Optimal environmental monitoring under severe uncertainty. Environmental monitoring is a type of quality control that informs managers about the health of the environment and about how well their management systems are performing. Because it is a critical, but expensive, component of sustainable management, it is important to ensure value for resources spent on monitoring and that environmental impacts will be detected if they are occurring. We argue that current approaches to environmental mana ....Optimal environmental monitoring under severe uncertainty. Environmental monitoring is a type of quality control that informs managers about the health of the environment and about how well their management systems are performing. Because it is a critical, but expensive, component of sustainable management, it is important to ensure value for resources spent on monitoring and that environmental impacts will be detected if they are occurring. We argue that current approaches to environmental management ensure neither efficiency nor environmental security. The aim of the project is to develop theories and techniques to make monitoring both cost effective and reliable, thereby providing monetary savings and better environmental outcomes.Read moreRead less
Improved methods for predicting species' distributions under environmental change. Understanding the impacts of climate change and invasive species on the distribution and persistence of species is an issue of global and national significance and concern. This project will provide tools essential for the effective management of Australia's ecosystems by delivering clear guidelines and practical methods that will substantially improve the modelling of future species distributions.
Developing tools for assessing ecological performance of marine protected areas. Marine Protected Areas (MPAs) are rapidly being established around Australia as a device to conserve marine biodiversity. Their ability to sustain animal and plant populations depends critically on the ability of populations to replenish themselves, but we have no ready way of assessing replenishment, relying instead on simple counts of animals and plants within MPAs as a measure of their success. We propose a new ....Developing tools for assessing ecological performance of marine protected areas. Marine Protected Areas (MPAs) are rapidly being established around Australia as a device to conserve marine biodiversity. Their ability to sustain animal and plant populations depends critically on the ability of populations to replenish themselves, but we have no ready way of assessing replenishment, relying instead on simple counts of animals and plants within MPAs as a measure of their success. We propose a new measure, using relationships between adult stocks and recruitment, as a way of assessing the long-term success of MPAs. We will test this measure using comparisons among marine national parks that were established recently in Victoria.Read moreRead less
Synthesising prior information for ecological research and management. While using existing information to design studies and compare results, ecologists rarely use existing information in their analyses. We will combine the results of previous ecological studies to summarise the existing information. We will test how well the traits of plants and animals can be predicted from previous research, and the benefit of this existing information for environmental management. By taking advantage of the ....Synthesising prior information for ecological research and management. While using existing information to design studies and compare results, ecologists rarely use existing information in their analyses. We will combine the results of previous ecological studies to summarise the existing information. We will test how well the traits of plants and animals can be predicted from previous research, and the benefit of this existing information for environmental management. By taking advantage of the wealth of previous ecological research, our project can save time and money for ecological research by scientists and environmental management by federal and state agencies. This will fundamentally change the way that ecology is conducted.Read moreRead less
Optimal management of threatened amphibian metapopulations in urbanising landscapes. This project will enable the identification of optimal management strategies for many species threatened by the loss and fragmentation of their habitat, both in Australia and internationally. Our research will contribute to the recovery of the endangered Growling Grass Frog, and drive the conservation of wetland biodiversity on the fringe of Australia's fastest growing city. Both the methods and specific recomme ....Optimal management of threatened amphibian metapopulations in urbanising landscapes. This project will enable the identification of optimal management strategies for many species threatened by the loss and fragmentation of their habitat, both in Australia and internationally. Our research will contribute to the recovery of the endangered Growling Grass Frog, and drive the conservation of wetland biodiversity on the fringe of Australia's fastest growing city. Both the methods and specific recommendations for management that we develop will contribute to the goal of an environmentally-sustainable Australia. This project will expand Australia's capacity to solve conservation problems, and will promote biological diversity in urban environments, to the benefit of their human inhabitants.Read moreRead less
General theory for eradicating multiple invasive species from threatened island ecosystems. Invasive species threaten many of Australia's unique flora and fauna. Our island ecosystems have evolved in the absence of mammalian predators, and are therefore particularly vulnerable. When both cats and rats invade an island, they can quickly decimate the populations of native species, particularly seabirds, and threaten them with extinction. Unfortunately, poorly planned eradication of these invasive ....General theory for eradicating multiple invasive species from threatened island ecosystems. Invasive species threaten many of Australia's unique flora and fauna. Our island ecosystems have evolved in the absence of mammalian predators, and are therefore particularly vulnerable. When both cats and rats invade an island, they can quickly decimate the populations of native species, particularly seabirds, and threaten them with extinction. Unfortunately, poorly planned eradication of these invasive species can destabilise the complex island ecosystems, further endangering the native species. The results of this project will help conservation managers to plan eradication strategies that cost-effectively eradicate populations of two introduced species, without threatening native wildlife.Read moreRead less
Modelling species distributions for a changing world.

Robust prediction and decision strategies for managing extinction risks under climate change. Climate change is a principal threat to biodiversity and ecosystem health. The loss of ecosystem services from loss of species and ecosystem change may have serious social and economic repercussions. Unreliable predictions of climate change impacts and inefficient adaptation decisions result in wasted public resources and unnecessary loss of natural assets. In addition to direct benefits of efficient ad ....Robust prediction and decision strategies for managing extinction risks under climate change. Climate change is a principal threat to biodiversity and ecosystem health. The loss of ecosystem services from loss of species and ecosystem change may have serious social and economic repercussions. Unreliable predictions of climate change impacts and inefficient adaptation decisions result in wasted public resources and unnecessary loss of natural assets. In addition to direct benefits of efficient adaptation strategies for case-study ecosystems, techniques arising from this research will improve the way we respond to uncertain, but potentially catastrophic consequences of climate change. Bringing state-of-the-art modelling and formal decision methods to climate change adaptation is a central aim of this research.Read moreRead less
Genes to phenotype: Exploiting the marsupial model. This research will exploit one of Australia's finest natural resources, its marsupial fauna. The features of marsupial reproduction and development provide a unique opportunity to answer fundamental biological questions. This research will show how the minor differences in key developmental genes that have arisen in their 100 million year isolation give rise to the characteristic differences in developmental timing and reproduction between mar ....Genes to phenotype: Exploiting the marsupial model. This research will exploit one of Australia's finest natural resources, its marsupial fauna. The features of marsupial reproduction and development provide a unique opportunity to answer fundamental biological questions. This research will show how the minor differences in key developmental genes that have arisen in their 100 million year isolation give rise to the characteristic differences in developmental timing and reproduction between marsupials and other mammals. The focus on reproduction and development will also provide invaluable knowledge to underpin efforts to conserve our endangered species and to control those that are overabundant.Read moreRead less
Vegetation change in coastal Parks and Reserves: risk assessment and management of woody invaders. Coastal heath ecosystems contain some of the highest diversity of plant species for any vegetation type within temperate Australia. These communities exist within and outside the Reserve system, but even those within Parks and Reserves may be undergoing rapid change in structure and composition as a result of invading environmental weeds, resulting in a significant loss of biological diversity. As ....Vegetation change in coastal Parks and Reserves: risk assessment and management of woody invaders. Coastal heath ecosystems contain some of the highest diversity of plant species for any vegetation type within temperate Australia. These communities exist within and outside the Reserve system, but even those within Parks and Reserves may be undergoing rapid change in structure and composition as a result of invading environmental weeds, resulting in a significant loss of biological diversity. As agriculture, tourism and other developments place increasing pressure on these diminishing ecosystems, the maintenance of their biodiversity takes on increasing importance. This project will identify threatening processes and devise cost-effective, practicable management strategies in a context of competing stakeholder interests.Read moreRead less
