Summary
A transportable containerised laboratory for rapid cell sorting and high-resolution bioimaging of living aquatic microbes in field locations. This project will deliver a transportable, unique laboratory for the rapid isolation and high-resolution analysis of living microbes immediately after sampling from the sea or waterways.

Can eco-evolutionary theories explain outcomes of microbiome coalescence . Environmental microbial communities are among the most abundant and diverse natural communities, responsible for many ecologically and economically important ecosystem functions, including primary productivity and climate regulation.

Environmental microbial communities are among the most abundant and diverse natural communities, responsible for many ecologically and economically important ecosystem functions, including primary productivity and climate regulation. This project aims to identify the biotic and abiotic factors that regulate community and functional outcomes of microbiome coalescence (the mixing of two different communities) caused by natural and anthropogenic activities. The outcomes will provide a unifying ecological framework to predict variation in microbiomes across different scales, ecosystem types and disturbances, and will generate critical knowledge for the development of effective microbiome products, a rapidly growing industryRead moreRead less

In addition, this project has the potential for contributing to improvements in water quality, Australia's growing salinity problem, and in the development of new pharmaceuticals.Read moreRead less
Can cyanobacteria use organic nutrients to thrive in future oceans? Marine cyanobacteria are central to regulating the global climate and underpin entire marine food webs. Though they possess genes necessary to uptake diverse organic nutrients, we know very little about whether and how organic nutrients shape the physiology and ecology of cyanobacteria. Using our innovative high-throughput approach, this project aims to systematically characterise organic nutrient uptake in picocyanobacteria. O ....Can cyanobacteria use organic nutrients to thrive in future oceans? Marine cyanobacteria are central to regulating the global climate and underpin entire marine food webs. Though they possess genes necessary to uptake diverse organic nutrients, we know very little about whether and how organic nutrients shape the physiology and ecology of cyanobacteria. Using our innovative high-throughput approach, this project aims to systematically characterise organic nutrient uptake in picocyanobacteria. Our molecules-to-ecosystems approach expects to transform our understanding of alternate nutrient acquisition in cyanobacteria and how it may shape populations of these important photosynthetic organisms in a rapidly-changing ocean landscape.

Are Secreted Proteins determinants of host range in ectomycorrhizal fungi? This project aims to understand the role of small secreted proteins in governing symbiotic fungal-host compatibility and determine the impact of environmental change on the role of these proteins. Using innovative approaches, this project expects to achieve these goals using comparative genomics, transcriptomic analyses and functional characterisation of these proteins within a keystone Australian ectomycorrhizal fungus. ....Are Secreted Proteins determinants of host range in ectomycorrhizal fungi?

Using innovative approaches, this project expects to achieve these goals using comparative genomics, transcriptomic analyses and functional characterisation of these proteins within a keystone Australian ectomycorrhizal fungus. It is anticipated that outcomes of this project will add a critical component to the global effort in understanding the role of soil microbes in supporting the health of plants experiencing a variety of climactic conditions. This could provide significant benefits to informing management practices of forest ecosystems.Read moreRead less

Building virtual cyanobacteria: moving beyond the genomics era. This project aims to establish a new understanding of complex biological systems through the development of computational models of single cells and global ecosystems. The project will focus on globally important photosynthetic bacteria that underlie the entire marine food web. This project aims to characterise the diversity and abundance of photosynthetic bacteria across Australia's marine habitats and unravel the genetic basis for their adaptation to different environments. This data will be integrated with biochemical and physiological studies to create quantitative models at the cellular and global ecosystem scales. This project aims to develop new biomonitoring technologies, which combined with these models, will enable assessment of the health of Australia's marine ecosystems.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?

Summary
The role of deep-sea microorganisms in nutrient cycling in the Southern Ocean. This project aims to learn how surface water microbes that are important in global nutrient cycling adapt to life when they sink to the deep sea. This will teach us about the roles that surface water and deep sea microbes play in maintaining the health of marine environments.
New tools to decipher, predict and manage pacific oyster mortality episodes. This project aims to unite cutting-edge genomic and molecular biological tools with novel quantitative modelling analyses to identify the mechanisms behind oyster disease events. Oyster farming contributes almost $100 million to the Australian economy each year and is a cornerstone of coastal communities, but has been decimated by diseases that threaten this important primary industry.

This project aims to unite cutting-edge genomic and molecular biological tools with novel quantitative modelling analyses to identify the mechanisms behind oyster disease events. Oyster farming contributes almost $100 million to the Australian economy each year and is a cornerstone of coastal communities, but has been decimated by diseases that threaten this important primary industry. While some causative pathogens have been identified, the environmental catalysts of oyster disease remain a mystery. The expected outcome of this project is an innovative coupling of tools that provides new capacity to forecast disease events, delivering the Australian oyster industry a powerful platform to predict, manage and prevent costly disease outbreaks. By identifying environmental thresholds and oyster disease danger periods, an expected outcome of this project is the development of new oyster farming strategies aimed at avoiding multi-million dollar losses associated with disease outbreaks.Read moreRead less
