Linking individual traits, the gut microbiome and parasite load in wildlife. This project aims to apply principles of community ecology to the gut microbiome of an urban exploiter – the common brushtail possum - to reveal how animal traits influence individual variation in the load of gut parasites that cause disease in both humans and wildlife. By combining assays defining the behavioural and physiological states of individuals with sophisticated analyses of their gut microbiome, our project wi ....Linking individual traits, the gut microbiome and parasite load in wildlife. This project aims to apply principles of community ecology to the gut microbiome of an urban exploiter – the common brushtail possum - to reveal how animal traits influence individual variation in the load of gut parasites that cause disease in both humans and wildlife. By combining assays defining the behavioural and physiological states of individuals with sophisticated analyses of their gut microbiome, our project will provide a new, yet crucial, perspective on how and why diseases spread. Our discoveries will help understand and manage the burden of infectious diseases from parasites in and beyond our cities and across the human-wildlife interface; essential for improving human and wildlife health in an increasingly urbanised Australia.Read moreRead less
Genetic rescue of Australian wildlife. Genetic rescue of Australian wildlife. This project aims to test genetic rescue as an efficient recovery technique for threatened plants and animals. Genetic rescue is under-utilised, even though it is overwhelmingly beneficial.

Global change is driving thousands of species towards extinction. Legislation requires the protection of biodiversity, but current scientific understanding of species declines limits effective action. By taking a new approach to studying species declines, this integrative research aims to identify why some species persist, while others decline. This project is expected to improve understanding of species vulnerability to extinction, and the conditions which allow species to coexist with threats. Anticipated benefits include advancing ecological theory, improving conservation planning, and increasing the efficiency and effectiveness of policy and management to prevent species extinctions.Read moreRead less
Using pollinators to optimise plant conservation translocation. This project aims to address the low success rate of conservation translocations of threatened orchids. While pollinators are critical for plant reproduction, they are very rarely considered when establishing new populations of endangered species. Our innovative approach to conservation translocation involves using pollinators in site selection, developing strategies to mitigate risks of hybridisation, and optimising plant reproduct ....Using pollinators to optimise plant conservation translocation. This project aims to address the low success rate of conservation translocations of threatened orchids. While pollinators are critical for plant reproduction, they are very rarely considered when establishing new populations of endangered species. Our innovative approach to conservation translocation involves using pollinators in site selection, developing strategies to mitigate risks of hybridisation, and optimising plant reproduction through planting design. The key outcome will be best-practice protocols to fast-track the establishment of self-sustaining populations. Due to their novelty, the approaches we develop will benefit plant translocations worldwide, and lead to enhanced conservation outcomes at reduced financial cost. Read moreRead less
Diatom lipids to reveal sea-ice history in remote Antarctic regions. This project aims to understand seasonal Antarctic sea-ice extent using molecular, geochemical, elemental and genomic characteristics of specific marine phytoplankton (diatoms). Little is known of the seasonal sea-ice variation and the position of the summer sea-ice extent a million years before satellite records, but this information is critical to determining air-sea gas exchange and ecosystem food web regulation. This projec ....Diatom lipids to reveal sea-ice history in remote Antarctic regions. This project aims to understand seasonal Antarctic sea-ice extent using molecular, geochemical, elemental and genomic characteristics of specific marine phytoplankton (diatoms). Little is known of the seasonal sea-ice variation and the position of the summer sea-ice extent a million years before satellite records, but this information is critical to determining air-sea gas exchange and ecosystem food web regulation. This project will unite geochemical and biological approaches to provide the data to improve past Antarctic ecosystem and climate models where sea-ice data is missing. Studying diatom biomarkers in deep sea cores from Australia’s Southern Ocean will redefine knowledge of Antarctic climate and provide data necessary to improve global ecosystem and climate models.Read moreRead less

This project aims to develop a global approach to synthesise global tracking datasets and deliver near real-time diagnostics on risks for marine megafauna at a global scale pushing forward a new frontier in dynamic marine spatial management to improve conservation. This project expects to increase our understanding of how marine megafauna movements vary with environmental changes and how much they overlap with threatening global human activities. Expected outcomes will demonstrate how big data in marine telemetry can be synthesised and translated into ecologically significant behaviours. This should provide significant benefits to address global scientific and societal problems highlighted in the Australian science and research priorities.Read moreRead less

Summary
The role of enemies in the generation of biodiversity. A fundamental question in biology is how new species are generated. The role of abiotic factors has been widely explored, but there is still little known about the role that ecological or behavioural interactions between organisms, such as parasitism or predation, play in the generation of diversity. This project aims to test the importance of anti-predator defences (warning colours) in generating species.

The role of abiotic factors has been widely explored, but there is still little known about the role that ecological or behavioural interactions between organisms, such as parasitism or predation, play in the generation of diversity. This project aims to test the importance of anti-predator defences (warning colours) in generating species. It will combine micro- and macroevolutionary analyses to provide an in-depth test of this association. This project aims to provide a bridge between behavioural ecology and macroevolutionary processes, using Australian fauna, and increase our knowledge about whether and how enemies can contribute to generating diversity of life on earth.Read moreRead less
