The paper models ecological dynamics in marine oxygen minimum zones to explain the prevalence of different denitrification modules and their implications for nitrogen loss.

The paper identifies a new bacterial phylum, Candidatus Nitrosediminicolota, which oxidizes nitrite and resolves the abundance imbalance between ammonia-oxidizing archaea and canonical nitrite-oxidizing bacteria in marine sediments.

This study reports 33 new metagenome-assembled genomes of DPANN archaea from marine oxygen deficient zones, revealing their abundance, distribution, and potential roles in biogeochemical cycles.

The paper identifies two novel Scalindua genomes from oxygen deficient zones, revealing their metabolic versatility and evolutionary adaptation to anoxic environments.
