The aim of the project is to examine structural and functional microbiome dynamics in an ecologically important coral on the Great Barrier Reef along a natural temperature gradient. Microorganisms form an intimate symbiotic relationship with corals and are critical to their health. However, the microbiome can be disrupted by environmental perturbations, including higher-than-normal ocean temperatures, leaving the coral susceptible to disease and bleaching. Currently, our understanding of how the microbiome composition and metabolic function change in response to seasonal temperature variation and disease is limited. This project is designed to provide insight into the role the microbiome plays in maintaining coral health and may aid in the long-term preservation of the reefs.Read moreRead less
The mobilome of the anaerobic methanotrophic archaea Methanoperedenaceae. Microorganisms play a critical role in regulating Earth’s climate, but how they are affected by our rapidly changing environment is not well understood. This Discovery project will study a group of microorganisms found in freshwater sediment that can consume the potent greenhouse gas methane before it is released into the atmosphere. We have developed new methods to investigate how genetic material is exchanged between mic ....The mobilome of the anaerobic methanotrophic archaea Methanoperedenaceae. Microorganisms play a critical role in regulating Earth’s climate, but how they are affected by our rapidly changing environment is not well understood. This Discovery project will study a group of microorganisms found in freshwater sediment that can consume the potent greenhouse gas methane before it is released into the atmosphere. We have developed new methods to investigate how genetic material is exchanged between microorganisms, and how this helps them adapt to environmental changes. Together, this will ultimately help us develop better climate change prediction models and contribute to our understanding of microbial communities that are crucial for environmental health.Read moreRead less
Atmospheric carbon fixation: a novel microbial process in Antarctic soils. This project aims to challenge our global understanding of carbon fixation. In most ecosystems, phototrophy supports higher-trophic life, yet no genetic evidence for photosynthesis exists in Antarctic desert soils. The project will determine the significance of atmospheric chemotrophy, a microbial driven process based on the consumption of atmospheric gases that it is proposed supports energy maintenance and biomass assim ....Atmospheric carbon fixation: a novel microbial process in Antarctic soils. This project aims to challenge our global understanding of carbon fixation. In most ecosystems, phototrophy supports higher-trophic life, yet no genetic evidence for photosynthesis exists in Antarctic desert soils. The project will determine the significance of atmospheric chemotrophy, a microbial driven process based on the consumption of atmospheric gases that it is proposed supports energy maintenance and biomass assimilation in nutrient-starved Antarctic desert soils. Additionally, the project will establish if these processes are structuring soil microbial communities, particularly in response to climate change. The expected project outcome is knowledge of primary production at the nutritional limits of life. This should provide significant benefit, such as a shift in our knowledge of the biological sciences as a new minimalistic mode of primary production.Read moreRead less
Tracking the molecular dynamics of adaptation with horizontal gene transfer. This project aims to track the dynamics of adaptation with gene exchange by building the first experimental evolution model that can directly observe this process. The acquisition of genes from other strains and species (horizontal gene transfer) frequently underlies bacterial adaptation, but it is unknown how this occurs. This project aims to shift understanding of how microbial populations respond to environmental cha ....Tracking the molecular dynamics of adaptation with horizontal gene transfer. This project aims to track the dynamics of adaptation with gene exchange by building the first experimental evolution model that can directly observe this process. The acquisition of genes from other strains and species (horizontal gene transfer) frequently underlies bacterial adaptation, but it is unknown how this occurs. This project aims to shift understanding of how microbial populations respond to environmental challenges. There are significant benefits to be gained from understanding how microbes adapt in response to climate change and the widespread application of antibiotics, given that microbial populations form intimate associations with humans and sustain all of the world’s ecosystems.Read moreRead less
Improved management of coastal plankton systems by ancient DNA technology. This project aims to assemble comprehensive long term Australian plankton records spanning 50 to 1000 years, by applying ancient DNA technology to dated sediment depth cores. Long-term data for Australian coastal and estuarine waters are sparse, so cannot be used for management of fisheries, tourism or urban development. Long-term records are essential to understand how disruptive algal and jellyfish blooms, introduced sp ....Improved management of coastal plankton systems by ancient DNA technology. This project aims to assemble comprehensive long term Australian plankton records spanning 50 to 1000 years, by applying ancient DNA technology to dated sediment depth cores. Long-term data for Australian coastal and estuarine waters are sparse, so cannot be used for management of fisheries, tourism or urban development. Long-term records are essential to understand how disruptive algal and jellyfish blooms, introduced species and increased human use of coastal resources affect dynamic plankton ecosystems. This project’s findings are expected to explore cyclical patterns, define range expansions and understand and manage how dynamic coastal ecosystems respond to multistressor anthropogenic change. Findings will improve understanding of how dynamic marine environments retain their biodiversity values and critical ecological functions.Read moreRead less
Experimental co-evolution of Yeast and E. coli. This project aims to measure the rates and genetic mechanisms of adaptation for individual species within a microbial community. Expected outcomes of this interdisciplinary project include the first genomic and phenotypic dataset of a model microbial community, and novel tools for the analysis of meta-genomic datasets. This project has the potential to transform understanding of microbial adaptation.
Lifestyle choices: genomic analysis of niche adaptations in marine Synechococcus. Photosynthetic marine bacteria are very important in the global carbon cycle. This project aims to discover how these bacteria adapt to survive in different marine environments. This is important for understanding how they will be affected by climate change and other environmental alterations.
Enhanced coral stress tolerance via manipulation of prokaryotic symbionts. The project aims to develop a novel approach to improve environmental stress tolerance in corals. Coral reefs are under threat from a range of stressors that have led to massive declines in coral cover and health worldwide. There is now great concern that the rate of environmental change is outpacing the natural capacity of corals to acclimatise, adapt and survive. Although it is important to address the root causes of cl ....Enhanced coral stress tolerance via manipulation of prokaryotic symbionts. The project aims to develop a novel approach to improve environmental stress tolerance in corals. Coral reefs are under threat from a range of stressors that have led to massive declines in coral cover and health worldwide. There is now great concern that the rate of environmental change is outpacing the natural capacity of corals to acclimatise, adapt and survive. Although it is important to address the root causes of climate change, a focus on strategies to mitigate its impacts is also required. This project explores the potential to augment the capacity of corals to tolerate stress through the manipulation of their associated prokaryotic communities. This project may result in novel coral reef restoration approaches.Read moreRead less

Summary
A high-throughput screening and sequencing facility for single cell genomics. Genomics has revolutionised biology, but for most microorganisms this revolution has not arrived because very few can be grown in pure culture. The single cell genomics facility will address this major bottleneck by allowing as little as a single cell in a clinical or environmental setting to be sequenced thereby accelerating new discoveries and outcomes.
