Is a grass-fire cycle reducing biodiversity in the stone country of Kakadu National Park? There is concern that bushfires in northern Australia are causing biodiversity loss. The project will compare fire regimes and populations of a fire-sensitive tree, Callitris intratropica, in Kakadu to similar areas in central Arnhem Land, to see how fire management can be optimised to prevent further biodiversity loss on the Arnhem Plateau.
Have we already lost the Australian lungfish? This project aims to use radiocarbon ageing, conservation genetics and modelling to identify threats to the long-term survival of the Australian lungfish, the world's oldest living vertebrate. This project will provide managers with a powerful tool to prioritise management interventions to ensure the conservation of the species and to pull it back from extinction.
Using pollinators to optimise plant conservation translocation. This project aims to address the low success rate of conservation translocations of threatened orchids. While pollinators are critical for plant reproduction, they are very rarely considered when establishing new populations of endangered species. Our innovative approach to conservation translocation involves using pollinators in site selection, developing strategies to mitigate risks of hybridisation, and optimising plant reproduct ....Using pollinators to optimise plant conservation translocation. This project aims to address the low success rate of conservation translocations of threatened orchids. While pollinators are critical for plant reproduction, they are very rarely considered when establishing new populations of endangered species. Our innovative approach to conservation translocation involves using pollinators in site selection, developing strategies to mitigate risks of hybridisation, and optimising plant reproduction through planting design. The key outcome will be best-practice protocols to fast-track the establishment of self-sustaining populations. Due to their novelty, the approaches we develop will benefit plant translocations worldwide, and lead to enhanced conservation outcomes at reduced financial cost. Read moreRead less
Developing Assisted Reproductive Technologies for the Conservation of Critically Endangered Australian Amphibians. Unprecedented rates of species extinction are of global concern. Although high extinction rates are reported for all vertebrate classes, amphibians are the most severely affected. Captive-breeding programs play a key role in maintaining populations of endangered amphibian species, but in most cases reproductive rates are too low to support long term re-introduction programmes. This ....Developing Assisted Reproductive Technologies for the Conservation of Critically Endangered Australian Amphibians. Unprecedented rates of species extinction are of global concern. Although high extinction rates are reported for all vertebrate classes, amphibians are the most severely affected. Captive-breeding programs play a key role in maintaining populations of endangered amphibian species, but in most cases reproductive rates are too low to support long term re-introduction programmes. This study aims to develop sophisticated Assisted Reproductive Technologies (ART) to enhance the propagation and genetic management of endangered Australian frog species. ART is a powerful new approach to ex situ conservation that, if integrated into existing captive breeding programs, will ensure the preservation of Australia’s unique amphibian biodiversity.Read moreRead less
Genetic rescue of Australian wildlife. Genetic rescue of Australian wildlife. This project aims to test genetic rescue as an efficient recovery technique for threatened plants and animals. Genetic rescue is under-utilised, even though it is overwhelmingly beneficial. This project will convert management actions on five Endangered/Critically Endangered species into rigorous experiments that measure the fitness benefits of genetic rescue, and demonstrate genome-wide consequences. Anticipated outco ....Genetic rescue of Australian wildlife. Genetic rescue of Australian wildlife. This project aims to test genetic rescue as an efficient recovery technique for threatened plants and animals. Genetic rescue is under-utilised, even though it is overwhelmingly beneficial. This project will convert management actions on five Endangered/Critically Endangered species into rigorous experiments that measure the fitness benefits of genetic rescue, and demonstrate genome-wide consequences. Anticipated outcomes include innovative genetic rescue protocols, a framework for genetic rescue, and leading-edge conservation training. Expected benefits are increased persistence of species that are otherwise unresponsive to management, and a new path to saving endangered species.Read moreRead less
How isolated is Antarctica? Assessing past and present plant colonisations. The project aims to assess how biologically isolated Antarctica is by discovering how, when and where natural colonisations of the continent have occurred. The research will focus on mosses, the dominant plant group in the Antarctic. genomic tools will be combined with environmental, spatial, and ecological data to assess mechanisms and directions of dispersal to and around Antarctica, and to predict areas most likely to ....How isolated is Antarctica? Assessing past and present plant colonisations. The project aims to assess how biologically isolated Antarctica is by discovering how, when and where natural colonisations of the continent have occurred. The research will focus on mosses, the dominant plant group in the Antarctic. genomic tools will be combined with environmental, spatial, and ecological data to assess mechanisms and directions of dispersal to and around Antarctica, and to predict areas most likely to be colonised in the future. This will help understand the processes underpinning the evolution and diversity of Antarctic species, and the vulnerability and adaptability of Antarctic ecosystems. Read moreRead less
Evolution of Australia's globally unique hotspot of floral diversity. Australia has a globally recognised biodiversity hotspot, the southwest of Western Australia, but this unique eucalypt-dominated flora is threatened. This project will gain new insights into the evolutionary processes that generate and maintain such diversity, their vulnerability; and how the iconic eucalypts came to dominate the Australian landscape.
Preventing and reversing population declines of northern quolls. This project seeks to develop novel effective strategies to halt and reverse declines in northern quolls by improving their ‘toad-smart’ behaviour. The spread of cane toads threaten northern quolls, which are marsupial predators. We cannot halt the toad invasion, but we can train quolls not to eat cane toads. Trained quolls can survive long term in toad-infested landscapes, and their offspring can learn not to eat toads. This proje ....Preventing and reversing population declines of northern quolls.

Trained quolls can survive long term in toad-infested landscapes, and their offspring can learn not to eat toads. This project builds on this work by focusing on cultural and genetic transmission of toad-smart behaviour. The project could save numerous quoll populations from extinction.Read moreRead less

Summary
Why do some declining species persist while others go extinct? Global change is driving thousands of species towards extinction. Legislation requires the protection of biodiversity, but current scientific understanding of species declines limits effective action. By taking a new approach to studying species declines, this integrative research aims to identify why some species persist, while others decline. This project is expected to improve understanding of species vulnerability to extinction, ....Why do some declining species persist while others go extinct? Global change is driving thousands of species towards extinction. Legislation requires the protection of biodiversity, but current scientific understanding of species declines limits effective action. By taking a new approach to studying species declines, this integrative research aims to identify why some species persist, while others decline. This project is expected to improve understanding of species vulnerability to extinction, and the conditions which allow species to coexist with threats. Anticipated benefits include advancing ecological theory, improving conservation planning, and increasing the efficiency and effectiveness of policy and management to prevent species extinctions.Read moreRead less
Genomics for persistence of Australian freshwater fish. Biodiversity faces an unpredictable cocktail of impacts and global environmental change, against which the best insurance is genetic diversity. We will develop genomic measures of ecological-genetic functions and evolutionary potential for managing Australian freshwater fish.
