Data from: Unraveling independent origins of two tetraploid Achillea species by amplicon sequencing

Jun-Nan Wan, Yan-Ping Guo & Guang-Yuan Rao
Allopolyploidy is a significant mechanism of plant speciation, and many allopolyploid species have arisen recurrently. However, the probability that allopolyploidization between the same two parental species may lead to the origin of different taxa has received little attention. Here we used a new progenitor-specific amplicon sequencing method to demonstrate the independent origins of two yarrow species, Achillea alpina and A. wilsoniana, via allotetraploidy from the same diploid progenitor species pair, A. acuminata and A. asiatica....

Data from: Progression of cognitive decline before and after incident stroke

Fanfan Zheng, Li Yan, Baoliang Zhong, Zhenchun Yang & Wuxiang Xie
Objective: To determine the trajectory of cognitive decline before and after incident stroke. Methods: By using data from the English Longitudinal Study of Ageing, we studied 9278 nondemented participants with no history of stroke who underwent cognitive assessment at baseline (wave 1), and at least one other timepoint (waves 2 to 7). We used linear mixed models to analyze repeated measures and longitudinal data. Results: Among the 9278 participants (56.8% women, mean age 63.1±10.3 years),...

Data from: Nonlinearity of root trait relationships and the root economics spectrum

Deliang Kong, Junjian Wang, Huifang Wu, Oscar J. Valverde-Barrantes, Ruili Wang, Hui Zeng, Paul Kardol, Haiyan Zhang & Yulong Feng
The root economics spectrum (RES), a common hypothesis postulating a tradeoff between resource acquisition and conservation traits, is being challenged by conflicting relationships between root diameter, tissue density (RTD) and root nitrogen concentration (RN). Here, we analyze a global trait dataset of absorptive roots for over 800 plant species. For woody species (but not for non-woody species), we find nonlinear relationships between root diameter and RTD and RN, which stem from the allometric relationship between...

Data from: Superposed epoch analysis of the energetic electron flux variations during CIRs measured by BD-IES

Zefan Yin, Hong Zou, Yu Guang Ye, Qiu-Gang Zong & Yongfu Wang
The flux variations of energetic electrons is one of the most important topics to understand dynamic processes in the space environment and the forecast for high-energy electron burst. BD-IES, an imaging energetic electron spectrometer onboard a Chinese navigation satellite at an inclined geosynchronous orbit (IGSO), can provide 50-600keV electron flux data, which is used to investigate electron flux variations at GEO orbit during Co-rotating Interactive Region events (CIRs). The superposed epoch analysis is applied to...

Assessment of fish communities using eDNA: effect of spatial sampling design in lentic systems of different sizes

Shan Zhang, Qi Lu, Yiyan Wang, Xiaomei Wang, Jindong Zhao & Meng Yao
Freshwater fish biodiversity is quickly decreasing and requires effective monitoring and conservation. Environmental DNA (eDNA)-based methods have been shown to be highly sensitive and cost-efficient for aquatic biodiversity surveys, but few studies have systematically investigated how spatial sampling design affects eDNA-detected fish communities across lentic systems of different sizes. We compared the spatial patterns of fish diversity determined using eDNA in three lakes of small (SL; 3 ha), medium (ML; 122 ha) and large (LL;...

Data from: Anterior insular cortex plays a critical role in interoceptive attention

Xingchao Wang, Qiong Wu, Laura Egan, Xiaosi Gu, Pinan Liu, Hong Gu, Yihong Yang, Jing Luo, Yanhong Wu, Zhixian Gao & Jin Fan
Accumulating evidence indicates that the anterior insular cortex (AIC) mediates interoceptive attention, which refers to attention towards physiological signals arising from the body. However, the necessity of the AIC in this process has not been demonstrated. Using a novel task that directs attention toward breathing rhythm, we assessed the involvement of the AIC in interoceptive attention in healthy participants using functional magnetic resonance imaging and examined the necessity of the AIC in interoceptive attention in...

Responses of four dominant dryland plant species to climate change in the Junggar Basin, north-west China

Jian Xiao, Anwar Eziz, Heng Zhang, Zhiheng Wang, Zhiyao Tang & Jinyun Fang
Aim Dryland ecosystems are exceedingly sensitive to climate change. Desertification induced by both climate changes and human activities seriously threatens the dryland vegetation. However, the impact of climate change on distributions of dryland plant species has not been well documented. Here, we studied the potential distributions of four representative dryland plant species (Haloxylon ammodendron, Anabasis aphylla, Calligonum mongolicum, and Populus euphratica) under current and future climate scenarios in a temperate desert region, aiming to improve...

Data from: One-shot dilation versus serial dilation technique for access in percutaneous nephrolithotomy: a systematic review and meta-analysis

Panxin Peng, Shicong Lai, Zhenshan Ding, Yuhui He, Lihua Zhou, Xuming Wang & Guan Zhang
Objective: The purpose of this study was to systematically review the outcomes of the use of one-shot dilation (OSD) and serial tract dilation for percutaneous nephrolithotomy (PCNL). Methods: A systematic review and meta-analysis was conducted. The randomized controlled trials (RCTs) included in the study were identified from EMBASE, MEDLINE, and the Cochrane Central Register of Controlled Trials. The last search was performed on April 30, 2018. Summary effects were calculated as risk ratios (RRs) with...

Data from: An alternative approach to reduce algorithm-derived biases in monitoring soil organic carbon changes

Weixin Zhang, Yuanqi Chen, Leilei Shi, Xiaoli Wang, Yongwen Liu, Rong Mao, Xingquan Rao, Yongbiao Lin, Yuanhu Shao, Xiaobo Li, Cancan Zhao, Shengjie Liu, Shilong Piao, Weixing Zhu, Xiaoming Zou & Shenglei Fu
Quantifying soil organic carbon (SOC) changes is a fundamental issue in ecology and sustainable agriculture. However, the algorithm-derived biases in comparing SOC status have not been fully addressed. Although the methods based on equivalent soil mass (ESM) and mineral-matter mass (EMMM) reduced biases of the conventional methods based on equivalent soil volume (ESV), they face challenges in ensuring both data comparability and accuracy of SOC estimation due to unequal basis for comparison and using un-conserved...

Data from: Characterization of cytoplasmic viscosity of hundreds of single tumor cells based on micropipette aspiration

Ke Wang, Xiaohao H. Sun, Yi Zhang, Teng Zhang, Yu Zheng, Yuanchen C. Wei, Peng Zhao, Deyong Y. Chen, Hengan A. Wu, Wenhui H. Wang, Rong Long, Junbo B. Wang & Jian Chen
Background: Cytoplasmic viscosity (μc) is a key biomechanical parameter for evaluating the status of cellular cytoskeletons. Previous studies focused on white blood cells, but the data of cytoplasmic viscosity for tumor cells were missing. Methodology: Tumor cells (H1299, A549 and drug-treated H1299 with compromised cytoskeletons) were aspirated continuously through a micropipette at a pressure of -10 kPa or -5 kPa where aspiration lengths as a function of time were obtained and translated to cytoplasmic viscosity...

Data from: Horizontal and vertical diversity jointly shape food web stability against small and large perturbations

Qinghua Zhao, Paul J. Van Den Brink, Camille Carpentier, Yingying. X. G. Wang, Pablo Rodríguez-Sánchez, Chi Xu, Silke Vollbrecht, Frits Gillissen, Marlies Vollebregt, Shaopeng Wang & Frederik De Laender
The biodiversity of food webs is composed of horizontal (i.e. within trophic levels) and vertical diversity (i.e. the number of trophic levels). Understanding their joint effect on stability is a key challenge. Theory mostly considers their individual effects and focuses on small perturbations near equilibrium in hypothetical food webs. Here, we study the joint effects of horizontal and vertical diversity on the stability of hypothetical (modelled) and empirical food webs. In modelled food webs, horizontal...

Data from: A consistent species richness-climate relationship for oaks across the Northern Hemisphere

Xiaoting Xu, Dimitar Dimitrov, Nawal Shrestha, Carsten Rahbek & Zhiheng Wang
Aim: Although the effects of climate on species richness are known, regional processes may lead to different species richness-climate relationships across continents resulting in species richness anomalies, especially for tropical groups. Phylogenetic niche conservatism may also influence species richness-climate relationships of different lineages. Here, we tested whether regional effects also exist for temperate lineages using the genus Quercus. Location: Northern Hemisphere Time period: Present day Major taxa studied: Quercus (Fagaceae) Methods: We used a dated...
