濒危

The protection measures were proposed based on the discussion of the status and trends of the population viability. The results will enrich the studies on conservation of endangered plants, and improve the cross researches of population ecology and conservation biology, and provide the scientific guidance for conservation of Cycas fairylakea population.

研究结果不仅丰富和发展了珍稀濒危植物保护研究的理论和方法；而且有利于种群生态学和保护生物学交叉领域研究的进一步深入；同时为仙湖苏铁种群保护对策的制定以及保护行动的开展提供了科学依据和方法指导。

Investigating the ecology environment and present situation of the endemic Cycas plants to Yunnan, especially the population structure and dynamics of C. Hongheensins and C. tanqingii. The results show that C. hongheensis is a critically endangered species because the number its individuals had decreased by 47% from 1992 to 2002 and no flowering and fruiting tree has found. While the population of C. tanqingii in Xiaoheijiang River is in a status of restoration because there are more young individuals and its age structure takes on the relatively stable shape of pyramid.

对云南苏铁属特有植物的生态环境、现状等进行了较为全面的调查，特别是对红河苏铁、潭清苏铁的种群结构和动态进行较为详细的调查，结果表明红河苏铁是一个极度濒危的种，2002年的个体数量比1992年减少了47%，连续3年的调查未发现具繁殖能力的个体；而潭清苏铁种群的年龄结构基本呈金字塔形，属较稳定的结构，且处于恢复期，繁殖更新基本正常。

Currently, many law-breakers keep killing animal in danger only for money and this makes more animals go to extinction.

现在，有许多的不法分子面对金钱，依然猎杀濒危动物，使得越来越多的动物走向毁灭。

The moving force behind the snail darter's sudden fame came some four months after its discovery, when the Congress passed the Endangered Species Act of 1973, 87 Stat.

在蜗牛镖发现并声名鹊起的四个月后，美国国会通过了1973年《濒危物种法》。

Shortly after the Act's passage the Secretary was petitioned to list a small fish popularly known as the snail darter as an endangered species under the Act.

在该法通过后不久，有人请求内政部长依据该法将一种名为蜗牛镖列为濒危物种。

The court held that the record revealed a prima facie violation of 7 in that the Tennessee Valley Authority had failed to take necessary action to avoid jeopardizing the snail darter's critical habitat by its "actions."

上诉法院认为，从表面上看，有关记录显示田纳西流域管理局违反了《濒危物种法》第七条，因为田纳西流域管理局没能在其行动过程中采取必要措施使蜗牛镖关键性栖息地免受危害。

The Court of Appeals reversed and [437 U.S. 153, 154] ordered the District Court permanently to enjoin completion of the project "until Congress, by appropriate legislation, exempts Tellico from compliance with the Act or the snail darter has been deleted from the list of endangered species or its critical habitat materially redefined."

因此，地方法院判道："在一个联邦工程项目即将完工而又无法改变的情形下，衡平法院不应当适用一部在工程开工之后很久才颁布的法律去导致一个不合理的结果……"上诉法院推翻了地方法院的判决，并要求地方法院永久禁止该工程项目完工，"直到国会通过适当的立法免除泰利库工程项目遵从此法的义务，或者蜗牛镖被从濒危物种名录剔除，甚或其关键性栖息地被实质性重新认定。"

But, rather as John Maynard Keynes observed that "there is no subtler, no surer means of overturning the existing basis of society than to debauch the currency," so Linnaeus's system is being subtly debauched by over-eager taxonomists, trying to help conservation.

如今，过份热情的物种分类学家，尽管是出于挽救濒危物种的好意，却在不知不觉之中让林纳斯的体系贬值了。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
