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
Planning for the impacts of land-uses on coral reef fisheries. This projects aims to develop models that can determine the ecological and economic impacts of land-use changes (e.g. agriculture) on fisheries and assess alternative land-use plans that seek to maximise economic opportunity while protecting fisheries. Fisheries support the livelihoods of 12 per cent of the world’s population. Land-based activities are among the most significant threats to coral reef fisheries because sediments and n ....Planning for the impacts of land-uses on coral reef fisheries. This projects aims to develop models that can determine the ecological and economic impacts of land-use changes (e.g. agriculture) on fisheries and assess alternative land-use plans that seek to maximise economic opportunity while protecting fisheries. Fisheries support the livelihoods of 12 per cent of the world’s population. Land-based activities are among the most significant threats to coral reef fisheries because sediments and nutrients degrade reefs, yet they are often ignored in fisheries management. By improving the sustainability of coastal development, biodiversity conservation, and health of fisheries, the models developed by the project could deliver socio-economic and environmental benefits for millions of people reliant upon fisheries for their livelihoods.Read moreRead less
Understanding snow gum dieback for effective and integrated management. The project leverages recent research and infrastructure investments and our determined and collaborative team as it aims to: 1) assess the future geography of snow gum dieback in the high country and identify priority locations for pro-active management, 2) quantify the impact of snow gums on high country water and carbon budgets and thus the socio- economic and biodiversity values, and 3) determine options for mitigation. ....Understanding snow gum dieback for effective and integrated management.

Dieback of our iconic snow gum forests is diminishing the ecological, hydrological and cultural values of the Australian Alps and will impact state and national water-supply and power-generation systems. Our research will inform Alps-wide management efforts designed for long-term success.Read moreRead less
Tipping points and early warning signals in complex ecosystems. This project aims to create a theory of early warning that uses spatial data available on system state, connectivity and environmental stress, and to create tools to infer the risk of ecosystem collapse. Many ecosystems have irreversible tipping points. Since their locations are often unknown, metrics may provide an early warning of collapse but are difficult to apply because they need long time series which are usually lacking. Thi ....Tipping points and early warning signals in complex ecosystems. This project aims to create a theory of early warning that uses spatial data available on system state, connectivity and environmental stress, and to create tools to infer the risk of ecosystem collapse. Many ecosystems have irreversible tipping points. Since their locations are often unknown, metrics may provide an early warning of collapse but are difficult to apply because they need long time series which are usually lacking. This project will use the Great Barrier Reef as a testbed because it has both long time series (standard approach) and rich spatial data (new approach), and exhibits early warning signs. We will use these tools to gauge whether symptoms on the Great Barrier Reef predict local collapse and to develop intervention plans.Read moreRead less

Summary
Unravelling how ecosystems function through time and space. This project aims to build a whole-of-ecosystem model to trace the biological capture of energy and cycling of matter as it moves through entire river catchments. It is expected to generate new knowledge about ecological responses to environmental streamflow through the novel integration of all major food-web compartments – from dissolved molecules to predatory fish – in a single framework. The expected outcome of this project is an enh ....Unravelling how ecosystems function through time and space. This project aims to build a whole-of-ecosystem model to trace the biological capture of energy and cycling of matter as it moves through entire river catchments. It is expected to generate new knowledge about ecological responses to environmental streamflow through the novel integration of all major food-web compartments – from dissolved molecules to predatory fish – in a single framework. The expected outcome of this project is an enhanced capacity to predict the ecological consequences of future water management scenarios, facilitating more precise management of river systems. This should provide considerable benefits to the health of Australia’s rivers and the contributions these ecosystems make to society, environment, and agriculture.Read moreRead less
Investigating movement, distribution, abundance and diet to support management objectives for threatened riverine predators in Northern Australia. The rivers and estuaries of northern Australia are highly productive environments, containing an exceptional diversity and abundance of large predatory aquatic species.

Movement data will b ....Investigating movement, distribution, abundance and diet to support management objectives for threatened riverine predators in Northern Australia. The rivers and estuaries of northern Australia are highly productive environments, containing an exceptional diversity and abundance of large predatory aquatic species. This project aims to monitor the movements, habitat preferences and diet in eight large predatory species in a northern Queensland river over the next three years. Movement data will be combined with isotopic analysis to reveal how environmental and biological factors drive animal movements and impact habitat connectivity. In a world of vanishing top predators, it is imperative to understand system dynamics before we can evaluate the impact of species removal on ecosystem function.Read moreRead less
Cascading effects of Australia's ecological extinctions on biodiversity and ecosystem function. The current rate of species extinctions is so extensive that it has been described as the “sixth mass extinction”. In Australian ecosystems, extinctions and declines of mammals have been dramatic, with formerly abundant species now “ecologically extinct”, meaning they are too rare to continue to play important ecological roles. The loss of entire functional guilds may have cascading effects on biodive ....Cascading effects of Australia's ecological extinctions on biodiversity and ecosystem function. The current rate of species extinctions is so extensive that it has been described as the “sixth mass extinction”. In Australian ecosystems, extinctions and declines of mammals have been dramatic, with formerly abundant species now “ecologically extinct”, meaning they are too rare to continue to play important ecological roles. The loss of entire functional guilds may have cascading effects on biodiversity and ecosystem function. This project uses a multi-scalar experimental approach to investigate the broader impacts of mammal declines on Australian ecosystems, accounting for interactions with climate. The outcomes will include new insights into the pre-European state of Australian ecosystems and more realistic targets for ecosystem restoration.Read moreRead less
Maintaining biodiversity and ecological resilience in the face of global environmental change. 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?

The project will develop and test a new global standard for the assessment and reporting on ecological condition of internationally important wetlands, listed under the Ramsar Convention. It has four aims: establishment of a strategic adaptive management and governance framework, a meta-analysis of the 2,303 internationally listed wetlands, development of a protocol for assessment and prediction and delivering a digital reporting platform for effective management. The project is significant because it tackles the decline of freshwater ecosystems, by targeting the most prominent wetlands. It also assists state and national governments to meet their obligations under the Ramsar Convention and most importantly guides more effective management.Read moreRead less
