Inappropriate fire regimes threaten native species with extinction. The threat is higher in cleared landscapes where habitat is isolated and recolonisation unlikely. Furthermore, climate change is predicted to increase the frequency of intense bushfires. To meet the priority goals Sustainable Use of Biodiversity, and Responding to Climate Change, landscape-scale fire management is essential. We will use simulation models based on detailed biological data and fire-behaviour to explore large-scale and long-term consequences of alternate fire management policies. Our project will enable fire mosaics to be implemented that maintain biodiversity and will identify effective fire management responses to climate change, and habitat fragmentation.Read moreRead less
Management of fire-prone shrublands in Western Australia: testing the effects of frequent fire. Understanding the impacts of different fire regimes (frequency, intensity, patchiness, size of fires) on high diversity shrublands will help CALM (the land managers) develop fire management prescriptions that ensure the conservation of rare and threatened flora, and maintain biodiversity. The research will identify relationships between weather, fuel and fire behaviour that is currently lacking for s ....Management of fire-prone shrublands in Western Australia: testing the effects of frequent fire. Understanding the impacts of different fire regimes (frequency, intensity, patchiness, size of fires) on high diversity shrublands will help CALM (the land managers) develop fire management prescriptions that ensure the conservation of rare and threatened flora, and maintain biodiversity. The research will identify relationships between weather, fuel and fire behaviour that is currently lacking for shrubland vegetation types. It offers advances in our understanding of ecosystem structure and function, with applied value in fire management for conservation and asset protection. The project contributes to development of ecological theory, and provides a scientific basis for improved management of Australia's unique natural heritage.Read moreRead less
How does flow regulation affect food web linkages between juvenile and larval fish and aquatic invertebrates in a coastal river? River regulation to supply water for human demands has altered flow regimes in many Australian rivers. These changes in flow impact on native invertebrate and fish community composition. Environmental flow allocations seek to alleviate these impacts but managers are hampered by lack of data on the effects of flow on food web linkages, particularly for juvenile and lar ....How does flow regulation affect food web linkages between juvenile and larval fish and aquatic invertebrates in a coastal river? River regulation to supply water for human demands has altered flow regimes in many Australian rivers. These changes in flow impact on native invertebrate and fish community composition. Environmental flow allocations seek to alleviate these impacts but managers are hampered by lack of data on the effects of flow on food web linkages, particularly for juvenile and larval fish (JLF). We aim to compare food webs of invertebrates and JLF in six tributaries of the Hunter River, three of which are regulated, to determine how flow regulation changes trophic linkages. A flow release in one tributary will let us test the hypothesis that river regulation restricts food availability to JLF, reducing their viability, growth rates, and abundance.Read moreRead less
Identifying cost-effective reforestation approaches for biodiversity conservation and carbon sequestration in the Australian wet tropics. There is great potential for rainforest reforestation to help in the protection of Australia's tropical flora and fauna. Little is known, however, about how to reforest pasture to rainforest for the purpose of maximising the recovery of native biodiversity. We propose a unique experimental study of rainforest reforestation practices with biodiversity conservat ....Identifying cost-effective reforestation approaches for biodiversity conservation and carbon sequestration in the Australian wet tropics. There is great potential for rainforest reforestation to help in the protection of Australia's tropical flora and fauna. Little is known, however, about how to reforest pasture to rainforest for the purpose of maximising the recovery of native biodiversity. We propose a unique experimental study of rainforest reforestation practices with biodiversity conservation as a primary goal. Reforestation is currently an unlikely option for most landholders in Australia's tropics given the lack of data on the economic benefits obtainable from such efforts. Our study examines the profits obtainable through the carbon market for each reforestation approach with the goal of increasing the feasibility of rainforest reforestation in North Queensland.Read moreRead less

Integration of information from multiple disciplines is vital to answering questions like 'What governs distribution of evolutionary lineages in Australia? How and why did distributions change in the past? How might distributions change in the future?' We will develop a comprehensive network bringing together experts in geochronology, geomorphology, climatology, biogeography, palaeobiology, functional anatomy and physiology, phylogenetics, biodiversity assessment, ecosystem dynamics, and population biology and modeling. This network will provide deeper understanding of and more accurate and influential management advice for Australia's biotic resources. The public outreach program to be developed will be significant given the high profile of many participants.Read moreRead less

This project targets research priority 'An Environmentally Sustainable Australia' through the management and protection of Australia's terrestrial biodiversity, and by increasing understanding of the impact of climate change and variability at the local to regional level. By linking disparate data sets across similar climatic regions, and through direct links to management agencies, this project will enable development of a landscape conservation culture for improved conservation outcomes, and more direct information use through science-based adaptive management. Efficient use of existing data and the 'promotion of an innovation culture and economy' by linking global perspectives to local conservation needs, are hallmarks of this project.Read moreRead less

POPs are subject to a global treaty seeking to reduce and eventually eliminate these chemicals from the environment. Inhibiting the development of effective intervention strategies is a lack of knowledge regarding biological dose-response and cause-effect relationships. The proposed study will develop multiple endpoint assays to investigate these species-specific relationships and undertake a multidisciplinary risk assessment of increasing POP levels to E. superba. The research will fulfil national treaty requirements and represents an excellent opportunity to advance the field of polar and marine POP ecotoxicology. Outcomes will be critical for the sustainable management of a commercial resource and a pressured keystone species. Read moreRead less
