| Description | The concentration of dissolved organic carbon (DOC) and the contents of water-extractable organic carbon (WOC) and minerals were measured in moss and soils before and after a prescribed fire in interior Alaska to clarify the effect of the fire on the DOC dynamics in soil with discontinuous permafrost. The DOe concentration in the soil solution retrieved from suction cup lysimeters in the moss layer decreased from 30 (α 8.7 SD) mg C $L^{−1}$ before the fire to 11–14 (α 7.2–8.9 SD) mg C $L^{−1}$ 1 month after the fire. The woe content in the moss layer (including black carbon) 1 year after the fire was significantly lower in the burned plots (0.2–0.7 mg C $g^{−1}$) compared to the controls (2.8–4.7 mg C $g^{−1}$). The water extractable inorganic mineral contents in the moss layer were also lower in the burned plots, especially for iron, aluminum, potassium, and sodium. Our results indicated that the fire significantly decreased the DOe concentration in the surface moss layer compared to that in the unburned site about 1 month after the fire and also decreased the contents of woe and water-extractable inorganic cations in the moss layer compared to the unburned site even 1 year after the fire. |
