Data from: Exacerbated grassland degradation and desertification in Central Asia during 2000-2014

Geli Zhang, Chandrashekhar M. Biradar, Xiangming Xiao, Jinwei Dong, Yuting Zhou, Yuanwei Qin, Yao Zhang, Fang Liu, Mingjun Ding & Richard J. Thomas
Grassland degradation and desertification is a complex process, including both state conversion (e.g., grasslands to deserts) and gradual within-state change (e.g., greenness dynamics). Existing studies hardly separated the two components and analyzed it as a whole based on time series vegetation index data, which however cannot provide a clear and comprehensive picture for grassland degradation and desertification. Here we proposed an integrated assessment strategy, by considering both state conversion and within-state change of grasslands, to...

Data from: Variation of stomatal traits from cold-temperate to tropical forests and association with water use efficiency

Congcong Liu, Nianpeng He, Jiahui Zhang, Ying Li, Qiufeng Wang, Lawren Sack & Guirui Yu
1.Stomata control carbon and water vapor exchange between leaves and the atmosphere, thus it can influence water use efficiency and reflect plant adaptation to climate. However, the spatial patterns of leaf stomatal traits and relationships between stomatal trait and water use efficiency across natural communities remain unclear. 2.We measured stomatal density, stomatal size, and stomatal area fraction for 737 plant species from nine forests ranging from tropical to cold-temperate forests. 3.Stomatal density, stomatal size, and...

Data from: Variation in leaf anatomical traits from tropical to cold-temperate forests and linkage to ecosystem functions

Nianpeng He, Congcong Liu, Miao Tian, Meiling Li, Hao Yang, Guirui Yu, Dali Guo, Melinda D. Smith, Qiang Yu & Jihua Hou
1. Leaf anatomical traits may reflect plant's adaption to environmental changes and influence ecosystem functions, as they regulate light absorption and gas exchange to some extent. Here, we hypothesized that leaf anatomical traits were closely related to gross primary productivity (GPP) because photosynthesis commonly occurs in the chloroplasts of palisade and spongy tissues in leaf. 2. Eight leaf anatomical traits were measured in 916 plant species inhabiting from tropical to cold-temperate forests in eastern China:...

Data from: Contrasting responses of phosphatase kinetic parameters to nitrogen and phosphorus additions in forest soils

Xinyu Zhang, Yang Yang, Chuang Zhang, Shuli Niu, Guirui Yu, Huimin Wang, Evgenia Blagodatskaya, Yakov Kuzyakov, Dashuan Tian, Yuqian Tang, Shuang Liu & Xiaomin Sun
1. Global changes include increasing nitrogen (N) and phosphorus (P) deposition, which affect microbial nutrient demand and biogeochemical cycles. The responses of P-mineralizing enzymes to these global change components are poorly defined and are not specified in forest soils differing in P content. 2. We chose one site in a P-rich and two sites in P-poor forests and established sixteen 20 × 20 m plots at each site. Control, either N only, P only, or...

Data from: Different phylogenetic and environmental controls of first-order root morphological and nutrient traits: evidence of multidimensional root traits

Ruili Wang, Qiufeng Wang, Ning Zhao, Zhiwei Xu, Xianjin Zhu, Cui Jiao, Guirui Yu, Nianpeng He & Cuicui Jiao
1. Although fine roots are essential for the water and nutrient uptake of plants, there is limited understanding of root trait variation and the underlying mechanism. 2. Here, six first-order root morphological and chemical traits were measured for 181 species from eight subtropical and boreal forests to test the hypothesis of different phylogenetic and environmental regulations of root morphological and nutrient traits result in the multidimensions of root traits. 3. Two independent root trait dimensions...

Data from: Scale dependence of the diversity–stability relationship in a temperate grassland

Yunhai Zhang, Nianpeng He, Michel Loreau, Qingmin Pan & Xingguo Han
1. A positive relationship between biodiversity and ecosystem stability has been reported in many ecosystems; however, it has yet to be determined whether and how spatial scale affects this relationship. Here, for the first time, we assessed the effects of alpha, beta and gamma diversity on ecosystem stability and the scale dependence of the slope of the diversity–stability relationship. 2. By employing a long-term (33 years) dataset from a temperate grassland, northern China, we calculated...

Data from: Soil gross N ammonification and nitrification from tropical to temperate forests in eastern China

Changhui Wang, Nannan Wang, Jianxing Zhu, Yuan Liu, Xiaofeng Xu, Shuli Niu, Guirui Yu, Xingguo Han & Nianpeng He
1. Nitrogen (N) ammonification and nitrification are two primary microbial processes controlling the availability of soil ammonium (NH4+), a key nutrient for vegetative growth. The large-scale patterns of gross ammonification (GA) and gross nitrification (GN) rates represent soil microbial adaptations to different vegetative and environmental conditions. In this study, we investigated GA and GN rates in nine forest soils along a 3500-km north-south transect in eastern China (NSTEC). 2. We used 15N-labeling techniques, along with...

Data from: Mowing exacerbates the loss of ecosystem stability under nitrogen enrichment in a temperate grassland

Yunhai Zhang, Michel Loreau, Nianpeng He, Guangming Zhang & Xingguo Han
Summary: 1. Global reactive nitrogen (N) is projected to further increase in the coming years. Previous studies have demonstrated that N enrichment weakens the temporal stability of ecosystem primary productivity through decreased biodiversity and species asynchrony. Mowing is a globally common practice in grasslands; and infrequent mowing can maintain or increase plant diversity under N enrichment conditions. However, it is unclear how infrequent mowing affects ecosystem stability in the face of N enrichment. 2. By...

Data from: Soil drainage facilitates earthworm invasion and subsequent carbon loss from peatland soil

Xinwei Wu, Rui Cao, Xue Wei, Xinqiang Xi, Peili Shi, Nico Eisenhauer & Shucun Sun
1. Human activities have been a significant driver of environmental changes with tremendous consequences for carbon dynamics. Peatlands are critical ecosystems because they store ~30% of the global soil organic carbon pool and are particularly vulnerable to anthropogenic changes. The Zoige peatland on the eastern Tibet Plateau, as the largest alpine peatland in the world, accounts for 1‰ of global peat soil organic carbon storage. However, this peatland has experienced dramatic climate change including increased...

Data from: C:N:P stoichiometry in China's forests: from organs to ecosystems

Jiahui Zhang, Ning Zhao, Congcong Liu, Hao Yang, Meiling Li, Guirui Yu, Kevin Wilcox, Qiang Yu & Nianpeng He
Ecological stoichiometry connects different levels of biology, from the gene to the globe, by scaling up elemental ratios (e.g., carbon [C], nitrogen [N], and phosphorus [P]). Thus, ecological stoichiometry could be a powerful tool for revealing certain physiological processes of plants. However, C:N:P stoichiometry remains unclear at the community and ecosystem level, despite it being potentially important for primary productivity. In this study, we measured the C, N, and P content of different plant organs,...

Data from: Root elemental composition in Chinese forests: implications for biogeochemical niche differentiation

Ning Zhao, Hui Liu, Qiufeng Wang, Ruili Wang, Zhiwei Xu, Cui Jiao, Jianxing Zhu, Guirui Yu, Nianpeng He, Huiming Liu & Cuicui Jiao
1. Trait-based community analysis provides a new approach to integrate functional ecology with community ecology. However, our understanding of the linkages between root chemical traits and community chemical diversity and assembly is still in its infancy. 2. Environmental filtering and niche differentiation are two opposite driving forces of community assembly based on deterministic niche processes. We hypothesize that environmental filtering is a strong driver of root chemical assembly at a large spatial scale, whereas biogeochemical...
