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
Testing links between genomic and morphological evolutionary rates. 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 insig ....Testing links between genomic and morphological evolutionary rates. 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
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
The evolution of multipartite mitochondrial genomes in the cyst-forming nematodes. The cyst-forming nematodes are a serious pest of agricultural crops throughout the world, attacking cereal, root and legume crops. Although sporadically recorded in Australia, they have not become established here. This project will characterize unique sequences from the noncoding portion of the mitochondrial genome of a range of cyst-forming nematodes, facilitating the development of molecular diagnostic screen ....The evolution of multipartite mitochondrial genomes in the cyst-forming nematodes. The cyst-forming nematodes are a serious pest of agricultural crops throughout the world, attacking cereal, root and legume crops. Although sporadically recorded in Australia, they have not become established here. This project will characterize unique sequences from the noncoding portion of the mitochondrial genome of a range of cyst-forming nematodes, facilitating the development of molecular diagnostic screening tools for these crop pests. This program will train a number of young scientists with skills in biotechnology, preparing them to join programs safeguarding our agricultural industries.Read moreRead less
