Vulnerability of Australian savannas to climate change and variability. Australian savannas are productive and are culturally and biologically significant landscapes, but they are vulnerable to climate change. This project will determine savanna function (carbon and water balance) for the present and assess how sensitive they have been to past climate variability. The project will then address how they may respond to future climate change.
Assessing the ecosystem-wide risks of threatened species translocation. Assessing the ecosystem-wide risks of threatened species translocation. This project aims to develop the first quantitative risk assessment framework to improve decisions about moving threatened species to new places. Moving threatened plants and animals to new environments, or reintroducing them where they previously persisted, is a growing focus of conservation. Moving species can have unanticipated effects on other specie ....Assessing the ecosystem-wide risks of threatened species translocation. Assessing the ecosystem-wide risks of threatened species translocation. This project aims to develop the first quantitative risk assessment framework to improve decisions about moving threatened species to new places. Moving threatened plants and animals to new environments, or reintroducing them where they previously persisted, is a growing focus of conservation. Moving species can have unanticipated effects on other species in the ecosystem. Although the International Union for Conservation of Nature deems ecosystem-wide risk assessments essential for conservation translocations, no framework exists to assess these risks and inform these decisions. New tools for assessing the risks of conservation translocations are expected to improve global and local conservation outcomes.Read moreRead less
Global change and food web structure: synergistic effects of multiple drivers of global change on species interaction networks. This project addresses the two great challenges facing scientists trying to predict the effects of global change on Australia's ecosystems: i) What factors most exacerbate the total impact of global change? ii) How do the complex responses of so many interacting species actually translate into altered structural properties of the web of life?
Is restoration working? An ecological genetic assessment. This project aims to assess the success of restoration in terms of ecological and genetic viability for plant species in the Fitzgerald River–Stirling Range region of Western Australia, where significant investment is being made in restoring connectivity at a landscape scale. The project intends to compare reproductive output, pollinator behaviour, mating, genetic diversity and pollen dispersal in restored sites with those of undisturbed ....Is restoration working? An ecological genetic assessment. This project aims to assess the success of restoration in terms of ecological and genetic viability for plant species in the Fitzgerald River–Stirling Range region of Western Australia, where significant investment is being made in restoring connectivity at a landscape scale. The project intends to compare reproductive output, pollinator behaviour, mating, genetic diversity and pollen dispersal in restored sites with those of undisturbed natural vegetation. The project moves measures of restoration success beyond that of population establishment and survival to incorporate the evolutionary processes that provide long-term resilience, persistence and functional integration of restored populations into broader landscapes.Read moreRead less

A key outcome of the research will be providing tangible benefits to all Australians by building bridges between the natural and social sciences, strengthening capacity, and informing and supporting transformative changes in coral reef governance and management.Read moreRead less
Is the extreme phosphate sensitivity found among Australian plants a consequence of their adaptation to a severely phosphate-limited environment? The phosphorus (P)-impoverished soils of south-western Australia have allowed the evolution of many plants that are amazingly efficient at retrieving P from dying tissues. This project will contribute to the understanding of the mechanism determining P efficiency and will contribute significantly to the development of crops that are less reliant on non ....Is the extreme phosphate sensitivity found among Australian plants a consequence of their adaptation to a severely phosphate-limited environment? The phosphorus (P)-impoverished soils of south-western Australia have allowed the evolution of many plants that are amazingly efficient at retrieving P from dying tissues. This project will contribute to the understanding of the mechanism determining P efficiency and will contribute significantly to the development of crops that are less reliant on non-renewable P fertilisers.Read moreRead less

By manipulating genetic diversity, local selection and gene flow in restored plant communities, this project will establish suitable regimes to manage evolutionary processes in large-scale restoration, thereby improving success and resilience to future changes. It will significantly advance our understanding of evolutionary processes operating in restoration efforts, and lead to improved restoration success, better long-term ecological functioning in restored ecosystems, better investment of resources, and maintenance of Australia’s biodiversity in the face of rapid environmental change. These findings should be of relevance to broader restoration initiatives managed by the government, community, and industry nationally and internationally.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

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
Unravelling the cycling of nitrogen along a subtropical freshwater-marine continuum using a multi-isotope, multi-tracer and modelling approach. This project will significantly advance our understanding of the sources, cycling and pathways of nitrogen along a sub-tropical catchment-river-estuary. As such, the findings from this research will have direct implications to the management, rehabilitation and protection of waterways (including biodiversity) in Australia.
