Data from: Opportunities for biodiversity gains under the world’s largest reforestation programme

Fangyuan Hua, Xiaoyang Wang, Xinlei Zheng, Robert Dorazio, Brendan Fisher, Lin Wang, Jianguo Zhu, Ya Tang, Douglas W. Yu & David S. Wilcove
Reforestation is a critical means of addressing the environmental and social problems of deforestation. China’s Grain-for-Green Program (GFGP) is the world’s largest reforestation scheme. Here we provide the first nationwide assessment of the tree composition of GFGP forests and the first combined ecological and economic study aimed at understanding GFGP’s biodiversity implications. Across China, GFGP forests are overwhelmingly monocultures or compositionally simple mixed forests. Focusing on birds and bees in Sichuan Province, we find that...

Data from: IL-33 mediated iLC2 activation and neutrophil IL-5 production in the lung response after severe trauma: a reverse translation study from a human cohort to a mouse trauma model

Jing Xu, Jesse Guardado, Rosemary Hoffman, Hui Xu, Rami Namas, Yoram Vodovotz, Li Xu, Mostafa Ramadan, Joshua Brown, Heth R. Turnquist & Timothy R. Billiar
Background: The immunosuppression and immune dysregulation that follows severe injury includes type 2 immune responses manifested by elevations in interleukin (IL) 4, IL5, and IL13 early after injury. We hypothesized that IL33, an alarmin released early after tissue injury and a known regulator of type 2 immunity, contributes to the early type 2 immune responses after systemic injury. Methods and findings: Blunt trauma patients admitted to the trauma intensive care unit of a level I...

Data from: Tailoring morphology of cobalt-nickel layered double hydroxide via different surfactants for high-performance supercapacitor

Bangqing Xiao, Wenliang Zhu, Zhong Li, Jiliang Zhu, Xiaohong Zhu & Giuseppe Pezzotti
Tailoring the surface morphology of cobalt-nickel layered double hydroxide (LDH) electrode materials was successfully achieved via the process of cathodical electrodeposition by adding different surfactants (hexamethyltetrammine (HMT), dodecyltrimethylammonium bromide (DTAB) or cetyltrimethylammonium bromide (CTAB)). The as-prepared Co0.75Ni0.25(OH)2 with surfactants exhibited wrinkle-like, cauliflower-like, or net-like structures that corresponded to distinct and better electrochemical performances than the untreated one. In particular, a specific capacitance of 1209.1 F g-1 was found for the cauliflower-like Co0.75Ni0.25(OH)2 electrode material using...

The distinguishing characters of these two species are presented and compared.

Data from: Invasive plants differentially affect soil biota through litter and rhizosphere pathways: a meta-analysis

Pei Zhang, Bo LI, Jihua Wu & Shuijin Hu
Invasive plants affect soil biota through litter and rhizosphere inputs, but the direction and magnitude of these effects are variable. We conducted a meta-analysis to examine the different effects of litter and rhizosphere of invasive plants on soil communities and nutrient cycling. Our results showed that invasive plants increased bacterial biomass by 16%, detritivore abundance by 119% and microbivore abundance by 89% through litter pathway. In the rhizosphere, invasive plants reduced bacterial biomass by 12%,...

Data from: Ferromagnetically filled carbon nano-onions: the key role of sulfur in dimensional, structural and electric control

Daniel Medranda, Joanna Borowiec, Xiaotian Zhang, Shanling Wang, Kai Yan, Jingdong Zhang, Yi He, Sameera Ivaturi, Filippo S. Boi & Xiao Zhang
A key challenge in the fabrication of ferromagnetically filled carbon nano-onions (CNOs) is the control of their thickness, dimensions and electric properties. Up to now literature works have mainly focused on the encapsulation of different types of ferromagnetic materials including α-Fe, Fe3C, Co, FeCo, FePd3 and others within CNOs. However, no report has yet shown a suitable method for controlling both the number of shells, diameter and electric properties of the produced CNOs. Here, we...

Data from: Prediction for electronic, vibrational and thermoelectric properties of chalcopyrite AgX(X=In,Ga)Te2: PBE + U approach

Jianhui Yang, Qiang Fan & Xinlu Cheng
The electronic, vibrational and thermoelectric transport characteristics of AgInTe2 and AgGaTe2 with chalcopyrite structure have been investigated. The electronic structures are calculated using the density-functional theory (DFT) within the generalized gradient approximation (GGA) of Perdew–Burke–Ernzerhof (PBE) functional considering the Hubbard-U exchange-correlation. The band-gaps of AgInTe2 and AgGaTe2 are much larger than previous standard GGA functional results and agree well with the existing experimental data. The effective mass of the hole and the shape of density...

Data from: An increase in immature β-cells lacking Glut2 precedes the expansion of β-cell mass in the pregnant mouse

Christine A. Beamish, Linhao Zhang, Sandra K. Szlapinski, Brenda J. Strutt & David J. Hill
A compensatory increase in β-cell mass occurs during pregnancy to counter the associated insulin resistance, and a failure in adaptation is thought to contribute to gestational diabetes. Insulin-expressing but glucose-transporter-2-low (Ins+Glut2LO) progenitor cells are present in mouse and human pancreas, being predominantly located in extra-islet β-cell clusters, and contribute to the regeneration of the endocrine pancreas following induced ablation. We therefore sought to investigate the contribution of Ins+Glut2LO cells to β-cell mass expansion during pregnancy....

Influence of early thermal-oxidative ageing on the structure and properties of polyoxymethylene copolymer

Yuan-Jin Pang, Wen-Shuai Xu, Ben-Tengzi Yang, Hai-Ying Ni & Jun Chen
Thermal-oxidative ageing of polyoxymethylene (POM) copolymer in oven at 100 °C for 1, 2, 3, 5, 7, 10, 14 and 21 days and the influence of early thermal-oxidative on POM structure and properties were studied by means of wide-angle X-ray diffraction (WAXD), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and tensile test. Based on the results, we found that the early thermal-oxidative ageing of POM copolymer can be divided into three regions. The...

Livestock grazing promotes ecosystem multifunctionality of a coastal saltmarsh

Pei Zhang, Zaichao Yang & Jihua Wu
The effects of livestock grazing on grasslands have garnered much attention; however, little is known about how grazing affects ecosystems’ ability to simultaneously support multiple ecosystem functions (i.e., ecosystem multifunctionality, hereafter EMF) in coastal saltmarshes. To comprehensively evaluate the ecological effects of livestock grazing and tidal flooding on saltmarshes, we conducted a grazing-exclusion experiment in the high and middle marsh zones of the Yangtze River Estuary, China. Livestock grazing generally enhanced EMF in the salt...

The draft genome of the blood pheasant (Ithaginis cruentus): phylogeny and high-altitude adaptation

Zhou Chuang
The blood pheasant (Ithaginis cruentus), the only species in the genus Ithaginis lives in an extremely inhospitable high-altitude environment, coping with hypoxia and UV radiation. To further investigate the phylogeny of Phasianidae species based on complete genomes and understand the molecular genetic mechanisms of the high-altitude adaptation of the blood pheasant, we de novo assembled and annotated the complete genome of the blood pheasant. The blood pheasant genome size is 1.04 Gb with scaf N50...

Assigning the sex-specific markers via genotyping-by-sequencing onto the Y chromosome for a torrent frog Amolops mantzorum

Luo Wei, Xia Yun, Yue Bisong & Zeng Xiaomao
We use a genotyping-by-sequencing (GBS) approach to identify sex-linked markers in a torrent frog (Amolops mantzorum) using wild-caught individuals of 21 males and 19 females from the same population. A total of 141 putatively sex-linked markers were screened from 1,015,964 GBS tags through three approaches, respectively based on sex differences in allele frequencies, sex difference in heterozygosity, and sex-limited occurrence. With validations, 69 sex-linked markers were confirmed, all of which point to male heterogamety. The...

Data from: Population genetic structure and intraspecific genetic distance of Periplaneta americana (Blattodea: Blattidae) based on mitochondrial and nuclear DNA markers

Jinnan Ma, Jinhua Liu, Yongmei Shen, Zhenxin Fan, Bisong Yue & Xiuyue Zhang
The American cockroach (Periplaneta americana) is a globally invasive pest that can cause significant economic loss and threaten human health. Although it is abundant and lives in close proximity to humans, few studies have investigated the genetic diversity of P. americana. Our study analyzed 1053 P. americana and other Periplaneta species’ samples from different locations in China and the USA. A traditional tree-based method using 17 unique mitochondrial COI haplotypes of P. americana and 20...

Landscape elevational connectivity: we underestimated the impact of stochastic processes on the spatial pattern of species richness

Taxing Zhang
We have begun to address the problem of species distribution patterns in three-dimensional space. Recently, a theory called “Landscape Elevational Connectivity” (LEC) has been developed, which measures how topography and geomorphology drive biodiversity patterns. Here, we estimated the spatial distribution pattern of bird species richness on the Tibetan Plateau using online species occurrence data, and we compared this estimated distribution with the predictions of LEC. We found a high correlation between the LEC null model...
