Аннотация: Validating methodology for quantifying of carbon (C) loss from dead wood is critical for understandingC turnover in forest ecosystems. We compared estimates of CO2 fluxes with a closed dynamic chambermethod using an infrared gas analyzer with: 1) small chambers installed on the downed woody debris(DWD) surface and 2) DWD segments placed in large chambers. The fluxes were measured from 6 intermediatelydecayed DWD fragments, wood and bark of Betula pubescens and Populus tremula and calculated onthe surface area, volume and mass bases. For most DWD fragments, the tendency with an underestimationof CO2 flux in the first approach up to 90% was observed due to a barrier effect of a thick bark layer and possiblegas leakages. Our results demonstrate the importance of taking into account contribution of bark intototal DWD respiration rates especially in upscaling the piece-level results into ecosystem level.
