Development and implementation of biodiversity information for sustainable management of South Australian groundwater. Clean potable water is one of the most important resources for human health and a successful economy. Increasingly, subterranean aquifers are used for storage and recovery of water. These aquifers contain dynamic ecosystems, but little is known about species composition or about the importance of the presence of various species for water quality. We will use the latest laborator ....Development and implementation of biodiversity information for sustainable management of South Australian groundwater. Clean potable water is one of the most important resources for human health and a successful economy. Increasingly, subterranean aquifers are used for storage and recovery of water. These aquifers contain dynamic ecosystems, but little is known about species composition or about the importance of the presence of various species for water quality. We will use the latest laboratory techniques and DNA identification methods to provide a template for determining ground water diversity and food web dynamics throughout Australia. This project will lead to a better understanding of how to manage ground water in a sustainable manner.Read moreRead less
Solving the water crisis in Australian cities and towns with options contracts between urban and rural water users. We will equip water resource managers with a powerful and effective tool for the allocation of water resources between rural and urban sectors. The importance of this bridge cannot be understated. To date urban centres have endured stringent water restrictions to manage dwindling urban suppliers, while ignoring the potential benefits of purchasing water from the irrigated agricul ....Solving the water crisis in Australian cities and towns with options contracts between urban and rural water users. We will equip water resource managers with a powerful and effective tool for the allocation of water resources between rural and urban sectors. The importance of this bridge cannot be understated. To date urban centres have endured stringent water restrictions to manage dwindling urban suppliers, while ignoring the potential benefits of purchasing water from the irrigated agriculture sector. Furthermore, rural communities have suffered hardship due to restricted agricultural production during times of drought. This research proposal represents an exciting solution to both problems and offers the tantalising prospect of water shortages in our capital cities and towns becoming distant memories.Read moreRead less
The ancient symbiosis of crayfish and temnocephalan flatworms in Australian freshwaters investigated using molecules, morphology and biogeography. Freshwater parastacid crayfish are widespread and diverse in Australia's freshwaters. Associated with them (living on external surfaces) since their origins on Gondwana are very many species of temnocephalan flatworms. We will elucidate the molecular, morphological and biogeographic history of this association which appears to be ancient and specific. ....The ancient symbiosis of crayfish and temnocephalan flatworms in Australian freshwaters investigated using molecules, morphology and biogeography. Freshwater parastacid crayfish are widespread and diverse in Australia's freshwaters. Associated with them (living on external surfaces) since their origins on Gondwana are very many species of temnocephalan flatworms. We will elucidate the molecular, morphological and biogeographic history of this association which appears to be ancient and specific. The study will shed light on Australia's biological links with New Zealand and South America. It will also use the association between crayfish and temnocephalans as a model to investigate general features of symbioses, including molecular and morphological evolutionary responses and phenomena such as host-switching and cospeciation.Read moreRead less
Evolution of the unique fauna of the Great Artesian Basin mound springs: the impact of aridification and climate change. The mound springs of the Great Artesian Basin represent one of Australia's most unique environments and are of national biodiversity, cultural and economic significance.

The mound springs of the Great Artesian Basin represent one of Australia's most unique environments and are of national biodiversity, cultural and economic significance. Their conservation is a major issue following listing of the springs as a threatened ecological community. As economic productivity in the GAB intensifies, the mound springs are under increasing threat from escalating groundwater use. The results of this study on the evolution of two crustacean groups will provide significant biological information for management plans, facilitating conservation of mound springs communities, and helping to understand the impacts of water extraction and climate change on this unique habitat.Read moreRead less

As economic productivity in the GAB intensifies, the mound springs are under increasing threat from escalating groundwater use. The results of this study of genetic diversity in the spring communities will provide a means for the management groups to incorporate a significant biological information into their decision making and help facilitate the conservation of mound springs communities in the Lake Eyre regionRead moreRead less
Assessment of the diversity, distribution and uniqueness of subterranean animals from calcrete aquifers in central western Australia. Recently a rich and diverse subterranean invertebrate fauna (stygofauna) was unexpectedly discovered from numerous isolated calcrete aquifers associated with palaeodrainage channels in central Western Australia. Our recent taxonomic and molecular studies have suggested that stygofaunas within each aquifer may be highly endemic. We aim to test this hypothesis by in ....Assessment of the diversity, distribution and uniqueness of subterranean animals from calcrete aquifers in central western Australia. Recently a rich and diverse subterranean invertebrate fauna (stygofauna) was unexpectedly discovered from numerous isolated calcrete aquifers associated with palaeodrainage channels in central Western Australia. Our recent taxonomic and molecular studies have suggested that stygofaunas within each aquifer may be highly endemic. We aim to test this hypothesis by investigating the diversity, distribution and uniqueness of stygofauna from three major calcrete regions. We further aim to document the environmental conditions and variability within the aquifers and to develop rigorous sampling protocols. Such data are essential for the development of appropriate strategies for sustainable management of subterranean water and their ecosystems.Read moreRead less
Genetic evaluation of the diversity of the stygobitic fauna of the Pilbara, Western Australia. This study has two main aims, designed to help manage populations of the subterranean invertebrate fauna in an economically important region of Western Australia: 1) to provide phylogenetic and population genetic information on the structure of populations of amphipods and other groundwater fauna in the Pilbara, Western Australia, and 2) to investigate areas of the ecology of the fauna including respon ....Genetic evaluation of the diversity of the stygobitic fauna of the Pilbara, Western Australia. This study has two main aims, designed to help manage populations of the subterranean invertebrate fauna in an economically important region of Western Australia: 1) to provide phylogenetic and population genetic information on the structure of populations of amphipods and other groundwater fauna in the Pilbara, Western Australia, and 2) to investigate areas of the ecology of the fauna including response to changes in water chemistry. The genetic information will be used to gain an understanding of species diversity, distributions, and movement in order to help set conservation priorities in managing resources, habitats, and fauna. The ecological data will be used to study the effects of dewatering and changes in water chemsitry on morphology and survival.Read moreRead less

State of Art Particle Size Analysers. Particulate materials are encountered in many different forms, sizes and environments, and vastly different areas such as biological, environmental, chemical and materials engineering. Particle size and its distribution are fundamental properties of these materials. Existing particle size measuring equipment in Australia is poor as currently available facilities cannot accurately resolve particle sizes in concentrated dispersions, nor can they visualise the ....State of Art Particle Size Analysers. Particulate materials are encountered in many different forms, sizes and environments, and vastly different areas such as biological, environmental, chemical and materials engineering. Particle size and its distribution are fundamental properties of these materials. Existing particle size measuring equipment in Australia is poor as currently available facilities cannot accurately resolve particle sizes in concentrated dispersions, nor can they visualise the in situ structure and size of fragile assemblies of particles (flocs). This proposal seeks funding for a suite of complementary particle size analysers, for use in an extensive number of research areas, to specifically address these critical current deficits.Read moreRead less
Site factors and genotype-site interaction affecting growth of eucalypt hybrids bred for commercial agro-forestry as a salinity management tool. Preliminary results indicate that with appropriate site-genotype matching, commercial plantation forestry can be pushed well below the current limit (650-700mm/yr). Outcomes from this project will potentially facilitate doubling of Australia's forest plantations, eliminate the annual trade deficit of $2 billion in forest products; ensure the long term e ....Site factors and genotype-site interaction affecting growth of eucalypt hybrids bred for commercial agro-forestry as a salinity management tool. Preliminary results indicate that with appropriate site-genotype matching, commercial plantation forestry can be pushed well below the current limit (650-700mm/yr). Outcomes from this project will potentially facilitate doubling of Australia's forest plantations, eliminate the annual trade deficit of $2 billion in forest products; ensure the long term environmental and productive sustainability of our agricultural production systems; diversify and drought proof farm income through the introduction of perennial tree crops whose yield and harvest is independent of short term seasonal fluctuations; and re-invigorate the economy of rural Australia brought about by investment in new, inland forest and wood processing industries.Read moreRead less
Producing Biodiversity: A History of Science in Australia's Desert Lands. Biodiversity conservation is regarded by most people as desirable, but its historical and cultural aspects are poorly understood. It is not just about scientific understanding of animals and plants, but also a matter of practice and negotiation. People and places are changed through conservation and these changes in turn shape the ways nature is imagined and managed.

Biodiversity conservation is regarded by most people as desirable, but its historical and cultural aspects are poorly understood. It is not just about scientific understanding of animals and plants, but also a matter of practice and negotiation. People and places are changed through conservation and these changes in turn shape the ways nature is imagined and managed. Producing Biodiversity documents historical and contemporary initiatives in biodiversity management on six very different pastoral properties on the margins of the Australian desert. We provide a long-term perspective on national and local conservation imperatives in different eras, and explore how they affect pastoral, Aboriginal and scientific communities.Read moreRead less
