1The Impacts of Urbanization on the Distribution and Body Condition of the Rice-paddy Frog(Fejervarya multistriata) and Gold-striped Pond Frog(Pelophylax plancyi) in Shanghai,China显示文摘Previous studies have suggested that urbanization presents a major threat to anuran populations. However, very few studies have looked at the relationship between urbanization and anuran body condition. We investigated whether the distribution and body condition of the rice-paddy frog(Fejervarya multistriata) and gold-striped pond frog(Pelophylax plancyi) are influenced by increasing urbanization in Shanghai, China. Four study sites with six indicators of the major land-cover types were scored to indicate their position on an urbanization gradient. We found that both the density and body condition of F. multistriata declined significantly along this gradient. Although we observed a significant difference in body condition of P. plancyi among study sites with different degrees of urbanization, we did not find any corresponding significant differences in population density. Our results indicate that both the densities and body condition of these two anuran species show a negative relationship with increasing urbanization, but that the density of P. plancyi was only slightly affected in Shanghai.Ben LI Wei ZHANG Xiaoxiao SHU Enle PEI Xiao YUAN Yujie SUN Tianhou WANG Zhenghuan WANG 2016Asian Herpetological Research2016,7,3:9
2Major Factors Affecting the Distribution of Anuran Communities in the Urban, Suburban and Rural Areas of Shanghai, China显示文摘There is a dearth of information on the effects of landscape and microhabitat variables on the distribution of anurans in areas of rapid urban development, in both tropical and subtropical regions. Therefore, we studied 24 wetlands sites from the center of Shanghai city, China extending outward to rural areas. Sampling was performed from May through July 2014. Urbanization was categorized by the proportion of hard ground cover. Transect sampling and ‘calling' surveys were used to investigated the richness and density of anurans; microhabitat factors were recorded simultaneously. One-way analysis of variance and Kruskal–Wallis tests were conducted to analyze differences of total density, species richness and density of individual anuran species in the three urbanization levels; redundancy analysis was carried out on the relationship between anuran density and environmental variables. Species richness was lowest in the areas where the proportion of hard ground cover was > 80%, and the total density of anurans was highest in the areas where coverage of the hard ground cover was < 30%. We recorded five species belonging to four genera and four families and an individual anuran species that had varied representations in urban environments. Beijing gold-striped pond frogs(Pelophylax plancyi) and Zhoushan toads(Bufo gargarizans) appeared to be well adapted to the Shanghai metropolis. Large water environments and aquatic vegetation(floating-leaves and emergent vegetation) were indicators of the presence of Beijing gold-striped pond frogs. The density of black-spotted pond frog(Pelophylax nigromaculatus) was at the lowest density in the areas where hard ground coverage was > 80%, and tended to prefer larger bodies of water. Hong Kong rice-paddy frogs(Fejervarya multistriata) and ornamented pygmy frogs(Microhyla achatina) both suffered severely from cropland loss due to urban development. Bare land around breeding grounds was important for Hong Kong rice-paddy frogs, since it usually chooses mud coast caves for hibernation.Xiaoxiao SHU Wei ZHANG Ben LI Enle PEI Xiao YUAN Tianhou WANG Zhenghuan WANG 2016Asian Herpetological Research2016,7,4:6
3A New Record of Kaloula(Amphibia: Anura: Microhylidae) in Shanghai, China显示文摘We discovered a medium-sized species of narrow-mouthed frog of the genus Kaloula in June and September 2014 during municipal surveys of amphibians in Shanghai. Three narrow-mouthed frogs were collected in city drains of the Binjiang Forest Park, Shanghai. Based on subsequent examination and morphological characters, these specimens were identified as Kaloula borealis(Barbour, 1908). The species was mainly distributed in Northern China and Korea. It is a new amphibian record for Shanghai. We found the visible differences in male secondary sexual characteristics between our specimens and Beijing specimens. K. borealis was first described inhabiting urban greenlands which could benefit amphibian conservation in urban and urbanizing areas.Wei ZHANG Ben LI Xiaoxiao SHU Hanbin XIE Enle PEI Xiao YUAN Yujie SUN Tianhou WANG Zhenghuan WANG 2015Asian Herpetological Research2015,6,3:3
4Increased Expression of Colonic Mucosal Melatonin in Patients with Irritable Bowel Syndrome Correlated with Gut Dysbiosis显示文摘Dysregulation of the gut microbiota/gut hormone axis contributes to the pathogenesis of irritable bowel syndrome(IBS).Melatonin plays a beneficial role in gut motility and immunity.However,altered expression of local mucosal melatonin in IBS and its relationship with the gut microbiota remain unclear.Therefore,we aimed to detect the colonic melatonin levels and microbiota profiles in patients with diarrhea-predominant IBS(IBS-D)and explore their relationship in germ-free(GF)rats and BON-1 cells.Thirty-two IBS-D patients and twenty-eight healthy controls(HCs)were recruited.Fecal specimens from IBS-D patients and HCs were separately transplanted into GF rats by gavage.The levels of colon mucosal melatonin were assessed by immunohistochemical methods,and fecal microbiota communities were analyzed using 16S rDNA sequencing.The effect of butyrate on melatonin synthesis in BON-1 cells was evaluated by ELISA.Melatonin levels were significantly increased and negatively correlated with visceral hypersensitivity in IBS-D patients.GF rats inoculated with fecal microbiota from IBS-D patients had high colonic melatonin levels.Butyrate-producing Clostridium cluster XIVa species,such as Roseburia species and Lachnospira species,were positively related to colonic mucosal melatonin expression.Butyrate significantly increased melatonin secretion in BON-1 cells.Increased melatonin expression may be an adaptive protective mechanism in the development of IBS-D.Moreover,some Clostridium cluster XIVa species could increase melatonin expression via butyrate production.Modulation of the gut hormone/gut microbiota axis offers a promising target of interest for IBS in the future.Ben Wang Shiwei Zhu Zuojing Liu Hui Wei Lu Zhang Meibo He Fei Pei Jindong Zhang Qinghua Sun Liping Duan 2020Genomics, Proteomics & Bioinformatics2020,18,6:2

14Synthesis,characterization,and tunable wettability of poly (ionic liquid) brushes via nitroxide-mediated radical polymerization (NMP)显示文摘Well-defined poly(ionic liquid) brushes with tunable wettability are successfully synthesized via nitroxide-mediated radical polymerization.X-ray photoelectron spectroscopy,attenuated total reflection infrared spectroscopy and static water contact angle measurements are used to monitor each step.Ellipsometry,nuclear magnetic resonance(1H and 13C) spectra and gel permeation chromatographic measurements reveal that there is a linear increase in polymer film thickness with polymerization time,indicating that chain growth from the surface is a controlled/'living' polymerization.The surface morphology was measured by atomic force microscopy.Moreover,the surfaces of the poly(ionic liquid) brushes with tunable wettability and reversible switching between hydrophilicity and hydrophobicity can be easily achieved by counteranion exchange.YAG Wu HE XiaoJing GAO JinZhang GUO Hao HE XiaoYan WAN Fei ZHAO XiuLi YU Yan PEI Ben 2010Chinese Science Bulletin2010,55,31:1
