Mechanisms of proxy uptake in biominerals. This project plans to combine nano-analytical and aquaculture methods to develop new models that improve the reliability of paleoclimate reconstructions. The compositions of shells and skeletal materials of marine invertebrates are essential archives for quantifying temperatures and environmental conditions before modern climate records began. However, their reliability relies on understanding their formation. Emerging knowledge from material sciences i ....Mechanisms of proxy uptake in biominerals. This project plans to combine nano-analytical and aquaculture methods to develop new models that improve the reliability of paleoclimate reconstructions. The compositions of shells and skeletal materials of marine invertebrates are essential archives for quantifying temperatures and environmental conditions before modern climate records began. However, their reliability relies on understanding their formation. Emerging knowledge from material sciences indicates that these biocarbonates form via transient precursors rather than direct precipitation from seawater, profoundly affecting their interpretation. This project plans to transfer this new understanding to the earth sciences using nanoscale analytical methods including in vitro geochemical partitioning experiments. This would enable realistic models for geochemical proxy behaviour to be developed, significantly improving paleoclimate interpretations and assessments of ocean acidification effects on marine calcifiers.Read moreRead less
Millennial climate change in southern Australia during the Last Glacial. Abrupt warming and cooling events were a persistent feature of Earth's most recent climate cycle. Surprisingly, little is known of how these events affected the climate of Australia. This project will produce precisely dated reconstructions of rainfall and temperature trends in southern Australia during these events. These new terrestrial and ocean data will be compared with model simulations to determine how rapidly abrupt ....Millennial climate change in southern Australia during the Last Glacial. Abrupt warming and cooling events were a persistent feature of Earth's most recent climate cycle. Surprisingly, little is known of how these events affected the climate of Australia. This project will produce precisely dated reconstructions of rainfall and temperature trends in southern Australia during these events. These new terrestrial and ocean data will be compared with model simulations to determine how rapidly abrupt climate perturbations in the Northern Hemisphere reached our region, and the processes by which this occurred. The results will advance theory on how abrupt climate change propagates globally and provide a long-awaited climatic context for capstone events in Australia's natural history.Read moreRead less

Poleward bound: mechanisms and consequences of climate-driven species redistribution in marine ecosystems. Global redistribution of Earth's species is widely recognised as a fingerprint of climate change. However, the physiological and ecological processes that underpin such shifts in the distribution of marine species are poorly understood. Even less is known about why species respond at different rates, and how such widespread changes will impact the structure and function of Australia's marin ....Poleward bound: mechanisms and consequences of climate-driven species redistribution in marine ecosystems. Global redistribution of Earth's species is widely recognised as a fingerprint of climate change. However, the physiological and ecological processes that underpin such shifts in the distribution of marine species are poorly understood. Even less is known about why species respond at different rates, and how such widespread changes will impact the structure and function of Australia's marine ecosystems. This research will address critical knowledge gaps of why and how species respond in vastly different ways to environmental change. Research outcomes will improve the capacity to predict responses of marine species and ecosystems to climate change and provide advice relevant to strategic management of valuable natural resources.Read moreRead less
A dynamical systems theory approach to machine learning. Forecasting the future state of a high-dimensional complex multi-scale system is a challenge we face in areas ranging from climate science to epidemiology. Even when basic physical mechanisms have been identified, the actual evolution equations are often unknown. This project will develop a computationally cheap machine learning framework for forecasting. The proposed mathematical framework provides a forecast together with a quantificati ....A dynamical systems theory approach to machine learning. Forecasting the future state of a high-dimensional complex multi-scale system is a challenge we face in areas ranging from climate science to epidemiology. Even when basic physical mechanisms have been identified, the actual evolution equations are often unknown. This project will develop a computationally cheap machine learning framework for forecasting. The proposed mathematical framework provides a forecast together with a quantification of its uncertainty. We will develop sophisticated mathematical theory underpinning the novel methodology, as well as applying it to the perennial problem of subgrid-scale parametrisation of tropical convection, a missing key element in current climate models.Read moreRead less
Maternal contributions to offspring development in a changing climate. This project aims to investigate how maternal contributions to offspring developmental environments affect metabolism, learning, growth, and survival of offspring. This project expects to provide mechanistic and evolutionary insights into how changes in metabolic function, brought about by changes in the developmental environment, contribute to variation in learning and life-history. Expected outcomes include an in-depth unde ....Maternal contributions to offspring development in a changing climate. This project aims to investigate how maternal contributions to offspring developmental environments affect metabolism, learning, growth, and survival of offspring. This project expects to provide mechanistic and evolutionary insights into how changes in metabolic function, brought about by changes in the developmental environment, contribute to variation in learning and life-history. Expected outcomes include an in-depth understanding of how changes in maternal investment and hormones impact offspring developing in different thermal environments and how such changes are mediated by compromised physiological function – providing significant benefits in understanding population persistence in Australia's rapidly changing climate.Read moreRead less

This project will combine genomics, artificial intelligence and experimental ecology to develop guidelines and technologies that maximise the growth and resilience of key seaweed species for aquaculture. Industrial seaweed production is growing rapidly and is expected to supply 1000s of jobs to regional Australia and 10% to the nation’s emissions reduction target by 2040. Expected outcomes of this project include a genomics-based regulatory framework and hatchery tools that support rapid industry growth and minimise biosecurity and climate change risks. This will benefit government, aquaculture, and ecosystem management by improving design, assessment and implementation options for sustainable and productive use of Australian seaweeds.Read moreRead less
Evolving landscapes of our early South African ancestors. This project aims to reconstruct the early evolution of our genus, from 2.6 to 1.8 million years ago. This was a time of faunal and environmental change, the extinction of apelike human ancestors (Australopithecus), the speciation of a specialised human genus, Paranthropus, and the origin of our own genus, Homo. This project will study South African cave sites, the surrounding karst, and the oldest known Homo ergaster fossil to model chan ....Evolving landscapes of our early South African ancestors. This project aims to reconstruct the early evolution of our genus, from 2.6 to 1.8 million years ago. This was a time of faunal and environmental change, the extinction of apelike human ancestors (Australopithecus), the speciation of a specialised human genus, Paranthropus, and the origin of our own genus, Homo. This project will study South African cave sites, the surrounding karst, and the oldest known Homo ergaster fossil to model changing dietary patterns and landscape use by hominins. This project expects to reconstruct the early evolution of our genus and to address how species reacted to changing environmental conditions and increasing aridity.Read moreRead less
Urbanism after Angkor (14th-18th century). This project aims to understand changes after the breakdown of low-density urbanism in Cambodia. Recognising the emergence of urban forms after the demise of Angkor challenges the global “Collapse of Civilisation” trope, and redefines the Middle Period of Cambodian history (15th-19th century). This project proposes that continuity, renewal, variety and adaptation are as apparent in Cambodia’s middle period as loss and failure.

Recognising the emergence of urban forms after the demise of Angkor challenges the global “Collapse of Civilisation” trope, and redefines the Middle Period of Cambodian history (15th-19th century). This project proposes that continuity, renewal, variety and adaptation are as apparent in Cambodia’s middle period as loss and failure. Applying landscape archaeology to this ‘dark age’ of Southeast Asian history embeds the demise of low-density urbanism and the development of towns in an environmental context. Identifying adaptive pathways after ‘collapse’ could have implications for urbanism in the tropics.Read moreRead less
Determining fossilisation processes of a rare iron-rich Lagerstätte. Most fossil sites only preserve resistant elements such as bones and teeth, leading to questions about how soft animals and structures have evolved over time. The recent discovery of a fossil deposit in New South Wales appears to demonstrate a new set of conditions for the preservation of soft tissues. This project aims to constrain the age of and assess the fossilisation processes that produced this unique fossil site. We will ....Determining fossilisation processes of a rare iron-rich Lagerstätte. Most fossil sites only preserve resistant elements such as bones and teeth, leading to questions about how soft animals and structures have evolved over time. The recent discovery of a fossil deposit in New South Wales appears to demonstrate a new set of conditions for the preservation of soft tissues. This project aims to constrain the age of and assess the fossilisation processes that produced this unique fossil site. We will use an integrative approach to reconstruct the formation of this Lagerstätte. The work will provide significant advances in our understanding of the process of fossilisation and guide the discovery of other exceptionally-well preserved fossil deposits, critical in reconstructing the biological history of Australia.Read moreRead less
