Uncovering the genetic basis for saxitoxin production in Australian marine and freshwater systems: novel molecular tools for management. In Australia, toxic algal blooms have had a devastating impact on marine and freshwater resources. In collaboration with a biotechnology company, this project will use an innovative method to design a molecular genetic tool to monitor, research and potentially mitigate the effects of saxitoxin production on water supplies and aquaculture industries. In working ....Uncovering the genetic basis for saxitoxin production in Australian marine and freshwater systems: novel molecular tools for management. In Australia, toxic algal blooms have had a devastating impact on marine and freshwater resources. In collaboration with a biotechnology company, this project will use an innovative method to design a molecular genetic tool to monitor, research and potentially mitigate the effects of saxitoxin production on water supplies and aquaculture industries. In working with monitoring authorities throughout Australia, we will produce a specific, sensitive and cost-effective technology that will ultimately be applicable worldwide. Read moreRead less
Climate change and ocean acidification: will southern ocean coccolithophorids be winners or losers? Implications for the global carbon pump. This proposal brings skills on morphotaxonomy, microalgal culturing, physiology and biogeochemistry into the flurry of international activity focusing on consequences of ocean acidification. Increasing atmospheric carbon dioxide (CO2) is predicted to reduce calcification in the phytoplankton Emiliania huxleyi, notably in the Southern Ocean. In contrast, hi ....Climate change and ocean acidification: will southern ocean coccolithophorids be winners or losers? Implications for the global carbon pump. This proposal brings skills on morphotaxonomy, microalgal culturing, physiology and biogeochemistry into the flurry of international activity focusing on consequences of ocean acidification. Increasing atmospheric carbon dioxide (CO2) is predicted to reduce calcification in the phytoplankton Emiliania huxleyi, notably in the Southern Ocean. In contrast, higher CO2 may stimulate photosynthesis and enhanced stratification may also select for E. huxleyi. These changes will affect foodwebs and the ability of the ocean to absorb CO2. Predicting the future success of this key organism is vital to understand the consequences of global change in Australian and Southern Ocean waters and to set targets for carbon emissions.Read moreRead less
Mechanisms of acclimation of coralline algae to ocean acidification. This project aims to investigate the biological and ecological mechanisms by which reef-building coralline algae may have survived past ocean acidification and warming events and may acclimate to future changes. Coralline algae play critical roles in coral reef ecology but are sensitive to human-induced ocean acidification. However, the abundant geological record coincident with past acidification events is inconsistent with th ....Mechanisms of acclimation of coralline algae to ocean acidification. This project aims to investigate the biological and ecological mechanisms by which reef-building coralline algae may have survived past ocean acidification and warming events and may acclimate to future changes. Coralline algae play critical roles in coral reef ecology but are sensitive to human-induced ocean acidification. However, the abundant geological record coincident with past acidification events is inconsistent with their sensitivity to high carbon dioxide. Acclimation and adaptation is therefore possible but in ways we do not yet understand. The project expects to provide insights to the ability of key marine organisms to acclimate to rapid environmental change and provide information critical for the conservation of valuable marine systems.Read moreRead less
ARC Centre of Excellence for Plant Success in Nature and Agriculture. The ARC CoE for Plant Success in Nature and Agriculture will discover the adaptive strategies underpinning productivity and resilience in diverse plants and deepen knowledge of the genetic and physiological networks driving key traits. Using novel quantitative and computational approaches, the Centre will link gene networks with traits across biological levels, giving breeders an unparalleled predictive capacity. The Centre wi ....ARC Centre of Excellence for Plant Success in Nature and Agriculture. The ARC CoE for Plant Success in Nature and Agriculture will discover the adaptive strategies underpinning productivity and resilience in diverse plants and deepen knowledge of the genetic and physiological networks driving key traits. Using novel quantitative and computational approaches, the Centre will link gene networks with traits across biological levels, giving breeders an unparalleled predictive capacity. The Centre will accelerate technologies to transfer successful networks into crops and build legal frameworks to secure this knowledge. With a uniquely multidisciplinary team, the Centre will deliver new strategies to address the problems of food security and climate change, establishing Australia as a global leader in these areas.Read moreRead less
