Restoration genetics of five endangered fish species from the Murray-Darling Basin. Extended drought and environmental degradation have caused unprecedented loss of aquatic biodiversity in the Murray-Darling Basin (MDB), Australia's most important agricultural region. This project will reduce the risk of extinction of two endangered and three critically endangered freshwater fish species from the lower MDB.

Extended drought and environmental degradation have caused unprecedented loss of aquatic biodiversity in the Murray-Darling Basin (MDB), Australia's most important agricultural region. This project will reduce the risk of extinction of two endangered and three critically endangered freshwater fish species from the lower MDB. It will provide major benefits to the broader Australian community by addressing government policies regarding sustainable water management in rural areas, biodiversity protection and recovery of threatened species. The study will also increase the research profile of Australia in the international scientific community by improving our understanding about genetic diversity in captive breeding and restoration programs.Read moreRead less

Summary
Understanding adaptation of plants along environmental clines. This project aims to address a key debate on the relative roles of dispersal and selection on adaptation, testing how life history traits determine the magnitude of adaptation. Since dispersal should override selection, this project endeavours to show that plants that strongly disperse will display weaker signals of adaptation but a higher capacity to adapt. The project aims to test these predictions with ecological genomics and func ....Understanding adaptation of plants along environmental clines. This project aims to address a key debate on the relative roles of dispersal and selection on adaptation, testing how life history traits determine the magnitude of adaptation. Since dispersal should override selection, this project endeavours to show that plants that strongly disperse will display weaker signals of adaptation but a higher capacity to adapt. The project aims to test these predictions with ecological genomics and functional genetics at a multi-species scale across climate gradients in South Australia, using a novel design that separates dispersal (isolation-by-distance) from selection (isolation-by-ecology). This understanding will provide improved conservation planning that seeks to restore resilience to biological communities that are under increasing environmental pressures.Read moreRead less
Understanding adaptation to improve conservation of Australian flora. Using the Australian flora as our model, this project aims to tackle a central issue of evolution and conservation - what drives species adaptation? Since dispersal should override selection in populations, we predict that plants that are good dispersers will display weak signals of adaptation, but a higher capacity to adapt, than poorer dispersers. From these expectations we plan to develop a new adaptation guild classificati ....Understanding adaptation to improve conservation of Australian flora. Using the Australian flora as our model, this project aims to tackle a central issue of evolution and conservation - what drives species adaptation? Since dispersal should override selection in populations, we predict that plants that are good dispersers will display weak signals of adaptation, but a higher capacity to adapt, than poorer dispersers. From these expectations we plan to develop a new adaptation guild classification, and test predictions using ecological genomics and functional genetics at a continental and multi-species scale. In addition to progressing a central tenet of evolutionary biology, this project aims to improve seed sourcing and biodiversity management, readily applicable to plants that can be quickly classified by life history traits.Read moreRead less

Summary
Next generation enhancement of the South Australian regional facility for molecular ecology and evolution. The new equipment will enhance opportunities for innovative research in basic biology, archaeological, agricultural, biomedical, forensic and environmental sciences. This research is critical for monitoring the nature and extent of environmental change and developing strategies to promote adaptation by species to future climate change.
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’. Multiple strategies have been conceived with a major distinction between those that aim to eliminate populations ver ....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’. 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
