The Biodiversity of the Mediterranean Sea: Estimates, Patterns, and Threats
The Mediterranean Sea is a marine biodiversity hot spot. Here we combined an extensive literature analysis with expert opinions to update publicly available estimates of major taxa in this marineExpand

Structure and function of the global ocean microbiome
Microbes are dominant drivers of biogeochemical processes, yet drawing a global picture of functional diversity, microbial community structure, and their ecological determinants remains a grandExpand

Significance of Size and Nucleic Acid Content Heterogeneity as Measured by Flow Cytometry in Natural Planktonic Bacteria
ABSTRACT Total bacterial abundances estimated with different epifluorescence microscopy methods (4′,6-diamidino-2-phenylindole [DAPI], SYBR Green, and Live/Dead) and with flow cytometry (Syto13)Expand

Biomass distribution in marine planktonic communities
Patterns in primary production and carbon export from the euphotic zone suggest that the relative contribution of planktonic heterotrophs to community biomass should decline along gradients ofExpand

Microbial oceanography of the dark ocean's pelagic realm
The pelagic realm of the dark ocean represents a key site for remineralization of organic matter and long-term carbon storage and burial in the biosphere. It contains the largest pool of microbes inExpand

Dissolved Primary Production and the Strength of Phytoplankton– Bacterioplankton Coupling in Contrasting Marine Regions
We analyzed the strength of phytoplankton–bacterioplankton coupling by comparing the rate of particulate (PPP) and dissolved primary production (DPP) with bacterial carbon demand (BCD) in fourExpand

Patterns and ecological drivers of ocean viral communities
Viruses influence ecosystems by modulating microbial population size, diversity, metabolic outputs, and gene flow. Here, we use quantitative double-stranded DNA (dsDNA) viral-fraction metagenomesExpand

Winter-to-summer changes in the composition and single-cell activity of near-surface Arctic prokaryotes.
We collected surface samples in Franklin Bay (Western Arctic) from ice-covered to ice-free conditions, to determine seasonal changes in the identity and in situ activity of the prokaryoticExpand

Seasonality in bacterial diversity in north-west Mediterranean coastal waters: assessment through clone libraries, fingerprinting and FISH.
We combined denaturing gradient gel electrophoresis (DGGE), catalysed reporter deposition-FISH (CARD-FISH) and clone libraries to investigate the seasonality of the bacterial assemblage compositionExpand

Ecogenomics and potential biogeochemical impacts of globally abundant ocean viruses
Ocean microbes drive biogeochemical cycling on a global scale. However, this cycling is constrained by viruses that affect community composition, metabolic activity, and evolutionary trajectories.Expand
