TeaComposition experiment results in Mukhrino field station

Basic Information
Short-term standard litter decomposition across three different ecosystems in middle taiga zone of West Siberia. The method of standard litter (tea) decomposition was implemented to compare decomposition rate constants (k) between different peatland ecosystems and coniferous forests in the middle taiga zone of West Siberia (near Khanty-Mansiysk). The standard protocol of TeaComposition initiative was used to make the data usable for comparisons among different sites and zonobiomes worldwide. This article sums up the results of short-term decomposition (3 months) on the local scale. The values of decomposition rate constants differed significantly between three ecosystem types: it was higher in forest compared to bogs, and treed bogs had lower decomposition constant compared to Sphagnum lawns. We speculate that dry weather conditions could make large influence on decomposition dynamics in short-term scale and the experiment should be repeated in ongoing years thereby. In general, the decomposition rate constants were close to reported earlier for similar climatic conditions and habitats.
