Micro-scale organization of non-cyanobacterial diazotrophs drives nitrogen fixation in marine particles

Dinitrogen (N₂) fixation supplies reactive nitrogen to the ocean, and non-cyanobacterial diazotrophs (NCDs) are increasingly recognized as contributors. Marine particles have been theorized as hotspots where low oxygen and labile carbon favor N₂ fixation by NCDs, but empirical proof is lacking. Here, we show that p...
