Microbe-produced repellents and their roles in marine pathogen behaviours. Economic losses caused by disease outbreaks in marine fisheries and aquaculture exceed US$6 billion per year globally. Decades of research in human and plant pathogens have revealed that the ability of pathogens to infect their host is governed by behaviours; however our understanding of the chemical cues affecting the behaviour of marine pathogens is very poor.

Economic losses caused by disease outbreaks in marine fisheries and aquaculture exceed US$6 billion per year globally. Decades of research in human and plant pathogens have revealed that the ability of pathogens to infect their host is governed by behaviours; however our understanding of the chemical cues affecting the behaviour of marine pathogens is very poor. This research program aims to combine new approaches in microfluidics and chemical imaging to identify the cues that govern the behaviour of marine pathogens. Expected outcomes include an improved capacity to predict, monitor and manage marine diseases, as well as novel strategies to prevent disease outbreaks, helping to protect Australia’s valuable marine estate.Read moreRead less

Summary
The role of marine microbes in the global carbon cycle. This project aims to unravel microbiological processes in the ocean to help quantify the ecosystem services carried out by microbes that support our economy and environment. By recycling vital nutrients, microbes form the basis of the marine food web. In Australia, their contributions support fisheries worth $4.2 billion. Their role in carbon cycling also controls our climate. Yet, their direct productivity remains unquantified. Technical l ....The role of marine microbes in the global carbon cycle. This project aims to unravel microbiological processes in the ocean to help quantify the ecosystem services carried out by microbes that support our economy and environment. By recycling vital nutrients, microbes form the basis of the marine food web. In Australia, their contributions support fisheries worth $4.2 billion. Their role in carbon cycling also controls our climate. Yet, their direct productivity remains unquantified. Technical limitations have restricted our ability to identify the key microbes most responsible for ocean carbon cycling, and to measure their impact. This project plans to combine new approaches in microfluidics, chemistry and oceanography to quantify carbon uptake by individual microbes and provide new understanding of microbe-mediated chemical cycling processes.Read moreRead less
Social networking in a changing ocean: Microbial-scale ecological interactions control ocean-scale chemistry. The function of the ocean is governed by microscopic organisms, including bacteria and phytoplankton. Oceanographers typically consider the ecology of these microbes across large ocean-scales, but their activities and interactions are defined at the scale of individual cells. This research will redefine our knowledge of important marine microbial processes by coupling novel physiologica ....Social networking in a changing ocean: Microbial-scale ecological interactions control ocean-scale chemistry. The function of the ocean is governed by microscopic organisms, including bacteria and phytoplankton. Oceanographers typically consider the ecology of these microbes across large ocean-scales, but their activities and interactions are defined at the scale of individual cells. This research will redefine our knowledge of important marine microbial processes by coupling novel physiological and molecular tools to resolve the microscale ecological links between bacteria and phytoplankton, and will identify how the chemical interactions between these groups change under shifting environmental conditions. This has significance for transforming our understanding of the factors that control the health and function of our important ocean ecosystems.Read moreRead less
