The effect of aerial spraying of two pesticides on semi-arid grasslands. The project will investigate how two pesticides, fipronil and metarrhizium, used to control locusts, affect semi-arid ecosystems by examining impacts on invertebrates, their predators, lizards and soil processes. The effects will be followed through time in a large scale experiment to determine recovery and compare each pesticide.
Optimising the spring in your step to enhance footwear design. This project aims to examine how the nervous system adjusts the mechanical function of our feet across a spectrum of speeds, from slow running through to maximal effort sprinting. The proposed research will explore how the nervous system controls the function of the foot to meet the ever-varying demands of locomotion in the real-world. Expected outcomes of this project are to determine if running shoes help or hinder the natural spri ....Optimising the spring in your step to enhance footwear design. This project aims to examine how the nervous system adjusts the mechanical function of our feet across a spectrum of speeds, from slow running through to maximal effort sprinting. The proposed research will explore how the nervous system controls the function of the foot to meet the ever-varying demands of locomotion in the real-world. Expected outcomes of this project are to determine if running shoes help or hinder the natural spring-like function of the foot. It will explain a conceptually novel design allowing shoes to support our feet, whilst harnessing the energetic benefits of the foot's spring-like function. This research has the potential to revolutionise athletic footwear design and has direct implications for enhanced performance in running athletes.Read moreRead less

Backyard bandicoots: Engaging community in urban bushland conservation. This project aims to develop a model for urban ecosystem function and restoration, by identifying resources used by urban bandicoots (quenda). Digging mammal species turn over substantial volumes of soil as they forage for invertebrates, subterranean fungi, and plant material. These ecosystem engineers contribute to water infiltration, nutrient cycling, increased soil microorganism function, and seedling recruitment. They spread hypogeous mycorrhizal fungi that contribute to plant nutrition, crucial in Australia's nutrient-poor soils. This research is expected to improve targeted plantings in bushland reserves, and identify and mitigate threats to bandicoots in cities.Read moreRead less
Mass-production of beneficial insects for commercial pest management - physicochemical definition of oviposition sites for development of cost-efficient artificial substrates. The mass-production of beneficial insects for commercial purposes demands the development of cost-effective techniques for breeding and distributing them to growers. Many predatory beneficial insects lay their eggs in sites that prevent effective mass culturing. To circumvent this difficulty, it should be possible to defin ....Mass-production of beneficial insects for commercial pest management - physicochemical definition of oviposition sites for development of cost-efficient artificial substrates. The mass-production of beneficial insects for commercial purposes demands the development of cost-effective techniques for breeding and distributing them to growers. Many predatory beneficial insects lay their eggs in sites that prevent effective mass culturing. To circumvent this difficulty, it should be possible to define such oviposition sites in chemical and physical terms, and then use the information to develop artificial substrates that are convenient for mass rearing the insects and for disseminating them to growers. We will use the mealybug predator Cryptolaemus montrouszieri to test the feasibility of this approach and to assess its application to other beneficial species.Read moreRead less

Humane Chemical Methods for Population Management of Highly Valued Large Mammals. In many countries valued wild and feral animals are nonetheless too numerous. Their population numbers must be controlled through fertility. Examples are koalas in Australia, deer and seals in North America, cattle in India and dogs in Thailand. We aim to develop benign implants for castration based upon the gonadotrophin releasing hormone (GnRH). These implants are easily administered. The outcomes will be to ....Humane Chemical Methods for Population Management of Highly Valued Large Mammals. In many countries valued wild and feral animals are nonetheless too numerous.

Buffering the ecosystem impact of invasive cane toads. This project aims to address the devastating ecological problems caused by invasive species, by developing a novel approach that does not rely upon eradicating the invader through training vulnerable native predators not to eat toxic cane toads. Expected outcomes of this project include building a broad coalition of conservation-focused groups, from private land-owners and local businesses through to Indigenous groups and government and non- ....Buffering the ecosystem impact of invasive cane toads. This project aims to address the devastating ecological problems caused by invasive species, by developing a novel approach that does not rely upon eradicating the invader through training vulnerable native predators not to eat toxic cane toads. Expected outcomes of this project include building a broad coalition of conservation-focused groups, from private land-owners and local businesses through to Indigenous groups and government and non-government agencies across the entire Kimberley region. It will also result in the evaluation of methods for deployment of taste-aversion at a landscape scale. This should provide significant benefits by conserving vulnerable fauna and building a powerful network within a region of high biodiversity in tropical Australia.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
Controlling cane toads by turning their own weapons against them. This project aims to prevent cane toads, which are causing ecological havoc across tropical Australia, from breeding successfully. Attempts to control toad populations have had little impact, but recent research has revealed a new possibility — exploiting the toads' own weapons for intraspecific conflict. Larval cane toads compete intensely with other larval cane toads and as a result, have evolved a way to kill off their competit ....Controlling cane toads by turning their own weapons against them. This project aims to prevent cane toads, which are causing ecological havoc across tropical Australia, from breeding successfully. Attempts to control toad populations have had little impact, but recent research has revealed a new possibility — exploiting the toads' own weapons for intraspecific conflict. Larval cane toads compete intensely with other larval cane toads and as a result, have evolved a way to kill off their competitors. Toad tadpoles produce chemicals that have devastating effects on younger members of their own species, but not on native species. By deploying those chemicals, this project could develop a novel and powerful form of invader control.Read moreRead less
Adaptive management of arid and semi-arid ecosystems. Australia’s arid zones contain some of the world’s most threatened ecosystems. Management must begin immediately, but our understanding of these fragile species and ecosystems is currently very limited. This project will develop and apply new research in Adaptive Management (“learning by doing”) to ensure the persistence of these rare places.
