Regime change: when and how do ecological subordinates turn dominant? This project aims to bridge the gap between physiology and ecology in kelp forest species by developing mechanistic models to predict change and, in an unprecedented step, test them in long-term experiments at naturally acidified sites to understand the consequences of ocean acidification (OA) and warming for kelp forests. Ecosystem change is a frequent outcome of decadal modifications of the physical and chemical environment. ....Regime change: when and how do ecological subordinates turn dominant? This project aims to bridge the gap between physiology and ecology in kelp forest species by developing mechanistic models to predict change and, in an unprecedented step, test them in long-term experiments at naturally acidified sites to understand the consequences of ocean acidification (OA) and warming for kelp forests. Ecosystem change is a frequent outcome of decadal modifications of the physical and chemical environment. Whilst these changes often involve degradation from productive states, we have a poor understanding of the mechanisms which drive change. Key stressors in marine systems, OA and warming are predicted to drive loss of kelp forests but we still don't understand the reality of these predictions.Read moreRead less
Silicon: a novel solution to reduce water use and pest damage in wheat. The project aims to improve Australian wheat production by increasing drought resilience and reducing reliance on pesticides. This is achieved by incorporating amorphous silicon (Si), an abundant national resource. Si uptake by wheat has been proven to alleviate stress from drought and pests, but mechanisms and agronomic feasibility remain to be fully assessed. The project will deliver a mechanistic understanding of how Si a ....Silicon: a novel solution to reduce water use and pest damage in wheat. The project aims to improve Australian wheat production by increasing drought resilience and reducing reliance on pesticides. This is achieved by incorporating amorphous silicon (Si), an abundant national resource. Si uptake by wheat has been proven to alleviate stress from drought and pests, but mechanisms and agronomic feasibility remain to be fully assessed. The project will deliver a mechanistic understanding of how Si alleviates stress in wheat, from gene to farm scale, providing cost-benefit analysis and a best–practice toolbox for implementation by farmers. Outcomes are anticipated to provide a cheaper and more environmentally sustainable solution to issues of water scarcity and yield losses to pests in Australia’s leading crop.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
