Introduced species are one of the greatest threats to our biodiversity and agriculture, as evidenced by the ARC’s National Research Priority: Safeguarding Australia. This project will advance Australia’s ability to protect itself from invaders by developing tools that guide cost-effective detection and response. Our project will have a direct effect on the planning and management of Hawkweed control in Victoria and New South Wales. The framework delivered will have direct application to numerous other weeds (and relevance to other pests and diseases) within and beyond Australia. Read moreRead less
Prediction and Management Strategies for Blooms of the Toxic Cyanobacterium Lyngbya majuscula in Coastal Australian Waters. Blooms of the toxic cyanobacterium Lyngbya majuscula in Australia coastal waters are resulting in severe ecological and economic impacts, including significant human health problems. What is urgently needed is the capacity to predict the onset of a Lyngbya bloom and the development of management strategies to reduce or control blooms. We have assembled a dynamic team of a ....Prediction and Management Strategies for Blooms of the Toxic Cyanobacterium Lyngbya majuscula in Coastal Australian Waters. Blooms of the toxic cyanobacterium Lyngbya majuscula in Australia coastal waters are resulting in severe ecological and economic impacts, including significant human health problems. What is urgently needed is the capacity to predict the onset of a Lyngbya bloom and the development of management strategies to reduce or control blooms. We have assembled a dynamic team of active and experienced researchers using various state-of-the-art technologies to elucidate the key factors contributing to Lyngbya blooms and have industry partners willing to implement large scale testing of various controls. We have a unique opportunity to potentially solve a pressing environmental problem.Read moreRead less
Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia ....Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia from invasive diseases. There is an urgency to undertake our research because global environmental change and increasing movements of people (particularly military personnel) from overseas regions where these diseases are endemic is increasing the vulnerability of northern Australia to the (re)establishment of mosquito borne diseases.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
Ecology and evolution in dynamic systems: a new approach to conserving Australian biodiversity. Australia has different ecosystems and different species than the rest of the world, and we need a different approach to conserve and manage our unique animals. This project will develop a new, specifically Australian-oriented approach to conservation biology.
How do characteristics of seeds and landscape heterogeneity determine plant spread in new environments? Climate change and exotic invasions are among the greatest threats to Australia's, and the world's, biodiversity. Under a rapidly changing climate many Australian plant species will have to spread across a fragmented landscape to persist. In order to contain or eradicate invasive plant species we need to know how they will spread in novel landscapes. We will develop models which will be used f ....How do characteristics of seeds and landscape heterogeneity determine plant spread in new environments? Climate change and exotic invasions are among the greatest threats to Australia's, and the world's, biodiversity. Under a rapidly changing climate many Australian plant species will have to spread across a fragmented landscape to persist. In order to contain or eradicate invasive plant species we need to know how they will spread in novel landscapes. We will develop models which will be used for invasive plants to predict ecological and evolutionary responses to novel landscapes and novel dispersers and for native plants to predict their spread in to fragmented landscapes. These models can be used to prioritise management actions for species of most conservation concern, and predict how far and fast invasive species will spread.Read moreRead less
The roles of invasive ants in urban ecosystem dynamics and restoration. The potential impacts of invasive ants are recognised worldwide, and we know that invasive ant species are already present in heavily disturbed areas in southern Australia, particularly in urban settlements. However, as yet, we have very little information on the actual and potential impacts of invasive ants on ecosystem processes. Urban bushland is seen as an important conservation and amenity resource, and there are incre ....The roles of invasive ants in urban ecosystem dynamics and restoration. The potential impacts of invasive ants are recognised worldwide, and we know that invasive ant species are already present in heavily disturbed areas in southern Australia, particularly in urban settlements. However, as yet, we have very little information on the actual and potential impacts of invasive ants on ecosystem processes. Urban bushland is seen as an important conservation and amenity resource, and there are increasing efforts to manage and restore these areas. This project aims to elucidate the likely impact of invasive ants on the maintenance and restoration of urban bushland, and hence provide guidance as to whether management and restoration needs to include invasive ant control.

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
The regeneration niche of invasive plants: managing the weed-shaped hole. In Australia $20 million was spent on weed control in natural areas in 2001-02 and is indicative of the level of funding for weed control programs each year. An understanding of how current weed control programs affect the regeneration of weeds in the system will give us novel insights into the persistence of weed populations despite sustained investment in control. Environmental weeds threaten biodiversity and ecosystem ....The regeneration niche of invasive plants: managing the weed-shaped hole. In Australia $20 million was spent on weed control in natural areas in 2001-02 and is indicative of the level of funding for weed control programs each year. An understanding of how current weed control programs affect the regeneration of weeds in the system will give us novel insights into the persistence of weed populations despite sustained investment in control. Environmental weeds threaten biodiversity and ecosystem function in unique Australian communities, better management of weeds will have conservation, ecosystem service provision and amenity values nationally. This project highlights the importance of understanding the weed regeneration niche for successful long-term and sustainable control.Read moreRead less
