Аннотация: Direct measurements of CO2 and water vapour of regenerating forests after fire events (secondary succession stages) are needed to determine the role of such disturbances in the biome carbon and water cycles functioning. An estimation of the extension of burnt areas is also required in order to quantify NBP (net biome productivity), a variable that includes large-scale carbon losses (such as fire) bypassing heterotrophic respiration. Hence, eddy covariance measurements Of CO2 and water vapour were carried out in a natural regenerating forest after a fire event. Measurements were collected continuously over a Betula spp. stand in central Siberia during summer 1999. Minimum carbon exchange rate (NEE, net ecosystem exchange) exceeded -30 mumol m(-2) s(-1) (net flux negative indicating CO2 uptake by vegetation) and the partitioning of the available energy was mostly dominated by latent heat flux. Structure, age and composition of the forest were analysed to understand the secondary succession stages. The results were compared with previous studies on coniferous forests where biospheric exchanges of energy were dominated by sensible heat fluxes and small carbon uptake rates, thus indicating rather limiting growing conditions. A classification of a Landsat-4 Thematic Mapper scene has been carried out to determine the magnitude of burnt areas and the extension of broadleaf regenerating forests. Analysis of burnt areas spatial frequency and carbon exchanges of the regenerating forest stress the importance of considering large area disturbances for full carbon accounting.

Plant species composition dynamics on the initial stages of postfire progressive successions in Siberian cryolithic zone
: материалы временных коллективов / O. A. Zyryanova, T. N. Bugayenko, N. N. Bugayenko, Y. Matsuura // Proceedings of the seventh symposium on the joint Siberian permafrost studies between Japan and Russia in 1998 : Hokkaido University, 1999. - С. 59-66. - Библиогр. в конце ст.
Аннотация: In 3-4 years after the fire the number of the vascular plants is 1:2-1.3 times more as compared to that of radial larch association. Both the appearance of the new plant species and their families as well as the restitution on beforefire plants are responsible for the high level of species diversity on the initial stages of progressive successions. Temporal and spatial structure of the radical larch community is destroyed in two years after the fire.

A trace-gas climatology above Zotino, central Siberia
/ J. Lloyd, N. Tchebakova, O. Shibistova // Tellus. Series B: Chemical and physical meteorology. - 2002. - Vol. 54B, № 5. - С. 749-767
Аннотация: Using light aircraft and at intervals of approximately 14 days, vertical profiles of temperature, humidity, CO2 concentration and C-13/C-12 and O-18/O-16 ratio, as well as concentrations of CH4, CO, H-2 and N2O, from about 80 to 3000 m above ground level have been determined for the atmosphere above a flux measurement tower located near the village of Zotino in central Siberia (60degrees45'N, 89degrees23'E). As well as being determined from flask measurements (typically at heights of 100, 500, 1000, 1500, 2000, 2500 and 3000 m) continuous CO2 concentration profiles at 1 Hz have also been obtained using an infrared gas analyser. This measurement program is ongoing and has been in existence since July 1998. Data to November 2000 are presented and show a seasonal cycle for CO2 concentration of about 25 mumol mol(-1) within the atmospheric boundary layer (ABL) and about 15 mumol mol(-1) in the free troposphere. Marked seasonal cycles in the isotopic compositions Of CO2 are also observed, with that of oxygen-18 in CO2 being unusual: always being depleted in the ABL with respect to the free troposphere above. This is irrespective of whether the CO2 concentration is higher or lower in the free troposphere. We interpret this as indicating a net negative discrimination being associated with the net terrestrial carbon exchange, irrespective of whether photosynthesis or respiration dominates the net carbon flux in this region. During winter flights, large fluctuations in CO2 concentration with height are often observed both within and above the stable ABL. Usually (but not always) these variations in CO2 concentrations are associated with more or less stoichiometrically constant variations in CO and CH4 concentrations. We interpret this as reflecting the frequent transport of polluted air from Europe with very little vertical mixing having occurred, despite the large horizontal distances traversed. This notion is supported by back-trajectory analyses. Vertical profiles Of CO2 concentration with supplementary flask measurements allow more information on the structure and composition of an air mass to be obtained than is the case for flask measurements or for ground-based measurements only. In particular, our data question the notion that there is usually anything like "well mixed background air" in the mid-to-high northern latitudes during the winter months.

Growth dynamics of conifer tree rings. Images of past and future environments
: монография / E. A. Vaganov, M. K. Hughes, A. V. Shashkin. - Berlin ; Heidelberg : Springer, 2006. - 358 с. : ил., табл. - (Ecological studies : analysis and Synthesis, ISSN 0070-8356 ; vol. 183). - Библиогр.: с. 311-342. - ISBN 3-540-26086-2 : Б. ц.
Аннотация: Each tree ring contains an image of the time when the ring formed, projected onto the ring's size, structure, and composition. Tree rings thus are natural archives of past environments, and contain records of past climate. While dendrochronologists have investigated the impact of climate on tree-ring growth by empirical-statistical methods. This volume presents a process-based model complementing previous approaches. Basic ideas concerning the biology of tree-ring growth and its control by environmental factors are treated, especially for conifers. The use of the model is illustrated by means of several examples from widely differing environments, and possible future directions for model development and application are discussed. The volume provides an improved mechanistic basis for the interpretation of tree rings as records of past climate. It advances process understanding of the large-scale environmental control of wood growth. As forests are the main carbon sink on land, the results are of great importance for all global change studies.

Particulate emissions from fires in central Siberian Scots pine forests
: материалы временных коллективов / Yu. N. Samsonov [и др.] // Canadian Journal of Forest Research. - 2005. - Vol. 35, № : 9. - С. 2207-2217
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.

The structure and biodiversity after fire disturbance

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.

: материалы временных коллективов / С. Ю. Евграфова, О. Б. Шибистова, Г. К. Зражевская и др. // Известия РАН. Серия биологическая. - 2008. - № 5. - С. 528-534. - Библиогр. в конце ст.
Перевод заглавия: Phospholipid fatty acid composition of microorganisms in pine forest soils of Central Siberia
Аннотация: Исследован состав жирных кислот (ЖК) фосфолипидов мембран клеточных стенок микроорганизмов в подзолистых почвах сосняков Средней Сибири. Отмечено плавное снижение живой микробной биомассы в исследуемом минеральном слое почвы от поверхности до глубины 1 м. Несмотря на падение биомассы в два раза на нижних горизонтах, ее уровень оставался достаточно высоким - 12-14 нмольЖК/г почвы. Коэффициент сходства композиций жирных кислот почв облесненного и необлесненного участков составлял 0.85. Коэффициент богатства ЖК снижался с глубиной минерального слоя почвы с одновременным увеличением различий в профилях жирных кислот.

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).

Южное Прибайкалье -- низовые пожары -- радиальный прирост деревьев -- напочвенный покров -- органогенные пирогенные горизонты почв
Аннотация: Проанализированы данные экспериментальных исследований по послепожарной динамике лесов в Южном Прибайкалье. Установлено, что низовые пожары подстилочно-гумусового вида в засушливые годы являются основным деструктивным фактором в динамике кедровых лесов. Воздействие низового огня сопровождается усыханием деревьев, а жизнеспособность выживших после пожаров кедров зависит от характера и тяжести огневых повреждений. Приведена характеристика нижних ярусов растительности и ее динамика под влиянием пожаров разной интенсивности. Показано негативное воздействие низовых пожаров на изменение запаса, качественного фракционного состава органогенных горизонтов почв и их химического состава. We examine the data from experimental investigations into the post-fire dynamics of Siberian stone pine forests in Southern Cisbaikalia. The analysis revealed that creeping fires of the litter-humus type in dry years constitute the main destructive factor in the dynamics of Siberian stone pine forests. Creeping fires involve desiccation of trees, while viability of Siberian stone pine trees that have survived the fire depends on the character and severity of fire-related tree injuries. We provide a characteristic of the lower layers of vegetation and its dynamics under the influence of fires of different intensities. It is shown that creeping fires have a negative influence on changes in reserves, qualitative fiber length distribution of organogenic soil horizons, and on their chemical composition.

swamp -- peat deposit -- pollen analysis -- climate and vegetation reconstruction -- forest cover dynamics -- Holocene
Аннотация: A reconstruction of forest-cover dynamics in the northern part of the Kas River basin has been done for the first time. This study based on a palynological analysis of the peat profile. Six pollen zones and respective phases of forest evolution are distinguished. It is inferred that changes in the forest species composition over the last 8000 years were determined by variations in the global and regional climate. The warm and humid climate of the Atlantic period promoted the development of dark coniferous birch-spruce-fir forests. Cooling and smaller precipitation in the Subboreal period led to a change in dominant species to Scotch pine and birch-Siberian pine forests with an admixture of spruce and fir. In the Subatlantic period, closed coniferous forests eventually evolved, with Siberian pine-pine remaining dominant.

Аннотация: Arctic environments, where surface temperatures increase and sea ice cover and permafrost depth decrease, are very sensitive to even slight climatic variations. Placing recent environmental change of the high-northern latitudes in a long-term context is, however, complicated by too short meteorological observations and too few proxy records. Driftwood may represent a unique cross-disciplinary archive at the interface of marine and terrestrial processes. Here, we introduce 1445 driftwood remains from coastal East Greenland and Svalbard. Macroscopy and microscopy were applied for wood anatomical classification; a multi-species subset was used for detecting fungi; and information on boreal vegetation patterns, circumpolar river systems, and ocean current dynamics was reviewed and evaluated. Four conifer (Pinus, Larix, Picea, and Abies) and three deciduous (Populus, Salix, and Betula) genera were differentiated. Species-specific identification also separated Pinus sylvestris and Pinus sibirica, which account for similar to 40% of all driftwood and predominantly originate from western and central Siberia. Larch and spruce from Siberia or North America represents similar to 26% and similar to 18% of all materials, respectively. Fungal colonization caused different levels of driftwood staining and/or decay. Our results demonstrate the importance of combining wood anatomical knowledge with insight on boreal forest composition for successfully tracing the origin of Arctic driftwood. To ultimately reconstruct spatiotemporal variations in ocean currents, and to better quantify postglacial uplift rates, we recommend consideration of dendrochronologically dated material from many more circumpolar sites.

Аннотация: A typological series of native Betula pubescens Ehrh. dendrocenoses along the channel of a river crossing a bog was studied. The variability of the mineral element reserves is described by geostatistical methods as the sum of a trend, autocorrelation, and random components. The contribution of deterministic and random components has been assessed in the years with average precipitation and in the year of 2007 with high and long-term flooding. The empirical variograms and the parameters of the model variograms are presented. The class of the spatial correlation of the ash reserves is described. A primary cause of the ash content's variability is the specific water regime, which is determined by the following: (i) the abundance and duration of the spring floods responsible for the silt mass brought by the river and (ii) the draining effect of the intrabog river, the distance from which provided the formation in the forest of the ground cover with the specific species composition and ash content. The falloff of the arboreal layer in the bog birch forests formed the fundamental mineral background of the litter.

Аннотация: The microbial activity of peat soils was studied in boggy larch forests and in an oligo-mesotrophic bog in the basins of the Kochechum and Nizhnaya Tunguska rivers (central Evenkia). It was found that the organic matter transformation in the peat soils of all the plots is mainly performed by oligotrophic bacteria composing 88-98% of the total bacterial complex. The major contribution to the organic matter destruction belonged to the heterotrophic microorganisms, the activity of which depended on the permafrost depth and the soil temperature, the soil acidity, and the botanical composition of the peat. Peat soils were characterized by different activities as judged from their microbiological and biochemical parameters. The functioning of microbial communities in the studied ecotopes of the permafrost zone was within the range of natural variations, which pointed to their ecological stability.
