1微塑料污染的水生生态毒性与载体作用显示文摘近年来,微塑料的水生生态环境污染与生态毒害问题引起了科学界的广泛关注。在总结国内外相关研究的基础上,本文对水生态环境中微塑料的来源、形成与分布展开分析;对微塑料污染的生态毒性研究进展给予评述;并深入探讨了微塑料在生态系统中扮演的多重载体角色。鉴于微塑料污染的严峻现实,我国应尽快开展有关微塑料环境污染和生态毒理方面的系统研究,并辅以政策引导和经济支持。陈启晴 杨守业 Henner Hollert 尹大强 2018生态毒理学报2018,13,1:26
23个中国地方黄牛品种遗传结构及其遗传分化的研究显示文摘利用12对微卫星引物对中国3个地方黄牛品种(鲁西黄牛、渤海黑牛及闽南黄牛)及2个对照群体(中国荷斯坦牛和青海牦牛)的群体遗传结构、遗传分化及基因流水平进行研究,结合聚类分析,结果表明:5个牛群体总近交系数(Fit)为58.5%,群体内近交系数(Fis)为43.2%,群体间基因分化系数(Fst)为26.9%,3个指标均达到极显著水平(P<0.001)。5个牛群体内近交系数(Fis)鲁西黄牛最高(0.640),青海牦牛最低(0.231)。鲁西黄牛与荷斯坦牛间每世代群体间有效迁移个体数(Nem)最大(1.149),牦牛与鲁西黄牛间最小(0.509)。5个牛群体每个体属于所属群体的平均概率从91.4%到98.5%不等。结合聚类分析、基因流分析及STRUCTURE分析结果,5个牛群可分为3大类:鲁西黄牛和中国荷斯坦牛为一类,渤海黑牛和闽南黄牛为一类,牦牛自为一类,这说明在鲁西黄牛和渤海黑牛的形成过程中,鲁西黄牛受普通牛影响较大,而渤海黑牛受瘤牛影响较大,同时探讨了以上品种的演化与形成过程。毛永江 常洪 杨章平 张柳 许明 孙伟 常国斌 宋光明 Henner Simianer 2007畜牧兽医学报2007,38,2:9
3Yangtze Three Gorges Reservoir, China: A holistic assessment of organic pollution, mutagenic effects of sediments and genotoxic impacts on fish显示文摘Besides obvious benefits,the Three Gorges Dam's construction resulted in new pollution scenarios with the potentials to threaten the Three Gorges Reservoir(TGR) ecosystem.In order to record organic contamination,to find links to ecotoxicological impacts and to serve as reference for ensuing monitoring,several sites in the TGR area were screened applying the triad approach with additional lines-of-evidence as a holistic assessment method.Sediments and the benthic fish species Pelteobagrus vachellii were sampled in 2011 and 2012 to determine organic pollution levels,mutagenic potentials and genotoxic impacts.Two regional hot-spots near the cities of Chongqing and Kaixian were identified and further investigated in 2013.Only polycyclic aromatic hydrocarbons(PAHs) could be detected in sediments in 2011(165–1653 ng/g),emphasizing their roles as key pollutants of the area.Their ubiquity was confirmed at Chongqing(150–433 ng/g) and Kaixian(127–590 ng/g) in2013.Concentrations were comparable to other major Chinese and German rivers.However,the immense sediment influx suggested a deposition of 216–636 kg PAH/day(0.2–0.6 mg PAH/(m2·day)),indicating an ecotoxicological risk.PAH source analysis highlighted primary impacts of combustion sources on the more industrialized upper TGR section,whereas petrogenic sources dominated the mid-low section.Furthermore,sediment extracts from several sites exhibited significant activities of frameshift promutagens in the Ames fluctuation assay.Additionally,significant genotoxic impairments in erythrocytes of P.vachellii were detected(Chongqing/Kaixian),demonstrating the relevance of genotoxicity as animportant mode of action in the TGR's fish.PAHs,their derivatives and non-target compounds are considered as main causative agents.Tilman Floehr Bj?rn Scholz-Starke Hongxia Xiao Josef Koch Lingling Wu Junli Hou Anja Wolf Axel Bergmann Kerstin Bluhm Xingzhong Yuan Martina Ro?-Nickoll Andreas Sch?ffer Henner Hollert 2015Journal of Environmental Sciences2015,27,12:9
4植物在修复、固定和重建水生、陆生生态系统中的应用显示文摘植物能够吸收或降解污染物来修复受污染的土壤和水体[1-2],还能固定土壤、泥沙防止侵蚀和污染物从固体介质中释放[3]。众多无机和有机污染物都能被对其有耐性且生物量大的植物有效降解。例如,凤眼莲能吸收和净化来自金矿采掘废水的氰化物,这类废水含各种氰化物以及重金属元素的浓度达到导致生物体产生毒性效应的水平。检测表明氰化物对凤眼莲的半数致死剂量(LC50)为13 mg/L,将经过高浓度氰化物废水驯化后的凤眼莲放在野外小型湿地进行试验,结果显示这类植物对氰化物的降解效率更高。放射性同位素试验发现氰化物分子中的C和N原子经过植物代谢合成天冬酰胺,从而将有毒性的氰化物转化为无毒的产物[4]。尾矿场也可以用植物来修复,一方面植物可以过滤污染物浓度很高的渗滤液,另一方面栽种植物可以固定边坡减少侵蚀。将高覆盖度植被的概念应用在一个尾矿场上,通过种植北美黄杉使其全年都维持较高的蒸腾效率来减少渗滤液。而边坡的固定首先需要在坡面安置固定、菱形的新鲜柳条编织成的笼状网格,其后覆上土壤并喷播能在生长期对固定土壤发挥作用的草本、灌木以及树木种子。这项技术同样适用于河岸侵蚀防护。Andreas SCHAEFFER 陈忠礼 Mathias EBEL Michael EVANGELOU Henner HOLLERT Martina RO-NICKOLL Burkhard SCHMIDT 袁野 Gottfried LENNARTZ 2012重庆师范大学学报(自然科学版)2012,29,3:4
5遗传距离与利用微卫星进行系统树构建初探显示文摘以中国牛亚科家畜6个群体12对微卫星数据为基础,采用6种遗传距离(DA、DC、DS、Dsw,(σμ)2和DTL)和2种聚类方法(UPGMA和NJ法),探索它们对系统树构建准确性的影响。结果表明:微卫星位点平均杂合度水平显著影响系统树构建的准确性,用DA和DC遗传距离构建的系统树准确性相对较高,但很难确定NJ法和UPGMA法哪一种更适合于系统树的构建,而DTL遗传距离用于系统树构建有待进一步完善;最后,对微卫星用于家畜系统树构建的有效性和局限性进行了探讨。毛永江 常洪 杨章平 张柳 许明 常国斌 孙伟 宋光明 Henner Simianer 2008畜牧兽医学报2008,39,2:4
6Animal phylogeny and large-scale sequencing: progress and pitfalls显示文摘Phylogenomics, the inference of phylogenetic trees using genome-scale data, is becoming the rule for resolving difficult parts of the tree of life. Its promise resides in the large amount of information available, which should eliminate stochastic error. However, systematic error, which is due to limitations of reconstruction meth-ods, is becoming more apparent. We will illustrate, using animal phylogeny as a case study, the three most effi-cient approaches to avoid the pitfalls of phylogenomics: (1) using a dense taxon sampling, (2) using probabilistic methods with complex models of sequence evolution that more accurately detect multiple substitutions, and (3) removing the fastest evolving part of the data (e.g., species and positions). The analysis of a dataset of 55 animal species and 102 proteins (25712 amino acid positions) shows that standard site-homogeneous model inference is sensitive to long-branch attraction artifact, whereas the site-heterogeneous CAT model is less so. The latter model correctly locates three very fast evolving species, the appendicularian tunicate Oikopleura, the acoel Convoluta and the myxozoan Buddenbrockia. Overall, the resulting tree is in excellent agreement with the new animal phylogeny, confirming that 'simple' organisms like platyhelminths and nematodes are not necessarily of basal emergence. This further emphasizes the importance of secondary simplification in animals, and for organismal evolution in general.Henner BRINKMANN Herve PHILIPPE 2008植物分类学报2008,46,3:3
