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

Beyond Hendra: the significance of viral communities in bat virus spillover. This project aims to address the emerging global health threat posed by zoonotic bat-borne viruses, by determining why bats shed multiple viruses in synchronised pulses. The project expects to identify universal drivers of multi-viral shedding pulses, using Hendra virus as a model system for other bat viruses in Australia and globally. Expected outcomes include insights into the interactions between environmental change ....Beyond Hendra: the significance of viral communities in bat virus spillover. This project aims to address the emerging global health threat posed by zoonotic bat-borne viruses, by determining why bats shed multiple viruses in synchronised pulses. The project expects to identify universal drivers of multi-viral shedding pulses, using Hendra virus as a model system for other bat viruses in Australia and globally. Expected outcomes include insights into the interactions between environmental change, bat ecology, viral dynamics and spillover, prediction of when and where bat viral shedding will most likely occur, and development of new ecological interventions to prevent bat virus spillover in Australia and globally. This will provide significant benefits by pre-empting spillover and global pandemics before they occur.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 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
Pheromone evolution and ecology in insects on intra- and inter-specific scales. The study of pheromones is important because so many insect pests use them as part of their reproductive life cycle, increasing their potential to cause damage to crops and other natural products. My research will improve our understanding of the evolution of pheromones and communication by smell, a subject that has been largely neglected by evolutionary biologists. More specifically, by identifying the ecological fa ....Pheromone evolution and ecology in insects on intra- and inter-specific scales. The study of pheromones is important because so many insect pests use them as part of their reproductive life cycle, increasing their potential to cause damage to crops and other natural products. My research will improve our understanding of the evolution of pheromones and communication by smell, a subject that has been largely neglected by evolutionary biologists. More specifically, by identifying the ecological factors that influence pheromone evolution, the research will help to assess the long-term consequences of the control measures currently used against such pests and, in particular, will have direct applications to the prevention of damage to Australian pine plantations by the invasive five-spined bark beetle, Ips grandicollis.

The effect of dissolved organic matter on the toxicity and bioavailability of metals in tropical freshwater ecosystems. Mine waste materials in tropical Australia, including historical, current and future operations, represent one of the threats to the quality and biodiversity of tropical freshwater ecosystems. Dissolved organic carbon (DOC) is thought to influence metal toxicity. In order to adequately understand the risks of priority metals and metalloids from mining and other activities (eg. ....The effect of dissolved organic matter on the toxicity and bioavailability of metals in tropical freshwater ecosystems. Mine waste materials in tropical Australia, including historical, current and future operations, represent one of the threats to the quality and biodiversity of tropical freshwater ecosystems. Dissolved organic carbon (DOC) is thought to influence metal toxicity. In order to adequately understand the risks of priority metals and metalloids from mining and other activities (eg. urban development) to tropical freshwater ecosystems, it is essential that the role of DOC is quantified. The outcomes of this project will provide improved metal risk assessment methodologies; quantitative understanding of the relationship between DOC and the bioavailability and toxicity of key metals such arsenic, aluminium, cadmium, copper, uranium and zinc.Read moreRead less

This project aims to quantify the overall nitrogen budget and its influencing factors in Australia; benchmark Australian performance against other nations; assess the costs and benefits of reactive nitrogen (Nr) use; and analyse policy settings and their feasibility for addressing the challenges of Australian Nr management. Nr, if poorly managed, can cause significant environmental degradation, but is essential for ecosystems, especially agro-ecosystems. The project expects to provide a framework for the future sustainable use of Nr in relation to food production, environment protection and climate change in dry regions.Read moreRead less
Avian migrants as vectors of zoonotic diseases in a changing world. There is an urgent need to understand the role of migratory birds in spreading avian influenza and other diseases. This project focuses on the effect of global change on the interactions between avian influenza and threatened waders migrating between the Arctic, Asia and Australia. This project will help us assess and manage the health risks to man and birds alike.

Using ancient microbiomes and genomes to reconstruct human history. This project aims to generate unique insights into the processes and history that produced the current distribution of modern humans and the bacteria we carry with us (our microbiome). The project will use combined signals of bacterial, genomic and climate data to reconstruct the impacts of migrations, changes in diet, environment, and health in different parts of the world. A key aspect will be the creation of a program to map the genetic history of indigenous Australia, and the impacts of colonisation on indigenous people around the world. Research advances will be transferred to Early Career Researchers through an innovative program of workshops, and the resulting data will be used to create a new format for Australian genetic databases.Read moreRead less
Factors controlling marine food webs: consumer vs. nutrient limitation of mobile invertebrates and algae. An understanding of the strength of interactions in marine food webs is crucial to predicting change in coastal habitats due to human activities. The outcomes of this research will indicate the relative importance of changes in nutrient inputs from terrestrial runoff (eutrophication) and predation pressures (via overfishing) - both of which may strongly affect the structure of marine habitat ....Factors controlling marine food webs: consumer vs. nutrient limitation of mobile invertebrates and algae.
