The other type, she tells me, is arbuscular mycorrhizae.

她告诉我们，另一种是丛枝菌根。

Trees that associate with arbuscular mycorrhizae tend to have more nitrogen and phosphorus in their leaves.

与丛枝菌根关联的树木，其树叶往往含有更多的氮和磷。

Arbuscular mycorrhizae are better at acquiring phosphorus..., and ectomycorrhizae fungi are just better at acquiring nitrogen from soils.

丛枝菌根真菌跟擅长从土壤中获取磷，而外生菌根真菌则更善于获得氮。

Ectomycorrhizae and arbuscular mycorrhizae specialize in getting different nutrients, and they trade those nutrients to trees at different price points.

外生菌根和丛枝菌根分别专门获取不同养分，将这些养分以不同价位与树木交易。

And you said the arbuscular mycorrhizae, they are even smaller?

达夫：你说的是丛枝菌根，它们甚至更小？

Trees that associate with arbuscular mycorrhizae tend to have more nitrogen and phosphorus in their leaves.

达夫：与丛枝菌根相关的树木的叶子中往往含有更多的氮和磷。

Renato Braghiere: Arbuscular mycorrhizae are better at acquiring phosphorus... , and ectomycorrhizae fungi are just better at acquiring nitrogen from soils.

Renato Braghiere：丛枝菌根更擅长获取磷… … 而外生菌根真菌更擅长从土壤中获取氮。

And so what might happen is that because now we have these arbuscular mycorrhizae going into the Arctic, and they are just less efficient in acquiring nitrogen, the plants might suffer even further.

因此可能发生的情况是，由于我们使丛枝根菌进入北极，而它们吸收氮的效率较低，继而植物会雪上加霜。

So if you have a map of all the tree species in your forest, and you can very easily say, you know, 20 percent of your forest is going to be associated with arbuscular mycorrhizae...

因此如果你有森林中所有树种的地图，你就能轻松地说 20% 的森林与丛枝菌根有关。

Braghiere: And so what might happen is that because now we have these arbuscular mycorrhizae going into the Arctic, and they are just less efficient in acquiring nitrogen, the plants might suffer even further.

布拉吉埃：所以可能发生的情况是，因为现在我们有这些丛枝菌根进入北极，它们获取氮的效率较低，所以植物可能会遭受进一步的损失。
