Data from: Halloysite nanotube-based electrospun ceramic nanofibre mat: a novel support for zeolite membranes

Zhuwen Chen, Jiaying Zeng, Dong Lv, Jinqiang Gao, Jian Zhang, Shan Bai, Ruili Li, Mei Hong & Jingshen Wu
Some key parameters of supports such as porosity, pore shape and size are of great importance for fabrication and performance of zeolite membranes. In this study, we fabricated millimetre-thick, self-standing electrospun ceramic nanofibre mats and employed them as a novel support for zeolite membranes. The nanofibre mats were prepared by electrospinning a halloysite nanotubes/polyvinyl pyrrolidone composite followed by a programmed sintering process. The interwoven nanofibre mats possess up to 80% porosity, narrow pore size distribution,...

The snow leopard, Panthera uncia, is an elusive high-altitude specialist that inhabits vast, inaccessible habitat across Asia. We conducted the first range-wide genetic assessment of snow leopards based on noninvasive scat surveys. Thirty-three microsatellites were genotyped and a total of 683-bp of mitochondrial DNA sequenced in 70 individuals. Snow leopards exhibited low genetic diversity at microsatellites (AN = 5.8, HO = 0.433, HE = 0.568), virtually no mtDNA variation, and underwent a bottleneck in the...

Data from: A new moth-preying alpine pitviper species from Qinghai-Tibetan plateau (Viperidae, Crotalinae)

Jingsong Shi, Gang Wang, Xi'er Chen, Li Ding, Song Huang, Mian Hou, Jun Liu, Pipeng Li, Xi’er Chen & Yihao Fang
The Sanjiangyuan region of Qinghai-Tibetan Plateau is recognized as a biodiversity hotspot of alpine mammals but a barren area in terms of amphibians and reptiles. Here, we describe a new pit viper species, Gloydius rubromaculatus sp. n. Shi, Li and Liu, 2017 that was discovered in this region, with a brief taxonomic revision of the genus Gloydius. The new species can be distinguished from the other congeneric species by the following characteristics: cardinal crossbands on...

Data from: Synchrotron X-ray tomographic microscopy of fossil embryos

Philip C. J. Donoghue, Stefan Bengtson, Xi-Ping Dong, Neil J. Gostling, Therese Huldtgren, John A. Cunningham, Chongyu Yin, Zhao Yue, Fan Peng & Marco Stampanoni
Fossilized embryos from the late Neoproterozoic and earliest Phanerozoic have caused much excitement because they preserve the earliest stages of embryology of animals that represent the initial diversification of metazoans. However, the potential of this material has not been fully realized because of reliance on traditional, non-destructive methods that allow analysis of exposed surfaces only, and destructive methods that preserve only a single two-dimensional view of the interior of the specimen. Here, we have applied...

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....

Detritus decorations as the extended phenotype deflect avian predator attack increasing fitness in an orb‐web spider

Nina Ma, Long Yu, Deyong Gong, Zeyuan Hua, Hua Zeng, Luyao Chen, Aijia Mao, Zhizhao Chen, Ruxing Cai, Yubing Ma, Zengtao Zhang, DQ Li, Jing Luo & Shichang Zhang
A number of strategies that divert attacks of visually guided predators, such as birds, have evolved multiple times in animals. Detritus web decorations built by certain orb-web spider species are thought to deflect avian predator attacks away from spiders and towards their web decorations. Still, empirical evidence for this function and its adaptive significance is lacking. The orb-web spider, Cyclosa monticola, adorns its web using a linear detritus decoration consisting of moults, egg sacs, prey...

Conservation status of a plant family with high endemism, the Primulaceae, in China

Yun-Hao Bai, Si-Yi Zhang, Yanpei Guo & Zhiyao Tang
Primroses, ca 1000 species from the family Primulaceae, are mostly distributed in high mountains and attract people's attention with their high ornamental value. However, they are increasingly threatened by human activities and climate change in recent decades. China harbors more than half of global primrose species, most of which are endemic. To strengthen studies on their conservation, we established a distribution database for primroses in China, including 12 genera and 535 speceies. Based on this...

Data from: Phylogenetic niche conservatism and variations in species diversity-climate relationships

Qinggang Wang, Yaoqi Li, Dongting Zou, Xiangyan Su, Hongyu Cai, Ao Luo, Ke Jiang, Xiaoling Zhang, Xiaoting Xu, Nawal Shrestha & Zhiheng Wang
Although contemporary climate has been identified as one of the major determinants of large-scale species diversity patterns, its effect on species diversity greatly varies among clades. Understanding the drivers of the variation in species diversity-climate relationships (DCRs) across clades, which is critical for developing general mechanisms underlying the effects of climate on species diversity patterns, remains a current challenge. Using newly compiled distribution data of 914 Rosaceae species in China and a dated genus-level phylogeny,...

Data from: Drivers of foliar 15N trends in southern China over the last century

Songbo Tang, Jianfeng Liu, Frank S. Gilliam, Peter Hietz, Zhiheng Wang, Xiankai Lu, Feiyan Zeng, Dazhi Wen, Enqing Hou, Yuan Lai, Yunting Fang, Ying Tu, Dan Xi, Zhiqun Huang, Dianxiang Zhang, Rong Wang & Yuanwen Kuang
Foliar stable nitrogen (N) isotopes (δ15N) generally reflect N availability to plants and have been used to infer about changes thereof. However, previous studies of temporal trends in foliar δ15N have ignored the influence of confounding factors, leading to uncertainties on its indication to N availability. In this study, we measured foliar δ15N of 1,811 herbarium specimens from 12 plant species collected in southern China forests from 1920 to 2010. We explored how changes in...

Considering inner and outer bark as distinctive tissues helps to disentangle the effects of bark traits on decomposition

Li Lin, Li Lin, Yao-Bin Song, Yikang Li, Leo Goudzwaard, Richard S.P. Van Logtestijn, Chenhui Chang, Rob Broekman, Jurgen Van Hal, Juan Zuo, Frank J. Sterck, Lourens Poorter, Ute Sass-Klaassen, Mariet M. Hefting & J. Hans C. Cornelissen
Revealing the ecological consequences of bark multifunctionality and its underlying traits has become a relatively new but essential focus in plant ecology. Although the enormous differences between the most crucial bark layers, i.e., inner and outer bark, in structure and functions have been widely recognized, the overall bark has been regarded as a homogenous tissue in most bark-related studies. This has led to poor knowledge on the functional independence, specialized contributions and possible linkages of...

This dataset contains data of all figures in a submitted manuscript titled "Refining higher modes of Rayleigh waves using seismoelectric signals excited by a weight-drop source: study from numerical simulation aspect " to Journal of Geophysical Research: Solid Earth. Effective extraction of higher mode dispersion information has been a research hotspot in the study of surface waves. In this study, we introduce a novel approach of refining Rayleigh wave higher modes by using seismoelectric signals,...

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: 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...

Long-term empirical evidence, early warning signals, and multiple drivers of regime shifts in a lake ecosystem

Haojie Su, Rong Wang, Yuhao Feng, Yanling Li, Yun Li, Jun Chen, Chi Xu, Shaopeng Wang, Jingyun Fang & Ping Xie
1. Catastrophic regime shifts in various ecosystems are increasing with the intensification of anthropogenic pressures. Understanding and predicting critical transitions are thus a key challenge in ecology. Previous studies have mainly focused on single environmental drivers (e.g., eutrophication) and early warning signals (EWSs) prior to population collapse. However, how multiple environmental stressors interact to shape ecological behaviour and whether EWSs were detectable prior to the recovery process in lake ecosystems are largely unknown. 2. We...

Atmospheric boundary layer intensive sounding data at Cangzhou site

Xipeng Jin, Xuhui Cai & Hongsheng Zhang
This dataset is obtained from a field experiment of intensive GPS (Global Positioning System) boundary layer sounding carried out in Cangzhou (38.3°N, 116.84°E), from 26 November to 26 December 2019. Eight soundings were taken in each day, at 02:00, 05:00, 08:00, 11:00, 14:00, 17:00, 20:00 and 23:00 BJT (i.e., UTC + 8). GPS radiosonde (Beijing Changzhi Sci & Tech Co. Ltd., China) was used to obtain profiles of wind, temperature, humidity and PM2.5 mass concentration...

Grazing-induced biodiversity loss impairs grassland ecosystem stability at multiple scales

Maowei Liang, Cunzhu Liang, Yann Hautier, Kevin Wilcox & Shaopeng Wang
Livestock grazing is a major driver shaping grassland biodiversity, functioning, and stability. Whether grazing impacts on grassland ecosystems are scale-dependent remains unclear. Here, we conducted a sheep-grazing experiment in a temperate grassland to test grazing effects on the temporal stability of productivity across scales. We found that grazing increased species stability, but substantially decreased local community stability due to reduced asynchronous dynamics among species within communities. The negative effect of grazing on local community stability...

Data from: Impacts of species richness on productivity in a large-scale subtropical forest experiment

Yuanyuan 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...

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: Effects of rogue ryanodine receptors on Ca2+ sparks in cardiac myocytes

Xudong Chen, Yundi Feng, Yunlong Huo & Wenchang Tan
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: Developmental biology of the early Cambrian cnidarian Olivooides

Xi-Ping Dong, Kelly Vargas, John A. Cunningham, Huaqiao Zhang, Teng Liu, Fang Chen, Jianbo Liu, Stefan Bengtson & Philip C. J. Donoghue
Fossilized embryos afford direct insight into the pattern of development in extinct organisms, providing unique tests of hypotheses of developmental evolution based in comparative embryology. However, these fossils can only be effective in this role if their embryology and phylogenetic affinities are well constrained. We elucidate and interpret the development of Olivooides from embryonic and adult stages and use these data to discriminate among competing interpretations of their anatomy and affinity. The embryology of Olivooides...

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...

Universal temperature sensitivity of denitrification nitrogen losses in forest soils

Haoming Yu, Yihang Duan, Jan Mulder, Peter Dörsch, Ronghua Kang, Kai Huang, Dongwei Liu, Chao Wang, Zhoutao Zheng, Zhi Quan, Feifei Zhu, Shushi Peng, Weixing Zhu, Yangjian Zhang & Yunting Fang
Soil nitrous oxide (N2O) and nitrogen gas (N2) produced from denitrification are crucial components of the global nitrogen cycle and contribute to nitrogen limitation in terrestrial ecosystems. However, the temperature sensitivity of these gaseous N losses and their underlying processes in forest soils are poorly constrained, limiting our ability to predict nitrogen cycling responses to global warming. Here, we quantify temperature sensitivities (expressed as Q10) of denitrification N2O and N2 production in 18 forest soils...

Data from: Baculovirus infection triggers a positive phototactic response in caterpillars (a response to Dobson et al. Biol Letters 2015).

Stineke Van Houte, Monique M. Van Oers, Yue Han, Just M. Vlak & Vera I. D. Ros
We recently reported that baculovirus Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV) triggers positive phototaxis in Spodoptera exigua larvae, leading to death at elevated positions. Dobson et al. [1] (University of Stirling, Scotland) question our interpretation of the data. Unfortunately, Dobson et al. rely on unwarranted assumptions possibly reflecting a poor understanding of baculovirus–insect pathobiology, make invalid comparisons and fail to take relevant literature into account. Here, we recapitulate the context and interpretation of our experiments and...

Data from: Grazing-induced shifts in community functional composition and soil nutrient availability in Tibetan alpine meadows

Kechang Niu, Jin-Sheng He & Martin J. Lechowicz
The functional structure of plant communities can be altered by grazing through two main mechanisms: species turnover (i.e. changes in species occurrence and relative abundance) and intraspecific trait variability (ITV), which is driven by phenotypic responses of individual plants and shifts in the relative abundance of genotypic variants within species. Studies of grassland ecosystem function under grazing often focus on community changes induced by species turnover, which ignores the effects of ITV on biomass productivity,...

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...
