Data from: Multilocus analysis of nucleotide variation and speciation in three closely related Populus (Salicaceae) species

Shuhui Du, Zhaoshan Wang, Pär K. Ingvarsson, Junhui Wang, Zhiqiang Wu, Luke R. Tembrock & Jianguo Zhang
Historical tectonism and climate oscillations can isolate and contract the geographical distributions of many plant species, and they are even known to trigger species divergence and ultimately speciation. Here, we estimated the nucleotide variation and speciation in three closely related Populus species, Populus tremuloides, P. tremula and P. davidiana, distributed in North America and Eurasia. We analysed the sequence variation in six single-copy nuclear loci and three chloroplast (cpDNA) fragments in 497 individuals sampled from...

Jie Gao, Zhi Long Liu, Wei Zhao, Kyle W. Tomlinson, Shang-Wen Xia, Qing-Yin Zeng, Xiao-Ru Wang & Jin Chen
Understanding the effects of the demographic dynamics and environmental heterogeneity on the genomic variation of forest species is important not only for uncovering the evolutionary history of the species but also for predicting their ability to adapt to climate change. In this study, we combined a common garden experiment with range-wide population genomics analyses to infer the demographic history and characterize patterns of local adaptation in a subtropical oak species, Quercus acutissima. We scanned about...

Functional investigation of monoterpenes for improved understanding of the relationship between hosts and bark beetle

Jiaxing Fang
Spruce bark beetle (Ips typographus L.) is the most destructive insect pest of spruce forest in Eurasia. However, contact toxicity, in vivo metabolism, and ecological functions of host monoterpenes are poorly understood at the spruce–bark beetle–predator tritrophic level. Spruce monoterpenes including S-(–)-α-pinene, R-(+)-α-pinene, and myrcene showed contact toxicity to spruce bark beetle, with LD50 values ranging from 24–36 μg/mg. When topically treated with S-(–)-α-pinene or R-(+)-α-pinene, the amount of volatile metabolites [S-(–)-cis-verbenol, 4S-(+)-/4R-(–)-trans-verbenol, and R-(+)-/S-(–)-verbenone]...

Genomic SSR and EST-SSR markers for phylogenetic and pedigree reconstruction: A comparison in sea buckthorn

Yan-Fei Zeng, Jian-Guo Zhang, Luo-Yun Wang, Shan-Shan Li, Tian-Yi Wang, Cai-Yun He & Hong-Mei Luo
Simple sequence repeat (SSR) markers play an important role in genetic and molecular breeding programs, especially for non-model species. We identified SSRs from expressed sequence tags (EST-SSRs) and whole genome sequences (gSSRs), by analyzing the transcriptome and genome of the Mongolian sea buckthorn (Hippophae rhamnoides subsp. Mongolica) cultivar ‘Sunny’. Using the same number of loci, EST-SSRs showed higher transferability to Hippophae than gSSRs, and phylogenetic trees based on EST-SSRs demonstrated higher resolution for classifying Hippophae...

Data from: Variations in ratio and loads of soil nitrogen and phosphorus explain the coexistence of dominant tree species in a boreal forest of Xinjiang, northwest China

Yi Ding, Pengcheng Liu, Wendong Wang, Zhiqiang Bai, Zhongjun Guo, Wei Ren, Yue Xu, Jihong Huang, Jie Yao & Runguo Zang
The resource ratio hypothesis (RRH) and the nutrient-load hypothesis (NLH) state that species coexistence is driven by the ratios and loads (contents) of multiple limiting resources, respectively. However, roles of resource ratios and loads to mature forest ecosystems remains unclear. Data were collected within 300 quadrats (20m×20m) spread across a 12 ha plot of boreal forest in the Kanas of Xinjiang, northwest China. We used torus translation tests to analyze the associations of dominant tree...

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...

Han Yan, Grégoire T. Freschet, Huimin Wang, J. Aaron Hogan, Shenggong Li, Oscar J. Valverde-Barrantes, Xiaoli Fu, Ruili Wang, Xiaoqin Dai, Lei Jiang, Shengwang Meng, Fengting Yang, Miaomiao Zhang & Liang Kou
The root economics space (RES) is multidimensional and largely shaped by belowground biotic and abiotic influences. However, how root-fungal symbioses and edaphic fertility drive this complexity remains unclear. Here, we measured absorptive root traits of 112 tree species in temperate and subtropical forests of China, including traits linked to functional differences between arbuscular mycorrhizal (AM) and ectomycorrhizal (ECM) hosts. Our data, from known mycorrhizal tree species, revealed a ‘fungal-symbiosis’ dimension distinguishing AM from ECM species....

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: Contrasting leaf trait responses of conifer and broadleaved seedlings to altered resource availability are linked to resource strategies

Barbara Moser, Yan-Li Zhang, Mai-He Li, Thomas Wohlgemuth, Jing-Pin Lei & Christoph Bachofen
(1) Understanding tree seedling responses to water, nutrient and light availability is crucial to precisely predict potential shifts in composition and structure of forest communities under future climatic conditions. (2) We exposed seedlings of widespread central European tree species with contrasting leaf habit, deciduous broadleaves (DB) and evergreen conifers (EC), to factorial combinations of manipulated precipitation (100% and 50% of ambient), shade (40% and 60% of full sunlight) and nutrient availability (low and high NPK),...

Impacts of growth form and phylogenetic relatedness on seed germination: a large-scale analysis of a subtropical regional flora

JuHong Wang, GeXi Xu, Chen Wen, YanBo Ma, Wei Qi, ChunHui Zhang & XianLiang Cui
Plant regeneration strategy plays a critical role in species survival and can be used as a proxy for the evolutionary response of species to climate change. However, information on the effects of key plant traits and phylogenetic relatedness on seed germination is limited at large regional scales that vary in climate. To test the hypotheses that phylogenetic niche conservatism plays a critical force in shaping seed ecophysiological traits across species, and also drives their response...

Yuguang Zhang, Xiao Liu, Jing Cong, Hui Lu, Yuyu Sheng, Xiulei Wang, Diqiang Li, Xueduan Liu, Huaqun Yin, Jizhong Zhou & Ye Deng
Land-cover change has long been recognized as having marked effect on the amount of soil organic carbon (SOC). However, the microbially-mediated processes and mechanisms on SOC are still unclear. In this study, the soil samples in a degenerative succession from alpine meadow to alpine steppe meadow in the Qinghai-Tibetan Plateau were analyzed using high-throughput technologies, including Illumina sequencing and GeoChip functional gene arrays. The soil microbial community structure and diversity were significantly (P < 0.05)...

Data from: Mining from transcriptomes: 315 single-copy orthologous genes concatenated for the phylogenetic analyses of Orchidaceae

Hua Deng, Guo-Qiang Zhang, Min Lin, Yan Wang & Zhong-Jian Liu
Phylogenetic relationships are hotspots for orchid studies with controversial standpoints. Traditionally, the phylogenies of orchids are based on morphology and subjective factors. Although more reliable than classic phylogenic analyses, the current methods are based on a few gene markers and PCR amplification, which are labor intensive and cannot identify the placement of some species with degenerated plastid genomes. Therefore, a more efficient, labor-saving and reliable method is needed for phylogenic analysis. Here, we present a...

Data from: Habitat hotspots of common and rare tropical species along climatic and edaphic gradients

Han Xu, Suqin Fang & Matteo Detto
1. Understanding coexistence in high biodiversity ecosystems requires knowledge of how rare and common species share the multidimensional environmental space. Climatic and edaphic conditions can provide a plethora of habitats, supporting different compositional and structural communities where species can adapt and differentiate. 2. We used a large dataset consisting of 580 tropical tree species sampled in 163 25×25 m quadrats along an altitudinal gradient covering an area of 160 km2 of tropical rainforest in Jianfengling...

Geshere Abdisa Gurmesa, Ang Wang, Shanlong Li, Shushi Peng, Wim De Vries, Per Gundersen, Philippe Ciais, Oliver L Phillips, Erik Hobbie, Weixing Zhu, Knute Nadelhoffer, Yi Xi, Edith Bai, Tao Sun, Dexiang Chen, Wenjun Zhou, Yiping Zhang, Yingrong Guo, Jiaojun Zhu, Lei Duan, Dejun Li, Keisuke Koba, Enzai Du, Guoyi Zhou, Xingguo Han … & Yunting Fang
The impacts of enhanced nitrogen (N) deposition on global forest carbon (C) sink and other ecosystem services may depend on whether N is deposited in reduced (mainly as ammonium) or oxidized forms (mainly as nitrate) and the subsequent fate of each. However, the fates of the two key reactive N forms and its contribution to forest C sink is unclear. We conducted ecosystem-scale paired 15N-labelling experiments in nine forests across China to quantify N retention...

We provide data on soil for pH, mineral elements, ammonium, nitrate,...

Integrative taxonomy of two thrush complexes (Aves: Turdidae) reveals introgression across sister species

Boyang An, Danyang Yin, Songlin Huang, Tariq Ahmad & Bo Li
The classification of some Turdus species, such as the Naumann’s and dusky thrush complexes and the red-throated and black-throated thrush complexes, is controversial. Herein, we used molecular data and morphological characters to review the taxonomy of these thrush complexes and analyze the genetic differentiation between them. Herein, we examined the genetic characteristics of 13 microsatellite loci in all individuals and total of 129 alleles were detected. In parallel, we have a further judgment on their...

Duncan N. L. Menge, Ryan A. Chisholm, Stuart J. Davies, Kamariah Abu Salim, David Allen, Mauricio Alvarez, Norm Bourg, Warren Y. Brockelman, Sarayudh Bunyavejchewin, Nathalie Butt, Min Cao, Wirong Chanthorn, Wei-Chun Chao, Keith Clay, Richard Condit, Susan Cordell, João Batista Da Silva, H. S. Dattaraja, Ana Cristina Segalin De Andrade, Alexandre A. Oliveira, Jan Den Ouden, Michael Drescher, Christine Fletcher, Christian P. Giardina, C. V. Savitri Gunatilleke … & Tak Fung
Symbiotic nitrogen (N)‐fixing trees can provide large quantities of new N to ecosystems, but only if they are sufficiently abundant. The overall abundance and latitudinal abundance distributions of N‐fixing trees are well characterised in the Americas, but less well outside the Americas. Here, we characterised the abundance of N‐fixing trees in a network of forest plots spanning five continents, ~5,000 tree species and ~4 million trees. The majority of the plots (86%) were in America...

Data from: Geographic variation in the structure of oak hybrid zones provides insights into the dynamics of speciation

Yan-Fei Zeng, Wan-Jin Liao, Rémy J. Petit & Da-Yong Zhang
Studying geographic variation in the rate of hybridization between closely related species could provide a useful window to understand the evolution of reproductive isolation. Reinforcement theory predicts greater prezygotic isolation in areas of prolonged contact between recently diverged species than in areas of recent contact, which implies that old contact zones would be dominated by parental phenotypes with few hybrids (bimodal hybrid zones) whereas recent contact zones would be characterized by hybrid swarms (unimodal hybrid...

Data from: Soil organic matter quantity and quality shape microbial community compositions of subtropical broadleaved forests

Junjun Ding, Yuguang Zhang, Mengmeng Wang, Xin Sun, Jing Cong, Ye Deng, Hui Lu, Tong Yuan, Joy D. Van Nostrand, Diqiang Li, Jizhong Zhou & Yunfeng Yang
As two major forest types in the subtropics, broadleaved evergreen and broadleaved deciduous forests have long interested ecologists. However, little is known about their belowground ecosystems despite their ecological importance in driving biogeochemical cycling. Here, we used Illumina MiSeq sequencing targeting 16S rRNA gene and a microarray named GeoChip targeting functional genes to analyse microbial communities in broadleaved evergreen and deciduous forest soils of Shennongjia Mountain of Central China, a region known as ‘The Oriental...

Data from: Specific leaf area predicts dryland litter decomposition via two mechanisms

Guofang Liu, Lei Wang, Li Jiang, Xu Pan, Zhenying Huang, Ming Dong & Johannes H. C. Cornelissen
1. Litter decomposition plays important roles in carbon and nutrient cycling. In dryland both microbial decomposition and abiotic degradation (by UV light or other forces) drive variation in decomposition rates, but whether and how litter traits and position determine the balance between these processes is poorly understood. 2. We investigated relationships between litter quality and their decomposition rates among diverse plant species in a desert ecosystem in vertically contrasting positions representing distinct decomposition environments driven...

Data from: Effects of stand age, richness and density on productivity in subtropical forests in China

Shuai Ouyang, Wenhua Xiang, Xiangping Wang, Wen-Fa Xiao, Liang Chen, Shenggong Li, Han Sun, Xiangwen Deng, David Forrester, Lixiong Zeng, Pifeng Lei, Xiangdong Lei, Mengmeng Gou & Changhui Peng
1. Forest productivity may be determined not only by biodiversity but also by environmental factors and stand structure attributes. However, the relative importance of these factors in determining productivity is still controversial for subtropical forests. 2. Based on a large dataset from 600 permanent forest inventory plots across subtropical China, we examined the relationship between biodiversity and forest productivity and tested whether stand structural attributes (stand density in terms of trees per ha, age and...

Data from: Spartina alterniflora invasion drastically increases methane production potential by shifting methanogenesis from hydrogenotrophic to methylotrophic pathway in a coastal marsh

Junji Yuan, Deyan Liu, Ji Yang, Jian Xiang, Yongxin Lin, Ming Wu & Weixin Ding
1. Plant invasion can strongly influence carbon (C) cycling processes, thus it may affect climate change by altering C sequestration and greenhouse gas emissions in the invaded ecosystem. Since 1979, the exotic Spartina alterniflora has rapidly expanded in China’s coastal areas, where significant increase in methane (CH4) emissions has been documented from post-invaded sites. However, a mechanistic understanding of the structural and functional changes of associated methanogens accompanying this invasion remains elusive. 2. Here we...

Populus euphratica WRKY1 binds the promoter of PeHA1 to enhance gene expression and salt tolerance

Jun Yao, Zedan Shen, Yanli Zhang, Xia Wu, Jianhui Wang, Gang Sa, Yuhong Zhang, Huilong Zhang, Chen Deng, Jian Liu, Siyuan Hou, Ying Zhang, Yinan Zhang, Nan Zhao, Shurong Deng, Shanzhi Lin, Rui Zhao & Shaoliang Chen
Plasma membrane proton pumps play a crucial role in maintaining ionic homeostasis in salt-resistant Populus euphratica under saline conditions. High levels of NaCl (200 mM) induced PeHA1 expression in P. euphratica roots and leaves. We isolated a 2022-bp promoter fragment upstream of the translational start of PeHA1 from P. euphratica. The promoter-reporter construct PeHA1-pro::GUS was transferred to tobacco plants, demonstrating that β-glucuronidase activities increased in root, leaf, and stem tissues under salt stress. DNA affinity...
