The paper shows that microbial diversity in river biofilms predicts resistance to invasion by antibiotic-resistant bacteria, with higher diversity reducing the likelihood of establishment.

This study tracks antimicrobial resistance gene (ARG) distribution along Switzerland's Aare River, showing increased ARG abundance downstream due to wastewater treatment plant effluents.

The paper identifies active microbial communities and extrachromosomal elements in anoxic sediments, linking organic matter degradation to methane cycling through fermentation and methanogenesis.
