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
Additive and non-additive genetic benefits of mating behaviour: a synthesis of sexual selection and conservation genetics. This research will forge a synthesis between the study of mating behaviour and it's consequences (sexual selection) and the field of conservation genetics. It will have direct relevance to conservation attempts, and far-reaching implications for how we understand sexual behaviour and the complex mating decisions animals and humans make. The work will enhance Australia's stro ....Additive and non-additive genetic benefits of mating behaviour: a synthesis of sexual selection and conservation genetics.

The Genetic Basis of Differences Between the Sexes. Improved medical interventions against genetic disorders like cancer are made possible by advances in fundamental understanding of gene function and, especially, genetic mechanisms (like genomic imprinting) that are directly implicated in these disorders. Furthermore, an understanding of environmental effects within and across generations is vital in an age of global climate change. Recent theory and evidence suggest that research on sexually d ....The Genetic Basis of Differences Between the Sexes. Improved medical interventions against genetic disorders like cancer are made possible by advances in fundamental understanding of gene function and, especially, genetic mechanisms (like genomic imprinting) that are directly implicated in these disorders. Furthermore, an understanding of environmental effects within and across generations is vital in an age of global climate change. Recent theory and evidence suggest that research on sexually dimorphic traits may hold a key to a better understanding of these phenomena. The proposed research will strengthen Australia's position as leader in evolutionary genetics, enhance knowledge of native fauna, and improve our understanding of biological phenomena that affect human health.

Defining unconscious and artificial selection. In 1868 Charles Darwin proposed that the process of domestication can be divided into two independent selective processes we now call unconscious and artificial selection. In this project, we include the Australian dingo as a functional intermediate between the wild wolf and domestic dogs and test Darwin's hypothesis using modern molecular and statistical techniques. It is now widely accepted that the dingo was not domesticated by indigenous Austral ....Defining unconscious and artificial selection. In 1868 Charles Darwin proposed that the process of domestication can be divided into two independent selective processes we now call unconscious and artificial selection. In this project, we include the Australian dingo as a functional intermediate between the wild wolf and domestic dogs and test Darwin's hypothesis using modern molecular and statistical techniques. It is now widely accepted that the dingo was not domesticated by indigenous Australians and is therefore the ideal extant population for the project. The project is significant because it will be a critical test of Darwin's hypothesis. The outcome could be an improved understanding of the genomic basis for selection that can inform the process of domestication.Read moreRead less
The Epigenetics of Sex in the Dragon. Genetic codes do not directly translate to phenotypes -- environment acts through epigenetics to modify development. We use advanced molecular techniques to examine how epigenetics responds to temperature to reverse sex in our novel animal model, the dragon lizard. How does the cell sense temperature? Once the extrinsic signal is captured, how does it influence chromatin modification to release or suppress key genes in the sex differentiation pathway? Which ....The Epigenetics of Sex in the Dragon. Genetic codes do not directly translate to phenotypes -- environment acts through epigenetics to modify development. We use advanced molecular techniques to examine how epigenetics responds to temperature to reverse sex in our novel animal model, the dragon lizard. How does the cell sense temperature? Once the extrinsic signal is captured, how does it influence chromatin modification to release or suppress key genes in the sex differentiation pathway? Which sex genes are targets? Epigenetic enzymes are astonishingly conserved, providing exciting opportunities to draw from human systems to unravel novel signatures of temperature-induced sex switching in reptiles. This project will advance knowledge of developmental programming generally.Read moreRead less
The roles of relatedness and reproductive success in complex social systems of dolphins. Theories of the role of genetic relatedness and reproductive success in mammalian social behaviour have mostly been restricted to primates and carnivores. Coexisting alternative strategies within one population of bottlenose dolphins (Shark Bay WA) offer unprecedented opportunities for such investigations. The male alliances? complexity is unparalleled outside humans, and may require new theory. Some femal ....The roles of relatedness and reproductive success in complex social systems of dolphins. Theories of the role of genetic relatedness and reproductive success in mammalian social behaviour have mostly been restricted to primates and carnivores. Coexisting alternative strategies within one population of bottlenose dolphins (Shark Bay WA) offer unprecedented opportunities for such investigations. The male alliances? complexity is unparalleled outside humans, and may require new theory. Some female lineages show tool-use - rare outside humans, and virtually unknown in marine species. Our behavioural and genetic database has exceptional size, detail and duration for marine mammals, and is most valuable if continued while known individuals' offspring reach a stage where they can be sampled.Read moreRead less
Fire, bees and other disturbances: the basis for variation in genetic diversity in long-lived plants. An understanding of processes generating temporal and spatial patterns of genetic diversity in perennial plants must underpin successful conservation. Our long-term study will exploit systems in the family Proteaceae in which we have completed foundation studies. We will develop and extend molecular techniques to measure (i) genetic changes from seed to adult, (ii) gene flow by different pollina ....Fire, bees and other disturbances: the basis for variation in genetic diversity in long-lived plants. An understanding of processes generating temporal and spatial patterns of genetic diversity in perennial plants must underpin successful conservation. Our long-term study will exploit systems in the family Proteaceae in which we have completed foundation studies. We will develop and extend molecular techniques to measure (i) genetic changes from seed to adult, (ii) gene flow by different pollinator classes, and (iii) genetic contamination by foreign gene pools, in systems affected by introduced pollinators and natural and cultivar hybridization. Most importantly, we will use fire as an accelerant of generational change and test fitness consequences of changes in genotypic diversity.Read moreRead less
