From genes to ecosystems: does genetic divergence in eucalyptus alter biodiversity and ecosystem function? The project will use a dominant tree species of south-eastern Australia to examine how genetic based variation in its traits influences community organisation, biodiversity and ecosystem processes. Outcomes from this research will be important for responding to an uncertain future environment and maintaining the services ecosystems provide.
Evolution, disease and extinction - using ancient and modern Deoxyribonucleic acid (DNA) to investigate molecular evolution in the Tasmanian devil. The Tasmanian devil is Australia's largest living marsupial carnivore and one of Tasmania's key tourism icons. Extinction in the wild will have long-term impacts on Tasmanian native ecosystems and economy. This study will provide critical genetic data and tools to monitor and prioritise conservation strategies, including insurance populations and dis ....Evolution, disease and extinction - using ancient and modern Deoxyribonucleic acid (DNA) to investigate molecular evolution in the Tasmanian devil. The Tasmanian devil is Australia's largest living marsupial carnivore and one of Tasmania's key tourism icons. Extinction in the wild will have long-term impacts on Tasmanian native ecosystems and economy. This study will provide critical genetic data and tools to monitor and prioritise conservation strategies, including insurance populations and disease suppression, aimed at preventing extinction. It will strengthen ongoing conservation programs carried out by the Save the Tasmanian Devil Program and will help publicise the plight of the devil both nationally and internationally.Read moreRead less
Genetic impacts on eucalypt forest biodiversity. Australia is the centre of origin for most of the world's eucalypt genetic resources. This project will provide the research required to develop management strategies to reduce the risk of genetic pollution of this important genetic resource from the expanding eucalypt plantings in Australia. It will provide leading-edge science to better assess the risk and impact of genetic pollution not only on the native eucalypt gene pools per se but also on ....Genetic impacts on eucalypt forest biodiversity.

It will provide leading-edge science to better assess the risk and impact of genetic pollution not only on the native eucalypt gene pools per se but also on the structure and biodiversity of the fungi, insect and vertebrate communities that are dependent on the eucalyptsRead moreRead less
Genetic legacy of climate change in Australian temperate forests. This work will make a significant contribution to the understanding of the Quaternary history of the forests of south-eastern Australia. Finding the location of glacial refugia is crucial to the development of long-term conservation strategies, as they are areas of high genetic and species diversity. Understanding the evolutionary processes that affect genetic diversity and gene flow of these keystone species (Nothofagus cunningha ....Genetic legacy of climate change in Australian temperate forests. This work will make a significant contribution to the understanding of the Quaternary history of the forests of south-eastern Australia. Finding the location of glacial refugia is crucial to the development of long-term conservation strategies, as they are areas of high genetic and species diversity. Understanding the evolutionary processes that affect genetic diversity and gene flow of these keystone species (Nothofagus cunninghamii, N. moorei, Acacia melanoxylon, Eucalyptus viminalis) will help their long-term management.Read moreRead less
Contribution of hybridisation to genetic diversity and adaptation in Eucalyptus. The eucalypt gene pool is an outstandingly important bioresource for Australia. Its effective future management will be based on understanding the extent, causes and significance of genetic variation in eucalypt species. This project investigates a currently overlooked, but potentially important, source of genetic diversity and adaptation in Eucalyptus. The knowledge gained will contribute substantially to our un ....Contribution of hybridisation to genetic diversity and adaptation in Eucalyptus. The eucalypt gene pool is an outstandingly important bioresource for Australia. Its effective future management will be based on understanding the extent, causes and significance of genetic variation in eucalypt species. This project investigates a currently overlooked, but potentially important, source of genetic diversity and adaptation in Eucalyptus. The knowledge gained will contribute substantially to our understanding of eucalypt biology, and will inform decision-making for conservation, revegetation, and sustainable use of seed resources. Through addressing fundamental questions, the project will also provide a uniquely Australian contribution to world research in forest molecular genetics.Read moreRead less
The role of recombination in eucalypt evolution. Meiotic recombination is a key source of the genetic variation upon which evolution thrives. This project aims to exploit new genomic resources to provide the first detailed study of recombination in Australia’s iconic Eucalypts and clarify its evolutionary role. This project will study: variation in the rate of recombination along the 11 Eucalypt chromosomes, and determine genome features which are associated with ‘hotspots’ and ‘coldspots’ of re ....The role of recombination in eucalypt evolution. Meiotic recombination is a key source of the genetic variation upon which evolution thrives. This project aims to exploit new genomic resources to provide the first detailed study of recombination in Australia’s iconic Eucalypts and clarify its evolutionary role. This project will study: variation in the rate of recombination along the 11 Eucalypt chromosomes, and determine genome features which are associated with ‘hotspots’ and ‘coldspots’ of recombination; the patterns of variation in recombination rate between species, genotypes, sexes and chromosomes; and, whether the environment and population history affect recombination and thus evolvability of natural populations.Read moreRead less
Genetics of species differentiation and hybridisation in Eucalyptus. This project aims to use state-of-the-art genomic technologies to characterise genes and genomic regions important for speciation and adaptation in Australia’s iconic eucalypts, and study the importance of hybridisation between species, especially during range expansion and contraction. A major international effort has seen a eucalypt become the second forest tree genome sequenced. This project aims to link the expanding intern ....Genetics of species differentiation and hybridisation in Eucalyptus. This project aims to use state-of-the-art genomic technologies to characterise genes and genomic regions important for speciation and adaptation in Australia’s iconic eucalypts, and study the importance of hybridisation between species, especially during range expansion and contraction. A major international effort has seen a eucalypt become the second forest tree genome sequenced. This project aims to link the expanding international knowledge on the eucalypt genome to the evolutionary dynamics of wild populations in Australia to provide unprecedented insights into the nature of species and processes which have shaped their evolution. These insights may inform their breeding as well as their conservation and management in Australia.Read moreRead less
Genetics of species differentiation and hybridisation in Eucalyptus. Eucalypts are an icon of Australia and of great economic and ecological significance. This project will use genomic technologies to provide novel insights into the evolutionary processes that shape diversity in this genus. This will contribute to the development of better conservation and management practices for this valuable genetic resource.
The genetics of adaptation: changing developmental trajectories in eucalypts. During their life cycles, many animals and plants undergo genetically programmed changes in form. Such changes may be dramatic and rapid as seen in insect metamorphoses or plant heteroblasty, and may have ecological, evolutionary and even economic consequences. The project aims to identify the genes controlling such transitions in Australia's eucalypts.
