Understanding algal bloom microbiome function to improve seafood safety. Current phytoplankton ecological theory is derived primarily from lab cultures, but in nature phytoplankton have unique microbiomes that support their growth and ongoing ocean primary production. This project aims to establish the structure and function of these natural microbiomes, and how they contribute to seafood poisoning caused by bacteria and algal biotoxins. Using advanced flow cytometry with single-cell microbial ....Understanding algal bloom microbiome function to improve seafood safety. Current phytoplankton ecological theory is derived primarily from lab cultures, but in nature phytoplankton have unique microbiomes that support their growth and ongoing ocean primary production. This project aims to establish the structure and function of these natural microbiomes, and how they contribute to seafood poisoning caused by bacteria and algal biotoxins. Using advanced flow cytometry with single-cell microbial profiling, we will sample nano-scale plankton microbiomes and synthetic microbiome phylogenomics to the link between microbiomes and seafood poisoning outbreaks. The outcomes will underpin enhanced predictive modelling of seafood risk to ensure the safety and export security of Australia's $2 billion seafood industry.Read moreRead less
Do marine heat waves cause pathogen outbreaks in Australian coastal waters? This project aims to identify links between increasingly frequent Marine Heat Wave (MHW) events and outbreaks of microbes that cause disease in marine animals, reduced aquaculture yields and human health hazards. Pathogenic bacteria from the Vibrio genus exhibit a preference for elevated seawater temperature and this project will test the hypothesis that episodic MHWs will trigger blooms of dangerous species. Using innov ....Do marine heat waves cause pathogen outbreaks in Australian coastal waters? This project aims to identify links between increasingly frequent Marine Heat Wave (MHW) events and outbreaks of microbes that cause disease in marine animals, reduced aquaculture yields and human health hazards. Pathogenic bacteria from the Vibrio genus exhibit a preference for elevated seawater temperature and this project will test the hypothesis that episodic MHWs will trigger blooms of dangerous species. Using innovative ecogenomic tools, this project will track the impact of MHWs on the dynamics of pathogenic Vibrio within coastal habitats, oyster farming facilities and coral reefs. The benefit of this project will be essential new knowledge on an emerging threat to Australia’s valuable marine estate, food security and public health.Read moreRead less
Coastal tropicalisation – adapting to novel ecosystems and trajectories. This project aims to quantify the impacts of a changing climate on key ecosystem functions of temperate reefs.

This project aims to quantify the impacts of a changing climate on key ecosystem functions of temperate reefs. As global temperate reefs respond to ocean warming, iconic and economically important kelp forests and associated fishes and invertebrates are being lost. Novel communities and never-before seen configurations of species are emerging in these systems. This project aims to characterise the new dynamics of these novel systems, and provide an understanding of how to maintain key ecosystem functions - primary productivity, fish production - that underpin the benefits that humans derive from our coastlines.Read moreRead less
Do binding proteins allow cyanobacteria to scavenge diverse nutrients? Marine cyanobacteria are abundant primary producers that underlie the entire marine food web. They encode a diverse range of predicted nutrient uptake systems that are highly conserved, suggesting these transporters play critical roles in their success in diverse marine ecosystems. However, there is very limited data regarding their function, specificity and ecological importance. Using our pioneering combinatorial approach, ....Do binding proteins allow cyanobacteria to scavenge diverse nutrients? Marine cyanobacteria are abundant primary producers that underlie the entire marine food web. They encode a diverse range of predicted nutrient uptake systems that are highly conserved, suggesting these transporters play critical roles in their success in diverse marine ecosystems. However, there is very limited data regarding their function, specificity and ecological importance. Using our pioneering combinatorial approach, we will undertake systematic functional characterisation of these nutrient uptake systems and determine their physiological and ecological importance. Our integrative science will provide a molecules-to-ecosystems understanding of cyanobacterial nutrient acquisition.Read moreRead less

This project aims to investigate how bacteria can improve the growth, health and environmental adaptation of marine seaweeds (macroalgae). By using new knowledge of microbial functions and innovative approaches in experimental ecology the project will develop bacterial consortia that benefit seaweeds. It is anticipated that these bacteria will constitute novel marine probiotics that can be used to enhance and protect the performance of macroalgae in their natural environment or in aquaculture systems. Such outcomes may contribute to safeguarding marine ecosystems against anthropogenic stressors (such as pollutants) and provide opportunities for the development of a blue economy.Read moreRead less
Defining the Microbial-scale Processes Governing Ocean Health . This project aims to resolve the foundations of healthy ocean function by employing innovative approaches to uncover the links between marine chemistry and microbiology. While the importance of microbes in governing ocean health is unquestionable, they are often studied over inappropriately large-scales, leading to inaccurate interpretation of the oceanic processes that ultimately influence fishery production and climate control.

This project aims to resolve the foundations of healthy ocean function by employing innovative approaches to uncover the links between marine chemistry and microbiology. While the importance of microbes in governing ocean health is unquestionable, they are often studied over inappropriately large-scales, leading to inaccurate interpretation of the oceanic processes that ultimately influence fishery production and climate control. We will develop new oceanographic tools and analytical techniques to provide a unique "microbes-eye-view" of the sea. The project's outcomes are anticipated to deliver transformative new knowledge on the controls of ocean productivity and sustainability, helping to safeguard Australia’s valuable marine estate.Read moreRead less

Little is known about the microbiota inhabiting coral skeletons, but several sources of evidence point to their importance in the coral holobiont. Particularly during coral bleaching, drastic changes happen in the skeletal microbiome, with potential beneficial as well as detrimental effects on the holobiont. This project will characterise the functions of skeletal microbiota, how microbial communities are structured along physico-chemical gradients, and how microbial gene expression changes through coral bleaching. This will lead to better insights into the roles of skeletal microbiota in the holobiont, the processes occurring in the skeleton during bleaching, and the role that skeletal microbiota may play in the fate of bleached corals.Read moreRead less
