Macroecological patterns of archaeal ammonia oxidizers in the Atlantic Ocean

Macroecological patterns are found in animals and plants, but also in micro-organisms.Macroecological and biogeographic distribution patterns in marine Archaea, however,have not been studied yet. Ammonia-oxidizing Archaea (AOA) show a bipolar distribution(i.e. similar communities in the northernmost and the southernmost locations,separated by distinct communities in the tropical and gyral regions) throughout theAtlantic, detectable from epipelagic to upper bathypelagic layers (
