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
Is regressive evolution associated with loss of gene function in subterranean animals? This project aims to investigate a fundamental biological process: the evolutionary basis for how non-functional characters, such as eyes in subterranean animals, are lost. It will use a unique model system based on eyeless water beetles, and utilise novel new genomic tools to test whether loss of characters results from gene inactivation.
Identifying the diversity and evolution of loci associated with adaptation to aridity/heat and salinity in ancient cereal crops. This project will use ancient grains of wheat, barley and rye to find 'lost' genetic diversity at key genes associated with resistance to aridity, salt and disease. This project will make the proteins of key genes, and study their interaction with the environment over time by measuring ions in the grains to reveal the ancient environmental conditions.
