Data from: Effects of light and topography on regeneration and coexistence of evergreen and deciduous tree species in a Chinese subtropical forest

Yi Jin, Sabrina E. Russo & Mingjian Yu
1. Evergreen broad-leaved forests are widely distributed in eastern Asia with evergreen (EBL) and deciduous (DBL) broad-leaved tree species coexisting under the same climatic regime, raising questions as to the underlying mechanisms. Since EBL and DBL species differ in leaf lifespan, a key component of resource economic strategies, their coexistence might be attributed to regeneration niche partitioning across habitats varying in resource supply. 2. We investigated the effects of variation in insolation and topography on...

Data from: A superlinear iteration method for calculation of finite length journal bearing's static equilibrium position

Wenjie Zhou, Xuesong Wei, Guangkuan Wu & Leqin Wang
Solving the static equilibrium position is one of the most important parts of dynamic coefficients calculation and further coupled calculation of rotor system. The main contribution of this study is testing the superlinear iteration convergence method - twofold secant method, for determination of the static equilibrium position of journal bearing with finite length. Essentially, the Reynolds equation for stable motion is solved by finite difference method and the inner pressure is obtained by successive over-relaxation...

Data from: Ecological correlates of extinction risk in Chinese birds

Yanping Wang, Xingfeng Si, Peter M. Bennett, Chuanwu Chen, Di Zeng, Yuhao Zhao, Yiru Wu & Ping Ding
China is one of the countries with the richest bird biodiversity in the world. Among the 1372 Chinese birds, 146 species are considered threatened and three species are regionally extinct according to the officially released China Biodiversity Red List in 2015. Here, we conducted the first extensive analysis to systematically investigate the patterns and processes of extinction and threat in Chinese birds. We addressed the following four questions. First, is extinction risk randomly distributed among...

Data from: Population structure and historical demography of Dipteronia dyeriana (Sapindaceae), an extremely narrow palaeoendemic plant from China: implications for conservation in a biodiversity hot spot

Chen Chen, Ruisen S. Lu, Shanshan S. Zhu, Tamaki Ichiro & Qiu X. Yingxiong
Inferring past demography is a central question in evolutionary and conservation biology. It is, however, sometimes challenging to disentangle their roles of contemporary versus historical processes in shaping the current patterns of genetic variation in endangered species. In this study, we used both chloroplast microsatellite (cpSSR) loci and nuclear microsatellite (nSSR) loci to assess the levels of genetic differentiation, genetic effective population size, contemporary/historical levels of gene flow and demographic history for five populations sampled...

Data from: Different genetic structures revealed resident populations of a specialist parasitoid wasp in contrast to its migratory host

Shu-Jun Wei, Yuan Zhou, Xu-Lei Fan, Ary A. Hoffmann, Li-Jun Cao, Xue-Xin Chen & Zai-Fu Xu
Genetic comparisons of parasitoids and their hosts are expected to reflect ecological and evolutionary processes that influence the interactions between species. The parasitoid wasp, Cotesia vestalis, and its host diamondback moth (DBM), Plutella xylostella, provide opportunities to test whether the specialist natural enemy migrates seasonally with its host or occurs as resident population. We genotyped 17 microsatellite loci and two mitochondrial genes for 158 female adults of C. vestalis collected from 12 geographical populations, as...

Data from: Facilitation among plants can accelerate density-dependent mortality and steepen self-thinning lines in stressful environments

Wei-Ping Zhang, Xin Jia & Gen-Xuan Wang
The speed and slope of plant self-thinning are all affected by plant-plant interactions across environmental gradients. Possible mechanisms driving the self-thinning dynamics include the relative strength of root vs. shoot competition, and the interplay between competition and facilitation. Although these mechanisms often act in concert, their relative importance has not yet been fully explored. We used both a one-layer and a two-layer zone-of-influence (ZOI) model to examine how competition and facilitation drive self-thinning across stress...

RETRACTED ARTICLE: Linc00152 promotes malignant progression of glioma stem cells by regulating miR-103a-3p/FEZF1/CDC25A pathway

Mingjun Yu, Yixue Xue, Jian Zheng, Xiaobai Liu, Hai Yu, Libo Liu, Zhen Li & Yunhui Liu
Abstract Background Glioma is one of the most frequent intracranial malignant tumors. LncRNAs have been identified as new modulators in the origination and progression of glioma. Methods Quantitative real-time PCR were conducted to evaluate the expression of linc00152 and miRNA-103a-3p in glioma tissues and cells. Western blot were used to determine the expression of FEZF1 and CDC25A in glioma tissues and cells. Stable knockdown of linc00152 or over-expression of miR-103a-3p in glioma stem cells (GSCs)...

Data from: Molecular analysis of caffeoyl residues related to pigmentation in green cotton fibers

Hongjie Feng, Yonglin Yang, Shichao Sun, Yanjun Li, Lin Zhang, Jingkui Tian, Qianhao Zhu, Zili Feng, Heqin Zhu & Jie Sun
The pigment components in green cotton fibers were isolated and identified as 22-O-caffeoyl-22-hydroxymonodocosanoin and 22-O-caffeoyl-22-hydroxydocosanoic acid. The concentration of 22-O-caffeoyl-22-hydroxymonodocosanoin was correlated positively with the degree of green fibers of color, indicating a role of caffeoyl derivatives in pigmentation of green cotton fibers. Upland cotton (Gossypium hirsutum L.) contains four genes (Gh4CL1 to Gh4CL4) encoding 4-coumarate:CoA ligase (4CL), key enzymes of the phenylpropanoid biosynthesis pathway. In 15 to 24 days-post anthesis fibers, the expression level...
