We sampled five locations of deep‐sea surface sediments in the central ice‐covered Arctic Ocean and documented diazotroph communities and nitrogen fixation potential. The findings considerably extend the known biome of marine nitrogen fixation and raise the question of the significance of low but potentially widespread nitrogen fixation in deep‐sea ...

Nitrogen Substrate Impacts Microcystis aeruginosa Exometabolome Composition
We used untargeted metabolomics to identify differences in the compounds exuded into culture media by three strains of M. aeruginosa grown on three N substrate treatments (NO3−, NH4+, and urea). Results showed that the usage of different N substrates changes the exometabolome of toxic and non‐toxic strains of M. aeruginosa.

In the English Channel, the main environmental variables were SPM, POM, PIM, NO2−/NO3+ and salinity in spring and salinity, SPM, Si and Chl‐a in summer. Most of the spring communities had a higher proportion of Bacteroidetes and Proteobacteria, while most of the summer communities had a higher proportion of Proteobacteria, Bacteroidetes, Actinobacteria,

Biodiversity in mountain soils above the treeline
ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...
