Honeybee Vision and navigation, and applications to robotics. Anyone observing a honeybee find its way home effortlessly after collecting nectar would know that these insects are excellent navigators, despite their diminutive brains and relatively simple nervous systems. One aim of this proposal is to gain a better understanding of the mechanisms underling honeybee navigation.

Anyone observing a honeybee find its way home effortlessly after collecting nectar would know that these insects are excellent navigators, despite their diminutive brains and relatively simple nervous systems. One aim of this proposal is to gain a better understanding of the mechanisms underling honeybee navigation. Another aim is to apply some of these findings to the development of novel, biologically inspired naviagtion systems for aircraft. The findings should illuminate important principles of animal navigation. They should also advance Australia's technology in the area of unmanned aerial vehicles (UAVs), which will have important applications in national defence and security.Read moreRead less

Vision provides a window into the brain, for studying perception, cognition and consciousness. It is integral to human cultural and social development. It provides opportunities for technological advances in diagnostics, artificial vision, robotics, and surveillance. Vision is therefore crucial to three of the National Priority Areas. The National Vision Network will create a coherent, interactive and innovative research base in the vision sciences, linked to end-users in areas ranging from the art, entertainment and fashion industries, through health and education, to border protection and counter-terrorism.Read moreRead less
Diversity out of a hybrid zone: the interplay of reinforcement and sexual selection in the formation of new species. How are there so many different species? Understanding how new species arise is a fundamental question because it explains current biodiversity and reveals the processes that will continue to give rise to new species in the future. An integral part of any animal species is who they choose to mate with, but how mate choice evolves to create new species remains poorly understood.

Understanding how new species arise is a fundamental question because it explains current biodiversity and reveals the processes that will continue to give rise to new species in the future. An integral part of any animal species is who they choose to mate with, but how mate choice evolves to create new species remains poorly understood. Here I will be studying the processes that affect the evolution of mate choice in an Australian rainforest frog hybrid zone. This system is uniquely suitable for providing internationally important insights into the evolutionary processes that form new species.Read moreRead less
Escalation of a coevolutionary arms race between cuckoos and their hosts: cognitive causes and evolutionary consequences. Cuckoos lay their eggs in the nests of other species, provoking an evolutionary arms race in which hosts evolve defences against parasitism and cuckoos evolve ever more cunning tricks to gain reproductive success. In principle, the degree of specialization required to defeat host defences could cause cuckoo speciation. Our previous research has revealed that the arms race bet ....Escalation of a coevolutionary arms race between cuckoos and their hosts: cognitive causes and evolutionary consequences. Cuckoos lay their eggs in the nests of other species, provoking an evolutionary arms race in which hosts evolve defences against parasitism and cuckoos evolve ever more cunning tricks to gain reproductive success. In principle, the degree of specialization required to defeat host defences could cause cuckoo speciation. Our previous research has revealed that the arms race between the Horsfield's bronze-cuckoo and its superb fairy-wren host has reached a uniquely advanced stage, hitherto undescribed, and previously thought imposssible to attain. We aim to investigate the mechanisms underlying this specialization and investigate whether it is driving speciation of the Chrysococcyx cuckoos.Read moreRead less
A multidisciplinary research program to assess limiting factors and predict impacts of climate change for endangered Australian orchids. Climate change poses a significant threat to biodiversity. Australian sexually deceptive orchids are dependent on obligate and specialised interactions with pollinators and fungi. Consequently, they may face a high risk of extinction if climate change uncouples these interactions. Thus orchids provide an important bio-indicator of change. The tools and expertis ....A multidisciplinary research program to assess limiting factors and predict impacts of climate change for endangered Australian orchids. Climate change poses a significant threat to biodiversity. Australian sexually deceptive orchids are dependent on obligate and specialised interactions with pollinators and fungi. Consequently, they may face a high risk of extinction if climate change uncouples these interactions. Thus orchids provide an important bio-indicator of change. The tools and expertise developed will contribute directly to the conservation of endangered Australian orchids, and will take into account the risks of climate change. The project will contribute to the priority research goals of sustainable use of Australia's biodiversity as well as responding to climate change and variability. The project will also provide high quality, cross-disciplinary training.Read moreRead less
Understanding “reinforcement”, an evolutionary process that can lead to the origin of new species and generate species diversity. Understanding how species are formed is of broad significance. National benefit will come from internationally competitive research and collaborations with leading international researchers.

Understanding how species are formed is of broad significance. National benefit will come from internationally competitive research and collaborations with leading international researchers. Benefits will also come under the ARC Priority Goals of 'An Environmentally Sustainable Australia' as I will (i) provide genetic data that will be invaluable for the conservation of a highly threatened species, (ii) determine the importance of contact zones for generating new species and maintaining the evolutionary potential of regions, and (iii) address the role of climate change in shaping diversity over recent evolutionary time, an understanding of which is essential for predicting the impact of future change.

Molecular Phylogenetics of Australian Myobatrachid Frogs and the Evolution of Reproductive Strategies. The Family Myobatrachidae (22 genera, 120+ species) is wholly endemic to the Australo-Papuan region, represents 57% of the Australian frog fauna and displays more diversity in reproductive strategies than any other group of frogs. We will recover a robust molecular phylogeny for all species in this family and use it to exploit existing ecological and behavioural data sets to provide powerful te ....Molecular Phylogenetics of Australian Myobatrachid Frogs and the Evolution of Reproductive Strategies. The Family Myobatrachidae (22 genera, 120+ species) is wholly endemic to the Australo-Papuan region, represents 57% of the Australian frog fauna and displays more diversity in reproductive strategies than any other group of frogs. We will recover a robust molecular phylogeny for all species in this family and use it to exploit existing ecological and behavioural data sets to provide powerful tests of alternative hypotheses concerning the evolution of diverse reproductive strategies. This multi-disciplinary research project will provide detailed phylogenetic information for one of the most diverse vertebrate radiations in Australia and address important questions in historical ecology.Read moreRead less
Structure and function of heterodimeric amino acid transporters. Recently a new family of amino acid transporters has been identified, the members of which are involved in the delivery of amino acids between cells and tissues. All members display a rather unusual structure in that they require two subunits to be functional. The main aim of this study is to investigate the interaction between large and small subunits. The study will give insight how membrane proteins form complexes in the membran ....Structure and function of heterodimeric amino acid transporters.

Life history responses to habitat heterogeneity and implications for conservation. This exciting new research project will provide a novel understanding of how animals respond and adapt to environmental variation. This will fill a critical gap between ecological theory and real-world populations and initiate a major shift in how we view the relationship between environments and the species that inhabit them.

This exciting new research project will provide a novel understanding of how animals respond and adapt to environmental variation. This will fill a critical gap between ecological theory and real-world populations and initiate a major shift in how we view the relationship between environments and the species that inhabit them. Natural resource use practices like forestry are rarely considered compatible with biodiversity conservation. This research will provide on-the-ground management recommendations to integrate such land uses with conservation, thereby providing both economic and conservation benefits to the Australian community.Read moreRead less
