Light-driven integration of diazotroph-derived nitrogen in euphotic nitrogen cycle [PDF]
Nature CommunicationsThe bioavailable nitrogen fixed by diazotrophs is critical for sustaining productivity in the oligotrophic ocean. Despite this, understanding how diazotroph-derived nitrogen integrates into the nitrogen cycle within the euphotic zone remains unknown ...

The spatial distribution and biogeochemical drivers of nitrogen cycle genes in an Antarctic desert [PDF]
Frontiers in Microbiology, 2022 Antarctic deserts, such as the McMurdo Dry Valleys (MDV), represent extremely cold and dry environments. Consequently, MDV are suitable for studying the environment limits on the cycling of key elements that are necessary for life, like nitrogen.

Cyclic Conversions in the Nitrogen Cycle [PDF]
Frontiers in Microbiology, 2021 The cyclic nature of specific conversions in the nitrogen cycle imposes strict limitations to the conversions observed in nature and explains for example why anaerobic ammonium oxidation (anammox) bacteria can only use nitrite – and not nitrate – as ...

The element nitrogen is fundamental to life on Earth, including freshwater life. Catchments are a dominant source of nitrogen to freshwater, and human activities have accelerated the scale of these inputs. The atmosphere is also increasingly a source of nitrogen to freshwater.

Nitrogen Cycle in Farming Systems
Agronomy, 2023 The challenge for people currently living on Earth is to develop a food production strategy to cover the food gap and at the same time maintain or even improve the soil use production potential [...]

Current Biology, 2016 Nitrogen is the fourth most abundant element in cellular biomass, and it comprises the majority of Earth's atmosphere. The interchange between inert dinitrogen gas (N2) in the extant atmosphere and 'reactive nitrogen' (those nitrogen compounds that support, or are products of, cellular metabolism and growth) is entirely controlled by microbial ...

Nitrogen cycling in sheep [PDF]
Proceedings of the Nutrition Society, 1973 Introduction Many of the difficulties in predicting the response of ruminants to supplementation of low-protein diets with non-protein nitrogen (NPN) substances arise because there is a lack of information concerning the quantities of N that recycle between the tissues and the N pools in the digestive tract. Various aspects of N mctabolism in ruminants

Polar Research, 2020 Nitrate in snow is subject to post-depositional processing, which leads to a net loss and redistribution within the snowpack. The relative importance of post-depositional loss processes such as the volatilization of nitric acid (HNO3) and photolysis of ...

A Synthesis of Viral Contribution to Marine Nitrogen Cycling
Frontiers in Microbiology, 2022 Nitrogen is an essential component of major cellular macromolecules, such as DNA and proteins. Its bioavailability has a fundamental influence on the primary production of both terrestrial and oceanic ecosystems. Diverse marine microbes consume nitrogen,
