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.

Climatic control of stand thinning in unmanaged spruce forests of the southern taiga in European Russia
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.

Interannual and seasonal variations of energy and water vapour fluxes above a Pinus sylvestris forest in the Siberian middle taiga
/ N.M. Tchebakova et al, O. Shibistova // Tellus. Series B: Chemical and physical meteorology. - 2002. - Vol. 54B, № 5. - С. 537-551
Аннотация: Long-term eddy covariance measurements of energy and water fluxes and associated climatic parameters were carried out above a Scots pine (Pinus sylvestris) forest in the middle taiga zone of Central Siberia. Data from June 1998 through October 2000 are presented. With the exception of winter 1998/1999, data collection over this period were more or less continuous. A distinct seasonality in surface energy exchange characteristics was observed in all years. In early spring in the absence of physiological activity by the vegetation, about 80% of the net radiation was partitioned for sensible heat, resulting in Bowen ratios, beta, as high as 8. In the 1-2 wk period associated with onset of photosynthesis in spring, evaporation rates increased rapidly and beta rapidly dropped. However, even during summer months, sensible heat fluxes typically exceeded latent heat fluxes and beta remained above 2.0. Observed daily evaporation rates varied between 0.5-1.0 mm d(-1) in spring and autumn and 1.5-2 mm d(-1) in midsummer. The overall average for the three growing seasons examined was 1.25 mm d(-1). Precipitation was on average 230 mm for the growing period, with evaporation over the same time being about 190 mm for both 1999 and 2000. This represented only about 35% of the equilibrium evaporation rate. There was typically a positive hydrological balance of 40 mm for the growing season as a whole. However, in all three years examined, evaporation exceeded precipitation totals by 20-40 mm in at least one calendar month during summer. During the growing season, daily averaged surface conductances varied between 0.15 and 0.20 mol m(-2) s(-1) (3-4.5 mm s(-1)) in dry or cool months and 0.30-0.35 mol m(-2) s(-1) (6.5-8 mm s(-1)) in moist and warm months. Despite a negative hydrological balance during midsummer, there was little evidence for reduced canopy conductances in response to soil water deficits. This may have been the consequence of roots accessing water from within or just above a perched water table, located at about 2 m depth.

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.

Аннотация: We measured annual ring with of larch trees growing on the contrasing north-and south-facing slopes. Moreover, we also examined wood anatomy of stems of larch seedlings raised under high CO2 in phytotron for two years. Based on these results, we can predict the effect of greenhouse condition on the annual ring formation of larch species.

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.

Intraspecific response of Scots pine (Pinus silvestris L.) to pathogens in a provenance trial in Middle Siberia
: материалы временных коллективов / N. A. Kuzmina, Sergey R. Kuz'min // Eurasian Journal of Forest Research. - 2008. - Vol. 11-2. - С. 51-59. - Библиогр. в конце ст.
Аннотация: The results of assessing the resistance of 84 Scotch pine climatypes, growing in a provenance trial in a taiga zone of Middle Siberia, to pathogens of needle cast (Lophodermium pinastri Chev.), snow blight (Phacidium infestans Karst.), Cenangium diebak (Cenangium ferruginosum Fr.: Fr.) and rust (cronartium flaccidum (Alb. et Schw.) Wint and Peridermium pini (Pers.) Lew. et Kleb). The dynamics of the diseases caused by these pathogens are shown for 30-year period. The authors found that Scotch pine resistance to the pathogens in the provenance trial depended both on ecological regime of the growing site and on the genetic peculiarities of the climatypes determined by their site of origin. Differences in the resistance of the same Scotch pine climatypes to the pathogens showed itself when growing them on different ecological backgrounds (on sandy soil - the bear berry pine forest type, and on dark-grey forest soil - the tall-herb pine forest (type). Climatypes of "northern Lapponian" and "Siberian" pine subspecies are more tolerant to the pathogens.

Аннотация: The results of assessing the resistance of 84 Scotch pine climatypes, growing in a provenance trial in a taiga zone of Middle Siberia, to pathogens of needle cast (Lophodermium pinastri Chev.), snow blight (Phacidium infestans Karst.), Cenangium diebak (Cenangium ferruginosum Fr.: Fr.) and rust (cronartium flaccidum (Alb. et Schw.) Wint and Peridermium pini (Pers.) Lew. et Kleb). The dynamics of the diseases caused by these pathogens are shown for 30-year period. The authors found that Scotch pine resistance to the pathogens in the provenance trial depended both on ecological regime of the growing site and on the genetic peculiarities of the climatypes determined by their site of origin. Differences in the resistance of the same Scotch pine climatypes to the pathogens showed itself when growing them on different ecological backgrounds (on sandy soil - the bear berry pine forest type, and on dark-grey forest soil - the tall-herb pine forest (type). Climatypes of "northern Lapponian" and "Siberian" pine subspecies are more tolerant to the pathogens.

Evidence of evergreen conifers invasion into larch dominated forests during recent decades
: материалы временных коллективов / V. I. Kharuk, K. J. Ranson, M. L. Dvinskaya // Environmental change in Siberia: earth observation, field studies and modelling. - Dordrecht et. al. : Springer, 2010. - С. 53-65. - Библиогр. в конце ст.
Аннотация: The results obtained indicate a DNC and birch invasion into a traditional larch domination zone, and the connection of this phenomenon with climatic trends during last decades. On the western and southern margions DNC regeneration formed a second layer in the forest canopies, which could eventually replace the larch in the overstory. Larch as a species also responds to climatic trends: its radial increment significantly increased during last 3 decades, and this increase correlates with summer temperatures and precipitation. The other larch response is the migration into the trundra zone and a crown closure increase, as was found on the key-sites "Polar Ural"and "Ary-Mas". The resulting effect of this process may be that larch could reach the Arctic shore, a phenomenon that has happened in a former epoch, whereas the traditional area of larch dominance will turn to mixed taiga forest.

Potencial climate-induced vegetation change in Siberia in the twenty-first century
: материалы временных коллективов / N. M. Tchebakova, E. I. Parfenova, A. J. Soja // Environmental change in Siberia: earth observation, field studies and modelling. - Dordrecht et. al. : Springer, 2010. - С. 67-82. - Библиогр. в конце ст.
Аннотация: Analyses demonstrate the far-reaching effects of a changing climate on vegetation cover. Hot spots of potential Siberian vegetation change are predicted for 1990. Observations of vegetation change in Siberia have already been documented in the literature. Vegetation habitats should be significantly perturbed by 2020, and markedly perturbed by 2080. Because of a dryer climate, forest-steppe and steppe-ecosystems, rather than forests, are predicted to dominate central Siberian landscapes. Despite the predicted increase in warming, permafrost is not predicted to thaw deep enough to support dark taiga over the Siberian plain, where the larch taiga will cntinue to be the dominant zonobiome. On the contrary, in the southern mountains in the absence of permafrost, dark taiga is predicted to remain the dominant orobiome.

Wildfire dynamics in mid-siberian larch dominated forests
: материалы временных коллективов / V. I. Kharuk, K. J. Ranson, M. L. Dvinskaya // Environmental change in Siberia: earth observation, field studies and modelling. - Dordrecht et. al. : Springer, 2010. - С. 83-100. - Библиогр. в конце ст.
Аннотация: The long-term wildfire dynamics, including fire return interval (FRI), in the zone of larch dominance and the "larch-mixed taiga" ecotone were examined. A wildfire chronology encopassing the fifteenth through the twentieth centuries was developoed by analyzing tree stem fire scars. Average FRI determined from stem fire scar dating was 82 +,- 7 years in the zone of larch dominance. FRI was found to be dependent on site topography. FRI on north-east facing slopes in the zone of larch dominance was 86 +,- 11 years. FRI was siignificantly less on south-west facing slopes at 61 +,- 8 years and flat terrain at 68 +,- 14 years. The implications of the observed trends on the larch community are discussed.

Аннотация: The major parameters of the carbon cycle were studied in the pine stands of green moss and lichen proups of forest type using biometric method. The study was carried out for stands age sequence (15-260 years old) in the Zotinskii experimental polygon of Yenisei Transect. Heterotrophic respiration changes a little with age of the pine stands, therefore, net ecosystem production of these stands, in generally, mainly determines by age changes in the net primary production intensity.

Sukachev Institute of forest SB RAS, 2011. - С. 105-107. - Библиогр. в конце ст.
Аннотация: The Siberian moth is the main ecological factor that initiates succession in the dark coniferous forest in taiga subzone of Southern Siberia. Subsequent wildfires only further modify the process of reforestation in "shelkopryadniks". A review of investignations of the Siberian moth outbreak of 1989-1997 demonstrates different ecological and economic consequences of the global ecological phenomenon.
