Skin Microbes and Animal Health: Understanding the Ecological Context. This project aims to understand the fundamental ecological relationships between animal hosts (frogs, geckos) and bacteria on their skin by separating host effects from environmental factors that determine skin microbiome composition. The research is significant because it will generate new knowledge needed to understand how skin microbes function in providing protection against disease. Expected outcomes include the provisio ....Skin Microbes and Animal Health: Understanding the Ecological Context. This project aims to understand the fundamental ecological relationships between animal hosts (frogs, geckos) and bacteria on their skin by separating host effects from environmental factors that determine skin microbiome composition. The research is significant because it will generate new knowledge needed to understand how skin microbes function in providing protection against disease. Expected outcomes include the provision of essential information that will guide future research efforts on the factors that determine a healthy skin microbial community (which is needed before skin diseases can be combated). The research will provide significant benefits, including more targeted conservation efforts to combat wildlife skin diseases.Read moreRead less
Next generation high throughput lipidomics using adaptive modelling. This project aims to develop a unique high-throughput method to capture the lipidomic profile of human plasma suitable for large human population screening. Lipids are fundamental to every biological system, but our understanding of their regulation in humans have been largely superficial. By incorporating a new lipidomics approach, with genomic data, this project aims to expand our understanding of human biology by identifying ....Next generation high throughput lipidomics using adaptive modelling. This project aims to develop a unique high-throughput method to capture the lipidomic profile of human plasma suitable for large human population screening. Lipids are fundamental to every biological system, but our understanding of their regulation in humans have been largely superficial. By incorporating a new lipidomics approach, with genomic data, this project aims to expand our understanding of human biology by identifying regulators of lipid metabolism. The large diversity in humans necessitate sufficient sample sizes to identify true genetic regulators, but to date techniques capturing phenotypic data (lipids) have been largely limited. It is anticipated that this study will identify new regulators of lipid metabolism in humans.Read moreRead less
How does habitat complexity drive motor ageing and fitness in wild mammals? This project aims to demonstrate how habitat complexity shapes motor ageing in wild dasyurid marsupials, and to improve these animals’ motor function, slow its decline and increase reproductive output via behavioural and physiological changes. Motor decline should dramatically impact an animal growth, survival and reproduction by affecting how it moves through habitats when foraging, seeking mates, or escaping from preda ....How does habitat complexity drive motor ageing and fitness in wild mammals? This project aims to demonstrate how habitat complexity shapes motor ageing in wild dasyurid marsupials, and to improve these animals’ motor function, slow its decline and increase reproductive output via behavioural and physiological changes. Motor decline should dramatically impact an animal growth, survival and reproduction by affecting how it moves through habitats when foraging, seeking mates, or escaping from predators. However, little is known about the environmental drivers of motor ageing in wild animals. Our project addresses an important gap in the field of evolutionary ecology. Since decline in muscle function affects the quality of Australian's life, our work could lead to important economic and health implications.Read moreRead less
Do marine heat waves cause pathogen outbreaks in Australian coastal waters? This project aims to identify links between increasingly frequent Marine Heat Wave (MHW) events and outbreaks of microbes that cause disease in marine animals, reduced aquaculture yields and human health hazards. Pathogenic bacteria from the Vibrio genus exhibit a preference for elevated seawater temperature and this project will test the hypothesis that episodic MHWs will trigger blooms of dangerous species. Using innov ....Do marine heat waves cause pathogen outbreaks in Australian coastal waters? This project aims to identify links between increasingly frequent Marine Heat Wave (MHW) events and outbreaks of microbes that cause disease in marine animals, reduced aquaculture yields and human health hazards. Pathogenic bacteria from the Vibrio genus exhibit a preference for elevated seawater temperature and this project will test the hypothesis that episodic MHWs will trigger blooms of dangerous species. Using innovative ecogenomic tools, this project will track the impact of MHWs on the dynamics of pathogenic Vibrio within coastal habitats, oyster farming facilities and coral reefs. The benefit of this project will be essential new knowledge on an emerging threat to Australia’s valuable marine estate, food security and public health.Read moreRead less
Australian savannah landscapes: past, present and future. Australian savannahs are productive and culturally and biologically significant landscapes but are vulnerable to climate change. The project will determine savannah function (carbon and water balance) for the present and assess how sensitive they have been to past climate variability. The project will then address how they may respond to future climate change.
What is 'natural'?: Locating and deciphering pre-human records of vegetation from northern Australian savannahs. The nature and magnitude of the environmental impact of human colonisation of Australia are fundamental issues in Australian prehistory and ecology. The project will locate and develop archives of environmental change from sinkholes in the Northern Territory that date back to the Last interglacial - a period which had a similar climate to the present day, but was before humans arrived ....What is 'natural'?: Locating and deciphering pre-human records of vegetation from northern Australian savannahs.

Beyond burial: redefining the blue carbon paradigm. This project aims to constrain the magnitude and drivers of alkalinity and greenhouse gas fluxes in mangroves. Mangroves cover less than 0.03 per cent of the Earth’s surface yet account for approximately 14 per cent of oceanic carbon burial. Mangroves also export alkalinity to the coastal ocean, and act as sources of methane and nitrous oxide. The effect of these fluxes on climate may exceed carbon burial by several-fold, but are unaccounted fo ....Beyond burial: redefining the blue carbon paradigm. This project aims to constrain the magnitude and drivers of alkalinity and greenhouse gas fluxes in mangroves. Mangroves cover less than 0.03 per cent of the Earth’s surface yet account for approximately 14 per cent of oceanic carbon burial. Mangroves also export alkalinity to the coastal ocean, and act as sources of methane and nitrous oxide. The effect of these fluxes on climate may exceed carbon burial by several-fold, but are unaccounted for in blue carbon budgets. This project will couple high-resolution radionuclide geochronology of soil carbon cycling with autonomous measurements of aquatic exports and greenhouse gas fluxes. This study will provide the detailed data required to refine the blue carbon paradigm.Read moreRead less
