The share of functional groups of fungi incorporating recently photosynthesized carbon by vegetation on soil cores of three land abandonment categories. The total amount of carbon from plants to fungi is calculated as an average of three soils for each of the three time categories using the excess ¹³C labeling information of the PLFA marker 18:2ω6c and set to 1 for the long-term soils. For assignment of ITS sequences to functional groups, see text.
