Tracking the molecular dynamics of adaptation with horizontal gene transfer. This project aims to track the dynamics of adaptation with gene exchange by building the first experimental evolution model that can directly observe this process. The acquisition of genes from other strains and species (horizontal gene transfer) frequently underlies bacterial adaptation, but it is unknown how this occurs. This project aims to shift understanding of how microbial populations respond to environmental cha ....Tracking the molecular dynamics of adaptation with horizontal gene transfer. This project aims to track the dynamics of adaptation with gene exchange by building the first experimental evolution model that can directly observe this process. The acquisition of genes from other strains and species (horizontal gene transfer) frequently underlies bacterial adaptation, but it is unknown how this occurs. This project aims to shift understanding of how microbial populations respond to environmental challenges. There are significant benefits to be gained from understanding how microbes adapt in response to climate change and the widespread application of antibiotics, given that microbial populations form intimate associations with humans and sustain all of the world’s ecosystems.Read moreRead less
Understanding climate and harvest induced changes in fish life histories. This project aims to quantify the cumulative impacts of harvest and climate change across marine fishes and ecosystems. The project expects to generate new knowledge in this area by coupling the rich biological information archived in fish ear bones, with targeted multi-generation experiments and predictive modelling.

This project aims to quantify the cumulative impacts of harvest and climate change across marine fishes and ecosystems. The project expects to generate new knowledge in this area by coupling the rich biological information archived in fish ear bones, with targeted multi-generation experiments and predictive modelling. Expected outcomes include fundamental insights into how human-induced environmental change affects fish growth and maturation, and a subsequent critical evaluation of the sensitivity of fisheries models to trends in these life-history traits. This should provide significant benefits to fisheries and ecosystem management, ensuring they remain productive and resilient in a time of rapid environmental change.Read moreRead less

Summary
Confocal microscope for high-resolution microtopographic analysis of surfaces in historical, forensic and polymer sciences. High-resolution analyses of microscopic patterns on surfaces using confocal microscopy can provide vital clues into the nature of ancient diets and environments, adaptive evolution, weapons used in crimes, and properties of polymers. This instrument will heighten Australia’s capacity for world-leading research in areas of major national importance.
Experimental co-evolution of Yeast and E. coli. This project aims to measure the rates and genetic mechanisms of adaptation for individual species within a microbial community. Expected outcomes of this interdisciplinary project include the first genomic and phenotypic dataset of a model microbial community, and novel tools for the analysis of meta-genomic datasets. This project has the potential to transform understanding of microbial adaptation.
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.

Predicting adaptive responses to climate change in Australian native bees. This project aims to understand how insects will adapt to climate change by examining a largely overlooked but economically important group of species: Australian native bees. Native bees are important pollinators of both crops and native plants, but their sensitivity to changes in climate are unknown. Expected outcomes include new knowledge of the resilience of native bees to climate change, and new effective tools for p ....Predicting adaptive responses to climate change in Australian native bees. This project aims to understand how insects will adapt to climate change by examining a largely overlooked but economically important group of species: Australian native bees. Native bees are important pollinators of both crops and native plants, but their sensitivity to changes in climate are unknown. Expected outcomes include new knowledge of the resilience of native bees to climate change, and new effective tools for predicting climate change resilience that can be applied to many species. The intended benefits include increasing our understanding of the potential for native bees to act as future pollinators in Australia’s natural and agro-ecosystems, and guide policy and management decisions to better protect and conserve our bee fauna.Read moreRead less
Interacting with change: inter-specific competition and climate change . The project aims to understand how species will adapt to climate change by examining a largely overlooked process: how competition shapes evolutionary responses. Rising temperatures will fundamentally alter where species live, re-shuffling communities. Yet, how changes in community composition will affect the way current assessments of species vulnerability to climate change is generally unknown. Expected outcomes include i ....Interacting with change: inter-specific competition and climate change . The project aims to understand how species will adapt to climate change by examining a largely overlooked process: how competition shapes evolutionary responses. Rising temperatures will fundamentally alter where species live, re-shuffling communities. Yet, how changes in community composition will affect the way current assessments of species vulnerability to climate change is generally unknown. Expected outcomes include improved species models for predicting responses to climate change through the integration of competitive effects with environmental data. The benefit will be an increased accuracy in predictions of species at risk to climate change which will guide policy and management decisions to protect vulnerable environments better.Read moreRead less
Computing the climate-life history nexus for Australia's fauna. Life histories are the trajectories organisms follow as they develop, grow, reproduce and age; they are shaped by evolution and limited by the physical and biological environment. Recent breakthroughs by the CI allow the computation of life histories in any sequence of climatic environments, with demonstrated potential to gain new insights into the past, present and future responses of species to climate variability and change.

Recent breakthroughs by the CI allow the computation of life histories in any sequence of climatic environments, with demonstrated potential to gain new insights into the past, present and future responses of species to climate variability and change. This project aims to apply the new methods to understand how species' life histories have adapted to Australia's unique physical conditions and predict how they will respond to future conditions. It will simultaneously lay the foundations for a long-term, open-access research program on species' climate responses.Read moreRead less

Evolution in tooth and claw: exploring the relationship between the radiation of marsupial herbivores and late Cenozoic climate change. Establishing how animals responded to past environmental changes is essential for understanding the ecology of modern species and managing them in light of contemporary climatic trends. By applying several novel analytical methods this project will unravel the links between the radiation of Australian marsupials and key stages in climatic evolution.
