Macroecology and phylogeny: the effects of evolutionary history on rarity and extinction risk in Australian vertebrates. We will combine ecological and phylogenetic analysis of Australian vertebrates to show how abundance and geographic range in living species has been shaped by the historical processes of speciation, transformations of range and abundance in relation to species age, and selective extinction. Our analysis will throw new light on the processes that have generated species diversit ....Macroecology and phylogeny: the effects of evolutionary history on rarity and extinction risk in Australian vertebrates. We will combine ecological and phylogenetic analysis of Australian vertebrates to show how abundance and geographic range in living species has been shaped by the historical processes of speciation, transformations of range and abundance in relation to species age, and selective extinction. Our analysis will throw new light on the processes that have generated species diversity in Australian vertebrates. We will also gain new understanding of the causes of rarity and vulnerability to extinction among living species, which will result in better identification and management of species at risk of extinction.Read moreRead less
Extrinsic threats and biological predisposition in animal extinction and rediscovery. A global extinction crisis looms, and Australia has a shocking record, especially of mammal extinctions. The results of this project to find how different threats affect each species will lead to management that focusses on species- and region-specific causes. This will help to prevent further extinctions of Australian mammals and other fauna. Many people hope that species of particular importance to us such as ....Extrinsic threats and biological predisposition in animal extinction and rediscovery. A global extinction crisis looms, and Australia has a shocking record, especially of mammal extinctions. The results of this project to find how different threats affect each species will lead to management that focusses on species- and region-specific causes. This will help to prevent further extinctions of Australian mammals and other fauna. Many people hope that species of particular importance to us such as the thylacine have defied extinction, and will be rediscovered. This project will test which predictive factors can increase the chance of species rediscovery, and help management agencies plan for the expected number of future rediscoveries.Read moreRead less
The preservation and management of Koala genetic diversity using reproductive biotechnology and molecular genetics: A model for endangered Australian marsupials. Assisted breeding technology will provide a new paradigm for solving problems associated with the preservation and management of captive and wild Koala populations.

Assisted breeding technology will provide a new paradigm for solving problems associated with the preservation and management of captive and wild Koala populations. This project aims to improve methods of koala sperm cryopreservation and its subsequent use in artificial insemination and to establish a functional frozen sperm bank screened for the most prevalent pathogens. Important outcomes will include (1) a reliable, cost effective and disease free approach to the transfer of Koala genetic material into international and national zoos; (2) a technique for the management of free-range genetically restricted Koala populations and (3) successful cryostorage of Koala spermatozoa for the long-term maintenance of genetic potential.Read moreRead less
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
Network structure, connectivity and wildlife disease. Emerging infectious diseases of wildlife pose threats to human health (75% of human emerging diseases are zoonotic). They also threaten biodiversity and livestock. Changes in connectivity between wildlife individuals and populations are occurring because of human activities, including globalisation, climate change and habitat destruction. Understanding how these changes in connectivity affect wildlife disease dynamics is crucial for the deve ....Network structure, connectivity and wildlife disease. Emerging infectious diseases of wildlife pose threats to human health (75% of human emerging diseases are zoonotic). They also threaten biodiversity and livestock. Changes in connectivity between wildlife individuals and populations are occurring because of human activities, including globalisation, climate change and habitat destruction. Understanding how these changes in connectivity affect wildlife disease dynamics is crucial for the development of better strategies to manage their impacts. The project will also build Australia's wider capacity to manage outbreaks of infectious diseases.Read moreRead less
Predicting metapopulation dynamics with multiple patch states. Classical theory allows metapopulations to have subpopulations in one of two states, occupied or unoccupied. However, patches may have their own dynamic created by ecological succession or disturbance processes such as grazing. We will develop new theory incorporating patch dynamics, and test the theory on a spatially explicit metapopulation in the real world, the mound spring invertebrates of the Great Artesian Basin. We will use th ....Predicting metapopulation dynamics with multiple patch states. Classical theory allows metapopulations to have subpopulations in one of two states, occupied or unoccupied. However, patches may have their own dynamic created by ecological succession or disturbance processes such as grazing. We will develop new theory incorporating patch dynamics, and test the theory on a spatially explicit metapopulation in the real world, the mound spring invertebrates of the Great Artesian Basin. We will use the theory to forecast the risk of extinction for these endemic species, and develop methods to quantify the statistical power of monitoring for environmental trends.Read moreRead less
Landscape-scale monitoring and adaptive management of woodland birds in the Mt Lofty Ranges. Despite the fundamental role of scientific monitoring in nature conservation, its research importance and potential is widely neglected. There is an urgent need to improve quantitative rigour, particularly to ensure adequate statistical power is achieved when monitoring at a landscape scale. We will apply new analytical tools to the problem of devising a powerful and flexible monitoring regime for a high ....Landscape-scale monitoring and adaptive management of woodland birds in the Mt Lofty Ranges. Despite the fundamental role of scientific monitoring in nature conservation, its research importance and potential is widely neglected. There is an urgent need to improve quantitative rigour, particularly to ensure adequate statistical power is achieved when monitoring at a landscape scale. We will apply new analytical tools to the problem of devising a powerful and flexible monitoring regime for a highly threatened woodland bird community in South Australia. Monitoring will be embedded within a decision-making framework with explicit links to local management agencies. Results will be broadly applicable across agricultural areas of Australia, where bird assemblages are in general decline.Read moreRead less
Predicting the Impact of Damming on the Endangered Mary River Turtle. Little is known about the effects of inland river alteration on the ecology of freshwater turtles, where river damming results in dramatic changes in river physical, chemical and biological characteristics. In Australia there are 446 large dams, necessary for hydro-electric power, navigation, flood control, irrigation and drinking water. Many of these rivers are inhabited by freshwater turtles, endemic to Australia, and this ....Predicting the Impact of Damming on the Endangered Mary River Turtle. Little is known about the effects of inland river alteration on the ecology of freshwater turtles, where river damming results in dramatic changes in river physical, chemical and biological characteristics. In Australia there are 446 large dams, necessary for hydro-electric power, navigation, flood control, irrigation and drinking water. Many of these rivers are inhabited by freshwater turtles, endemic to Australia, and this project will assess the impact of changes in habitat quality on the endangered Mary River Turtle (Elusor macrurus). The study comes at a timely opportunity, as proposed river damming will substantially alter the turtles' habitat, and its survival potential remains unknown.Read moreRead less
