Abstract Mesoscale eddies in Oxygen Minimum Zones (OMZs) have been identified as
important fixed nitrogen (N) loss hotspots that may significantly impact both the global rate of …

The quantity and quality of organic matter (OM) available for macrobenthos vary on temporal
and spatial scale, especially in coastal areas, where the seafloor is supplied by both …

The stable nitrogen isotope (15 N) analysis of ammonium (NH4+) and nitrate (NO3–) is
widely used in ecological research, providing insights into N cycling and its underlying …

Chemolithoautotrophic denitrification is an important mechanism of nitrogen loss in the
water column of euxinic basins, but its isotope fractionation factor is not known. Sulfurimonas …

Nitrification and denitrification are traditionally assumed to occur under aerobic and anoxic
conditions, respectively. However, new and interesting alternatives challenge the traditional …

The mechanism governing sulfur cycling in nitrate reduction within sulfate-rich reservoirs
during seasonal hypoxic conditions remains poorly understood. This study employs nitrogen …

Fixed nitrogen is a limiting nutrient in many marine environments. Only a subset of the
microbial community has the ability to fix dinitrogen gas (N 2). Here, we document the …

Abstract Knowledge of how zooplankton can utilize cyanobacteria to sustain their nitrogen
(N) demand for essential compounds like amino acids (AA s) is a key to predicting …

This paper elucidates the oxygen dynamics in the northern Benguela Upwelling System by
means of process oriented, numerical modelling. Owing to the complex physical-biological …

Viable indicators of nitrogen (N) attenuation at the catchment scale are needed in order to
sustainably manage global agricultural intensification. We hypothesized that the dominance …
