Quantifying the impacts of environmental stress on marine microorganisms. Microorganisms underpin marine ecosystem health, yet there is limited understanding of how they will respond to different environmental pressures. This project will resolve this critical knowledge gap by developing a unique molecular platform for deriving quantitative stress thresholds for microbial communities inhabiting key reef habitats (seawater, sediments, invertebrates). Quantifying how reef microorganisms respond to ....Quantifying the impacts of environmental stress on marine microorganisms. Microorganisms underpin marine ecosystem health, yet there is limited understanding of how they will respond to different environmental pressures. This project will resolve this critical knowledge gap by developing a unique molecular platform for deriving quantitative stress thresholds for microbial communities inhabiting key reef habitats (seawater, sediments, invertebrates). Quantifying how reef microorganisms respond to a broad suite of environmental perturbations (temperature, nutrients, contaminants), will generate stress-response data that can be incorporated alongside eukaryotic data in environmental assessments, greatly improving the ecological relevance and reliability of risk and vulnerability assessments.Read moreRead less
Coral-associated viruses: pathogens, mutualists and agents of evolution? Corals host numerous organisms, of which viruses are the least studied. The aim of this project is to characterise the viruses associated with corals and to obtain a detailed understanding of the critical roles that viruses play in coral health, coral bleaching and adaptation of corals to climate change.
Revealing the structure, evolution and sensitivity of symbioses in basal metazoa. This project will explore the complex interactions between each component of the sponge holobiont (virus, bacteria, sponge) during thermal stress. This will also provide the first molecular assessment of sponge viruses and provide insights into how sponges may adapt to a changing climate.
A Changing Climate on the Great Barrier Reef: Present and Future Implications. The Great Barrier Reef is fundamental to the economy of Australia. This national and international icon needs to be preserved in the face of a changing world to ensure on-going sustainability of our marine resources. Ocean acidification, warming water temperatures, increased freshwater disrupt the sensitive symbiotic association of corals the major structure building organisms of reefs. Understanding how these enviro ....A Changing Climate on the Great Barrier Reef: Present and Future Implications. The Great Barrier Reef is fundamental to the economy of Australia. This national and international icon needs to be preserved in the face of a changing world to ensure on-going sustainability of our marine resources. Ocean acidification, warming water temperatures, increased freshwater disrupt the sensitive symbiotic association of corals the major structure building organisms of reefs. Understanding how these environmental stressors result in the decrease in coral health is fundamental to prevent loss of our coral reefs and an important step towards preserving them for future generations.Read moreRead less
