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. 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.

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
From prediction to adaptation: responding to rapid ecosystem shifts under climate change. Nobody knows exactly how climate change will affect the ecosystems on which we depend for our own existence, though negative impacts are widely predicted. This project integrates mathematical, economic and ecological approaches to learn about the most effective way to spend limited funds for sustaining ecosystems threatened by climate change.
Where's the beef? A systems model for taming a wicked environmental problem. Demand for beef is increasing dramatically, particularly in Asia. This project aims to build systems models of local environmental impacts of beef production coupled with models of global beef trade to analyse production and policy scenarios. Beef is the food commodity with the largest ecological footprint, and increased production will have globally significant impacts on land and water resources, biodiversity, and cli ....Where's the beef? A systems model for taming a wicked environmental problem. Demand for beef is increasing dramatically, particularly in Asia. This project aims to build systems models of local environmental impacts of beef production coupled with models of global beef trade to analyse production and policy scenarios. Beef is the food commodity with the largest ecological footprint, and increased production will have globally significant impacts on land and water resources, biodiversity, and climate. The scale of these impacts depends on where and how cattle production occurs. Outcomes of this research include a framework for projecting regional and global ecological impacts of domestic cattle production policies, allowing informed decisions that consider and benefit environmental and socio-economic values.Read moreRead less

Summary
Catastrophic shifts: the value of knowing more about ecosystem feedbacks. Ecosystems respond to gradual change in unexpected ways. Feedback processes between different parts of an environment can perpetuate ecosystem collapse, leading to potentially irreversible biodiversity loss. However, it is unclear if greater knowledge of feedbacks will ultimately change environmental decisions. The project aims to identify when feedbacks matter for environmental decisions, by generating new methods that pr ....Catastrophic shifts: the value of knowing more about ecosystem feedbacks. Ecosystems respond to gradual change in unexpected ways. Feedback processes between different parts of an environment can perpetuate ecosystem collapse, leading to potentially irreversible biodiversity loss. However, it is unclear if greater knowledge of feedbacks will ultimately change environmental decisions. The project aims to identify when feedbacks matter for environmental decisions, by generating new methods that predict the economic benefit of knowing more about feedbacks. Combining ecological modelling and value-of-information theory, the outcomes of these novel methods will provide significant and broad environmental benefits, by enabling managers to make informed decisions and stay one step ahead of potential ecosystem collapse.Read moreRead less

The overarching aim of the ARC Centre of Excellence for Integrated Coral Reef Studies is to provide the scientific knowledge necessary for sustaining ecosystem goods and services of the worlds coral reefs, which support the livelihoods and food security of millions of people in the tropics. The Centre will enhance Australia's global leadership in coral reef science through three ambitious research programs addressing the future of coral reefs and their ability to adapt to change. A key outcome of the research will be providing tangible benefits to all Australians by building bridges between the natural and social sciences, strengthening capacity, and informing and supporting transformative changes in coral reef governance and management.Read moreRead less
Conservation of tropical forests for their carbon and biodiversity values. International efforts to save tropical forests for the carbon they store could help mitigate climate change and biodiversity loss. This project will aid these efforts by developing methods to model future deforestation and extending decision theory for the new challenges presented by international carbon-payment schemes.
Resilience of Coral Reef Ecosystems to Climate Change. Science-based management of coral reefs provides enormous environmental, social and economic benefit to Australia and other tropical maritime nations. The proposed research will provide scientific knowledge and research training that underpins the management and long-term sustainability of Australian reef resources.

Science-based management of coral reefs provides enormous environmental, social and economic benefit to Australia and other tropical maritime nations. The proposed research will provide scientific knowledge and research training that underpins the management and long-term sustainability of Australian reef resources. Climate change research is vital for supporting the sustainable use of the ecosystem goods and services provided by reef ecosystems (e.g. to tourism and fishing industries, recreational users and indigenous Australians). This research will place Australia in the forefront of understanding and responding to the regional-scale impacts of climate change on tropical societies and economies.Read moreRead less
Designing effective fish-friendly waterway culverts: integration of hydrodynamics and swimming performance. Man-made in-stream structures (for example, dams and road crossings) have contributed to major declines in native fish numbers, with more than 6,000 barriers to fish migration occurring in New South Wales alone. Recognising this, Fisheries New South Wales led the development of national guidelines for the design and construction of fish friendly road crossings. Unfortunately, these guideli ....Designing effective fish-friendly waterway culverts: integration of hydrodynamics and swimming performance. Man-made in-stream structures (for example, dams and road crossings) have contributed to major declines in native fish numbers, with more than 6,000 barriers to fish migration occurring in New South Wales alone. Recognising this, Fisheries New South Wales led the development of national guidelines for the design and construction of fish friendly road crossings. Unfortunately, these guidelines have little empirical backing. This project will integrate data on the swimming ability of Australian fish species with culvert hydrodynamic modelling to better understand fish requirements in and around road crossings. These data will strengthen national design guidelines and provide the tools engineers and planners need to balance fish migration with effective water management.Read moreRead less
Predicting coastal ecological futures in an era of unprecedented change. This project aims to show how we can predict the future for coastal habitats, fisheries and biodiversity, and validate the reliability of those predictions. Global change means ecosystems are rapidly changing beyond the bounds of historical data, so we can no longer extrapolate past trajectories to predict the future.

This project aims to show how we can predict the future for coastal habitats, fisheries and biodiversity, and validate the reliability of those predictions. Global change means ecosystems are rapidly changing beyond the bounds of historical data, so we can no longer extrapolate past trajectories to predict the future. Reliable predictions are needed to help managers mitigate the risks of future human activities to the environment. Expected outcomes are improved techniques for making predictions that can inform the adaptive management of ecosystems. This is expected to benefit the management of the coastal zone, including fisheries and habitat restoration, which will contribute to enhancing Australia’s valuable ocean economy. Read moreRead less
Recovering Australia’s migratory shorebirds. This project seeks to determine how Australia’s coastal environments can be managed to aid in the recovery of threatened shorebird species. Millions of migratory shorebirds arrive in Australia each year from their Arctic breeding grounds, yet many of these iconic species are in rapid decline, and two were recently nominated as nationally threatened in Australia. Recovering these threatened species is an important priority. The project aims to discover ....Recovering Australia’s migratory shorebirds. This project seeks to determine how Australia’s coastal environments can be managed to aid in the recovery of threatened shorebird species. Millions of migratory shorebirds arrive in Australia each year from their Arctic breeding grounds, yet many of these iconic species are in rapid decline, and two were recently nominated as nationally threatened in Australia. Recovering these threatened species is an important priority. The project aims to discover when and where to act to recover declining migratory species. It also plans to assess the strength of protective mechanisms already in place in Australia and overseas to protect migratory species from extinction, and determine how to improve protection for migrants when they arrive on Australia’s shores.Read moreRead less
