鸟类

Result, former the gray kind that go to bed gets protective on lichen, be in at this moment black is truncal on easy however by avian prey; And black type criterion because of fuliginous covering spare avian prey to get live and developing instead.

结果，原先歇息在地衣上得到保护的灰色类型，这时在黑色树干上却易被鸟类捕食；而黑色类型则因煤烟的掩护免遭鸟类捕食反而得到生存和发展。

Till the end of 2006,5 859 site records of all 63 species of Chinese Galliformes and 1 027 literature resources were collected in the database.

本数据库的物种信息有助于加深对我国鸡形目鸟类资源的了解，可为中国鸡形目鸟类的研究和保护提供翔实的基础数据。

The birthplace of migrating birds had been a controversial problem for a long time. Based on comparision within winter habitat, reproduction habitat of Grus nigricollis, reproductive physiology and the upheaval of Qingzang Plateau in the Quaternary Period. We concluded that reproductive habitat was the birthplace of the bird species.

迁徙鸟类的种系发源地一直是个有争议的问题，本文依据黑颈鹤的越冬生境与繁殖生境的对比，以及青藏高原隆升与第四纪冰川的先后、动物繁殖生理等不同证据推断，繁殖地是鸟类迁徒的种系发源地。

It is the black stork Yesanpo found the largest number of first time. With Yesanpo scenic ecological environment increasingly improve and villagers on wildlife protection consciousness enhanced here every year White Swan, Grus, black stork other large birds emergence year round all OK Watch to rare birds figure .

据景区工作人员介绍，随着野三坡景区生态环境的日益改善和村民对野生动物保护意识的增强，这里每年都会有白天鹅、灰鹤、黑鹳等大型鸟类出现，一年四季都可以观赏到珍稀鸟类的身影。2000年至今，黑鹳出现的次数最多，但是每次也就四五只。

The reason is that bird distribution from heterogenic to homogenic with the increasing scale, so the attributions of the habitat. On the another hand, the value of H is increasing with increasing of the encounter ratio among the bird.

分析这一现象，说明随着尺度的增加，生境斑块异质性增强的同时，鸟类的分布则由异质性转换成均衡分布，与此同时，随着鸟类的遇见率增强，其多样性指数也随着升高。

We diided 157 bird species showing regular intercontinental moements into four groups based on patterns of moement-one of these groups (breed Holarctic, winter Eurasia) fits well with the design of the monitoring programs i.e., western Alaska

我们检查了洲际间鸟类的迁徙，将157种鸟类物种分类表明，有规律的洲际迁徙有四组，基于这种迁徙模式我们能够很好的设计监测体系。

The imitable sounds of a bird.large aquatic birds: loons and some extinct forms.

大型水生鸟类；潜鸟及其它一些已绝迹的鸟类。

The answer, says Dr Kroo, lies with birds. Since 1914, and a seminal paper by a German researcher called Carl Wieselsberger, scientists have known that birds flying in formation—a V-shape, echelon or otherwise—expend less energy.

克鲁教授称这个设想是受到鸟类的启发。1914 年，一位名叫卡尔维塞尔斯伯格的德国研究员发表了一篇具有重大意义的论文，科学家们从中得知，鸟类在飞行的时候排成 V 字，梯形或倒过来时，会节省体力。

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。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
