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
Colour vision in marsupials. The ability to distinguish colours is a crucial aspect of vision, providing vital data for sexual selection, predator detection and food acquisition. Studies of mammalian colour vision have largely overlooked marsupials. Our recent investigation of spectral sensitivity in two Australian species revealed a colour discrimination capacity beyond that of placentals (excluding primates), implying disparate evolutionary pressures in the two groups. We will provide the fi ....Colour vision in marsupials. The ability to distinguish colours is a crucial aspect of vision, providing vital data for sexual selection, predator detection and food acquisition. Studies of mammalian colour vision have largely overlooked marsupials. Our recent investigation of spectral sensitivity in two Australian species revealed a colour discrimination capacity beyond that of placentals (excluding primates), implying disparate evolutionary pressures in the two groups. We will provide the first comprehensive description of colour vision in marsupials, studying species with differing rhythmicities, habitats and diets. Wavelength sensitivity and molecular structure of retinal visual pigments will be assessed in relation to evolutionary influences and ecological demands.

Evolution and function of colour vision in mammals. The project aims to investigate colour vision in marsupials and monotremes (echidna and platypus) with differing phylogenies and biogeographic histories. Improving knowledge of the molecular structure of opsin genes mediating colour vision will be crucial to the understanding of evolution and function of this key mammalian (including human) sensory capacity. Understanding species colour discrimination will contribute to protective measures of ....Evolution and function of colour vision in mammals. The project aims to investigate colour vision in marsupials and monotremes (echidna and platypus) with differing phylogenies and biogeographic histories. Improving knowledge of the molecular structure of opsin genes mediating colour vision will be crucial to the understanding of evolution and function of this key mammalian (including human) sensory capacity. Understanding species colour discrimination will contribute to protective measures of Australia's unique fauna, presenting social and economic assets for the local and national community, and will set a standard that should be applied world-wide. Close international links and intellectual exchange will be invaluable to the Australian science community, including students.

Colour vision in birds: consequences to fatal collisions with wind farms. Wind-farms represent a key component of sustainable energy generation world-wide. However, many birds die as a result of collisions with wind-farms, posing an unsolved and controversial conservation issue. The proliferation of wind-farms in Australia will exacerbate the problem. Birds rely on vision to negotiate static and moving objects. Wind-farms, currently coloured to meet human aesthetic criteria, may be 'invisible' t ....Colour vision in birds: consequences to fatal collisions with wind farms. Wind-farms represent a key component of sustainable energy generation world-wide. However, many birds die as a result of collisions with wind-farms, posing an unsolved and controversial conservation issue. The proliferation of wind-farms in Australia will exacerbate the problem. Birds rely on vision to negotiate static and moving objects. Wind-farms, currently coloured to meet human aesthetic criteria, may be 'invisible' to birds since they see colours differently from humans. We will determine bird spectral sensitivities and compare them to the spectral reflectance of wind-farms. We will then develop modifications improving the visibility of wind-farms to birds, thereby reducing fatalities.Read moreRead less
Deep Downunder: designing a deep-sea exploration and discovery capability for Australia. Exploration of the deep-sea with the modern technologies to be developed by Deep-Downunder is a first for Australia. We aim to explore and discover life at depths from 50-3000m off The Great Barrier Reef, around the seamounts of Lord Howe Island and Tasmania and in the deep canyons of WA and SA. We expect to discover new species, hope for a glimpse of giant squid at home and will answer specific questions on ....Deep Downunder: designing a deep-sea exploration and discovery capability for Australia. Exploration of the deep-sea with the modern technologies to be developed by Deep-Downunder is a first for Australia. We aim to explore and discover life at depths from 50-3000m off The Great Barrier Reef, around the seamounts of Lord Howe Island and Tasmania and in the deep canyons of WA and SA. We expect to discover new species, hope for a glimpse of giant squid at home and will answer specific questions on Australia's ocean biology, fisheries and biotechnology never before approachable. To be effective guardians of Australian waters we must learn what lies in the depths we can't see from a boat.Read moreRead less
