Diagnosing river health using invertebrate traits and DNA barcodes. This project aims to develop indices that link change in invertebrate communities to specific environmental stressors, and combine these indices with innovative, low cost molecular approaches to species identification to rapidly identify the causes of decline. River health assessment methods, usually based on aquatic invertebrates, identify if rivers are impaired but must be developed to identify the causes of decline. The intended outcomes are improved sustainable water resource management within and among states, and improved natural resource policy development.Read moreRead less
Investigating movement, distribution, abundance and diet to support management objectives for threatened riverine predators in Northern Australia. The rivers and estuaries of northern Australia are highly productive environments, containing an exceptional diversity and abundance of large predatory aquatic species. This project aims to monitor the movements, habitat preferences and diet in eight large predatory species in a northern Queensland river over the next three years. Movement data will b ....Investigating movement, distribution, abundance and diet to support management objectives for threatened riverine predators in Northern Australia. The rivers and estuaries of northern Australia are highly productive environments, containing an exceptional diversity and abundance of large predatory aquatic species. This project aims to monitor the movements, habitat preferences and diet in eight large predatory species in a northern Queensland river over the next three years. Movement data will be combined with isotopic analysis to reveal how environmental and biological factors drive animal movements and impact habitat connectivity. In a world of vanishing top predators, it is imperative to understand system dynamics before we can evaluate the impact of species removal on ecosystem function.Read moreRead less
Cross-cultural management of freshwater on resource-constrained islands. This project aims to develop a methodology for community-led adaptive water management on resource-constrained islands and will involve Indigenous communities in the development of predictive groundwater models. The project plans to apply three-dimensional participatory mapping, a stakeholder engagement process led and owned by the local communities, on Milingimbi Island in the Northern Territory.

This project aims to develop a methodology for community-led adaptive water management on resource-constrained islands and will involve Indigenous communities in the development of predictive groundwater models. The project plans to apply three-dimensional participatory mapping, a stakeholder engagement process led and owned by the local communities, on Milingimbi Island in the Northern Territory. The extension of the participatory mapping with a subsurface component will then support the conceptualisation and development of a numerical model of the island's groundwater system. The predictive model and community engagement processes are expected to provide a more robust methodology for evaluating future water management plans. The project outcomes will contribute to solving water supply problems in remote communities in Australia, and overseas.Read moreRead less

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
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

Local reoptimization for turbocharging heuristics. Theoretical computer science has up until now had little impact on the design of effective heuristics. While data sets may be large, significant structure is almost always present and important to take into account when designing algorithms. Parameterised complexity considers the underlying structure by parameterising not only on the size of the input but also on structural parameters.

Theoretical computer science has up until now had little impact on the design of effective heuristics. While data sets may be large, significant structure is almost always present and important to take into account when designing algorithms. Parameterised complexity considers the underlying structure by parameterising not only on the size of the input but also on structural parameters. This project aims to take advantage of the many opportunities for new theories in the design of new heuristics and in turbocharging existing heuristics for computationally hard problems.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
Managing acid mine drainage in northern Australia using microbial mats.

One of the most difficult environmental issues for the mining industry is acid mine drainage (AMD) that can lead to significant environmental damage. This project aims to identify microbes and characterise their roles in AMD formation in north Australia. We will use our new knowledge to design and trial microbial mats for the treatment of AMD. A successful AMD microbial treatment technology will minimise the risk of acid runoff and metal seepage into rivers and through groundwater. AMD treatment technology we develop in the tropics where we experience the extremes of dry and wet seasons will require only minor modification to operate in temperate climates however the reverse is not true.
