青海湖裸鲤的起源和花斑裸鲤的种群演化

通过线粒体Cytb基因全序列分析,探讨了青海湖裸鲤和花斑裸鲤的起源关系及其进化模式.系统发育分析进一步支持了青海湖裸鲤和花斑裸鲤3个mtDNA谱系的划分.形态上具有高鳃耙变异的个体未形成特有的进化枝,证明了第一鳃弓外鳃耙变异并不具有系统发育意义.对青海湖裸鲤和花斑裸鲤进化枝扩散模式的网络分析表明,黄河独有的单倍型A1是一个创立者单倍型,全部青海湖裸鲤的样品来自于它的辐射,而青海湖裸鲤可能仅仅起源于黄河花斑裸鲤两个主要支系中的一个.Fs检验和核苷酸不配对分析暗示了青海湖裸鲤和柴达木盆地花斑裸鲤在历史上经历

构建和谐社会与宗教的理论审视

今年以来,本刊就“构建社会主义和谐社会与宗教”这一课题,给予了持续的关注和讨论,宗教界和宗教工作者都围绕这一主题进行了专题讨论。本期,我们主要请有关学者就这一课题发表自己的研究与见解。从各位学者的发言中,我们深切感受到了当代宗教学者的理论热情与社会关切。正如学者们所提出的:在构建社会主义和谐社会的进程中,宗教工作者、宗教界人士和学者三方,应当明确各自的职责,各扬其长,相互合作,谐调互动。诚如是,则社会和谐可期,民族复兴可待

Identification of Vibrio tubiashii isolated from diseased pond-cultured sea cucumbers( Apostichopus japonicus)

2013年春季,福建漳州地区池塘养殖刺参(APOSTICHOPuS JAPOnICuS)感染不明病原而患病。病参表现出排脏、身体萎缩、体表溃烂等症状,俗称为“腐皮综合征“。为确定引起该病的病原菌,从患病刺参病灶部位分离得到1株优势菌fJy001,经回接感染试验,证实所分离的细菌为刺参的病原菌。经形态、生理生化、16S rrnA序列分析和bIOlOg微生物自动鉴定系统等多项指标鉴定,确定该病原菌为塔式弧菌(VIbrIO TubIASHII)。In the spring of 2013,the pond-cultured sea cucumbers( Apostichopus japonicus) were infected by an unrestrained pathogen in Zhangzhou City of Fujian Province.The sea cucumbers with the disease tentatively termed as"skin ulcerative syndrome"showed symptoms such as viscera ejection,general atrophy and skin ulceration.To determine the bacterial pathogen that caused the disease,one strain( FJY001) was isolated from the lesions of diseased sea cucumbers.Pathogenicity of the strain was confirmed by artificial infection and the strain was identified as Vibrio tubiashii by indicators of morphological,physiological and biochemical characteristics as well as sequencing of 16 S rRNA and identification of Biolog microbiol system.福建省科技厅公益类科研专项(2010R1002-3); 福建省水产研究所科研发展基金资助项目(2014fjscq04

Vegetation carbon stocks and net primary productivity of the mangrove forests in Shenzhen,China

红树林是滨海湿地"蓝碳"的主要类型之一.准确和定位评估不同植物群落的固碳能力,对于红树林保育管理和恢复造林具有指导作用.本研究对深圳福田红树林4种代表性群落(白骨壤群落、秋茄群落、海桑群落、无瓣海桑群落)的各个植被碳库组分(乔木植物生物量碳库、林下灌丛碳库、呼吸根碳库、枯立木碳库、枯倒木碳库和枯枝落叶层碳库等)进行调查,计算各群落的植被碳储量,并通过生长增量-凋落物产量法计算得到各群落的净初级生产力.结果表明:白骨壤群落、秋茄群落、海桑群落和无瓣海桑群落的植被碳储量分别为28.7、127.6、100.1、73.6 t C·hm~(-2),各群落的净初级生产力分别为8.75、7.67、9.60、11.87 t C·hm~(-2)·a~(-1).位于深圳市中心的福田红树林,每年固定大气CO2高达4000 t.本研究结果将为红树林"蓝碳"碳汇功能的评估提供理论指导,并为我国红树林碳汇林建设提供依据.Mangroves are the most important coastal blue carbon sinks. The accurate estimation on the carbon sequestration capacity of plant communities would guide the mangrove conservation,afforestation and management. This study investigated the vegetation carbon stocks of dominant mangrove communities,which were Avicennia marina,Kandelia obovata,Sonneratia caseolaris,and Sonneratia apetala in Futian Nature Mangrove Reserve in Shenzhen,Guangdong Province of China.Vegetation carbon stock consisted of living trees( aboveground and belowground biomass),understory,pneumatophore,standing dead trees,fallen dead trees and litter in these communities. The net primary productivity( NPP) was calculated from the litterfall and incremental growth in the same year of each community. Our results showed that the vegetation carbon stocks for A. marina,K. obovata,S. caseolaris,and S. apetala communities were 28. 7,127. 6,100. 1,and 73. 6t C·hm~(-2),and the NPP were 8.75,7.67,9.60,and 11.8 t C·hm~(-2)·a~(-1),respectively. Therefore,acting as urban forests,Futian mangroves in Shenzhen assimilated about 4000 t CO2·a-1.These results provided guidance for mangrove blue carbon assessment,and theoretical basis for the construction of coastal carbon sequestration forests in China.国家自然科学基金项目(31270581);; 福建省自然科学基金项目(2013J01145);; 深圳城市管理局科研项目(201406)资助~

和谐社会建设背景下的红十字会功能定位——基于X市红十字会调查的思考

构建和谐社会为我国红十字会发展带来了前所未有的机遇与挑战。问题的关键在于红十字会能否根据和谐社会建设的需要进行角色调适,使功能定位更加准确合理。基于X市红十字会的调查,我们发现红十字会在服务功能上存在“大而全“、在传播功能上存在“散而浅“的问题,这淡化了红十字会的组织特色,并衍生出专业化水平不高以及社会认知度不够等问题。因此,在构建和谐社会背景下,红十字会需要进一步转变发展思路,从“大而全“走向“专而精“,充分发挥组织优势,打造核心竞争力,以获得可持续发展。厦门大学“211工程”三期建设项目“公共管理与公共政策”成果;得到X市红十字会资

As a result, their reactions tend to afford cycloaddition intermediates or products. Herein, we report a reaction of M≡C and C≡C bonds that affords acyclic addition products. These newly discovered reactions are highly efficient, regio- and stereospecific, with good functional group tolerance, and are robust under air at room temperature. The isotope labeling NMR experiments and theoretical calculations reveal the reaction mechanism. Employing these reactions, functionalized dπ-pπ conjugated systems can be easily constructed and modified. The resulting dπ-pπ conjugated systems were found to be good electron transport layer materials in organic solar cells, with power conversion efficiency up to 16.28% based on the PM6: Y6 non-fullerene system. This work provides a facile, efficient methodology for the preparation of dπ-pπ conjugated systems for use in functional materials.This research was supported by the National Natural Science Foundation of China (Nos.
