From individuals to mass organisation: aggregation, synchronisation and collective movement in locusts. By combining field biology, robotics and mathematics, this project will determine how animals flock or swarm and, in particular, how locust nymphs control their collective movement over their lifetime. The mathematical models derived during the project will be directly applied to controlling outbreaks of locusts in Australia, South and North Africa.
Testing our knowledge on the dawn of animal life: evidence from the fossil record against modern ecological and morphological analogues. The Cambrian 'Explosion', half a billion years ago, is regarded as one of the most important events in the history of the Earth, when most major animal groups first appear in the rock record, and for which South Australia has recently become a significant source of spectacular fossils. However, important questions remain regarding their Ediacaran roots, the spe ....Testing our knowledge on the dawn of animal life: evidence from the fossil record against modern ecological and morphological analogues. The Cambrian 'Explosion', half a billion years ago, is regarded as one of the most important events in the history of the Earth, when most major animal groups first appear in the rock record, and for which South Australia has recently become a significant source of spectacular fossils. However, important questions remain regarding their Ediacaran roots, the speed of evolution at the time, and the environments in which the radiation took place. Studying the fossil evidence in the light of present-day ecological frameworks, and in comparison with modern behavioural and morphological analogues, as well as living relatives, can help us better assess our understanding of this first radiation of animals.Read moreRead less
Establishing a global framework to trace the provenance of seafood. The global importance and demand for seafood is higher than ever; yet, sustainable seafood production is threatened by seafood fraud. This research will develop a new technology that will trace the geographic origins of seafood from catch to table and empower authorities to combat fraud. In doing so, this research will use natural chemical variation in biominerals to build maps of ocean chemistry and create universal markers of ....Establishing a global framework to trace the provenance of seafood. The global importance and demand for seafood is higher than ever; yet, sustainable seafood production is threatened by seafood fraud. This research will develop a new technology that will trace the geographic origins of seafood from catch to table and empower authorities to combat fraud. In doing so, this research will use natural chemical variation in biominerals to build maps of ocean chemistry and create universal markers of seafood provenance. These markers will be intrinsically tamper-proof: enabling the chemical geolocation of seafood across international trade routes. The outcome of this research will address a global environmental challenge and, in doing so, deliver benefits to the Australian economy, consumer and environment. Read moreRead less
Safeguarding coral reef fisheries for future food security. This Fellowship aims to address the vulnerability of coral reef fisheries in Australia and the Indo-Pacific by identifying fishery targets that benefit human nutrition and will persist despite declining coral habitats and rising water temperature. This project will advance knowledge on coral and fish responses to increasingly frequent marine heatwaves, using novel methodologies rooted in ecological modelling, experimental marine biology ....Safeguarding coral reef fisheries for future food security. This Fellowship aims to address the vulnerability of coral reef fisheries in Australia and the Indo-Pacific by identifying fishery targets that benefit human nutrition and will persist despite declining coral habitats and rising water temperature. This project will advance knowledge on coral and fish responses to increasingly frequent marine heatwaves, using novel methodologies rooted in ecological modelling, experimental marine biology and climate forecasting. Expected outcomes include (i) a comprehensive toolbox for improved management of coral reefs and associated fisheries in Australia and beyond, and (ii) an integrated socio-ecological model for predicting coral reef fishery responses under environmental change.Read moreRead less
Kelp forest ecosystems near and far: Putting a new theory explaining dynamic ecological systems to the test. Few, if any, ecological models account for the biological diversity and observed vulnerability of ecosystems, from the molecular to the oceanic scale. This project aims to investigate kelp forests in ways that integrate previously disparate approaches to the study of ecosystems in order to prove the value of a novel framework for understanding how broad-scale and local phenomena interrela ....Kelp forest ecosystems near and far: Putting a new theory explaining dynamic ecological systems to the test. Few, if any, ecological models account for the biological diversity and observed vulnerability of ecosystems, from the molecular to the oceanic scale. This project aims to investigate kelp forests in ways that integrate previously disparate approaches to the study of ecosystems in order to prove the value of a novel framework for understanding how broad-scale and local phenomena interrelate to maintain the diversity and function of ecosystems or to provoke their decline, transition or collapse. This new conceptualisation of ecosystem processes will assist in forecasting the consequences of their management and the effects of external stimuli on normally robust systems. Read moreRead less
Ocean acidification and rising sea temperature effect on fish. Predictions of climate change effects on marine biodiversity often do not include species interactions. This project will study the effects of climate change stressors on the behaviour and competitive abilities of fishes and build models that predict how these affect their survival and persistence in marine ecosystems under future climate scenarios.
Using ancient fish ear bones to overcome the shifting baseline syndrome in freshwater fish populations. Chemical tracers in fish ear bones from 5,500 years ago through to modern times will provide information on changes in fish ecology over centuries and identify why freshwater fish populations have declined. Outcomes will provide knowledge of how fish populations would react to altered fishing pressure and restoration of environments.
