The Origin and Evolution of the Animal Phyla inferred from Analysis of Multiple-Gene Data. Australia has recently begun an extensive research programme in the genomics of our flora and fauna. The enormous amounts of data that emerge from such research are highly complex, but they hold the key to understanding how biological organisms change over time. Our research will untangle that data to answer fundamental, unanswered questions in modern science: How did the animal groups originate?

Australia has recently begun an extensive research programme in the genomics of our flora and fauna. The enormous amounts of data that emerge from such research are highly complex, but they hold the key to understanding how biological organisms change over time. Our research will untangle that data to answer fundamental, unanswered questions in modern science: How did the animal groups originate? How are they related to each other? How is biodiversity changing? The answers to these questions and the new analytical tools we will develop will put Australia firmly on the international "map" of Bioinformatics.Read moreRead less
Structural reorganization of the hymenopteran mitochondrial genome. This study will be the first detailed investigation of the evolution of mt genome reorganization, and as such it will identify the processes that shape the evolution of a molecule widely used to interpret phylogeny. A description of the processes that lead to mt genome reorganization will have a substantial impact on our understanding in two areas of mt biology; (1) the discovery of new molecular phenomena that impact on the or ....Structural reorganization of the hymenopteran mitochondrial genome. This study will be the first detailed investigation of the evolution of mt genome reorganization, and as such it will identify the processes that shape the evolution of a molecule widely used to interpret phylogeny. A description of the processes that lead to mt genome reorganization will have a substantial impact on our understanding in two areas of mt biology; (1) the discovery of new molecular phenomena that impact on the organization and evolution of this genome, and (2) the interpretation of its phylogenetic content. It will establish our research group as a leader in the field of evolutionary genetics. Training of high quality students, with exposure to international researchers, will be a significant component of this program.Read moreRead less

Analysing and modelling molecular rate variation among nuclear and mitochondrial genomes. My research will have important practical benefits for bioinformaticians and evolutionary biologists, because existing analytical methods will be rigorously tested and new tools will be developed. Australia has a comparatively high concentration of researchers in this field, so my research will foster domestic collaboration and import international expertise.

My research will have important practical benefits for bioinformaticians and evolutionary biologists, because existing analytical methods will be rigorously tested and new tools will be developed. Australia has a comparatively high concentration of researchers in this field, so my research will foster domestic collaboration and import international expertise. The research will provide important insights into the rates and patterns of genetic changes associated with domestication, and into variation in evolutionary rates among the primate ancestors of humans. In addition to developing new software, which will be made publicly available, I will develop new evolutionary models to supplement existing software packages. Read moreRead less
Molecular identification of blowflies of forensic importance and thermal effects on their behaviour: tools to enhance forensic entomology in Australia. In suspicious deaths in which a body is found three or more days post-mortem, carrion-breeding blowflies provide time since death estimates. These estimates are currently slow and relatively broad due to (a) an inability to adequately distinguish immatures morphologically, and (b) insufficient information on the biological responses of different ....Molecular identification of blowflies of forensic importance and thermal effects on their behaviour: tools to enhance forensic entomology in Australia. In suspicious deaths in which a body is found three or more days post-mortem, carrion-breeding blowflies provide time since death estimates. These estimates are currently slow and relatively broad due to (a) an inability to adequately distinguish immatures morphologically, and (b) insufficient information on the biological responses of different species to temperature. We will develop rapid molecular assays to distinguish blowfly species, and comprehensively chart the behavioural effects of temperature on the most forensically important blowflies. Molecular and adult morphological data will also be used to examine the evolution of the carrion-breeding blowflies.Read moreRead less
Quantum Dot Nanocrystals: Smart Materials for Microbiology. Quantum dots were originally developed for computers but have many advantages over fluorescent dyes currently in use. They can be coupled to larger structures and a excitation with a laser allows simultaneous multiple analyses ("multiplexing"). We propose to adapt these structures for use in microbial ecology because this field is one of the least understood areas in biology. The technology we will develop will have far broader uses, a ....Quantum Dot Nanocrystals: Smart Materials for Microbiology. Quantum dots were originally developed for computers but have many advantages over fluorescent dyes currently in use. They can be coupled to larger structures and a excitation with a laser allows simultaneous multiple analyses ("multiplexing"). We propose to adapt these structures for use in microbial ecology because this field is one of the least understood areas in biology. The technology we will develop will have far broader uses, and will create new diagnostic tools for monitoring and understanding microbial ecosystems would be invaluable in a number of fields. Examples are medical diagnostics, waste-water treatment, bioremediation, food and agriculture, bioprotection and biodiscovery.Read moreRead less
Retracing the Early Evolution of Metazoa using Novel Methods and Strategies. Metazoa is one of the best-characterised groups of species in terms of its morphology, fossil record, development, and genetic make-up, but the phylogeny remains obscure because the fossil record is incomplete and because molecular phylogenetic methods have not yet been developed with the complexity of genomic data in mind. We will develop methods and strategies for the analysis of whole genomes, and use them in studies ....Retracing the Early Evolution of Metazoa using Novel Methods and Strategies. Metazoa is one of the best-characterised groups of species in terms of its morphology, fossil record, development, and genetic make-up, but the phylogeny remains obscure because the fossil record is incomplete and because molecular phylogenetic methods have not yet been developed with the complexity of genomic data in mind. We will develop methods and strategies for the analysis of whole genomes, and use them in studies of the mitochondrial genome. We will infer the animal phylogeny, and use it to chart the evolution of animal morphology and development, and the evolution of mitochondrial genetic codes, gene order, and nucleotide content.Read moreRead less
Development and implementation of biodiversity information for sustainable management of South Australian groundwater. Clean potable water is one of the most important resources for human health and a successful economy. Increasingly, subterranean aquifers are used for storage and recovery of water. These aquifers contain dynamic ecosystems, but little is known about species composition or about the importance of the presence of various species for water quality. We will use the latest laborator ....Development and implementation of biodiversity information for sustainable management of South Australian groundwater. Clean potable water is one of the most important resources for human health and a successful economy. Increasingly, subterranean aquifers are used for storage and recovery of water. These aquifers contain dynamic ecosystems, but little is known about species composition or about the importance of the presence of various species for water quality. We will use the latest laboratory techniques and DNA identification methods to provide a template for determining ground water diversity and food web dynamics throughout Australia. This project will lead to a better understanding of how to manage ground water in a sustainable manner.Read moreRead less
Signal manipulation in orb-web spiders. A number of diverse orb-web spiders adorn their webs with conspicuous silk bands called decorations or stabilimenta. Their function remains controversial, but they may act as a visual signal to either attract prey, deter predators or prevent web damage by large non-prey animals. We will test these hypotheses on several Australian orb-web species using field and laboratory experiments. Furthermore, we will investigate the effect of web decorations on specie ....Signal manipulation in orb-web spiders. A number of diverse orb-web spiders adorn their webs with conspicuous silk bands called decorations or stabilimenta. Their function remains controversial, but they may act as a visual signal to either attract prey, deter predators or prevent web damage by large non-prey animals. We will test these hypotheses on several Australian orb-web species using field and laboratory experiments. Furthermore, we will investigate the effect of web decorations on species radiation and hence diversity using molecular techniques to establish phylogenies. This will, at least in part, help resolve this century old debate surrounding web decorations.Read moreRead less
The Cambrian Population Explosion of Arthropods in Australia: Ediacaran origins, evolution and biodiversity. This project addresses key questions on the origin and diversification of life, by investigating the evolution of the most important fossil group (arthropods) across arguably the most important event after the origin of life (the Cambrian explosion of macroscopic life). It will also excavate, promote and conserve two key geological resources of national importance, in the Flinders Ranges ....The Cambrian Population Explosion of Arthropods in Australia: Ediacaran origins, evolution and biodiversity. This project addresses key questions on the origin and diversification of life, by investigating the evolution of the most important fossil group (arthropods) across arguably the most important event after the origin of life (the Cambrian explosion of macroscopic life). It will also excavate, promote and conserve two key geological resources of national importance, in the Flinders Ranges and Kangaroo Island. Also, it will lead to increased knowledge of the palaeoecology and geology of the economically-important Adelaide geosyncline, and benefit rural SA communities through ecotourism, a rural schools education program, and public outreach.Read moreRead less
