Assessment of nitrogen (N) saturation of forests is critical to evaluate how ecosystems will respond to current and future global changes such as N deposition. However, quantifying N saturation remains a challenge. We developed a conceptual model of N saturation stages in forest ecosystems based on i) a hypothetical relative rate of ammonification, nitrification, and denitrification, ii) concentrations of ammonium and nitrate in the soil, and iii) 15N enrichment pattern of bulk soil N, ammonium,...

Retention fraction of 15N-labelled deposited ammonium and nitrate in forests

Geshere Abdisa Gurmesa, Ang Wang, Shanlong Li, Shushi Peng, Wim De Vries, Per Gundersen, Philippe Ciais, Oliver L Phillips, Erik Hobbie, Weixing Zhu, Knute Nadelhoffer, Yi Xi, Edith Bai, Tao Sun, Dexiang Chen, Wenjun Zhou, Yiping Zhang, Yingrong Guo, Jiaojun Zhu, Lei Duan, Dejun Li, Keisuke Koba, Enzai Du, Guoyi Zhou, Xingguo Han … & Yunting Fang
The impacts of enhanced nitrogen (N) deposition on 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 reactive N forms and its contribution to forest C sink is unclear. We conducted ecosystem-scale paired 15N-labelling experiments in nine forests across China to quantify N retention...

Species co-occurrence shapes spatial variability in plant diversity–biomass relationships in natural rangelands under different grazing intensities

Anvar Sanaei, Emma J. Sayer, Hugo Saiz, Zuoqiang Yuan & Arshad Ali
Grazing can alter plant species interactions in natural rangelands, which in turn might influence the productivity of the ecosystem but we do not fully understand how spatial variability in plant diversity-biomass relationships are modulated by grazing intensity. Here, we hypothesized that plant species co-occurrence in rangelands is mainly driven by niche segregation due to grazing and heterogeneity in local resources, and that grazing therefore modulates diversity–biomass relationships. We tested our hypothesis across 35 rangeland sites...

Environmental factors, habitats and density of rare and endangered plants

Quanlai Zhou & Yongcui Wang
This dataset contains data from the list of the National Key Protected Wild Plants (the first and second batches) officially approved by the State Council, 1898 plants were recorded in the information system of the Chinese Rare and Endangered Plants. The dataset includes: name of species (Latin Name), Place (counties in China), Latitude and Longitude (coordinates of the Place), MAP (Mean annual precipitation), MAT (Mean annual temperature) and MAH (Mean annual humidity), Altitude (Vertical distribution...

Large-scale homogenization of soil bacterial communities in response to agricultural practices in paddy fields, China

Hang Wang, Sheng-En Liu, Zhi-Jian Zhang, Hao-Cai Wang, Xing-Hua Tao, Xian-Zhe Wang, Hong-Yi Li & Chen-Li Wang
This dataset contains data from 257 sites in four typical rice-growing regions across a 4,000-km transect in China, including geographic location data and environment factors data. The study was conducted across a 4,000-km transect of China’s rice-growing areas, from Heilong Jiang province to Yunnan province (100°55′ E to 134°08′° E, 22°46′ N to 48°02′ N, Table S1). Four typical rice-growing regions were selected along this transect: Sanjiang Plain (modern mechanical farming), Taihu Plain (mechanical plus...
