Аннотация: Stable Ca and radiogenic Sr isotope compositions were measured in different compartments (stream water, soil solutions, rocks, soils and soil leachates and vegetation) of a small permafrost-dominated watershed in the Central Siberian Plateau. The Sr and Ca in the area are supplied by basalt weathering and atmospheric depositions, which significantly impact the Sr isotopic compositions. Only vegetation significantly fractionates the calcium isotopes within the watershed. These fractionations occur during Ca uptake by roots and along the transpiration stream within the larch trees and are hypothesised to be the result of chromatographic processes and Ca oxalate crystallisations during Ca circulation or storage within plant organs. Biomass degradation significantly influences the Ca isotopic compositions of soil solutions and soil leachates via the release of light Ca, and organic and organo-mineral colloids are thought to affect the Ca isotopic compositions of soil solutions by preferential scavenging of Ca-40. The imprint of organic matter degradation on the delta Ca-44/40 of soil solutions is much more significant for the warmer south-facing slope of the watershed than for the shallow and cold soil active layer of the north-facing slope. As a result, the available stock of biomass and the decomposition rates appear to be critical parameters that regulate the impact of vegetation on the soil-water system in permafrost areas. Finally, the obtained delta Ca-44/40 patterns contrast with those described for permafrost-free environments with a much lower delta Ca-44/40 fractionation factor between soils and plants, suggesting specific features of organic matter decomposition in permafrost environments. The biologically induced Ca isotopic fractionation observed at the soil profile scale is not pronounced at the scale of the streams and large rivers in which the delta Ca-44/40 signature may be controlled by the heterogeneity of lithological sources.

Аннотация: To evaluate the effects of forest fire and post-fire stand recovery on the organic layer chemistry and solute release within mound and trough microrelief elements (termed earth hummock microtopography) that mainly distribute permafrost affected area, we chose five fire plots (larch forests burned in 1951, 1981, 1990, 1994 and 2005) paired with adjacent control plots in mature larch forests in Central Siberian permafrost terrain. We determined total carbon, nitrogen and ash content in solid organic soils, and analyzed total carbon, nitrogen, bases and major anions in water extracts. There was a significant correlation between water-extracted organic carbon (WEOC) and total carbon (kg m(-2)) in area basis, implying that the quantity of total carbon was a major factor in WEOC production. WEOC correlated negatively with pH, indicating strong control by organic horizons (organic solute leaching) on soil acidity and base cation dynamics. The sum of water extractable base cations was also correlated significantly to total carbon, indicating that cations can be released through organic matter decomposition. Organic horizons in troughs in burned plots released greater amounts of Ca, Mg and K than those in mounds, probably due to greater content of organic matter as a cation source. Anions including nitrate and phosphate and WEOC also accumulated in trough depressions, due probably to organic matter degradation. The contrasting distribution of solutes between mounds and troughs in burned plots seems to be controlled by organic horizon development via changes in microtopography after forest fires.

Аннотация: Terrestrial ecosystems in northern high latitudes exchange large amounts of methane (CH4) with the atmosphere. Climate warming could have a great impact on CH4 exchange, in particular in regions where degradation of permafrost is induced. In order to improve the understanding of the present and future methane dynamics in permafrost regions, we studied CH4 fluxes of typical landscape structures in a small catchment in the forest tundra ecotone in northern Siberia. Gas fluxes were measured using a closed-chamber technique from August to November 2003 and from August 2006 to July 2007 on tree-covered mineral soils with and without permafrost, on a frozen bog plateau, and on a thermokarst pond. For areal integration of the CH4 fluxes, we combined field observations and classification of functional landscape structures based on a high-resolution Quickbird satellite image. All mineral soils were net sinks of atmospheric CH4. The magnitude of annual CH4 uptake was higher for soils without permafrost (1.19 kg CH4 ha(-1) yr(-1)) than for soils with permafrost (0.37 kg CH4 ha(-1) yr(-1)). In well-drained soils, significant CH4 uptake occurred even after the onset of ground frost. Bog plateaux, which stored large amounts of frozen organic carbon, were also a net sink of atmospheric CH4 (0.38 kg CH4 ha(-1) yr(-1)). Thermokarst ponds, which developed from permafrost collapse in bog plateaux, were hot spots of CH4 emission (approximately 200 kg CH4 ha(-1) yr(-1)). Despite the low area coverage of thermokarst ponds (only 2.1% of the total catchment area), emissions from these sites resulted in a mean catchment CH4 emission of 3.8 kg CH4 ha(-1) yr(-1). Export of dissolved CH4 with stream water was insignificant. The results suggest that mineral soils and bog plateaux in this region will respond differently to increasing temperatures and associated permafrost degradation. Net uptake of atmospheric CH4 in mineral soils is expected to gradually increase with increasing active layer depth and soil drainage. Changes in bog plateaux will probably be much more rapid and drastic. Permafrost collapse in frozen bog plateaux would result in high CH4 emissions that act as positive feedback to climate warming.

Аннотация: Terrestrial and aquatic dissolved organic matter (DOM) was characterized to trace the likely processes of DOM formation and stream export in a permafrost-dominated watershed in central Siberia. Stream samples were collected in spring (May-June 2003) and summer (July-August 2003) at both low flow and stormflow. Dissolved organic matter was analyzed by pyrolysis/gas chromatography/mass spectrometry, and identified pyrolysis products were simultaneously analyzed for compound-specific isotope ratios by isotope ratio mass spectrometry. Pyrograms of terrestrial and stream DOM contained a similar series of pyrolysis products, suggesting a terrestrial origin for DOM in the small stream draining our study catchment. However, despite the overall similarity of chemical composition of stream DOM at different seasons, we also observed distinct differences in isotopic fingerprint between seasons and hydrologic phases ( stormflow versus low flow). This variation appears to be due to the changing origin of stream DOM from different soil layers and the catchment sources following permafrost thawing during the frost-free period. In general, chemical and isotopic composition of stream DOM was similar to DOM produced in soils of colder north facing slopes ( P 0.01) with a shallow active layer. South facing slopes with deeper active layers produce little DOM that enters the stream, suggesting that DOM produced in the active layer is retained and stabilized in underlying, unfrozen mineral soils. Climate change that results in additional seasonal thawing of permafrost-dominated landscapes will decrease the amount of DOM exported to riverine systems and change its chemical composition.

Аннотация: The nitrogen pool in Russian peatlands reaches 4.69 x 10(9) t. Half of this amount is stored in humic substances (mainly, in humic acids) of peat. The nitrogen of relatively stable compounds (mainly, the humin nitrogen) constitutes about 1.8 x 10(9) t. Easily hydrolyzable and mineral nitrogen compounds constitute 9.7 and 1.8% of the total nitrogen pool, respectively. Most of the nitrogen in eutrophic bogs is bound with humic substances, while that of oligotrophic peat is represented by poorly hydrolyzable and nonhydrolyzable forms. The pool of water-soluble nitrogen constitutes 20.3 x 10(6) t, or 0.43% of the total nitrogen reserve. In the case of global warming, eutrophic and mesotrophic bogs can become an important source of ammonia emission to the atmosphere.

Аннотация: The structure and functions of the microbial complexes in the soils after surface fires of different intensity were studied. The fires of high and medium intensity were found to lead to a significant decrease in the number and functional activity of microorganisms participating in the nitrogen-carbon cycle. The degree of changes in the postfire status of the soil microbocenoses was revealed to be related to the joint action of pyrogenesis and the hydrothermal conditions at the moment of the fire rather than to the fire intensity. The favorable combination of the elevated soil moisture and soil heating stimulates the microbiological processes of organic matter mineralization, thus, improving the forest-growing conditions for the pine forests. The microbial biomass, basal respiration, and the microbial metabolic coefficient are shown to adequately reflect the postfire status of the microbial complexes.

Аннотация: Productivity of the moss cover and necromass accumulation in the litter of a sphagnum larch forest have been estimated on the basis of tree age. It has been shown that the total carbon stock in the litter of a 100-year-old stand, including organic matter not destroyed by fire, exceeds the corresponding value for the tree stand itself by more than,an order of magnitude. The accumulation of organic matter on the soil surface inhibits the growth of larch. In particular, this factor impairs hydrothermal conditions in the soil and causes a rise of the permafrost table; as a consequence, lower layers of the root system die off.

Аннотация: The dynamics have been studied of the ecological-functional parameters (EFP) of replantozems formed on the dumps of the Borodinskiy open-pit coal mine in the Kansk-Achinsk Coal Basin (55A degrees 52' N, 94A degrees 54' E) that were not involved into agricultural use during the first 30 years. The work was based on the integrated analysis of the agrochemical properties and the EFP, which characterized the state of the plant cover, the microbial cenoses, and the biochemical activity of the replantozems representing a chronological series (5, 20, and 30 years). Multicomponent plant communities were formed on the surface of the replantozems over the 30-year period. The filled horizon of the replantozems was slowly involved into the metabolic processes. The thickness of the biologically active layer did not exceed 10 cm. The microbial cenosis's functional activity was relatively stabilized, and the values of the microbial biomass and basal respiration approached the background ones only in the upper (0-5 cm) layer. The biochemical activity of the microorganisms agreed with the changes in the properties of the upper (0-10 cm) layer of the replantozems: the contents of the total nitrogen and humus increased, as well as the degree of the humic acids "maturity" and the concentration of the mobile phosphorus, while the alkalinity decreased.

Аннотация: The results of a field experiment for studying the seasonal dynamics of the CO2 (R-all) emitted from the overburden and enclosing rocks of a coal mine are presented as an integral index of their biological activity. The mean rate of the CO2 emission from the control substrate was 1.2 g C/m(2) per 24 h. The intensity of R-all for the variant with the application of mineral and complex fertilizers, along with a microbiological preparation, was higher by 28 and 34%, respectively. In the same variants, the R-all values little changed during the whole growing period. The measurements of the potential respiration of the rock mixture in the laboratory showed that a significant part of the CO2 flux was formed at the expense of carbon dioxide of abiotic origin. The values of the CO2 emission are concluded to be overestimated as compared to those for the real level of the biological activity of the substrates studied.

Аннотация: The data of experimental studies on the postpyrogenic dynamics of the litter in mountain taiga cedar (Pinus sibirica), pine (Pinus sylvestris) and subtaiga forest-steppe pine (Pinus sylvestris) forests in the Baikal region are analyzed. Ground fires prevailing in this region transform the surface organic diagnostic horizons of soils and result in the formation of new pyrogenic organic horizons (Opir, OLpir, OL/Opir, OApir). The adverse impact of ground fires on the thickness, reserves, moisture capacity and fractional composition of forest litters is shown. The data on the chemical ash composition of litters, as well as the content of mobile microelement compounds is also given. The tendency of reducing the concentration of mobile elements in the organic horizons of soils from the taiga Siberian pine (cedar) altitudinal zonal complex (AZC) to the subtaiga forest-steppe pine AZCC of forest types was revealed. Forest fires were found to cause great quantitative and qualitative changes in the chemical composition of surface organic pyrogenic horizons; they are especially manifested in the transformation of their labile properties (?H, exchangeable cations, total and mobile nitrogen, etc.).

Аннотация: Quantitative relationships between the active acidity of peat soils on the one hand and their exchange acidity (pH(KCl)), nonexchangeble (total potential) acidity (1M CH3COONa extract), contents of exchange cations and alkaline-earth bases, and base saturation degree, on the other hand, have been identified in the form of a linear function. Coefficients of the resultant regression equations are provided. The high predictive capability of the produced regression models is proven using independent data as examples. The use of regression equations eliminates the need for time-consuming chemical analytical works, thus making it possible to operatively classify wetlands and peat soils on the basis on their chemical properties: saturation with alkaline-earth bases and pH value. The botanical composition may also be used as a reliable indicator, provided that the degree of peat decomposition is low and subject to special knowledge of morphology and anatomy of sphagnum mosses and vascular swamp plants.

Аннотация: For the first time, using the example of a key object of the peat river valleys of the Kuznetsk Alatau occupied by spruce forests, it is shown that swamp waters are clearly differentiated by the content of the main ions due to forest-peat fires. Swamp waters objectively form three groups: (1) waters of the original type of mineral nutrition (fresh, soft), (2) waters of peatland covered by a medium fire (fresh, hard), (3) waters of peatland covered by a high fire (slightly saline, very hard). Magnesium ions and bicarbonates have the highest discriminating power (95%) in the determination of swamp waters. The swamp waters of the post-pyrogenic peatland do not lose the ratio of the main ions, which is similar to waters of the original type, and retain the hydro-carbonate calcium-magnesium composition.
