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.

Climatic control of stand thinning in unmanaged spruce forests of the southern taiga in European Russia
/ N.N. Vygodskaya, E.-D. Schulze, N.M. Tchebakova et al // Tellus. Series B: Chemical and physical meteorology. - 2002. - Vol. 54B, № 5. - С. 443-461
Аннотация: The demography of Picea abies trees was studied over a period of about 30 yr on permanent plots in six forest types of an unmanaged forest located in a forest reserve of the Southern Taiga, NW of Moscow. This study encompassed a broad range of conditions that are typical for old growth spruce forests in the boreal region, including sites with a high water table and well drained sites, podzolic soils, acidic soils and organic soils. At all sites stand density, tree height, breast height diameter and age has been periodically recorded since 1968. Tree density ranged between 178 and 1035 trees ha(-1) for spruce and between 232 and 1168 trees ha-1 for the whole stand, including mainly Betula and Populus. Biomass ranged between 5.4 and 170 t(dw) ha(-1) for spruce and between 33 to 198 td, ha(-1) for the whole stand. Averaged over a long period of time, biomass did not change with stand density according to the self-thinning rule. in fact, on most sites biomass remained almost constant in the long term, while stand density decreased. The study demonstrates that the loss of living trees was not regulated by competitive interactions between trees, but by disturbances caused by climatic events. Dry years caused losses of minor and younger trees without affecting biomass. In contrast, periodic storms resulted in a loss of biomass without affecting density, except for extreme events, where the whole stand may fall. Dry years followed by wet years enhance the effect on stand density. Since mainly younger trees were lost, the apparent average age of the stand increased more than real time (20% for Picea). Average mortality was 2.8 +/- 0.5% yr(-1) for spruce. Thus, the forest is turned over once every 160-180 yr by disturbances. The demography of dead trees shows that the rate of decay depends on the way the tree died. Storm causes uprooting and stem breakage, where living trees fall to the forest floor and decay with a mean residence time (t(1/2)) of about 16 yr (decomposition rate constant k(d) = 0.042 yr(-1)). This contrasts with trees that die by drought or insect damage, and which remain as standing dead trees with a mean residence time of 3-13 yr until they are brought to ground, mainly by wind. These standing dead trees require an additional mean residence time of about 22 yr for decay on the ground (k(d) = 0.031). In conclusion, we demonstrate that, rather than competitive interactions, it is climate extremes, namely drought, rapid changes of dry years followed by wet years, and storm that determine stand structure, biomass and density, which then affect the net exchange with the atmosphere. The climatic effects are difficult to predict, because the sensitivity of a stand to climate extremes depends on the past history. This may range from no effect, if the stand was recovering from an earlier drought and exhibited a relatively low density, to a total collapse of canopies, if drought reduces stand density to an extent that other climatic extremes (especially wind) may cause further damage.

Soil and canopy CO2, 13CO2, H2O and sensible heat flux partitions in a forest canopy inferred from concentration measurements
/ J.M. Styles et al, O. Shibistova // Tellus. Series B: Chemical and physical meteorology. - 2002. - Vol. 54B, № 5. - С. 655-676
Аннотация: A canopy scale model is presented that utilises Lagrangian dispersal theory to describe the relationship between source distribution and concentration within the canopy. The present study differs from previous studies in three ways: (1) source/sink distributions are solved simultaneously for CO2, (CO2)-C-13, H2O and sensible heat to find a solution consistent with leaf-level constraints imposed by photosynthetic capacity, stomatal and boundary layer conductance, available energy and carbon isotopic discrimination during diffusion and carboxylation; (2) the model is used to solve for parameters controlling the nonlinear source interactions rather than the sources themselves; and (3) this study used plant physiological principles to allow the incorporation of within- and above-canopy measurements of the C-13/C-12 ratios Of CO2 as an additional constraint. Source strengths Of CO2, H2O, sensible heat and (CO2)-C-13 within a Siberian mixed-coniferous forest were constrained by biochemical and energy-balance principles applied to sun and shaded leaves throughout the canopy. Parameters relating to maximum photosynthetic capacity, stomatal conductance, radiation penetration and turbulence structure were determined by the optimisation procedure to match modelled and measured concentration profiles, effectively inverting the concentration data. Ground fluxes Of CO2, H2O and sensible heat were also determined by the inversion. Total ecosystem fluxes predicted from the inversion were compared to hourly averaged above-canopy eddy covariance measurements over a ten-day period, with good agreement. Model results showed that stomatal conductance and maximum photosynthetic capacity were depressed due to the low temperatures experienced during snow melt; radiation penetrated further than simple theoretical predictions because of leaf clumping and penumbra, and stability effects were important in the morning and evening. The inversion was limited by little vertical structure in the concentration profiles, particularly of water vapour, and by co-dependence of canopy parameters.

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.

Genetic and environmental signals in tree rings from different provenances of PINUS SYLVESTRIS L. planted in the southern taiga, Central Siberia
/ Y. Savva, F. Schweingruber, L. I. Milyutin, E. Vaganov // Trees. Structure and Function. - 2002. - Vol. 16, № 4-5. - С. 313-324
Аннотация: Seeds of Scots pine provenances originating from all over Russia were planted in the Boguchany provenance trial at a central Siberian location (southern taiga) in 1974. Eight tree-ring density and width parameters for 16 different provenances were measured with densitometric techniques. The tree-ring data were recorded from 1982 to 1996. Correlation analysis calculated by raw series showed that tree-ring width decreases and percentage of latewood increases with an increase in the latitude of the seed source. High variability was found for raw tree-ring characteristics from tree to tree within each provenance for an observed period (individual variability). The age trend of each tree is well described by the chosen fitting curve, and is similar for the mean series of each provenance. As a consequence of these findings, the indexed chronology for each provenance mainly shows climatic signals. The SD of the indexed chronology (chronological variability) is low for each provenance, showing low sensitivity to climatic influences. A cluster analysis of provenances represented by tree-ring characteristics differentiated the provenances into three groups. However, the statistical distance between the groups was minor. So we can confirm that Scots pine provenances are highly adaptable to local ecological conditions and regional climatic influences.

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.

Genetic diversity, structure and differentiation of Gmelin Larch (Larix gmelinii (Rupr.) Rupr.) populations from Central Evenkia and Eastern Zabaikalje
: материалы временных коллективов / N. V. Oreshkova [и др.] // Eurasian journal of forest research. - 2006. - Vol. 9-1. - С. 1-8
Аннотация: As a results of studies conducted it was established that genetic diversity and structure of L. gmelinii populations in Central Evenkia and in Eastern Zabaikalje are significantly distinguished. The mean genetic distance D between populations from these regions calculated on the basis of allelic frequencies 17 isoenzyme loci is equal to 0.03. The review of data at genetic diversity and intraspesific differentiation of conifer species showed that such extent of genetic differentiation is characteristic of geographical races of single species. On this basis we concluded that L. gmelinii populations from Central Evenkia and Eastern Zabaikalje are genetically isolated and can be regarded as geographical races. The data obtained confirm the supposition of Abaimov and Milyutin that L. gmelinii, growing in various on natural conditions regions within the limits of its vast area, has to subdivide into more small intraspecific taxons. Results of our studies represent only a part of the total work that is necessary to fully assess the variability of this species.

Interannual growth response of Norway spruce to climate along an altitudinal gradient in the Tatra Mountains, Poland
: материалы временных коллективов / Y. Savva, E. A. Vaganov et al. // Trees. Structure and function. - 2006. - Vol. 20, № 6. - С. 735-746. - Библиогр. в конце ст.
Аннотация: Ring-width chronologies of Picea abies (L.) Karst. from ten sites in the Tatra Mountains, Poland, were developed to explore growth/climate responses in stands along an altitudinal gradient ranging from 839 to 1468 m a.s.l. There were positive relationships between current-year radial growth and mean monthly temperatures in March, April, June, July, but with increasing elevation, the strength of this correlation declined for March-April and increased for June-July temperatures.The mean monthly temperature in October of the previous year positively influenced radial growth of trees at all sites. Lower mean temperatures in January negatively affected growth of trees at high-elevation sites. Trees at the low-elevation sites responded positively to a warm early spring, whereas trees at high-elevation sites showed positive growth responses to higher summer temperatures.

Аннотация: Variations in the succession following cutting of a herbaceous Larix sibirica Ledeb. phytocoenosis along the southern boundary of boreal forests in southern Siberia and in Eastern Hentey, Mongolia, were studied. Morphometric methods were used to determine the dimensional hierarchies of coenopopulation individuals. Structure and productivity of the aboveground components including standing wood, herbaceous cover and litter were studied. The maximum aboveground phytomass was measured.

Separating the climatic signal from tree-ring width and maximum latewood density records
: материалы временных коллективов / // Trees. Structure and Function. - 2007. - Т. 21, № 1. - С. 37-44. - Библиогр. в конце ст.
Аннотация: We propose a technique for separating the climatic signal which is contained in two tree-ring parameters widely used in dendroclimatology. The method is based on the removal of the relationship between tree-ring width and maximum latewood density observed for narrow tree rings from high latitudes. The new technique is tested on data from three larch stands located along the northern timberline in Eurasia. The analysis confirms the great importance of summer temperature for tree radial growth and tree -ring formation. These results are consistent with the known dynamics of tree-ring growth in high latitudes and mechanisms of tree-ring growth in high latitudes and mechanisms of tree-ring formation.

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.
