A high throughput phenomics facility for pace of life traits in animals: This project seeks to create the first high-throughput phenomic facility for animals in Australia. The molecular revolution has brought unprecedented capacity to understand genetic variation. Genetic variation is now better understood and more easily and cheaply characterised than the physical traits that organisms exhibit. Linking phenotypic variation to genetic variation represents the major challenge in harnessing the power of the biomolecular age. This facility will accommodate animals from marine, freshwater and terrestrial systems across a diverse array of phyla. It will allow Australian researchers to leverage advances in high throughput genomic technologies to address a major bottleneck in biology.Read moreRead less

Summary
Evolution of chemical warfare in invasive plants. The project aims to test when, where and how exotic plant populations become invasive through the rapid evolution of chemical compounds that inhibit native plant species. Using an innovative quantitative genetics framework, the intended outcome is to determine how the chemicals are selected, and whether there is sufficient heritable variation for the chemicals to evolve across heterogeneous landscapes characteristic of introduced ranges. The proj ....Evolution of chemical warfare in invasive plants. The project aims to test when, where and how exotic plant populations become invasive through the rapid evolution of chemical compounds that inhibit native plant species. Using an innovative quantitative genetics framework, the intended outcome is to determine how the chemicals are selected, and whether there is sufficient heritable variation for the chemicals to evolve across heterogeneous landscapes characteristic of introduced ranges. The project will deliver key insights into the ecological and genetic mechanisms of adaptive evolution in invasive species, and predict evolutionary dynamics of biological invasions that inform their effective management. The project’s expected outcomes will be useful to policy makers, weed managers and farming communities.Read moreRead less
Comparative biosecurity informatics to anticipate invasive species threats. Invasive species cause billions in economic damages to Australia, but we do not have effective means to identify dangerous species before they arrive and cause harm. This project aims to overcome this challenge using the latest techniques in machine learning combined with genetic, ecological, and functional datasets for thousands of species. This project expects to generate a novel framework that allows us to identify an ....Comparative biosecurity informatics to anticipate invasive species threats. Invasive species cause billions in economic damages to Australia, but we do not have effective means to identify dangerous species before they arrive and cause harm. This project aims to overcome this challenge using the latest techniques in machine learning combined with genetic, ecological, and functional datasets for thousands of species. This project expects to generate a novel framework that allows us to identify and rank dangerous invasive species in an unbiased way, helping to safeguard Australia's unique biological community. Expected outcomes include improved methods for detecting ecologically and functionally similar species, providing substantial economic efficiency benefits to Australian biosecurity.Read moreRead less
The evolution of elaborate antennae in insects. This project will address several neglected but fundamental issues in the field of chemical communication and insect diversity. These include the evolutionary importance of receptor structures in a communication system, and the basis of diversity in one of the most defining characteristics of insects: antennae. The moth species in the proposed experiments are commercial pests of crops and therefore understanding of the evolutionary processes shapin ....The evolution of elaborate antennae in insects. This project will address several neglected but fundamental issues in the field of chemical communication and insect diversity. These include the evolutionary importance of receptor structures in a communication system, and the basis of diversity in one of the most defining characteristics of insects: antennae. The moth species in the proposed experiments are commercial pests of crops and therefore understanding of the evolutionary processes shaping their communication systems and mating behaviour will contribute to better predictive knowledge of the effects of control measures used against them. The project will also involve international collaboration to learn and develop new a technique in the analysis of pheromone communication. Read moreRead less

The primary impact will be to ensure that Australia maintains its high research profile in this field, and by contributing to research training through supervising and mentoring research students. Finally, our research will contribute to our understanding of the 'success' of major trans-global ant pest species, information that could prove useful in management strategies.Read moreRead less
Eco-evolutionary drivers of niche dynamics in invasive weeds. The project aims to understand how and why invasive species become invasive. Many exotic species are known to expand their ecological niches in their novel range, exploiting habitats that ancestral populations never used. Using a unique approach that combines field transplant and quantitative genetics experiments, this study will identify the drivers of niche expansion in invasive Australian capeweed, and predict if the invasive popul ....Eco-evolutionary drivers of niche dynamics in invasive weeds. The project aims to understand how and why invasive species become invasive. Many exotic species are known to expand their ecological niches in their novel range, exploiting habitats that ancestral populations never used. Using a unique approach that combines field transplant and quantitative genetics experiments, this study will identify the drivers of niche expansion in invasive Australian capeweed, and predict if the invasive populations are likely to further expand their niches. By delivering key insights into mechanisms of adaptive evolution in invasive species, this research should benefit efforts to effectively limit the spread of invasive plants that threaten the native environment.

How a ubiquitous endosymbiont of insects protects against pathogens. The project intends to determine the mechanism that underpins pathogen protection in insects. Insects harbour microbial communities in their cells and guts and confer a range of benefits on their hosts. One bacterium, Wolbachia, protects insects against co-infecting pathogens. The release of Wolbachia into mosquito populations is currently being tested as a means to reduce dengue virus transmission to humans.

Insects harbour microbial communities in their cells and guts and confer a range of benefits on their hosts. One bacterium, Wolbachia, protects insects against co-infecting pathogens. The release of Wolbachia into mosquito populations is currently being tested as a means to reduce dengue virus transmission to humans. Using innovative evolutionary and genetic approaches, the project proposes to elucidate the mechanism of pathogen blocking and ascertain its broader consequences for the host. This knowledge may be critical for maintaining the effectiveness of the biocontrol approach in the field by informing the development of resistance management strategies.Read moreRead less
The evolution of dispersal on range edges. The rate at which an invasive species spreads, and the ability of a native species to adapt to environmental change, are both contingent on the dispersal ability of the species. Dispersal ability, however, evolves rapidly on the edge of a species' range. The rapid evolution of dispersal, therefore, determines the eventual range-limits of invasive species, as well as of native species responding to changing conditions. This research will provide tools ....The evolution of dispersal on range edges.

Dispersal ability, however, evolves rapidly on the edge of a species' range. The rapid evolution of dispersal, therefore, determines the eventual range-limits of invasive species, as well as of native species responding to changing conditions. This research will provide tools with which to predict the direction and rate of dispersal evolution on range-edges. The results of this work will, thus, massively facilitate management of invasive species and climate change.Read moreRead less
Targeted gene flow for conservation. This project aims to develop targeted gene flow as a broad conservation strategy, exploiting natural geographic variation to achieve conservation outcomes. Geographic variation and local adaptation are ubiquitous within species, but conservation managers do not use this heritable variation. The project will develop decision tools to address when to time a targeted gene flow action, and where to source appropriate genetic variation. As case studies, the projec ....Targeted gene flow for conservation. This project aims to develop targeted gene flow as a broad conservation strategy, exploiting natural geographic variation to achieve conservation outcomes. Geographic variation and local adaptation are ubiquitous within species, but conservation managers do not use this heritable variation. The project will develop decision tools to address when to time a targeted gene flow action, and where to source appropriate genetic variation. As case studies, the project will try to use targeted gene flow to halt the invasion of the cane toad in northern Australia and reverse the decline of northern quolls.Read moreRead less
Evolution on the edge: a model system for evolution on invasion fronts. This project aims to develop a shared experimental platform, using the well-studied ecological model, Daphnia, to test emergent predictions about evolution on invasion fronts. Evolution happens rapidly on invasion fronts, accelerating the speed and potentially the damage caused by an invasion. By manipulating invasions through an experimental landscape, the project aims to answer currently infeasible questions, including whe ....Evolution on the edge: a model system for evolution on invasion fronts. This project aims to develop a shared experimental platform, using the well-studied ecological model, Daphnia, to test emergent predictions about evolution on invasion fronts. Evolution happens rapidly on invasion fronts, accelerating the speed and potentially the damage caused by an invasion. By manipulating invasions through an experimental landscape, the project aims to answer currently infeasible questions, including whether pathogens become more virulent as they spread, and whether evolutionary trade-offs place limits on spread rate. This work would dramatically improve our understanding of biological invasions and may have implications for the management of phenomena ranging from emergent diseases to invasive pests and malignant growths.Read moreRead less
