The Ecology of the Nitrogen Cycle The aim of this book is to present a concise summary of the current situation with respect to nitrogen cycling research. There are two parts, general featu... JI Sprent - 《Quarterly Review of Biology》 被引量: 332发表: 1987年 Induction of ornithine-urea...
Finally, it discusses the anthropogenic perturbation of the marine nitrogen cycle. As it examines, however, the answers to many of these questions remain elusive, reminding us how little we know about the marine nitrogen cycle, and how much still remains to be discovered. Although the marine ...
The impacts of enhanced nitrogen (N) deposition on the global forest carbon (C) sink and other ecosystem services may depend on whether N is deposited in reduced (mainly as ammonium) or oxidized forms (mainly as nitrate) and the subsequent fate of each. However, the fates of the two key...

2022). However, the comparison between Venus and Earth is complicated by the fact that the nitrogen cycle is modulated by Earth’s biosphere (Jacob 1999; Zerkle and Mikhail 2017). Sulfur dioxide is the third most abundant gas in the atmosphere of Venus. In contrast to N2, SO2 is extremely...
anammox, and the remaining amount is removed by other nitrogen cycle bacteria. The NH4+, NO2−, and NO3−attributed to various groups of microorganisms by keeping R1 (1.15) and R2 (0.19) values by using Eqs.4and5. Overall, the proposed nitrogen mass balance shows a clear coupling of ...
In summary, while the ocean’s fixed N input–output budget affects the NO3−δ15N of both the pycnocline and the deep ocean, it has remarkably little effect on the pycnocline–deep ocean NO3−δ15N difference. Nutrient sources to the pycnocline The central goal of this study is to ...
In summary, the snRNA-seq approach identified ongoing CFC-induced cell-specific (mainly neuron-specific) gene expression responses and discrete phenotypic changes 96 h after CFC. Tlr9-KO blunted the induction of most of the up-regulated genes without affecting CFC down-regulated genes and induced...
In summary, based on isotopic observations from a resampling field investigation and simulations from a process-based biogeochemical model, this study explored ecosystem N dynamics across the Tibetan alpine permafrost region. We found an enhanced vegetation N limitation across the study area over the la...
aSummary of the inferred GRN. Network topology parameters are shown. Diam., diameters; Coef., clustering coefficient; *, only regulatory TFs were counted.bRepresentative key regulators identified by network topology analysis (TFs with top out-degree and betweenness centrality are displayed); the expr...
