Marine diazotrophs convert dinitrogen (N 2) gas into bioavailable nitrogen (N), supporting
life in the global ocean. In 2012, the first version of the global oceanic diazotroph database …

In the last decade, the known biogeography of nitrogen fixation in the ocean has been
expanded to colder and nitrogen‐rich coastal environments. The symbiotic nitrogen‐fixing …

Marine diazotrophs convert dinitrogen (N 2) in seawater into bioavailable nitrogen (N),
contributing approximately half of the external input of bioavailable N to the global ocean. A …

The environmental regulation of planktonic food web structure is a key determinant for the
efficiency of energy transfer through trophic levels, with direct implications for the amount of …

The classical paradigm about marine N2 fixation establishes that this process is mainly
constrained to nitrogen-poor tropical and subtropical regions, and sustained by the colonial …

We investigated dinitrogen (N2) fixation activity and diazotroph community composition
across the Cape Verde Frontal Zone (CVFZ), from photic epipelagic waters (0-200 m) to …

Opposing opinions on the importance of nitrogen fixation in the northern Benguela
upwelling region provoked us to investigate the magnitude of nitrogen fixation in front of …

This chapter describes the Benguela upwelling system along the western coast of southern
Africa and its interactions with the tropical ocean to the north and the Agulhas Current to the …

The distribution of zooplankton biomass and potential metabolic rates, in terms of electron
transport system (ETS) and glutamate dehydrogenase (GDH), were analyzed along a cross …

Freshly upwelled water is poor in phytoplankton biomass but rich in nutrients. With its
ageing, phytoplankton biomass increases whereas the nutrients are consumed. The overall …
