The role of biological and chemical interactions in the rhizosphere in sustainable intercropping systems. Intercropping can result in large yield increases compared to mono-cropped systems. It is used extensively in China and could be an option for sustainable land-use in Australia. Belowground interactions between intercropped crop species may be important for the yield increase, but they are poorly understood, especially with regard to nutrient availability and soil biology. We will combine th ....The role of biological and chemical interactions in the rhizosphere in sustainable intercropping systems. Intercropping can result in large yield increases compared to mono-cropped systems. It is used extensively in China and could be an option for sustainable land-use in Australia. Belowground interactions between intercropped crop species may be important for the yield increase, but they are poorly understood, especially with regard to nutrient availability and soil biology. We will combine the field experience in intercropping systems of the Chinese scientists with the expertise of the Australian scientists in plant nutrition and rhizosphere ecology to characterise chemical and biological interactions in the rhizosphere governing nutrient availability and the competitive ability of intercropped species.Read moreRead less
Setting Geographic Priorities for Integrated Landscape Restoration in a Fragmented Agricultural Region. This research project aims to develop the theory and application of integrated landscape restoration in a fragmented agricultural region - the Mt. Lofty Ranges of South Australia. Spatially explicit priorities will be set for the type and location of habitat to be restored for the benefit of the natural biodiversity within a physical environmental, economic and social context. Heuristic and op ....Setting Geographic Priorities for Integrated Landscape Restoration in a Fragmented Agricultural Region. This research project aims to develop the theory and application of integrated landscape restoration in a fragmented agricultural region - the Mt. Lofty Ranges of South Australia. Spatially explicit priorities will be set for the type and location of habitat to be restored for the benefit of the natural biodiversity within a physical environmental, economic and social context. Heuristic and optimisation models will be created within a Geographic Information System (GIS) and assessed for their ability to set such priorities in integrated landscape restoration. The techniques will help sustain ecological, physical and human systems in many other over-cleared regions.Read 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
Phytocapping for sustainable waste containment systems and reduction of greenhouse gas emissions and odour from waste disposal sites. Landfills remain the main method of waste disposal in Australia and are a major source of groundwater contamination and greenhouse and odour emissions.

Landfills remain the main method of waste disposal in Australia and are a major source of groundwater contamination and greenhouse and odour emissions. This national research program will establish, under a wide range of Australian conditions, whether landfill phytocaps can meet regulatory performance criteria for water infiltration into and gas emissions from closed landfills more effectively, efficiently and sustainably than conventional capping systems. The project will produce (a) a scientific basis for site owners and regulators to agree on the performance and cost of conventional and phyto cover technologies, (b) a manual for the design and permitting of alternative covers and (c)improved scientific prediction of cover performance.Read moreRead less

Tracing Past and Present Pollution Sources in the River Torrens, South Australia. The Torrens River is the principal water supply to 500,000 South Australians. Since early in European settlement it has suffered the impacts of eutrophication and high rates of sedimentation. The Catchment Management Board is seeking to prioritise rehabilitation resources to maximise water quality improvements. This will be informed by the revelation of the principal sources of sediment and nutrients over time.
Assessing the Groundwater Dependence of Nearshore Coastal Ecosystems in the South East of South Australia. Groundwater in the SE region of SA is a valuable resource.

Groundwater in the SE region of SA is a valuable resource. The South East Catchment Water Management Board is responsible for planning sustainable management of these resources. The Board seeks to discover whether any marine ecosystems are dependent upon these groundwater resources, to inform their water-allocation planning decisions. This research combines field-based marine ecology with groundwater hydrology to assess the influence of groundwater outflow upon small estuaries, sandy beaches and lagoonal seagrass meadows that exist along the coastline from Kingston SE to the Victorian border. Our multidisciplinary approach will set a benchmark nationally and internationally for such applied research.Read moreRead less
Linking fish recruitment and habitat use to ecosystem processes. Estuaries are transition zones between fresh and marine waters and form key nursery areas for fisheries. Understanding what makes an estuary a nursery area, and how dependent fish are on estuaries, is difficult because we lack vital information on fish recruitment and migrations.

Estuaries are transition zones between fresh and marine waters and form key nursery areas for fisheries. Understanding what makes an estuary a nursery area, and how dependent fish are on estuaries, is difficult because we lack vital information on fish recruitment and migrations. We will utilise chemical and genetic techniques to determine patterns of recruitment and migration of fish and link these patterns to biological characteristics of fish and physical variables of surrounding landscapes. Outcomes will provide managers with key landscape attributes than require conservation. Such information is vital for continued sustainability of fish and estuarine resources and will benefit rural coastal communities.Read moreRead less

The project aims at intelligent adaptive agent models for lakes and rivers in order to improve understanding and proactive management of these highly complex ecosystems. Little is known about species succession in freshwater ecosystems in response to local and global environmental changes. Evolutionary algorithms embodied in differential equations, neural networks and rules allow adaptive agents to simulate emergent structures and behaviours of algae and zooplankton communities interacting by competition and predation. The agents are trained and tested by ecological time-series of twelve lakes and rivers, and validated for the Mediterranean Myponga Reservoir, South Australia, and the temperate Burrinjuck Reservoir, NSW.Read moreRead less
