Biological N2 fixation is an important part of the marine nitrogen cycle as it provides a source
of new nitrogen that can support biological carbon export and sequestration. Research in …

Discrepancies between estimates of oceanic N 2 fixation and nitrogen (N) losses through
denitrification have focused research on identifying N 2-fixing cyanobacteria and quantifying …

Marine N 2 fixing microorganisms, termed diazotrophs, are a key functional group in marine
pelagic ecosystems. The biological fixation of dinitrogen (N 2) to bioavailable nitrogen …

Nitrogen (N) is a key element for life in the oceans. It controls primary productivity in many
parts of the global ocean, consequently playing a crucial role in the uptake of atmospheric …

The two commonly applied methods to assess dinitrogen (N2) fixation rates are the 15N2-
tracer addition and the acetylene reduction assay (ARA). Discrepancies between the two …

Here we describe the application of a new click chemistry method for fluorescent tracking of
protein synthesis in individual microorganisms within environmental samples. This …

Investigating the contribution of microbial populations to biochemical processes of global
significance is challenging as there are few approaches that can detect microbial metabolic …

Many marine organisms have coevolved symbiotic relationships with nitrogen-fixing bacteria
in nitrogen limited environments such as coral reefs. In addition, some of these organisms …

The Amazon River Plume spreads across the tropical North Atlantic creating a barrier to
vertical mixing. Here using a 1/6° HYCOM model and data from three research cruises in …

An astonishing diversity of microorganisms thrives on our planet and their activities are
fundamental for the functioning of all ecosystems including the human body. Consequently …
