The aim of this study was experimental assessing the emission of greenhouse gasses (CO2, CH4) from decomposed coarse woody debris in northern boreal forests of Siberia, where the main forest-forming species is larch (Larix gmelinii (Rupr.) Rupr.). Logs samples were collected in northern boreal larch forests of Central Evenkia (64пїЅN, 100пїЅE) at different stages of decomposition and placed in gas-tight boxes. Gas samples were measured in dynamics: at the beginning of the experiment and after 3 hour, 24 hours, aft...

We aimed at identifying the microbial response and associated release of CO2 and CH4 in/from thawing soil that has been permanently frozen. For that we performed an in situ field-based incubation experiment in a rim of ice-wedge polygon on Samoylov island, Lena Delta, Russia (72пїЅ22пїЅN, 126пїЅ28пїЅE). Frozen "buried' organic matter were taken from eroded Lena river bank and transferred to the soil surface in a rim of ice-wedge polygon. The principle includes that formerly frozen soil is moved to the active layer...
