Fish venom as a model system for the molecular evolution of defensive toxins. The key aim of this study is to undertake a thorough investigation of venoms found in distinct fish lineages, including enigmatic species such as venomous and medically important species such as the stonefish. By characterising the biodiversity of toxins found in the venoms of different fish, the evolutionary history of venom in this major vertebrate lineage can be revealed. The investigations proposed here will also d ....Fish venom as a model system for the molecular evolution of defensive toxins. The key aim of this study is to undertake a thorough investigation of venoms found in distinct fish lineages, including enigmatic species such as venomous and medically important species such as the stonefish. By characterising the biodiversity of toxins found in the venoms of different fish, the evolutionary history of venom in this major vertebrate lineage can be revealed. The investigations proposed here will also determine the functional activities of different venoms and their components. This will not only help the understanding of the medical consequences of the annual thousands of fish envenomings but also explore a largely unstudied resource for the discovery of new pharmacological diagnostics and therapeutics.Read moreRead less
Evolutionary venomics: Venom system diversification in the animal kingdom. This proposal represents a tremendous opportunity for biodiscovery from the Australian toxic fauna. This will be achieved through the researcher's unique approach of investigating previously unmapped venom systems for divergent, bioactive proteins.

Molecular evolution and toxinology of colubrid snake venom toxins. This project proposes to examine the origin and evolution of venom systems in advanced snakes (Caenophidia) focusing on the colubrid radiation comprising the rear-fanged species. Demonstration by us of the presence of a potent postsynaptic neurotoxin in the Durvenoy's secretions of the Asian ratsnake Elaphe radiata, an archetypal non-venomous colubrid species, forced a fundamental rethink of venom evolution. The toxin is homologo ....Molecular evolution and toxinology of colubrid snake venom toxins. This project proposes to examine the origin and evolution of venom systems in advanced snakes (Caenophidia) focusing on the colubrid radiation comprising the rear-fanged species. Demonstration by us of the presence of a potent postsynaptic neurotoxin in the Durvenoy's secretions of the Asian ratsnake Elaphe radiata, an archetypal non-venomous colubrid species, forced a fundamental rethink of venom evolution. The toxin is homologous with the three finger toxins, previously thought unique to elapids, and supports the role of venom as a key evolutionary innovation in the diversification of advanced snakes. This project extends this work to other species and toxin families.Read moreRead less
Dynamics and correlations of many-body systems. The proposed program will greatly enhance Australian science through linking innovative
theoretical techniques with the successful ongoing Australian experimental program in atom
lasers, atom chip interferometry and ultra-cold fermions. Pioneering theoretical methods in
quantum phase-space are internationally recognized, and will be extended into new areas relevant

theoretical techniques with the successful ongoing Australian experimental program in atom
lasers, atom chip interferometry and ultra-cold fermions. Pioneering theoretical methods in
quantum phase-space are internationally recognized, and will be extended into new areas relevant
to Australia. These have fundamental significance to fields ranging from nanotechnology to
astrophysics, as well as providing a route to improved atomic clocks and other instruments.
Combining these theoretical and computational methods from the physical sciences with biology
and genetics will provide future cross-disciplinary benefits to Australian biomedical science.Read moreRead less
Recombination of mitochondrial genomes: what can we learn from chigger mites? This project will bring three benefits to Australia. First, it will enhance Australia's research capacity in the fields of organelle genomics and evolutionary biology. Second, it will yield highly skilled young researchers: a postdoctoral fellow (Shao), a PhD student and two BSc Honours students. Third, it will generate new knowledge about genome recombination in animal mitochondria. Recombination is a fundamental, yet ....Recombination of mitochondrial genomes: what can we learn from chigger mites? This project will bring three benefits to Australia. First, it will enhance Australia's research capacity in the fields of organelle genomics and evolutionary biology. Second, it will yield highly skilled young researchers: a postdoctoral fellow (Shao), a PhD student and two BSc Honours students. Third, it will generate new knowledge about genome recombination in animal mitochondria. Recombination is a fundamental, yet poorly understood issue in mitochondrial genomics and evolutionary biology. Knowledge from this project will also improve our understanding of other important issues that are associated with animal mitochondria; like the mechanisms of mitochondrial disease and ageing, and the evolution of modern humans and other animals.Read moreRead less
Monotreme immune system provides insights into their evolutionary relationships. Genes of immunological importance will be cloned and characterised from the short-beaked echidna with the purpose of investigating the immune system in monotremes, gaining insights into the timing and order of evolutionary separation of the three extant mammalian groups:- the Prototherians (monotremes), the Metatherians (marsupials) and Eutherians (placentals), increasing understanding of the evolution of the verteb ....Monotreme immune system provides insights into their evolutionary relationships.

Movement patterns and habitat utilisation of the endangered eastern freshwater cod, Maccullochella ikei Rowland. The project aims to quantify the movement patterns and habitat utilisation of the endangered eastern freshwater cod (Maccullochella ikei) at a larval, juvenile, adult and historical level. Most previous studies regarding the life-history of fish species have failed to adopt this holistic approach, with management often based on fragmented information.

The project aims to quantify the movement patterns and habitat utilisation of the endangered eastern freshwater cod (Maccullochella ikei) at a larval, juvenile, adult and historical level. Most previous studies regarding the life-history of fish species have failed to adopt this holistic approach, with management often based on fragmented information. The project will also provide an insight into the biology of one of the most poorly understood coastal stream fishes of eastern-Australia and assist in ensuring the conservation of this endangered species, and offer a framework from which future studies into the life history of freshwater fish species worldwide can be based.Read moreRead less
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.
