Global patterns of bacterial beta-diversity in seafloor and seawater ecosystems.

<h4>Background</h4>Marine microbial communities have been essential contributors to global biomass, nutrient cycling, and biodiversity since the early history of Earth, but so far their community distribution patterns remain unknown in most marine ecosystems.<h4>Methodology/princip...
