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.
Ecological immunity in the Lepidoptera: unravelling the relationship between immune function, sperm quality, and reproductive success. The effect of juvenile immune challenge and an individual's population ecology on subsequent adult immune function, physiology and reproductive success is poorly understood, despite its ability to explain fundamental processes in sexual selection. This project will unravel the relationship between immune function, sperm quality, and reproductive success.
Bio-inspired camouflage to prevent shark attacks on surfers. Bio-inspired camouflage to prevent shark attacks on surfers. This project aims to develop a new shark deterrent technology to protect surfers and paddlers. Shark attacks are physically and emotionally devastating for the victims, and make the community disproportionately afraid. Surfers are at most risk of attack, but current surfboard-mounted deterrents are ineffective and not widely used. This project will build on the recent discove ....Bio-inspired camouflage to prevent shark attacks on surfers. Bio-inspired camouflage to prevent shark attacks on surfers. This project aims to develop a new shark deterrent technology to protect surfers and paddlers. Shark attacks are physically and emotionally devastating for the victims, and make the community disproportionately afraid. Surfers are at most risk of attack, but current surfboard-mounted deterrents are ineffective and not widely used. This project will build on the recent discovery that white sharks do not attack counter-illuminated (light emitting) seal-shaped decoys, and use new information about shark vision to understand why this ‘camouflage’ is so successful. This will also help to protect threatened shark species by reducing reliance on culling programs to keep people safe in the water.Read moreRead less
RoboCrab: An integrative approach to the natural ecology of decision making. The project aims to analyse and model the sophisticated and context-dependent escape behaviour of fiddler crabs under both natural conditions and in controlled laboratory settings. A crucial problem for biology is to understand how animals can make adaptive decisions in natural, complex sensory environments; such understanding also has direct application to robotics. The project plans to examine the effects of eye stabi ....RoboCrab: An integrative approach to the natural ecology of decision making. The project aims to analyse and model the sophisticated and context-dependent escape behaviour of fiddler crabs under both natural conditions and in controlled laboratory settings. A crucial problem for biology is to understand how animals can make adaptive decisions in natural, complex sensory environments; such understanding also has direct application to robotics. The project plans to examine the effects of eye stabilisation and oscillation, record from key neural stages using naturalistic stimuli to derive precise algorithms, and integrate and test the results on a robot model – RoboCrab. This may provide new insight into the integration of low-level sensory input with behavioural decision making circuits and the evolution of escape behaviours.Read moreRead less
The entrainment of circadian rhythms in marsupial mammals: behavioural and sub-cellular investigation of non-rod, non-cone ocular photoreceptors. Our investigation will provide a contribution to understanding the role that photoreceptors play in the mechanisms that control circadian rhythms and will ultimately lead to a better understanding of the basic physiology of sleep and circadian cycles, their contribution to learning and memory and their impact on waking performance. Targeted drug develo ....The entrainment of circadian rhythms in marsupial mammals: behavioural and sub-cellular investigation of non-rod, non-cone ocular photoreceptors. Our investigation will provide a contribution to understanding the role that photoreceptors play in the mechanisms that control circadian rhythms and will ultimately lead to a better understanding of the basic physiology of sleep and circadian cycles, their contribution to learning and memory and their impact on waking performance. Targeted drug development and the design of lighting systems effective in regulating circadian rhythms will improve the quality of life and competitiveness of the many citizens who endure abnormal sleep/wakefulness schedules.Read moreRead less
Aquatic eye design: sharks and rays as models of underwater colour and luminance vision. Sharks are usually assumed to be colour blind. We have discovered that they may in fact see colour very well and that the eyes of different species are adapted to their particular lifestyles. Our research will help to raise the profile of sharks and portray them as animals with advanced sensory systems and complex visual behaviours rather than just dangerous killing machines. Studying the vision of sharks m ....Aquatic eye design: sharks and rays as models of underwater colour and luminance vision. Sharks are usually assumed to be colour blind. We have discovered that they may in fact see colour very well and that the eyes of different species are adapted to their particular lifestyles. Our research will help to raise the profile of sharks and portray them as animals with advanced sensory systems and complex visual behaviours rather than just dangerous killing machines. Studying the vision of sharks may also help to reduce the number (currently >50,000) that are killed each year as bycatch by Australian long-line fisheries and make a valuable contribution to one of Australia's National Research Priorities (an Environmentally Sustainable Australia) for managing and conserving our biodiversity.Read moreRead less
