Data from: Impacts of species richness on productivity in a large-scale subtropical forest experimentYuanyuan Huang, Yuxin Chen, Nadia Castro-Izaguirre, Martin Baruffol, Matteo Brezzi, Anne Lang, Ying Li, Werner Härdtle, Werner Von Oheimb, Xuefeu Yang, Xiaojuan Liu, Kequan Pei, Sabine Both, Bo Yang, David Eichenberg, Thorsten Assmann, Jürgen Bauhus, Thorsten Behrens, François Buscot, Xiao-Yong Chen, Douglas Chester, Bing-Yang Ding, Walter Durka, Alexandra Erfmeier, Jingyun Fang … & Bernhard Schmid
Biodiversity experiments have shown that species loss reduces ecosystem functioning in grassland. To test whether this result can be extrapolated to forests, the main contributors to terrestrial primary productivity, requires large-scale experiments. We manipulated tree species richness by planting more than 150,000 trees in plots with 1 to 16 species. Simulating multiple extinction scenarios, we found that richness strongly increased stand-level productivity. After 8 years, 16-species mixtures had accumulated over twice the amount of carbon...
Ca2+ sparks and Ca2+ quarks, arising from clustered and rogue ryanodine receptors (RyRs), are significant Ca2+ release events from the junctional sarcoplasmic reticulum (JSR). Based on the anomalous subdiffusion of Ca2+ in the cytoplasm, a mathematical model was developed to investigate the effects of rogue RyRs on Ca2+ sparks in cardiac myocytes. Ca2+ quarks and sparks from the stochastic opening of rogue and clustered RyRs are numerically reproduced and agree with experimental measurements. It is...
Data from: Prognostic value of ki67 in BCG-treated non-muscle invasive bladder cancer: a meta-analysis and systematic reviewYuhui He, Ning Wang, Xiaofeng Zhou, Jianfeng Wang, Zhenshan Ding, Xing Chen & Yisen Deng
Objectives: The aim of this study was to explore the prognostic value of ki67 as a marker in non-muscle-invasive bladder cancer (NMIBC) patients treated with Bacillus Calmette–Guérin (BCG). Methods: Studies were systematically retrieved from the relevant databases (Web of Science, PubMed, Cochrane Library, and Embase), and the expiry date was May 2017. The research steps referred to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement. Results: A total of 11 studies that complied...
Forest ecosystems are an integral component of the global carbon cycle as they take up and release large amounts of C in short time (C flux) or accumulate it over longer time (C stock). However, there remains uncertainty about whether and in which direction C fluxes and in particular C stocks may differ between forests of high vs. low species richness. Based on a comprehensive dataset derived from field-based measurements, we tested the effect of...
Global warming exerts profound impacts on terrestrial carbon cycles and feedback to climates. Ecosystem respiration (ER) is one of the main components of biosphere CO2 fluxes. However, knowledge regarding how ER responds to warming is still lacking. In this study, a manipulative experiment with five simulated temperature increases (Control, Warming 1, Warming 2, Warming 3, Warming 4) was conducted to investigate ER responses to warming in an alpine meadow on the Tibetan Plateau. The results...
Data from: Dryland soils in northern China sequester carbon during the early-2000s warming hiatus periodDan Kou, Wenhong Ma, Jinzhi Ding, Beibei Zhang, Kai Fang, Huifeng Hu, Jianchun Yu, Tian Wang, Shuqi Qin, Xia Zhao, Jingyun Fang & Yuanhe Yang
1. Drylands, covering ~45% of the Earth’s terrestrial surface and supporting ~38% of the global population, play a dominant role in the trend and inter-annual variability of global land carbon (C) sink. Given that a large proportion of organic C is stored in soils, our knowledge on soil C dynamics in drylands is crucial to evaluate terrestrial C-climate feedback. However, credible understanding on this issue is still greatly limited by the lack of direct observations....
Data from: Nutrient addition affects scaling relationship of leaf nitrogen to phosphorus in Arabidopsis thalianaZhengbing Yan, Xiuping Li, Di Tian, Wenxuan Han, Xinghui Hou, Haihua Shen, Yalong Guo & Jingyun Fang
1. Ambient nutrient changes influence the coupling of nitrogen (N) and phosphorus (P) in terrestrial ecosystems, but whether it could alter the scaling relationship of plant leaf N to P concentrations remains unclear. 2. Here we conducted experimental manipulations using Arabidopsis thaliana, with five levels of N and P additions and nine repeated experiments, and then evaluated the changes in the scaling relationship of leaf N to P concentrations under nutrient additions. 3. Overall, leaf...
Data from: Convenient fabrication of conjugated polymer semiconductor nanotubes and their application in organic electronicsLanchao Ma, Shuixing Dai, Xiaowei Zhan, Xinyang Liu & Yu Li
Organic heterojunction is indispensable in organic electronic devices, such as organic solar cells (OSCs), organic light-emitting diodes (OLEDs) and so on. Fabrication of core-shell nanostructure provides feasible and novel way to prepare organic heterojunction, which is beneficial for miniaturization and integration of organic electronic devices. Fabrication of nanotubes which constitute the core-shell structure in large quantity is the key for the realization of application. In this work, a simple and convenient method to prepare nanotubes...
