Аннотация: The developmental history of peatland and dry land vegetation within the Ob-Vasugan watershed of Western Siberia was characterized according to features of the plant communities and climatic changes which were revealed by stratigraphic, spore-pollen and C-14 (carbon) data obtained from a vertical peat profile 'Vodorasdel'. Changes in the paleoecological environment over the last 10000 years were divided into five periods. The climate was characterized in the Holocene according to these periods. At the watershed studied, peatland-forming processes started about 9510 years ago resulting in 550 cm of peat accumulation. The rate of peat accumulation within the watershed decreased over time from 1.9-0.3 mm year(-1).

Net ecosystem productivity and peat accumulation in a Siberian Aapa mire
/ E. -D. Schulze, A. S. Prokushkin, E. A. Vaganov // Tellus. Series B: Chemical and physical meteorology. - 2002. - Vol. 54B, № 5. - С. 531-536
Аннотация: Net ecosystem productivity (NEP) was studied in a bog located in the middle taiga of Siberia using two approaches, the accumulation of peat above the hypocotyl of pine trees, and the eddy covariance flux methodology. NEP was 0.84 tC ha(-1) yr(-1) using the peat accumulation method; it was 0.43-0.62 tC ha(-1) yr(-1) using eddy covariance over three growing seasons. These data were compared with NEP of the surrounding forest, which was 0.6 tC +/- 1.1 hat yr(-1). The trees growing on the bog reached a total height of about 3 m and an age of 80-120 yr when peat accumulation reached 0.5-0.6 m. At that stage the growth rate of the oldest trees declined. This indicates that there is a maximum age that can be reached by trees growing on hummocks (150 yr), depending on conditions. The data show that the determination of NEP in bogs by using the peat accumulation above the hypocotyl is a useful method which can be applied on a wide range of bog types, but it may systematically overestimate NEP. The total sink capacity for carbon assimilation of bogs is comparable to that of forest, although methane emissions and losses of dissolved organic carbon must be taken into account when assessing the regional carbon cycle.

Seasonal and annual variations in the photosynthetic productivity and carbon balance of a central Siberian pine forest
/ J. Lloyd, O. Shibistova et al // Tellus. Series B: Chemical and physical meteorology. - 2002. - Vol. 54B, № 5. - С. 590-610
Аннотация: We present a first analysis of data (June 1998 to December 2000) from the long-term eddy covariance site established in a Pinus sylvestris stand near Zotino in central Siberia as part of the EUROSIBERIAN CARBONFLUX project. As well as examining seasonal patterns in netecosystem exchange (N-E), daily, seasonal and annual estimates of the canopy photosynthesis (or gross primary productivity, G(P)) were obtained using N-E and ecosystem respiration measurements. Although the forest was a small (but significant) source of CO2 throughout the snow season (typically mid-October to early May) there was a rapid commencement of photosynthetic capacity shortly following the commencement of above-zero air temperatures in spring: in 1999 the forest went from a quiescent state to significant photosynthetic activity in only a few days. Nevertheless, canopy photosynthetic capacity was observed to continue to increase slowly throughout the summer months for both 1999 and 2000, reaching a maximum capacity in early August. During September there was a marked decline in canopy photosynthesis which was only partially attributable to less favourable environmental conditions. This suggests a reduction in canopy photosynthetic capacity in autumn, perhaps associated with the cold hardening process. For individual time periods the canopy. photosynthetic rate was mostly dependent upon incoming photon irradiance. However, reductions in both canopy conductance and overall photosynthetic rate in response to high canopy-to-air vapour differences were clearly evident on hot dry days. The relationship between canopy conductance and photosynthesis was examined using Cowan's notion of optimality in which stomata serve to maximise the marginal evaporative cost of plant carbon gain. The associated Lagrangian multiplier (lambda) was surprisingly constant throughout the growing season. Somewhat remarkably, however, its value was markedly different between years, being 416 mol mol(-1) in 1999 but 815 mol mol(-1) in 2000. Overall the forest was a substantial sink for CO2 in both 1999 and 2000: around 13 Mol C m(-2) a(-1). Data from this experiment, when combined with estimates of net primary productivity from biomass sampling suggest that about 20% of this sink was associated with increasing plant biomass and about 80% with an increase in the litter and soil organic carbon pools. This high implied rate of carbon accumulation in the litter soil organic matter pool seems unsustainable in the long term and is hard to explain on the basis of current knowledge.

Biochemistry of carbon and nitrogen in the Siberian Afforestation Experiment
: материалы временных коллективов / E. F. Vedrova // Tree species effects on soils: implications for global change. - 2005. - С. 281-292. - Библиогр. в конце ст.
Аннотация: We evaluated parameters (stock and flux) carbon, nitrogen and ash element cycling in the plant-soil system. The study was performed in arolla pine, Scots pine, Siberian larch, Norway spruce, aspen and birch plantations established on Kemchug upland, Chulym-Yenisei denudational plain, in 1968-1972. Young ecosystems (age class 2) that have developed under relatively similar environmental conditions have thus accumulated different amounts of organic and mineral matter in biomass and detritus, mainly due to differences in major woody species characteristics. All ecosystems are a net atmosperic carbon sink, with a pooling rate of 1.81-4.43 t C ha -1 yr -1. The sink (NEP) is made up by C accumulation in stand biomass production, vegetation detritus, and soil humus and accounts for 46-76% of the total C allocated in annual increment; the main componentt is net C flux to biomass. The rate of N-min flux from soil pool to NPP is in fact in balance with that soil N-min accumulation in the arolla pine, larch, spruce, and birch plots. In addition, the ecosystems are characterized by a transitional cycling regime evident through non-balanced controlling organic and mineral matter stored in "plant-soil" system blocks.

Аннотация: While the forest-tundra zone in Siberia, Russia has been dendroclimatologically well-studied in recent decades, much less emphasis has been given to a wide belt of northern taiga larch forests located to the south. In this study, climate and local site conditions are explored to trace their influence on radial growth of Gmelin larch (Larix gmelinii (Rupr.) Rupr.) trees developed on permafrost soils in the northern taiga. Three dendrochronological sites characterized by great differences in thermo-hydrological regime of soils were established along a short (ca. 100 m long) transect: on a river bank (RB), at riparian zone of a stream (RZ) and on a terrace (TER). Comparative analysis of the rate and year-to-year dynamics of tree radial growth among sites revealed considerable difference in both raw and standardized tree-ring width (TRW) chronologies obtained for the RZ site, characterized by shallow soil active layer depth and saturated soils. Results of dendroclimatic analysis indicated that tree-ring growth at all the sites is mostly defined by climatic conditions of a previous year and precipitation has stronger effect on TRW chronologies in comparison to the air temperatures. Remarkably, a great difference in the climatic response of TRW chronologies has been obtained for trees growing within a very short distance from each other. The positive relation of tree-ring growth with precipitation, and negative to temperature was observed in the dry site RB. In contrary, precipitation negatively and temperature positively influenced tree radial growth of larch at the water saturated RZ. Thus, a complicate response of northern Siberian larch forest productivity to the possible climate changes is expected due to great mosaic of site conditions and variability of environmental factors controlling tree-ring growth at different sites. Our study demonstrates the new possibilities for the future dendroclimatic research in the region, as various climatic parameters can be reconstructed from tree-ring chronologies obtained for different sites.

Аннотация: While the forest-tundra zone in Siberia, Russia has been dendroclimatologically well-studied in recent decades, much less emphasis has been given to a wide belt of northern taiga larch forests located to the south. In this study, climate and local site conditions are explored to trace their influence on radial growth of Gmelin larch (Larix gmelinii (Rupr.) Rupr.) trees developed on permafrost soils in the northern taiga. Three dendrochronological sites characterized by great differences in thermo-hydrological regime of soils were established along a short (ca. 100 m long) transect: on a river bank (RB), at riparian zone of a stream (RZ) and on a terrace (TER). Comparative analysis of the rate and year-to-year dynamics of tree radial growth among sites revealed considerable difference in both raw and standardized tree-ring width (TRW) chronologies obtained for the RZ site, characterized by shallow soil active layer depth and saturated soils. Results of dendroclimatic analysis indicated that tree-ring growth at all the sites is mostly defined by climatic conditions of a previous year and precipitation has stronger effect on TRW chronologies in comparison to the air temperatures. Remarkably, a great difference in the climatic response of TRW chronologies has been obtained for trees growing within a very short distance from each other.

Soil formation in the technogenic forest-steppe landscapes of the Nazarovskaya Depression in western Siberia

Аннотация: The soil formation was studied in the 21- to 35-year-old pine plantations created on the overburden dumps of the Nazarovskaya Depression without applying the material of the humus horizon. The surface technogenic formations under the pine plantations belong to the group of naturfabricats (surface formations devoid of the humus horizon and composed of natural substrate). The morphological characteristics, bulk chemical and particle-size compositions, and labile properties of the soils indicate that the accumulation and transformation of organic matter are dominant processes in the artificially planted forests. The accumulation of organic residues and destruction and humification are tightly related to the environmental conditions transformed by the technogenesis and conceal other processes forming the soil profiles. Quasizems created for agricultural production purposes were the objects of the study. They were formed by covering the technically planned overburden rocks with the material of humus layers. The thickness of the humus horizons of the quasizems varies greatly (25-64%); the variation of the humus reserves in them is 34-122%. Middle-profile horizons have not been formed by the present time.

Defense response of pine stem phloem to wounding and treatment with mycelial extracts from Ceratocystis laricicola

Аннотация: Ophiostomatoid fungi colonize the conducting tissues of conifer stems, the phloem and the xylem. These pathogenic fungi penetrate into the stem through injuries made by xylophagous insects vectoring these pathogens. In this study the response of the phloem of Scotch pine (Pinus sylvestris L.) to wounding (treatment 1) was compared with the response to wounding combined with application of high-molecular-weight compounds isolated from the mycelium of the ophiostomatoid fungus Ceratocystis laricicola Redfern & Minter (treatment 2). Both treatments induced the appearance of necrosis in the inner bark, the formation of periderm separating living and dead tissues, and formation of the callus alongside the wound perimeter. In addition, the bark accumulated lignin, bound proanthocyanidins, and resins, with a parallel decrease in the content of free proanthocyanidins, low-molecular-weight carbohydrates, and non-lignin components of the cell wall (P > 0.95). The size of necrotic spots, as well as changes in the content of most substances, were significantly higher in the treatment 2 than in the treatment 1 (P > 0.95). The accumulation of lignin in cell walls of phloem sieve cells was delayed in the treatment 2 as compared with that in the treatment 1. This suggested that the mycelial extract temporarily inhibited lignification at the early stage of the wound response. This disturbance of the cell wall protective transformation led to the hypothesis that the fungal suppressors retard the repair of inner bark injured by insects, thereby favoring the invasion of conifer tissues by ophiostomatoid fungi.

Аннотация: This paper analyses aerosol particle number size distributions, particulate absorption at 570 nm wavelength and carbon monoxide (CO) measured between September 2006 and January 2010 at heights of 50 and 300 m at the Zotino Tall Tower Facility (ZOTTO) in Siberia (60.8 degrees N; 89.35 degrees E). Average number, surface and volume concentrations are broadly comparable to former studies covering shorter observation periods. Fits of multiple lognormal distributions yielded three maxima in probability distribution of geometric mean diameters in the Aitken and accumulation size range and a possible secondary maximum in the nucleation size range below 25 nm. The seasonal cycle of particulate absorption shows maximum concentrations in high winter (December) and minimum concentrations in mid-summer (July). The 90th percentile, however, indicates a secondary maximum in July/August that is likely related to forest fires. The strongly combustion derived CO shows a single winter maximum and a late summer minimum, albeit with a considerably smaller seasonal swing than the particle data due to its longer atmospheric lifetime. Total volume and even more so total number show a more complex seasonal variation with maxima in winter, spring, and summer. A cluster analysis of back trajectories and vertical profiles of the pseudo-potential temperature yielded ten clusters with three levels of particle number concentration: Low concentrations in Arctic air masses (400-500 cm(-3)), mid-level concentrations for zonally advected air masses from westerly directions between 55 degrees and 65 degrees N (600-800 cm(-3)), and high concentrations for air masses advected from the belt of industrial and population centers in Siberia and Kazakhstan (1200 cm(-3)). The observational data is representative for large parts of the troposphere over Siberia and might be particularly useful for the validation of global aerosol transport models.

Аннотация: The stock and structure of organic substances in the pine tree plantations on the overburden dumps of open-cut coal mines in Middle Siberia have been determined. It has been shown that the forming forest biogeocenoses differ from the natural phytocenoses and soils of the forest landscapes in the structure of the carbon pool and its distribution between the vegetation and soil components. In artificial forest ecosystems, the bulk of the plant component is accumulated in the aboveground part of the forest stand (40-59%). The aboveground grass cover contains only 0.1-1.4% of the total phytomass stock of the ecosystem. The annual accumulation of organic substances in the initial soils amounts to 0.28-1.45 t/ha.

Аннотация: Comprehensive stratigraphic analyses of a standard peat profile laid on a large oligotrophic bog in the interfluve of Kas and Sym rivers, left tributaries of the Yenisei River, allowed reconstruction of local vegetation change and hydrological regime over a period of seven thousand years. The established three stages in vegetation succession in a local bog correspond to different degree of humidification. The development of bog ecosystem is found to be scarcely affected by regional climate. The process and rate of peat accumulation varied in different periods of the Holocene. The average rate of peat accumulation in the profile was 0.88 mm/year.
