Аннотация: Between 72 and 88% of carbon (C) loss in forest litter decomposition returns to the atmosphere in the form of carbon dioxide. The share of water-soluble organic products does not exceed 3-4%. Between 8% under spruce and 25% under aspen and pine of the total C loss from litter organic matter goes to the formation of humus. Decomposition intensity of the dead organic matter on the soil surface is close to annual litterfall income (except under cedar). The specific rate of decomposition processes among the coniferous litters is minimum for cedar (167 mg C g-1 yr-1) and maximum for larch (249 mg C-1 yr-1). The spicific rate of decomposition of organic residues under aspen and birch canopies are 344 and 362 mg C-1 yr-1.

Carbon pools and fluxes of 25-year old coniferous and deciduous stands in Middle Siberia
The structure and biodiversity after fire disturbance
: материалы временных коллективов / O. A. Zyryanova, V. I. Zyryanov et al // Eurasian Journal of Forest Research. - 2007. - Vol. 10-1. - С. 19-29. - Библиогр. в конце ст.
Аннотация: Larix gmelini is one of the most widespread larch species in northern Eurasia as a whole and in the Rissian Federation dominating here in both the distribution area and the growing stock. Owing to high adaptability and ecological plasticity it occupies different sites within its range and performs well under continuous permafrost conditions. Over an immense area Gmelin larch forests differ in species composition, ecosystem sytucture and the features of natural regeneration. Ground fires are the main force driving larch forest development. Depending upon site conditions, fire intensity and periodicity, fire regimes determine forest age structure, species diversity, spatial-temporal dimensions of larch ecosystems as well- as succession patterns in their trends and rates. Based on the results of long-term investigatiobs we discuss Gmelin larch forest post-fire dynamics in the central part of their distribution in Siberia versus the southeastern part in Priamurye in the Rissian Far East.

Regeneration after forest fires in mixed conifer broad-leaved forests of the Amur region in Far Eastern Russia: the relationship between species specific traits against fire and recent fire regimes
: материалы временных коллективов / M. Kobayashi, Y. P. Nemilostiv, O. A. Zyryanova et al // Eurasian Journal of Forest Research. - 2007. - Vol. 10-1. - С. 51-58. - Библиогр. в конце ст.
Аннотация: The number of forest fires has been increasing in the mixed conifer broad-leaved forests in the southern part of Far Eastern Russia. We should analyze the effect of this new fire regime on the vegetation and carbon budget in the forest ecosystem of this region. As each woody species develops specific traits to adapt to certain fire regimes, a change of fire regime affects each species differently. This can result in the alteration of the species composition of forest ecosystems. In the present study, we rewieded those adaptive traits exhibited by species in the region, and hypothesized a possible mechsnism for the changes of species composition and amount of biomass stock that would result from the new fire regime. The new fire regime described were an increased frequency of both intense canopy fires and low intensity surface fires. Both kinds of increased fire result in an increase of Betula platyphylla forests, but with different mechanisms. We proposed that an increase of Betula platyphylla forests due to either mechanism results in a decrease of biomass density.

The difference in the lignification of earlywood and latewood in larch (Larix sibirica Ldb.)
: материалы временных коллективов / G. F. Antonova, T. N. Varaksina, V. V. Stasova // Eurasian Journal of Forest Research. - 2007. - Vol. 10-2. - С. 149-161. - Библиогр. в конце ст.
Аннотация: The rate of lignin deposition, its content and composition, and molecular weight distribution of different stages of secondary wall thickening during tracheid development of both earlywood and latewood in Siberian larch (Larix sibirica Ldb.) were studied in the stems of 25-year-old trees. The cells of early and late xylem at different stages of secondary wall development were obtaint in late June and early in August, respectively. Lignification of the two types of wood was found to involve different dynamics. The intensity of lignin synthesis during earlywood formation increases gradually, reaching the maximum at the last stage of tracheid maturation. In contrast, lignin deposition in the course of latewood development is the highest only in the first stage of lignification and declines by the end of tracheid maturation. There were differences in the composition of alkaline oxidation products of lignin preparations at different development stages of early and late xylem. The amount of cell wall substances deposited before lignification in earlywood is larger than that in latewood.

Аннотация: Research to monitor and document surface fire behavior characteristics in Scots pine forests of Central Siberia. Fifteen successful burns were conducted under a range of burning conditions (2000-2003). Fuel consumption, depth of burn, rate of spread, and fire line intensity were successfully modelled using the Russian Moisture Index (PV-1) or the Canadian Forest Fire Weather Index System as the independent variables, which should prove useful in suppression efforts undertaken by Russian fire agencies.

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: An emperical fire study, using 2 to 4-ha experimental burn plots, was conducted in Central Siberia to obtain data to develop fire behaviour models for Scots pine forests. Fuel consumptiuon (depth of burn and fuel consumption) was predicted using the Russian Moisture Index (PV-1) or the Canadian Forest Fire Weather Index (FWI) System. However, only the FWI System could be used to model fire behaviour characteristics (rate of spread and fireline intensity), as wind speed is an important input factor in its calculatiion and is not accounted for in the PV-1.

Аннотация: Pyrogenic transformations of the physical state of cryogenic soils in the southern and middle taiga were investigated. The long-term dynamics of the microclimate on burns and the soil temperature and moisture to the depth of 120 cm were studied. Data on the postfire restoration of the ground cover are presented. Experiments on artificial sprinkling of burned areas differing in the degree of the burning out of the forest litter, the slope gradient, etc., have been performed. An experimental model demonstrating the relationships between the surface runoff and five environmental factors has been proposed. The pyrogenic destruction of the ground cover and the lower phytocenosis layers was accompanied by significant disturbances of the microclimate and anomalous thawing of the permafrost on the burns. In the pine stand on the colluvial fan after the intense fire, the soil temperature at the depth of 10 cm ( in the summer) exceeded the control value by 3-5 degrees C; in the larch forest on the southern slope of the Stanovoi Ridge, it increased by 1.5-2.0 times after the fire of medium intensity. On the mountain slopes, the surface runoff was significantly intensified, which resulted in drastic environmental and silvicultural consequences.

Аннотация: A change in the mass and composition of organic matter in the phytomass and soil of pine forests affected by mid-intensity and high-intensity fires is considered. It is shown that a mid-intensity fire did not catastrophically affect the pool of carbon in the middle-aged pine forests of the subtaiga forest-steppe and the taiga higher belt areas in the southwest of the Baikal region. Five years after a high-intensity fire, the carbon reserves in a mature taiga pine forest remain 20% lower than in an unaffected pine forest. Compared with the reference figures, the mass of C and soil cover in the stand phytomass decreased by 18 and 63%, respectively. In the easily mineralizable fraction of organic matter, the reserves of carbon decreased by half owing to burnout of waste wood (by 64%) and root detritus (by 50% compared with the reference tree stand figures).

Аннотация: This study focused on structural analysis of ground carbon storage following fires in light conifer stands of the Lower Angara region (Siberia, Russia). Experimental fires of varying frontal intensity were conducted at Scots pine and mixed larch forests of southern taiga. Considerable amounts of surface and ground forest fuels (21-38 tC ha(-1)) enhanced low-to high-intensity fires. Post-fire carbon storage decreased by 16-49% depending on fire intensity and rate of spread, with depth of burn being 0.9-6.6 cm. Carbon emissions varied from 4.48 to 15.89 t ha(-1) depending on fire intensity and forest type. Depth of burn and carbon emissions for four major site types were correlated with a weather-based fire hazard index.

Аннотация: Experimental data on the effect of surface fires on the organic matter transformation in the gray-humus soils of pine forests were obtained in the southwestern part of the Baikal region. The application of methods of thermal analysis (such as differential scanning calorimetry and thermogravimetry) made it possible to obtain qualitative and quantitative information about the decomposition (oxidation) of the components of the soil organic matter upon their heating. It was found that the organic matter content in the soils subjected to fires of high intensity decreased by 1.9 times in comparison with the control. In the litter horizons of the undisturbed soils, thermolabile components (mostly, oligo- and polysaccharides) comprised 61% of the organic matter, and the portion of thermostable components (aromatic compounds) was 39%. A significant decrease in the content of thermolabile components and an increase in the content of thermostable components (up to 62%) were observed in the organic matter of the postpyrogenic forest litter as a result of the charcoal formation during the fire.

Аннотация: Consideration is given to the results of studies on the postfire dynamics of Transbaikal forests, which are formed under conditions of highly arid climate and extreme pyrological regime. Data are presented on tree die-off and recruitment in naturally burned forests and in test stands affected by creeping fires differing in intensity. The hydrothermal regime of soils, precipitation runoff, and its multifactor models are discussed. It is shown that fires aggravate moisture deficiency on mountain slopes, impair the productivity of tree stands, and cause their digression. The statistics of forest fires and the risk of lightning fires are analyzed.

Аннотация: The postfire transformation of the functional activity of the microbial cenoses and the main soil properties under mixed larch forests were studied in the lower reaches of the Angara River. It was shown that the intensity of the postfire changes in the population density, biomass, and activity of the microorganisms in the dark podzolized brown forest soil depended on the degree of burning of the ground cover and the surface litter during the fire. The maximum effects of the fire on the microbial cenoses were observed in the litter and the upper 5-cm-thick layer of the dark-humus horizon in the areas of intense burning. The postfire restoration of the structural-functional activity of the microbial cenoses was determined by the degree of transformation of soil properties and by the postpyrogenic succession in the ground cover. The microbial complexes of the dark podzolized brown forest soils under mixed larch forests in the studied region restored their functional activity after the fires of different intensities quicker than the microbial cenoses of the sandy podzols in the pyrogenic lichen-green-moss pine forests of the same zone.
