Cane toads in southern Australia: invasion dynamics and options for control. This project aims to investigate the spread of cane toads through southern Australia, an invasion front that has attracted far less research than the same species’ expansion through tropical regions, even though toads severely impact native wildlife in both areas. This project expects to generate new knowledge to determine why the rate of toad invasion is so much slower in New South Wales than in the tropics, and how be ....Cane toads in southern Australia: invasion dynamics and options for control. This project aims to investigate the spread of cane toads through southern Australia, an invasion front that has attracted far less research than the same species’ expansion through tropical regions, even though toads severely impact native wildlife in both areas. This project expects to generate new knowledge to determine why the rate of toad invasion is so much slower in New South Wales than in the tropics, and how best to modify newly-developed approaches to toad control to the conditions in southern Australia. Expected outcomes include predicting future trajectories of expansion, and identifying optimal approaches to toad control and impact mitigation. This should provide significant benefits for biodiversity conservation.Read moreRead less
Call Out and Listen In: A New Way to Detect and Control Invasive Species. This project aims to use novel acoustic techniques to detect and capture invasive frog species to protect native species. Invasive frogs are an under-appreciated but serious ecological problem worldwide, because they are voracious predators and are often toxic to native species. Male frogs call to attract mates, and answer calls they hear. Using new acoustic technologies, these behaviours can be exploited to detect species ....Call Out and Listen In: A New Way to Detect and Control Invasive Species. This project aims to use novel acoustic techniques to detect and capture invasive frog species to protect native species. Invasive frogs are an under-appreciated but serious ecological problem worldwide, because they are voracious predators and are often toxic to native species. Male frogs call to attract mates, and answer calls they hear. Using new acoustic technologies, these behaviours can be exploited to detect species and attract gravid females for removal. This project aims to combine an early warning system (electronic listening) and trap (calling and catching), which can be customised to any invasive frog, and use it to detect and remove cane toads, especially in low density populations.Read moreRead less
Either side of the Big Wet: the future resilience of south-eastern Australia's biota. Australia must develop strategies for managing its biodiversity under climate changes expected to occur under projected Intergovernmental Panel on Climate Change (IPCC) emission scenarios. The project will furnish comprehensive data on the response of plants and animals to the break in the Big Dry (1997-2009) in 2010-11 and evaluate how predict biotic components will cope with future climates.
Preventing and reversing population declines of northern quolls. This project seeks to develop novel effective strategies to halt and reverse declines in northern quolls by improving their ‘toad-smart’ behaviour. The spread of cane toads threaten northern quolls, which are marsupial predators. We cannot halt the toad invasion, but we can train quolls not to eat cane toads. Trained quolls can survive long term in toad-infested landscapes, and their offspring can learn not to eat toads. This proje ....Preventing and reversing population declines of northern quolls.

Trained quolls can survive long term in toad-infested landscapes, and their offspring can learn not to eat toads. This project builds on this work by focusing on cultural and genetic transmission of toad-smart behaviour. The project could save numerous quoll populations from extinction.Read moreRead less

Summary
What fire regimes can maintain biodiversity in northern Australia's savannah landscapes, and how do we implement them? Inappropriate fire regimes (the frequency, intensity and size of bushfires) are causing ongoing declines in Australia's biodiversity, yet we have little understanding of the fire regimes that should be implemented. Focussing on Kakadu National Park in northern Australia, this project will develop optimal fire management strategies for conserving biodiversity.
School drug education for junior high school students in Victoria - Assessing the impact of a state-wide, evidence-based intervention
. Young people are faced with numerous and powerful influences to use both legal and illicit drugs, and drug education can play an important counterbalancing role in shaping a normative culture of safety, moderation and informed decision making in this group. The research will develop, implement and evaluate one all encompassing, evidence-based, drug education pr ....School drug education for junior high school students in Victoria - Assessing the impact of a state-wide, evidence-based intervention
. Young people are faced with numerous and powerful influences to use both legal and illicit drugs, and drug education can play an important counterbalancing role in shaping a normative culture of safety, moderation and informed decision making in this group. The research will develop, implement and evaluate one all encompassing, evidence-based, drug education program for junior high school students across Victoria. The study is unique in its size and scope and will be of national benefit because its findings will influence the nature of future drug education in all secondary schools in Australia.Read moreRead less

The ecology of trace metal contamination in native Australian mammals . This project aims to evaluate the impacts of mined trace metals on the health and performance of native Australian mammals in a northern tropical ecosystem and to determine how each species’ ecology contributes to their risk of contamination. The research also aims to give local Indigenous Rangers scientifically based strategies to improve wildlife conservation on their island. Australia’s long-term health relies on its ability to minimise the environmental costs of mining, particularly in areas characterised by high biodiversity, unique native species, or species of cultural or touristic value. Anticipated outcomes are better, more targeted strategies for conservation in mining areas.Read moreRead less
What is 'natural'?: Locating and deciphering pre-human records of vegetation from northern Australian savannahs. The nature and magnitude of the environmental impact of human colonisation of Australia are fundamental issues in Australian prehistory and ecology. The project will locate and develop archives of environmental change from sinkholes in the Northern Territory that date back to the Last interglacial - a period which had a similar climate to the present day, but was before humans arrived ....What is 'natural'?: Locating and deciphering pre-human records of vegetation from northern Australian savannahs.

Impacts of global environmental change on biodiversity of tropical savannas. This project aims to predict the biodiversity consequences of a global trend of increasing woody cover in tropical savannas. Believed to be driven by a combination of elevated atmospheric CO2 concentration, climate change and management actions including fire suppression and cattle grazing. Expected outcomes are the integration of a range of modelling approaches to predict long-term impacts of environmental change on sa ....Impacts of global environmental change on biodiversity of tropical savannas. This project aims to predict the biodiversity consequences of a global trend of increasing woody cover in tropical savannas. Believed to be driven by a combination of elevated atmospheric CO2 concentration, climate change and management actions including fire suppression and cattle grazing. Expected outcomes are the integration of a range of modelling approaches to predict long-term impacts of environmental change on savanna biodiversity and the identification of land-use and management strategies to best mitigate these impacts. Likely benefits are an improved understanding of trade-offs between alternative land-uses in the savannas, including biodiversity conservation, fire management for carbon credits, and cattle grazing.Read moreRead less
Arresting declines of arboreal mammals in the tropical savannas. This project aims to evaluate the hypothesis that arboreal species are limited by the abundance of tree hollows, and that historical increases in the frequency of intense fires may be reducing hollow abundance. Northern Australia’s mammals are in severe decline, and arboreal species are among those that have fared worst. There is abundant anecdotal evidence that a decline in hollow abundance is the cause. Working with the Western A ....Arresting declines of arboreal mammals in the tropical savannas. This project aims to evaluate the hypothesis that arboreal species are limited by the abundance of tree hollows, and that historical increases in the frequency of intense fires may be reducing hollow abundance. Northern Australia’s mammals are in severe decline, and arboreal species are among those that have fared worst. There is abundant anecdotal evidence that a decline in hollow abundance is the cause. Working with the Western Australian Department of Parks and Wildlife in the Kimberley, the last region on the Australian mainland with an intact mammal fauna, the project aims to explore management options for increasing the availability of hollow denning sites for arboreal mammals (e.g. fire management, artificial nest boxes), and evaluate the likely impact of such actions on mammal populations across northern Australia.Read moreRead less
