So, we can study individual species through population ecology.

因此，我们可以通过种群生态学来研究单个物种。

They morphed from this undifferentiated sea of green into individual species with individual characters.

She also says different methods of flight mean different resource demands for individual species.

If it can figure out how to tease out more individual species types, this survey method might really click.

如果这项技术能辨别出更多物种，那这种调查方法可能真的会奏效。

But since the days of Darwin, scientists have figured that individual species of birds should not have both

If we keep doing this, eventually, we can get down to individual species and be able to easily tell them apart.

Other biologists in the 19th century, had noticed this pattern in individual species, but Thayer went much further, extended his idea to all kinds of animals.

More interesting was the fact that almost half of the molecules measured in blood also showed an association with the gut microbes, with microbial functions carried out by microbial teams showing eightfold more associations than individual species.

更有趣的是， 几乎一半在血液中测量的分子也显示出与肠道微生物的关联， 微生物团队执行的微生物功能显示出比单个物种多八倍的关联。

As is so frequently the case, there is a special exception regarding the word fishes, which you may have heard before, and fishes is a word that we would use when we're talking about individual species of fish.

通常情况下， 关于鱼这个词有一个特殊的例外，你可能以前听说过， 当我们谈论个别鱼类时， 鱼是我们会使用的一个词。
