Drivers and consequences of freshwater microbial community change

Freshwater ecosystems are ‘hot spots’ of biogeochemical cycling driven by the many diverse and interacting microbial communities that inhabit them. Understanding the drivers that regulate the diversity and composition of freshwater microbial communities and the ecosystem processes they carry out in time and space is therefore of pivotal importance.

In this session we invite a broad range of presentations that focus on drivers that affect the diversity and composition of freshwater microbiomes and biogeochemical processes, going beyond descriptive ‘omics’ inventories. This includes studies that focus on linkages and interactions, such as between freshwater and surrounding terrestrial ecosystems, and among different groups of (micro)organisms. We also specifically welcome presentations on effects of anthropogenic environmental change and disturbances across spatial and temporal scales, the role of aquatic invasive species in (re)structuring microbial food webs, and examples of biogeochemical processes that have ecosystem-scale implications.
