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
The ecological impact of large carnivore restoration. This project aims to assess the ecological changes that have arisen due to the repatriation of estuarine crocodiles to Australian ecosystems. It is significant because the restoration provides a rare opportunity to empirically test changes in ecosystem processes under varying degrees of large carnivore predation pressure. Expected outcomes include improved understanding of the processes that govern the strength of predator-ecosystem interacti ....The ecological impact of large carnivore restoration. This project aims to assess the ecological changes that have arisen due to the repatriation of estuarine crocodiles to Australian ecosystems. It is significant because the restoration provides a rare opportunity to empirically test changes in ecosystem processes under varying degrees of large carnivore predation pressure. Expected outcomes include improved understanding of the processes that govern the strength of predator-ecosystem interactions and an ability to quantify the biomass, social structure, and behaviours of predators required to influence these processes. Benefits should include improvements in how the ecological role of large carnivores is measured, and when and where carnivore populations should be culled or conserved.Read moreRead less

Conserving and recovering the koala populations on NSW Far North Coast. This project aims to develop a novel, integrated socio-ecological approach for connecting landscapes and communities for the recovery of threatened koala populations on the New South Wales far north coast. This should increase understanding of how local landholders and land managers respond to koala recovery programs and why they respond positively and become engaged for the long-term. The intended outcome is a spatial prioritisation framework for species recovery that integrates social and ecological values, and increased global knowledge of how to recover declining wildlife populations.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
From prediction to adaptation: responding to rapid ecosystem shifts under climate change. Nobody knows exactly how climate change will affect the ecosystems on which we depend for our own existence, though negative impacts are widely predicted. This project integrates mathematical, economic and ecological approaches to learn about the most effective way to spend limited funds for sustaining ecosystems threatened by climate change.
Global climate change and the impacts of temperature extremes on terrestrial biodiversity. Increasing severity of climate extremes is a disturbing implication of global climate change; yet little is known about the effects of such extremes on the natural world. This project aims to understand the vulnerability of biodiversity to current and future extremes, and to inform conservation efforts and minimise future impacts.

Science-based management of coral reefs provides enormous environmental, social and economic benefit to Australia and other tropical maritime nations. The proposed research will provide scientific knowledge and research training that underpins the management and long-term sustainability of Australian reef resources. Climate change research is vital for supporting the sustainable use of the ecosystem goods and services provided by reef ecosystems (e.g. to tourism and fishing industries, recreational users and indigenous Australians). This research will place Australia in the forefront of understanding and responding to the regional-scale impacts of climate change on tropical societies and economies.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

This project aims to investigate the capacity of farm dam management strategies to simultaneously support nature conservation and agricultural production. The project expects to generate new knowledge in the areas of conservation biology and sustainable agriculture by using experiments that identify the interdependence of cattle grazing and habitat quality of wetlands. Anticipated outcomes include a framework for evaluating management strategies in terms of their dual capacity to support aquatic wildlife and livestock production. Significant benefits include increased productivity through the improved management of wetlands and dams on farms and the recogniton of undervalued conservation resources.Read moreRead less
Rehabilitating a changing landscape: using the latest advances in koala ecology to direct adaptive management. The koala has been identified as one of the world's flagship species suffering from environmental change. In contrast to the decline of koalas in New South Wales generally, the eucalypts planted in Gunnedah to combat salinity led to an increase in koalas. However, the startlingly high death rate of Gunnedah koalas (25 per cent of the population) in the heatwave during the drought in 200 ....Rehabilitating a changing landscape: using the latest advances in koala ecology to direct adaptive management. The koala has been identified as one of the world's flagship species suffering from environmental change. In contrast to the decline of koalas in New South Wales generally, the eucalypts planted in Gunnedah to combat salinity led to an increase in koalas. However, the startlingly high death rate of Gunnedah koalas (25 per cent of the population) in the heatwave during the drought in 2009 must be understood. There are also new threats brought about by intensive land modification. This project aims to determine the effects of environmental change on the koala population through a study of landscape ecology, leaf chemistry, disease epidemiology and koala movements. This aims to lead to better management decisions for arboreal fauna.Read moreRead less
