演替

Key research topics related to re-establishment of sculpin species include comparing spawning ecology and early life history of each species, determining population structure, and evaluating the feasibility of live-transfer methods.

群落和生态系统水平相互影响的关键研究题目包括了解群落功能的大尺度方向性的影响，拓展目前广泛接受的大湖生态演替观点，并且决定深水鱼类依日周期在垂直方向上迁移的进化角色。

It was suggested that the self-organization and self-fertilization capacity were built up with succession, compatible to the vegetation succession principle.

群落自组织、自我施肥能力增强与植物群落演替规律相适应。

This sequence of community is termed a sere, and culminates in the climax community.

这一顺序被称为是一个演替序列，最后达到的阶段称为顶级。

Climatic climax A plant community that is in equilibrium with a stable climate.

气候顶级群落：与稳定的气候平衡的植物群落，它代表演替的顶级。

The result showed that the growth of subaerial parts of plant community isn't obviously isochronous with the seed bank. So the inherent potential of soil seed bank has important influence on the regeneration of forest and the dynamic succession of plant community.

另外，种子库中优势成分与取样地点地面植被相应层次的优势种存在较大差异，说明植物群落地上部分的发育与其它地下部分的土壤种子库的发育具有明显的不同步性，这一结果表明土壤种子库的内在潜力对森林更新及植物群落演替动态产生了重要影响。

Otherwise, the predominant components in the seed bank are different from the subaerial predominant vegetation at correspond layer.

Herbage is the principal part of the three forests both at its variety and number Especially in needle forest, the reserves of seed have distinct predominance The proportion of herbage seed in the bank are reduced, with the increasing of succession age Otherwise, the predominant components in the seed bank are different from the subaerial predominant vegetation at correspond layer.

草本植物不仅是种类还是数量上都是这三种林型土壤种子库的主体成分，特别是在针叶林中，种子储量占有十分显著的优势地位，随着演替年龄的增长，草本植物在种子库储量中占的比例有所减少。

This kind of community development is different from the succession of a natural community.

这一群落的发展和自然群落的演替是两种不同的发展方式。

But these variations were different among tile dominant species seedlings in different forest successional stages.

不同的演替阶段优势种苗木的叶绿素含量的增加或减少在量上有一定的区别。

Early successional stages are characterized by pioneer species, low biomass and often

早期的演替阶段，具有先锋物种、低生物量和低营养水平的特征。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
