But Gore studies the same sort of mutualism in microbes.

但格尔研究了微生物中的这种互惠共生关系。

This type of mutually beneficial relationship is called, appropriately, mutualism.

这种互惠互利的关系被恰当地称为互惠主义。

Another classic example of mutualism is between plants and pollinators, like butterflies, birds, and bats.

另一个互惠共生的经典例子是植物和传粉者之间的关系，比如蝴蝶、鸟类和蝙蝠。

Mutualism is obviously common in nature, but it's uncommon to find it between two different mammal species.

互利共生在自然界很常见，但是两种不同哺乳动物之间的共利共生现象却很罕见。

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形成了互惠共生关系。”
