The most significant environmental challenges facing Australia include ensuring sustainable management of our water resources and conservation of both terrestrial and marine biodiversity, particularly in the face of our changing climate and land-use. The new instruments will accelerate progress across a number of projects aimed at understanding the development of groundwater resources, the relative dependency of ecosystems on groundwater versus soil and surface water, and an assessment of the likely impacts of altered hydrology, especially dewatering and salinisation, on ecosystems. In addition, they will also be used to extend our knowledge of climate variability in the recent past and increase understanding of critical marine resources.Read moreRead less
Tracking squids from embryos to adults - novel approaches and new directions. Cutting edge acoustic tracking technology, combined with traditional tagging techniques and novel applications of trace element analysis, will allow for the life cycle of squid to be tracked through space and time - from embryonic stages through to spawning adults. Southern calamary earbones will be examined for evidence of elemental 'fingerprints' that reveal where they came from as hatchlings. This combined with trac ....Tracking squids from embryos to adults - novel approaches and new directions. Cutting edge acoustic tracking technology, combined with traditional tagging techniques and novel applications of trace element analysis, will allow for the life cycle of squid to be tracked through space and time - from embryonic stages through to spawning adults. Southern calamary earbones will be examined for evidence of elemental 'fingerprints' that reveal where they came from as hatchlings. This combined with tracking squid in Australia's biggest marine acoustic listening grid, will allow unprecedented resolution of squid life cycles. Commercial, recreational and managerial sectors are collaborating with this research to ensure sustainable management of this commercially important and ecologically crucial species.

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.

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
The future of forests under climatic stress. This project aims to measure the vulnerability of forest trees to more extreme drought as global temperatures inevitably rise. Australian forests face the immediate threat of increased mortality associated with intensifying drought stress in the future. Understanding the magnitude of this threat is of the utmost urgency. This project aims to predict future mortality of forest communities in Australia and worldwide using recent breakthroughs enabling t ....The future of forests under climatic stress. This project aims to measure the vulnerability of forest trees to more extreme drought as global temperatures inevitably rise. Australian forests face the immediate threat of increased mortality associated with intensifying drought stress in the future. Understanding the magnitude of this threat is of the utmost urgency. This project aims to predict future mortality of forest communities in Australia and worldwide using recent breakthroughs enabling the rapid quantification of lethal stress in trees. This new understanding will provide a basis upon which to make far-reaching decisions about land management, conservation and restoration.Read moreRead less
A novel top-down approach to ecosystem management using multivariate foraging strategies of an iconic marine top-predator. Understanding predator aggregation patterns in relation to marine productivity is critical in designing ecosystem-level conservation plans for protecting marine habitats and species. The project aims to develop a new approach to measure prey abundance and availability in the marine ecosystem for the management of resources of top-predators. This will be of specific benefit i ....A novel top-down approach to ecosystem management using multivariate foraging strategies of an iconic marine top-predator. Understanding predator aggregation patterns in relation to marine productivity is critical in designing ecosystem-level conservation plans for protecting marine habitats and species. The project aims to develop a new approach to measure prey abundance and availability in the marine ecosystem for the management of resources of top-predators. This will be of specific benefit in areas where a strong need exists for conservation of prey species with economic importance too low to justify expensive at-sea research.Read moreRead less
How has bushfire activity varied around the Southern Hemisphere over the last 10,000 years? We will determine the relative contribution of climate and human ignitions in driving bushfire activity around the Southern Hemisphere over the last 10,000 years. Such knowledge is crucial for ecologically sustainable fire management, resolving debates about past Aboriginal environmental impacts and understanding the risk posed by climate change.
Effects of maternal foraging success and oceanographic variation on offspring behaviour and survival in the southern elephant seal. Juvenile survival is the key determinant of mammalian population performance, but the proximate determinants of this have rarely been established in large, long-lived predators. Southern elephant seals, with their concentrated lactation effort and marked separation of energy acquisition (at-sea foraging) and expenditure (on-land lactation) provide an ideal model for ....Effects of maternal foraging success and oceanographic variation on offspring behaviour and survival in the southern elephant seal. Juvenile survival is the key determinant of mammalian population performance, but the proximate determinants of this have rarely been established in large, long-lived predators. Southern elephant seals, with their concentrated lactation effort and marked separation of energy acquisition (at-sea foraging) and expenditure (on-land lactation) provide an ideal model for investigating these factors. In this study, we investigate the partitioning of pre-partum performance (fat acquired in mothers) relative to spatial-temporal variation in ocean productivity and the effect of this expenditure on offspring condition and survival. Here, the final missing link of energy transfer and its effects on offspring will be a major outcome of this project.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.
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
Climate change: bridging the gap between environmental induced phenotypic change, population dynamics, and long-term evolution. It is becoming impossible to ignore the impact of global climate change on organisms around the world from changes in migration, distribution to extinction events - yet there is much to understand. This project examines the role of a changing environment during developmental and its effects on ecological and evolutionary outcomes.
