Kern and her team observed seven different groups of wild dwarf mongooses in South Africa.

科恩和团队在南非观察了七组不同野生群。

Everyone in the mongoose pack helps look after their pups.

群里每个人都帮助照顾它们幼崽。

So any mongooses hunting for bugs can keep calm and carry on.

这样一来，找虫子侏獴就可以保持冷静，继续找虫子。

Not to say mongoose society is quite as complex as ours.

这并不是说侏獴社会像我们人类社会那样复杂。

And now we have evidence for an unusual mutual relationship—between warthogs and banded mongooses.

现在有证据表明疣猪和条纹之间存在不同寻常相互关系。

Small, tasty mammals like dwarf mongooses have one main goal: do not get eaten.

不要被吃掉。

They need time to recover before becoming fully contributing members of mongoose society.

它们需要时间恢复，然后才能成为族群中有充分贡献成员。

That could do something like increase rat and mongoose populations, which are known to be nest predators of native birds.

这可能会增加老鼠和，众所周知，这两种动物是本土鸟类巢穴掠食者。”

For example, Pallas's cats and mongooses are both small ambush predators, but the Pallas's cat has round pupils and mongooses have goat-like pupils.

例如，帕拉斯和都是小型伏击捕食者，但帕拉斯有圆形瞳孔，有山羊般瞳孔。

The study included ring-tailed lemurs, which come from large social groups, as well as lemurs from small-groups, like the mongoose lemur.

研究包括节尾狐猴，来自大社群，还有从小社群来狐猴，比如獴狐猴。

When new immigrants shows up, that means more mongooses can act as lookout against predators. Right? In reality, it's more complicated.

当新加入出现时，就意味着有更多可以充当警戒捕食者监视员，对吧？而事实要复杂得多。

But at a very basic level - it appears mongoose society also follows the rule, You scratch my back, and I'll scratch yours.

但从非常基础层面来说，似乎侏獴社会也遵循“投桃报李”这一规则。

It wasn't until they'd been in their new groups for five months, on average, that they spent as much time working as lookout as the other mongooses did.

平均来说，它们在加入新群体五个月以后，才能和其他一样担任哨兵工作。

In a playback study, the researchers found that mongooses responded far less to the sentinel calls of recent immigrants than to those from others they already knew and trusted.

在回放研究中，研究人员发现，与其它已经了解且信任成员相比，对新人哨兵呼叫反应要少得多。
