Data from: A global meta-analyses of the response of multi-taxa diversity to grazing intensity in grasslands

Chao Wang & Yujia Tang
Livestock grazing is an important component and driver of biodiversity in grassland ecosystems. While numerous studies and a few meta-analyses had been conducted on the response of single taxon diversity to grazing in grasslands, a synthesis of how multi-taxa diversity is affected has been largely missing, especially reflecting its changes along a grazing intensity gradient. We performed a comprehensive meta-analyses of 116 published studies on the species richness (SR) and Shannon-Wiener index (H’) of plants,...

Data from: Ovipositor and mouthparts in a fossil insect support a novel ecological role for early orthopterans in 300 million years old forests

Lu Chen, Alexander Blanke, Jun-Jie Gu, Qiang Yang, Dong Ren & Olivier Béthoux
A high portion of the earliest known, Pennsylvanian, insect fauna is composed of the so-called ‘lobeattid insects’, which systematic affinities and role as foliage feeders remain debated. We investigated hundreds of samples of a new lobeattid species from the Xiaheyan locality using a combination of photographic techniques, including Reflectance Transforming Imaging, and geometric morphometrics, to document its morphology, and infer its phylogenetic position and ecological role. Ctenoptilus frequens sp. nov. possessed a sword-shaped ovipositor whose...

Micro-CT data from: Maternal care in mid-Cretaceous lagonomegopid spiders

Xiangbo Guo, Paul Selden & Dong Ren
This dataset contains the raw Micro-CT data and a 3D CT reconstruction of a piece of Burmese amber CNU009432 from "Guo, X., Selden, P. and Ren, D. (2021) Maternal care in mid-Cretaceous lagonomegopid spiders. Proc. R. Soc. B.". These data shows the maternal care behaviour of an adult female lagonomegopid spider guarding her egg sac. Maternal care benefits the survival and fitness of offspring often at a cost to the mother's future reproduction and has...

Data from: Nutrient addition affects scaling relationship of leaf nitrogen to phosphorus in Arabidopsis thaliana

Zhengbing Yan, Xiuping Li, Di Tian, Wenxuan Han, Xinghui Hou, Haihua Shen, Yalong Guo & Jingyun Fang
1. Ambient nutrient changes influence the coupling of nitrogen (N) and phosphorus (P) in terrestrial ecosystems, but whether it could alter the scaling relationship of plant leaf N to P concentrations remains unclear. 2. Here we conducted experimental manipulations using Arabidopsis thaliana, with five levels of N and P additions and nine repeated experiments, and then evaluated the changes in the scaling relationship of leaf N to P concentrations under nutrient additions. 3. Overall, leaf...

Data from: Cretaceous lophocoronids with short proboscis and retractable female genitalia provide the earliest evidence for their feeding and oviposition habits

Weiting Zhang, Chungkun Shih, Michael Engel & Dong Ren
We describe two new species of Lophocoronidae: Acanthocorona hedida Zhang, Shih and Engel sp. n. and Acanthocorona venulosa Zhang, Shih and Engel sp. n., and an undetermined specimen from mid-Cretaceous Kachin amber. Phylogenetic analysis of basal lepidopteran lineages, including three extinct families, was undertaken. The analysis supported monophyly of Glossata although internal relationships remain controversial. Acanthocorona and Lophocorona form a monophyletic group. It is likely that short and simply structured proboscides of Acanthocorona were used...

Data from: A new tealliocaridid crustacean from the Late Carboniferous of North China and its biogeographic implications

Qiang Yang, Pierre Gueriau, Sylvain Charbonnier, Dong Ren, Olivier Béthoux & Sylvain Charbonner
A new tealliocaridid eumalacostracan is described from the Late Carboniferous Tupo Formation (Ningxia, China). Laevitealliocaris xiaheyanensis gen. et sp. nov. is represented by a single specimen, characterised by the possession of a short rostrum without dorsal spine, a short postcervical carina and only one weak branchial carina, both tuberculate, and a short sixth pleonal somite. This is the first unequivocal record of tealliocaridids outside Euramerica, which occurrence along the eastern inner margin of the Palaeotethys...

Data from: A new Cretaceous genus of xyelydid sawfly illuminating nygmata evolution in Hymenoptera

Wang Mei, Alexandr P. Rasnitsyn, Chungkun Shih & Dong Ren
Background: Nygmata are prominent glandular structures on the wings of insects. They have been documented in some extant insects, including several families of Neuroptera and Mecoptera, the majority of Trichoptera, and a few of the hymenopteran Symphyta. However, because nygmata are rarely preserved in compression fossils, their early development and evolution are still enigmatic. For example, the only documented nygmata in the Hymenoptera are on the forewings of the Triassic xyelids Asioxyela paurura and Madygenius...

Data from: Responses of plant phenology to nitrogen addition: a meta-analysis

Chao Wang & Yujia Tang
Phenology is one of the most sensitive plant processes in response to global change. Anthropogenic activities have considerably increased nitrogen (N) deposition, which significantly affects plant phenology. Although numerous individual studies have been conducted, a comprehensive understanding of how plant phenology responds to external N inputs remains elusive. We therefore conducted a meta-analysis of 117 species responses to N addition to examine effects on phenology in terrestrial ecosystems, and we assessed variations in their responses...

Identification of species by combining molecular and morphological data using convolutional neural networks

Ai-Bing Zhang, Bing Yang, Zhenxin Zhang, Cai-Qing Yang, Ying Wang, Michael C. Orr & Hongbin Wang
Integrative taxonomy is central to modern taxonomy and systematic biology, including behavior, niche preference, distribution, morphological analysis, and DNA barcoding. However, decades of use demonstrate that these methods can face challenges when used in isolation, for instance, potential misidentifications due to phenotypic plasticity for morphological methods, and incorrect identifications because of introgression, incomplete lineage sorting, and horizontal gene transfer for DNA barcoding. Although researchers have advocated the use of integrative taxonomy, few detailed algorithms have...

Data from: The divergence and positive selection of the plant-specific BURP-containing protein family

Lihui Wang, Ningning Wu, Yan Zhu, Wanlu Song, Xin Zhao, Yaxuan Li & Yingkao Hu
BURP domain-containing proteins belong to a plant-specific protein family and have diverse roles in plant development and stress responses. However, our understanding about the genetic divergence patterns and evolutionary rates of these proteins remain inadequate. In this study, 15 plant genomes were explored to elucidate the genetic origins, divergence, and functions of these proteins. One hundred and twenty-five BURP protein-encoding genes were identified from four main plant lineages, including 13 higher plant species. The absence...

Data from: Determination of sulfonamides in milk by capillary electrophoresis with PEG@MoS2 as a dispersive solid-phase extraction sorbent

Jianxin An, Xuan Wang, Meiting Ming, Jian Li & Nengsheng Ye
A synthetic polyethylene glycol-molybdenum disulfide (PEG@MoS2) composite was prepared using a simple method, and the application of this material in dispersive solid-phase extraction (DSPE) was investigated for the enrichment of eight sulfonamides (SAs) in milk samples. The composite was characterized by energy dispersive spectroscopy, scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy and Brunner-Emmett-Teller measurements. The results showed that the MoS2 synthesized in the presence of PEG has the advantage of a larger...

Data from: Anterior insular cortex plays a critical role in interoceptive attention

Xingchao Wang, Qiong Wu, Laura Egan, Xiaosi Gu, Pinan Liu, Hong Gu, Yihong Yang, Jing Luo, Yanhong Wu, Zhixian Gao & Jin Fan
Accumulating evidence indicates that the anterior insular cortex (AIC) mediates interoceptive attention, which refers to attention towards physiological signals arising from the body. However, the necessity of the AIC in this process has not been demonstrated. Using a novel task that directs attention toward breathing rhythm, we assessed the involvement of the AIC in interoceptive attention in healthy participants using functional magnetic resonance imaging and examined the necessity of the AIC in interoceptive attention in...

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....

Data from: The first flea with fully distended abdomen from the Early Cretaceous of China

Taiping Gao, Chungkun Shih, Alexandr P. Rasnitsyn, Xing Xu, Shuo Wang & Dong Ren
Background: Fleas, the most notorious insect ectoparasites of human, dogs, cats, birds, etc., have recently been traced to its basal and primitive ancestors during the Middle Jurassic. Compared with extant fleas, these large basal fleas have many different features. Although several fossil species with transitional morphologies filled the evolutionary blank, the early evolution of these ectoparasites is still poorly known. Results: Here we report a new flea with transitional morphology, Pseudopulex tanlan sp. nov., assigned...

Regional assemblages shaped by historical and contemporary factors: evidence from a species-rich insect group

Mengdi Hao, Qian Jin, Guanliang Meng, Caiqing Yang, Shenzhou Yang, Zhiyong Shi, Min Tang, Shanlin Liu, Yinan Li, Dan Zhang, Xu Su, Chungkun Shih, Yiran Sun, Xin Zhou & Ai-Bing Zhang
Understanding the complex diversity patterns is one of the main aims of community ecology. It is important to take both historical and contemporary factors into account in investigating the potential roles in assembling diversity patterns. Here, We compared diversity patterns of two moth assemblages sampled from Taihang and Yanshan mountains in Northern China and performed ancestral range reconstructions using the Multi-State-Speciation and Extinction model to track the origins of these patterns. We subsequently estimate diversification...

Data from: Using full-length metabarcoding and DNA barcoding to infer community assembly for speciose taxonomic groups: a case study

Mengdi Hao, Qian Jin, Guanliang Meng, Caiqing Yang, Shenzhou Yang, Zhiyong Shi, Min Tang, Shanlin Liu, Yinan Li, Jing Li, Dan Zhang, Xu Su, Chungkun Shih, Yiran Sun, John James Wilson, Xin Zhou & Aibing Zhang
How insect communities are assembled in nature remains largely unknown. In particular, whether habitat filtering or competition serves as the main mechanism in forming insect communities is rarely subject to an in-depth investigation. One bottleneck lies in the difficulty of species identification when dealing with a large number of diverse insects. However, High-Throughput Sequencing (HTS) technology coupled with classic DNA barcoding offers a great opportunity to infer community assembly for this speciose group. In this...

Data from: Variations of mesozoic feathers: insights from the morphogenesis of extant feather rachises

Shuo Wang, Wei-Ling Chang, Qiyue Zhang, Menglu Ma, Feng Yang, De Zhuo, Harn I-Chen Hans, Rui Yang, Ping Wu, Michael Bruce Habib, Wen-Tau Juan & Cheng-Ming Chuong
The rachises of extant feathers, composed of dense cortex and spongy internal medulla, are flexible and light, yet stiff enough to withstand the load required for flight, among other functions. Incomplete knowledge of early feathers prevents a full understanding of how cylindrical rachises have evolved. Bizarre feathers with unusually wide and flattened rachises, known as “rachis-dominated feathers” (RDFs) have been observed in fossil non-avian and avian theropods. Newly discovered RDFs embedded in early Late Cretaceous...

Kathleen R. Stoof-Leichsenring, Sisi Liu, Weihan Jia, Kai Li, Luidmila A. Pestryakova, Steffen Mischke, Xianyong Cao, Xinqui Liu, Jian Ni, Stefan Neuhaus & Ulrike Herzschuh
Here we provide a large dataset on genetic plant diversity retrieved from surface sedimentary DNA (sedDNA) of lakes from Siberia and China spanning over a large environmental gradient. Our dataset encompasses sedDNA sequence data of 244 surface lake sediments and 3 soil samples originating from Siberia and Chinese lakes. We used a PCR-based metabarcoding approach combined with Next-Generation Sequencing to assess the modern and local plant diversity in and around the analysed lake localities. As...

Data from: Selection signature analysis reveals genes associated with tail type in Chinese indigenous sheep

Zehu Yuan, Enming Liu, Z. Liu, J. W. Kijas, Caiye Zhu, Shijin Hu, Xiaomeng Ma, Li Zhang, Lixin Du, Huihua Wang & Caihong Wei
Fat-tailed sheep have commercial value because consumers prefer high-protein and low-fat food and producers care about feed conversion rate. However, fat-tailed sheep still have some scientific significance, as the fat tail is commonly regarded as a characteristic of environmental adaptability. Finding the candidate genes associated with fat tail formation is essential for breeding and conservation. To identify these candidate genes, we applied FST and hapFLK approaches in fat- and thin-tailed sheep with available 50K SNP...

Data from: A fuzzy-set-theory-based approach to analyze species membership in DNA barcoding

Ai-Bing Zhang, Christoph Muster, Hong-Bing Liang, Chao-Dong Zhu, Ross Crozier, Ping Wan, Jie Feng & Robert D Ward
Reliable assignation of an unknown query sequence to its correct species remains a methodological problem for the growing field of DNA barcoding. While great advances have been achieved recently, species identification from barcodes can still be unreliable if the relevant biodiversity has been insufficiently sampled. We here propose a new notion of species membership for DNA barcoding - fuzzy membership, based on fuzzy set theory - and illustrate its successful application to four real datasets...
