Precipitation Determines the Global Nitrogen Cycle in Terrestrial Ecosystems Inferred from Stable Isotopes and Functional Genes.xlsx

Surface soils along elevation transects of the Tibetan Plateau (TP) were sampled to investigate the N-associated biogeochemical indicators, including the stable isotopes (δ15N of organic and inorganic N, and δ18O of nitrate) and functional genes of N-cycling microbes (ammonia-oxidizing bacteria and archaea, nitrate-reducing bacteria, nitrite-reducing bacteria).

为探究氮相关生物地球化学指标，研究人员对青藏高原（Tibetan Plateau, TP）沿海拔样带的表层土壤进行了采样，所涉指标包括稳定同位素（有机氮与无机氮的δ15N、硝酸盐的δ18O）以及氮循环微生物的功能基因（氨氧化细菌与古菌、硝酸盐还原菌、亚硝酸盐还原菌）。
