The Carbon Is Moving From the Fur to the Birch

The carbon was moving from the fur to the birch. The cedar picked up a little bit, but only a small fraction of what the other two were receiving from each other. And so that told me that most of this conversation between the birch and for this passing back and forth of these carbon isotopes that most of it must be going through mycorrhizal connections. Very little was moving through the soil as was indicated by what was taken up by the cedar.
