It also provides a common platform for government agencies, from Department of Environment and Heritage to the Federal Police, and will create new tools to improve water management, biosecurity, forensics/policing and human health, as reflected by the wide range of industry partners supporting the project.Read moreRead less
Addressing the uncertainties: Pathways, fate and associated risks of manufactured nanoparticles in the environment. Manufactured nanomaterials are increasingly present in commercial products, such as sunscreens, textiles and building materials. Their subsequent release to the environment is unavoidable. This project will deliver novel methods for assessing the associated risks, thereby supporting the safe and sustainable use of nanomaterials in Australia.
Is mass commercialisation of silver-based nanotechnology undermining its biomedical antibacterial potential? Silver nanoparticles have demonstrated broad spectrum antibacterial potential and are increasingly used in biomedical applications to limit infection. They are also found in a growing range of everyday products such as shampoos and socks. This situation is analogous to the previous use of antibiotics for nonmedical purposes and the subsequent spread of antibiotic resistant bacteria. This ....Is mass commercialisation of silver-based nanotechnology undermining its biomedical antibacterial potential? Silver nanoparticles have demonstrated broad spectrum antibacterial potential and are increasingly used in biomedical applications to limit infection. They are also found in a growing range of everyday products such as shampoos and socks. This situation is analogous to the previous use of antibiotics for nonmedical purposes and the subsequent spread of antibiotic resistant bacteria. This project will measure silver resistance selection pressure in key microbial communities. Novel monitoring devices, a multi-technique chemistry approach, and correlative synchrotron spectroscopy and molecular biology techniques will be used to decipher the environmental silver resistome and its likely significance.Read moreRead less

Growing global demands for water, food and energy will continue to intensify land-use conflicts, contribute to carbon emissions, and exacerbate threats to biodiversity. Consumption needs to be balanced with environmental protection. This project aims to frame the issues of food security, rural development, carbon emissions and biodiversity loss from the perspective of ecological and economic theory. It will use cutting-edge analyses to assess the implications and trade-offs of alternative land-use and development scenarios that reflect key socioeconomic and environmental priorities in Indonesia. Based on these analyses, decision-support tools will be developed to help Indonesian policymakers reconcile these objectives to achieve more sustainable development.Read moreRead less
Methods for establishing cumulative CO2 emission budgets for Australia. Limiting global warming requires curbing cumulative carbon emissions. However, we do not know how the quasi-linear relationship between cumulative carbon dioxide emissions and maximal warming is modulated by other climate-relevant gases (for example, sulphur oxide or Methane) nor have we quantified the relationship in sufficient detail for aligning national and international policy strategies. This project will develop new m ....Methods for establishing cumulative CO2 emission budgets for Australia. Limiting global warming requires curbing cumulative carbon emissions. However, we do not know how the quasi-linear relationship between cumulative carbon dioxide emissions and maximal warming is modulated by other climate-relevant gases (for example, sulphur oxide or Methane) nor have we quantified the relationship in sufficient detail for aligning national and international policy strategies. This project will develop new methods to establish global emission budgets for various climate targets and likelihoods. Options for Australia’s share will be quantified on the basis of effort-sharing proposals. This research is vital for Australian policy makers, the energy sector, and the public in order to plan for coming decades.Read moreRead less
The evolution of species traits and spread during biological invasions. Exotic species pose a dire threat to Australia's biodiversity and natural resources due to the speed at which non-indigenous pests spread and the ecological and environmental damage they are capable of causing. The proposed research, on identifying traits associated with the spread of exotic vertebrate species and modelling the reproductive and dispersal parameters among different populations, will provide new knowledge and ....The evolution of species traits and spread during biological invasions. Exotic species pose a dire threat to Australia's biodiversity and natural resources due to the speed at which non-indigenous pests spread and the ecological and environmental damage they are capable of causing. The proposed research, on identifying traits associated with the spread of exotic vertebrate species and modelling the reproductive and dispersal parameters among different populations, will provide new knowledge and aid in developing innovative solutions for arresting the spread of exotic species. The validation of current models of spread will represent a major and timely addition to the national research capability on exotic species, and add substantially to Australia's reputation as a global leader in evolutionary ecology.Read moreRead less

New knowledge of mechanisms underlying climate variability is expected to benefit fundamental research, while future-facing models will allow land managers and policy makers to better anticipate extraordinary climate events.Read moreRead less
Systems modelling for synergistic ecological-climate dynamics. The project aims to improve forecasts of the response of biodiversity to future climate change and so improve on-ground conservation management. A systems modelling framework will be developed and tested against real-world data to integrate a wide variety of biological and geophysical inputs and so produce more realistic predictions.
Integrating models with molecular 'logbooks' to better forecast extinction risk from climate change. Current forecasts indicate that human-driven climate change will likely cause widespread biodiversity loss. However, climatic shifts during the Quaternary (2.6 million years ago to present), similar in magnitude to those projected for the 21st century, did not apparently cause extensive extinctions (with the exception of the megafauna). This project aims to use models linked to past responses imp ....Integrating models with molecular 'logbooks' to better forecast extinction risk from climate change. Current forecasts indicate that human-driven climate change will likely cause widespread biodiversity loss. However, climatic shifts during the Quaternary (2.6 million years ago to present), similar in magnitude to those projected for the 21st century, did not apparently cause extensive extinctions (with the exception of the megafauna). This project aims to use models linked to past responses imprinted in species’ genes to resolve whether the disparity between observed and predicted extinction rates comes from models over-predicting species loss due to climate change. It will use this genetic-demographic approach to improve predictions of biodiversity responses to global change by establishing the biological and environmental determinants of extinction.Read moreRead less
