This study uses a trait-based model to show how microbial facilitation and competition shape nitrogen cycling and biogeochemical outcomes in marine environments.

The paper shows how periodic oxygen intrusions sustain aerobic nitrite-oxidizing bacteria in anoxic marine zones, increasing microbial diversity and altering biogeochemical cycling.

The paper develops a model linking microbial ecology and redox chemistry to predict shifts in nitrogen loss versus retention in aquatic systems under eutrophication.

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