Provision of water for agricultural, industrial and residential use is becoming increasingly difficult in Australia. By determining the need for important migratory fish species to have access to marine conditions, this project aims to assist managers to identify river systems where changing flow patterns will be particularly detrimental. The project will provide information about the need for artificial opening of estuary mouths, fish ladders and other practical means to ensure the continued survival of these species.

This project will use DNA data to address fundamental questions about the origin and maintenance of biodiversity in a popular and widely distributed fish group. From a conservation perspective, the project will produce a benchmark about management of fish resources. We will investigate questions related to important conservation issues (including the recovery plan of a nationally threatened species) and the management of stocking activities in recreational fisheries of coastal and inland waters. The latter is particularly relevant to rural communities since they provide both social and economic benefits to rural people.Read moreRead less
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. It will provide major benefits to the broader Australian community by addressing governme ....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. 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

This project aims to provide rapid diagnostic detection of environmental change in aquatic ecosystems at reduced cost. Next-generation sequencing (NGS) can transform monitoring of aquatic ecosystems by identifying many species in multiple biological samples. This project aims to use NGS technology to identify macroinvertebrate species as biological indicators in urban freshwater ecosystems to provide more rapid, sensitive and cost-effective monitoring compared to traditional methods. The project uses DNA barcodes that identify species to detect species in samples processed with NGS. The project also plans to use previously collected samples to explore species diversity and detect indicator species.Read moreRead less
Subterranean invertebrate communities of arid zone Western Australia: diversity, assessment and food-web structure. The diverse and unique subterranean fauna associated with aquifers of the Western Australia arid zone is potentially threatened by water extraction, mining and other human impacts. This project aims to apply a powerful combination of molecular genetic analyses and compound specific isotope analyses to study, for the first time, the food web structure and source of energy of these g ....Subterranean invertebrate communities of arid zone Western Australia: diversity, assessment and food-web structure. The diverse and unique subterranean fauna associated with aquifers of the Western Australia arid zone is potentially threatened by water extraction, mining and other human impacts. This project aims to apply a powerful combination of molecular genetic analyses and compound specific isotope analyses to study, for the first time, the food web structure and source of energy of these groundwater ecosystems. The project aims to also develop novel procedures for monitoring their biodiversity using environmental DNA within the groundwater. The results will provide crucial information for the management of groundwater, and conservation of their associated ecosystems, and significantly improve the rigour of long-term environmental monitoring.Read moreRead less
The Maintenance of Genetic Variation by Antagonistic Sexual Selection. The principle outcomes of my proposed research are fundamental knowledge, training of young scientists and the improvement of Australia's research capacity and profile. My research will have a major impact on two major branches of evolutionary biology that are seldom integrated - sexual selection and quantitative genetics. My research will enable me to establish myself as an independent researcher. Moreover, my collaborations ....The Maintenance of Genetic Variation by Antagonistic Sexual Selection. The principle outcomes of my proposed research are fundamental knowledge, training of young scientists and the improvement of Australia's research capacity and profile. My research will have a major impact on two major branches of evolutionary biology that are seldom integrated - sexual selection and quantitative genetics. My research will enable me to establish myself as an independent researcher. Moreover, my collaborations with one of the leading research laboratories in the UK, will teach me several modern techniques that I can disseminate to Australian students participating on the proposed project.Read moreRead less
Putting sexual selection in a life-history context: What is meant by genetic quality? Theories of sexual signalling have been developed largely without reference to life-history theory and quantitative genetics. We will test recent theory that shows the costs of signals are best measured in units of future survival and reproduction. In a series of field and laboratory experiments on the cricket Teleogryllus commodus, we will test the idea that the "male genetic quality" referred to by good-genes ....Putting sexual selection in a life-history context: What is meant by genetic quality? Theories of sexual signalling have been developed largely without reference to life-history theory and quantitative genetics. We will test recent theory that shows the costs of signals are best measured in units of future survival and reproduction. In a series of field and laboratory experiments on the cricket Teleogryllus commodus, we will test the idea that the "male genetic quality" referred to by good-genes models of sexual selection is quality in the general ability to acquire resources, rather than in how resources are allocated among fitness components.Read moreRead less
The Geometry of Genetic Limits to Evolutionary Change. Genetic limits to evolutionary change are a fundamental issue for plant and animal improvement, as well as understanding how natural populations may respond to human-induced changes such as habitat degradation and climate change. Because we still know very little about how genetic variation is distributed among the multiple traits that are likely to respond to selection in such circumstances, we have no way of directly measuring the evoluti ....The Geometry of Genetic Limits to Evolutionary Change. Genetic limits to evolutionary change are a fundamental issue for plant and animal improvement, as well as understanding how natural populations may respond to human-induced changes such as habitat degradation and climate change. Because we still know very little about how genetic variation is distributed among the multiple traits that are likely to respond to selection in such circumstances, we have no way of directly measuring the evolutionary potential of any natural population. In this proposal, we develop the theory, statistical tools, and experimental designs to investigate the nature and prevalence of these multivariate genetic constraints.Read moreRead less

Our understanding of how selection in natural populations shape (favour and disfavour) immunity, and how this process contribute to organismal (including human) fitness, is rudimentary. In order to study such processes our collective experience strongly suggests and increasing need for geographic amalgamation of necessary and complementary molecular and biomedical techniques. We therefore request funding to establish a collaborative research laboratory in a novel research field - Evolutionary Immuno-Ecology- in which all vital aspects, from a mechanistic to an evolutionary level, can be studied at one research centre.Read moreRead less
