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.
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
Evolution of the marsupial gut microbiome and adaptation to eucalypt toxins. Eucalyptus leaves comprise all or part of the diet of some marsupials including koalas. Gut microbiota assist in the ability of these folivores to tolerate eucalyptus toxins although present understanding of this process is rudimentary. This project aims to use culture-independent molecular methods to identify and characterise gut populations involved in phytochemical detoxification by comparative analysis with diprotod ....Evolution of the marsupial gut microbiome and adaptation to eucalypt toxins. Eucalyptus leaves comprise all or part of the diet of some marsupials including koalas. Gut microbiota assist in the ability of these folivores to tolerate eucalyptus toxins although present understanding of this process is rudimentary. This project aims to use culture-independent molecular methods to identify and characterise gut populations involved in phytochemical detoxification by comparative analysis with diprotodont relatives that are not capable of digesting eucalyptus leaves. This will highlight evolutionary convergence of gut microbiomes in toxic folivores and reveal mechanisms by which microorganisms respond to and metabolise eucalypt toxins. A broader evolutionary context of marsupial digestive function will assist in ongoing conservation efforts.Read moreRead less
Revealing the structure, evolution and sensitivity of symbioses in basal metazoa. This project will explore the complex interactions between each component of the sponge holobiont (virus, bacteria, sponge) during thermal stress. This will also provide the first molecular assessment of sponge viruses and provide insights into how sponges may adapt to a changing climate.
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
Global integration of microbial community and climate data. Microbial communities in the environment control the cycling of carbon and nutrients on Earth, but climate models do not directly incorporate microbial inputs. This interdisciplinary project will link planetary-scale climate modelling data with novel large-scale microbial community analysis, using climate information to provide insight into the fantastic diversity of microbial processes on our planet. The interdisciplinary approach will ....Global integration of microbial community and climate data. Microbial communities in the environment control the cycling of carbon and nutrients on Earth, but climate models do not directly incorporate microbial inputs. This interdisciplinary project will link planetary-scale climate modelling data with novel large-scale microbial community analysis, using climate information to provide insight into the fantastic diversity of microbial processes on our planet. The interdisciplinary approach will inform the next generation of climate models and better predict our future climate’s feedbacks. Conversely, it will make progress on the grand challenge of understanding microbial community function by enabling microbial ecology to be treated as a data-intensive machine learning problem.Read moreRead less

This national and international icon needs to be preserved in the face of a changing world to ensure on-going sustainability of our marine resources. Ocean acidification, warming water temperatures, increased freshwater disrupt the sensitive symbiotic association of corals the major structure building organisms of reefs. Understanding how these environmental stressors result in the decrease in coral health is fundamental to prevent loss of our coral reefs and an important step towards preserving them for future generations.Read moreRead less
Genome-level insight into the dynamics of a model coral microbiome. 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 susceptib ....Genome-level insight into the dynamics of a model coral microbiome. 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
Adaptive ecotyping of the toxic cyanobacterium Cylindrospermopsis raciborskii to predict its invasive capacity. We change the world while other organisms adapt to these new conditions. Cyanobacteria (blue green algae) increasingly dominate water bodies that were previously free of these harmful blooms. To minimise the spread of these algae, this project will study the genetic basis that determines how rapidly they can evolve and adapt to a changing planet.
