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 ...
Nitrogen cycling in coastal marine ecosystems 喜欢 0 阅读量: 370 作者: RA Herbert 摘要: It is generally considered that nitrogen availability is one of the major factors regulating primary production in temperate coastal marine environments. Coastal regions often receive large anthropogenic inputs of ...
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...
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...
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, ...
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...
