Biologically-inspired detection, pursuit and interception of moving objects by unmanned aircraft systems. Although it is well known that aggressive honeybees are very effective at detecting, pursuing and intercepting moving targets, this behaviour has never been studied quantitatively. This project will use high-speed video cinematography to investigate this behaviour, to develop visual algorithms for the detection of moving targets, and to create dynamical models of the mechanisms that control ....Biologically-inspired detection, pursuit and interception of moving objects by unmanned aircraft systems. Although it is well known that aggressive honeybees are very effective at detecting, pursuing and intercepting moving targets, this behaviour has never been studied quantitatively. This project will use high-speed video cinematography to investigate this behaviour, to develop visual algorithms for the detection of moving targets, and to create dynamical models of the mechanisms that control pursuit. The resulting algorithms will be incorporated into unmanned aerial vehicles for detecting, monitoring and tracking other objects in the sky, and their performance will be evaluated. The results will provide a better understanding of the biological basis of pursuit behaviour, as well as lead to novel technologies for aerial surveillance and safety.Read moreRead less
Strategies for mid-air collision avoidance in aircraft: lessons from bird flight. Birds seldom collide with each other and other objects, despite the high speeds at which they fly in complex environments. This project will examine how birds sense and avoid impending collisions, and will use these results to design novel strategies for the detection and avoidance of aircraft mid-air collisions.
The ecology of trace metal contamination in native Australian mammals. The ecology of trace metal contamination in native Australian mammals . This project aims to evaluate the impacts of mined trace metals on the health and performance of native Australian mammals in a northern tropical ecosystem and to determine how each species’ ecology contributes to their risk of contamination. The research also aims to give local Indigenous Rangers scientifically based strategies to improve wildlife conser ....The ecology of trace metal contamination in native Australian mammals. The ecology of trace metal contamination in native Australian mammals . This project aims to evaluate the impacts of mined trace metals on the health and performance of native Australian mammals in a northern tropical ecosystem and to determine how each species’ ecology contributes to their risk of contamination. The research also aims to give local Indigenous Rangers scientifically based strategies to improve wildlife conservation on their island. Australia’s long-term health relies on its ability to minimise the environmental costs of mining, particularly in areas characterised by high biodiversity, unique native species, or species of cultural or touristic value. Anticipated outcomes are better, more targeted strategies for conservation in mining areas.Read moreRead less
An evolutionary approach to understanding chemical cues used in mate choice. This project will combine evolutionary biology with molecular and chemical ecology to gain a fundamental understanding of the role chemicals play in animal communication. By drawing on novel and innovative techniques, this project will place Australia at the forefront of this discipline and contribute to Australia's capacity to control pests.
Neural mechanisms of vestibular perception in zebrafish. This project aims to understand vestibular processing by removing physical movement. The vestibular system allows us to perceive gravity and movement, but it is not understood how the brain processes information from vestibular sensors in the inner ear. This project will exert forces on the zebrafish’s inner ear with a laser, stimulating the vestibular sense. This means that the animal will experience vestibular stimuli while stationary, a ....Neural mechanisms of vestibular perception in zebrafish. This project aims to understand vestibular processing by removing physical movement. The vestibular system allows us to perceive gravity and movement, but it is not understood how the brain processes information from vestibular sensors in the inner ear. This project will exert forces on the zebrafish’s inner ear with a laser, stimulating the vestibular sense. This means that the animal will experience vestibular stimuli while stationary, allowing calcium imaging of neurons that respond to vestibular cues and optogenetics to stimulate or silence these neurons. This is expected to reveal which cells and circuits mediate vestibular perception, processing and behaviour.Read moreRead less
The danger within: assessing the threats to an endangered finch from genetic incompatibility, limited dispersal and effective population size. The Gouldian finch has declined dramatically over the past half century and remains one of Australia's most threatened birds. This project will use some cutting edge genetic techniques to understand some of the processes that undermine the species' recovery and our ability to monitor current populations.
Neuro-ecology: information processing under natural conditions. Not enough is known about how sensory information is processed through the brain under natural environmental conditions. This project will shed light on how information processing changes with context and will help explain why even those animals with the smallest brains are much more versatile and robust than our most advanced robots.
Using performance to predict the survival of threatened mammals. This project aims to use a new mechanistic approach to quantify how the performance of cats and dingoes interacts with habitat complexity to drive population loss of prey species—namely, how the density of obstacles and refuges contributes to prey escape. Expected outcomes include discovering how rocky and savanna habitat structure affect the survival of threatened mammals hunted by cats and dingoes. It will provide a globally cust ....Using performance to predict the survival of threatened mammals. This project aims to use a new mechanistic approach to quantify how the performance of cats and dingoes interacts with habitat complexity to drive population loss of prey species—namely, how the density of obstacles and refuges contributes to prey escape. Expected outcomes include discovering how rocky and savanna habitat structure affect the survival of threatened mammals hunted by cats and dingoes. It will provide a globally customisable model, and inform management of an important Indigenous Protected Area.Read moreRead less
Threshold evolution: conceptualising decisions as traits. All organisms make decisions, yet the diversity of decision rules across the spectrum of life can be understood through a few key evolutionary models. This project will test these models and then apply them to understanding topics as diverse as pest outbreaks, human twinning, sex ratio evolution and disease spread as a consequence of climate change.
Social and environmental selection on female ornaments and armaments. Darwin's theory of sexual selection is remarkably successful in explaining how elaborate signals evolved in male animals, but it is unclear whether similar processes drive the evolution of female signals. This project aims to conduct empirical and comparative tests of hypotheses for female trait elaboration, capitalising on inter- and intra-specific variation in female signal form, social organisation and signalling environmen ....Social and environmental selection on female ornaments and armaments. Darwin's theory of sexual selection is remarkably successful in explaining how elaborate signals evolved in male animals, but it is unclear whether similar processes drive the evolution of female signals. This project aims to conduct empirical and comparative tests of hypotheses for female trait elaboration, capitalising on inter- and intra-specific variation in female signal form, social organisation and signalling environments. The project could generate new insight into the processes that promote and constrain phenotypic diversity in nature.Read moreRead less
