Promoting resilience of ecosystems through connectivity. The resilience of ecosystems in the face of major environmental disturbances is emerging as a major concern for modern ecology. Connectivity of ecosystem components is a critically important element of ecosystem function and should, theoretically, be central to system resilience. The relationship between connectivity and resilience, however, remains poorly substantiated by empirical data.

The resilience of ecosystems in the face of major environmental disturbances is emerging as a major concern for modern ecology. Connectivity of ecosystem components is a critically important element of ecosystem function and should, theoretically, be central to system resilience. The relationship between connectivity and resilience, however, remains poorly substantiated by empirical data. By manipulating connectivity in laboratory experiments using a well-understood model marine system, the project aims to determine how connectivity affects resilience. It could provide a crucial step towards integrating connectivity into management and conservation of natural resources.Read moreRead less

This project aims to provide theory and practical guidelines to integrate ecosystem science into policy and action to address human well-being. Ecosystem risk assessment provides critical information for conservation, and has compelling but unexplored relationships with human health and nature’s benefits to people. The research will identify ecosystem measures that highlight areas of risk to human well-being as well as biodiversity. Expected outcomes include new standards for including ecosystem change in policy frameworks globally and in Australia, such as natural capital accounting and United Nations Sustainable Development Goals. Benefits include improved ways of meeting and tracking progress on Australia’s international commitments.Read moreRead less

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

Summary
Using food web theory to conserve ecosystems. Species interact with each other and the management of one species can impact on other species. These interactions are often ignored in conservation decision making. Food web theory is the obvious basis for considering links between species when making conservation decisions, but actually contains little explicit guidance for the management of multiple species. Using a novel application of optimisation approaches pioneered in artificial intelligence ....Using food web theory to conserve ecosystems. Species interact with each other and the management of one species can impact on other species. These interactions are often ignored in conservation decision making. Food web theory is the obvious basis for considering links between species when making conservation decisions, but actually contains little explicit guidance for the management of multiple species. Using a novel application of optimisation approaches pioneered in artificial intelligence research, we aim to demonstrate how food web theory can guide the management of multiple species. In doing so, we will also test the effectiveness of widely used approaches to multi-species management, such as keystone species, umbrella species and bottom-up control.Read moreRead less

This project aims to develop a type-based framework for the world's ecosystems, and undertake the first broad-scale global risk assessment for ecosystems. It will include detailed Australian risk assessments and scenario analyses to develop sustainable management of ecosystem services and climate adaptation strategies. The outcomes include a global-scale framework for classifying terrestrial, freshwater and marine ecosystems, the first global Red List of Ecosystems and identified priorities for protecting remaining wild ecosystems and restoring those that have suffered degradation. This will help meet UN Sustainable Development Goals to improve human well-being globally.Read moreRead less
How will the biodiversity crisis affect vital ecosystem functions? Loss of biodiversity due to environmental change is a potentially serious issue for the sustainability of ecosystems. Predictions on how biodiversity loss will affect ecosystem functions and services require a well-developed understanding of its effects on plant litter decomposition, because this process is a key component of the global carbon cycle. This project will advance this understanding by addressing several key questions ....How will the biodiversity crisis affect vital ecosystem functions? Loss of biodiversity due to environmental change is a potentially serious issue for the sustainability of ecosystems. Predictions on how biodiversity loss will affect ecosystem functions and services require a well-developed understanding of its effects on plant litter decomposition, because this process is a key component of the global carbon cycle. This project will advance this understanding by addressing several key questions (for example, relative importance of decomposition versus other drivers of environmental change; and temporal variation in biodiversity effects on decomposition), using forest streams as model systems. These experiments will mimic realistic extinction events across climatic gradients, enabling predictions to be made at large scales.Read moreRead less

Catastrophic shifts: the value of knowing more about ecosystem feedbacks. Ecosystems respond to gradual change in unexpected ways. Feedback processes between different parts of an environment can perpetuate ecosystem collapse, leading to potentially irreversible biodiversity loss. However, it is unclear if greater knowledge of feedbacks will ultimately change environmental decisions. The project aims to identify when feedbacks matter for environmental decisions, by generating new methods that pr ....Catastrophic shifts: the value of knowing more about ecosystem feedbacks. Ecosystems respond to gradual change in unexpected ways. Feedback processes between different parts of an environment can perpetuate ecosystem collapse, leading to potentially irreversible biodiversity loss. However, it is unclear if greater knowledge of feedbacks will ultimately change environmental decisions. The project aims to identify when feedbacks matter for environmental decisions, by generating new methods that predict the economic benefit of knowing more about feedbacks. Combining ecological modelling and value-of-information theory, the outcomes of these novel methods will provide significant and broad environmental benefits, by enabling managers to make informed decisions and stay one step ahead of potential ecosystem collapse.Read moreRead less

This project aims to discover the ecological and functional roles of cyanobacteria in drylands, and develop new technologies for their broad application in large-scale ecosystem restoration. The global demand for landscape-scale restoration requires novel approaches to deliver on the promise of reinstating healthy, sustainable, and biodiverse ecosystems. This project will harness next-generation DNA sequencing to select beneficial cyanobacteria for incorporation into emerging seed enhancement technologies. The project will deliver innovative and cost-effective tools to overcome barriers to seedling recruitment and plant survival, and enhance the functionality of degraded dryland ecosystems. This will contribute to long-term cost savings to the Australian economy through reduced spending on environmental issues such as salinity, erosion, acidification and poor water quality.Read moreRead less
