Litter decomposition and nutrient release from monospecific and mixed litters: comparisons of litter quality, fauna and decomposition sites effects

Kai Yang, Jiaojun Zhu, Weiwei Zhang, Qian Zhang, Deliang Lu, Yakun Zhang, Xiao Zheng, Shuang Xu & G. Geoff Wang
Litter decomposition and nutrient release are key processes for soil C and nutrient cycling. However, the relative importance of the effects of litter quality, fauna and decomposition sites on litter decomposition remains poorly understood. Moreover, the macronutrient and micronutrient (C, N, P, K, Ca, Mg, Mn, Cu and Zn) release in the decomposition process are even less well-known. In this study, we performed 5040 litterbag samplings of monospecific (Larix gmelinii, Acer mono, Quercus mongolica, and...

Altitudinal dispersal process drives community assembly of montane small mammals

Zhixin Wen, Zhixin Wen, Feijo Anderson, Jinzhao Ke, Xingcheng He, Jilong Cheng, Deyan Ge, Tian Tian, Lin Xia, Yongjie Wu, Jianghong Ran & Qisen Yang
Montane small mammals are subjected to strong forces of dispersal limitation and habitat filtering that mainly operate on their community structures along the altitudinal direction. However, so far little is known about the relative contributions of dispersal and niche processes to their community assembly. By applying the newly-proposed PER-SIMPER/DNCI (dispersal–niche continuum index) framework to small mammal occurrence data collected from 21 extensive altitudinal gradients, we quantitatively assess the relative importance of dispersal and niche processes...

15N recovery under ambient and deepened snow treatments

Lingli Liu
Seasonal differences in plant and microbial nitrogen (N) acquisition are believed to be a major mechanism that maximizes ecosystem N retention. There is also a concern that climate change may interrupt the delicate balance in N allocation between plants and microbes. Yet, convincing experimental evidence is still lacking. Using a 15N tracer, we assessed how deepened snow affects the temporal coupling between plant and microbial N utilization in a temperate Mongolian grassland. We found that...

Data from: Plant diversity improves resistance of plant biomass and soil microbial communities to drought

Yan Li, Jiang Wang, Congcong Shen, Jichen Wang, Brajesh K. Singh & Yuan Ge
1. Biodiversity is known to affect ecosystem resistance and have implications for the maintenance of ecosystem functions and services under climate change. Compared to numbers of studies focusing on aboveground vegetation, the response of belowground communities to abiotic stresses along plant diversity gradients is often ignored and is considered an important knowledge gap in ecosystem ecology. Here we conducted an integrative research to evaluate the resistance of plant biomass, and soil microbial communities and associated...

Cryptic species in a colorful genus: integrative taxonomy of the bush robins (Aves, Muscicapidae, Tarsiger) suggests two overlooked species

Yang Liu, Chentao Wei, George Sangster, Urban Olsson, Pamela Rasmussen, Lars Svensson, Cheng-Te Yao, Geoff Carey, Paul Leader, Ruiying Zhang, Guoling Chen, Gang Song, Fumin Lei, David Wilcove & Per Alström
Several cryptic avian species have been validated by recent integrative taxonomic efforts in the Sino-Himalayan mountains, indicating that avian diversity in this global biodiversity hotspot may be underestimated. In the present study,we investigated species limits in the genus Tarsiger, the bush robins, a group of montane forest specialists with high species richness in the Sino-Himalayan region. Based on comprehensive sampling of all 11 subspecies of the six currently recognized species, we applied an integrative taxonomic...

A rodent herbivore reduces its predation risk through ecosystem engineering

Zhiwei Zhong, Guoliang Li, Dirk Sanders, Deli Wang, Robert Holt & Zhibin Zhang
Predator-prey interactions are ubiquitous and powerful forces structuring ecological communities [1, 2, 3]. Habitat complexity has been shown to be particularly important in regulating the strength of predator-prey interactions [4, 5]. It is now relatively well known that changes in habitat structure can alter the patterns and efficacy of predatory and anti-predatory behaviors of interacting predators and prey [3, 4, 6]. Nevertheless, little is known about the consequences of engineering activity by species on their...

Data from: Opposite effects of nutrient enrichment and an invasive snail on the growth of invasive and native macrophytes

Yimin Yan, Ayub Oduor, Feng Li, Yonghong Xie & Yanjie Liu
Many ecosystems are now co-invaded by alien plant and herbivore species. The evolutionary naivety of native plants to alien herbivores can make the plants more susceptible to detrimental effects of herbivory than co-occurring invasive plants, in accordance with the apparent competition hypothesis. Moreover, the invasional meltdown hypothesis predicts that in multiply invaded ecosystems, invasive species can facilitate each other’s impacts on native communities. Although there is growing empirical support for these hypotheses, facilitative interactions between...

Feasible carbon-trade model for low-carbon density ecosystem

Xueyan Zhang & Xin Ma
China has set a carbon-neutrality target for 2060; carbon sinks are vital tools to meet this target. China is leading the effort in greening the world through the restoration of low-carbon density ecosystems (LCDEs). The potential carbon sinks of LCDEs provide opportunities for carbon trading projects that make cash benefits accessible to the owners, thereby incentivizing ecosystem restoration. Unfortunately, carbon trading in LCDEs has, to date, been unsuccessful in China. Therefore, it is important to...

Reassessment of Chirita umbrophila (Gesneriaceae) based on molecular and morphological evidence

Peng-Wei Li, James F. Smith, Debabrata Maity, Xi-Zuo Shi & Li-Hua Yang
Chirita umbrophila C.Y.Wu ex H.W.Li is a species endemic to Yunnan, China, and its exact systematic position remains a mystery since it was treated as a species with uncertain generic affiliation in the taxonomic revision of Chirita Buch.-Ham. ex Don in 1985. In the present study, the phylogenetic relationships between C. umbrophila and its allied species were inferred using two nuclear ribosomal DNA regions (ETS and ITS) and three chloroplast regions (rpl16, rps16, and trnL-F)....

Data from: Herbivory may mediate the effects of nutrients on the dominance of alien plants

Yanjun Li, Yingzhi Gao, Mark Van Kleunen & Yanjie Liu
1. Numerous studies have highlighted the role of nutrient availability and fluctuations therein for invasion success of alien plants. Others also highlighted the role of herbivores in invasion success. However, how herbivory and the level and fluctuations in nutrient availability interact in driving alien plant invasion into native communities remains largely unexplored. 2. We grew eight invasive alien species as target species in pot-mesocosms with five different synthetic native communities in a three-factorial design with...

A dataset of sulfur content and density of vegetation on the Tibetan Plateau

Wenzong Zhao & Nianpeng He
As an important part of China's terrestrial ecosystem, the variation and distribution of sulfur in the vegetation of the Tibetan Plateau (TP) will have a profound impact on the national and even global sulfur cycle. We collected and sorted out the field survey and test data of the research group from 2019 to 2020. This dataset encompasses forest, grassland, shrubland, desert and other major ecosystem types, including the average sulfur content, density and storage data...

Hydrothermal conditions determine soil potential net N mineralization rates in arid and semi-arid grasslands

Shuya Hu, Changhui Wang, Anita Risch, Yuan Liu, Yang Li, Lei Li, Xiaohui Xu, Nianpeng He, Xingguo Han & Jianhui Huang
Soil net nitrogen (N) mineralization is a key biogeochemical process influencing plant available N and net primary productivity (NPP) in terrestrial ecosystems. However, the spatial variations and controlling factors of soil net N mineralization (RPNM) in arid and semi-arid grasslands are less studied and unclear. In this study, we investigated the soil RPNM by performing a laboratory incubation experiment. Soil samples were collected from 30 sites in three east-west transects on the Inner Mongolia Plateau...

Tropical–temperate comparisons in insect seed predation vary between study levels and years

Kai Zhang, Wenlan Wu, Xiaoxue Wang, Tao Zhao, Wenfu Zhang, Shuai Fang & Yu Xu
The biotic interaction hypothesis, which states the species interaction becomes stronger in the tropics, is deeply rooted in classic ecological literature and widely accepted to contribute to the latitudinal gradients of biodiversity. Tests in latitudinal insect-plant interaction have emphasized leaf-eating insects on a single or a few plant species rather than within an entire community and mixed accumulating evidence, leaving the biotic interaction hypothesis disputed. We aimed to test the hypothesis by quantifying seed predation...

Scale-dependent species-area relationship: niche-based versus stochastic processes in a typical subtropical forest

Haibao Ren, Jens-Christian Svenning, Xiangcheng Mi, James A. Lutz, Jinxing Zhou & Keping Ma
Determining the patterns and drivers of the small-scale species-area relationship (SAR) is crucial for improving our understanding of community assembly and biodiversity patterns. Niche-based and stochastic processes are two principal categories of mechanisms potentially driving SARs. However, their relative importance has rarely been quantified rigorously owing to scale-dependence and the simplified niche volumes often used. In a fully mapped, 24-ha plot of a typical subtropical forest, we built the SARs and well-defined niche-hyper-volumes of a...

Supplemental files for: A consensus view of the proteome of the last universal common ancestor

Aaron Goldman, Andrew Crapitto, Amy Campbell & AJ Harris
The availability of genomic and proteomic data from across the tree of life has made it possible to infer features of the genome and proteome of the last universal common ancestor of life (LUCA). A number of studies have done so, all using a unique set of methods and bioinformatics databases. Here, we compare predictions across eight such studies and measure both their agreement with one another and with the consensus predictions among them. We...

Changes in temperature alter competitive interactions and overall structure of fig wasp communities

Khin Me Me Aung, Huan-Huan Chen, Simon Segar, Yan-Qiong Peng & Cong Liu
1. Organisms exist within ecological networks, connected through interactions such as parasitism, predation and mutualism which can modify their abundance and distribution within habitat patches. Differential species responses make it hard to predict the influence of climate change at the community scale. Understanding the interplay between climate and biotic interactions can improve our predictions of how ecosystems will respond to current global warming. 2. We aim to understand how climate affects the multi-trophic biotic interactions...

WorldClim, elevation and distribution data for all palms from: The ecology of palm genomes: Repeat-associated genome size expansion is constrained by aridity

Rowan Schley, Jaume Pellicer, Xue-Jun Ge, Craig Barrett, Sidonie Bellot, Maite Guignard, Petr Novak, Donald Fraser, William Baker, Steven Dodsworth, Jiri Macas, Andrew Leitch & Ilia Leitch
Genome size varies 2,400-fold across plants, influencing their evolution through changes in cell size and cell division rates which impact plants’ environmental stress tolerance. Repetitive element expansion explains much genome size diversity, and the processes structuring repeat ‘communities’ are analogous to those structuring ecological communities. However, which environmental stressors influence repeat community dynamics has not yet been examined from an ecological perspective. We measured genome size and leveraged climatic data for 91% of genera within...

Data from: Amphibious mudskipper populations are genetically connected along coastlines, but differentiated across water

Joel Corush, Benjamin Fitzpatrick, Todd Pierson, Jen-Chieh Shiao, Yukitoshi Katayama & Jie Zhang
Aim: Many mudskippers in the family Gobiidae are obligately amphibious, requiring both aquatic and terrestrial portions of their life cycle. The terrestrial phase involves restrictions to mudflat habitats during breeding, when adults build burrows in the mud to lay eggs. The effects of this restricted out-of-water phase might be reflected in the population structure of the species. However, dispersal during the aquatic larval phase could connect distant populations. We examine one such mudskipper, Periophthalmus modestus,...

Variations and controlling factors of soil denitrification rate

Zhaolei Li, Ze Tang, Zhaopeng Song, Weinan Chen, Dashuan Tian, Shiming Tang, Xiaoyue Wang, Jinsong Wang, Wenjie Liu, Yi Wang, Jie Li, Lifen Jiang, Yiqi Luo & Shuli Niu
The denitrification process profoundly affects soil nitrogen (N) availability and generates its byproduct, nitrous oxide, as a potent greenhouse gas. There are large uncertainties in predicting global denitrification because its controlling factors remain elusive. In this study, we compiled 4301 observations of denitrification rates across a variety of terrestrial ecosystems from 214 papers published in the literature. The averaged denitrification rate was 3516.3 ± 91.1 µg N kg−1 soil day−1. The highest denitrification rate was...

From: Soil fauna accelerate litter mixture decomposition globally, especially in dry environments

Denis Njoroge, Si-Chong Chen, Juan Zuo, Gbadamassi Dossa & Hans Cornelissen
More than half of net primary production in terrestrial ecosystems returns to the soil through leaf litter fall and decomposition. In terrestrial ecosystems, litter constitutes a mixture of mainly senescent foliage from multiple species. Yet, the effect of litter mixing on litter decomposition rate remains ambiguous. Quantification of the soil fauna contribution and inclusion of their interaction with litter could remove the prevailing ambiguity, as soil fauna might influence the direction and magnitude of litter...

Phosphorus supply increases nitrogen transformation rates and retention in soil: a global meta-analysis

Ruzhen Wang, Bahareh Bicharanloo, Enqing Hou & Yong Jiang
Interactions between nitrogen (N) and phosphorus (P) are important for plant growth and ecosystem carbon (C) sequestration. While effects of N supply on P dynamics have been much studied, much less is known about the opposite (P-effect on N). We conducted a meta-analysis by compiling a total of 1734 individual experimental observations from 116 peer-reviewed publications to assess P-addition effects on soil N dynamics. Globally, P additions increased the soil total N (TN) pool, potentially...

Data from: Extensive sympatry and frequent hybridization of ecologically divergent aquatic plants on the Qinghai-Tibetan Plateau

Zhigang Wu, Zhong Wang, Dong Xie, Juan Zhang, Pengsen Cai, Xing Li, Xinwei Xu, Tao Li & Jindong Zhao
Hybridization has fascinated biologists in recent centuries for its evolutionary importance, especially in plants. Hybrid zones are commonly located in regions across environmental gradients due to more opportunities to contact and ecological heterogeneity. For aquatic taxa, intrazonal character makes broad overlapping regions in intermediate environments between related species. However, we have limited information on the hybridization pattern of aquatic taxa in alpines, especially submerged macrophytes. In this study, we aimed to test the hypotheses that...

Phylogenomics and biogeography of Torreya (Taxaceae) – Integrating data from three organelle genomes, morphology, and fossils and a practical method for reducing missing data from RAD-seq

Wenbin Zhou, AJ Harris &
Restriction site-associated DNA sequencing (RAD-seq) enables obtaining thousands of genetic markers for phylogenomic studies. However, RAD-seq data are subject to allele dropout (ADO) due to polymorphisms at enzyme cutting sites. We developed a new pipeline, RADADOR, to mitigate the ADO in outgroups by recovering missing loci from previously published transcriptomes in our study of a gymnosperm genus Torreya. Using the supplemented RAD-seq data in combination with plastome and mitochondrial gene sequences, morphology, and fossil records,...

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...

Hemiboea shimentaiensis (Gesneriaceae), a new species from northern Guangdong, China

Shenyu Miao, Guoxin Guo, Keyuan Dai, Jinhai Xiao, Yuanqiu Li & Tao Chen
Hemiboea shimentaiensis S. Y. Miao, Y. Q. Li & T. Chen (Gesneriaceae), a new species from northern Guangdong, China, is described and illustrated. It is most similar to H. gamosepala, H. rubribracteata and H. malipoensis in the nearly white corolla, which appears in a few species of Hemiboea, and nearly glabrous inner base of the corolla tube. It can be easily distinguished from the latter three species by the stoloniferous habit, distinct silvery veins, glabrous...
