Each level of the forest forms its own little world, home to different kinds of living things.

在人类己知的390，000种植物物种，在亚马孙可以找到40，000多种。这棵高大、古老的巴西坚果树 结出的坚果我们可以食用；这些睡莲（叶片）大到可以躺在上面。雨林的不同层次养活的野生动物种类多 到难以置信。最底层是下的根系。往上是阴暗森林表厚实的落叶层。再往上一层由低矮的叶植物组 成。然后是高耸、古老的叶树，最后是那些离之高的大树的树冠。雨林的每一层都自成一个小世 界，成为各种生物的家园。

Deciduous trees like birch and aspen live for about 100 years, so the team couldn't simply wait for one or two centuries to find out what happens in the forest.

The added carbon accumulation, as the forest regime regenerates and shifts from coniferous to deciduous trees-that's like putting the parking brake on while driving the bus, says Johnstone.

约翰斯通表示，随着森林环境更新，针叶树转变到叶树，增加的碳积累就像在驾驶公共汽车时踩刹车一样。

Fortunately they prefer the succulent broad-leaved triticum and other woodland grasses to the silky species of the meadows, and therefore seldom bite them or set foot on them.

幸运的是，它们更喜欢多汁的叶小麦和其他林草类， 而不是草上的丝质植物， 因此很少咬它们或踏上它们。
