生物生态学

In the past tens of years, a lot of studies have been done to investigate the influences of Allee effects on population dynamcs, species interaction, conservation, species range expansion and alien species invasion.

近几十年来，人们开展了大量的理论和实验研究探索Allee效应对种群动态、种群间相互作用、生物保护、物种扩张和外来种入侵等生态学过程的影响。

But the resources competition theories in earlier period have mainly come from chemostat model. Up to 90\'s in 20 centuries, a large numbers of species inhabit patchy environments due to fragmentation of landscape resulting from unreasonable economic activities by man.

到了20世纪90年代，由于人类不合理的经济活动造成景观格局的破碎化，使得大量的物种栖息于斑块状的环境中，于是生态学的理论中出现了岛屿生物地理学和集合种群的概念。

Behavioral ecologists study the behaviours of individual organism s as they react to their environment.

行为生态学研究生物个体的行为，包括取食技术、对掠食的生存适应、交配以及对环境变化的应答等。

Physical, chemical and biological agents were main elicitors being applied, which can change morphology, physiology and biochemistry to improve the natural disease resistance.

能够有效诱导果蔬采后抗病性的因子主要有物理、化学、生物等，其机理是通过生态学和生理生化的变化来提高果蔬对病原菌的抗病性。

Therefore,a new subject,urban forest ecology,and correlative new concept frame in the field formed.

城市森林生态学的形成使人们从生态系统的角度审视城市的发展，并把生物环境即人类及所有植物和动物的群体视为这个系统的一个要素，引出了&城市森林&的概念。

Major subject areas covered include: Molecular biology; Cell biology; Plant physiology; Anatomy and morphology; Biotechnology; Agronomy and horticulture; Forestry; Plant pathology; Ecology; Taxonomy, systematics and evolutionary studies; Flora reports and plant geography and so on.

主题范围包括：分子生物学、细胞生物学、植物生理学、形态解剖学、生物工程学、农学和园艺学、林学、植物病理学、生态学、分类学、系统和进化研究、植物志和植物地理学等等。

Comparison with the prevail methods on the bird community, the bird dates were ordinated after clustering the bird into different type to avoid redundant species to the result biodiversity and ordination and there are the reasons

群落内物种组成及其功能是群落生态学研究的基础和重点，而任何生物又都是其生境的一部分，共同构成一个整体，其生存和发展必然受生境所制约。

In this paper, based on the review of many kinds of literatures and field survey in Dong Minority located in Congjiang County of Guizhou Province, the background of taboo formation was analyzed, some typical taboos related to rice-planting such as god and ghost worship, ancestor worship, and water worship, fish worship, frog worship, snake worship and so on, and their significance were discussed from the ecological angle, and the positive effects of traditional cultures including taboo in ecological conservation and regional sustainable development were illustrated.

在大量文献调研和实地考察的基础上，以黔东南侗族地区为例，较为系统地研究了一些禁忌产生的原因，重点分析了稻作文化中的一些禁忌及其生态学意义，揭示了少数民族地区包括禁忌在内的传统文化对生态保护和生物多样性保护的积极作用。

Energy budgets were obtained and the ecophysiological mechanisms of fish regulating its energy allocation were discussed. These results can provide basic data for the study of fish bioenergetics and fish culture.

得出了该鱼的能量收支式，并探讨了鱼类调节其能量分配的生理生态学机制，为鱼类生物能量学和养殖生产提供基础资料。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
