Fine-scale resolution of genomes in natural microbial communities. This project aims to develop advanced molecular and statistical techniques to precisely resolve the genomes of microbes in the environment. Microbes inhabit every niche on the planet and are fundamental to human and animal health, agriculture, and the environment. The proposed technology will advance our understanding of environmental microbes, leading to advances in areas like climate science and biosecurity where microbes play ....Fine-scale resolution of genomes in natural microbial communities. This project aims to develop advanced molecular and statistical techniques to precisely resolve the genomes of microbes in the environment. Microbes inhabit every niche on the planet and are fundamental to human and animal health, agriculture, and the environment. The proposed technology will advance our understanding of environmental microbes, leading to advances in areas like climate science and biosecurity where microbes play a key role. It will also support the development of billion dollar industries focused on the use of beneficial microbes in agriculture, plant, animal, and human health.Read moreRead less
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
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
Formation and stabilisation of coastal blue carbon. Blue carbon is organic carbon stored within coastal vegetated ecosystems. This project will examine the composition, formation and dynamics of blue carbon in a range of coastal ecosystems. Combining advanced analytical chemistry with environmental microbiology, we will discover how blue carbon is stabilised and destabilised, a critical factor in nature-based climate change mitigation strategies. Further, we will gain a quantitative understandin ....Formation and stabilisation of coastal blue carbon. Blue carbon is organic carbon stored within coastal vegetated ecosystems. This project will examine the composition, formation and dynamics of blue carbon in a range of coastal ecosystems. Combining advanced analytical chemistry with environmental microbiology, we will discover how blue carbon is stabilised and destabilised, a critical factor in nature-based climate change mitigation strategies. Further, we will gain a quantitative understanding of blue carbon contributions to carbon cycling, providing enhanced modeling and prediction of climate-cycle feedbacks in response to biotic and environmental change. This research will significantly benefit Australia’s effective management of coastal vegetated ecosystems for maximum carbon offsets.Read moreRead less
