Summary
Genetic and epigenetic drivers of the Australian cane toad invasion. Although invasive species are a massive threat to biodiversity, and costly to society, we still do not understand the evolutionary processes that shape invasions. Invasive populations often show rapid evolutionary change in novel environments but attempts to identify the underlying genetic mechanisms have been largely unsuccessful. This project aims to explore an innovative and untested alternative possibility: that invader evo ....Genetic and epigenetic drivers of the Australian cane toad invasion. Although invasive species are a massive threat to biodiversity, and costly to society, we still do not understand the evolutionary processes that shape invasions. Invasive populations often show rapid evolutionary change in novel environments but attempts to identify the underlying genetic mechanisms have been largely unsuccessful. This project aims to explore an innovative and untested alternative possibility: that invader evolution is primarily driven by epigenetic change. Using an iconic Australian invasive species, the cane toad, the project aims to quantify genetic and epigenetic change across the invasion and use manipulative experiments to determine the influence of epigenetic change on the evolution of phenotypic traits important to invasion.Read moreRead less

Summary
New approaches for pest control and maintaining healthy environments under climate change. Natural environments are rapidly changing due to climate and human population pressure, affecting food supply and natural heritage. Insects and other invertebrates perform essential services like pollination, pest control and soil turnover, and provide food for wildlife. These services are under threat, and ways of maintaining them and protecting biodiversity need to be developed. This project will identif ....New approaches for pest control and maintaining healthy environments under climate change. Natural environments are rapidly changing due to climate and human population pressure, affecting food supply and natural heritage. Insects and other invertebrates perform essential services like pollination, pest control and soil turnover, and provide food for wildlife. These services are under threat, and ways of maintaining them and protecting biodiversity need to be developed. This project will identify the genetic and evolutionary mechanisms that insects use to deal with environmental changes and the processes that promote evolutionary resilience to safeguard environmental services. This should lead to guidelines for sustainable agricultural production and biodiversity protection in threatened environments like the Australian Alps.Read moreRead less
Evolution in action or the demise of iconic Australian flora? The project aims to investigate the evolutionary history and conservation status of a group of closely related Grevillea species, in the light of increasing pressure from landscape modification. This project will incorporate leading methodologies for massively parallel sequencing, pollinator preference and breeding capacity in order to detect the patterns and processes underpinning divergence in widely distributed species. A phylogene ....Evolution in action or the demise of iconic Australian flora? The project aims to investigate the evolutionary history and conservation status of a group of closely related Grevillea species, in the light of increasing pressure from landscape modification. This project will incorporate leading methodologies for massively parallel sequencing, pollinator preference and breeding capacity in order to detect the patterns and processes underpinning divergence in widely distributed species. A phylogenetic framework will provide the evolutionary relationships among taxa. This project is expected to inform requirements for long-term species persistence and, for threatened species within the group, guide the decision making of biodiversity managers as to what actions are required and where best to invest limited funds.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
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. 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 an ....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. 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
Revealing the evolutionary and ecological dynamics of avian influenza virus. This project aims to understand how avian influenza virus (AIV) emerges, evolves and spreads in wild birds. AIV has the potential to devastate the poultry industry and cause human pandemics, but the factors that shape the genetic diversity of AIV in its wild bird reservoir are poorly understood. The project plans to combine genomic, ecological and phylogenetic approaches to reveal key aspects of AIV evolution, as well a ....Revealing the evolutionary and ecological dynamics of avian influenza virus. This project aims to understand how avian influenza virus (AIV) emerges, evolves and spreads in wild birds. AIV has the potential to devastate the poultry industry and cause human pandemics, but the factors that shape the genetic diversity of AIV in its wild bird reservoir are poorly understood. The project plans to combine genomic, ecological and phylogenetic approaches to reveal key aspects of AIV evolution, as well as the risk for future viral emergence. Using sampling sites in Australia and Antarctica, it plans to investigate AIV diversity, the evolutionary dynamics of AIV in wild birds and poultry, and the role played by environmental transmission in AIV ecology.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
Predicting adaptation and range expansion under climate change. This project investigates the repeatability and thereby the predictability of adaptation to climate change by leveraging 1000 genomes sampled over 150 years and multiple climatic gradients in the rapidly adapting, globally invasive, and highly allergenic ragweed. We expect to deepen our understanding of the genetic basis of adaptation and decipher the circumstances under which adaptive genetic change is repeatable, by integrating a ....Predicting adaptation and range expansion under climate change. This project investigates the repeatability and thereby the predictability of adaptation to climate change by leveraging 1000 genomes sampled over 150 years and multiple climatic gradients in the rapidly adapting, globally invasive, and highly allergenic ragweed. We expect to deepen our understanding of the genetic basis of adaptation and decipher the circumstances under which adaptive genetic change is repeatable, by integrating a novel evolutionary model with genomic data. We will develop the capacity to predict species’ distributions and trait evolution under climate change using a powerful empirical dataset. This will provide us with the capacity to anticipate and manage the effects of climate change on noxious and threatened species.Read moreRead less
Testing evolutionary predictions about multiple unrelated traits under changed environmental conditions using visual ecology. An understanding of evolution is vital in managing the effects of environmental change. Senses determine success in survival/reproduction and environmental change affects what is sensed. This project will make and test explicit predictions about evolution under changed conditions using visual physiology, environmental parameters and evolution experiments.
