Proposed management options such as allowing seawater incursion and the construction of a weir to impede freshwater flows are based ....Establishing baseline ecological conditions for the Lower Lakes, South Australia: the applications of palaeoecology to sustainable resource management. The Lower Lakes of the Murray River are in a critical ecological state due to record low water levels. Management of these lakes needs to integrate water security demands with maintaining healthy ecosystem functions. Proposed management options such as allowing seawater incursion and the construction of a weir to impede freshwater flows are based on assumptions about what the Lakes were like naturally (pre-European). This study will reconstruct environmental variability within the Lower Lakes over the past 7000 years, concentrating on salinity to document the extent of marine incursion, and pH to examine the impacts of acid sulphate release from exposed sediments during low flow events.

A unified approach for estimating coastal flood risk. The project aims to develop a unified approach to quantifying flood risk. Because flooding is caused by multiple mechanisms such as extreme rainfall, storm surge and astronomical tide, accurately estimating flood levels in the Australian coastal zone is challenging. By quantifying flood risk in terms of these mechanisms, the project is expected to provide reliable flood risk estimates for both historical settings and future climate scenarios. ....A unified approach for estimating coastal flood risk. The project aims to develop a unified approach to quantifying flood risk. Because flooding is caused by multiple mechanisms such as extreme rainfall, storm surge and astronomical tide, accurately estimating flood levels in the Australian coastal zone is challenging. By quantifying flood risk in terms of these mechanisms, the project is expected to provide reliable flood risk estimates for both historical settings and future climate scenarios. The improved estimation should enable Australian water agencies and policy-makers to effectively design defence infrastructure (e.g. drainage systems) and urban planning policies to adapt to future flood risk.Read moreRead less

This project aims to address the sourcing of native seed for ecological restoration under global change. The great demand for native seed to deliver ecological restoration provides a clear need and responsibility to use this seed as efficiently as possible. This project expects to develop detailed new knowledge that links plant and environmental genomics, plant physiology, seed and soil biology in embedded experiments at post-mining rehabilitation sites. Expected outcomes include clear industry guidelines that refine seed sourcing strategies for ecological restoration for current and future climates. This should provide significant benefits for improved ecological restoration outcomes when using native seed today and into the future.Read moreRead less
Development of a vaccine to protect koalas against koala retrovirus (KoRV). This project aims to develop a vaccine against koala retrovirus (KoRV) to arrest the increasing loss of animals due to this infection. Along with Chlamydia, KoRV threatens the long-term survival of the koala. KoRV infects over 95 per cent of Australia’s koalas and has been strongly linked to lymphoma and leukemia. Although quarantine and antiretroviral drug treatment are possible control measures, they are impractical in ....Development of a vaccine to protect koalas against koala retrovirus (KoRV). This project aims to develop a vaccine against koala retrovirus (KoRV) to arrest the increasing loss of animals due to this infection. Along with Chlamydia, KoRV threatens the long-term survival of the koala. KoRV infects over 95 per cent of Australia’s koalas and has been strongly linked to lymphoma and leukemia. Although quarantine and antiretroviral drug treatment are possible control measures, they are impractical in the wild, leaving vaccination as the only realistic option. This is valuable for both wild and captive koalas; zoos report high animal losses due to KoRV-associated lymphoma. The main outcome will be a KoRV vaccine which can be combined with a Chlamydia vaccine which is being developed in parallel.Read moreRead less

The impact of severe bushfires on the ecology, demography and genetics of frogs in the Victorian Kinglake region. The February 2009 bushfires in Victoria devastated many communities, and also had a profound impact on wildlife species. This research is aimed at measuring the impact of these fires on frogs in the Kinglake region. It will provide a range of national benefits, including a better understanding of the effects of wildfire on native species and their habitats, information to help plan c ....The impact of severe bushfires on the ecology, demography and genetics of frogs in the Victorian Kinglake region. The February 2009 bushfires in Victoria devastated many communities, and also had a profound impact on wildlife species. This research is aimed at measuring the impact of these fires on frogs in the Kinglake region. It will provide a range of national benefits, including a better understanding of the effects of wildfire on native species and their habitats, information to help plan conservation efforts for frogs, and a vital connection with local landowners; some of whom lost their homes in the fires but were still concerned about the wellbeing of frogs in the area. Australia is a fire-prone country, and this project will help develop responses to the threats posed by the expected increase in the frequency and intensity of fires in southern Australia.Read moreRead less
