‘Social distancing’ between plants may amplify coastal restoration at early stage

Hao Huang, Chi Xu & Quan‐Xing Liu
This dataset contains data and codes from three field experiments described in the paper: “Hao Huang, Chi Xu and Quan-Xing Liu. (2021) ‘Social distancing’ between plants may amplify coastal restoration at early stage, Journal of Applied Ecology, DOI: 10.1111/1365-2664.14044”. The experiment investigates the effects of a factorial combination of three factors: above-ground spatial configurea and below-ground connectivity with low- and high-elevation environmental stress. We test the two species (Scirpus and Spartina) on performance such as...

β diversity among ant communities on fragmented habitat islands: the roles of species trait, phylogeny and abundance

Yuhao Zhao, Nathan Sanders, Juan Liu, Tinghao Jin, Haonan Zhou, Ruisen Lu, Ping Ding & Xingfeng Si
Habitat loss and fragmentation reduce biodiversity and alter species composition in local communities. β diversity describes the variation in species composition between or among communities in fragmented landscapes and has two components: species turnover and nestedness. In this study, we assessed β diversity of ant assemblages on 24 island fragments in the Thousand Island Lake, China. We constructed a species-level phylogenetic tree and measured five morphological traits of all ant species captured. We then assessed...

Diversity and identity of economics traits determine the extent of tree mixture effects on ecosystem productivity

Liting Zheng, Han Chen, Shekhar Biswas, Difeng Bao, Xiaochen Fang, Muhammad Abdullah & Enrong Yan
1. Although both observational and experimental studies have shown that positive tree species diversity-productivity relationships are predominant in global forests, weak or the lack of tree species diversity and productivity relationships also exist. Growing evidence has revealed that ecosystem productivity depends more on the functional characteristics of species than on their number. However, exactly to what extent tree diversity effects on ecosystem productivity are influenced by the variability and composition of functional traits have been...

Source–sink dynamics assists the maintenance of a pollinating wasp

Xin Tong, Yuan-Yuan Ding, Jun-Yin Deng, Rong Wang & Xiao-Yong Chen
Dispersal that unites spatially subdivided populations into a metapopulation with source–sink dynamics is crucial for species persistence in fragmented landscapes. Understanding such dynamics for pollinators is particularly urgent owing to the ongoing global pollination crisis. Here, we investigated the population structure and source–sink dynamics of a pollinating wasp (Wiebesia sp. 3) of Ficus pumila in the Zhoushan Archipelago of China. We found significant asymmetry in the pairwise migrant numbers for 22 of 28 cases on...

Unraveling the roles of various ecological factors in seedling recruitment to facilitate plant regeneration

Yuanyuan Li, Rong Wang & Xiao-Yong Chen
Unraveling the mechanisms causing restricted regeneration and limited distribution range has become a core issue for biodiversity conservation. Anthropogenic disturbances are changing a variety of ecological factors, but how their relative importance varies across multiple regeneration stages is still unclear even in a single species. In this study, we focused on Metasequoia glyptostroboides, a relict species suffering a severely restricted regeneration in the wild, and performed controlled experiments using 54,600 seeds to investigate seedling emergence...

Genetic tracking of density‐dependent adult recruitment: A case study in a subtropical oak

Xin Tong, John D. Nason, Yuan‐Yuan Ding & Xiao-Yong Chen
Density-dependent recruitment is fundamental to understanding species diversity and community dynamics in plants. Although there is compelling evidence that seeds and seedlings die from conspecific negative density dependence (CNDD) as predicted by the Janzen–Connell hypothesis, characterizing adult recruitment remains a challenge for long-living trees. Previous studies have used the decrease of fine-scale spatial genetic structure (FSGS) across life stages to indicate CNDD; however, this has not been tested rigorously. We addressed these challenges by integrating...

Dynamic feedbacks among tree functional traits, termite populations and deadwood turnover

Chao Guo, Bin Tuo, Ci Hang, Enrong Yan & Johannes H. C. Cornelissen
1. Changes in the composition of plant functional traits may affect ecosystem processes through influencing trophic interactions. Bottom-up control by plant species through food availability to animals may vary with time. However, such dynamics and their consequences for deadwood turnover are poorly known for detrital food webs. 2. We introduce a dynamic conceptual model of the feedback of (deadwood-feeding) termite populations, tree functional traits and deadwood decomposition. We hypothesized that tree functional diversity (in terms...

Ecological niche modeling was employed to predict the potential distribution of M. thunbergii during the Last Glacial Maximum (LGM) and the last interglacial period. Nuclear microsatellite and chloroplast markers were...

Influences of the bark economics spectrum and positive termite feedback on bark and xylem decomposition

Bin Tuo, En-Rong Yan, Chao Guo, Hang Ci, Matty P. Berg & Johannes H. C. Cornelissen
The plant economics spectrum integrates trade-offs and covariation in resource economic traits of different plant organs and their consequences for pivotal ecosystem processes, such as decomposition. However, in this concept stems are often considered as one unit ignoring the important functional differences between wood (xylem) and bark. These differences may not only affect the performance of woody plants during their lifetime, but may also have important “afterlife effects”. Specifically, bark quality may strongly affect deadwood...

Conservation of woody species in China under future climate and land-cover changes

Shijia Peng, Jian Zhang, Xiaoling Zhang, Yaoqi Li, Yunpeng Liu & Zhiheng Wang
Climate and land-cover changes are major threats to biodiversity, and their impacts are expected to intensify in the future. Protected areas (PAs) are crucial for biodiversity conservation. However, their effectiveness under future climate and land-cover changes remains to be evaluated. Moreover, the impacts of climate and land-cover changes on multi-dimensions of biodiversity are rarely considered when expanding PAs. Using distributions of 8732 woody species in China and species distribution models, we identified species that will...

Species packing and the latitudinal gradient in local beta-diversity

Ke Cao, Richard Condit, Xiangcheng Mi, Lei Chen, Wubing Xu, David F. R. P. Burslem, Chunrong Cai, Min Cao, Li-Wan Chang, Chengjin Chu, Hu Du, Sisira Ediriweera, C. S. V. Gunatilleke, I. U. A. N. Gunatilleke, Zhanqing Hao, Jinbo Li, Guangze Jin, Buhang Li, Yankun Liu, Yide Li, Michael J. O'Brien, Xiujuan Qiao, Hongwei Ni, Guochun Shen, Xihua Wang … & Jens-Christian Svenning
The decline in species richness at higher latitudes is among the most fundamental patterns in ecology. Whether changes in species composition across space (beta-diversity) contribute to this gradient of overall local species richness (gamma diversity) remains hotly debated. Previous studies that failed to resolve the issue suffered from a well-known tendency for small samples in areas with high gamma-diversity to have inflated measures of beta-diversity. We provide here a novel analytical test, using beta-diversity metrics...

Data from: Effects of climate and topography on the diversity anomaly of plants disjunctly distributed in eastern Asia and eastern North America

Xue Yin, Hong Qian, Xinghua Sui, Minhua Zhang, Lingfeng Mao, Jens-Christian Svenning, Robert E. Ricklefs & Fangliang He
Aim: Differences in physiography have been proposed to explain the diversity anomaly for vascular plants between environmentally similar regions of eastern Asia (EAS) and eastern North America (ENA). Here, we use plant species within disjunct genera to examine whether differences in topography contribute to the diversity anomaly and whether the richness–environment relationships differ between regions. Disjuncts are used to ensure that the diversity anomaly relates to post-disjunction evolution and diversification rather than regional differences in...

To find out which taxa harbor the largest number of undiscovered species and where those species locate. 3. To find out the determinants of province-level mean discovery time and inventory completeness. Location: China Methods We compiled the discovery time and province-level geographic distributions of...

Responses of soil temperature, moisture, and respiration to five-year warming and nitrogen addition in a semi-arid grassland

Jian Song, Jianyang Xia, Dafeng Hui, Mengmei Zheng, Jing Wang, Jingyi Ru, Haidao Wang, Qingshan Zhang, Chao Yang & Shiqiang Wan
How climate warming interacts with atmospheric nitrogen (N) deposition to affect carbon (C) release from soils remains largely elusive, posing a major challenge in projecting climate change‒terrestrial C feedback. As part of a five-year (2006–2010) field manipulative experiment, this study was designed to examine the effects of 24-hour continuous warming and N addition on soil respiration and explore the underlying mechanisms in a semi-arid grassland on the Mongolian Plateau, China. Across the five years and...

Yongyi Luo, Fuqiang Zhai, Yingchun Zhang, Zhiqiang Chen, Mingde Ding, Dajiang Qin, Jinming Yang, Guang Feng & Lu Li
The development of high-performance air filter has become more and more important to public health. However, it has always been very challenging for developing a multifunctional air filter to simultaneously achieve excellent filtration and antibacterial properties. Herein, a versatile air filter was prepared with loading the reduced graphener and Zinc oxide on the superfine glass fiber with the three-dimensional network structure by in-situ sol-gel process followed by calcination, which aims to achieve synergistic high efficiency...

Functional traits explain the consistent resistance of biodiversity to plant invasion under nitrogen enrichment

Shao-Peng Li, Jia Pu, Shu-Ya Fan, Yingtong Wu, Xiang Liu, Yani Meng, Yue Li, Wen-Sheng Shu, Jin-Tian Li & Lin Jiang
Elton’s biotic resistance hypothesis, which posits that diverse communities should be more resistant to biological invasions, has received considerable experimental support. However, it remains unclear whether such a negative diversity–invasibility relationship would persist under anthropogenic environmental change. By using the common ragweed (Ambrosia artemisiifolia) as a model invader, our four-year grassland experiment demonstrated consistently negative relationships between resident species diversity and community invasibility, irrespective of nitrogen addition, a result further supported by a meta-analysis. Importantly,...

Spatial and local environmental factors outperform geo-climatic gradients in structuring taxonomically- and traits-based β‐diversity of benthic algae

Naicheng Wu, Shuchan Zhou, Min Zhang, Wenqi Peng, Kun Guo, Xiaodong Qu & Fengzhi He
Aim: Understanding the variation in biodiversity and its underlying drivers and mechanisms is a core task in biogeography and ecology. In this study, we examined: i) the relative contributions of species replacement (i.e. turnover) and richness difference (i.e. nestedness) to taxonomically- and traits-based β-diversity of stream benthic algae; ii) whether these two facets of β-diversity are correlated with each other; and iii) the relative contributions of local environmental (e.g. water chemistry, flow velocity, habitat quality),...

Data from: Trait hierarchies are stronger than trait dissimilarities in structuring spatial co-occurrence patterns of common tree species in a subtropical forest

Deyi Yin, Yu Liu, Qing Ye, Marc Cadotte & Fangliang He
1. The dissimilarity and hierarchy of trait values that characterize niche and fitness differences, respectively, have been increasingly applied to infer mechanisms driving community assembly and to explain species co-occurrence patterns. Here, we predict that limiting similarity should result in the spatial segregation of functionally similar species, while functionally similar species will be more likely to co-occur either due to environmental filtering or competitive exclusion of inferior competitors (hereafter hierarchical competition). 2. We used a...

Scale-dependent shifts in functional and phylogenetic structure of Mediterranean island plant communities over two centuries

Chunhui Zhang, Marc William Cadotte, Alessandro Chiarucci, Michel Loreau, Charles Willis, Xingfeng Si, Lanping Li & Marcus Cianciaruso
1. Since the Industrial Revolution, the rapid global population and economic expansion has had tremendous impacts on biodiversity across spatial scales, especially for islands. While changes in species richness are easily inferred, the impact of human activity on the underlying community assembly processes has been difficult to ascertain because of lack of long-term community data. 2. Here, we document how the manifestations of plant community assembly have changed over time and space in a Mediterranean...

An invasive species erodes the performance of coastal wetland protected areas

Junlin Ren, Jianshe Chen, Changlin Xu, Johan Van De Koppel, Mads Thomsen, Shi-Yun Qiu, Fangyan Cheng, Wanjuan Song, Quan-Xing Liu, Chi Xu, Junhong Bai, Yihui Zhang, Baoshan Cui, Mark Bertness, Brian Silliman, Bo Li & Qiang He
The world has increasingly relied upon protected areas (PAs) to rescue highly valued ecosystems from human activities, but whether PAs will fare well with bioinvasions remains unknown. By analyzing three decades of seven largest coastal PAs in China, including multiple World Natural Heritage and/or Wetlands of International Importance sites, we show that although PAs are achieving success in rescuing iconic wetlands and critical shorebird habitats from once widespread reclamation, this success is counteracted by escalating...

Land-use and elevation interact to shape bird functional and phylogenetic diversity and structure: Implications for designing optimal agriculture landscapes

Rachakonda Sreekar, Xingfeng Si, Katerina Sam, Jiajia Liu, Salindra Dayananda, Uromi Goodale, Sarath Kotagama & Eben Goodale
Conversion of rainforests into agriculture resulted in massive changes in species diversity and community structure. Although the conservation of the remaining rainforests is of utmost importance, identifying and creating biodiversity-friendly agriculture landscape is vital for preserving biodiversity and their functions. Biodiversity studies in agriculture have often been conducted at low elevations. In this study, we compared the functional diversity (FD), phylogenetic diversity (PD), and community structure of birds along an interacting gradient of land-use (protected...

Mycorrhizal effects on decomposition and soil CO2 flux depend on changes in nitrogen availability during forest succession

Ruiqiang Liu, Yanghui He, Guiyao Zhou, Junjiong Shao, Lingyan Zhou, Huimin Zhou, Nan Li, Bingqian Song, Chao Liang, Enrong Yan, Xiao-Yong Chen, Xihua Wang, Minhuang Wang, Shahla Hosseini Bai, Xuhui Zhou & Richard Phillips
Mycorrhizal fungi play a central role in plant nutrition and nutrient cycling, yet our understanding on their effects on free-living microbes, soil carbon (C) decomposition and soil CO2 fluxes remains limited. Here we used trenches lined with mesh screens of varying sizes to isolate mycorrhizal hyphal effects on soil C dynamics in subtropical successional forests. We found that the presence of mycorrhizal hyphae suppressed soil CO2 fluxes by 17% in early-successional forests, but enhanced CO2...

Plant genotypic diversity effects on soil nematodes vary with trophic level

Jihua Wu, Jun Yan, Youzheng Zhang, Kerri M. Crawford, Xiaoyong Chen & Shuo Yu
At local spatial scales, loss of genetic diversity within species can lead to species loss. Few studies, however, have examined plant genotypic diversity effects across trophic levels. We investigated genotypic diversity effects of Phragmites australis on belowground biomass and soil nematode communities. Our results revealed belowground plant biomass and nematode abundance responses to plant genotypic diversity were uncoupled. Decreasing plant genotypic diversity decreased the abundance of lower, but not higher trophic level nematodes. Low plant...

Island area, not isolation, drives taxonomic, phylogenetic and functional diversity of ants on land-bridge islands

Yuhao Zhao, Robert Dunn, Haonan Zhou, Xingfeng Si & Ping Ding
Aim: To explore the impact of island area and isolation on multiple dimensions of ant biodiversity (taxonomic, phylogenetic, and functional diversity) and the underlying processes of community assembly on islands. Location: Thousand Island Lake, Zhejiang, China, created by dam construction in 1959. Taxon: Ants. Methods: We sampled ants on 33 islands, built a species-level phylogenetic tree and measured five morphological traits of all species collected to estimate taxonomic, phylogenetic, and functional diversity. We used multiple...

Back to the brink: phylogeography and demographic history of the endangered Torreya jackii

Xin Tong, Jian-Hui Li & Xiao-Yong Chen
Both natural and anthropogenic factors can negatively affect species demography and even lead to species extinction, but their relative importance in driving species rarity remains poorly understood. To this end, we investigated the phylogeography and demographic history of the endemic endangered conifer species Torreya jackii. We collected samples from all the 13 extant wild populations, and analyzed the genetic variation using 8 nuclear microsatellites and 4 chloroplast and 1 mitochondrial DNA fragments. Low genetic and...
