Data from: Pollen limitation, reproductive success and flowering frequency in single-flowered plants

Haiqin Sun, Bao-Qiang Huang, Xiao-Hong Yu, Chang-Bao Tian, Qi-Xuan Peng & De-Jun An
1. Flowering plants exhibit striking interspecific and intraspecific variation in flower number, which strongly influences the reproductive success of animal-pollinated plants. However, the reproductive consequences of producing a single flower are poorly understood. 2. Here, we test if plants producing a single flower have a reproductive disadvantage compared to plants producing multiple flowers by combining field investigation of five deceptive orchids and a survey of published literature. Pollen limitation was estimated by comparing fruit production...

Data from: Dianyuea gen. nov. (Salicaceae: Scyphostegioideae) from southwestern China

Ce Shang, Shuai Liao, Yong-Jie Guo & Zhi-Xiang Zhang
Dianyuea C. Shang, S. Liao & Z. X. Zhang, a new monotypic genus of Salicaceae based on Flacourtia turbinata H. J. Dong & H. Peng, is described and illustrated. Morphologically, Dianyuea differs from Flacourtia Comm. ex L'Hér. by having six connate stamens, basal placentation and lobed seed appendages. All those features indicate that Dianyuea is allied with Scyphostegia Stapf. A molecular phylogenetic analysis using plastid trnL-F, matK, and rbcL sequence data for representatives of 16...

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: Speciation history of a species complex of Primulina eburnea (Gesneriaceae) from limestone karsts of south China, a biodiversity hotspot

Jing Wang, Bin Ai, Hanghui Kong & Ming Kang
Limestone karsts in southern China are characterized by high edaphic and topographic heterogeneity and host high levels of species richness and endemism. However, the evolutionary mechanisms for generating such biodiversity remain poorly understood. Here, we performed species delimitation, population genetic analyses, simulations of gene flow, and analyses of floral morphological traits to infer the geographic history of speciation in a species complex of Primulina eburnea from limestone karsts of south China. Using Bayesian species delimitation,...

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: Savannahs of Asia: evidence for antiquity, biogeography and an uncertain future

Jayashree Ratnam, Kyle W. Tomlinson, Dina N. Rasquinha & Mahesh Sankaran
The savannahs of Asia remain locally unrecognized as distinctive ecosystems, and continue to be viewed as degraded forests or seasonally dry tropical forests. These colonial-era legacies are problematic, because they fail to recognize the unique diversity of Asian savannahs and the critical roles of fire and herbivory in maintaining ecosystem health and diversity. In this review, we show that: the palaeo-historical evidence suggests that the savannahs of Asia have existed for at least 1 million...

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: Tradeoff between physical and chemical defense in plant seeds is mediated by seed mass

Bo Wang, Joseph S. Phillips & Kyle W. Tomlinson
Plants have evolved both physical and chemical defenses to make the nutrients of attacked organs difficult to access or more toxic to resist animal consumption or/and pathogen attack. Although it is intuitive that a tradeoff could exist between physical and chemical defenses because of finite defense resources, many studies have failed to detect this tradeoff. We hypothesized that tradeoff between physical and chemical defenses in individual organs was mediated by the total resource allocation to...

Data from: Facilitation by leguminous shrubs increases along a precipitation gradient

Hai-Yang Zhang, Xiao-Tao Lü, Alan K. Knapp, Henrik Hartmann, Edith Bai, Xiao-Bo Wang, Zheng-Wen Wang, Xiao-Guang Wang, Qiang Yu & Xing-Guo Han
Combining nutrient dynamics (plant nutrient uptake and soil fertility) can help uncover mechanisms of shrub-grass interactions and assess the validity of the stress-gradient hypothesis, which predicts that facilitation between plants increases in stressful environments. However, how facilitation via shrub-mediated nutrient increases varies with precipitation is poorly resolved. We first synthesized a global dataset from 66 studies and evaluated how shrubs affected soil organic carbon (C) and nitrogen (N) in grasslands along a precipitation gradient. We...

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: 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: Nutritional imbalance suppresses migratory phenotypes of the Mongolian locust (Oedaleus asiaticus)

Arianne J. Cease, Jon F. Harrison, Shuguang Hao, Danielle C. Niren, Guangming Zhang, Le Kang, James S. Elser & James J. Elser
For many species, migration evolves to allow organisms to access better resources. However, the proximate factors that trigger these developmental changes, and how and why these vary across species, remain poorly understood. One prominent hypothesis is that poor-quality food promotes development of migratory phenotypes and this has been clearly shown for some polyphenic insects. In other animals, particularly long-distance bird migrants, it is clear that high-quality food is required to prepare animals for a successful...

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: Plant defense negates pathogen manipulation of vector behavior

Baiming Liu, Evan L. Preisser, Xiaobin Shi, Huaitong Wu, Chuanyou Li, Wen Xie, Shaoli Wang, Qingjun Wu & Youjun Zhang
1. Although many vector-borne plant pathogens can alter vector behavior to the pathogen's benefit, how plants might counter such manipulation is unknown. 2. In the Tomato yellow leaf curl virus (‘TYLCV’)-Bemisia tabaci-tomato interaction, TYLCV-mediated changes in Bemisia feeding improves viral uptake and transmission. We tested how jasmonic acid (‘JA’), a central regulator of plant anti-herbivore defenses, affected the ability of TYLCV to (A) manipulate Bemisia behavior; and (B) infect plants. 3. Viruliferous Bemisia fed much...

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: Changes in soil microbial communities due to biological invasions can reduce allelopathic effects

Yang-Ping Li, Yu-Long Feng, Zong-Li Kang, Yu-Long Zheng, Jiao-Lin Zhang & Ya-Jun Chen
Summary 1. Soil microbes are important in mediating allelopathic interactions between invasive and native plants in the field. However, it was not known how these interactions vary in the process of biological invasions and the effects of soil microbes. Knowing these may facilitate understanding dynamics and mechanisms of biological invasions and managing invaded ecosystems. 2. We conducted competition and seed germination experiments to determine the allelopathic effects of Ageratina adenophora in soils from 42 sites...

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: The first species of Hapalodectes (Mesonychia, Mammalia) from the middle Paleocene of China (Qianshan Basin, Anhui Province) sheds light on the initial radiation of hapalodectids

Floréal Solé, Eric De Bast, Jian Yang, Cheng-Sen Li & Thierry Smith
A lower jaw of the mesonychian Hapalodectes is reported from Nongshanian sediments (Upper Doumu Formation; middle Paleocene) of the Qianshan Basin (Anhui Province, China). The fragmentary mandible is only the third specimen of Hapalodectidae discovered in Paleocene deposits, and the first in south east China; it is moreover the oldest, the two other specimens having been found in Gashatan (late Paleocene) localities. The premolars and molars of the new fossil are morphologically similar to Hapalodectes...
