种群比较

We are focused on the Glanville Fritillary. With the comparison of the study in Finland , the effect on metapopulation ecology and adaptation of the Glanville Fritillary in different level of habitat fragmentation are studied.

本研究组以庆网蛱蝶为主要研究对象，通过和芬兰庆网蛱蝶种群的比较研究，探讨不同片段化程度下集合种群结构动态及其影响因素，从而分析栖息地片段化对庆网蛱蝶的影响，以及庆网蛱蝶的适应机制。

By integral in mean and comparison theorem, boundednesses of consumer population and resources, as well as a sufficient condition for population's weak persistent in mean are given when the environment is with a small capacity.

利用积分均值法和比较定理，给出消费者种群和资源量的有界性，以及环境容量较小情形下种群弱平均持续生存的充分条件。

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。

The research areas of the Department include: Comparative ecology, physiology of plant populations, ecosystem science, community ecology, population biology, evolutionary genetics, macroevolution and systematics etc.

该系的研究领域包括：比较生态学、植物种群生理学、生态系统科学、群落生态学、种群生物学、进化遗传学、宏观进化和系统分类学等。

No significant genetic differentiation was displayed among rotifer clonal groups in three lake districts of Donghu Lake.

因此在武汉东湖萼花臂尾轮虫种群是由遗传距离较大，分布比较随机的克隆群组成的，种群在各湖区无明显分化。

In this investigation, the number of maternal ramets and daughter ramets, length of stolon and spacer, distributed pattern of spacer and the relationship with community quantitative character were compared and researched between the two Potentilla. This offers basic data for more discussions to ecological and phenotypic adaptive strategy of the two population.

本文就两种委陵菜种群的母株、分株数量、匍匐茎长度以及间隔子长度及其布局及其与群落数量特征的关系进行比较研究，为进一步深入探讨这两种委陵菜种群的表型适应与生态适应策略提供基础性研究数据。

However, the population genetic structure of Alectoris species using the microsatellite DNA data was very scarcely.

本文利用微卫星DNA标记，研究它们的种群遗传结构。目的在于(1)比较两种石鸡各种种群间的遗传差异，重建系统发育关系。

Applying the boundness and some propertities of the mean of integration, we get the sufficient condition of weak persistence in the mean, and the curve of demarcation between weak persistence in the mean and going-to death.

本文利用比较原理证明系统解的有界性，由解的有界性及积分均值的一些性质得到了种群弱平均持续生存的充分条件，并在一定条件下得到了种群弱平均持续生存与绝灭之间的分界曲线。

Applying the boundness and some propertities of the mean of integration, we get the sufficient condition of weak persistence in the mean, and the curve of demarcation between weak persistence in the mean and going-to death. An optima!

本文利用比较原理证明系统解的有界性，由解的有界性及积分均值的一些性质得到了种群弱平均持续生存的充分条件，并在一定条件下得到了种群弱平均持续生存与绝灭之间的分界曲线。

The main results are listed as following: 1. Phylogeographic study on Croomia The relationships and distribution of cpDNA haplotypes suggested that Croomia had been widely distributed in ancient eastern Asian and northern American; the origin and distribution center of Croomia were concentrated on the mountains comprised Mt.

Croomia亲缘地理学根据叶绿体DNA(trnL-F、atpB-rbcL)单倍型的关系和分布推测，Croomia在古欧亚大陆和古北美大陆有着较广泛的分布；我国的黄山和天目山一带是Croomia的分布、起源中心，其散布路线是从中国大陆到日本，再到美洲古大陆；北美种群与东亚种群分离较早；东亚种的分化时间比较晚。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
