Can endosymbionts alter climate change resilience in insects? This project aims to establish whether endosymbionts alter climate change vulnerability and investigate the potential for endosymbionts to be used as a tool to modify climate change resilience in insects. Heritable endosymbionts – microscopic bacteria living exclusively within host cells – are widespread in insects.

This project aims to establish whether endosymbionts alter climate change vulnerability and investigate the potential for endosymbionts to be used as a tool to modify climate change resilience in insects. Heritable endosymbionts – microscopic bacteria living exclusively within host cells – are widespread in insects. A handful of studies indicate that endosymbionts may influence the thermal tolerance of their host, yet whether they alter the upper thermal limits and climate change risk of insects is unknown. This fellowship will provide a greater understanding of the consequences of climate change on species persistence, as well as opening up avenues to utilise endosymbionts as a tool to manipulate the climate change resilience of insects.

A theory for the vertical structure of tropical atmospheric circulations. The vertical structure of atmospheric circulations is a key determinant of rainfall patterns and climate, but model projections do not agree on how it will change in a warmer world. This project aims to discover the processes that control the vertical structure of tropical atmospheric circulations. It will combine theory development, analysis of observations, and targeted modelling to generate new knowledge of the mechanis ....A theory for the vertical structure of tropical atmospheric circulations. The vertical structure of atmospheric circulations is a key determinant of rainfall patterns and climate, but model projections do not agree on how it will change in a warmer world. This project aims to discover the processes that control the vertical structure of tropical atmospheric circulations. It will combine theory development, analysis of observations, and targeted modelling to generate new knowledge of the mechanisms affecting atmospheric circulations as the climate changes. This will allow for process-based identification of the most reliable climate models, facilitating increased confidence in future projections. More accurate tropical climate projections will benefit decision making for resource management in northern Australia.Read moreRead less

This project aims to develop new strategies to design and tune the performance of multifunctional catalysts for the conversion of carbon dioxide as a sustainable feedstock for the production of valuable commodity chemicals used in the manufacture of consumer products. New insights into reaction mechanisms, and relationships between catalyst structure and performance, are expected through innovative analytical tools. Anticipated outcomes include a toolkit of catalyst design principles, underpinning the development of next-generation catalysts with superior energy efficiency, waste minimisation, and associated socioeconomic benefits, which should contribute significantly to Australian science, industry and the environment.

Social implications of market-based policy instruments for carbon and water. This project aims to analyse socio-cultural benefits and risks in the two significant environmental markets of carbon and water across three sites in Australia and Timor-Leste. Research into market-based policies to manage significant environmental issues is yet to fully consider socio-cultural dimensions. This project intends to document local community producers, distant investor and consumer perspectives, and incorpo ....Social implications of market-based policy instruments for carbon and water. This project aims to analyse socio-cultural benefits and risks in the two significant environmental markets of carbon and water across three sites in Australia and Timor-Leste. Research into market-based policies to manage significant environmental issues is yet to fully consider socio-cultural dimensions. This project intends to document local community producers, distant investor and consumer perspectives, and incorporate these perspectives into methods for improving the operation and impact of these expanding markets. By undertaking the first systematic comparison across resources and sites, the project expects to fill a key gap in environmental scholarship and contribute to international strategies to improve social and environmental outcomes in market-based environmental policy.Read moreRead less
Algal direct-air CO2 capture through interfacial enzyme immobilisation . Capturing CO2 directly from the atmosphere is challenging due to inherently slow mass transfer kinetics. This project aims to overcome this using an enzyme that can rapidly solubilise CO2 from air into water, to produce algae. By engineering the enzyme immobilisation at the air-water interface, this project will activate and protect the enzymes, increasing their lifespan and reducing costs. By understanding mass transfer an ....Algal direct-air CO2 capture through interfacial enzyme immobilisation . Capturing CO2 directly from the atmosphere is challenging due to inherently slow mass transfer kinetics. This project aims to overcome this using an enzyme that can rapidly solubilise CO2 from air into water, to produce algae. By engineering the enzyme immobilisation at the air-water interface, this project will activate and protect the enzymes, increasing their lifespan and reducing costs. By understanding mass transfer and enzyme activity in the interfacial immobilisation media, floating enzyme rafts can be developed for deployment over expansive areas, facilitating large-scale conversion of atmospheric CO2 into algae-derived fuels, feeds and chemicals.Read moreRead less

Contested Geographies of Terrestrial Carbon. National pledges to tackle climate change rely heavily on land to sequester and store carbon. How competing ideas about land use are negotiated and institutionalised in the climate regime is critical to effective, just and legitimate climate responses.

How competing ideas about land use are negotiated and institutionalised in the climate regime is critical to effective, just and legitimate climate responses. This project aims to explain the political economy of the science and policy of land-based climate mitigation, generating new knowledge on who promotes carbon sinks and why. The expected project outcomes include guidelines to advance more just and sustainable land use through improved carbon accounting practices, using an innovative approach that combines stakeholder interviews, discourse analysis, and expert elicitation. These outcomes will notably benefit rural communities and farmers.Read moreRead less

This project aims to improve our understanding of the role of fluids in controlling exchanges between the deep Earth, shallow rocks, and atmosphere. The project expects to investigate some of the key weaknesses in the thermodynamic models that are used to predict the behaviour of sulphur, carbon and metals in fluids at high pressure and temperature by using recent advances in computational and experimental (geo)chemistry. Integrated in large-scale geodynamic models, the more reliable predictions will provide a more realistic assessment of the role of sulphur in controlling metal endowment and atmospheric chemistry through geological times. This should provide a useful guide for mineral exploration and planetary science.Read moreRead less
