The study of migratory bird populations, quantity, dynamics have great significance.

Over the past few decades, as a result of conservation programs and environmental laws, such as the Migratory Bird Treaty Act, bird populations in North America have increased dramatically.

在过去的几十年里，由于养护计划和环境保护法，比如候鸟条约法，在北美，鸟的数量急剧增加。

Vietnam does not have the billion-plus populations of China and India. But with 84m people, it is no minnow.

越南虽不像中国和印度那样有着十多亿人口，但就8400万人口而言，它也并非小国。

The results showed that: The number of loci detected in the German mirror Carp, Japanese crucian carp and F1 were 200、207、218, and the number of polymorphic loci were 63、66、72,and the percentage of polymorphic loci were 31.5%、31.9%、33% respectively. The percentage of polymorphic loci of F1 was considerately higher than that of the parents indicating the rather great genetic variations within the 3 populations.

结果表明：在德国镜鲤、日本白鲫、F1中检测到的位点数分别为200、207、218，其中多态性位点数分别为63、66、72，多态位点比例分别为31.5%、31.9%、33%。F1多态位点高于父母本，表明它的遗传多样性和变异水平最高。

In this paper, population genetic variability and genetic structure of five populations of an important cultivation species, mirror carp ( Cyprinus carpio L.) were analyzed using 30 microsatellite loci. The observed and expected heterozygosity values, polymorphic information content and number of effective alleles ( A e were all determined.

采用30个微卫星分子标记，对5个镜鲤群体的观测杂合度、期望杂合度、多态信息含量和有效等位基因数等进行了遗传检测，根据基因频率计算遗传相似系数和Nei氏标准遗传距离，以 c 2检验估计Hardy-Weinberg平衡，以近交系数和基因流分析群体的遗传分化。

No fragments were amplified from some loci of EST-SSRs, which may suggest the loss of these loci in mirror carp genome or sequence divergence at the primer binding sites. These null alleles may result from selection because functional genes are under more selection pressure than non-encoding loci. Overall, population genetic variation is high for each of the five mirror carp, and the differentiations are also significant among populations.

3在与功能基因相关的多个微卫星基因座位上，扩增产物呈现不同程度的缺失现象，这些无效等位基因的产生可能与结构基因在育种中受到人工选择的影响较大有关。

As we all know, many societal problems like unemployment, disparity between the rich and the poor and misgovernment are caused due to the asymmetric development of city. And they have become a crucial reason for those less effectively curable societal problems, rendering a worsening public security situation and a mounting rate of crime commitment. To some extent, particularly the problem of floating populations crime commitment is so serious that it has already affected the development and stability of city.

由于城市发展的不均衡，导致了诸如：失业、贫富悬殊、管理不当等社会问题的出现，而这些没有得到有效根治的社会问题是我国治安形势恶化的主要原因，犯罪率不断上升，而城市中流动人口犯罪的问题显得由为突出，在一定程度上已影响了城市的发展与稳定。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
