Do hotter and drier regions harbour adaptive variation for climate change? This project aims to improve our understanding of the capacity of trees to respond to climate change. This is essential for the maintenance of biodiversity, forest health and productivity. In south-west Australia, climate variation has increased the frequency and intensity of droughts, which has resulted in tree death and negatively affected essential ecosystem services. Adaptive land management is urgently needed to miti ....Do hotter and drier regions harbour adaptive variation for climate change? This project aims to improve our understanding of the capacity of trees to respond to climate change. This is essential for the maintenance of biodiversity, forest health and productivity. In south-west Australia, climate variation has increased the frequency and intensity of droughts, which has resulted in tree death and negatively affected essential ecosystem services. Adaptive land management is urgently needed to mitigate the risk of large-scale drought mortality in a rapidly changing climate. This project seeks to deliver a scientific basis for the adoption of assisted gene migration in south-west forests, through a detailed understanding of genetic adaptation and physiological tolerance, to improve drought-resilience under future hotter and drier climates.Read moreRead less
Building giants: the origins of extreme biology in baleen whales. Baleen whales are unlike any other animal. They have evolved unparalleled specialisations for feeding, hearing, smell, cognition and – above all – the largest ever body size. These extreme features underlie the unmatched dominance of baleen whales in today's oceans. The origins of these key adaptations required major changes in the anatomy and function of the skull and teeth. However, exactly how and when the extreme innovations o ....Building giants: the origins of extreme biology in baleen whales. Baleen whales are unlike any other animal. They have evolved unparalleled specialisations for feeding, hearing, smell, cognition and – above all – the largest ever body size. These extreme features underlie the unmatched dominance of baleen whales in today's oceans. The origins of these key adaptations required major changes in the anatomy and function of the skull and teeth. However, exactly how and when the extreme innovations of baleen whales began remains an outstanding question in animal biology. This proposal aims to combine exceptional Australian fossils with recent advances in 3D imaging, biomechanics, and evolutionary analysis to discover how the secrets to the success of baleen whales first evolved.Read moreRead less
Imaging the world of miniature venomous arthropods. Venomous arthropods produce a myriad of biologically active peptides, with many having potential as pharmacological tools, bioinsecticides and pharmaceuticals. Most studies to date have focussed on large arthropods; smaller species remain neglected due to the difficulties of venom collection. This project seeks to further advance the pioneering imaging mass spectrometry approaches the project team developed for imaging toxins in the venom gland ....Imaging the world of miniature venomous arthropods. Venomous arthropods produce a myriad of biologically active peptides, with many having potential as pharmacological tools, bioinsecticides and pharmaceuticals. Most studies to date have focussed on large arthropods; smaller species remain neglected due to the difficulties of venom collection. This project seeks to further advance the pioneering imaging mass spectrometry approaches the project team developed for imaging toxins in the venom glands of spiders and centipedes. By combining high-resolution matrix-assisted laser desorption ionisation imaging data with histological and transcriptomic information the project aims to provide the first detailed insights into the neglected world of miniature arthropod venoms. The approaches developed by this project aim to have wide application in the field of biology.Read moreRead less
Planning for a transformed future: Modelling synergistic climate change and land use impacts on biodiversity. Climate change poses a dire threat to Australia's biodiversity and natural resources due to its all-encompassing reach and the speed at which human-driven changes are taking place in already heavily modified systems.

Climate change poses a dire threat to Australia's biodiversity and natural resources due to its all-encompassing reach and the speed at which human-driven changes are taking place in already heavily modified systems. The proposed research, on modelling the synergistic impacts of anthropogenic threats, will provide new knowledge and innovative solutions for protecting unique ecosystems facing severe environmental challenges this century. The validation of these new methods, which aim to capture ecological responses to global change, will represent a major and timely addition to the national research capability on climate change adaptation, and add to Australia's reputation as a global leader in the field of ecology.Read moreRead less
Integrative assessment of disturbance and land-use change on total greenhouse gas balance and nutrient cycling in savanna ecosystems. Climate change and variability is expected to have an impact on the NT environment and economy.

Climate change and variability is expected to have an impact on the NT environment and economy. This project will enable NT specific calibrations of climate variability-land use models, such as the National Carbon Accounting System. The NT Government will have access to a high quality database and calibrated models relating to greenhouse gas emissions as a function of land use change. The project will improve estimates and management of GHG and provide a basis for the NT to potentially exploit future carbon-trading initiatives or GHG abatement schemes as fundamental data describing emissions as a function of land use will be available. This is of national significance given the size of the savanna biome in Australia.Read moreRead less
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. 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 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
Providing a genetic framework to enhance the success and benefits from forest restoration and carbon plantings in rural landscapes. This project will provide a genetic framework to inform strategies for climate change adaptation in forest restoration and carbon plantings in Australia. Key questions to be addressed include the value of local versus non-local seed sources and the role of tree genetics in shaping biodiversity and other ecosystem services.
Fires, black carbon, greenhouse gas emissions and the carbon balance of southern sclerophyll forests. Ecologically sustainable forest management requires an understanding of the role of fire in the carbon balance of native forests, and in Australia's overall carbon balance. Fires are crucial to both this carbon balance and to the ecology of the forests. This project will help forest managers make decisions about using prescribed fire to manage fuels while at the same time managing carbon. An ....Fires, black carbon, greenhouse gas emissions and the carbon balance of southern sclerophyll forests. Ecologically sustainable forest management requires an understanding of the role of fire in the carbon balance of native forests, and in Australia's overall carbon balance. Fires are crucial to both this carbon balance and to the ecology of the forests. This project will help forest managers make decisions about using prescribed fire to manage fuels while at the same time managing carbon. An aim of management is to identify fire regimes that will optimise the carbon outcome as well as provide protection to life and property. This project will help managers meet that aim by developing a quantitative understanding of how much stable, black carbon (charcoal) is produced and how it affects other soil processes.Read moreRead less
