Remarkable effects of microbial factors on soil phosphorus bioavailability: a country-scale study

Jin-Tian Li, Lu Jing-Li, Jia Pu, Feng Shi-Wei, Wang Yu-Tao, Zheng Jin, Ou Shu-Ning, Wu Zhuo-Hui, Liao Bin, Shu Wen-Sheng & Liang Jie-Liang
Low soil phosphorus (P) bioavailability causes the widespread occurrence of P-limited terrestrial ecosystems around the globe. Exploring the factors influencing soil P bioavailability at large spatial scales is critical for managing these ecosystems. However, previous studies have mostly focused on abiotic factors. In this study, we explored the effects of microbial factors on soil P bioavailability of terrestrial ecosystems using a countrycontinental-scale sampling effort. Our results showed that soil microbial biomass carbon (MBC) and acid...

Artificial selection on cis-element of Abl contributes cocoon yield increase in domestic silkworm

Hui Xiang
The silkworm (Bombyx mori) is an important silk-producing domestic insect. The quality and yield of the silk produced by B. mori exceeds that of its ancestor, the wild silkworm B. mandarina. However, to date little is known about the molecular mechanisms underlying domestication-related increases in silk yield. Here, we identified a gene associated with both domestication and silk-related quantitative trait locus (QTL): Abelson tyrosine protein kinase (Abl). Population genomic data for B. mori and B....

Data from: Plant diversity accurately predicts insect diversity in two tropical landscapes

Kai Zhang, Siliang Lin, Yinqiu Ji, Chenxue Yang, Xiaoyang Wang, Chunyan Yang, Hesheng Wang, Haisheng Jiang, Rhett D. Harrison & Douglas W. Yu
Plant diversity surely determines arthropod diversity, but only moderate correlations between arthropod and plant species richness had been observed until Basset et al. (Science, 338, 2012 and 1481) finally undertook an unprecedentedly comprehensive sampling of a tropical forest and demonstrated that plant species richness could indeed accurately predict arthropod species richness. We now require a high-throughput pipeline to operationalize this result so that we can (i) test competing explanations for tropical arthropod megadiversity, (ii) improve...

Data from: Vis/NIR reflectance spectroscopy for hybrid rice variety identification and chlorophyll content evaluation for different nitrogen fertilizer levels

Hao Zhang, Zheng Duan, Yiyun Li, Guangyu Zhao, Shiming Zhu, Wei Fu, Ting Peng, Quanzhi Zhao, Sune Svanberg & Jiandong Hu
Nitrogen is one of the most important nutrient indicator for the growth of crops, which is closely related to chlorophyll content of leaves and thus influences the photosynthetic ability of crops. In this study, visible and near infrared (vis/NIR) reflectance spectroscopy combined with multi-variate analysis was used to identify hybrid rice varieties and nitrogen fertilizer levels, as well as to detect chlorophyll content associated with nitrogen levels. The support vector machine (SVM) algorithm was applied...

Evolutionary history of zoogeographical regions surrounding the Tibetan Plateau

Jiekun He, Siliang Lin, Jiatang Li, Jiehua Yu & Haisheng Jiang
The Tibetan Plateau (TP) and surrounding regions have one of the most complex biotas on Earth. However, the evolutionary history of these regions in deep time is poorly understood. In this study, we quantified the temporal changes in beta dissimilarities among zoogeographical regions during the Cenozoic using 4,966 extant terrestrial vertebrates and 1,278 extinct mammal genera. We identified ten present-day zoogeographical regions and found that they underwent a striking change over time. Specifically, the fauna...

A dormant amoeba species can selectively sense and predate on different soil bacteria

Longfei Shu, Zhenzhen He, Xiaotong Guan, Xueqin Yang, Yuehui Tian, Siyi Zhang, Chenyuan Wu, Zhili He, Qingyun Yan, Cheng Wang & Yijing Shi
1. Soil protists are the invisible majority of soil eukaryotes, which are essential but often forgotten parts of the soil ecosystem. They play key roles in microbial food webs by predating on other soil microbes. However, it is not clear how dormant soil protists sense, recognize and feed on diverse microbial preys. 2. In this study, we used a soil amoeba, Dictyostelium discoideum, to study selective discrimination and predation of 14 different bacteria. We found...

Data from: Joint effects of environmental filtering and dispersal limitation on species assemblage of the Tibetan Plateau

Jiekun He, Haoxian Lin, Runxi Wang, Chao Dai, Hongyin Yu, Jiahao Tu, Jiehua Yu & Haisheng Jiang
Aim Mountains harbour a rich and non-random cluster of species, yet knowledge on the species’ biological attributes that support species coexistence in the montane community is limited. Here, we investigated the association of species occurrence on the Tibetan Plateau with species’ morphological, ecological or evolutionary constraints. Location Tibetan Plateau (TP) Taxon Mammals and birds Methods We tested whether species occurrence on the TP correlates with morphological, ecological, or evolutionary constraints using the spatial distribution, phylogeny,...

Genomic analysis finds no evidence of canonical eukaryotic DNA processing complexes in a free-living protist

Dayana Salas-Leiva, Eelco Tromer, Bruce Curtis, Jon Jerlström-Hultqvist, Martin Kolisko, Zhenzhen Yi, Joan Salas-Leiva, Lucie Gallot-Lavallée, Shelby Williams, Geert Kops, John Archibald, Alastair Simpson & Andrew Roger
Cells replicate and segregate their DNA with precision. Previous studies showed that these regulated cell-cycle processes were present in the last eukaryotic common ancestor and that their core molecular parts are conserved across eukaryotes. However, some metamonad parasites have secondarily lost components of the DNA processing and segregation apparatuses. To clarify the evolutionary history of these systems in these unusual eukaryotes, we generated a genome assembly for the free-living metamonad Carpediemonas membranifera and carried out...

Data from: Genetic differentiation between two varieties of Oreocharis benthamii (Gesneriaceae) in sympatric and allopatric regions

Ying-Qiang Wang, Qiong Fu, Guo-Hui Lu & Yu-Hui Fu
The pattern of genetic differentiation between diverging species receives much attention as one of the key observable features of speciation. It has often been suggested that introgression between closely related species occurs commonly where their distributions overlap, leading to their becoming more morphologically and genetically similar, but there are a few opposite results. However, most of these studies have been carried out with animals and separate species; few have looked at intraspecific cases, especially in...

Data from: Identifying litchi (Litchi chinensis Sonn.) cultivars and their genetic relationships using single nucleotide polymorphism (SNP) markers

Wei Liu, Zhidan Xiao, Xiuli Bao, Xiaoyan Yang, Jing Fang & Xu Xiang
Litchi is an important fruit tree in tropical and subtropical areas of the world. However, there is widespread confusion regarding litchi cultivar nomenclature and detailed information of genetic relationships among litchi germplasm is unclear. In the present study, the potential of single nucleotide polymorphism (SNP) for the identification of 96 representative litchi accessions and their genetic relationships in China was evaluated using 155 SNPs that were evenly spaced across litchi genome. Ninety SNPs with minor...

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,...

Grylloblattidan insects from Sperbersbach and Cabarz (Germany), two new early Permian and insect-rich localities

Yingying Cui, Stephan Brauner, Joerg W. Schneider & Olivier Béthoux
New fossil insect specimens from two new localities in Germany, namely Sperbersbach and Cabarz (Goldlauter Formation; early Permian), belonging to the Grylloblattida, are described. Abundant material is assigned to Pictoborella clara n. gen. n. sp., regarded as closely related to Pictoborella germanica (Prokop et al., 2012) n. comb., from the Saar-Nahe Basin (Germany; early Permian). Liomopterum fuscatum n. sp., represented by fewer specimens, is delimited based on previously published and new data on various Liomopterum...

Vegetation resistance and resilience to a decade-long dry period in the temperate grasslands in China

Minqi Liang, Ruochen Cao, Kai Di, Daorui Han & Zhongmin Hu
The duration of climate anomalies has been increasing across the globe, leading to ecosystem function loss. Thus, we need to understand the responses of the ecosystem to long-term climate anomalies. It remains unclear how ecosystem resistance and resilience respond to long-term climate anomalies, e.g., continuous dry years at a regional scale. Taking the opportunity of a 13-year dry period in the temperate grasslands in northern China, we quantified the resistance and resilience of the grassland...

Data from: Failure modes analysis of electrofluidic display under thermal aging

Baoqin Dong, Biao Tang, Groenewold Jan, Hui Li, Rui Zhou, Victor Henzen Alexander, Guofu Zhou, Jan Groenewold & Alexander Victor Henzen
Dielectric failure and optical switching failure in electro-fluidic display (EFD) is still a bottleneck for sufficient device lifetime. In this study, a dielectric redundancy-designed multilayer insulator of ParyleneC/AF1600X was applied in an EFD device. The reliability performance was systematically studied by tracking the applied voltage dependent leakage current and capacitance changes (I-V & C-V curve) with thermal aging time. The multilayer insulator shows a more stable performance in leakage current compared to that of single-layer...

Data from: The evolutionary road from wild moth to domestic silkworm

Hui Xiang, Xiaojing Liu, Muwang Li, Ya'nan Zhu, Lizhi Wang, Yong Cui, Liyuan Liu, Gangqi Fang, Heying Qian, Anying Xu, Wen Wang & Shuai Zhan
The Silk Road, which derives its name from the trade of silk produced by the domestic silkworm Bombyx mori, was an important episode in the development and interaction of human civilizations. However, the detailed history behind silkworm domestication remains ambiguous, and little is known about the underlying genetics with respect to important aspects of its domestication. Here, we reconstruct the domestication processes and identify selective sweeps by sequencing 137 representative silkworm strains. The results present...

Plant diversity enhances rehabilitation of degraded lands by spurring plant-soil feedbacks

Pu Jia, Jie-Liang Liang, Sheng-Xiang Yang, Sheng-Chang Zhang, Jun Liu, Zhi-Wei Liang, Feng-Mei Li, Qing-Wei Zeng, Zhou Fang, Bin Liao, Wen-Sheng Shu, Marc Cadotte & Jin-Tian Li
Despite a rich history of theoretical and empirical work showing that increasing biodiversity results in higher ecosystem function, this research has not made a commensurate impact on the reclamation of degraded lands, where enhancing ecosystem function is of primary importance. 2. In this study, we manipulated plant diversity on heavily degraded mine lands and showed that increasing plant diversity greatly enhanced the reclamation of these lands. We found that high diversity assemblages were often associated...

Island biogeography of soil bacteria and fungi: similar patterns, but different mechanisms

Shaopeng Li, Pandeng Wang, Yongjian Chen, Maxwell Wilson, Xian Yang, Chao Ma, Jianbo Lu, Xiao-Yong Chen, Jianguo Wu, Wen-Sheng Shu & Lin Jiang
Microbes, similar to plants and animals, exhibit biogeographic patterns. However, in contrast with the considerable knowledge on the island biogeography of higher organisms, we know little about the distribution of microorganisms within and among islands. Here, we explored insular soil bacterial and fungal biogeography and underlying mechanisms, using soil microbiota from a group of land-bridge islands as a model system. Similar to island species-area relationships observed for many macroorganisms, both island-scale bacterial and fungal diversity...

Data from: Geological and climatic histories likely shaped the origins of terrestrial vertebrates endemic to the Tibetan Plateau

Jiekun He, Siliang Lin, Chenchen Ding, Jiehua Yu & Haisheng Jiang
Aim The Tibetan Plateau (TP) hosts many endemic species, but questions regarding when and from where these species originated have not been comprehensively answered. Here, we provide a synthesis of the biogeographical history of terrestrial vertebrates endemic to the TP and investigate the potential drivers of their spatio-temporal origins. Location Tibetan Plateau and its surrounding regions Time period Cenozoic Major taxa studied Terrestrial vertebrates Methods We used dispersal–extinction–cladogenesis models based on time-calibrated phylogenies to reconstruct...

Data from: Cenozoic evolution of beta diversity and a Pleistocene emergence for modern mammal faunas in China

Jiekun He, Holger Kreft, Siliang Lin, Yang Xu & Haisheng Jiang
Aim Historical changes in community structure underlie modern spatial diversity patterns, but few empirical studies have focused on the variation in the community composition of fossil assemblages at large spatiotemporal scales. We wanted to investigat how the spatial differentiation of mammal communities changed in China throughout the Cenozoic in response to tectonic uplift and paleoclimatic changes and explore the timing of the emergence of the modern spatially structured faunas. Location China Time period Cenozoic (from...

Data from: Temporal intraspecific trait variability drives responses of functional diversity to inter-annual aridity variation in grasslands

Huiying Chen, Yongmei Huang, Kejian He, Yu Qi, Engui Li, Zhiyun Jiang, Zhilu Sheng & Xiaoyan Li
Inter-annual climate variation alters functional diversity through intraspecific trait variability and species turnover. We examined these diversity elements in three types of grasslands in Northern China, including two temperate steppes and an alpine meadow. We evaluated the differences in community-weighted means (CWM) of plant traits and functional dispersion (FDis) between two years with contrasting aridity in the growing season. Four traits were measured: specific leaf area (SLA), leaf dry matter content (LDMC), leaf nitrogen concentration...
