查询词典 Passeriformes

With the support of the project, the study completed the classification to passerine birds in Yunnan, summarized their habitat environment, geographical distribution; and analyzed the characters and evolution tendency of avifauna in Yunnan, geographical division of birds in Yunnan. The project was successfully completed. As production of the study, the book of "The avifauna of Yunnan China, Vol.2: passeriformes", three articles in periodical journal, two articles in national meeting proceeding and three articles in international meeting proceeding were published.

在该项目的支持下，通过对云南省雀形目鸟类的分类整理工作，以及栖息地生境、地理分布、区系组成和演化、地理区划等总结分析，完成和出版了《云南鸟类志下卷雀形目》，发表期刊论文3篇，国内学术会议论文2篇，国际学术会议论文3篇。

By employing two kinds of molecular marker of mitochondrial DNA, i. e. Cyt b and CoI gene, the sequences of 15 species representing 6 families from Passeriformes were compared. We analysed their sequences compose and characteristic with the sorft of MEG3.1, and built the phylogenetic trees in PAUP~*4.0. We deeply analysed the feasibility that CoI gene qua the marker to research the phylogenetic relationship of Passeriformes, and afford the academic proof for building the DNA barcoding of the birds.

本文分别以线粒体DNA的细胞色素b和CoI基因作为分子标记，对雀形目6科15种鸟类的细胞色素b基因全序列(1，143bp)和CoI基因部分序列(1，176bp)的组成特点及其系统发育树进行了比较分析，还探讨了CoI基因作为雀形目系统发育研究和构建鸟类物种DNA编码库的分子标记的可行性，旨在为DNA编码库的构建积累基础资料。

From May to June 2001~2005 (except 2003), in the Honghuaerji area of Inner Mongolia, sampling method was applied to investigate the Bird Communities Structure of Grassland-Forest Ecosystems, Results indicated that:(1)In the Honghuaerji area, Passeriformes, Charadriiformes and Anseriformes were main birds, in summer reproducing season.

2001～2005年5～6月(除2003年)，在内蒙古红花尔基地区，应用样方调查法研究了草原-森林生态系统鸟类群落结构，结果表明：(1)在红花尔基地区，夏季繁殖季节鸟类组成是以雀形目、鸻形目和雁形目为主。

Used in some classification systems; a suborder or superfamily nearly coextensive with suborder Tyranni; Passeriformes having relatively simple vocal organs and little power of song: clamatorial birds.

用于某些分类中；几乎与霸鹟亚目同延的一个亚目或亚科；有相对简单的发音器官和较差的鸣唱能力；叫禽类鸟。

Moreover, CoI gene was more conservative and a lower evolutionary rate than Cyt b gene. CoI gene was an effective marker in analysing the phylogenesis of families in Passeriformes. It can be used in identifying the species of Passeriformes, but it was revealed that CoI gene was more suitable to identify the phylogenetic relationship of avian family unit than Cyt b gene, and CoI gene can be a molecular marker to identify avian species. But in species identification, CoI gene was less stable and accurate than Cyt b gene. We suggested youd better employ the other marker if you have the CoI gene only.(2) In the phylogenetic trees of birds from Lanius, L.

比较分析了雀形目6科15种鸟类的细胞色素b全序列和CoI基因部分序列，结果显示细胞色素b和CoI基因序列的变异位点分别为454个和366个、简约信息位点为337个和303个，而且线粒体CoI基因比细胞色素b基因略微保守、进化速率也较低；CoI基因在确定雀形目科级阶元之间的系统发生关系方面是一种有效的分子标记，同时它也能够用于雀形目鸟类的物种鉴定，但在物种鉴别方面不如细胞色素b基因稳定、准确。

Densities of several species of passeriformes are affected by reed cutting.

雀形目鸟类的密度分布受芦苇割伐的影响，在配对和营巢活动前，有一个&自然稀疏&的行为效应，这是种内和种间密度过高的结果。
