New phylogenetic approaches for understanding evolution at the genome scale. This project aims to use genome data to improve our understanding of the evolutionary process, including the forces that shape evolution on a whole-genome scale. The project plans to create a curated database of genome sequences and a comprehensive framework for evolutionary analyses of genomes.

This project aims to use genome data to improve our understanding of the evolutionary process, including the forces that shape evolution on a whole-genome scale. The project plans to create a curated database of genome sequences and a comprehensive framework for evolutionary analyses of genomes. The new approach is designed to be used to analyse patterns of evolutionary rate variation to identify the key features of genome evolution. In addition, the development of a genome-scale approach to molecular dating will improve estimates of the timescale of the Tree of Life. This project is expected to yield useful insights into molecular evolution and to provide a valuable guide for future evolutionary analyses of genomes.Read moreRead less

This project aims to identify, understand, and characterise patterns of evolutionary rates across different levels of biological variation. The project expects to generate knowledge about the tempo and mode of evolution by using a phylogenetic approach to test fundamental models of evolutionary rates, including the link between rates of genomic and morphological evolution. Expected outcomes of this project include detailed insights into the tempo and mode of macroevolution, better modelling of genomic and phenotypic evolution, and improved design of studies in evolutionary genomics. Benefits of the project include greater understanding of the evolutionary processes that have generated the diversity of the Australian biota.Read moreRead less
Directed evolution of ancestral bacterial flagellar motors. This project aims to produce new knowledge concerning the adaptation of bacterial species to wide environmental changes. The bacterial flagellar motor (BFM) is a motor 40 nanometers in diameter that builds itself into bacterial membranes, rotates five times faster than a Formula One engine, and switches directions in milliseconds. . This project will combine ancestral reconstruction of ancient motor components with protein engineering t ....Directed evolution of ancestral bacterial flagellar motors. This project aims to produce new knowledge concerning the adaptation of bacterial species to wide environmental changes. The bacterial flagellar motor (BFM) is a motor 40 nanometers in diameter that builds itself into bacterial membranes, rotates five times faster than a Formula One engine, and switches directions in milliseconds. . This project will combine ancestral reconstruction of ancient motor components with protein engineering to understand how the different ion channels that power the BFM in different species are selective for different positive ions. It will inspire and inform future manufacturing in bionanotechnology.Read moreRead less
Estimating evolutionary time-scales using genomic sequence data: exploiting opportunities and meeting challenges. Genomic data are being produced at a phenomenal rate, enabling detailed investigations of various biological questions. This project will exploit the new opportunities for improving the estimation of evolutionary time-scales, and develop methods and software to address the new challenges that have surfaced.
Improving access to phylogenomic resources for under-resourced species: a new look at existing tools. This project will have an impact on our understanding of how to most effectively use existing genomic resources to benefit a wider range of species and to better design new genomic resources. By doing so, improved access to genomic resources will be provided to species that currently have few options.
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 will also provide an ....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 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
Conservation genetics of the Endangered Oxleyan Pygmy Perch Nannoperca oxleyana. The aim of this study is to determine how isolation of populations of the endangered Oxleyan Pygmy Perch Nannoperca Oxleyana affects their genetic composition. The significance of the study is that it will enhance our ability to conserve the species, and enhance our understanding of the genetics of isolated populations of freshwater fish generally.
Can lateral gene transfer lead to ecological innovation in eukaryotes? The role of saxitoxin in the diversification of Alexandrium. This project will determine the processes that led to the acquisition and diversification of the genetic basis for a potent neurotoxin, saxitoxin. This project will determine its impact on the evolution of the marine producing organisms and investigate novel genetic methods of toxin detection.
