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 aim of this project is to unveil the microbial biodiversity, novel metabolic capabilities and chemosynthetic primary production of subsurface ecosystems, such as those found in caves. Leveraging a powerful blend of geospatial, molecular and biogeochemical approaches this project expects to identify the microbial basis of subsurface biogeochemical processes driving the earth’s major elementary cycles. Expected outcomes include a predictive framework to assess and upscale the impact of these microbial communities on the environment. Benefits include predicting and responding to climate risks, such as the desertification of agricultural soils, by uncovering how microorganisms respond to nutrient and carbon depletion.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
Deciphering the coral minimal microbiome. This project aims to decipher the functions of coral-associated bacteria by taking advantage of low-diversity microbiomes that are naturally found in some coral species. A further aim is to unveil the importance of bacterial genome evolution in coral adaptation to climate change. Climate warming is the biggest threat to coral reefs with half of Australia’s Great Barrier Reef (GBR) corals dead due to recent summer heat waves. Expected outcomes are an incr ....Deciphering the coral minimal microbiome. This project aims to decipher the functions of coral-associated bacteria by taking advantage of low-diversity microbiomes that are naturally found in some coral species. A further aim is to unveil the importance of bacterial genome evolution in coral adaptation to climate change. Climate warming is the biggest threat to coral reefs with half of Australia’s Great Barrier Reef (GBR) corals dead due to recent summer heat waves. Expected outcomes are an increased understanding of how bacteria contribute to coral heat tolerance, and new knowledge to assist in the development of bacterial probiotics for enhancing coral thermal tolerance. This should provide significant benefits to the protection of the GBR and Australia’s economy.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.
An evolutionary landscape to better predict our future climate. Soil microbial communities are the most complicated and difficult to study on Earth, but their effects on our climate are profound. This project will examine the evolution of microorganisms and their viruses in soil using novel methods. It will uncover how the evolution of one microbial species influences the evolution of other community members. It will also apply a new model of evolution to the viruses that infect these microorgan ....An evolutionary landscape to better predict our future climate. Soil microbial communities are the most complicated and difficult to study on Earth, but their effects on our climate are profound. This project will examine the evolution of microorganisms and their viruses in soil using novel methods. It will uncover how the evolution of one microbial species influences the evolution of other community members. It will also apply a new model of evolution to the viruses that infect these microorganisms, constructing a viral ‘tree of life’. This improved fundamental understanding of soil communities will be used to study climate feedback from permafrost wetlands, a key and poorly constrained input of global climate models, improving predictions of our future climate.Read moreRead less

Summary
Annotating unknown microbial gene functions with organic matter change. This project intends to develop a new method for determining the function of microbial genomes. Microbes are all pervasive on Earth. It is now possible to routinely sequence microbial genomes. However, the function of most genes encoded on these genomes remains elusive, severely limiting our understanding of most ecosystems. This project seeks to develop new methods to assign function to uncharacterised genes, by correlating ....Annotating unknown microbial gene functions with organic matter change. This project intends to develop a new method for determining the function of microbial genomes. Microbes are all pervasive on Earth. It is now possible to routinely sequence microbial genomes. However, the function of most genes encoded on these genomes remains elusive, severely limiting our understanding of most ecosystems. This project seeks to develop new methods to assign function to uncharacterised genes, by correlating changes in metabolite abundance with gene expression in a model permafrost thaw peatland. Determining the function of uncharacterised genes has widespread implications for microbial ecology and its numerous real-world applications, from determining soil greenhouse gas emissions to understanding human intestinal flora.Read moreRead less
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.
Climate-driven windblown dust and flood runoff can increase marine diseases by fungal pathogens. Determination of the role of fungal pathogens in marine disease outbreaks, and their linkages to climate-driven dust and flood events, have important applications for coastal fisheries and the Great Barrier Reef. This project will develop molecular tools and plankton recorder protocols to detect fungal outbreaks and assess ecosystem resilience.
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
