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
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.
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.
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.

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.

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
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.

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
