We will use advances in robotics, engineering, mathematics and biology to develop a new computer model for the control of one of the world's most damaging pest insects: locusts. Autonomous aerial robotic systems will be used to collect data on Australian plague locusts travelling in devastating migratory bands. These data on band movement and the behaviour of individual locusts within the band will be used to develop a particle physics-inspired predictive model of migratory band movement, which will be used to optimise locust control operations. Economic, environmental and social benefits will arise through reductions in the amount of time, money, manpower and insecticides necessary to combat locust outbreaks.Read moreRead less
Making Green Guard® greener: enhancing the efficacy of a biopesticide. The project aims to identify naturally occurring micro-organisms to increase the effectiveness of Green Guard ®, which is a biopesticide used against the Australian plague locust. The project will use next-generation sequencing and other molecular techniques to potentially identify candidate microbes or combinations of microbes that can be added to Green Guard to enhance locust susceptibility. The project also aims to quantif ....Making Green Guard® greener: enhancing the efficacy of a biopesticide. The project aims to identify naturally occurring micro-organisms to increase the effectiveness of Green Guard ®, which is a biopesticide used against the Australian plague locust. The project will use next-generation sequencing and other molecular techniques to potentially identify candidate microbes or combinations of microbes that can be added to Green Guard to enhance locust susceptibility. The project also aims to quantify the interactive impact of temperature and nutrition on immune function, disease resistance and host-plant quality of plague locusts; and to explore the combined effects of temperature, habitat and Green Guard, in combination with candidate microbes or pathogens, on the behaviour and collective movement of locusts. It is anticipated that this will have implications for management and control strategies.Read moreRead less
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

This project aims to investigate how bacteria can assist wildlife in adapting to the accelerating threat of environmental change. Using an innovative, interdisciplinary approach this project expects to identify interactions between environmental change and the diet, microbial communities and stress resilience of wildlife, using the threatened Grey-headed flying fox as a model system. Expected outcomes include detailed understanding of the role of microbial communities in shaping wildlife adaptations and development of ecological interventions to enhance wildlife resilience in Australia and globally. Such outcomes may reveal opportunities for management strategies that safeguard threatened species and reduce human-wildlife conflicts.Read moreRead less
Management of coastal lakes to minimise invasion. The European shore crab has the potential to undermine the productivity of Australia's estuaries and devastate our shellfish industries, worth over $50 million p.a. This project will provide estuarine managers with the data urgently needed to prevent spread of this pest species. In doing so, it will help to ensure the future prosperity of our seafood industries and the sustainability of our unique coastal biodiversity.

The European shore crab has the potential to undermine the productivity of Australia's estuaries and devastate our shellfish industries, worth over $50 million p.a. This project will provide estuarine managers with the data urgently needed to prevent spread of this pest species. In doing so, it will help to ensure the future prosperity of our seafood industries and the sustainability of our unique coastal biodiversity. The outcomes of this project will be applicable to the management of many of the > 200 introduced marine species already present within our coastal waters. Importantly, the project will also contribute to research training in new techniques to protect Australia from future pest invasions.Read moreRead less
From individuals to mass organisation: aggregation, synchronisation and collective movement in locusts. By combining field biology, robotics and mathematics, this project will determine how animals flock or swarm and, in particular, how locust nymphs control their collective movement over their lifetime. The mathematical models derived during the project will be directly applied to controlling outbreaks of locusts in Australia, South and North Africa.
Ecological impacts of QX Oyster disease and its management strategies. QX disease is responsible for mass mortality of oysters, and, as a result, economic and job losses. QX disease also threatens ecosystem services provided by wild oysters, such as biodiversity enhancement and fish production. This project will provide estuarine managers with information about how proposed QX management solutions will impact wild oyster populations and vital ecosystem services. It will also contribute to traini ....Ecological impacts of QX Oyster disease and its management strategies. QX disease is responsible for mass mortality of oysters, and, as a result, economic and job losses. QX disease also threatens ecosystem services provided by wild oysters, such as biodiversity enhancement and fish production. This project will provide estuarine managers with information about how proposed QX management solutions will impact wild oyster populations and vital ecosystem services. It will also contribute to training of early career researchers in strategies to ensure the sustainable use of Australia's biodiversity. As QX outbreaks appear to be increasing, this research and training is urgently needed to underpin management to ensure long-term sustainability of valuable estuarine resources.Read moreRead less

Summary
The nutritional regulation of food chain length in terrestrial arthropod communities. Little is known about how the behaviour of individual animals affects the structure and function of ecological communities. By quantifying the diet requirements of predators and comparing them to the nutrients in prey at different trophic levels, this project will test if nutrient-based foraging by predators regulates food chain length in arthropod communities.
What happens to coral reefs without cleaner fish? Marine 'mosquitoes' regularly attack coral reef fish, but are controlled by parasite-eating cleaner fish. Cleaners positively affect reef communities in many ways and this is disproportionate to their tiny size and low density. Their removal for aquarium trades may have staggering effects on reefs. The project will determine how cleaners cause such effects.

Invasion of communities by exotic plants is a significant threat to biodiversity globally. This proposal is to strengthen collaborative links between the Plant Invasion Research Laboratories of Leishman in Australia and Richardson in South Africa. Their current research seeks to understand strategies of invasive plants in novel environments using the framework of leaf carbon strategies. Australian plants invasive in South Africa and South African plants invasive in Australia provide an ideal model system. This collaborative research will enable better prediction of potential invaders, as well as providing important input for models of plant, ecosystem and biosphere responses to global change incorporating invasion dynamics.Read moreRead less
