群落

Long temporal controlled field study with herbivorous animal is essential to investigate the productivity and stability of plant community.

群落稳定性的生态学研究一直缺乏动物利用条件下的长时间梯度田间试验，而混播草地的放牧利用年限是生态脆弱的南方喀斯特山区生态环境建设和资源可持续利用的关键问题之一。

The museum's research and collections activities are carried out by its scientific divisions. Some divisions have web sites, and click on the name of the division to go to the web site, such as botany, community ecology, entomology, Herpetology, Ichthyology, Histology Lab etc.

它的研究和收集活动都是由它的各个科学部门完成的，一些部门有自己的网站，可以通过点击它们的名字到达相应的网站，例如：植物学、群落生态学、昆虫学、两栖爬行类学、鱼类学、组织学实验室等。

Honeybee populations in many countries, including the United States, appear to have declined markedly in recent years.

In some eusocial Hymenoptera, workers can produce male offspring from unfertilized eggs.

然而，此前人们不知道工蜂能够在其同一物种的其他群落中寄生生育后代。

In the action of Dimilin, the diversity levels of Lepidoptera and Orthoptera insect of the treatment plot had a certain degree decline, and the diversity degrees of Hymenoptera insect and spider had a large increase, thus insect community in the treatment stand tended to be relatively stable.

在时间过程中，施药区鳞翅目和直翅目昆虫的多样性水平有一定程度的下降，但下降程度不如对照区大，膜翅目和蜘蛛的多样性水平则有较大程度的上升，因此林内昆虫群落趋于相对稳定。

The differentiation of inner structure of plantations after the canopy completely closure at about 30 yr, reflected the dynamics of the interact of self-thinning and species inbreaking of outer communities.

人工林在30年左右冠层完全郁闭后，群落内部的结构进一步发生分化，体现了自疏过程和外来物种侵入相交织的动态过程。

The result showed that these indic es could effectively reveal the characteristics of species composition for sub-tro pic shrubs.

结果表明：这3种指标能够有效地表征亚热带灌丛群落的组成结构特征。

Cities and countryside are the main inhabitation communities for human being.

城市和农村是两种主要的人类居住群落。
