Data from: Abundance of small mammals correlates with their elevational range sizes and elevational distributions in the subtropics

Zhixin Wen, Yongjie Wu, Jilong Cheng, Tianlong Cai, Yuanbao Du, Deyan Ge, Lin Xia & Qisen Yang
The idea that a positive abundance-range size relationship (ARR) is pervasive in nature has been challenged by recent studies focused on montane and island vertebrate assemblages. However, because some of these studies used species’ local abundance and regional or global range size in examining the ARRs, the negative and neutral trends reported are questionable. Here, by relating species’ mean abundance along elevational gradients to elevational range size, we examined the ARRs of non-flying small mammals...

Enhanced Heterogenous Hydration of SO2 Through Immobilization of Pyridinic-N on Carbon Materials

Wanglai Cen, Longhua Zou, Ping Yan, Peng Lu, Dongyao Chen & Wei Chu
Carbon materials doped with nitrogen has long been utilized for SO2 removal from flue gases for the benefits of environment. The role of water is generally regarded as hydration of SO3 which is formed through the oxidization of SO2. However, the hydrolysis of SO2, especially on the surface of N doped carbon materials, was almost ignored. In this study, the hydrolysis of SO2 was investigated in detail on the pyridinic nitrogen (PyN) doped graphene (GP)...

Population genetic assessment of newly discovered, extremely small populations of Xanthocyparis Vietnamensis from southwestern China

Yu-Liang Jiang, Tsam Ju, Linda Neaves, Jia-Liang Li, Wei-Ning Tan, Yu-Song Huang, Yan Liu & Kang-Shan Mao
Xanthocyparis vietnamensis is an endangered species that is currently restricted to karst montane areas in southwestern China and Vietnam. This rare conifer was first recorded in 2002 from northern Vietnam and then in 2013 from Guangxi, China, yet little is known about its genetic diversity and population structure. We developed expressed sequence tag microsatellite markers (EST-SSR) for X. vietnamensis. Illumina HiSeq data were used to reconstruct the transcriptome of this species by de novo assembly....

Altitudinal dispersal process drives community assembly of montane small mammals

Zhixin Wen, Zhixin Wen, Feijo Anderson, Jinzhao Ke, Xingcheng He, Jilong Cheng, Deyan Ge, Tian Tian, Lin Xia, Yongjie Wu, Jianghong Ran & Qisen Yang
Montane small mammals are subjected to strong forces of dispersal limitation and habitat filtering that mainly operate on their community structures along the altitudinal direction. However, so far little is known about the relative contributions of dispersal and niche processes to their community assembly. By applying the newly-proposed PER-SIMPER/DNCI (dispersal–niche continuum index) framework to small mammal occurrence data collected from 21 extensive altitudinal gradients, we quantitatively assess the relative importance of dispersal and niche processes...

Data from: Phylogenetic niche conservatism and variations in species diversity-climate relationships

Qinggang Wang, Yaoqi Li, Dongting Zou, Xiangyan Su, Hongyu Cai, Ao Luo, Ke Jiang, Xiaoling Zhang, Xiaoting Xu, Nawal Shrestha & Zhiheng Wang
Although contemporary climate has been identified as one of the major determinants of large-scale species diversity patterns, its effect on species diversity greatly varies among clades. Understanding the drivers of the variation in species diversity-climate relationships (DCRs) across clades, which is critical for developing general mechanisms underlying the effects of climate on species diversity patterns, remains a current challenge. Using newly compiled distribution data of 914 Rosaceae species in China and a dated genus-level phylogeny,...

Data from: Genetic diversity and differentiation of the rhesus macaque (Macaca mulatta) population in western Sichuan, China, based on the second exon of the major histocompatibility complex class II DQB (MhcMamu-DQB1) alleles

Yong-Fang Yao, Qiu-Xia Dai, Jing Li, Qing-Yong Ni, Ming-Wang Zhang & Huai-Liang Xu
Background: Rhesus macaques living in western Sichuan, China, have been separated into several isolated populations due to habitat fragmentation. Previous studies based on the neutral or nearly neutral markers (mitochondrial DNA or microsatellites) showed high levels of genetic diversity and moderate genetic differentiation in the Sichuan rhesus macaques. Variation at the major histocompatibility complex (MHC) loci is widely accepted as being maintained by balancing selection, even with a low level of neutral variability in some...

Data from: Taylor's Power Law and its decomposition in urban facilities

Liang Wu, Chi Gong & Xin Yan
As one of the few generalities in ecology, Taylor's power law admits a power function relationship $V=aM^{b}$ between the variance $V$ and mean number $M$ of organisms in a quadrat. We examine the spatial distribution data of seven urban service facilities in 37 major cities in China, and find that Taylor's law is validated among all types of facilities. Moreover, Taylor's law is robust if we shift the observation window or vary the size of...

Data from: Diploid hybrid origin of Ostryopsis intermedia (Betulaceae) in the Qinghai-Tibet Plateau triggered by Quaternary climate change

Bingbing Liu, Richard J. Abbott, Zhiqiang Lu, Bin Tian & Jianquan Liu
Despite the well known effects that Quaternary climate oscillations had on shaping intraspecific diversity, their role in driving homoploid hybrid speciation is less clear. Here we examine their importance in the putative homoploid hybrid origin and evolution of Ostryopsis intermedia, a diploid species occurring in the Qinghai-Tibet Plateau (QTP), a biodiversity hotspot. We investigated interspecific relationships between this species and its only other congeners, O. davidiana and O. nobilis, based on four sets of nuclear...

After modification, the material surface become uneven with polyporous and crinkly structure, improving the Cr-accommodation ability in a sound manner. Optimized by Taguchi method, Cr(VI) removal efficiency was up to 73.88% with 240min, 40°C, pH 3, Cr(VI) at 200 mg L-1, dosage at 12 g L-1, rpm...

Data from: A complex pattern of post-divergence expansion, contraction, introgression and asynchronous responses to Pleistocene climate changes in two Dipelta sister species from western China

Bin Tian, Yi Fu, Richard Milne, Kangshan Mao, Yong-Shuai Sun, Xiangguang Ma & Hang Sun
The well-known vicariance and dispersal models dominate in understanding the allopatric pattern for related species and presume the simultaneous occurrence of speciation and biogeographic events. However, the formation of allopatry may postdate the species divergence. We examined this hypothesis using DNA sequence data from 3 chloroplast fragments and 5 nuclear loci of Dipelta floribunda and D. yunnanensis, two shrub species with the circum Sichuan Basin distribution, combining the climatic niche modeling approach. The best-fit model...

We aimed to investigate (i) the existence and types of publication agreements in trial protocols, (ii) the completeness and consistency of the reporting of these agreements in subsequent publications, and (iii) the frequency of co-authorship by industry employees. Methods and Findings: We used a retrospective cohort of randomized clinical...

Blow to the Northeast? Intraspecific differentiation of Populus davidiana suggests a northeastward skew of a phylogeographic break boundary in East Asia

Xiaoyan Fan, Xinya Song & Richard I. Milne
Aim: There is increasing interest in the role that biological traits, and historical and biogeographic processes, play in the formation of phylogeographic patterns. An arid belt that once existed in northern China might have affected many plants, but this has yet to be untested in an arid-tolerant, wind-dispersed species. Here we tested how intrinsic and extrinsic factors have affected the phylogeography of Populus davidiana. Location: East Asia Methods: Genetic variation was surveyed across 40 populations...

Flying over phylogeographic breaks by wind: Quaternary evolutionary history of a mountain aspen in southwestern China

Jieshi Tang
The role of phylogeographic break and wind direction in the formation of plant genetic pattern has aroused increasing interest. Two phylogeographic breaks, MSD and TKL, existed in the Sino-Japanese floristic region have affected many plants, but there was no landscape genetic research across these two phylogeographic breaks. Here, we tested the internal and external factors that influence the phylogeographic pattern of Populus rotundifolia. Genetic variation was surveyed across 49 populations (567 individuals) covering the Chinese...

Data from: Ferula paeoniifolia sp. nov. (Apiaceae) from Sichuan, China

Xiangguang Ma, Chenyang Liao, Yi Chen & Hanwen Xu
Ferula paeoniifolia X. G. Ma & C. Y. Liao sp. nov., from Sichuan Province, Southwest China, is described and illustrated. The new species is most similar to F. kingdon-wardii Wolff in morphology, but differs significantly in its ternate-2-pinnate compound leaves comprising much broader leaflets. The key morphological characteristics and nuclear ribosomal internal transcribed spacer (ITS) region were also compared between F. paeoniifolia and its relatives, which revealed a new species to Ferula L.

Data from: A consistent species richness-climate relationship for oaks across the Northern Hemisphere

Xiaoting Xu, Dimitar Dimitrov, Nawal Shrestha, Carsten Rahbek & Zhiheng Wang
Aim: Although the effects of climate on species richness are known, regional processes may lead to different species richness-climate relationships across continents resulting in species richness anomalies, especially for tropical groups. Phylogenetic niche conservatism may also influence species richness-climate relationships of different lineages. Here, we tested whether regional effects also exist for temperate lineages using the genus Quercus. Location: Northern Hemisphere Time period: Present day Major taxa studied: Quercus (Fagaceae) Methods: We used a dated...

Data from: Plastic transcriptomes stabilize immunity to pathogen diversity: the jasmonic acid and salicylic acid networks within the Arabidopsis/Botrytis pathosystem

Wei Zhang, Jason A. Corwin, Daniel Copeland, Julie Feusier, Robert Eshbaugh, Fang Chen, Susanna Atwell & Daniel J. Kliebenstein
To respond to pathogen attack, selection and associated evolution has led to the creation of plant immune system that are a highly effective and inducible defense system. Central to this system are the plant defense hormones jasmonic acid (JA) and salicylic acid (SA) and crosstalk between the two, which may play an important role in defense responses to specific pathogens or even genotypes. Here, we used the Arabidopsis-B. cinerea pathosystem to test how the host's...
