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

Minimum sizes and habitat areas for viable populations. This project will address two critical issues in conservation biology: How large do wildlife populations need to be to ensure long-term persistence? How large an area needs to be preserved? At present, no such estimates exist for most species. I will develop realistic population viability analysis (PVA) models (encompassing all threats to persistence) on many bird, mammal, reptile, amphibian, invertebrate and plant species, and estimate the ....Minimum sizes and habitat areas for viable populations. This project will address two critical issues in conservation biology: How large do wildlife populations need to be to ensure long-term persistence? How large an area needs to be preserved? At present, no such estimates exist for most species. I will develop realistic population viability analysis (PVA) models (encompassing all threats to persistence) on many bird, mammal, reptile, amphibian, invertebrate and plant species, and estimate the minimum population sizes and habitat areas required for long-term survival. My prior research has validated the predictive accuracy of PVA. This research will deliver practical guidelines for managing threatened species.Read moreRead less
Traditional knowledge and intellectual property: A comparison of current approaches in Australia, Indonesia and the Philippines. The concepts of 'indigenous cultural and intellectual property rights' and 'traditional resource rights' have sparked a debate between resource-rich developing countries and technology rich industrialised nations, because of their importance for biotechnology and pharmaceutical research. This comparative study combines legal analysis and fieldwork to critically examine ....Traditional knowledge and intellectual property: A comparison of current approaches in Australia, Indonesia and the Philippines. The concepts of 'indigenous cultural and intellectual property rights' and 'traditional resource rights' have sparked a debate between resource-rich developing countries and technology rich industrialised nations, because of their importance for biotechnology and pharmaceutical research. This comparative study combines legal analysis and fieldwork to critically examine cultural assumptions about the relationship of indigenous communities to their symbols and their environment. The examination will extend to Southeast Asia to discover different concepts of 'indigenous' and different mechanisms for the interaction between state and customary law. Asian experiences with legislation in this field will provide useful insights for legislators in Australia.Read moreRead less
Heat stress in the workplace: health burden and labour productivity loss. This project aims to estimate the economic loss of workplace heat exposure in Australia. The project will investigate the health services costs of occupational heat-related illnesses/injuries, explore the labour productivity loss and its costs resulting from heat stress at work, and estimate the benefits from a generic heat warning intervention for workplace heat prevention. Outcomes are expected to provide an overview of ....Heat stress in the workplace: health burden and labour productivity loss. This project aims to estimate the economic loss of workplace heat exposure in Australia. The project will investigate the health services costs of occupational heat-related illnesses/injuries, explore the labour productivity loss and its costs resulting from heat stress at work, and estimate the benefits from a generic heat warning intervention for workplace heat prevention. Outcomes are expected to provide an overview of national economic implications at present and in the future from effective heat stress control, assist the development of work place heat policies, and inform resource allocation to make Australian workplaces well prepared for likely increasing extremely hot weather.Read moreRead less

Expected benefits of this project are greater intergenerational transfer of Indigenous biocultural knowledge through working on country and enhanced Indigenous capacity. Read moreRead less
Do frogs hydroregulate? Regulation versus tolerance of thermal and hydric states. Amphibians are in decline in Australia and worldwide. Frogs are a middle link in terrestrial and aquatic food chains (as predators and prey) so are important for the sustainability of Australia's biodiversity and as indicators of environmental problems. Basic research about the ways Australian frogs interact with the physical environment to balance body water and temperature is crucial to predicting the effects of ....Do frogs hydroregulate? Regulation versus tolerance of thermal and hydric states. Amphibians are in decline in Australia and worldwide. Frogs are a middle link in terrestrial and aquatic food chains (as predators and prey) so are important for the sustainability of Australia's biodiversity and as indicators of environmental problems. Basic research about the ways Australian frogs interact with the physical environment to balance body water and temperature is crucial to predicting the effects of climate change or habitat modification on frogs. This basic information is needed to produce effective conservation plans for native frogs and management plans for invasive cane toads. We will train students in techniques and concepts in ecology, conservation biology, and animal physiology.Read moreRead less
The ecological impact of large carnivore restoration. This project aims to assess the ecological changes that have arisen due to the repatriation of estuarine crocodiles to Australian ecosystems.

This project aims to assess the ecological changes that have arisen due to the repatriation of estuarine crocodiles to Australian ecosystems. It is significant because the restoration provides a rare opportunity to empirically test changes in ecosystem processes under varying degrees of large carnivore predation pressure. Expected outcomes include improved understanding of the processes that govern the strength of predator-ecosystem interactions and an ability to quantify the biomass, social structure, and behaviours of predators required to influence these processes. Benefits should include improvements in how the ecological role of large carnivores is measured, and when and where carnivore populations should be culled or conserved.Read moreRead less
