Data from: Multilocus phylogeny and revised classification for mountain dragons of the genus Japalura s.l. (Reptilia: Agamidae: Draconinae) from Asia

Kai Wang, Jing Che, Simin Lin, V. Deepak, Datta-Roy Aniruddha, Ke Jiang, Jieqiong Jin, Hongman Chen & Cameron D. Siler
Although the genus Japalura s.l. has long been recognized as paraphyletic based on limited genetic sampling, its problematic taxonomy has not been revised, and phylogenetic relationships among the majority of congeners remain unknown. Here we utilize a densely sampled dataset of both multilocus genetic and morphological data to provide the first phylogenetic inference of relationships among Japalura s.l.species. Our results show that Japalura s.l. is paraphyletic, consisting of four major clades that are scattered across...

Data from: Males increase call frequency, not intensity, in response to noise, revealing no Lombard effect in the little torrent frog

Longhui Zhao, Xiaoqian Sun, Qinghua Chen, Yue Yang, Jichao Wang, Jianghong Ran, Steven E. Brauth, Yezhong Tang & Jianguo Cui
Noise is one of the main factors that can influence the processes of sound communication across a wide range of animal groups. Although the effects of ambient noise on animal communication, including anthropogenic noise, have received increasing attention, few studies have examined changes in the fine structure of acoustic signals produced by vocalizing species in constantly noisy environments. Here, we used natural recordings to determine the associations between stream noise and call parameters in the...

Data from: Enrichment of lithum from salt lake brine by forward osmosis

Jinli Li, Min Wang, Youjing Zhao, Hongjun Yang & Yuan Zhong
Forward osmosis(FO) is a concentration on the nature phenomena of osmosis. It is nowadays considered a breakthrough technology that can be potentially used for concentrating solutions and suspensions. The diluted nature of brine restricts the treatment technologies that can be applied. Then, brine concentration by FO could represent a habilitating technology enabling the application of a wider range of treatment alternatives. The performance of concentrated brine depended upon FO membranes was investigated at normal temperature...

Data from: Biodiversity explain maximum variation in productivity under experimental warming, nitrogen addition and grazing in mountain grasslands

Jiajia Liu, Detuan Liu, Kun Xu, Lian-Ming Gao, Xuejun Ge, Kevin S. Burgess, Marc W. Cadotte & Xue-Jun Ge
Anthropogenic global warming, nitrogen addition and over-grazing alter plant communities and threaten plant biodiversity, potentially impacting community productivity, especially in sensitive mountain grassland ecosystems. However, it still remains unknown whether the relationship between plant biodiversity and community productivity varies across different anthropogenic influences, and especially how changes in multiple biodiversity facets drive these impacts on productivity. Here we measured different facets of biodiversity including functional and phylogenetic richness and evenness in mountain grasslands along an...

Data from: Simple parameterization of aerodynamic roughness lengths and the turbulent heat fluxes at the top of midlatitude August‐one glacier, Qilian Mountains, China

Shuhai Guo, Rensheng Chen, Guohua Liu, Chuntan Han, Yaoxuan Song, Junfeng Liu, Yong Yang, Zhangwen Liu, Xiqiang Wang, Xiaojiao Liu, Lei Wang & Qin Zheng
The fluxes of sensible heat (H) and latent heat (LE), which are generally the important parts of the energy and mass balances over glacier surfaces, are widely quantified by the bulk method. However, due to the difficulty of determining the aerodynamic roughness length z0m in this method, H and LE values may still have large uncertainties with significant inaccuracy. To acquire reliable varying and intrinsic z0m values, new simpler parameterizations for z0m values at different...

Data from: Allocation strategies for nitrogen and phosphorus in forest plants

Jiahui Zhang, Nianpeng He, Congcong Liu, Li Xu, Qiang Yu & GuiRui Yu
The allocation of limiting elements, such as nitrogen (N) and phosphorus (P), in plants is an important basis for structural stability and functional optimization in natural plant communities. However, because of the lack of systematic investigation data, the mechanisms of optimal nutrient allocation in plants in natural forests are still unclear. Using consistent measurements of N and P contents in 930 plant species, we explored the allocation strategies for N and P in different plant...

Data from: Responses of growing‐season soil respiration to water and nitrogen addition as affected by grazing intensity

Jianjun Li, Yin Huang, Fengwei Xu, Liji Wu, Dima Chen & Yongfei Bai
1. Most grasslands in the world, including the semi-arid steppe in China, are threatened by nitrogen deposition, precipitation change, and livestock grazing, which greatly affect soil carbon processes (e. g., soil respiration). Although the individual effects of nitrogen deposition and precipitation change on soil respiration are well understood, how their effects on soil respiration are altered by different grazing intensities is unclear. 2. To determine how the effects of nitrogen deposition and precipitation change on...

Data from: Negative effects of litter richness on root decomposition in the presence of detritivores

Yinong Li, Xi Chen, Ciska GF Veen, Nico Eisenhauer, Yu Liang, Xiaomei Zhou, Naili Zhang, Keping Ma & G. F. Ciska Veen
1. Decomposition is a vital process underlying many ecosystem functions. Although a growing number of studies have tested how litter richness affects the decomposition of aboveground plant organs, knowledge remains limited about the decomposition of root mixtures. Here, we used a field experiment in a subtropical forest to investigate how species richness in root litter mixtures (air-dried fresh fine roots) affects the decomposition of root litter material. 2. Based on the concept of resource complementarity,...

Data from: Risk of cache pilferage determines hoarding behavior of rodents and seed fate

Lin Cao, Bo Wang, Chuan Yan, Zhenyu Wang, Hongmao Zhang, Yuanzhao Geng, Jin Chen & Zhibin Zhang
Cache pilferage by competitors is thought to drive the evolution of hoarding behavior in animals, which plays significant roles in tree regeneration and formation of mutualisms between trees and animals. However, little is known how cache pilferage risk among seeds of different tree species or years affects hoarding behavior and seed dispersal by animals. We hypothesized that scatter-hoarding rodents could adjust hoarding behavior according to variation in cache pilferage risk among seeds and years to...

Data from: Plant nitrogen and phosphorus utilization under invasive pressure in a montane ecosystem of tropical China

Chaochen Hu, Yanbao Lei, Yunhong Tan, Xinchao Sun, Hao Xu, Congqiang Liu & Xueyan Liu
1. Exotic plant invasion has been changing the vegetation composition and function of terrestrial ecosystems. Nitrogen (N) and phosphorus (P) are often the limiting nutrients for terrestrial plants. However, under invasive pressure, in-situ plant N and P use mechanisms remain poorly understood but is pivotal for a better understanding of plant invasion and coexistence in invaded ecosystems. 2. Nitrogen and P concentrations, natural 15N abundance (δ15N values) were investigated in leaves and soils under different...

Data from: Phylogenomics resolves the deep phylogeny of seed plants and indicates partial convergent or homoplastic evolution between Gnetales and angiosperms

Jin-Hua Ran, Ting-Ting Shen, Ming-Ming Wang & Xiao-Quan Wang
After decades of molecular phylogenetic studies, the deep phylogeny of gymnosperms has not been resolved, and the phylogenetic placement of Gnetales remains one of the most controversial issues in seed plant evolution. To resolve the deep phylogeny of seed plants and to address the sources of phylogenetic conflict, we conducted a phylotranscriptomic study with a sampling of all 13 families of gymnosperms and main lineages of angiosperms. Multiple datasets containing up to 1 296 042...

Data from: Landscape genomics provides evidence of climate-associated genetic variation in Mexican populations of Quercus rugosa Nee

Karina Martins, Paul Gugger, Jesus Llanderal-Mendoza, Antonio González-Rodríguez, Sorel T. Fitz-Gibbon, Jian-Li Zhao, Hernando Rodríguez-Correa, Ken Oyama, Victoria L. Sork & Paul F. Gugger
Local adaptation is a critical evolutionary process that allows plants to grow better in their local compared to nonnative habitat and results in species-wide geographic patterns of adaptive genetic variation. For forest tree species with a long generation time, this spatial genetic heterogeneity can shape the ability of trees to respond to rapid climate change. Here, we identify genomic variation that may confer local environmental adaptations and then predict the extent of adaptive mismatch under...

Data from: Stream diatoms exhibit weak niche conservation along global environmental and climatic gradients

Janne Soininen, Aurelien Jamoneau, Juliette Tison-Rosebery, Thibault Leboucher, Jianjun Wang, Mikolaj Kokocinski & Sophia I. Passy
Niche conservatism (NC) describes the scenario in which species retain similar characteristics or traits over time and space, and thus has potentially important implications for understanding their biogeographic distributions. Evidence consistent with NC includes similar niche properties across geographically distant regions. We investigated whether NC was evident in stream diatom morphospecies by modeling species responses to environmental and climatic variables in a set of calibration sites (from the US) and then evaluated the models with...

Data from: The cover uncovered: bark control over wood decomposition

Gbadamassi G.O. Dossa, Douglas Schaefer, Jiao-Lin Zhang, Jian-Ping Tao, Kun-Fang Cao, Richard T. Corlett, Anthony B. Cunningham, Jian-Chu Xu, Johannes H. C. Cornelissen, Rhett D. Harrison & Gbadamassi G. O. Dossa
1. Woody debris (WD) represents a globally significant carbon stock and its decomposition returns nutrients to the soil while providing habitat to microbes, plants and animals. Understanding what drives WD decomposition is therefore important. 2. WD decomposition rates differ greatly among species. However, the role of bark in the process remains poorly known. 3. We ask how, and how much, interspecific variation in bark functional traits related to growth and protection have afterlife effects on...

Data from: Cytochrome P450 and O-methyltransferase catalyze the final steps in the biosynthesis of the anti-addictive alkaloid ibogaine from Tabernanthe iboga

Scott C. Farrow, Mohamed O. Kamileen, Jessica Meades, Belinda Ameyaw, Youli Xiao & Sarah E. O'Connor
Monoterpenoid indole alkaloids (MIAs) are a large (ca. 3000 members) and structurally diverse class of metabolites restricted to a limited number of plant families in the order Gentianales. Tabernanthe iboga or iboga (Apocynaceae) is native to western equatorial Africa and has been used in traditional medicine for centuries. Howard Lotsof is credited with bringing iboga to the attention of Western medicine through his accidental discovery that iboga can alleviate opioid withdrawal symptoms. Since this observation,...

Data from: Redescription of Phymolepis cuifengshanensis (Antiarcha: Yunnanolepididae) using high-resolution computed tomography and new insights into anatomical details of the endocranium in antiarchs

Yajing Wang & Min Zhu
Background. Yunnanolepidoids constitute either the basal-most consecutive segments or the most primitive clade of antiarchs, a highly diversified jawed vertebrate group from the Silurian and Early Devonian periods. Although the general morphology of yunnanolepidoids is well established, their endocranial features remain largely unclear, thus hindering our further understanding of antiarch evolution, and early gnathostome evolution. Phymolepis cuifengshanensis, a yunnanolepidoid from the Early Devonian of southwestern China, is re-described in detail to reveal the information on...

Data from: Past distribution of epiphyllous liverworts in China: the usability of historical data

Yanbin Jiang, Tiejun Wang, Yupeng Wu, Ronggui Hu, Ke Huang & Xiaoming Shao
Epiphyllous liverworts form a special group of bryophytes that primarily grow on the leaves of understory vascular plants in tropical and subtropical evergreen broadleaf forests. Being sensitive to moisture and temperature changes, epiphyllous liverworts are often consider to be good indicators of climate change and forest degradation. However, they are a poorly collected and taxonomically complicated group, with an only partly identified distribution pattern. In this study, we built four models based on 24 environmental...

Data from: Comparison of methods for molecular species delimitation across a range of speciation scenarios

Arong Luo, Cheng Ling, Simon Y.W. Ho, Chao-Dong Zhu & Simon Y W Ho
Species are fundamental units in biological research and can be defined on the basis of various operational criteria. There has been growing use of molecular approaches for species delimitation. Among the most widely used methods, the generalized mixed Yule-coalescent (GMYC) and Poisson tree processes (PTP) were designed for the analysis of single-locus data but are often applied to concatenations of multilocus data. In contrast, the Bayesian multispecies coalescent approach in the software BPP explicitly models...

Data from: Cytotaxonomy of Piptatherum kuoi (Stipeae, Poaceae)

Zhong-Shuai Zhang & Wen-Li Chen
The generic placement of Piptatherum kuoi (Poaceae, Stipeae) has long been a controversial matter. Recent molecular phylogenetic analyses indicate that Piptatherum kuoi should be transferred to Patis. Here, we present cytological evidence for this transfer. Piptatherum kuoi has a chromosome number of 2n = 46 with the chromosomes varying in length between 1.1 – 3.1 μm, and a symmetrical karyotype 2n = 26m + 16sm + 4st (2sat). Karyological characters of Piptatherum kuoi, including chromosome...

Data from: Evolution of angiosperm pollen. 6. the Celastrales, Oxalidales, and Malpighiales (COM) clade and Zygophyllales

Zhi-Bin Tao, Alexandra H. Wortley, Lu Lu, De-Zhu Li, Hong Wang & Stephen Blackmore
Analyzing pollen morphological data on a contemporary phylogenetic framework can enhance our understanding of the distribution, diversity, and evolution of palynological characters. In this paper, the sixth in a series detailing pollen morphological characters across angiosperms, we focus on the Celastrales, Oxalidales, and Malpighiales (COM) clade and Zygophyllales, together comprising ca. 20,000 species in 47 families within fabids. We first examined pollen grains from 21 species with light, scanning electron, and transmission electron microscopy, to...

Data from: Individual-level trait variation and negative density dependence affects growth in tropical tree seedlings

Maria Natalia Umana, Elise F. Zipkin, Caicai Zhang, Min Cao, Luxiang Lin & Nathan G. Swenson
1. Individual-level interactions with neighbours and their surrounding environments are key factors influencing performance that ultimately shape and maintain diversity in tropical plant communities. Theory predicts that the strength of these interactions depends on the similarity among neighbours, the turnover in composition caused by individuals that enter as new recruits and individuals that die, and fitting to local conditions. Despite considerable phenotypic variation among individuals and high community dynamics, these three factors have rarely been...

Data from: Facile fabrication of microfluidic surface-enhanced raman scattering devices via lift-up lithography

Yuanzi Wu, Ye Jiang, Xiaoshan Zheng, Shasha Jia, Zhi Zhu, Bin Ren & Hongwei Ma
We describe a facile and low-cost approach for flexible integration surface-enhanced Raman scattering (SERS) substrate in microfluidic chips. Briefly, a SERS substrate was fabricated by electrostatic assembly of gold nanoparticles, and shaped into designed patterns by the subsequent lift-up soft lithography. The SERS micropattern could be further integrated within microfluidic channels conveniently. The resulting microfluidic SERS chip allows one to ultrasensitively in-situ SERS monitor from the transparent glass window. With its advantages in simplicity, functionality,...

Data from: Rainfall pulse response of carbon fluxes in a temperate grass ecosystem in the semiarid Loess Plateau

Yakun Tang, Jun Jiang, Chen Chen, Yunming Chen & Xu Wu
Rainfall pulses can significantly influence carbon cycling in water limited ecosystems. The magnitude of carbon flux component responses to precipitation may vary depending on precipitation amount and antecedent soil moisture, associated with nonlinear responses of plants and soil microbes. The present study was carried out in a temperate grass ecosystem during 2013–2015 in the semiarid Loess Plateau of China, to examine the response of carbon fluxes to precipitation using the “threshold-delay” model. The unique contribution...

Data from: Vegetation type controls root turnover in global grasslands

Jinsong Wang, Jian Sun, Zhen Yu, Yong Li, Dashuan Tian, Bingxue Wang, Zhaolei Li & Shuli Niu
Abstract: Aim: Root turnover is an important process determining carbon and nutrient cycling in terrestrial ecosystems. It is an established fact that root turnover is jointly regulated by climatic, edaphic, and biotic factors. However, the relative importance of these forces in determining the global patterns of root turnover time is far from clear. Location: Global. Time period: 1946–2017. Major taxa studied: Grasslands. Methods: We compiled a database of 141 sites with 433 observations on root...

Data from: Plant functional groups regulate soil respiration responses to nitrogen addition and mowing over a decade

Yue Du, Hongyan Han, Yanfen Wang, Mingxing Zhong, Dafeng Hui, Shuli Niu & Shiqiang Wan
1. Nitrogen (N) deposition and land-use practice (e.g. mowing) could have profound effects on soil respiration. However, the changes in other ecosystem components, such as plant functional groups (PFGs), may control soil carbon (C) efflux response to long term global change. 2. A 10-year (2005-2014) field experiment was conducted with both N addition (10g N m-2 yr-1) and mowing (once a year) in a northern Chinese temperate grassland. We collected continuous data on soil respiration...
