To eat or not to eat? How symbiotic bacteria manipulate the phagocytic behaviour of their eukaryotic host. Bacteria often live in close association with eukaryotic cells, ranging from simple amoeba to humans. This project will identify key factors that control their interactions and will yield important information on the evolution of beneficial or harmful relationships.
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
Mitigating the risk of cyanobacterial blooms in wastewater ponds. Cyanobacterial blooms in wastewater treatment plants impact on effluent quality and the utility of recycled water, posing a significant risk to the economy, the environment and public health. To understand the causes of cyanobacterial blooms in pond-based wastewater treatment plants and the risk they pose, this project will use the latest molecular techniques to examine how the microbial communities within these systems interact w ....Mitigating the risk of cyanobacterial blooms in wastewater ponds. Cyanobacterial blooms in wastewater treatment plants impact on effluent quality and the utility of recycled water, posing a significant risk to the economy, the environment and public health. To understand the causes of cyanobacterial blooms in pond-based wastewater treatment plants and the risk they pose, this project will use the latest molecular techniques to examine how the microbial communities within these systems interact with each other and their surrounding environment to form blooms and produce toxins and other harmful metabolites. Such knowledge will inform risk assessment and provide strategies for the mitigation of future bloom events, improving the security of our increasingly valuable recycled water resources.Read moreRead less
What do Microorganisms do Season by Season, Year after Year in the Frigid Antarctic Wilderness? Antarctica is arguably the world’s most important continent for influencing the Earth’s climate and global ocean ecosystem. Like most natural aquatic environments on Earth, in Antarctica microorganisms dominate the genetic pool and biomass and play the key roles in maintaining proper ecosystem function. The project aims to determine how microbial communities change throughout a complete annual cycle i ....What do Microorganisms do Season by Season, Year after Year in the Frigid Antarctic Wilderness? Antarctica is arguably the world’s most important continent for influencing the Earth’s climate and global ocean ecosystem. Like most natural aquatic environments on Earth, in Antarctica microorganisms dominate the genetic pool and biomass and play the key roles in maintaining proper ecosystem function. The project aims to determine how microbial communities change throughout a complete annual cycle in three climate sensitive, Antarctic lakes. By establishing what the microorganisms do in different seasons the study will learn which microbial processes change and how environmental perturbation will impact on normal ecological cycles. This will form the basis for evaluating the effects of climate change on sensitive ecosystems in the Antarctic.Read moreRead less
