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

This project aims to develop microbes which are able to enhance the climate resilience of corals. Coral reefs around the world are being lost at an alarming rate. Developing microbial symbionts to enhance coral climate resilience will give Australian and other coral reef ecosystems an increased chance of surviving the impact of climate change. The project will also enhance understanding of the functional roles of microbial symbionts of corals, and advance the microbial symbiosis discipline globally. Expected outcomes include healthier coral reefs through the use of more climate resilient coral stock in reef conservation and restoration initiatives.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.

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
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. As global temperate reefs respond to ocean warming, iconic and economically important kelp forests and associated fishes and invertebrates are being lost.

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

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
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.

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
Defining and engineering the rhizosphere for Australian rainfall patterns. The manner in which plants use carbon and water defines agricultural and natural landscapes. Today's models that predict plant improvement rely on carbon and water usage by plant leaves. However, the first interaction between plants, carbon and water occurs in the rhizosphere; a diverse zone with dynamic root-microbiome interactions.

The manner in which plants use carbon and water defines agricultural and natural landscapes. Today's models that predict plant improvement rely on carbon and water usage by plant leaves. However, the first interaction between plants, carbon and water occurs in the rhizosphere; a diverse zone with dynamic root-microbiome interactions. We will use advanced visualisation and mathematics to determine fine scale relationships between microbes and roots in the rhizosphere when exposed to water levels reflective of current and projected rainfall values. From generated knowledge of water and carbon dynamics caused by intimate microbe-root interactions, we will provide water saving, soil regeneration and improved carbon biosequestration strategies.Read moreRead less

Summary
A unique and overlooked microbial process scavenging two greenhouse gases. This project aims to perform the first-ever systematic investigation of a novel microbial process, in which two potent gases (methane and nitric oxide) responsible for the climate change are metabolized simultaneously. This process is suggested to be universal in early and modern Earth's aquatic systems, which is a potential but overlooked microbial sink for methane and nitric oxide. By identifying the responsible organis ....A unique and overlooked microbial process scavenging two greenhouse gases. This project aims to perform the first-ever systematic investigation of a novel microbial process, in which two potent gases (methane and nitric oxide) responsible for the climate change are metabolized simultaneously. This process is suggested to be universal in early and modern Earth's aquatic systems, which is a potential but overlooked microbial sink for methane and nitric oxide. By identifying the responsible organisms and their metabolic pathway, this project represents a critical step towards a full understanding of their roles in affecting the greenhouse gas emission. This understanding will also enable us to more reliably predict the global climate change, which is one of the most significant challenges in the 21st Century.Read moreRead less
