The recovery of seagrass beds: the role of catchments and options for management responses. Seagrass beds once dominated tidal flats but are disappearing at an increasing rate due to human actions, both in Australia and around the world. This project will develop an understanding of the processes that cause these losses, the factors that prevent seagrass-bed re-establishment, and provide a framework for evaluating alternative management options.
Finding damage thresholds in pyrethrum to optimise crop profitability. This project aims to use a new vascular approach to develop a quantitative stress tolerance framework for the crop species pyrethrum, defining the risks to plant production of water, heat and frost stress. Using novel optical and x-ray technology, this project seeks to pinpoint damaging stress thresholds and combine this knowledge with crop monitoring technology in a way that will allow crop managers to avoid damaging stress ....Finding damage thresholds in pyrethrum to optimise crop profitability. This project aims to use a new vascular approach to develop a quantitative stress tolerance framework for the crop species pyrethrum, defining the risks to plant production of water, heat and frost stress. Using novel optical and x-ray technology, this project seeks to pinpoint damaging stress thresholds and combine this knowledge with crop monitoring technology in a way that will allow crop managers to avoid damaging stress events. The intended outcome is to enable the pyrethrum industry, and ultimately a diversity of crop managers, to better utilise new advances in monitoring technology to maximise the benefits of irrigation such that yields are high relative to water use and damage by stress is avoided. Immediate beneficiaries will be the pyrethrum industry, but the research will provide a model, applicable to the multitude of irrigated crops in Australia. Read moreRead less
Pelagic ecosystem linkages in a changing Southern Ocean. Our study, which aims to better describe and understand the ecology of the vast Ocean to the south of Australia, will provide the information that will assist in managing this region in an era of change. Many species are of significant conservation concern, others are recovering from previous harvesting, some are being harvested and all will be affected by a changing climate. Understanding the ecosystem linkages and the way in which the p ....Pelagic ecosystem linkages in a changing Southern Ocean. Our study, which aims to better describe and understand the ecology of the vast Ocean to the south of Australia, will provide the information that will assist in managing this region in an era of change. Many species are of significant conservation concern, others are recovering from previous harvesting, some are being harvested and all will be affected by a changing climate. Understanding the ecosystem linkages and the way in which the physical environment affects the distribution and abundance of key ecosystem components will allow us to better manage the system and to predict the effects of future climate change.

Tackling marine conservation issues at national and global scales. This project aims to collect and apply standardised underwater data on fishes, invertebrates and plants in an unprecedented global analysis of decadal change in rocky and coral reef ecosystems. Outcomes will include validation of global models of ocean warming and understanding of poorly known ecological impacts of recreational fisheries. A suite of data-informed recommendations developed through engagement across management, sci ....Tackling marine conservation issues at national and global scales. This project aims to collect and apply standardised underwater data on fishes, invertebrates and plants in an unprecedented global analysis of decadal change in rocky and coral reef ecosystems. Outcomes will include validation of global models of ocean warming and understanding of poorly known ecological impacts of recreational fisheries. A suite of data-informed recommendations developed through engagement across management, science and public sectors will benefit Australians by enabling improved sustainability of resource use. International benefits will propagate through increased data access, improvements in predictive models and the evidence base required for large-scale biodiversity-related policy reform.Read moreRead less
Resolving the warming East Australian Current's impact on a marine food web. Resolving the warming East Australian Current's impact on a marine food web. This project aims to understand the effects of climate change on marine food webs, from plankton production to predation by iconic marine fauna, by integrating data on oceanographic conditions and fish distribution with the foraging patterns and breeding success of seabirds. Warming waters due to strengthening western boundary currents have unk ....Resolving the warming East Australian Current's impact on a marine food web. Resolving the warming East Australian Current's impact on a marine food web. This project aims to understand the effects of climate change on marine food webs, from plankton production to predation by iconic marine fauna, by integrating data on oceanographic conditions and fish distribution with the foraging patterns and breeding success of seabirds. Warming waters due to strengthening western boundary currents have unknown consequences for coastal marine food webs. Innovative prey capture signatures from accelerometers, and advanced movement models from satellite locations will show how predators locate and prey upon fish schools. Anticipated outcomes are insight into how changing resource availability in the oceans affects ecosystem resilience; improved viability for coastal industries; and ecosystem-based conservation management strategies.Read moreRead less
Dynamic resilience and stability properties of marine systems: the importance of environment-engineer feedbacks in kelp forests. Kelp forests form complex habitats that support diverse, productive and economically important food-webs. This project will determine whether healthy kelp forests engineer their environment to make conditions more suitable for their continued recruitment and survivorship, thus increasing their stability and resilience in response to anthropogenic threats.
Restoring diverse native vegetation using drone-based precision seeding . This project aims to make drone technology a viable solution for scaling up the restoration of native vegetation on degraded land. By integrating new research in plant ecology, microbiology and environmental economics the project aims to fill key knowledge gaps about the viability and application of drones in restoration. Expected outcomes are world-first research into the delivery of beneficial soil microbes using drones ....Restoring diverse native vegetation using drone-based precision seeding . This project aims to make drone technology a viable solution for scaling up the restoration of native vegetation on degraded land. By integrating new research in plant ecology, microbiology and environmental economics the project aims to fill key knowledge gaps about the viability and application of drones in restoration. Expected outcomes are world-first research into the delivery of beneficial soil microbes using drones and the first assessment globally of the cost-effectiveness of drone restoration utilizing data from spatial analysis and extensive field trials. This should provide wide-ranging benefits for local land managers restoring remote degraded land and aid in reversing the cumulative effects of habitat loss on biodiversity. Read moreRead less
