This study shows heatwave conditions alter active nitrifying communities and their viruses in tidal flats and agricultural soils, affecting nutrient cycling.

The paper examines microbial community diversity in a uranium-contaminated aquifer, finding reduced taxonomic and phylogenetic diversity but stable functional diversity.

This study identifies pathway partitioning as a mechanism for complete denitrification in microbial communities and shows how imbalances in substrate utilization can disrupt cooperativity and lead to nitrous oxide emissions.

This study investigates how genomic and environmental factors influence the distribution of Castellaniella species in a contaminated subsurface, identifying genetic mechanisms underlying their adaptation to stress.

The paper shows that ammonia-oxidizing microorganisms use different regulatory strategies for ammonia and urea, enabling coexistence by minimizing competition.

This study examines microbial traits involved in B12 biosynthesis in the global ocean, revealing that environmental factors select functional traits over taxonomy and that functional redundancy drives community assembly.

The paper characterizes subsurface media from contaminated and background sites to understand biogeochemical interactions and microbial activity.
