The roles of stress and immunocompetence in biological invasions. Invasive species pose a major threat to biodiversity worldwide; and within Australia, cane toads are widely viewed as one of the biggest such problems. Building on recent studies that reveal weakened immune systems in invasion-front toads, this project will provide a comprehensive understanding of immune responses in cane toads and native frogs, with the aim of exploiting the toads' immunocompromised state to develop new and more ....The roles of stress and immunocompetence in biological invasions. Invasive species pose a major threat to biodiversity worldwide; and within Australia, cane toads are widely viewed as one of the biggest such problems. Building on recent studies that reveal weakened immune systems in invasion-front toads, this project will provide a comprehensive understanding of immune responses in cane toads and native frogs, with the aim of exploiting the toads' immunocompromised state to develop new and more effective control measures. The project will develop a new paradigm about the roles of stress and immunity in biological invasion, applicable to the control of other invasive species and to understanding processes at work when environmental changes force species to shift their ranges.Read moreRead less
Applying search theory for eradicating invasive species. Invasive species have major economic and environmental impacts in Australia and are a major cause of extinctions worldwide. Monitoring is crucial for the timely control of invasive species in sensitive environments. Early detection increases the probability of eradication and increased accuracy in detection reduces the impact of control programs on non-target species. Efficient monitoring also is crucial in determining whether eradication ....Applying search theory for eradicating invasive species. Invasive species have major economic and environmental impacts in Australia and are a major cause of extinctions worldwide. Monitoring is crucial for the timely control of invasive species in sensitive environments. Early detection increases the probability of eradication and increased accuracy in detection reduces the impact of control programs on non-target species. Efficient monitoring also is crucial in determining whether eradication has succeeded. Search Theory has been applied for over 60 years in a wide range of non-biological monitoring problems, resulting in large increases in target detection rates. Gains of a similar magnitude in invasive species detection would greatly enhance Australia's capacity to manage these threats.Read moreRead less
Naturalisation to invasion: how do naturalised plants become successful invaders? Invasive plants have enormous environmental, economic and social impacts in Australia, significantly affecting biodiversity and ecosystem processes, agricultural productivity and recreational amenity. This research will contribute substantially to our understanding of the processes that underlie the transition from naturalised to invasive for introduced plants. By identifying the key factors enabling naturalised pl ....Naturalisation to invasion: how do naturalised plants become successful invaders? Invasive plants have enormous environmental, economic and social impacts in Australia, significantly affecting biodiversity and ecosystem processes, agricultural productivity and recreational amenity. This research will contribute substantially to our understanding of the processes that underlie the transition from naturalised to invasive for introduced plants. By identifying the key factors enabling naturalised plant species to become invasive pests, this research will enable plant species most likely to threaten Australia's biodiversity and agricultural productivity to be identified and prioritized for screening and eradication.Read moreRead less
A multispecies approach to managing feral animals in tropical savanna landscapes. Controlling invasive species is important for maintaining healthy landscapes. Often, multiple invasive species occupy a landscape and simultaneous management of them is required. Our innovative management tool will allow land managers to develop and implement control strategies for environmentally invasive species in Northern Australia and globally.
Understanding and managing resistance to the amphibian chytrid fungus Batrachochytrium dendrobatidis in Australian tropical rainforest frogs. The fungal disease chytridiomycosis can infect at least 48 Australian native frog species and is listed as a threatening process under the federal Environment Protection and Biodiversity Conservation Act. It caused catastrophic declines in 12 frog species in Queensland between 1979 and 1994, and is probably responsible for continuing declines in many more ....Understanding and managing resistance to the amphibian chytrid fungus Batrachochytrium dendrobatidis in Australian tropical rainforest frogs. The fungal disease chytridiomycosis can infect at least 48 Australian native frog species and is listed as a threatening process under the federal Environment Protection and Biodiversity Conservation Act. It caused catastrophic declines in 12 frog species in Queensland between 1979 and 1994, and is probably responsible for continuing declines in many more species in most states. A few species and populations have recovered following declines, indicating that they have increased their resistance to the disease. Understanding these increases in resistance should allow us to develop ways to control the disease in other species, helping to protect Australia against this invasive and highly destructive disease.Read moreRead less
Understanding and predicting the success of invasive plants: a leaf carbon strategy approach. Invasion of plant communities by exotic plants is a significant threat to biodiversity and ecosystem processes globally. This proposal seeks to understand strategies of invasive plants in novel environments both now and under predicted future conditions, using the framework of leaf carbon strategies. Comparative and experimental approaches will be used to understand leaf trait relationships of invasive ....Understanding and predicting the success of invasive plants: a leaf carbon strategy approach. Invasion of plant communities by exotic plants is a significant threat to biodiversity and ecosystem processes globally. This proposal seeks to understand strategies of invasive plants in novel environments both now and under predicted future conditions, using the framework of leaf carbon strategies. Comparative and experimental approaches will be used to understand leaf trait relationships of invasive compared with native species. This will contribute substantially to our understanding of global plant functional relationships, thereby enabling better prediction of potential invaders. The resulting data will also provide critical input for models of plant, ecosystem and biosphere responses to global change incorporating invasion dynamics.Read moreRead less

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
Disease in endangered species: The importance of multiple-host infection and spatial structure. Pathogens are increasingly recognised as threats to endangered species. Managing such threats requires models to assess alternative strategies. Most current models deal with a single host and single pathogen, without spatial structure, although multiple-host pathogens pose the greatest conservation threats. This project develops a new generation of spatially-structured multiple-host models, and applie ....Disease in endangered species: The importance of multiple-host infection and spatial structure. Pathogens are increasingly recognised as threats to endangered species. Managing such threats requires models to assess alternative strategies. Most current models deal with a single host and single pathogen, without spatial structure, although multiple-host pathogens pose the greatest conservation threats. This project develops a new generation of spatially-structured multiple-host models, and applies them to two case studies. The first is the chytrid fungus that is thought to have lead to widespread declines and extinctions of frogs in Australia and overseas. The second is birdpox and malaria that have led to the extinction and endangerment of much of Hawaii's endemic avifauna.Read moreRead less
