Data from: Home-field advantages of litter decomposition increase with increasing N deposition rates: a litter and soil perspective

Ying-Bin Li, Qi Li, Jun-Jie Yang, Xiao-Tao Lv, Wen-Ju Liang, Xing-Guo Han & T. Martijn Bezemer
1. Differences in litter quality and in soil microbial community composition can influence the litter decomposition and “home-field advantage” (HFA). However, our knowledge about the relative role of litter and soil characteristics on litter decomposition and HFA effects is still limited, especially under long-term N deposition. 2. We collected soil and two types of litter (monospecific and mixed species litter) from five replicate plots from a long-term N-deposition field experiment with seven N-addition treatments (0,...

Data from: Divergence in strategies for coping with winter embolism among co-occurring temperate tree species: the role of positive xylem pressure, wood type and tree stature

Cun-Yang Niu, Frederick C. Meinzer & Guang-You Hao
1. In temperate ecosystems, freeze-thaw events are an important environmental stress that can induce severe xylem embolism (i.e. clogging of conduits by air bubbles) in overwintering organs of trees. However, no comparative studies of different adaptive strategies among sympatric tree species for coping with winter embolism have examined the potential role of the presence or absence of embolism refilling by positive xylem pressure. 2. We evaluated the degree of winter embolism and hydraulic architecture traits...

Data from: Long-term antagonistic effect of increased precipitation and nitrogen addition on soil respiration in a semiarid steppe

Hongyan Han, Yue Du, Dafeng Hui, Lin Jiang, Mingxing Zhong & Shiqiang Wan
Changes in water and nitrogen (N) availability due to climate change and atmospheric N deposition could have significant effects on soil respiration, a major pathway of carbon (C) loss from terrestrial ecosystems. A manipulative experiment simulating increased precipitation and atmospheric N deposition has been conducted for 9 years (2005–2013) in a semiarid grassland in Mongolian Plateau, China. Increased precipitation and N addition interactively affect soil respiration through the 9 years. The interactions demonstrated that N...

Data from: DNA metabarcoding reveals that 200-μm-size-fractionated filtering is unable to discriminate between planktonic microbial and large eukaryotes

Lemian Liu, Min Liu, David M. Wilkinson, Huihuang Chen, Xiaoqing Yu & Yang Jun
Microeukaryotic plankton (0.2–200 μm) are critical components of aquatic ecosystems and key players in global ecological processes. High-throughput sequencing is currently revolutionizing their study on an unprecedented scale. However, it is currently unclear whether we can accurately, effectively and quantitatively depict the microeukaryotic plankton communities using traditional size-fractionated filtering combined with molecular methods. To address this, we analysed the eukaryotic plankton communities both with, and without, prefiltering with a 200 μm pore-size sieve –by using...

Data from: Control of proline accumulation under drought via a novel pathway comprising the histone methylase CAU1 and the transcription factor ANAC055

Yanlei Fu, Hailing Ma, Siying Chen, Tianyu Gu & Jiming Gong
Proline plays a crucial role in the drought stress response in plants. However, there are still gaps in our knowledge about the molecular mechanisms that regulate proline metabolism under drought stress. Here, we report that the histone methylase encoded by CAU1, which is genetically upstream of P5CS1 (encoding the proline biosynthetic enzyme Δ1-pyrroline-5-carboxylate synthetase 1), plays a crucial role in proline-mediated drought tolerance. We determined that the transcript level of CAU1 decreased while that of...

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: More invaders do not result in heavier impacts: the effects of nonnative bullfrogs on native anurans are mitigated by high densities of nonnative crayfish

Xuan Liu, Supen Wang, Zunwei Ke, Chaoyuan Cheng, Yihua Wang, Fang Zhang, Feng Xu, Xianping Li, Xu Gao, Changnan Jin, Wei Zhu, Shaofei Yan & Yiming Li
1.With accelerating species introductions in an era of globalization, co-occurring alien species have become increasingly common. Understanding the combined ecological impacts of multiple invaders is not only crucial for wildlife managers attempting to ameliorate biodiversity loss but also provides key insights into invasion success and species coexistence mechanisms in natural ecosystems. Compared with much attentions given to single invader impacts, little is known about the impacts of multiple co-occurring invaders. 2.The American bullfrog (Lithobates catesbeianus...

Data from: Warm–cold colonization: response of oaks to uplift of the Himalaya–Hengduan Mountains

Hong-Hu Meng, Tao Su, Xiao-Yang Gao, Jie Li, Xiao-Long Jiang, Hang Sun & Zhe-Kun Zhou
Clarifying the relationship between distribution patterns of organisms and geological events is critical to understanding the impact of environmental changes on organismal evolution. Quercus sect. Heterobalanus is now distributed across the Himalaya–Hengduan Mountains (HHM) and warm lowland in East China, yet how the distribution patterns of this group changed in response to the HHM uplift remains largely unknown. This study examines the effect of tectonic events in the HHM region on the oaks, providing a...

Data from: Female lizards choose warm, moist nests that improve embryonic survivorship and offspring fitness

Shu-Ran Li, Xin Hao, Yang Wang, Bao-Jun Sun, Jun-Huai Bi, Yong-Pu Zhang, Fredric J. Janzen & Wei-Guo Du
1. The fitness consequence of maternal nest-site choice has attracted increasing scientific attention, but field studies identifying the long-term effects of nest-site choice on offspring survival and reproductive success are still rare in vertebrates. 2. To investigate the consequences of nest-site choice in lizards, we quantified the thermal and hydric conditions of nest sites that were chosen by female toad-headed agama (Phrynocephalus przewalskii) in the desert steppe of northern China. We also determined the effect...

Data from: Variation of stomatal traits from cold-temperate to tropical forests and association with water use efficiency

Congcong Liu, Nianpeng He, Jiahui Zhang, Ying Li, Qiufeng Wang, Lawren Sack & Guirui Yu
1.Stomata control carbon and water vapor exchange between leaves and the atmosphere, thus it can influence water use efficiency and reflect plant adaptation to climate. However, the spatial patterns of leaf stomatal traits and relationships between stomatal trait and water use efficiency across natural communities remain unclear. 2.We measured stomatal density, stomatal size, and stomatal area fraction for 737 plant species from nine forests ranging from tropical to cold-temperate forests. 3.Stomatal density, stomatal size, and...

Data from: Variation in leaf anatomical traits from tropical to cold-temperate forests and linkage to ecosystem functions

Nianpeng He, Congcong Liu, Miao Tian, Meiling Li, Hao Yang, Guirui Yu, Dali Guo, Melinda D. Smith, Qiang Yu & Jihua Hou
1. Leaf anatomical traits may reflect plant's adaption to environmental changes and influence ecosystem functions, as they regulate light absorption and gas exchange to some extent. Here, we hypothesized that leaf anatomical traits were closely related to gross primary productivity (GPP) because photosynthesis commonly occurs in the chloroplasts of palisade and spongy tissues in leaf. 2. Eight leaf anatomical traits were measured in 916 plant species inhabiting from tropical to cold-temperate forests in eastern China:...

Data from: The role of transcriptomes linked with responses to light environment on seedling mortality in a subtropical forest, China

Baocai Han, Maria Natalia Umana, Xiangcheng Mi, Xiaojuan Liu, Lei Chen, Yunquan Wang, Yu Liang, Wei Wei & Keping Ma
Differences in seedling survival in trees have a lasting imprint on seedling, juvenile and adult community structure. Identifying the drivers of these differences, therefore, is a critical research objective that ultimately requires knowledge regarding how organismal function interacts with the local environment to influence survival rates. In tree communities, differences in light use strategies are frequently invoked to explain differences in seedling demographic performance through growth and survival trade-offs. For example, shade-tolerant species grow slowly...

Data from: Contrasting responses of phosphatase kinetic parameters to nitrogen and phosphorus additions in forest soils

Xinyu Zhang, Yang Yang, Chuang Zhang, Shuli Niu, Guirui Yu, Huimin Wang, Evgenia Blagodatskaya, Yakov Kuzyakov, Dashuan Tian, Yuqian Tang, Shuang Liu & Xiaomin Sun
1. Global changes include increasing nitrogen (N) and phosphorus (P) deposition, which affect microbial nutrient demand and biogeochemical cycles. The responses of P-mineralizing enzymes to these global change components are poorly defined and are not specified in forest soils differing in P content. 2. We chose one site in a P-rich and two sites in P-poor forests and established sixteen 20 × 20 m plots at each site. Control, either N only, P only, or...

Data from: Effects of extreme temperatures on the growth and photosynthesis of invasive Bidens alba and its native congener B. biternata

Mao-Feng Yue, S. Luke Flory, Li Feng, Wan-Hui Ye, Hao Shen, Xing-Shan Tian & Zhang-Ming Wang
Temperatures are expected to fluctuate widely under climate change but little is known about how extreme temperatures might affect the physiology and performance of invasive compared to native plant species. In this study, we evaluated the effects of high (40/35oC) and low (10/5oC) temperature regimes on the growth and photosynthesis of the invasive Asteraceae species Bidens alba and its native congener B. biternata using a growth chamber experiment. Results showed that invasive B. alba had...

Data from: Pathogen richness and abundance predict patterns of adaptive MHC variation in insular amphibians

Supen Wang, Conghui Liu, Anthony B. Wilson, Na Zhao, Xianping Li, Wei Zhu, Xu Gao, Xuan Liu & Yiming Li
The identification of the factors responsible for genetic variation and differentiation at adaptive loci can provide important insights into the evolutionary process, and is crucial for the effective management of threatened species. We studied the impact of environmental viral richness and abundance on functional diversity and differentiation of the MHC class Ia locus in populations of the black-spotted pond frog (Pelophylax nigromaculatus), an IUCN-listed species, on 24 land-bridge islands of the Zhoushan Archipelago and 3...

Data from: High nighttime humidity and dissolved organic carbon content support rapid decomposition of standing litter in a semi-arid landscape

Jing Wang, Lingli Liu, Xin Wang, Sen Yang, Beibei Zhang, Ping Li, Chunlian Qiao, Meifeng Deng & Weixing Liu
1. Litter in arid and semi-arid ecosystems usually exhibits a prolonged standing dead phase after senescence; however, we know little about the ways in which abiotic and microbial processes affect standing litter decomposition. 2. We conducted a 26-month (in situ) decomposition experiment in a steppe to investigate the potential mechanisms governing the decomposition of standing litter, and a 192-day laboratory incubation experiment to further explore the impacts of the standing dead stage on the subsequent...

Data from: Population transcriptomes reveal synergistic responses of DNA polymorphism and RNA expression to extreme environments on the Qinghai–Tibetan Plateau in a predatory bird

Shengkai Pan, Tongzuo Zhang, Zhengqin Rong, Li Hu, Zhongru Gu, Qi Wu, Shanshan Dong, Qiong Liu, Zhenzhen Lin, Lucia Deutschova, Xin-Hai Li, Andrew Dixon, Michael W. Bruford, Xiangjiang Zhan & Xinhai Li
Low oxygen and temperature pose key physiological challenges for endotherms living on the Qinghai–Tibetan Plateau (QTP). Molecular adaptations to high-altitude living have been detected in the genomes of Tibetans, their domesticated animals and a few wild species, but the contribution of transcriptional variation to altitudinal adaptation remains to be determined. Here we studied a top QTP predator, the saker falcon, and analysed how the transcriptome has become modified to cope with the stresses of hypoxia...

Data from: Distinct microbial communities in the active and permafrost layers on the Tibetan Plateau

Yongliang Chen, Ye Deng, Jinzhi Ding, Hangwei Hu, Tianle Xu, Fei Li, Guibiao Yang, Yuanhe Yang, Hang-Wei Hu, Gui-Biao Yang, Yuan-He Yang & Tian-Le Xu
Permafrost represents an important understudied genetic resource. Soil microorganisms play important roles in regulating biogeochemical cycles and maintaining ecosystem function. However, our knowledge of patterns and drivers of permafrost microbial communities is limited over broad geographic scales. Using high-throughput Illumina sequencing, this study compared soil bacterial, archaeal and fungal communities between the active and permafrost layers on the Tibetan Plateau. Our results indicated that microbial alpha diversity was significantly higher in the active layer than...

Data from: Contrasting effects of ammonium and nitrate additions on the biomass of soil microbial communities and enzyme activities in subtropical China

Chuang Zhang, Xin-Yu Zhang, Hong-Tao Zhou, Liang Kou, Yang Yang, Xue-Fa Wen, Sheng-Gong Li, Hui-Min Wang, Xiao-Min Sun & Hong-Tao Zou
The nitrate to ammonium ratios in nitrogen (N) compounds in wet atmospheric deposits have increased over the recent past, which is a cause for some concern as the individual effects of nitrate and ammonium deposition on the biomass of different soil microbial communities and enzyme activities are still poorly defined. We established a field experiment and applied ammonium (NH4Cl) and nitrate (NaNO3) at monthly intervals over a period of 4 years. We collected soil samples...

Data from: Does plant diversity increase top–down control of herbivorous insects in tropical forest?

Bruno Leles, Xiao Xue, Bonifacio O. Pasion, Akihiro Nakamura & Kyle W. Tomlinson
Higher trophic level interactions are key mediators of ecosystem functioning in tropical forests. A rich body of theory has been developed to predict the effects of plant diversity on communities at higher trophic levels and the mechanisms underlying such effects. The ’enemies hypothesis’ states that predators exert more effective top–down control of herbivorous insects with increasing plant diversity. Support for this hypothesis has been found in temperate forests and agroecosystems, but remains understudied in tropical...

Data from: Root elemental composition in Chinese forests: implications for biogeochemical niche differentiation

Ning Zhao, Hui Liu, Qiufeng Wang, Ruili Wang, Zhiwei Xu, Cui Jiao, Jianxing Zhu, Guirui Yu, Nianpeng He, Huiming Liu & Cuicui Jiao
1. Trait-based community analysis provides a new approach to integrate functional ecology with community ecology. However, our understanding of the linkages between root chemical traits and community chemical diversity and assembly is still in its infancy. 2. Environmental filtering and niche differentiation are two opposite driving forces of community assembly based on deterministic niche processes. We hypothesize that environmental filtering is a strong driver of root chemical assembly at a large spatial scale, whereas biogeochemical...

Data from: Glucocorticoid induces incoordination between glutamatergic and GABAergic neurons in the amygdala

Guang-Yan Wang, Zhaoming Zhu, Shan Cui, Jin-Hui Wang & Zhao-Ming Zhu
Background: Stressful life leads to mood disorders. Chronic mild stress is presumably major etiology for depression, and acute severe stress leads to anxiety. These stressful situations may impair hypothalamus-pituitary-adrenal axis and in turn induce synapse dysfunction. However, it remains elusive how the stress hormones mess up subcellular compartments and interactions between excitatory and inhibitory neurons, which we have investigated in mouse amygdala, a structure related to emotional states. Methods and Results: Dexamethasone was chronically given...

Data from: Rungia sinothailandica sp. nov. (Acanthaceae) from China and Thailand

Zhe-Li Lin & Yun-Fei Deng
Rungia sinothailandica (Acanthaceae), a new species from Yunnan, China and Chiang Rai, Thailand is described and illustrated. A colour plate, line drawing and distribution map of R. sinothailandica are provided. Rungia sinothailandica is similar to R. pinpienensis H. S. Lo, but differs in the broadly ovate sterile bracts and obovate-elliptic fertile bracts, the crispate and tawny bracts margin, the 2-lobed upper lip of the corolla and puberulent capsule. It is also similar to R. burmanica...

Data from: The microbially-mediated soil organic carbon loss under degenerative succession in an alpine meadow

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: δ18O-derived incubation temperatures of oviraptorosaur eggs

Romain Amiot, Xu Wang, Shuo Wang, Christophe Lécuyer, Jean-Michel Mazin, Jinyou Mo, Jean-Pierre Flandrois, François Fourel, Xiaolin Wang, Xing Xu, Zhijun Zhang & Zhonghe Zhou
In order to determine the incubation temperature of eggs laid by non-avian dinosaurs, we analysed the oxygen isotope compositions of both eggshell carbonate (δ18Oc) and embryo bone phosphate (δ18Op) from seven oviraptorosaur eggs with preserved in ovo embryo bones. These eggs come from the Upper Cretaceous Nanxiong Formation of Jiangxi Province, China. Oviraptorosaur theropods were selected because of their known brooding behaviour as evidenced by preserved adult specimens fossilized in brooding posture on their clutch....
