然而一个同样重要的标准是，物种在随机性全球生态灾难中幸存的能力。
Yet an equally important criterion is the ability of a species to survive random global ecological catastrophes due to impacts.
一个同样重要的标准是，一个物种是否有能力在全球任一生态灾难中生存下来。
An equally important criterion is the ability of a species to survive random global ecological catastrophes due to impacts.
一个物种生存下来的标准是它能否成功地与其他物种竞争并适应缓慢变化的环境。
The standard criterion for the survival of a species is its success in competing with other species and adapting to slowly changing environments.
根据这一定义，区分不同物种的标准是不同物种的个体间相互交配产生可育后代的可能性。
According to this definition, one species is distinguished from another by the possibility of matings between individuals from each species to produce fertile offspring.
按照我们的分类标准，仅是本世纪的头十年，我们就发现了大约300种哺乳动物新物种——大部分是啮齿类，也有有袋类，突吻鲸类以及大量的灵长类动物。
Even within our own class, mammals, roughly 300 new species have been discovered in the first decade of this century-mostly rodents, but also marsupials, a beaked whale and a slew of primates.
“理解保护策略的制订标准很重要，”库恩说道，“当然，对于许多物种来说，这种古老的基因信息派不上什么用场。”
“Understanding the baseline from which to assess conservation strategies will be important,” says Kuhn. “Of course, for many species, this type of ancient genetic information isn't available.
这种关闭基因的技术称为rna干扰(RNAi)，目前已成为控制各物种中基因活性的一个标准方法，并在2006年获得了诺贝尔奖。
Called RNA interference (RNAi), the technique has become a standard way to control gene activity in a variety of species, earning a Nobel Prize in 2006.
在现实世界中，此标准可能难以应用到相距遥远的种群，由地理环境分隔的种群，或是植物种群（化石显然也无法繁殖）。
Inpractice, this standard can be difficult to apply to organisms isolatedby distance or terrain or to plants (and, of course, fossils do notbreed).
至2008年IUCN评估的44 838个物种中，16 928种至少符合“面临高度灭绝危机的野生物”的标准。
Of the 44, 838 species that the IUCN had evaluated by 2008, 16, 928 met at least the criteria for “facing a high risk of extinction in the wild.”
我们证明隔离片的微生物回收比标准培养的回收要超出数倍之多，已成长的物种也产生大量的新物种。
We show that microbial recovery in the ichip exceeds manyfold that afforded by standard cultivation, and the grown species are of significant phylogenetic novelty.
小龙门林场及毗邻地区的天然植被保存良好，结构合理、物种丰富，在进行森林健康评价时，可作为健康标准的参考之一。
Natural vegetation in Xiaolongmen and adjacent areas can be used as the reference standard of health assessment for they are preserved well, have rational structure and rich species.
新物种已被其他人发现并确定下来，所使用的评估物种的标准也更广泛地适用于所有的动植物。
New species have been identified, others discovered, and the criteria used to assess species have been made more broadly applicable across all animals and plants.
新物种已被其他人发现并确定下来，所使用的评估物种的标准也更广泛地适用于所有的动植物。
New species have been identified, others discovered, and the criteria used to assess species have been made more broadly applicable across all animals and plants.
