PhD Project: The Role Of The Atmosphere In Shaping And Sustaining Microbial Communities On Glaciers
The atmosphere forms a bridge between Earth’s major biomes, shaping adjacent environments via processes that are not yet fully understood. Airborne microorganisms have been shown to be metabolically active despite the stressful conditions of the atmosphere, with flexible metabolic strategies enabling them to survive in variable or energy-deprived environments, expanding our notion of habitable environments and the physicochemical limits of life. Although research indicates that microbial communities are influenced by atmospheric deposition, contributions and functions of atmospheric inputs onto glaciers and ice sheet biomes remain poorly understood. As such, this project aims to assess the habitability potential of the atmosphere, particularly within its role in shaping microbiome composition in glacier habitats. We will explore how feasible it is for glacial communities to survive off atmospheric trace gases as an alternative source of energy given the physicochemical limitations of this environment.
