What's the Connection Between the Fungi and the Trees?

David Reed grew pine seedlings in a common garden and inoculated them with a fungus. He then took some radioactive carbon and he added it to the atmosphere of one of the seedlings. It actually traced the C14 into the other plant directly through this network of fungi that were linking the two plants together. In the UK, there was a bunch of researchers that were really suspicious of this, that it didn't fit the model of how these communities were constructing themselves.
