This project aims to identify the origins and movements of Australian archaeological ochre through the development of a novel tool combining genomic and chemical analysis. The geographic distribution of Australian ochre is closely linked to Aboriginal creation stories, while its physical distribution by people is evidence of cultural cooperation. Using this new archaeomicrobiological technique, the project aims to answer significant questions about past human behaviour, in terms of trade, cultural interactions, territoriality and colonisation. The method also has the potential to benefit traditional owners by contributing to repatriation projects. The collaborative detailed recording, sampling and analysis of ochre sources on traditional lands will also assist Aboriginal communities to manage this important aspect of their cultural heritage.Read moreRead less
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
