This research is focussed at the highest level in the field of evolutionary biology; testing recent theory for the evolution of alternative reproductive tactics and using these species to test hypotheses about adaptation. The proposal involves collaborations with high-profile researchers from three European countries and will increase Australia's standing as a world-leader in evolutionary biology. Australian students will benefit from exposure to high quality international collaborators. We will also increase our understanding of the biology of the European earwig, a pest species in Australia. Reproductive tactics are exciting topics for media attention and this research will reach a wide and interested Australian and world audience.Read moreRead less
Quantifying condition-dependence in sexual selection. This research centres on testing evolutionary models of sexual selection. The project has relevance for understanding the role of mutations in reducing the fitness of populations and hence has implications for the conservation of endangered species and for human health. The research also investigates how investment in one trait, such as horns, will take resources away from another, like muscle. This has implications for animal production. The ....Quantifying condition-dependence in sexual selection. This research centres on testing evolutionary models of sexual selection. The project has relevance for understanding the role of mutations in reducing the fitness of populations and hence has implications for the conservation of endangered species and for human health. The research also investigates how investment in one trait, such as horns, will take resources away from another, like muscle. This has implications for animal production. The project utilises pest species as research models and will hence provide further understanding of pest life-history, knowledge critical to the success of control programmes. Australian science will further benefit through the research fellow's established collaborations with international scientists.Read moreRead less
Establishment of the Australian Cane Toad Genome Program. The Cane Toad is one of Australia's greatest environmental menaces, and is in the top 100 of the "World's Worst invader species". Over a billion toads infest Northern Australia, and they will soon invade WA and move further into NSW. Their poisons and voracious appetite could make many native mammals, birds and reptiles extinct. The only possibility to eradicate the Toad is by biological control, but there is no known control agent. We wi ....Establishment of the Australian Cane Toad Genome Program. The Cane Toad is one of Australia's greatest environmental menaces, and is in the top 100 of the "World's Worst invader species". Over a billion toads infest Northern Australia, and they will soon invade WA and move further into NSW. Their poisons and voracious appetite could make many native mammals, birds and reptiles extinct. The only possibility to eradicate the Toad is by biological control, but there is no known control agent. We will identify the 'Toad's Achilles' heel' against which control agents can be developed. We can do this by identifying every Toad gene. This project forms the first step to this goal by establishing the Australian Cane Toad Genome Program. Toad control will help preserve Australia's unique natural heritage.Read moreRead less
Early evolutionary origins of mechanosensory transduction: structure, function and phylogenetic studies of the family of mechanosensitive channels in cell-walled organisms. The proposed project is based on the recent progress the applicants have made by (i) identifying a novel family of mechanosensitive (MS) channels in cell-walled organisms, which include Archaea and Bacteria (prokaryotes), as well as fungi and plants (eukaryotes), and (ii) determining basic aspects of the structural dynamics ....Early evolutionary origins of mechanosensory transduction: structure, function and phylogenetic studies of the family of mechanosensitive channels in cell-walled organisms. The proposed project is based on the recent progress the applicants have made by (i) identifying a novel family of mechanosensitive (MS) channels in cell-walled organisms, which include Archaea and Bacteria (prokaryotes), as well as fungi and plants (eukaryotes), and (ii) determining basic aspects of the structural dynamics of MscL, the prototype MS channel, using electronparamagnetic resonance spectroscopy and molecular dynamics simulations in combination with the patch clamp technique. The aim of the project is to elucidate the molecular principles underlying the function of MS channels, which is of fundamental importance for understanding of the biophysics and physiology of mechanosensory transduction throughout the biological world.Read moreRead less

The proposed research will significantly contribute to a better understanding of the wide range of physiological processes underlying mechanosensory transduction in living cells. The direct benefit for Australian science consists of: (i) strengthening international links with leading overseas laboratories, and (ii) accessing the state-of-the-art expertise not available in Australia. The acquired knowledge will aid in developing and designing artificial tactile sensors inspired by their biological models studied in this project. Long-term, the project is expected to make an original contribution towards developing new technologies and novel medical applications, both of which promise to be of great national benefit.Read moreRead less

We will provide important methodological and analytical advances at the cutting edge of physiological research. This project will sustain our leading role as marsupial physiologists in the international scientific community, contribute to the high-quality training of research students, foster national and international collaboration, and generally enhance the scientific profile of Australia. Knowledge of a species' biology and its interactions with the environment are essential for conservation in the face of landscape modification and climate change.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.

Computational Molecular Science (CMS) involves the use of theory and computational methods to simulate and visualise molecular systems ranging from small atmospheric species to proteins, nucleic acids, chemical polymers and materials. It represents our most incisive expression of what we understand about the molecular basis of nature. The CMS network will integrate and cross-fertilize both fundamental and application-based expertize in molecular scale computations in the fields of nanoscience, biomaterials, biotechnology, biomedical science and environmental science. It will uncover and explore critical new interdisciplinary science and create new molecular-based paradigms that will drive advances in these fields over the next decade.Read moreRead less
Sperm Competition and Sexual Selection. Competition between the sperm of two males within a single female has had profound implications for the evolution of male reproductive biology and behaviour. However, the reasons why females should mate with more than one male and thus generate sperm competition remains an evolutionary puzzle. Few studies have examined sperm competition from the female perspective and indeed, female perspectives are currently the subject of considerable debate. Using in ....Sperm Competition and Sexual Selection. Competition between the sperm of two males within a single female has had profound implications for the evolution of male reproductive biology and behaviour. However, the reasons why females should mate with more than one male and thus generate sperm competition remains an evolutionary puzzle. Few studies have examined sperm competition from the female perspective and indeed, female perspectives are currently the subject of considerable debate. Using insects as models I will examine the benefits of sperm competition for females and thereby the selective pressures that favour multiple mating. Moreover, I will determine whether sexual selection can act after copulation.Read moreRead less

Marsupial genomes are uniquely valuable because they provide comparisons that reveal new human genes, regulatory sequences and marsupial-specific genes. These will deliver new products and information useful for medicine, industry, agriculture and conservation. We will construct integrated genetic and physical maps of the genome, clone the whole genome as large inserts in BAC vectors, and build a "golden path" with minimal overlap. We will construct libraries of expressed genes from tammar tissues and array them for use in analysing gene expression.Read moreRead less
