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
Microscale insights into ocean-scale processes: microbial behaviour as a driver of ocean biogeochemistry. Microscopic plankton regulate the ocean's chemical cycles, which ultimately support life on earth. However, the ecological interactions driving these processes are poorly understood. This project will use novel approaches to decipher the behaviours of marine microbes, providing a more complete perception of how ocean ecosystems operate and influence climate.
Carbon costs of plant nutrient and water uptake. This project aims to investigate how much carbon plants need to invest belowground in return for water and nutrients. By using economic principles of supply and demand the project will quantify carbon expenditure for water and nutrients in grasslands and crops under different climate and land management scenarios. This project will use triple and quadruple isotope labelling techniques and explore the dependency of carbon investment on plant-microb ....Carbon costs of plant nutrient and water uptake. This project aims to investigate how much carbon plants need to invest belowground in return for water and nutrients. By using economic principles of supply and demand the project will quantify carbon expenditure for water and nutrients in grasslands and crops under different climate and land management scenarios. This project will use triple and quadruple isotope labelling techniques and explore the dependency of carbon investment on plant-microbial interactions and availability of belowground resources. Expected outcomes include new knowledge to build a universal framework about plant carbon-water-nutrient economics. This will benefit global carbon cycling models and efforts to increase nutrient and water use efficiencies in agricultural crops.Read moreRead less
Keystone microbes and planktonic guilds in Australia's oceans. This project aims to unveil the ocean’s hidden sentinels, “keystone microbes” that underpin precious ecosystem services, and which can be used to monitor and model changes in ocean function. Marine microbes account for 90 per cent of oceanic biomass and every litre of seawater contains ~20,000 different species, but it is not known which species control ocean health and productivity. This project intends to provide definitive evidenc ....Keystone microbes and planktonic guilds in Australia's oceans. This project aims to unveil the ocean’s hidden sentinels, “keystone microbes” that underpin precious ecosystem services, and which can be used to monitor and model changes in ocean function. Marine microbes account for 90 per cent of oceanic biomass and every litre of seawater contains ~20,000 different species, but it is not known which species control ocean health and productivity. This project intends to provide definitive evidence of these keystones’ cellular level biogeochemical and metabolic capacity. Ultimately, this knowledge is expected to predict the resilience of ocean ecosystems and their response to change. The capacity to predict their dynamics will help provide investment clarity and increase healthy outcomes from activities involving human-ocean interactions such as recreation, food production and tourism.Read moreRead less
Alleviating herbicide damage to crops by using fulvate and manganese. Glyphosate is a widely used herbicide, but its drift can cause growth depression in sensitive plants such as wheat by reducing uptake of metallic micronutrients, particularly manganese. In pot and field trials, this project aims to assess the alleviating potential of fulvate and manganese on growth and micronutrient uptake by wheat exposed to glyphosate drift. The influence of land management on the effect of these treatments ....Alleviating herbicide damage to crops by using fulvate and manganese. Glyphosate is a widely used herbicide, but its drift can cause growth depression in sensitive plants such as wheat by reducing uptake of metallic micronutrients, particularly manganese. In pot and field trials, this project aims to assess the alleviating potential of fulvate and manganese on growth and micronutrient uptake by wheat exposed to glyphosate drift. The influence of land management on the effect of these treatments will also be assessed. The underlying mechanisms will be characterised, eg. by determining metal speciation in soil and assessing soil microbial community composition. The outcome of this project will contribute to sustainable agriculture by giving land managers options to reduce glyphosate damage in sensitive crops.Read moreRead less
Microbial Oceanography: Community Heterogeneity Fuelled by Environmental Variability. The ocean is a crucial resource to Australia. This work will open a new area of research within Australian habitats, which will improve our understanding of how the base of the ocean food web functions, and build a new perspective from which to look at the microscopic plankton that influence fisheries yield and species invasions.

The ocean is a crucial resource to Australia. This work will open a new area of research within Australian habitats, which will improve our understanding of how the base of the ocean food web functions, and build a new perspective from which to look at the microscopic plankton that influence fisheries yield and species invasions. Appreciating how microbial communities respond to environmental perturbations will provide an improved vantage-point to predict future changes to the Australian marine environment. Leading international scientists will provide conceptual and technical expertise in an Australian based project, applying novel analytical tools not currently employed within oceanographic surveys within Australian waters.Read moreRead less
