“…The obtained differences in the rate of mass loss of Sph. fuscum and E. vaginatum are significant and are consistent with previously obtained data [12,19]. Sphagnum mosses contain the least amount of bitumen and many easily hydrolyzable and water-soluble compounds of the carbohydrate complex; therefore, sphagnum mosses should be the least resistant to decomposition.…”

“…This causes a constant increase in peat deposits and the development of bog ecosystems. There are relatively few works devoted to the study of the dynamics of decomposition of peatforming plants in bog ecosystems [6][7][8][9][10][11][12][13][14][15][16]. The rate of decomposition of plant residues depends on the chemical composition of plants and the hydrothermal conditions under which these processes occur [6,[17][18][19].…”

“…Studies conducted in bog ecosystems are mainly related to the study of the isotope composition of peat organic matter [46][47][48][49][50][51]. Very rarely have the plants themselves or the early stages of transformation of plant remains been studied [52][53][54][55][56][57]. On the territory of the southern taiga subzone of Western Siberia, the issue of changes in the isotope composition during the transformation of plant remains has practically not been studied at all [58], especially in bog ecosystems subject to anthropogenic or pyrogenic influence.…”

In this study, we describe the variation in δ13C value in the litter of two species of peat-forming plants: Sphagnum fuscum and Eriophorum vaginatum, during 3 years of field decomposition in oligotrophic bog ecosystems drained for the purpose of forest melioration and fire affected and at the stage of post-pyrogenic restoration. Litterbags were periodically retrieved in the autumn and the δ13C value in the residual litter was related to mass loss, litter chemistry, and hydrothermal conditions. Sph. fuscum decomposes much more slowly than E. vaginatum. Low rate of transformation for Sph. fuscum is observed in drained and post-pyrogenic sites, while for E. vaginatum minimal rate of transformation is observed in the native site. During the decomposition of Sphagnum residues, 13C enrichment occurs, and during the decomposition of E. vaginatum, we observed 12C enrichment. The changes in the isotope composition of carbon for investigation sites are insignificant for Sphagnum fuscum, but it was observed for E. vaginatum, the largest of 13C depletion is observed in the drained site (−28.3‰) and minimal in the postpyrogenic site (−27.4‰).

“…The dwarf shrubs predominate on the mounds where decompose more intensely than sphagnum mosses absolutely dominant in the fens [79]. Constant over-wetting of fens also inhibit peat decomposition [80,81]. This means that during the decomposition of plant residues on the mounds, a greater amount of carbon is lost through the carbon dioxide emissions and leaching into the bog waters.…”

Microtopography Controls of Carbon and Related Elements Distribution in the West Siberian Frozen Bogs

The West Siberian Plain stands out among other boreal plains by phenomenal bogging, which has both global and regional significance. The polygonal bogs, frozen raised-mound bogs, and ombrotrophic ridge-hollow raised bogs are the most extensive bog types in the study area. These bogs commonly show highly diverse surface patterns consisting of mounds, polygons, ridges, hollows, and fens that correspond to the microtopes. Here we investigated how the microtopographic features of the landscape affect the thermal and hydrologic conditions of the soil as well as the nutrient availability and consequently, the dynamics of carbon and related elements. The effect of the surface heterogeneity on the temperature regimes and depths of permafrost is most significant. All of these factors together are reflected, through the feedback system, by a number of hydrochemical parameters of bog waters, such as dissolved organic and inorganic carbon (DOC, DIC), specific conductivity (Cond), SO42–, Cl–, P, Sr, Al, Ti, Cu, V, B, Cs, Cd, Rb, As, U, and rare earth elements (REEs). Among the studied parameters, DOC, SO42, Al, V, and Mn differ most significantly between the convex and concave microforms. The DOC content in bog water is significantly affected by the water residence time, which is significantly longer in soils of mound/polygons than fens. Plants biomass is higher on the mounds which also have some effect that, due to leaching, should lead to more carbon entering into the water of the mounds. It is also shown that atmospheric-dust particles have a noticeable effect on the hydrochemical parameters of bog waters, especially on mounds. The ongoing climate warming will lead to an increase in the fens area and to a decrease in the content of DOC and many elements in bog waters.
