Аннотация: It is marked, that during four year period of research soil respiration rate was essentially dependent on both microrelief elements (0.4-5.umol CO2/m2/s) and meteorological conditions of a year (1.0-3.77 umol CO2/m2/s). For the control plot, irrespectively for microrelief, the presence of powerfully developed litter and great number of roots have had the main direct effect on CO2-emission.

Аннотация: High CO2 emission value in Berry site during vegetative period may explained by the large proportion of dwarf shrub biomass (6.48 t/ha) and its high respiration rate. In contrast, in Moss site stable higher respiration rate may be conditioned by thermoresistance of ground cover components.

Аннотация: Siberian boreal forest fires burn large areas annually, resulting in smoke that release large amounts of particulate emission into the atmospere. We sampled aerosol emissions from experimental fires of three Scots pine (Pinus sylvestris L.) forest sites of central Siberia. Emissions from ground-based aerosol samples were 0.1-0.7 t/ha. This value represented 1%- 7% of the total biomass (10-30 t/ha) consumed during the experimental fires. We were able classify the chemical composition of 77%-90% of the mass of particulate the emissions. Chemical analysis indicated that an average of 8%-17% of the particulate composition was of mineral emission.

Аннотация: CO2 emissions from various vegetation components were studied in larch-dominated stands (Larix gmelinii (Rupr.) Rupr.) in the Central Evenkia region of Siberia, Russia, during growing season in 2001. We found a clear relationship between air temperature and CO2 emission rate of the dominant vegetation components (such as Sphagnum and green mosses, lichens, and dwarf shrubs). The CO2 emission rate of Sphagnum, green mosses, and lichens (measured as CO2 evolution from their surface) ranged from 0.04 to 0.24 mg CO2 g(-1) oven-dry weight (odw) h(-1) during growing season. The CO2 emission rate of the aboveground parts of dwarf shrubs ranged from 0.65 to 5.54 mg CO2 g(-1) odw h(-1). The contribution of the different components of the vegetation cover varied among stand types.

Аннотация: The CO2 flux was positively correlated with soil temperature and negatively correlated with soil moisture. The CO2 flux was lowest in the Aulacomnium patch among the patches because of the low soil temperature and high soil moisture. The CO2 emission and CH4 uptake were smaller the previously reported values. The C/N ratio in soil might be an important factor explaining the low CO2 emission, and the low CH4 production may be related to the microtopography at the site.

Аннотация: The total environmental damage induced by pollution by smoke from wildfires is difficult to evaluate even roughly. This is partly due to insufficient data on smoke pollution, which is in turn attributed to unsufficient or even lacking estimated data composition and amounts of emissions from wildfires. Laboratory analysis of smoke producing capability (SPC), or smoke production coefficient would enable to make compilation of a comprehensive database of negative impacts smoke emission of wildfire. Our study showed that for boreal Siberian species the greatest SPC produced birch bark (Betula).

Аннотация: The increasing of burning area in Siberia, the extension of fire season and fires intensity lead to significant carbon emission. One of the important tasks is to describe the spread of smoke aerosol and other combustion products using actual meteorological data and fire state information. A smoke aerosol covers territory hundreds times larger than the burning area and has an effect on forming the cloud and sediment formation exactly above the fire zone.

Аннотация: Boreal forests constitute the world's largest terrestrial carbon pools. The main natural disturbance in these forests is wildfire, which modifies the carbon budget and atmosphere, directly and indirectly. Wildfire emissions in Russia contribute substantially to the global carbon cycle and have potentially important feedbacks to changing climate. Published estimates of carbon emissions from fires in Russian boreal forests vary greatly depending on the methods and data sets used. We examined various fire and vegetation products used to estimate wildfire emissions for Siberia. Large (up to fivefold) differences in annual and monthly area burned estimates for Siberia were found among four satellite-based fire data sets. Official Russian data were typically less than 10% of satellite estimates. Differences in the estimated proportion of annual burned area within each ecosystem were as much as 40% among five land-cover products. As a result, fuel consumption estimates would be expected to vary widely (3%-98%) depending on the specific vegetation mapping product used and as a function of weather conditions. Verification and validation of burned area and land-cover data sets along with the development of fuel maps and combustion models are essential for accurate Siberian wildfire emission estimates, which are central to balancing the carbon budget and assessing feedbacks to climate change.

Аннотация: We determine the net land to atmosphere flux of carbon in Russia, including Ukraine, Belarus and Kazakhstan, using inventory-based, eddy covariance, and inversion methods. Our high boundary estimate is -342 TgC yr(-1) from the eddy covariance method, and this is close to the upper bounds of the inventory-based Land Ecosystem Assessment and inverse models estimates. A lower boundary estimate is provided at -1350 TgC yr(-1) from the inversion models. The average of the three methods is -613.5 TgC yr(-1). The methane emission is estimated separately at 41.4 Tg C yr(-1). These three methods agree well within their respective error bounds. There is thus good consistency between bottom-up and top-down methods. The forests of Russia primarily cause the net atmosphere to land flux (-692 TgC yr(-1) from the LEA. It remains however remarkable that the three methods provide such close estimates (-615, -662, -554 TgC yr(-1)) for net biome production (NBP), given the inherent uncertainties in all of the approaches. The lack of recent forest inventories, the few eddy covariance sites and associated uncertainty with upscaling and undersampling of concentrations for the inversions are among the prime causes of the uncertainty. The dynamic global vegetation models (DGVMs) suggest a much lower uptake at -91 TgC yr(-1), and we argue that this is caused by a high estimate of heterotrophic respiration compared to other methods.

Аннотация: Changes in the composition of microbial complexes and their biochemical activity in soil in the vicinity of a strong source of HF emission have been studied. A sharp decrease of the biomass, the number of asporous bacteria and actinomycetes, and a smaller decrease of the number of microscopic fungi has been revealed, along with a decrease in the enzymatic and respiratory activity of contaminated soil with the relative increase in the fraction of sporiferous bacteria. On the basis of the response of introduced population of Bacillus subtilis to different doses of HF, NaF, Na(2)SO(3) microbiological norm-fixing for technogenic soil ecosystems has been carried out.

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: Measurements of midday vertical atmospheric CO(2) distributions reveal annual-mean vertical CO(2) gradients that are inconsistent with atmospheric models that estimate a large transfer of terrestrial carbon from tropical to northern latitudes. The three models that most closely reproduce the observed annual-mean vertical CO(2) gradients estimate weaker northern uptake of -1.5 petagrams of carbon per year (Pg C year(-1)) and weaker tropical emission of +0.1 Pg C year(-1) compared with previous consensus estimates of -2.4 and +1.8 Pg C year(-1), respectively. This suggests that northern terrestrial uptake of industrial CO(2) emissions plays a smaller role than previously thought and that, after subtracting land-use emissions, tropical ecosystems may currently be strong sinks for CO(2).

Аннотация: Data on the postfire dynamics of soil properties in the foci of Siberian moth population outbreaks are considered. It has been shown that controlled fires set in pest-defoliated forests result in the loss of approximately 75% of carbon and 50% of nitrogen from the forest litter through their emission into the atmosphere and in the enrichment of the upper soil horizons with potassium and phosphorus (this concerns both total and movable forms). Microbiological processes in the organogenic horizon undergo significant transformation, the density of microarthropods decreases, and the abundance of mites becomes hundreds of times lower.

Аннотация: To estimate the probable contribution of northern forest soils to the global budget of greenhouse microgases. the cryogenic soils along the Yenisei meridian have been studied with respect to their potential denitrification and carbon mineralization activities. It is shown that the forest soils of the boreal zone have a high denitrification potential and, under conditions of a high nitrate nitrogen content, may be a source of nitrous c oxide emission. A significant correlation is observed between N2O and CO2 emissions (r = 0.85, p 0.001).

Аннотация: In the southern-taiga low grass-green moss fir forest completely defoliated by the Siberian moth, the rate of soil respiration in the third year after the pest population outbreak was 1.5 times higher than in an undisturbed tree stand. This was explained by a significant increase in the abundance and activity of soil microorganisms in the pest-defoliated forest, which occurred due to the qualitative changes in the litter composition and the increased temperature and moisture in the upper soil layers. The rate of carbon emission from the soil in the defoliated forest was 41.7 kg/ha per day, compared to 28.3 kg/ha per day in the undisturbed fir forest.

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 effect of six Siberian tree species on two stages of denitrification-N2O production and consumption-was studied. Broadleaf species (aspen and birch) proved to have lower rates of N2O consumption compared to coniferous species. The factors influencing production and consumption of N2O were also evaluated. The replacement of coniferous forests with broadleaf trees will double the N2O/N-2 ratio in the denitrification end-products. Doubled N2O emission from Siberian forest soils to the atmosphere can be expected due to changes in tree species composition of forest ecosystems even without considering changes in water and temperature regimes in soil.
