Data from: Reconciling multiple impacts of nitrogen enrichment on soil carbon: plant, microbial, and geochemical controls

Chenglong Ye, Dima Chen, Steven J. Hall, Shang Pan, Xuebin Yan, Tongshuo Bai, Hui Guo, Yi Zhang, Yongfei Bai & Shuijin Hu
Impacts of reactive nitrogen (N) inputs on ecosystem carbon (C) dynamics are highly variable, and the underlying mechanisms remain unclear. Here, we proposed a new conceptual framework that integrates plant, microbial, and geochemical mechanisms to reconcile diverse and contrasting impacts of N on soil C. This framework was tested using long-term N enrichment and acid addition experiments in a Mongolian steppe grassland. Distinct mechanisms could explain effects of N on particulate and mineral-associated soil C...

Data from: Litter carbon and nutrient chemistry control the magnitude of soil priming effect

Lin Chao, Yanyan Liu, Grégoire Freschet, Weidong Zhang, Xin Yu, Wenhui Zheng, Xin Guan, Qingpeng Yang, Longchi Chen, Feike Dijkstra, Silong Wang & Feike A. Dijkstra
1. Plant litter inputs can promote the decomposition of soil organic matter (OM) through the priming effect (PE). However, whereas leaf litter chemistry has long been identified as the primary driver of litter decomposition within biomes worldwide, little is known about how litter chemical traits influence the occurrence and strength of the PE. 2. Here, we studied the effects of 15 co-occurring C3 leaf litters of contrasting chemistry on C4 soil respiration by analyzing changes...

Data from: A grazing Gomphotherium in Middle Miocene Central Asia, 10 million years prior to the origin of the Elephantidae

Yan Wu, Tao Deng, Yaowu Hu, Jiao Ma, Xinying Zhou, Limi Mao, Hanwen Zhang, Jie Ye & Shi-Qi Wang
Feeding preference of fossil herbivorous mammals, concerning the coevolution of mammalian and floral ecosystems, has become of key research interest. In this paper, phytoliths in dental calculus from two gomphotheriid proboscideans of the middle Miocene Junggar Basin, Central Asia, have been identified, suggesting that Gomphotherium connexum was a mixed feeder, while the phytoliths from G. steinheimense indicates grazing preference. This is the earliest-known proboscidean with a predominantly grazing habit. These results are further confirmed by...

Manichanh Satdichanh, Huaixia Ma, Kai Yan, Gbadamassi G.O. Dossa, Leigh Winowiecki, Tor-Gunnar Vågen, Anja Gassner, Jianchu Xu & Rhett D. Harrison
1. Enhancing knowledge on the role of evolutionary history during forest succession and its relationship with ecosystem function is particularly relevant in the context of forest landscape restoration for climate change mitigation and adaptation. 2. We used fine resolution vegetation and environmental data (soil, elevation and slope) from two large-scale surveys (320 x 1000 m2 plots in two 10 km x 10 km blocks) in the Upper Mekong to quantify (1) the role of abiotic...

Data from: Ecological correlates of Himalayan musk deer Moschus leucogaster

Paras Bikram Singh, Pradip Saud, Kumar Mainali, Doug Cram, Arjun Thapa, Nar Bahadur Chhetri, Laxman P. Poudyal, Hem Sagar Baral, Zhigang Jiang & Douglas Cram
Himalayan musk deer (Moschus leucogaster; hereafter musk deer) are endangered as a result of poaching and habitat loss. The species is nocturnal, crepuscular and elusive, making direct observation of habitat use and behavior difficult. However, musk deer establish and repeatedly use the same latrines for defecation. To quantify musk deer habitat correlates, we used observational spatial data based on presence-absence of musk deer latrines, as well as a range of fine spatial-scale ecological covariates. To...

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: Congruent species delimitation of two controversial gold-thread nanmu tree species based on morphological and restriction site-associated DNA sequencing data

Xin Ding, Jianhua Xiao, Lang Li, John G Canran, Jie Li, John G. Conran & Jian Hua Xiao
Species delimitation is fundamental to conservation and sustainable use of economically important forest tree species. However, the delimitation of two highly valued gold-thread nanmu species (Phoebe bournei and P. zhennan) has been confusing and debated. To address this problem, we integrated morphology and restriction site-associated DNA sequencing (RADseq) to define their species boundaries. We obtained highly consistent results from both data sets, supporting two distinct lineages corresponding to P. bournei and P. zhennan. In Phoebe...

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: Spatial-temporal variability and related factors of soil organic carbon in Henan province

Congzhi Zhang, Wei Li, Zhanhui Zhao, Yanfang Zhou, Jiabao Zhang & Qicong Wu
Spatial variability and influence factors are important to evaluate soil organic carbon(SOC) and the carbon pool in large areas. In the present study, sampling was conducted from May to November 2011 in Henan province, a typical agricultural region of central China, to study the effects of soil properties and anthropogenic factors on SOC variability in cropland. Physicochemical properties of soil samples were analyzed, which were collected at 280 sites from the surface layer (at a...

Data from: Removal of Cr6+ ions from water by electricosorption on modified activated carbon fibre felt

Xinkun Zhao, Bingxin Jia, Qianqian Sun, Gao-Jie Jiao, Lili Liu, Diao She & Gaojie Jiao
Electrosorption is a novel desalination technique that has many advantages in the treatment of sewage. However, commercially available activated carbon electrodes for electrosorption commonly have low microporosity, poor molding performance, and low adsorption and regeneration efficiency. Here we evaluated a novel adsorbent material, activated carbon fiber felt (ACFF), for electrosorption of chromium ions (Cr6+) in sewage treatment. The ACFF was modified with 20% nitric acid and its modified structure was characterized. The modified ACFF was...

Data from: Are vocal characteristics related to leadership patterns in mixed-species bird flocks?

Emilio Pagani-Núñez, Xue Xia, Guy Beauchamp, Ruchuan He, John H.D. Husson, Dan Liang, Eben Goodale & John H. D. Husson
What structures the organization of mixed-species bird flocks, so that some ‘nuclear’ species lead the flocks, and others follow? Previous research has shown that species actively listen to each other, and that leaders are gregarious; such gregarious species tend to make contact calls and hence may be vocally conspicuous. Here we investigated whether vocal characteristics are associated with leadership, using a global dataset of mixed-species flock studies and recordings from sound archives. We first asked...

Data from: The effects of warming and nitrogen addition on ecosystem respiration in a Tibetan alpine meadow: the significance of winter warming

Ning Zong, Shoubao Geng, Cheng Duan, Peili Shi, Xi Chai & Xianzhou Zhang
Global warming has become an indisputable fact on the Tibetan Plateau in the last decades. Alpine ecosystems are very sensitive to global warming, while the impact may depend on the degree of atmospheric nitrogen (N) deposition. Previous studies paid more attention on year-round warming, while the effects of winter warming was still lacking. In this paper, a manipulative experiment consisted of warming and N addition was carried out in an alpine meadow since 2010, and...

Mide Rao, Manuel J. Steinbauer, Xiaoguo Xiang, Minggang Zhang, Xiangcheng Mi, Jin-Tun Zhang, Keping Ma, Jens-Christian Svenning & Jintun Zhang
Subtropical forest is recognized as an important global vegetation type with high levels of plant species richness. However, the mechanisms underlying its diversity remain poorly understood. Here, we assessed the roles of environmental drivers and evolutionary dynamics (time-for-speciation and diversification rate) in shaping species richness patterns across China for a major subtropical plant group, the tea family (Theaceae s.s.) (145 species), at several taxonomic scales. To this end, we assessed the relationships between species richness,...
