In order to the conservation and utilization of this wasp, laboratory studies were conducted to assess the population dynamics of them and effectiveness of the long-winged parasitoid wasps, T. elegans for suppressing populations of S. oryzae using methods for single element variance analysis and LSD multiple comparisons.

为了更好地保护和利用该蜂，采用单因子方差分析和LSD多重比较，在实验室内研究了雅脊金小蜂和米象的种群数量动态，以及该蜂长翅型雌蜂对米象种群的控制作用。

By fingerprinting two of Mute Swan populations in Britain with HaeⅢ and pSPT19.6,it has been found that interpopulation variation is greater than intrapopulation variation ,and that the variability of minisatellites is higher in Lothian population than that in Abbotsbury population with regard to the Mme Swan.

用酶HaeIII和探针pSPT19.6分析了分布在英国的疣鼻天鹅种的两个群体(洛锡安群体和阿伯茨伯里群体)的DNA指纹图，结果表明两群体之间的遗传变异性大于群体内的遗传变异性；洛锡安群体内小卫星的变异程度较高。

Low Nucleotide diversity indicated that genetic differentiation coming from the same origin was relatively low, and may be have a recent common ancestry for the populations.

较低的核苷酸多态度表明，同一起源的家鹅mtDNA群体分化程度较低，它们拥有较近的共同祖先，且可能是在不同的时间多个中心由鸿雁野生种驯化而成。

In this issue of Journal of Clinical Oncology, Kilbridge et al6 expose another dimension to the complexity of caring for and performing research in low-literacy populations.

在这一期的《肿瘤临床》中，Kilbridge等人从另一个角度揭示了对文化水平低的患者进行治疗和研究的复杂性。

The study by Kilbridge et al illustrates that many of the words that are used in clinical and investigative settings are not well understood by low-literacy populations. Many of these misunderstood words are used in long-established measures, such as those assessing quality of life.

他们指出：医生和调查机构的许多词汇对于文化水平低的患者来说就如天书一般不知所云，而许多这些被误解的词汇都是被用在一些早已确定的研究方法，例如生活质量的评价方法之中。

For example, randomized clinical trials of low-literacy directed interventions have resulted in marked improvements in colorectal cancer screening rates among low–health-literate populations.37,45 We have also recently seen the increase in various patient navigator programs around the country.

例如，我们专门为文化水平较低的患者制定的随机临床实验已经显著提高了其接受结直肠癌筛查的比例，又比如我们全国范围内的领航项目的参与人数也越来越多。

It can be concluded from the experiment results that hatchery seed has lower genetic variation and large-scale hatchery seed releasing affects the genetic diversity of the natural population. The shrimp distributed along China coast in Bohai Sea and Yellow Sea may consist of more than one populations. The viral disease resistant ability of F. chinensis is proved to be genetically inherited and can be improved by genetic selection.

通过对实验结果的进一步分析认为：中国对虾人工育苗的过程使后代群体的遗传多样性下降，人工培育苗种的大规模放流影响了自然群体的遗传多样性；，分布于我国沿海的中国对虾可能由多个自然群体构成，还存在未被发现的种质资源；中国对虾抗WSSV病毒感染是由遗传决定的，选育可提高中国对虾对WSSV的抗性。

The central Lowlands are the most important are in Scotland, which contains most of the industry and populations.

其中，中部低地是苏格最重要的地区。

Comparing with the populations of Canton,Kunming ,Sanhutan,Sumoto, and Kuala Lumper,we come to the conclusion that D.albomicans caught in Shanghai and areas nearby is from a few of places in the south of China-mainland.

在与广东、昆明、台湾珊瑚潭、日本洲本及马来西亚吉隆坡群体比较后，我们认为上海及邻近地区突然发现的D.albomicans来自中国大陆南部的多个群体。

But as European rabbit populations continue to decline due to disease, so do lynx.

但是随着欧洲兔子的数量在持续减少，伊比利山猫的数量也随之减少。

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).
