On the basis of the various rates measured for a wide variety of soils, global soil methane oxidation ranges between 5 and 60 Tg/year. These values are approximately 1 to 10% of the current estimates for net methane flux to the atmosphere [Dörr et al., 1993]. Methane uptake by soils is an appropriate process to model globally because the probable c...

The methane emission from typical bog landscapes of the West Siberian subtaiga was studied in the summer-autumn of 2007–2010. The lowest specific fluxes (the median value is 0.08 mg C-CH4/m2 per h) were recorded from ryams (raised bogs with dwarf shrub-sphagnum associations). From the ridges of the ridge-pool complexes, the fluxes were estimated at...
Thesis
The hydrology of mires (pristine peatland ecosystems) hardly has been analyzed quantitatively. The general idea, that mires can retain precipitation water (`sponge effect') has never been proved by real field data. Missing data for evaluation of these properties are actual evapotranspiration, water conductivity and interception of rainwater by peat...

Гидрология болот (ненарушенных экосистем торфяников) с трудом поддается количественному анализу. Основное предположение, используемое при количественном описании гидрологии болот, состоит в том, что болота могут сохранять воду, поступившую с сосадками («эффект губки»). Но это предположение никогда не было доказано на основе экперементальных полевых...
