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
Coevolution of sundew bugs and sundews. This project aims to conduct a study of insect-plant interactions to determine if insects and plants coevolve or if they diversify by other evolutionary processes. Insect-plant coevolution is a hotly contested field in evolutionary biology. In Australia, a remarkable interaction exists between carnivorous plants and a group of bugs that steal the plant’s prey. This system offers a great opportunity to test competing coevolutionary theories through a combin ....Coevolution of sundew bugs and sundews. This project aims to conduct a study of insect-plant interactions to determine if insects and plants coevolve or if they diversify by other evolutionary processes. Insect-plant coevolution is a hotly contested field in evolutionary biology. In Australia, a remarkable interaction exists between carnivorous plants and a group of bugs that steal the plant’s prey. This system offers a great opportunity to test competing coevolutionary theories through a combination of historical and ecological approaches. The project expects to showcase the evolution and uniqueness of Australia’s native biota.Read moreRead less
Design of the cardiovascular system of living and fossil vertebrates. This project aims to understand how the heart and blood vessels evolved in mammals, birds, reptiles and fish to achieve efficiency. The heart is the most important organ for life. The project will study the structure and function of vertebrate animals’ hollow and spongy hearts to show how energetics shaped their evolution. It will measure arterial holes in bone to gauge brain and bone metabolism, which opens up a new way to me ....Design of the cardiovascular system of living and fossil vertebrates. This project aims to understand how the heart and blood vessels evolved in mammals, birds, reptiles and fish to achieve efficiency. The heart is the most important organ for life. The project will study the structure and function of vertebrate animals’ hollow and spongy hearts to show how energetics shaped their evolution. It will measure arterial holes in bone to gauge brain and bone metabolism, which opens up a new way to measure metabolism in extinct animals directly from fossils, rather than by inference from living relatives. The expected outcome is to correlate cardiovascular design and metabolic rates of organs.Read moreRead less
Reconstructing the human colonisation of the Pacific using modern and ancient chicken DNA. We will reconstruct one of the last great human migrations, from Island Southeast Asia across the Pacific to Hawaii and Easter Island, using DNA from the domestic chicken, which was carried on the voyage. Ancient and modern DNA, and archaeological data will be used to reveal the source, route, timing, and whether contact was made with South America
Diet influences the selective advantage of mitochondrial DNA mutations. This project aims to examine critical mechanisms that affect mitochondrial DNA variation within species. It aims to test the hypothesis that mitochondrial DNA haplotypes have the potential to be under nutritionally induced balancing selection as a consequence of cellular signalling and/or Adenosine triphosphate (ATP) production by mitochondria. Diet can vary both seasonally and geographically and is a key environmental param ....Diet influences the selective advantage of mitochondrial DNA mutations. This project aims to examine critical mechanisms that affect mitochondrial DNA variation within species. It aims to test the hypothesis that mitochondrial DNA haplotypes have the potential to be under nutritionally induced balancing selection as a consequence of cellular signalling and/or Adenosine triphosphate (ATP) production by mitochondria. Diet can vary both seasonally and geographically and is a key environmental parameter that influences the ability of a species to colonise new habitats. The project plans to characterise the functional links between specific mitochondrial DNA haplotypes, mitochondrial functions and organismal traits. The expected outcome is a more precise grasp of the processes influencing genetic variation within and among species, which would inform current issues in ecology and genetics.Read moreRead less
Refining the timescale of human evolution and dispersal using ancient DNA. Understanding the timescale of human evolution and migration is a key goal of genetic analysis. It provides the foundation for studying our evolutionary and demographic history, our relationships to other hominids and our impact on the natural world. This project aims to use ancient DNA data to improve estimates of our evolutionary timescale.
Protecting cereal grain development at high temperatures. This project aims to investigate new temperature-responsive factors that regulate cereal grain development to protect grain production under heat stress. The new research will leverage international collaborations with access to cutting-edge genetic and technological resources, and refine novel X-ray imaging techniques in Australia, to observe how temperature affects flower structure and function in barley and rice. Favourable mutations t ....Protecting cereal grain development at high temperatures. This project aims to investigate new temperature-responsive factors that regulate cereal grain development to protect grain production under heat stress. The new research will leverage international collaborations with access to cutting-edge genetic and technological resources, and refine novel X-ray imaging techniques in Australia, to observe how temperature affects flower structure and function in barley and rice. Favourable mutations that optimise plant yield and fitness will be defined and explored in other, more complex, cereals such as wheat. Expected outcomes will be fundamental breakthroughs in understanding how plants respond to, and buffer, the effects of heat to lead to translational breeding strategies that bolster grain yield.Read moreRead less

Rediscovering Aboriginal dispersal pathways. This project aims to use cutting-edge and transdisciplinary tools in partnership with Aboriginal people to rediscover deliberate prehistoric plant dispersal pathways along the Australian east coast. By working on three unrelated species with similar disjunct distributions, expected outcomes include detecting significant ‘cultural’ vegetation patterns that will challenge current assumptions about 'natural' plant distributions. New associations between ....Rediscovering Aboriginal dispersal pathways. This project aims to use cutting-edge and transdisciplinary tools in partnership with Aboriginal people to rediscover deliberate prehistoric plant dispersal pathways along the Australian east coast. By working on three unrelated species with similar disjunct distributions, expected outcomes include detecting significant ‘cultural’ vegetation patterns that will challenge current assumptions about 'natural' plant distributions. New associations between plant biogeography and deliberate Aboriginal manipulation of Australian environments will benefit cultural heritage, land management and restoration initiatives.Read moreRead less
