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.
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
The dynamics of evolution: How horizontal gene transfer drives the diversification and adaptation of complex, bacterial communities. The genetic exchange between populations is a prerequisite for the long-term evolution of bacteria, however its short-term dynamics are largely unexplored. This project aims to define the temporal dynamics of gene transfer and how it shapes the genetic composition of entire bacterial communities. Using innovative DNA sequencing technologies and bioinformatics, This ....The dynamics of evolution: How horizontal gene transfer drives the diversification and adaptation of complex, bacterial communities. The genetic exchange between populations is a prerequisite for the long-term evolution of bacteria, however its short-term dynamics are largely unexplored. This project aims to define the temporal dynamics of gene transfer and how it shapes the genetic composition of entire bacterial communities. Using innovative DNA sequencing technologies and bioinformatics, This project aims to offer a significant new understanding of the short-term diversification of communities and how different evolutionary forces shape bacterial function. It will show how bacterial systems can adapt to new environmental conditions and the effect on essential ecosystem functions.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.
