The project aims to create a quantitative modelling framework for assessing the absolute sustainability of cities by combining global multi-region input-output analysis with the 'safe and just space' concept for human development. The model will allow assessment of the full supply chain environmental and social impacts of urban economic activities against biophysical planetary limits as well as social foundation thresholds defined in the literature. The project will advance sustainability science methodology and will greatly benefit worldwide initiatives for urban sustainability. Case studies on Australian cities will assess where interventions can be most practically, realistically and effectively implemented.Read moreRead less
Optimal environmental monitoring under severe uncertainty. Environmental monitoring is a type of quality control that informs managers about the health of the environment and about how well their management systems are performing. Because it is a critical, but expensive, component of sustainable management, it is important to ensure value for resources spent on monitoring and that environmental impacts will be detected if they are occurring. We argue that current approaches to environmental mana ....Optimal environmental monitoring under severe uncertainty. Environmental monitoring is a type of quality control that informs managers about the health of the environment and about how well their management systems are performing. Because it is a critical, but expensive, component of sustainable management, it is important to ensure value for resources spent on monitoring and that environmental impacts will be detected if they are occurring. We argue that current approaches to environmental management ensure neither efficiency nor environmental security. The aim of the project is to develop theories and techniques to make monitoring both cost effective and reliable, thereby providing monetary savings and better environmental outcomes.Read moreRead less
Exposure mapping - combining wastewater analysis with human biomonitoring. This project aims to develop a spatial and temporal understanding of chemical exposure in the Australian population. The project will use wastewater samples collected from over 100 catchments (65% of Australian population) during the 2016 Census to spatially resolve human exposure to chemicals. These data will then form the basis for focused human biomonitoring using pooled surplus pathology samples. The integration of ....Exposure mapping - combining wastewater analysis with human biomonitoring. This project aims to develop a spatial and temporal understanding of chemical exposure in the Australian population. The project will use wastewater samples collected from over 100 catchments (65% of Australian population) during the 2016 Census to spatially resolve human exposure to chemicals. These data will then form the basis for focused human biomonitoring using pooled surplus pathology samples. The integration of wastewater and biomonitoring data will allow the creation of a national hazard specific exposure map that can be compared with geospatial data on disease risk and socioeconomic indicators (via ABS information). The benefits include the capability to identify and manage exposure risks to public health.Read moreRead less
Microplastic infiltration of food webs: cells to ecosystem consequences. Using trophic ecological theory as a framework, this project aims to provide the first comprehensive assessment of the fate and effects of microplastics. Plastic pollution is a persistent and increasing problem. Plastics are degraded into small particles, called microplastics, which are ingested by animals. The project aims to develop much-needed techniques to measure microplastics in biological tissue and apply these techn ....Microplastic infiltration of food webs: cells to ecosystem consequences. Using trophic ecological theory as a framework, this project aims to provide the first comprehensive assessment of the fate and effects of microplastics. Plastic pollution is a persistent and increasing problem. Plastics are degraded into small particles, called microplastics, which are ingested by animals. The project aims to develop much-needed techniques to measure microplastics in biological tissue and apply these techniques in food web studies to determine the capacity of microplastics to transfer from the environment into animals, and how microplastics move through a food web to affect biological diversity and animal health. This information will be used to complete the first risk assessment for microplastics in a major coastal habitat.Read moreRead less
Contemporary sulfur biomineralisation in acid sulfate soil landscapes. This project aims to generate fundamental knowledge on the processes, kinetics and impacts to water quality of contemporary sulfur biomineralisation in acid sulfate soil landscapes. Extreme concentrations of highly reactive sulfides are forming in the surface sediments of floodplain drains, wetlands and agricultural soils. The newly forming sulfides are linked to severe oxygen depletion and acidification of coastal rivers a ....Contemporary sulfur biomineralisation in acid sulfate soil landscapes. This project aims to generate fundamental knowledge on the processes, kinetics and impacts to water quality of contemporary sulfur biomineralisation in acid sulfate soil landscapes. Extreme concentrations of highly reactive sulfides are forming in the surface sediments of floodplain drains, wetlands and agricultural soils. The newly forming sulfides are linked to severe oxygen depletion and acidification of coastal rivers and the complete failure of floodplain vegetation, leaving soils susceptible to erosion. The proposed study will greatly advance our understanding of how our precious coastal floodplain soil and water resources are being degraded, and will guide better land management.

Using species distribution models to make robust conservation decisions. Species distribution models inform numerous conservation decisions, from planning reserves and managing biological invasions to assessing climate change impacts. While it is often vital to predict where suitable conditions for a species occur, many applications disregard uncertainty, leading to unexpected and potentially unacceptable outcomes. This project aims to provide a definitive guide to using species distribution mod ....Using species distribution models to make robust conservation decisions. Species distribution models inform numerous conservation decisions, from planning reserves and managing biological invasions to assessing climate change impacts. While it is often vital to predict where suitable conditions for a species occur, many applications disregard uncertainty, leading to unexpected and potentially unacceptable outcomes. This project aims to provide a definitive guide to using species distribution models in conservation decision-making by integrating ecological and statistical thinking with decision theory. It seeks to describe how to explore the sources of uncertainty and their impact, develop approaches to reducing uncertainty, and evaluate the effects of uncertainty from the decision viewpoint in order to assist more robust conservation decision making.Read moreRead less

This research will make significant contributions to planning for An Environmentally Sustainable Australia. Key outcomes will include guidelines for including, for the first time, the patch dynamics of coral bleaching and pelagic productivity in conservation planning. By using an Australian icon, the Great Barrier Reef, as the case study for this research, the findings will be directly applicable and implementable. Furthermore, this study will result in an understanding of the potential effect of climate change on patch dynamics, and will provide guidelines and theory for planning for such changes. This research will enable Australia to effectively protect its biodiversity and to relate this knowledge to its neighbours.Read moreRead less
The pharmacokinetics of plant secondary metabolites and their effects on feeding in the brushtail possum. Plant secondary metabolites (PSMs) are considered to protect against herbivory, although the mechanisms are not well understood. This project will determine how marsupial folivores avoid toxicity when browsing on Eucalyptus leaf. Blood levels of terpenes, phenols and their metabolites will be measured in the brushtail possum while it feeds on a diet of varying PSM content. We expect to be ab ....The pharmacokinetics of plant secondary metabolites and their effects on feeding in the brushtail possum. Plant secondary metabolites (PSMs) are considered to protect against herbivory, although the mechanisms are not well understood. This project will determine how marsupial folivores avoid toxicity when browsing on Eucalyptus leaf. Blood levels of terpenes, phenols and their metabolites will be measured in the brushtail possum while it feeds on a diet of varying PSM content. We expect to be able to show relationships between the ingestion and blood levels of PSMs and feeding behaviour. This will give a greater understanding of the effect of plant toxins on browsing behaviour, enabling improved foraging models and more effective habitat management.Read moreRead less
Unravelling community interactions between mammals and fungi, and the role of mycophagy in mediating biodiversity and driving ecosystem processes. Maintenance of Australia's forest biodiversity and healthy forested ecosystems are of national importance. Mammal species that are key to dispersing beneficial fungi in our forests have suffered greatest declines in the past, and further declines may ultimately lead to ecosystem collapse.

Maintenance of Australia's forest biodiversity and healthy forested ecosystems are of national importance. Mammal species that are key to dispersing beneficial fungi in our forests have suffered greatest declines in the past, and further declines may ultimately lead to ecosystem collapse. My research seeks to unravel community relationship between mammals and fungi, and how interactions within and between these groups maintain diverse communities. My results will enable forest managers to protect forest biodiversity from current and future threats and to restore degraded ecosystems. Through training of early career ecologists, the research also represents a tangible benefit to Australian science.Read moreRead less
Enhancing and evaluating stakeholder engagement for improved water outcomes. Stakeholder engagement, widely recognised as essential in successful water governance, remains ad hoc both in practice and as a research theme. Using a detailed analysis of a complex evolutionary case of stakeholder engagement in water management in the Murray-Darling Basin (1900- 2020), this project aims to develop new approaches to measure the structure and form of socio-culturally derived stakeholder engagement syste ....Enhancing and evaluating stakeholder engagement for improved water outcomes. Stakeholder engagement, widely recognised as essential in successful water governance, remains ad hoc both in practice and as a research theme. Using a detailed analysis of a complex evolutionary case of stakeholder engagement in water management in the Murray-Darling Basin (1900- 2020), this project aims to develop new approaches to measure the structure and form of socio-culturally derived stakeholder engagement system, to improve socio-economic and environmental benefits from water. The expected output is a new diagnostic tool for evaluating stakeholder engagement that can be taken up by governing bodies. The expected benefit is more inclusive, equal, and adaptive water governance through more effective stakeholder engagement.Read moreRead less
