Are kangaroos jeopardizing conservation outcomes? There is concern that grazing by over-abundant kangaroos is jeopardising the goals of arid conservation reserves, but there is little evidence about the extent of their impacts. The goal of this proposal is to quantify kangaroos' grazing effects on biodiversity within arid conservation reserves. The results will provide a whole ecosystem understanding of how overgrazing by kangaroos influences the biodiversity conservation value of the vast lands ....Are kangaroos jeopardizing conservation outcomes? There is concern that grazing by over-abundant kangaroos is jeopardising the goals of arid conservation reserves, but there is little evidence about the extent of their impacts. The goal of this proposal is to quantify kangaroos' grazing effects on biodiversity within arid conservation reserves. The results will provide a whole ecosystem understanding of how overgrazing by kangaroos influences the biodiversity conservation value of the vast landscapes of arid Australia. Managers of many conservation reserves, including our project partners, and policy-makers need the information that our experiments will provide to inform the development of strategies to optimise biodiversity conservation and manage the impacts of kangaroos.Read moreRead less
Preventing and reversing population declines of northern quolls. This project seeks to develop novel effective strategies to halt and reverse declines in northern quolls by improving their ‘toad-smart’ behaviour. The spread of cane toads threaten northern quolls, which are marsupial predators. We cannot halt the toad invasion, but we can train quolls not to eat cane toads. Trained quolls can survive long term in toad-infested landscapes, and their offspring can learn not to eat toads. This proje ....Preventing and reversing population declines of northern quolls. This project seeks to develop novel effective strategies to halt and reverse declines in northern quolls by improving their ‘toad-smart’ behaviour. The spread of cane toads threaten northern quolls, which are marsupial predators. We cannot halt the toad invasion, but we can train quolls not to eat cane toads. Trained quolls can survive long term in toad-infested landscapes, and their offspring can learn not to eat toads. This project builds on this work by focusing on cultural and genetic transmission of toad-smart behaviour. The project could save numerous quoll populations from extinction.Read moreRead less
Keystone effects of Australia's top predators: dingoes, devils and biodiversity. This project will study the interactions of Australia's two largest predators, the dingo and Tasmanian devil, with other species. The project will help develop an understanding of the value of these predators in maintaining ecosystem processes and diversity, and guide their management in the future.
Apex predator control of nutrient dynamics. This project aims to understand the mechanisms through which predators can control ecosystem nutrient dynamics. Ecology has been dominated for decades by the top-down/bottom-up paradigm. The project will use experiments and remote sensing observations to examine the spatial structure of feedback loops between a top predator and nutrient cycles. The expected outcome is a mechanistic and scalable understanding of the spatial distribution of nutrients and ....Apex predator control of nutrient dynamics. This project aims to understand the mechanisms through which predators can control ecosystem nutrient dynamics. Ecology has been dominated for decades by the top-down/bottom-up paradigm. The project will use experiments and remote sensing observations to examine the spatial structure of feedback loops between a top predator and nutrient cycles. The expected outcome is a mechanistic and scalable understanding of the spatial distribution of nutrients and push ecosystems towards alternate states. The project will provide innovative approaches to scale-up ecological data that can be used to inform the decisions of policy makers and land managers.Read moreRead less

This project aims to prevent further wildlife loss by creating a blueprint for the ecological restoration of urban spaces. Working with seven Councils and three State government agencies in northern Sydney, this project will experimentally assess a new approach to conservation by restoring regionally-present but locally-missing wildlife. Expected outcomes include the restoration of ecosystem services provided by wildlife and increased opportunities for community engagement with nature. Project benefits include initiating rewilding in urban areas, improved public education on the benefits of restoring wildlife and greater potential to conserve our biodiversity and cultural heritage.Read moreRead less
The endangered swift parrot as a model for managing small migratory birds. Endangered swift parrots use variable locations while breeding in eastern Tasmania and over winter on the Australian mainland. This project aims to develop effective conservation strategies for swift parrots and other migrants using new and long term data and innovative technological solutions to tracking small birds across vast landscapes.
Movement ecology of flying-foxes. This project aims to understand flying-fox movement ecology from individual navigation through to population redistribution. Understanding movement across spatiotemporal scales is a goal of movement research. Grey-headed flying-foxes are mobile, and advances in tracking technology make them ideal for studying movement across scales. This project will determine how flying foxes navigate, and integrate this with drivers of their movement to understand their moveme ....Movement ecology of flying-foxes. This project aims to understand flying-fox movement ecology from individual navigation through to population redistribution. Understanding movement across spatiotemporal scales is a goal of movement research. Grey-headed flying-foxes are mobile, and advances in tracking technology make them ideal for studying movement across scales. This project will determine how flying foxes navigate, and integrate this with drivers of their movement to understand their movement ecology by using methods that integrate experimental manipulation with telemetry, Doppler radar and analytical techniques. This is expected to develop much-needed management strategies that incorporate an understanding of movement.Read moreRead less

This project aims to quantify how bushfires amplify the impacts of invasive predators (feral cats and foxes) on native fauna. Through innovative field experiments and empirical modelling, this project expects to generate new knowledge in the key areas of wildlife conservation, fire ecology and invasive species management. Expected outcomes of this project include transformative insights into how threats interact to influence biodiversity and greatly enhanced capacity to manage bushfires and invasive predators. These advances should provide significant benefits, including improved conservation of threatened species, advances in ecological theory and improved capacity to predict and respond to environmental change.Read moreRead less
Movement ecology of granivores: informing fire management of savannas. This project aims to examine the decline in granivorous finches across north Australia and test the hypothesis that an increasingly nomadic lifestyle, associated with tracking grass seed availability over larger spatial scales, is the cause. The project also aims to evaluate how fire affects rangeland functioning, particularly grass diversity, to improve fire management of tropical savannas in northern Australia. This project ....Movement ecology of granivores: informing fire management of savannas. This project aims to examine the decline in granivorous finches across north Australia and test the hypothesis that an increasingly nomadic lifestyle, associated with tracking grass seed availability over larger spatial scales, is the cause. The project also aims to evaluate how fire affects rangeland functioning, particularly grass diversity, to improve fire management of tropical savannas in northern Australia. This project will provide new tools and technologies that will monitor mobile small vertebrates. Expected outcomes will improve the understanding of tropical savanna functioning and fire management.
