But what has all of this got to do with our story of brazil nut trees and agoutis?

这个又跟巴西胡桃树有关系？跟刺鼠有关系？

Now, the brazil nut tree needs the agouti, way down there, to disperse the seeds.

巴西胡桃树需要地面上的刺鼠播种子。

Humans, some primates, some bats, the elephant shrew and the spiny mouse menstruate.

人类、一灵长类动物、一、象鼩和刺鼠都有月经。

The agouti needs the female orchid bee up here to pollinate the flowers so those seeds are produced in the first place.

刺鼠需要雌性兰花蜂为花朵授粉，保证能够产生种子。

The agouti is the only animal that can disperse the seeds of the brazil nut tree, so the brazil nut tree is completely reliant on the agouti.

拉美刺鼠是唯一能够帮助巴西胡桃播种子的动物，因此巴西胡桃完全依赖这种动物。

And you know, I can guarantee that every brazil nut that you've ever cracked open has come from a tree that was planted by one of these animals.

嗯，我敢打赌，你吃的每一颗巴西胡桃，都是从刺鼠埋下的种子长成的大树上结出的。
