Ammonia-oxidizing Archaea (AOA) are ubiquitous throughout the oceanic water column;
however, our knowledge on their physiological and ecological diversity in different oceanic …

This paper synthesizes recent findings regarding microbial distributions and processes in
the bathypelagic ocean (depth> 1000m). Abundance, production and respiration of …

Proteins in the open ocean represent a significant source of organic matter, and their profiles
reflect the metabolic activities of marine microorganisms. Here, by analyzing metaproteomic …

Marine Thaumarchaeota are abundant ammonia‐oxidizers but have few representative
laboratory‐cultured strains. We report the cultivation of Candidatus Nitrosomarinus catalina …

Urea accounts for∼ 50% of global nitrogen (N)‐based fertiliser; however, little is known of
the factors regulating its distribution and abundance in freshwaters. Improved understanding …

In order to characterize the carbon biomass spatial distribution of autotrophic and
heterotrophic picoplankton populations linked to mesoscale dynamics, an investigation over …

Nitrogen (N) is the major limiting nutrient for phytoplankton growth and productivity in large
parts of the world's oceans. Differential preferences for specific N substrates may be …

Giant clams live in nutrient-poor reef waters of the Indo-Pacific and rely on symbiotic
dinoflagellates (Symbiodinium spp., also known as zooxanthellae) for nutrients. As the …

This study optimized the experimental conditions for the analysis of dissolved urea in
seawater. The kinetics of the colorimetric reaction of urea with diacetyl monoxime were …

Nitrogen (N), as a critical element for microbial metabolisms, recycles rapidly in the euphotic
ocean. Oxidation by nitrifiers is a competing pathway for phytoplankton assimilation of …
