Data from: Long-term antagonistic effect of increased precipitation and nitrogen addition on soil respiration in a semiarid steppe

Hongyan Han, Yue Du, Dafeng Hui, Lin Jiang, Mingxing Zhong & Shiqiang Wan
Changes in water and nitrogen (N) availability due to climate change and atmospheric N deposition could have significant effects on soil respiration, a major pathway of carbon (C) loss from terrestrial ecosystems. A manipulative experiment simulating increased precipitation and atmospheric N deposition has been conducted for 9 years (2005–2013) in a semiarid grassland in Mongolian Plateau, China. Increased precipitation and N addition interactively affect soil respiration through the 9 years. The interactions demonstrated that N...

Gnetophytes are an enigmatic gymnosperm lineage comprising three genera, Gnetum, Welwitschia and Ephedra, which are morphologically distinct from all other seed plants. Their distinctiveness has triggered much debate as to their origin, evolution and phylogenetic placement among seed plants. To increase our understanding of the evolution of gnetophytes, and their relation to other seed plants, we report here a high-quality draft genome sequence for Gnetum montanum, the first for any gnetophyte. By using a novel...

Data from: Exacerbated nitrogen limitation ends transient stimulation of grassland productivity by increased precipitation

Haiyan Ren, Zhuwen Xu, Forest Isbell, Jianhui Huang, Xingguo Han, Shiqiang Wan, Shiping Chen, Ruzhen Wang, De-Hui Zeng, Yong Jiang & Yunting Fang
Given that plant growth is often water-limited in grasslands, it has been proposed that projected increases in precipitation could increase plant productivity and carbon sequestration. However, the existing evidence for this hypothesis comes primarily from observational studies along natural precipitation gradients or from short-term manipulative experiments. It remains unclear whether long-term increased precipitation persistently stimulates grassland productivity. In the world's largest remaining temperate grassland, we found that experimentally increased precipitation enhanced net primary production, soil...

Data from: Nitrogen deposition cancels out exotic earthworm effects on plant-feeding nematode communities

Yuanhu Shao, Weixin Zhang, Nico Eisenhauer, Tao Liu, Yanmei Xiong, Chenfei Liang & Shenglei Fu
The activity and spread of exotic earthworms often are spatially correlated with N deposition because both arise from human activities. Exotic earthworms, in turn, can also greatly affect soil abiotic and biotic properties, as well as related ecological processes. Previous studies showed, for example, that earthworms can counteract the detrimental effects of plant-feeding nematodes on plant growth. However, potential interactive effects of N deposition and exotic earthworms on ecosystems are poorly understood. We explored the...

Data from: Nitrogen fertilization, not water addition, alters plant phylogenetic community structure in a semi-arid steppe

Xian Yang, Zhongling Yang, Jiaqi Tan, Guoyong Li, Shiqiang Wan & Lin Jiang
1. Anthropogenic environmental changes, such as nitrogen (N) enrichment and alteration in precipitation regimes, significantly influence ecosystems worldwide. However, we know little about whether and how these changes alter the phylogenetic properties of ecological communities. 2. Based on a seven-year field experiment in the temperate semi-arid steppe of Inner Mongolia, China, we investigated the influence of increased N and precipitation on plant phylogenetic structure and phylogenetic patterns of species colonization and extinction. 3. Our study...
