鸟类的

Pound for pound, one parasite—the trematode fluke that infects a certain snail—outweighs all of the estuaries' birds, which are the ecosystem's top predators.

在相同的换算标准下，一种感染特定蜗牛的吸虫的重量就要超过这些生态系统中鸟类的总和，虽然鸟类位于生态系统的顶端。

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。

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。

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。

Of or relating to birds of the order Passeriformes, which includes perching birds and songbirds such as the jays, blackbirds, finches, warblers, and sparrows.

雀形目的雀形目的鸟类的或与雀形目鸟类有关的，包括栖木类鸟和鸣鸟如松鸦、燕雀、呜禽和麻雀

The main factors that influence grassland bird nest-site selection are the height and density of herbage, and the density of Armerniaca sibiric.

草原鸟类的巢址选择中存在资源分割，影响草原鸟类巢位选择的主要因子是草本植物的高度和密度、蒙古山杏的密度。

Cluster analysis was used to understand the community structare of Tragopan temminckii and the interspecific relationship between this pheasant and other birds.

1994～11～1995－9我们在四川卧龙自然保护区进行红腹角雉的野外生态研究，主要通过聚类分析的方法分析了红腹角雉与所在鸟类群落的其他鸟类的种间关系。

He and Nina moved to California and lived at 2005 Ivar Street, Apt.

他和Nina搬到加州，并在2005年伊瓦尔街，公寓生活。

Droperidol （ potently inhibits transfected HERGchannels and this is the probable mechanism for QT prolongation.

氟哌利多有效地抑制了转染的 HERG 钾通道，可能是 QT 间期延长的机制。
