Polysaccharides are major components of macroalgal and phytoplankton biomass and
constitute a large fraction of the organic matter produced and degraded in the ocean. Until …

The “biological pump” is the process by which photosynthetically-produced organic matter in
the ocean descends from the surface layer to depth by a combination of sinking particles …

The sinking of organic particles formed in the photic layer is a main vector of carbon export
into the deep ocean. Although sinking particles are heavily colonized by microbes, so far it …

Marine oxygen minimum zones (OMZs) support diverse microbial communities with roles in
major elemental cycles. It is unclear how the taxonomic composition and metabolism of OMZ …

Our limited intuition of the small‐scale world of the plankton has biased the way we describe
and understand ocean ecology. Classical approaches consider fluxes of energy and matter …

In recent years, microbial ecology has developed from a peripheral discipline into a central
field of microbiology. This change in state and perception is mainly driven by a rapid …

Sediment in a water column provides excellent substratum for microorganism colonization,
and biological processes would alter the physical and chemical of sediment, resulting in …

The genetic composition of marine microbial communities varies at the microscale between
particle-associated (PA;> 1.6 μm) and free-living (FL; 0.2–1.6 μm) niches. It remains unclear …

Colonies of N2-fixing cyanobacteria are key players in supplying new nitrogen to the ocean,
but the biological fate of this fixed nitrogen remains poorly constrained. Here, we report on …

Marine and limnic particles are hotspots of organic matter mineralization significantly
affecting biogeochemical element cycling. Fluorescence in‐situ hybridization and …
