The ecological dynamics of secreted bacteriocins and the evolution of multiple bacteriocin production in Escherichia coli. Bacteria produce compounds known as bacteriocins that are toxic to other microorganisms. The success of bacteria as bio-control agents and in probiotic formulations for the control microbial pathogens is, in part, due to bacteriocins. Bacteriocins may also have a role as replacements for traditional antibiotics and as natural food preservatives. The potential usefulness of b ....The ecological dynamics of secreted bacteriocins and the evolution of multiple bacteriocin production in Escherichia coli. Bacteria produce compounds known as bacteriocins that are toxic to other microorganisms. The success of bacteria as bio-control agents and in probiotic formulations for the control microbial pathogens is, in part, due to bacteriocins. Bacteriocins may also have a role as replacements for traditional antibiotics and as natural food preservatives. The potential usefulness of bacteriocins as the active agent in bio-control agents, as antibiotic replacements, as food preservatives, and as part of the repertoire of traits in probiotic formulations requires a sound understanding of the eco-evolutionary dynamics of bacteriocins. Understanding the ecology and evolution of bacteriocins is the goal of the proposed research.Read moreRead less
Discovering how termites use vibrations to make foraging decisions. Termites are pests affecting one third of Australian homes. The annual cost of treatment and damage repair is over $20 billion worldwide. Yet, little is known about how termites make foraging decisions based on vibrations. This project will study the key features in vibration signals produced by termites to unlock the secrets of their foraging behaviour.
Does size really matter? Selection, constraints and allometry. Australia is internationally recognized for its strong performance in evolutionary biology and quantitative genetics. This study contributes to the advancement of these fields. It is explicitly designed to create selection lines that can be used by developmental biologists, physiologists, geneticists and endocrinologists. This will strengthen links between institutes within Australia and internationally and later allow more applied q ....Does size really matter? Selection, constraints and allometry. Australia is internationally recognized for its strong performance in evolutionary biology and quantitative genetics. This study contributes to the advancement of these fields. It is explicitly designed to create selection lines that can be used by developmental biologists, physiologists, geneticists and endocrinologists. This will strengthen links between institutes within Australia and internationally and later allow more applied questions to be asked. Although this study addresses a basic research question, it uses techniques and statistics that are integral to work selecting for improvement of commercial crops and animals. It therefore provides valuable training opportunities for an essential part of Australia's agricultural sector.Read moreRead less
New quantum and robust control theory with applications to quantum optics. The application of quantum mechanics to the creation of quantum technology promises to be one of the most exciting technological developments of this century. Possible applications of quantum technologies include vastly improved sensors to search for minerals or gravity waves, secure quantum cryptography, and quantum computing. Quantum feedback control is a key tool in quantum technology. This project will lay the fou ....New quantum and robust control theory with applications to quantum optics. The application of quantum mechanics to the creation of quantum technology promises to be one of the most exciting technological developments of this century. Possible applications of quantum technologies include vastly improved sensors to search for minerals or gravity waves, secure quantum cryptography, and quantum computing. Quantum feedback control is a key tool in quantum technology. This project will lay the foundations of systematic theories of robust, coherent and nonlinear quantum feedback control and lead to advances in the control of highly resonant systems which underlie experimental quantum and nano technology. This will enable Australia to reap great benefits as this new technological area emerges.Read moreRead less
What drives parasite spread through social networks: lessons from lizards. Australia's biodiversity is continually threatened by new epidemics of local and foreign diseases and parasites. This project will enhance our understanding of how these diseases spread, allowing more effective controls to be developed to protect wildlife species, animal populations and, ultimately, Australian ecosystems.
Parasite transmission through social networks in the pygmy bluetongue lizard. Australia's biodiversity is continually threatened by new epidemics of diseases and parasites, some local, others from overseas. This project will provide information on how they spread so that more effective management of these diseases can be developed to protect wildlife species, animal populations and, ultimately, Australian ecosystems.
Renewable energy generation from flow-induced vibration. Much engineering effort has been expended to eliminate vibration of marine structures. This project seeks to provide the basis for the development of tidal energy harnessing, by deliberately amplifying and harnessing vibration. This technology offers the promise of capturing clean, zero-emissions energy, while presenting no risk to marine life.
The social determinants of childhood injury. Child hood injury is a preventable problem of major importance. This project will provide a comprehensive, research-based policy solution that will minimise death and disability among children zero to three years of age.
Image-based teleoperation of semi-autonomous robotic vehicles. This project will contribute strongly to Australia's robotic service industry in the development of semi-autonomous robotic inspection vehicles by; developing core technology in image-based teleoperation, training experts in the area, promoting the study of this topic within the Australian academia, and developing test facilities and prototype vehicles. Robotic inspection vehicles have the potential to replace direct human presence i ....Image-based teleoperation of semi-autonomous robotic vehicles. This project will contribute strongly to Australia's robotic service industry in the development of semi-autonomous robotic inspection vehicles by; developing core technology in image-based teleoperation, training experts in the area, promoting the study of this topic within the Australian academia, and developing test facilities and prototype vehicles. Robotic inspection vehicles have the potential to replace direct human presence in difficult, dangerous or simply uncomfortable inspection tasks such as; inspection of industrial pressure vessels, piping and conduits in factories or mines, undersea cabling, inspection of bridges, dams and other large scale civil buildings, amongst many other possibilities.Read moreRead less
Defining the evolution of pathogen virulence to enhance rabbit biocontrol. Rabbits impose a major economic and ecological burden on Australia. Biocontrols involving viruses are the best means to regulate rabbit populations, although they often have transient effectiveness. It is therefore essential to determine why some viruses retain the high virulence essential for effective biocontrol, while others are consistently benign. Through bioinformatic and experimental studies of two rabbit viruses w ....Defining the evolution of pathogen virulence to enhance rabbit biocontrol. Rabbits impose a major economic and ecological burden on Australia. Biocontrols involving viruses are the best means to regulate rabbit populations, although they often have transient effectiveness. It is therefore essential to determine why some viruses retain the high virulence essential for effective biocontrol, while others are consistently benign. Through bioinformatic and experimental studies of two rabbit viruses with markedly different virulence, Rabbit Haemorrhagic Disease virus (high virulence) and Australian rabbit calicivirus (low virulence), this project will determine the molecular mechanisms that control virulence and the factors that shape virulence evolution. Ultimately, this research will help improve rabbit biocontrol in Australia.Read moreRead less
