A multispecies approach to managing feral animals in tropical savanna landscapes. Controlling invasive species is important for maintaining healthy landscapes. Often, multiple invasive species occupy a landscape and simultaneous management of them is required. Our innovative management tool will allow land managers to develop and implement control strategies for environmentally invasive species in Northern Australia and globally.
Surviving in a toad-colonised landscape: manipulating predator behaviour to reduce the impact of the cane toad invasion. Invasive species pose a major threat to biodiversity; and within Australia, cane toads are widely viewed as one of the biggest such problems. Vigorous attempts at toad control have failed to slow the invasion front, and toads are now entering the Kimberley region. If we can’t stop the toads, are there other ways to reduce the numbers of native predators killed by eating thes ....Surviving in a toad-colonised landscape: manipulating predator behaviour to reduce the impact of the cane toad invasion. Invasive species pose a major threat to biodiversity; and within Australia, cane toads are widely viewed as one of the biggest such problems. Vigorous attempts at toad control have failed to slow the invasion front, and toads are now entering the Kimberley region. If we can’t stop the toads, are there other ways to reduce the numbers of native predators killed by eating these poisonous invaders? Predators given nausea-inducing chemicals with their first toad meal rapidly learn to avoid cane toads as prey, enabling them to survive even where toads are present. The study will develop those methods for several vulnerable native species, including techniques for deployment of aversion-inducing baits in advance of the toad invasion.Read moreRead less
A landscape-scale experimental test of factors driving mammal declines in northern Australia. Australia has suffered the highest rate of modern mammal extinctions in the world. Foxes have been largely responsible for this extinction in southern Australia and probably also Central Australia. However the decline in mammals in northern Australia has occurred later than that in the south, and in the absence of foxes. We will adopt an experimental approach to determine the mechanisms driving mammal d ....A landscape-scale experimental test of factors driving mammal declines in northern Australia. Australia has suffered the highest rate of modern mammal extinctions in the world. Foxes have been largely responsible for this extinction in southern Australia and probably also Central Australia. However the decline in mammals in northern Australia has occurred later than that in the south, and in the absence of foxes. We will adopt an experimental approach to determine the mechanisms driving mammal declines and extinctions in northern Australia. Populations of brush-tail tree rats (Conilurus penicillatus) will be translocated to suitable habitat on mainland sites that experience different fire regimes and predation pressures.Read moreRead less
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
Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia ....Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia from invasive diseases. There is an urgency to undertake our research because global environmental change and increasing movements of people (particularly military personnel) from overseas regions where these diseases are endemic is increasing the vulnerability of northern Australia to the (re)establishment of mosquito borne diseases.Read moreRead less
Ecological-epidemiological models of feral swamp buffalo control in northern Australia. This research is locally, nationally and internationally significant because it 1) improves the capacity of the Northern Territory and its traditional aboriginal owners to manage together this prevalent species in an effort to minimise disturbance to native flora and fauna and to understand the long-term implications of continued proliferation, 2) provides a nationally relevant system to monitor and project t ....Ecological-epidemiological models of feral swamp buffalo control in northern Australia. This research is locally, nationally and internationally significant because it 1) improves the capacity of the Northern Territory and its traditional aboriginal owners to manage together this prevalent species in an effort to minimise disturbance to native flora and fauna and to understand the long-term implications of continued proliferation, 2) provides a nationally relevant system to monitor and project the spread of disease through feral animal populations in Australia, and 3) combines quantitative data and robust analytical tools that can be used as a template for solving many broad-scale feral animal problems around the world.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.

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
Bringing back Australia's lost woodland biodiversity: towards strategic multi-species reintroductions. Australia has the highest rate of mammal extinction of any continent on the planet. This has reduced biodiversity and compromised many important ecological processes. What is the best way to re-build depauperate mammal communities with multi-species reintroductions?

Australia has the highest rate of mammal extinction of any continent on the planet. This has reduced biodiversity and compromised many important ecological processes. What is the best way to re-build depauperate mammal communities with multi-species reintroductions? What effects do multi-species reintroductions have on recipient ecosystems? This project aims to explore these questions by reintroducing three mammal species to a critically endangered temperate woodland: a carnivore (the eastern quoll), an insectivore (yellow-footed antechinus), and a herbivore (the eastern chestnut mouse). Results from this sequenced multi-species reintroduction experiment will have broad applicability to ecosystem restoration in Australia and overseas.Read moreRead less
