Summary
Ancient genomics of Western Australian taxa to inform conservation management. The project aims to apply genomic approaches to infer the genetic health and evolutionary history of three threatened, iconic Western Australian taxa: black cockatoos, ghost bats and woylies. Genomic data provide a powerful lens through which to study species, but the applications of genomic techniques in conservation biology have been sparse. Effective restoration and conservation initiatives require an understanding ....Ancient genomics of Western Australian taxa to inform conservation management. The project aims to apply genomic approaches to infer the genetic health and evolutionary history of three threatened, iconic Western Australian taxa: black cockatoos, ghost bats and woylies. Genomic data provide a powerful lens through which to study species, but the applications of genomic techniques in conservation biology have been sparse. Effective restoration and conservation initiatives require an understanding of species' former population sizes, connectivity and biodiversity. The project seeks to elucidate the population genetic, phylogenetic, and conservation genetic parameters of the three species at the genomic level using DNA isolated from modern and ancient sources (eg museum skins and fossils). The information gained may inform conservation efforts for some of Australia’s endangered biota.Read moreRead less
Assessment of past biodiversity through DNA preserved in bulk bone. This project aims to make a unique study of fossils to determine how the composition and biodiversity of ecosystems have changed in response to anthropogenic influences. Fossil bones provide a window through which to study past environments and how they have changed, and the stories these fossils tell can be further enhanced by ancient DNA analyses. This project plans to use bulk bone metabarcoding where hundreds of low-value (f ....Assessment of past biodiversity through DNA preserved in bulk bone. This project aims to make a unique study of fossils to determine how the composition and biodiversity of ecosystems have changed in response to anthropogenic influences. Fossil bones provide a window through which to study past environments and how they have changed, and the stories these fossils tell can be further enhanced by ancient DNA analyses. This project plans to use bulk bone metabarcoding where hundreds of low-value (fragmented) bones are collectively ground together to provide a cost-effective genetic audit of fossil assemblages. Working on bone from across Oceania and south-east Asia, this project aims to provide a historical perspective on biodiversity. Understanding former ecosystem composition and extinction may facilitate effective restoration and conservation initiatives.Read moreRead less
Predicting climate change impacts on biodiversity: testing and applying new approaches. A primary challenge faced by Australia is predicting the threat that climate change will have on biodiversity. This project will dramatically improve our ability to manage threats to biodiversity posed by climate change by studying plant species at warmer latitudes, where they are already experiencing predicted future climate conditions.
Natural selection and the Tasmanian devil. This project aims to explain evolution of immune capabilities in response to disease threats in the wild by assessing the immune adaptive capabilities of Tasmanian devils in response to facial tumour disease. It plans to determine how the expression of immune genes differs between wild and captive populations. The project will combine immunology, epidemiology and evolutionary biology, to understand the role of host genetic and phenotypic adaptations to ....Natural selection and the Tasmanian devil. This project aims to explain evolution of immune capabilities in response to disease threats in the wild by assessing the immune adaptive capabilities of Tasmanian devils in response to facial tumour disease. It plans to determine how the expression of immune genes differs between wild and captive populations. The project will combine immunology, epidemiology and evolutionary biology, to understand the role of host genetic and phenotypic adaptations to disease threats. The project will assist in the development of diagnostic tools for managing this and other threatened species and for screening disease resistance markers across wild and captive insurance populations.Read moreRead less

Summary
Molecular genetic adaptive processes in natural co-evolution between rabbits and the rabbit haemorrhagic disease virus. This project will use extensive sampling and long-term field data to reveal ongoing co-evolutionary mechanisms behind the increasing resistance of pest Australian wild rabbits against a viral pathogen. The results will increase the understanding of evolutionary mechanisms in nature and will provide basic information for biological pest control of rabbits.
Will genetic rescue save the Tasmanian devil? This project aims to measure the long-term genetic impacts of the Save the Tasmanian Devil Program’s ‘Wild Devil Recovery’ initiative. The project will determine whether supplementing small populations with individuals that are genetically diverse reduces inbreeding depression. The project will also monitor the impact of supplementation on the evolutionary trajectory of Devil Facial Tumour Disease. The project will train a cohort of conservation scie ....Will genetic rescue save the Tasmanian devil? This project aims to measure the long-term genetic impacts of the Save the Tasmanian Devil Program’s ‘Wild Devil Recovery’ initiative. The project will determine whether supplementing small populations with individuals that are genetically diverse reduces inbreeding depression. The project will also monitor the impact of supplementation on the evolutionary trajectory of Devil Facial Tumour Disease. The project will train a cohort of conservation scientists to translate genetic data into management actions. The outputs will directly inform the management actions of the Tasmanian Department of Primary Industries Parks, Water and the Environment and will help shape other species recovery programs.Read moreRead less
Evolution in action or the demise of iconic Australian flora? The project aims to investigate the evolutionary history and conservation status of a group of closely related Grevillea species, in the light of increasing pressure from landscape modification. This project will incorporate leading methodologies for massively parallel sequencing, pollinator preference and breeding capacity in order to detect the patterns and processes underpinning divergence in widely distributed species. A phylogene ....Evolution in action or the demise of iconic Australian flora? The project aims to investigate the evolutionary history and conservation status of a group of closely related Grevillea species, in the light of increasing pressure from landscape modification. This project will incorporate leading methodologies for massively parallel sequencing, pollinator preference and breeding capacity in order to detect the patterns and processes underpinning divergence in widely distributed species. A phylogenetic framework will provide the evolutionary relationships among taxa. This project is expected to inform requirements for long-term species persistence and, for threatened species within the group, guide the decision making of biodiversity managers as to what actions are required and where best to invest limited funds.Read moreRead less
Minimising adaptation to captivity for conservation of threatened species. This project aims to determine how evolutionary processes affect the successful release of captive animals. Five years ago the Tasmanian devil was destined for extinction, but scientists now believe they can prevent this. However, they have put all their eggs in one basket – a large captive insurance population which acts as a source for the wild. Adaptation to captivity can have negative consequences for released animals ....Minimising adaptation to captivity for conservation of threatened species. This project aims to determine how evolutionary processes affect the successful release of captive animals. Five years ago the Tasmanian devil was destined for extinction, but scientists now believe they can prevent this. However, they have put all their eggs in one basket – a large captive insurance population which acts as a source for the wild. Adaptation to captivity can have negative consequences for released animals and could threaten the devil programme. Using massive molecular datasets and computational models, this project intends to evaluate different captive breeding scenarios and identify optimal management practices. This will provide environmental policymakers with a new framework for protecting threatened species in Australia and around the world.Read moreRead less
Haplodiploidy: the great evolutionary innovation of the Hymenoptera. This project aims to identify a key gene that causes thelytokous parthenogenesis. Thelytoky is the ability of a female to clone herself (virgin birth), and is wide spread in the Hymenoptera which include bees, wasps and ants. Hymenopteran thelytoky is important because it facilitates some major transitions in life history, particularly social parasitism. The capacity for virgin birth is central to the invasiveness of many ant s ....Haplodiploidy: the great evolutionary innovation of the Hymenoptera. This project aims to identify a key gene that causes thelytokous parthenogenesis. Thelytoky is the ability of a female to clone herself (virgin birth), and is wide spread in the Hymenoptera which include bees, wasps and ants. Hymenopteran thelytoky is important because it facilitates some major transitions in life history, particularly social parasitism. The capacity for virgin birth is central to the invasiveness of many ant species, and enables social cancers (parasitic workers that kill colonies) in bees. The benefit of this project is that the identification of the gene should help identify potentially invasive ant species and help prevent the social cancers that affect commercial beekeeping in South Africa from spreading world-wide.Read moreRead less
