Significance of gene variants for the functional biogeography of the near-surface Atlantic Ocean microbiome
Abstract Microbial communities are major drivers of global elemental cycles in the oceans due to their high abundance and enormous taxonomic and functional diversity. Recent studies assessed microbial taxonomic and functional biogeography in global oceans but microbial functional biogeography remain...
