So in this case there's across-protection mutualism between these two species in which they help to avoid predation.

“因此在这种情况下这两个物种就互惠共生关系。”

Within the rainforests, diverse plant and animal species created  unique ecological communities.

在雨林中，多种多样植物动物物种独特生态群落。

All of the species that fall off will form a clade.

所有脱落物种都会一个进化枝。

Over 90% of the world's plant species form relationships with beneficial fungi.

世界上超过 90% 植物物种与有益真菌亲缘关系。

Plateaus, forests, lakes, coastlines, These various geographical features and climate conditions have helped to form and preserve widely different species.

高原、山林、湖、海岸线，这种地理气候跨度有助于物种保存。

In large genera the species are apt to be closely but unequally allied together, forming little clusters round other species.

在大属中，物种倾向于紧密但平等地结合在一起， 在其他物种周围小簇。

Sheela Turbek: Normally, for speciation to occur organisms have to be confined to different geographic regions in order to accumulate genetic differences.

Sheela Turbek：通常情况下，要发生物种，生物体必须局限于地理区域，以便积累遗传差异。

But from reasons already assigned I can by no means agree with this naturalist, that migration and isolation are necessary elements for the formation of new species.

但是根据已经给出理由， 我决能意这位博物学家观点， 即迁徙隔离是新物种必要因素。

I was quite surprised by my results because they were contrasting to so many other species, where the oldest males sire the most offspring or the males with the largest territories.

我对研究结果感到非常惊讶，因为这些海豚与许多其他物种对比，年纪最大雄性海豚或是拥有最大领地雄性海豚繁殖最多后代。

All that we want to show is, that where many species of a genus have been formed, on an average many are still forming; and this certainly holds good.

我们想要表明是， 在一个属许多物种已经地方，平均而言，许多物种仍在； 这当然很好。

Where many species of a genus have been formed through variation, circumstances have been favourable for variation; and hence we might expect that the circumstances would generally still be favourable to variation.

如果一个属许多物种是通过变异， 那么环境就是有利于变异；因此我们可以预期环境通常仍然有利于变化。

This new center of endemism is emerging a large-scale water tower that wasn't known peatlands that weren't known, source lakes that weren't known are being documented for the first time in the 21st Century.

这个全新特有物种中心正在一个为人知大型水塔，为人知泥炭地，以及在21世纪首次被记录下来为人知源头湖泊。

And it's just about impossible to be sure  exactly which species made a particular set of tracks unless they literally died in them, so fossilized tracks aren't given the  same name as the animal that made them.

而且几乎可能确定究竟是哪些物种一组特定足迹， 除非它们真死在这些足迹中，因此化石足迹名称与制造它们动物。

This species forms a marked exception, crouching and creeping in compliance with the most rigorous demands of climate; yet enduring bravely to a more advanced age than many of its lofty relatives in the sun-lands far below it.

这个物种一个明显例外，蹲伏爬行符合最严格气候要求；然而，它比远在它下面太阳大陆上许多崇高亲戚更勇敢地坚持到更高年龄。
