For one, we found that natural regeneration under these trees has increased manifold when we have old trees.

首先，我们发现，当我们有了老树时，这些树下的自然再生能力会成倍增加。

Ramos' work, and that of other researchers after him, helped show that the bird was a disperser of the spores of several native fern species and, hence, plays an important role in the natural regeneration of the forest.

拉莫斯以及他之后的其他研究人员的工作帮助表明，这种鸟是几种本地蕨类植物孢子的传播者，因此在森林的自然更新中发挥着重要作用。
