【TPO例句】

1. And these nutrients promote diversity in the stream environment. (TPO52-L2)

这些营养物质会促进溪水环境的多样性。

2. In a fragmented landscape where many populations and habitats are isolated from others, translocations can play an effective role in conservation strategies; they can increase the number of existing populations or increase the size, genetic diversity, and demographic balance of a small population, consequently increasing its chances of survival.(TPO37-P2)

在一个四分五裂的大陆上,不同的种群和栖息地是彼此隔绝的,这时候作为保护措施的物种迁移就起到了重要的作用;他们可以促进动物数量增长,帮助种群规模扩大,增加基因多样性,平衡小种群的数量,最终增加动物的存活率。

3. Additionally, translocation of predators or competitors may have negative impacts on other species, resulting in an overall loss of diversity. (TPO37-P2)

另外,捕食者或者竞争者的迁移也许会对别的物种产生不好的影响,导致多样性的整体减少。

4. Although the Aegean had been the birthplace of marine biology, its depths are now known to be exceptionally lacking in animal diversity.(TPO36-P2)

即使爱琴海是海洋生物学的起源地,它的全部深度范围里的生物种类也是有限的。

5. So from fewer, simpler and relatively similar forms of life billions of years ago, life on Earth has now become a dazzling array of diversity and complexity.(TPO39-L1)

所以从十亿年前数量少的、简单的和相对来说更加相似的生命形式,地球上的生物现在变成了一群有巨大多样性和复杂性的群体。

6. Well, some geologists now want to apply this concept to explain mineral diversity too. (TPO39-L1)

一些地质学家现在想把这个理论应用到解释矿物质多样性上。

7. Their diversity of coral genera is greatest in the warm waters of the Indian Ocean and the western Pacific. (TPO47-P3)

在印度洋和西太平洋的温暖水域中,珊瑚属的生物多样性是最大的。

8. Three mechanisms by which higher diversity increases ecosystem stability have been proposed. (TPO46-P3)

有人提出,物种的多样性透过三种机制增加了生态系统的稳定性。

9. One of the first studies to provide data supporting a relationship between diversity and stability examined how grassland plants responded to a drought. (TPO46-P3)

最早提供数据来支撑多样性和稳定性之间的关系的是一项关于草原植物如何对抗干旱的研究。

10. The Minnesota grassland research has been widely accepted as strong evidence for the diversity- stability theory; however, its findings have been questioned, and similar studies on other ecosystems have not always found a positive relationship between diversity and stability. (TPO46-P3)

明尼苏达草原的研究作为多样性-稳定性理论的有力证据已被广泛接受,但是,它的研究结果已经被质疑,另外其他生态系统的类似的研究并没有找到多样性和稳定性之间积极的相关性。

11. When we look at the way in which biodiversity (biological diversity) is distributed over the land surface of the planet, we find that it is far from even. (TPO40-P2)

当我们在研究生物多样性在地球表面的分布方式时,我们发现这种分布是很不均匀的。

12. The tropics contain a larger surface area of land than higher latitudes - a fact that is not always evident when we examine commonly used projections of Earth’s curved surface, since this tends to exaggerate the areas of land in the higher latitudes - and some biogeographers regard the differences in diversity as a reflection of this effect. (TPO40-P2)

热带地区比高纬度地区土地面积更大——当我们在审视通常所用的地球曲面投影时,这一事实并不总是显而易见的,因为这往往夸大了高纬度的土地面积——一些生物地理学家认为物种多样性的差异反映了这一点。

13. The high plant biomass of the tropics leads to a greater spatial complexity in the environment, and this leads to a higher potential for diversity in the living things that can occupy a region. (TPO40-P2)

热带地区庞大的生物量导致了环境的更大的空间复杂度,也就使得住在这个区域的生物的多样性可能更高。

14. The climates of the higher latitudes are generally less favorable for the accumulation of large quantities of biomass; hence, the structure of vegetation is simpler and the animal diversity is consequently lower.(TPO40-P2)

高纬度地区的气候条件一般不利于大量生物的集聚,因此,植被结构更简单些,动物的多样性也相应较低。

15. This is particularly important for species that colonize an environment where there is no existing vegetation to ameliorate climatic extremes and in which there may be great climatic diversity.(TPO32-P1)

这对于要迁居到没有植被去改善极端气候和已具备气候多样性的地方的物种尤其重要。

16. When burning occurs, it prevents competition among plant species from progressing to the point where some species exclude others, reducing the overall diversity of the ecosystem. (TPO31-P3)

焚烧的发生防止了植物之间的竞争,这就避免了因植物间的排挤而减少整个生态系统的多样性。

17. On the bright side, in all the research being done on causes, we have discovered something related to how starfish populations might affect coral reef diversity. (TPO31-L3)

从好的一面来看,在所有关于原因的研究中,我们已经发现了一些关于海星数量可能怎么影响珊瑚礁的多样性的。

18. So without the outbreak, the diversity of coral would be reduced. (TPO31-L3)

所以,如果没有数量的激增,珊瑚的多样性就会减少。

19. Pedodiversity is basically soil diversity. (TPO29-L1)

土壤多样性指的就是土壤的多样性。

20. It generally has more diversity. (TPO29-L1)

大体上,它更加多样性一点。

21. When sea stars are removed, species diversity falls sharply. (TPO27-P3)

海星被移除后,物种多样性大幅度降低。
