Comprehensive diagnosis of polychlorinated dibenzo-p-dioxin and dibenzofuran (PCDD/F) emissions was systematically conducted on three hazardous waste incinerators (HWIs.) Results indicated that PCDD/F mainly existed in the solid phase before the bag filter. This was especially true for higher chlorinated dioxin and furan congeners (hexa-, hepta- and octa-.) The aged bag filters tended to increase the gas-phase PCDD/F. Emissions also increased due to PCDD/F desorption from circulated scrubbing solution and plastic packing media used in the...
Data from: MHC class I diversity predicts non-random mating in Chinese alligators (Alligator sinensis)Qun-Hua Han, Ru-Na Sun, Hai-Qiong Yang, Zhen-Wei Wang, Qiu-Hong Wan & Sheng-Guo Fang
The major histocompatibility complex (MHC) plays numerous important roles in kin recognition, pathogen resistance, and mate selection. Research in fish, birds, and mammals have suggested that individuals optimize MHC diversity, and therefore offspring fitness, when choosing mates. In reptiles, however, it is unclear whether female mate choice is based on genome-wide genetic characteristics such as microsatellites DNA loci, on particular functional trait loci (e.g., MHC) or on both, and MHC effects on mate choice remain...
Data from: Expression plasticity and evolutionary changes extensively shape the sugar-mimic alkaloid adaptation of non-digestive glucosidase in lepidopteran mulberry-specialist insectsXiaotong Li, Liangen Shi, Xiangping Dai, Yajie Chen, Hongqing Xie, Min Feng, Yuyin Chen & Huabing Wang
During the co-evolutionary arms race between plants and herbivores, insects evolved systematic adaptive plasticity to minimise the chemical defence effects of their host plants. Previous studies mainly focused on the expressional plasticity of enzymes in detoxification and digestion. However, the expressional response and adaptive evolution of other fundamental regulators against host phytochemicals are largely unknown. Glucosidase II (GII), which is composed of a catalytic GIIα subunit and a regulatory GIIβ subunit, is an evolutionarily conserved...
Data from: Impacts of species richness on productivity in a large-scale subtropical forest experimentYuanyuan Huang, Yuxin Chen, Nadia Castro-Izaguirre, Martin Baruffol, Matteo Brezzi, Anne Lang, Ying Li, Werner Härdtle, Werner Von Oheimb, Xuefeu Yang, Xiaojuan Liu, Kequan Pei, Sabine Both, Bo Yang, David Eichenberg, Thorsten Assmann, Jürgen Bauhus, Thorsten Behrens, François Buscot, Xiao-Yong Chen, Douglas Chester, Bing-Yang Ding, Walter Durka, Alexandra Erfmeier, Jingyun Fang … & Bernhard Schmid
Biodiversity experiments have shown that species loss reduces ecosystem functioning in grassland. To test whether this result can be extrapolated to forests, the main contributors to terrestrial primary productivity, requires large-scale experiments. We manipulated tree species richness by planting more than 150,000 trees in plots with 1 to 16 species. Simulating multiple extinction scenarios, we found that richness strongly increased stand-level productivity. After 8 years, 16-species mixtures had accumulated over twice the amount of carbon...
Data from: Spatial phylogenetics reveals evolutionary constraints on the assembly of a large regional floraDaniel Spalink, Ricardo Kriebel, Pan Li, Matthew C. Pace, Bryan T. Drew, John G. Zaborsky, Jeffrey R. Rose, Chloe P. Drummond, Mary Ann Feist, William S. Alverson, Donald M. Waller, Kenneth M. Cameron, Thomas J. Givnish & Kenneth J. Sytsma
Premise of the study: We use spatial phylogenetics to analyze the assembly of the Wisconsin flora, linking processes of dispersal and niche evolution to spatial patterns in floristic and phylogenetic diversity, and testing whether phylogenetic niche conservatism can account for these patterns. Methods: We use digitized records and a new molecular phylogeny for all vascular plants in Wisconsin to estimate spatial variation in species richness and phylogenetic and diversity in a native flora...
Data from: Cascading effects of forested area and isolation on seed dispersal effectiveness of rodents on subtropical islandsDi Zeng, Robert K. Swihart, Yuhao Zhao, Xingfeng Si & Ping Ding
1. Habitat loss and fragmentation often leads to defaunation of large-bodied mammals, and their loss could trigger release from top-down control or food resource competition for small mammal seed dispersers, which in turn may affect the effectiveness of seed dispersal by altering the number of dispersed seeds or the manner in which they are dispersed. Although rodents are primary seed dispersers in habitat subjected to defaunation, changes in seed dispersal effectiveness of rodents along mammalian...
Clinical case reports (CCRs) provide an important means of sharing clinical experiences about atypical disease phenotypes and new therapies. However, published case reports contain largely unstructured and heterogeneous clinical data, posing a challenge to mining relevant information. Current indexing approaches generally concern document-level features and have not been specifically designed for CCRs. To address this disparity, we developed a standardized metadata template and identified text corresponding to medical concepts within 3,100 curated CCRs spanning 15...
Data from: Loss of miR-143 and miR-145 in condyloma acuminatum promotes cellular proliferation and inhibits apoptosis by targeting NRASXiaoyan Liu, Yu Zhang, Su Wang, Guoying Liu & Liming Ruan
The expression profile of miRNAs and their function in condyloma acuminatum (CA) remains unknown. In this study, we aimed to detect the effects of miR-143 and miR-145, the most downregulated in CA samples using high-throughput sequencing, on cell proliferation and apoptosis, to determine a novel therapeutic target for CA recurrence. RT-qPCR was used to validate the lower expression of miR-143 and miR-145 in a larger size of CA samples, and the expression of NRAS in...
Data from: Preparation of nanoporous BiVO4/TiO2/Ti film through electrodeposition for photoelectrochemical water splittingHongxing Dong, Qiuping Liu, Yuehui He, He Yuehui & Liu Qiuping
A nanoporous BiVO4/TiO2/Ti film was successfully fabricated by electrodepositing a nanoporous BiOI film on nanoporous TiO2 arrays followed by annealing at 450°C for 2 h. The electrodeposition of BiOI film was carried out at different times (10, 30, 100, 500, and 1000 s) in Bi(NO3)3 and KI solution. The morphological, crystallographic, and photoelectrochemical properties of the prepared BiVO4/TiO2/Ti heterojunction film were examined by using different characterization techniques. UV-vis spectrum absorption studies confirmed an increase in...
In this study, the electromagnetic (EM) performance of talc/NiTiO3 composite was evaluated. The morphology of talc displayed a lamella structure; there were many nanoparticles of NiTiO3 coated on the talc lamella. Thermal destruction occurred, which increased the surface area from 2.51 m2 g−1 to 79.09 m2 g−1 at the calcined stage at 650°C. The presence of NiTiO3 increased dielectric loss and magnetic loss of talc. The calculation of EM wave absorption of talc/NiTiO3 obtained a...
Data from: How do similarities in spatial distributions and interspecific associations affect the coexistence of Quercus species in the Baotianman National Nature Reserve, Henan, ChinaZhiliang Yuan, Boliang Wei, Yun Chen, Hongru Jia, Qingning Wei & Yongzhong Ye
Congeneric species often have similar ecological characteristics and use similar resources. These similarities may make it easier for them to co-occur in a similar habitat but may also lead to strong competitions that limit their coexistence. Hence, how do similarities in congeneric species affect their coexistence exactly? This study mainly used spatial point pattern analysis in two 1 hm2 plots in the Baotianman National Nature Reserve, Henan, China, to compare the similarities in spatial distributions...
Data from: Larger fragments have more late-successional species of woody plants than smaller fragments after 50 years of secondary successionJiajia Liu, David Coomes, Guang Hu, Jinliang Liu, Jingjing Yu, Yangqing Luo, Mingjian Yu & David A. Coomes
1. Most fragmentation research focuses on the effects of carving up old-growth forests, but less is known about influences of habitat fragmentation on secondary succession in patches of regenerating forests. 2. Working with forest dynamics on islands in a vast lake created by a hydroelectric dam in China (the Thousand Island Lake), we sampled 29 islands that were cleared of forest during dam construction in 1959 and then underwent succession. Measurements taken in 2009-2010 and...
