The 54 accessions were classified into five major groups:Ⅰ,Ⅱ,Ⅲ,Ⅳ and Ⅴ by cluster analysis using UPGMA, which showed significant relationship with the origin regions of accessions. Genetic differentiation between and within eight eco-geographical groups of C.dactylon was estimated by Shannon's diversity index, which showed that 63.81% genetic variance existed within group, and 36.19 % genetic variance was among groups, indicating rather large genetic distances among those germplasm, and there was a correlation between genetic differentiation and eco-geographical habits among the groups.

聚类分析结果表明，52份材料可聚为5类；基于Shannon多样性指数估算了8个狗牙根生态地理类群内和类群间的遗传分化，类群内的遗传变异占总变异的63.81%，类群间的遗传变异占总变异的36.19%，表明这些抗源材料遗传差异较大，各生态地理类群间的遗传分化与其所处的生态地理环境具有一定的相关性。

Greater Brown Wren Warbler and yellow-bellied Wren Warbler (P.flavive-ntris) are the sympatric species pair in south China.In this paper,the interspecific niche relationship between the two bird species was studied.

本文研究了褐头鹪莺和黄腹鹪莺(P.flaviventris)在取食高度、取食基层和取食方法3个生态维度上的生态位宽度和生态位重叠以及它们与复合种群密度的关系。

In fact, CA ecology and political environments arecoordinated in emerge and motivation. Traditional accusatorial action and originaldemocracy are coordinated; traditional inquisitorial action and dictator-type system arecoordinated; modern CA and modern politic systems are coordinated.

实际上，刑事诉讼生态与政治环境保持着共生、互动与协调的生态平衡关系：传统弹劾式诉讼与原始民主政体是协调的；传统纠问式诉讼与专制集权政体是匹配的；而现代刑事诉讼生态与民主宪政体制则极为和谐一致。

From the viewpoint of history, the certain CA ecology and themainstream ethic habit and moral rules are coordinated: Traditional accusatorial actionecology adapts the ancient society ethic habit; Traditional inquisitorial action ecologyadapts the grade ethic rules.

从历史发展来看，特定的刑事诉讼生态与社会主流伦理习惯和道德准则是协调一致的：弹劾式诉讼生态适应了古代社会伦理习俗的基本要求；而纠问式诉讼生态必然与奉行等级伦理秩序的道德法则相配套；近代刑事程序改革主题就在于体现了古典自然法道德原则对于人性尊严和人的权利自由的充分确认。

This weed population had a wider niche breadth, the second widest among 12 major weed populations in weed community, and had bigger niche overlap with Stellaria alsine, Alopecurus acquallis, Malachium aquaticum, Poa annua, Polygonum persicaria and Lapsana apogonoides. In rape, wheat or fallow, B.

在杂草群落中，草的生态位宽度居第2位，说明其有潜在的较强的适应环境的能力；草与雀舌草、看麦娘、牛繁缕、早熟禾、春蓼和稻搓菜等杂草种群的生态位重叠较大，与它们的生态要求比较接近。

The journal established in 1991, focuses on the field of macroecology: the study of broad, consistent patterns in the ecological characteristics of organisms and ecosystems, including studies addressing general ecological hypotheses, exploring and testing using data of broad geographic, taxonomic, or temporal scope; studies documenting ecological and biogeographic patterns, theoretical studies exploring the causes of those patterns, applied studies of impacts of anthropogenic influences, as well as methodological studies of the tools used to study these problems; broad-scale patterns of biodiversity, ecosystem responses to global climate change, historical and evolutionary biogeography, remote sensing of ecosystem properties, species abundance and species range patters, and statistical methodologies.

杂志创刊于1991年，主要致力于大生态学：生物体的生态学特征和生态系统广泛一致的研究，包括介绍普通生态学假设，通过地理学，分类学，或有限范围内的数据探索和试验的研究；验证生态学和生物地理学模式的研究，探索这些模式原因的理论研究，人为影响的应用研究，以及用于研究这些问题的工具的方法学研究；大尺度生物多样性模式的研究，生态系统对全球气候变化的反应，历史和进化生物地理学，生态系统的遥测，物种的丰度和物种变化模式，以及统计学方法论。
