Aggregate size class distributions (a) and transformation pathways, percentage of the original size class that is transformed into the new size class (b) (mean ± SE, N = 3) in soils incubated with or without AMF for five weeks. L Ma—large macroaggregates (1–2 mm), S Ma—small macroaggregates (212–1000 μm), Mi—microaggregates (53–212 μm), P—primary particles (<53 μm). a Initial—Size class distribution before treatments were applied. b Solid lines indicate significant differences between soils with and without AMF, while dashed lines indicated nonsignificant differences. Line thickness represents magnitude of the transformation pathway
