This project will provide answers to fundamental questions in evolutionary biology while identifying diet compositions that will benefit human health and well-being. Using a longitudinal public-health database, the Raine Study, and a theoretical framework from the field of Nutritional Ecology, the project will provide new knowledge on how nutrition affects key life-history traits in humans including immune function, reproductive health, physical appearance, and healthy ageing. A systematic literature review on how diet impacts these life-history traits in animals generally, and an experimental study of the effect of diet on health and reproduction in the house mouse (a lab analog species for humans) will complement the Raine Study findings.Read moreRead less
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

Green or crispy: Which plants use transpiration to survive heatwaves? Heatwaves are increasing in frequency and intensity, and extreme heat poses a significant threat to tree growth and survival. This project aims to investigate how different Australian tree species respond to extreme heat by tracking dynamic changes in water use during both natural and experimental heatwaves, representing current and future stress levels. Identification of a predictable response among plant functional types cou ....Green or crispy: Which plants use transpiration to survive heatwaves? Heatwaves are increasing in frequency and intensity, and extreme heat poses a significant threat to tree growth and survival. This project aims to investigate how different Australian tree species respond to extreme heat by tracking dynamic changes in water use during both natural and experimental heatwaves, representing current and future stress levels. Identification of a predictable response among plant functional types could be used to better forecast the potential effects of climate change on forest ecosystems. This project also expects to identify heat-tolerant tree species and their relevant physiological traits, which can improve the success of urban tree plantings to help create cooler, greener cities throughout Australia.Read moreRead less

Do novel diets reshape wildlife microbiomes and resilience to stressors? This project aims to investigate how bacteria can assist wildlife in adapting to the accelerating threat of environmental change. Using an innovative, interdisciplinary approach this project expects to identify interactions between environmental change and the diet, microbial communities and stress resilience of wildlife, using the threatened Grey-headed flying fox as a model system. Expected outcomes include detailed under ....Do novel diets reshape wildlife microbiomes and resilience to stressors? This project aims to investigate how bacteria can assist wildlife in adapting to the accelerating threat of environmental change. Using an innovative, interdisciplinary approach this project expects to identify interactions between environmental change and the diet, microbial communities and stress resilience of wildlife, using the threatened Grey-headed flying fox as a model system. Expected outcomes include detailed understanding of the role of microbial communities in shaping wildlife adaptations and development of ecological interventions to enhance wildlife resilience in Australia and globally. Such outcomes may reveal opportunities for management strategies that safeguard threatened species and reduce human-wildlife conflicts.Read moreRead less
Identifying how a non-stationary environment affects species persistence. This project aims to achieve the first application of new ecological theory that accounts for environmental change and species’ ability to respond to that change, using caddisflies that lay eggs on rocks in rivers as a case study. Long-term change in climate has always occurred but is often not accounted for when estimating future population sizes and extinction risk in species. Outcomes will include new knowledge on chang ....Identifying how a non-stationary environment affects species persistence. This project aims to achieve the first application of new ecological theory that accounts for environmental change and species’ ability to respond to that change, using caddisflies that lay eggs on rocks in rivers as a case study. Long-term change in climate has always occurred but is often not accounted for when estimating future population sizes and extinction risk in species. Outcomes will include new knowledge on changing habitat availability, species’ ability to move in the landscape and successfully lay and hatch eggs, while creating a general template for use in other species. This will lead to significant benefits for conservation efforts worldwide, via the template’s inclusion in accepted extinction assessment protocols.Read moreRead less
Can animal dispersal inform fire management for species conservation? This project aims to improve fire management for environmental outcomes in northern Australia. It will address a key knowledge gap in our understanding of the effects of fire on biodiversity, relating to the spatial pattern of fire in the landscape. This is important because changing patterns of fire are not only a risk to humans but have major effects on our environment. This project will involve researchers, environmental ma ....Can animal dispersal inform fire management for species conservation? This project aims to improve fire management for environmental outcomes in northern Australia. It will address a key knowledge gap in our understanding of the effects of fire on biodiversity, relating to the spatial pattern of fire in the landscape. This is important because changing patterns of fire are not only a risk to humans but have major effects on our environment. This project will involve researchers, environmental managers and indigenous land owners to design better fire management strategies for biodiversity. The key benefits include new knowledge and tools to better manage fire and address one of our major environmental challenges, the decline of native wildlife in northern Australia.Read moreRead less
Addressing social and ecological constraints to expand marine restoration. This project aims to improve social and ecological outcomes of marine habitat restoration by increasing community and industry engagement in restoration practices with high socio-economic benefits.

Understanding snow gum dieback for effective and integrated management. The project leverages recent research and infrastructure investments and our determined and collaborative team as it aims to: 1) assess the future geography of snow gum dieback in the high country and identify priority locations for pro-active management, 2) quantify the impact of snow gums on high country water and carbon budgets and thus the socio- economic and biodiversity values, and 3) determine options for mitigation. ....Understanding snow gum dieback for effective and integrated management.

Dieback of our iconic snow gum forests is diminishing the ecological, hydrological and cultural values of the Australian Alps and will impact state and national water-supply and power-generation systems. Our research will inform Alps-wide management efforts designed for long-term success.Read moreRead less
