1Heavy Metal Transfer from Soil to Vegetable in Southern Jiangsu Province, China显示文摘Vegetable fields in peri-urban areas receive large amounts of extraneous heavy metals because of rapid urbanization and industrialization in China. The concentrations of Cu, Zn, and Pb in 30 soil samples and 32 vegetable samples, collected from 30 different sites in southern Jiangsu Province of China, were measured and their transfer from soil to vegetable was determined. The results showed that the soil samples had wide ranges of pH (4.25–7.85) and electrical conductivity (EC) (0.24–3.42 dS m-1). Among the soil samples, there were four soil samples containing higher Cu and two soil samples containing higher Zn concentrations than those specified in the Chinese Soil Environmental Quality Standard II. However, no vegetable sample was found to contain a high level of Cu or Zn. In contrast, one vegetable sample contained 0.243 mg Pb kg-1 FW, which was above the Chinese Food Hygiene Standard, whereas the corresponding soil Pb concentration was lower than the Chinese Soil Environmental Quality Standard II. The transfer coefficients of Cu of all vegetable samples exceeded the suggested coefficient range, implying that extraneous Cu had high mobility and bioavailability to vegetables. There was no significant correlation between extractable soil heavy metal concentrations with four kinds of extractants and soil pH, EC, heavy metal concentrations in vegetables and soils, except that soil pH correlated well with the extractable soil Cu, Zn, and Pb concentrations with 1.0 mol L-1 NH4NO3. Moreover, diethylenetriamine pentaacetic acid (DTPA) extraction method was a more effcient method of extracting heavy metals from the soils independent of soil pH and EC than other three methods used.HAO Xiu-Zhen ZHOU Dong-Mei HUANG De-Qian CANG Long ZHANG Hai-Lin WANG Hui 2009Pedosphere2009,19,3:46
2Gene expression alteration during redox-dependent enhancement of arsenic cytotoxicity by emodin in HeLa cells显示文摘Emodin (1,3,8-trihydroxy-6-methylanthraquinone) could enhance the sensitivity of tumor cells to arsenic trioxide(As2O3)–induced apoptosis via generation of ROS, but the molecular mechanism has not been elucidated. Here, wecarried out cDNA microarray-based global transcription profiling of HeLa cells in response to As2O3/emodin cotreatment,comparing with As2O3–only treatment. The results showed that the expression of a number of genes was substantiallyaltered at two time points. These genes are involved in different aspects of cell function. In addition to redox regulationand apoptosis, ROS affect genes encoding proteins associated with cell signaling, organelle functions, cell cycle,cytoskeleton, etc. These data suggest that based on the cytotoxicity of As2O3, emodin mobilize every genomic resourcethrough which the As2O3–induced apoptosis is facilitated.Xiao Jing WANG Jie YANG Hui CANG Yan Qiong ZOU Jing YI 2005Cell Research2005,15,7:28

6Balanced solubility product and enthalpies of formation of Nb compounds in 0.09 % oriented silicon steel显示文摘Balance solubility products and enthalpy of formation for NbC0.75 , NbC0.85 , NbC0.88 , NbC and NbN in oriented silicon steels were calculated and compared qualitatively. Meanwhile, the mixing enthalpies of these five Nb compounds were calculated based on Miedema Model. The results show that the solubility products of Nb compounds in ferrite and austenite meet the following relationship, NbC0.75>NbC0.85> NbC0.88>NbC>NbN and NbN has the minimum enthalpy of formation. It indicates that NbN easily precipitate out, but it is more difficult for NbC 0.75 .Hui Li Yun-Li Feng Dan Zhang Meng Song Da-Qiang Cang 2013Rare Metals2013,32,3:6
7Cascade effects of crop species richness on the diversity of pest insects and their natural enemies显示文摘Understanding how plant species richness influences the diversity of herbivorous and predatory/parasitic arthropods is central to community ecology.We explore the effects of crop species richness on the diversity of pest insects and their natural enemies.Using data from a four-year experiment with five levels of crop species richness,we found that crop species richness significantly affected the pest species richness,but there were no significant effects on richness of the pests’natural enemies.In contrast,the species richness of pest insects significantly affected their natural enemies.These findings suggest a cascade effect where trophic interactions are strong between adjacent trophic levels,while the interactions between connected but nonadjacent trophic levels are weakened by the intermediate trophic level.High crop species richness resulted in a more stable arthropod community compared with communities in monoculture crops.Our results highlight the complicated cross-trophic interactions and the crucial role of crop diversity in the food webs of agro-ecosystems.SHI PeiJian HUI Cang MEN XingYuan ZHAO ZiHua OUYANG Fang GE Feng JIN XianShi CAO HaiFeng LI B.Larry 2014Science China(Life Sciences)2014,57,7:6
8Variation in individual biomass decreases faster than mean biomass with increasing density of bamboo stands显示文摘The total biomass of a stand is an indicator of stand productivity and is closely related to the density of plants. According to the self-thinning law, mean individual biomass follows a negative power law with plant density. If the variance of individual biomass is constant, we can expect increased stand productivity with increasing plant density. However, Taylor's power law(TPL) that relates the variance and the mean of many biological measures(e.g. bilateral areal differences of a leaf, plant biomass atdifferent times, developmental rates at different temperatures, population densities on different spatial or temporal scales), affects the estimate of stand productivity when it is defined as the total biomass of large plants in a stand.Because the variance of individual biomass decreases faster than mean individual biomass, differences in individual biomass decline with increasing density, leading to more homogeneous timbers of greater economic value. We tested whether TPL in plant biomass holds for different species and whether the variance of individual biomass changes faster than the mean with increasing stand density.The height, ground diameter and fresh weight of 50 bamboo species were measured in 50 stands ranging from 1 m by 1 m to 30 m by 30 m to ensure more than 150 bamboos in every stand. We separately examined TPL in height,ground diameter, and weight, and found that TPL holds for all three biological measures, with the relationship strongest for weight. Using analysis of covariance to compare the regression slopes of logarithmic mean and variance against the logarithm of density, we found that the variance in individual biomass declined faster than the mean with increasing density. This suggests that dense planting reduced mean individual biomass but homogenized individual biomass. Thus, there exists a trade-off between effective stand productivity and stand density for optimal forest management. Sparse planting leads to large variation in individual biomass, whereas dense planting reduces mean individual biomass. Consequently, stand density for a plantation should be set based on this trade-off with reference to market demands.Guohua Liu Cang Hui Ming Chen Lauren SPile GGeoff Wang Fusheng Wang Peijian Shi 2020Journal of Forestry Research2020,31,3:2

12Assembly of plant communities in coastal wetlands--the role of saltcedar Tamarix chinensis during early succession显示文摘Aims The mechanisms of plant community assembly are hypothesized to vary at different stages of succession.Here,we explore the local assemblage structure of a herbaceous plant community at its early stage of succession in a supratidal wetland.specifically,we assess the role of Chinese saltcedar(Tamarix chinensis),the lone dominant shrub species,in shaping the spatial structure and species composi-tion in the local plant community,after landscape alteration.Methods We used the multivariate trend-surface analysis for analyzing the spatial structure of the community composition.a null model was also used to detect potential biotic interactions between species.statistical significance was derived from a permutation test by randomizing the presence-absence matrix and functional traits independently.sensitivity analysis by randomly selecting 50 subplots and repeating the null model tests was also done.Finally,rank correlation analysis was used to study the relationship between effect sizes and distance to nearest T.chinensis individuals.Important Findings The herbaceous plant community was highly structured and shaped by the presence of T.chinensis.at local scale,two functional traits,plant height and leaf area,were found to be significantly convergent.Dispersal,environmental stress and interspecific competition played a trivial effect on the local community assembly.The facilitating effect of T.chinensis on the pioneering herbaceous plants,through acting as a wind shelter,was put forward as the dominant community assembly process.Meng Gao Xinxiu Wang Cang Hui Huapeng Yi Chuanqi Zhang Xiaoqing Wu Xiaoli Bi Yong Wang Luxiang Xiao De Wang 2015Journal of Plant Ecology2015,8,5:1
