival research, and a comprehensive family outreach and reporting program will be a step change in assisting Australia’s reconciliation process, the Stolen Generation, and repatriation of Indigenous remains.Read moreRead less
Genomics for persistence of Australian freshwater fish. Biodiversity faces an unpredictable cocktail of impacts and global environmental change, against which the best insurance is genetic diversity. We will develop genomic measures of ecological-genetic functions and evolutionary potential for managing Australian freshwater fish.

This industry-driven project aims to assemble a strategic research alliance to generate and apply knowledge to a highly significant fisheries resource. It involves collaboration between the five major state government fisheries agencies in Australia, the New Zealand’s Crown Research Institute for seafood and two Australian labs with leadership in fish genetics and genomics. It expects to generate and integrate genomic, environmental and phenotypic datasets for snapper populations from across vast coastal regions of the two countries. The outcomes should substantially enhance intra- and inter-jurisdictional fisheries management and aquaculture initiatives, providing commercial, social and environmental benefits for many stakeholders.Read moreRead less
The impact of severe bushfires on the ecology, demography and genetics of frogs in the Victorian Kinglake region. The February 2009 bushfires in Victoria devastated many communities, and also had a profound impact on wildlife species. This research is aimed at measuring the impact of these fires on frogs in the Kinglake region. It will provide a range of national benefits, including a better understanding of the effects of wildfire on native species and their habitats, information to help plan c ....The impact of severe bushfires on the ecology, demography and genetics of frogs in the Victorian Kinglake region. The February 2009 bushfires in Victoria devastated many communities, and also had a profound impact on wildlife species. This research is aimed at measuring the impact of these fires on frogs in the Kinglake region. It will provide a range of national benefits, including a better understanding of the effects of wildfire on native species and their habitats, information to help plan conservation efforts for frogs, and a vital connection with local landowners; some of whom lost their homes in the fires but were still concerned about the wellbeing of frogs in the area. Australia is a fire-prone country, and this project will help develop responses to the threats posed by the expected increase in the frequency and intensity of fires in southern Australia.Read moreRead less
Evolution of the unique fauna of the Great Artesian Basin mound springs: the impact of aridification and climate change. The mound springs of the Great Artesian Basin represent one of Australia's most unique environments and are of national biodiversity, cultural and economic significance. Their conservation is a major issue following listing of the springs as a threatened ecological community. As economic productivity in the GAB intensifies, the mound springs are under increasing threat from es ....Evolution of the unique fauna of the Great Artesian Basin mound springs: the impact of aridification and climate change. The mound springs of the Great Artesian Basin represent one of Australia's most unique environments and are of national biodiversity, cultural and economic significance. Their conservation is a major issue following listing of the springs as a threatened ecological community. As economic productivity in the GAB intensifies, the mound springs are under increasing threat from escalating groundwater use. The results of this study on the evolution of two crustacean groups will provide significant biological information for management plans, facilitating conservation of mound springs communities, and helping to understand the impacts of water extraction and climate change on this unique habitat.Read moreRead less
Rediscovering Aboriginal dispersal pathways. This project aims to use cutting-edge and transdisciplinary tools in partnership with Aboriginal people to rediscover deliberate prehistoric plant dispersal pathways along the Australian east coast. By working on three unrelated species with similar disjunct distributions, expected outcomes include detecting significant ‘cultural’ vegetation patterns that will challenge current assumptions about 'natural' plant distributions. New associations between ....Rediscovering Aboriginal dispersal pathways. This project aims to use cutting-edge and transdisciplinary tools in partnership with Aboriginal people to rediscover deliberate prehistoric plant dispersal pathways along the Australian east coast. By working on three unrelated species with similar disjunct distributions, expected outcomes include detecting significant ‘cultural’ vegetation patterns that will challenge current assumptions about 'natural' plant distributions. New associations between plant biogeography and deliberate Aboriginal manipulation of Australian environments will benefit cultural heritage, land management and restoration initiatives.Read moreRead less
Potential of gene drives to eliminate incursions of Drosophila suzukii. This project aims to test the efficacy and evolutionary stability of different types of gene drives, and model whether gene drives can be used to eliminate incursions of Drosophila suzukii into Australia. It is now possible to use genome editing technology to alter populations of organisms using ‘gene drives’.

This project aims to test the efficacy and evolutionary stability of different types of gene drives, and model whether gene drives can be used to eliminate incursions of Drosophila suzukii into Australia. It is now possible to use genome editing technology to alter populations of organisms using ‘gene drives’. Multiple strategies have been conceived with a major distinction between those that aim to eliminate populations versus those that aim to modify populations. This project will examine these strategies in two fly species, the model, Drosophila melanogaster and the devastating pest of horticulture, Drosophila suzukii. The project expects to assess a gene drive strategy to control the invasive pest that threatens the Australian soft-skinned fruit industries.Read moreRead less
Using fire to manage biodiversity in fragmented landscapes. Using fire to manage biodiversity in fragmented landscapes. This project intends to develop a conservation management tool for use in fire-prone fragmented landscapes to reverse biodiversity loss. It will address two critical knowledge gaps: the combined effects of fire and fragmentation on animal movement, and the implications of current and future fire regimes for native animal populations.

This project intends to develop a conservation management tool for use in fire-prone fragmented landscapes to reverse biodiversity loss. It will address two critical knowledge gaps: the combined effects of fire and fragmentation on animal movement, and the implications of current and future fire regimes for native animal populations. Land-use change has severely fragmented 40% of Australia’s natural landscapes, resulting in loss of habitat for native biodiversity. Remaining habitat fragments are at risk from increases in the frequency and intensity of fire, which also threatens biodiversity. The anticipated outcome is a conservation management tool that is readily transferable to any fire-prone system.Read moreRead less
Genomics and mixed source populations in wildlife translocations. Translocation is a conservation strategy to help the plight of endangered species, and is becoming increasing important to mitigate against climate change. However translocations often fail. Theory suggests mixing individuals from different source populations would benefit species' genomic diversity and potentially success rates, however this is untested in animals. Also unclear is what parts of the genome are important for mitiga ....Genomics and mixed source populations in wildlife translocations. Translocation is a conservation strategy to help the plight of endangered species, and is becoming increasing important to mitigate against climate change. However translocations often fail. Theory suggests mixing individuals from different source populations would benefit species' genomic diversity and potentially success rates, however this is untested in animals. Also unclear is what parts of the genome are important for mitigating against climate change. Using an endangered lizard model, this project aims to understand how to best start new populations by 1) providing the first empirical test in terrestrial vertebrates of using mixed source populations; and 2) uncovering regions of the genome important for considering in translocations.Read moreRead less
