Analysis of the spatial distributions of MAGs showed distinct site-specific compositions of bacteria and archaea capable of nitrogen cycling (Fig.3), a feature also observed in groundwater microbial communities as a whole [13]. Bray–Curtis dissimilarities, calculated based on relative abundance for ...
(redirected fromNitrogen cycling) Thesaurus Medical Encyclopedia nitrogen cycle n. The circulation of nitrogen in nature, consisting of a cycle of chemical reactions in which nitrogen from the atmosphere is fixed in compounds in soil or water, assimilated by plants and animals, released to the soil...
runoff and levels of pollutants. Therefore it is important to continue to gain more insight into nitrogen cycling in coral reefs ecosystems as the ability of coral reefs to “adapt to these perturbations in the past is no guarantee of resilience in the future” (Hughes, 1994). We must, as...
N-cycling functional diversity of the crab’s carapace microbiome Most of the metagenome reads were attributed to the Gene Ontology categories: metabolic processes, transport, and catalytic activity (Fig.2a). Among metabolic processes, the main subcategories were those related to aerobic respiration, ...
cycling of nitrogen. These latter processes lead to a loss of usable fixed nitrogen from the soil. Overall, the input rate from biological, spontaneous (e.g., lightning), and industrialnitrogen fertilizer(by the Haber–Bosch process) production is slightly higher than the loss rate. Of these,...
experimental and field research designs must consider both. We suggest future research to characterize additives, especially in controlled studies of organismal responses, so that their influence can be better assessed. If certain additives are found to inhibit coastal N cycling, their use in plastics...
In this Review, we describe carbon and nitrogen cycling on the QTP. Overall, the QTP has been a net carbon sink (with a net carbon balance of ~44 million tons of carbon uptake per year) and a methane source (~0.96 trillion grams per year of carbon in the form of methane, Tg...
Productivity in the marine environment is ultimately controlled by the cycling of nitrogen, phosphorus, iron, and other bio-limiting trace elements. The degree to which nutrient cycling and marine productivity will be affected by future warming scenarios remains unclear, but the effects can be reveale...
CyanobacteriaandProteobacteria, or in unclassified archaeal viruses predicted to infectThaumarchaeota. Four AMGs were exclusive to anoxic waters and had distributions that paralleled homologous microbial genes. Together, these findings suggest viruses modulate N-cycling processes within the ETSP OMZ and ...
