Microbes play fundamental roles in shaping natural ecosystem properties and functions, but do so under constraints imposed by their viral predators. However, studying viruses in nature can be challenging due to low biomass and the lack of universal gene markers. Though metagenomic short-read sequencing has greatly improved our virus ecology toolkit-and revealed many critical ecosystem roles for viruses-microdiverse populations and fine-scale genomic traits are missed.

- Microorganisms in the Prairie Pothole Region play a crucial role in methanogenesis and carbon mineralization, with notable rates of sulfate reduction and methane emissions found in wetland sediments.
- Researchers utilized metagenomics to uncover diverse candidate sulfate reducers and methanogens, identifying potential metabolic pathways involving various electron donors and highlighting the role of alcohols in methane production.
- A significant presence of novel viral populations was discovered, many of which are likely to interact with key microbial players, suggesting complex ecological dynamics in these wetland systems.
