Establishment of the Australian Cane Toad Genome Program. The Cane Toad is one of Australia's greatest environmental menaces, and is in the top 100 of the "World's Worst invader species". Over a billion toads infest Northern Australia, and they will soon invade WA and move further into NSW. Their poisons and voracious appetite could make many native mammals, birds and reptiles extinct. The only possibility to eradicate the Toad is by biological control, but there is no known control agent. We wi ....Establishment of the Australian Cane Toad Genome Program. The Cane Toad is one of Australia's greatest environmental menaces, and is in the top 100 of the "World's Worst invader species". Over a billion toads infest Northern Australia, and they will soon invade WA and move further into NSW. Their poisons and voracious appetite could make many native mammals, birds and reptiles extinct. The only possibility to eradicate the Toad is by biological control, but there is no known control agent. We will identify the 'Toad's Achilles' heel' against which control agents can be developed. We can do this by identifying every Toad gene. This project forms the first step to this goal by establishing the Australian Cane Toad Genome Program. Toad control will help preserve Australia's unique natural heritage.Read moreRead less
Population Genetics of Fungal Pathogens that Threaten the Biosecurity of Australia's Eucalypts. Many new pathogens and diseases are emerging on exotic eucalypt plantations throughout the world. These emerging diseases pose a threat to native eucalypt forests and plantations in Australia. Vigilant quarantine measures are necessary to prevent the introduction of potentially devastating pathogens into Australia. However, incursions do occur and there is a great need to study these pathogens now, ....Population Genetics of Fungal Pathogens that Threaten the Biosecurity of Australia's Eucalypts. Many new pathogens and diseases are emerging on exotic eucalypt plantations throughout the world. These emerging diseases pose a threat to native eucalypt forests and plantations in Australia. Vigilant quarantine measures are necessary to prevent the introduction of potentially devastating pathogens into Australia. However, incursions do occur and there is a great need to study these pathogens now, before they enter Australia. By studying the population genetics of pathogens, their evolutionary potential can be estimated and with that the extent of the risk they pose to native and planted eucalypts in Australia can be determined.Read moreRead less
Fungal pathogens threatening the sub-tropical eucalypt plantation industry in Australia. Eucalypt plantations in Australia are at risk from both native pathogens and those that have emerged on exotic eucalypt plantations and been introduced to Australia. Most of the serious pathogens of exotic plantations have emerged in the sub-tropics in climates very similar to those in Queensland. It is not known if these pathogens have already been introduced to Australia; however, increased movement of ger ....Fungal pathogens threatening the sub-tropical eucalypt plantation industry in Australia. Eucalypt plantations in Australia are at risk from both native pathogens and those that have emerged on exotic eucalypt plantations and been introduced to Australia. Most of the serious pathogens of exotic plantations have emerged in the sub-tropics in climates very similar to those in Queensland. It is not known if these pathogens have already been introduced to Australia; however, increased movement of germplasm and forest products increases the risk of introducing new eucalypt pathogens. This project will involve a detailed examination of pathogens present on eucalypts in Queensland. Studies of the diversity of pathogens and determination of their reproductive mode and their pathogenicity will enable for detailed risk assessments. Assessment of genetic trials for disease incidence will provide valuable information for future selections and breeding.Read moreRead less
Colour vision in birds: consequences to fatal collisions with wind farms. Wind-farms represent a key component of sustainable energy generation world-wide. However, many birds die as a result of collisions with wind-farms, posing an unsolved and controversial conservation issue. The proliferation of wind-farms in Australia will exacerbate the problem. Birds rely on vision to negotiate static and moving objects. Wind-farms, currently coloured to meet human aesthetic criteria, may be 'invisible' t ....Colour vision in birds: consequences to fatal collisions with wind farms. Wind-farms represent a key component of sustainable energy generation world-wide. However, many birds die as a result of collisions with wind-farms, posing an unsolved and controversial conservation issue. The proliferation of wind-farms in Australia will exacerbate the problem. Birds rely on vision to negotiate static and moving objects. Wind-farms, currently coloured to meet human aesthetic criteria, may be 'invisible' to birds since they see colours differently from humans. We will determine bird spectral sensitivities and compare them to the spectral reflectance of wind-farms. We will then develop modifications improving the visibility of wind-farms to birds, thereby reducing fatalities.Read moreRead less
Conservation of the threatened western ringtail possum, Pseudocheirus occidentalis: Is translocation a solution? The western ringtail possum, Pseudocheirus occidentalis, is recognised both nationally and internationally as a threatened species. Control of introduced predators, specifically the fox and feral cat, has been central to the success of threatened fauna conservation in Western Australia.

The western ringtail possum, Pseudocheirus occidentalis, is recognised both nationally and internationally as a threatened species. Control of introduced predators, specifically the fox and feral cat, has been central to the success of threatened fauna conservation in Western Australia. However, it is now critical to demonstrate that translocation can result in sustained fauna recovery. This program aims to determine whether translocating displaced possums to protected habitat is a viable conservation management strategy. The project will assess the importance of introduced predator control, predator interactions, competition with the common brushtail possum and disease on the survival of translocated western ringtail possums.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.

Ancient DNA as a tool to study Australia's paleome: exploring climatic change, past biodiversity, extinctions and long-term survival of DNA. Restoration of Australian ecosystems can only occur if we know what plants, animals and insects used to live in the area before 'pest' species were introduced. This project will use ancient DNA obtained from 'poo' and cave sediments, that is thousands of years old, to discover what species used to live where and when. The ancient DNA profiles of past ecosys ....Ancient DNA as a tool to study Australia's paleome: exploring climatic change, past biodiversity, extinctions and long-term survival of DNA. Restoration of Australian ecosystems can only occur if we know what plants, animals and insects used to live in the area before 'pest' species were introduced. This project will use ancient DNA obtained from 'poo' and cave sediments, that is thousands of years old, to discover what species used to live where and when. The ancient DNA profiles of past ecosystems will allow us to make better decisions when trying to establish sustainable and 'natural' mainland and island sanctuaries. Ancient DNA is well preserved in some dry environments; this project will assess DNA preservation from sites all across Australia and use the DNA sequences to discover information about extinct animals and how past climate changes effected the native biota.Read moreRead less

Exploration of the deep-sea with the modern technologies to be developed by Deep-Downunder is a first for Australia. We aim to explore and discover life at depths from 50-3000m off The Great Barrier Reef, around the seamounts of Lord Howe Island and Tasmania and in the deep canyons of WA and SA. We expect to discover new species, hope for a glimpse of giant squid at home and will answer specific questions on ....Deep Downunder: designing a deep-sea exploration and discovery capability for Australia. Exploration of the deep-sea with the modern technologies to be developed by Deep-Downunder is a first for Australia. We aim to explore and discover life at depths from 50-3000m off The Great Barrier Reef, around the seamounts of Lord Howe Island and Tasmania and in the deep canyons of WA and SA. We expect to discover new species, hope for a glimpse of giant squid at home and will answer specific questions on Australia's ocean biology, fisheries and biotechnology never before approachable. To be effective guardians of Australian waters we must learn what lies in the depths we can't see from a boat.Read moreRead less
Inbreeding: what are the reproductive costs and how are they avoided? Inbreeding in animal populations will undoubtedly become more prevalent in the face of increased habitat fragmentation brought on by human activities and climate change.

Inbreeding in animal populations will undoubtedly become more prevalent in the face of increased habitat fragmentation brought on by human activities and climate change. By increasing our understanding of how inbreeding influences reproductive traits, my research will be directly applicable to conservation programs, specifically by providing insights into how Australia's rich biodiversity will respond to climate change and variability. This project also addresses critical issues in evolutionary biology, thereby contributing towards Australia's reputation as a world leader in this field. Australian science will further benefit through international collaborations and from the training of young scientists.Read moreRead less
Effects of ants and ant-mediated dispersal on speciation rates, biogeography and diversity of angiosperms. This work seeks to improve our general understanding of longstanding questions in ecology in evolution, namely what are the processes that have allowed some groups to become diverse and others not, why does dispersal mode vary with geography, and how do speciation and extinction vary across space, time and taxon? In answering these questions, we will address some of the most fundamental que ....Effects of ants and ant-mediated dispersal on speciation rates, biogeography and diversity of angiosperms. This work seeks to improve our general understanding of longstanding questions in ecology in evolution, namely what are the processes that have allowed some groups to become diverse and others not, why does dispersal mode vary with geography, and how do speciation and extinction vary across space, time and taxon? In answering these questions, we will address some of the most fundamental questions in conservation, including what are the factors that make species geographically rare, which species are most at risk for climate change, and what are the factors that have led habitats like the Kwongan Heath and Fynbos to be so exceptionally biodiverse.Read moreRead less
