Data from: Tectonic evolution of the Tethyan region created the Eurasian extratropical biodiversity hotspots: tracing Pireneitega spiders' diversification history

Zhe Zhao, Lili Shao, Fengyuan Li, Xiaoqing Zhang & Shuqiang Li
The withdrawal of the Tethys Sea and the formation of the Alpine-Himalayan orogenic belt profoundly impacted the distribution and composition of terrestrial biota in Eurasia. However, studies that have explicitly addressed the potential links between the series of tectonic activities in the Tethyan region and the formation of extratropical biodiversity hotspots in the Alpine-Himalayan belt are rare. The Pireneitega spiders (Agelenidae) are found throughout Eurasia and show high species richness in these hotspots. Thus, using...

Data from: Protection of pepper plants from drought by microbacterium sp. 3J1 by modulation of the plant's glutamine and α-ketoglutarate content: a comparative metabolomics approach

Cristina Garcia Fontana, Juan Ignacio Vílchez & Maximino Manzanera
Desiccation-tolerant plants are able to survive for extended periods of time in the absence of water. The molecular understanding of the mechanisms used by these plants to resist droughts can be of great value for improving drought tolerance in crops. This understanding is especially relevant in an environment that tends to increase the number and intensity of droughts. The combination of certain microorganisms with drought-sensitive plants can improve their tolerance to water scarcity. One of...

Estimating occupancy of Chinese pangolin (Manis pentadactyla) in a protected and non-protected area of Nepal

Sandhya Sharma, Hari Sharma, Chanda Chaulagain, Hem Katuwal & Jerrold Belant
Chinese pangolin is the world’s most heavily trafficked small mammal for luxury food and traditional medicine. Although their populations are declining worldwide, it is difficult to monitor their population status because of its rarity and nocturnal behavior. We used site occupancy (presence/absence) sampling of pangolin sign (i.e. active burrows) in a protected (Gaurishankar Conservation Area) and non-protected area (Ramechhap district) of central Nepal with multiple environmental covariates to understand factors that may influence occupancy of...

Long-term deepened snow cover alters litter layer turnover rate in temperate steppes

Jing Wang, Weixing Liu, Ping Li, Zhou Jia, Meifeng Deng, Sen Yang & Lingli Liu
1. The turnover of litter layer is a biogeochemical process fundamental to carbon and nutrient cycling, influencing seed germination, species coexisting, and carbon storage. Winter snow depth is undergoing increasing trend in Northern China, which has been shown to alter litter decomposition rate of individual species. However, it remains unknown how changes in snow depth affect the turnover rate of the whole litter layer, and whether the responses vary between different steppes. Most current litter...

Trade-off between vegetation type, soil erosion control and surface water in global semi-arid regions: A meta-analysis

Gao-Lin Wu, Yi-Fan Liu, Zeng Cui, Yu Liu, Zhi-Hua Shi, Rui Yin & Paul Kardol
Soil erosion control and water resource protection can closely interact during restoration of terrestrial ecosystems. In semi‐arid ecosystems, an urgent issue is how vegetation restoration can achieve the goal of soil erosion mitigation and water conservation, which in turn, feeds back to ecosystem functioning. We reviewed 78 articles from 22 countries in semi‐arid areas to evaluate the effects of vegetation type (i.e. forest, grassland and scrubland) on runoff and sediment yields across different environmental conditions...

Data from: Cropland connectivity affects genetic divergence of Colorado potato beetle along an invasion front

Fangyuan Yang, Ning Liu, Michael S. Crossley, Pengcheng Wang, Zhuo Ma, Jianjun Guo & Runzhi Zhang
The population genetic structure of invasive species can be strongly affected by environmental and landscape barriers to dispersal. Disentangling the relative contributions of these factors to genetic divergence among invading populations is a fundamental goal of landscape genetics with important implications for invasion management. Here, we relate patterns of genetic divergence in a global invasive agricultural pest, Colorado potato beetle (CPB; Leptinotarsa decemlineata), to environmental and landscape factors along an invasion front in Northwestern China....

Data from: Changes in ecosystem carbon stocks following grazing exclusion in arid and semiarid grasslands

Lingfei Yu, Wenjuan Sun & Yao Huang
Grazing exclusion (GE) is widely considered to be an important strategy for restoring overgrazed grasslands and promoting carbon (C) storage. However, the changes in the components of ecosystem C with GE and their related drivers remain largely unexplored. Here, we investigated the effects of GE on the ecosystem C components (plant and soil C) and their key driving factors through sampling inside and outside 15 grazing exclosures across the Inner Mongolia arid and semiarid grasslands...

Genomic signatures of domestication in Old World camels

Robert Fitak, Elmira Mohandesan, Jukka Corander, Adiya Yadamsuren, Battsetseg Chuluunbat, Omer Abdelhadi, Abdul Raziq, Peter Nagy, Chris Walzer, Bernard Faye & Pamela Burger
Domestication begins with the selection of animals showing less fear of humans. In most domesticates, selection signals for tameness have been superimposed by intensive breeding for economical or other desirable traits. Old World camels, conversely, have maintained high genetic variation and lack these secondary bottlenecks associated with breed development. By re-sequencing multiple genomes from dromedaries, Bactrian camels, and their endangered wild relatives, we show that positive selection for candidate genes underlying traits collectively referred to...

Evidence for Elton’s diversity-invasibility hypothesis from belowground

Zhijie Zhang, Yanjie Liu, Caroline Brunel & Mark Van Kleunen
Sixty year ago, Charles Elton posed that species-rich communities should be more resistant to biological invasion. However, still little is known about which processes could drive the diversity-invasibility relationship. Here we examined whether soil-microbes-mediated apparent competition on alien invaders is more negative when the soil originates from multiple native species. We trained soils with five individually grown native species, and used amplicon sequencing to analyze the resulting bacterial and fungal soil communities. We mixed the...

Long-term empirical evidence, early warning signals, and multiple drivers of regime shifts in a lake ecosystem

Haojie Su, Rong Wang, Yuhao Feng, Yanling Li, Yun Li, Jun Chen, Chi Xu, Shaopeng Wang, Jingyun Fang & Ping Xie
1. Catastrophic regime shifts in various ecosystems are increasing with the intensification of anthropogenic pressures. Understanding and predicting critical transitions are thus a key challenge in ecology. Previous studies have mainly focused on single environmental drivers (e.g., eutrophication) and early warning signals (EWSs) prior to population collapse. However, how multiple environmental stressors interact to shape ecological behaviour and whether EWSs were detectable prior to the recovery process in lake ecosystems are largely unknown. 2. We...

Nitrogen economy of alpine plants on the north Tibetan Plateau: nitrogen conservation by resorption rather than open sources through biological symbiotic fixation

Ning Zong
Nitrogen (N) is one of the most important factors limiting plant productivity, and N fixation by legume species is an important source of N input into ecosystems. Meanwhile, N resorption from senescent plant tissues conserves nutrients taken up in the current season, which may alleviate ecosystem N limitation. N fixation was assessed by the 15N dilution technique in four types of alpine grasslands along the precipitation and soil nutrient gradients. The N resorption efficiency (NRE)...

Phylogenomics of white-eyes, a ‘great speciator,’ reveals Indonesian archipelago as the center of lineage diversity

Chyi Yin Gwee, Kritika Garg, Balaji Chattopadhyay, Keren Sadanandan, Dewi Prawiradilaga, Martin Irestedt, Fu-Min Lei, Luke Bloch, Jessica Lee, Mohammad Irham, Tri Haryoko, Malcolm Soh, Kelvin Peh, Karen Rowe, Teuku Ferasyi, Shaoyuan Wu, Guinevere Wogan, Rauri Bowie & Frank Rheindt
Archipelagoes serve as important ‘natural laboratories’ which facilitate the study of island radiations and contribute to the understanding of evolutionary processes. The white-eye genus Zosterops is a classical example of a ‘great speciator’, comprising c. 100 species from across the Old World, most of them insular. We achieved an extensive geographic DNA sampling of Zosterops by using historical specimens and recently collected samples. Using over 700 genome-wide loci in conjunction with coalescent species tree methods...

Data from: Genomic evidence of prevalent hybridization throughout the evolutionary history of the fig-wasp pollination mutualism

Gang Wang, Xingtan Zhang, Edward Herre, Charles Cannon, Doyle McKey, Carlos Machado, Wen-Bin Yu, Michael Arnold, Rodrigo Pereira, Ray Ming, Yi-Fei Liu, Yibin Wang, Dongna Ma & Jin Chen
Ficus (figs) and their agaonid wasp pollinators present an ecologically important mutualism that also provides a rich comparative system for studying functional co-diversification throughout its coevolutionary history (~75 million years). We obtained entire nuclear, mitochondrial, and chloroplast genomes for 15 species representing all major clades of Ficus. Multiple analyses of these genomic data suggest that hybridization events have occurred throughout Ficus evolutionary history. Furthermore, cophylogenetic reconciliation analyses detect significant incongruence among all nuclear, chloroplast, and...

Population genetics and forensic efficiency of 30 InDel markers in four Chinese ethnic groups residing in Sichuan

Fei Wang, Guanglin He, Zheng Wang, Mengge Wang, Jing Liu, Xing Zou, Shouyu Wang, Mengyuan Song, Ziwei Ye, Mingkun Xie & Yiping Hou
Sichuan Province is located at the transitional junction regions of the Qinghai-Tibet Plateau and the low-altitude plains. It also serves as the corridor of Sino-Tibetan-speaking population migration and expansion since neolithic expansion of Proto-Tibeto-Burman populations from Middle/Upper Yellow River during Majiayao period (3300–2000 BC). However, the population structure and the corresponding genetic diversity of forensic-related markers in this region remain unclear. Thus, we genotyped 30 insertion-deletion (InDel) markers in 444 samples from four ethnic groups...

Data from: Brachial supporting structure of Spiriferida (Brachiopoda)

Zhiwei Yuan, Wen Guo, Dan Lü & Yuanlin Sun
The filter-feeding organ of some extinct brachiopods is supported by a skeletal apparatus called the brachidium. Although relatively well-studied in Atrypida and Athyridida, the brachidial morphology is usually neglected in Spiriferida. To investigate the variations of brachidial morphology in Spiriferida, 65 species belonging to eight superfamilies were analyzed. Based on the presence/absence of the jugal processes and normal/modified primary lamellae of the spiralia, four types of brachidium are recognized. Type-I (with jugal processes) and Type-II...

Mutant sequences of OsGSTU17

Xue Yang, Zhihai Wu & Jie Gao
Glutathione S-transferases (GSTs) are a family of phase II detoxification enzymes whose main function is to improve plant resistance to stresses. To understand the structural effects of tau class GSTs on their function, using OsGSTU17 as an example, we predicted three pairs of residues involving in the interactions between its domains and linker region, and obtained the corresponding single mutation sequences through site-directed mutating Arg20, Glu74 and Asp77 which involved the hydrogen bonds and salt...

A three year trans-generational plasticity in life history traits

Zhaoren Wang
1. Environmental conditions of maternal plants influence adaptive strategies of their progeny via the seed phenotype. Although traditionally, studies have explained patterns of reproduction traits in response to stresses, such as the changes in seed mass and seed germinability under different maternal conditions. However, it is still unclear how maternal effects affect progeny dispersal and germination strategy or how many generations plasticity persists. 2. Plants from diaspore types A and C of the diaspore-heteromorphic annual...

Data from: Parallel evolution of bower-building behavior in two groups of bowerbirds suggested by phylogenomics

Per G. P. Ericson, Martin Irestedt, Johan A. A. Nylander, Les Christidis, Leo Joseph & Yanhua Qu
The bowerbirds in New Guinea and Australia include species that build the largest and perhaps most elaborately decorated constructions outside of humans. The males use these courtship bowers, along with their displays, to attract females. In these species, the mating system is polygynous and the females alone incubate and feed the nestlings. The bowerbirds also include 10 species of the socially monogamous catbirds in which the male participates in most aspects of raising the young....

Soil dissolved organic carbon in terrestrial ecosystems: global budget, spatial distribution and controls

Xiaofeng Xu, Ziyu Guo, Yihui Wang & Zhongmei Wan
Aims: Soil dissolved organic carbon (DOC) is a primary form of labile carbon in terrestrial ecosystems and therefore plays a vital role in soil carbon cycling. This study aims to quantify the budgets of soil DOC at biome- and global levels and to examine the variations in soil DOC and their environmental controls. Location: Global Time period: 1981 - 2019 Method: We compiled a global dataset and analyzed the concentration and distribution of DOC across...

The global critical frequency foEs data derived from the FORMOSAT-3/COSMIC S4max for the period 2006 to 2014

Bingkun Yu, Christopher Scott, Xianghui Xue, Xinan Yue & Xiankang Dou
The ionospheric sporadic E (Es) layer has a significant impact on the Global Positioning System (GPS)/Global Navigation Satellite System (GNSS) signals. These influences on the GPS/GNSS signals can also be used to study the occurrence and characteristics of the Es layer on a global scale. In this paper, 5.8 million radio occultation (RO) profiles from the FORMOSAT-3/COSMIC satellite mission and ground-based observations of Es layers recorded by 25 ionospheric monitoring stations and held at the...

Activation of astrocytes in hippocampus decreases fear memory through adenosine A1 receptors

Yan-Qin Yu, Yulan Li, Lixuan Li, Jintao Wu, Zhenggang Zhu, Xiang Feng, Liming Qin, Yuwei Zhu, Zilong Qiu & Shumin Duan
Astrocytes respond to and regulate neuronal activity, yet their role in mammalian behavior remains incompletely understood. Especially unclear is whether, and if so how, astrocyte activity regulates contextual fear memory, the dysregulation of which leads to pathological fear-related disorders. We generated GFAP-ChR2-EYFP rats to allow the specific activation of astrocytes in vivo by optogenetics. We found that after memory acquisition within a temporal window, astrocyte activation disrupted memory consolidation and persistently decreased contextual but not...

Data from: Native drivers of fish life history traits are lost during the invasion process

Rodolphe Gozlan, Eva Zahorskae, Emira CHERIF, Takashi Asaeda, Robert Britton, Cha-Ho Chang, To Hong, Rafael Miranda, Jiri Musil, Meta Povz, Serhan Tarkan, Elena Tricarico, Tricia Trichkova, Hugo Verreycken, Andrej Weiperth, Andrej Witkowski, Lluis Zamora, Irene Zweimuller, Ya-Hui Zhao, Hamid Esmaeili & Marine Combe
Rapid adaptation to global change can counter vulnerability of species to population declines and extinction. Theoretically, under such circumstances both genetic variation and phenotypic plasticity can maintain population fitness, but empirical support for this is currently limited. Here, we aim to characterise the role of environmental and genetic diversity, and their prior evolutionary history (via haplogroup profiles) in shaping patterns of life history traits during biological invasion. Data were derived from both genetic and life...

Interactive effects of rising temperature and nutrient enrichment on aquatic plant growth, stoichiometry, and palatability

Peiyu Zhang, Ayumi Kuramae, Casper Van Leeuwen, Mandy Velthuis, Ellen Van Donk, Jun Xu & Elisabeth Bakker
The abundance and stoichiometry of aquatic plants are crucial for nutrient cycling and energy transfer in aquatic ecosystems. However, the interactive effects of multiple global environmental changes, including temperature rise and eutrophication, on aquatic plant stoichiometry and palatability remain largely unknown. Here, we hypothesized that (1) plant growth rates increase faster with rising temperature in nutrient-rich than nutrient-poor sediments; (2) plant carbon (C): nutrient ratios (nitrogen (N) and phosphorus (P)) respond differently to rising temperatures...
