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.

Seasonal and spatial variability in soil CO2 efflux rates for a central Siberian Pinus sylvestris forest
/ O. Shibistova et al, S. Efgrafova, G. Zrazhevskaya // Tellus. Series B: Chemical and physical meteorology. - 2002. - Vol. 54B, № 5. - С. 552-567
Аннотация: Rates of CO2 efflux from the floor of a central Siberian Scots pine (Pinus sylvestris) forest were measured using a dynamic closed chamber system and by a eddy covariance system placed 2.5 m above the forest floor. Measurements were undertaken for a full growing season: from early May to early October 1999. Spatial variability as determined by the chamber measurements showed the rate of CO2 efflux to depend on location, with rates from relatively open areas ("glades") only being about 50% those observed below or around trees. This was despite generally higher temperatures in the glade during the day. A strong relationship between CO2 efflux rate and root density was observed in early spring, suggesting that lower rates in open areas may have been attributable to fewer roots there. Continuous measurements with the eddy covariance system provided good temporal coverage. This method, however, provided estimates of ground CO2 efflux rate rates that were about 50% lower than chamber measurements that were undertaken in areas considered to be representative of the forest as a whole. An examination of the seasonal pattern of soil CO2 efflux rates suggests that much of the variability in CO2 efflux rate could be accounted for by variations in soil temperature. Nevertheless, there were also some indications that the soil water deficits served to reduce soil CO2 efflux rates during mid-summer. Overall the sensitivity of CO2 efflux rate to temperature seems to be greater for this boreal ecosystem than has been the case for most other studies.

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: To predict the future vegetation change and biomass production in Siberian "permafrost Taiga", we evaluate the temperature effects on the growth and gas exchange characteristic of dominant species of larch and spruce under the contrasting north- and south-facing slope in Tura Experiment Forest in eastern Siberia. Soil temperature at 0-5 cm depth of north-facing slope was 2-5C lower. Needle length of larch and spruce grown on north-facing slope was longer than on south-one. There was no difference in the needle density.

Reconstructing past stand density in even-aged Larix gmelinii monocultures: comparison of three approaches
: материалы временных коллективов / A. Osawa, A. P. Abaimov, O. A. Zyryanova // Proceedings of the seventh Symposium on the joint Seberian Permafrost studies between Japan and Russia in 1998. - Sapporo : Hokkaido University. - С. 21-24. - Библиогр. в конце ст.
Аннотация: Three methods were compared for reconstructing stand densisty in the past of a naturally growing Larix gmelinii forest in central Siberia. The first method assumed that the stand has been developing along the self-thinning line. The second approach used structutal characteristics of trees in the stand. The third method estimated stand density by aging every dead stem that was present at the time of the study. We suggest that the third approach is most accurate, and current knowledge of the self-thinning relatioship is unsufficient for this species.

The influence of stand density on growth of three conifer species

Аннотация: We evaluated the influence of stand density on the growth and development of monoculture plantations of Scots pine, larch and Norway spruce. The planting density ranged from 500 to 128,000 trees/ha. After 22 years, tree height was not affected by density, though the height of pine and larch (8m) was greater than spruce (6m). Diameter declined exponentially with increasing density, but the slope was too low to offset the contribution of more trees to the stand total basal area and stem volume. Basal area and stem volume per hectare were greatest at the most extreme density for all three species, refuting ideas of "stagnation" at high density.

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.

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.

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.

Integrated approach to monitoring of the Siberian moth population density
: absracts / V. M. Pet'ko [и др.] // Enviromis. International conference on enviromental observations, modelling and information systems, Tomsk, Russia, July 1-8, 2006: program and abstracts. - 2006. - С. 95
Аннотация: The Siberian moth (SM), is the most destructive defoliator of conifers in Northern Asia. It could have a serious impact on native forests. The present day monitoring methods of SM populations density, based on trees shaking for larve sampling, are labor-intensive, expensive and require an optimization. Although larve sampling is an extremely expensive procedure, only its' results may be a basis for presribed insecticide spraying of pest population.

Аннотация: iTree size (diameter, height, crown length) distributions in young pine forests of the natural origin (of the second- age class) developing in Central Siberia have been taken into consideration. Nineteen stands representing a series of density variants varied from 1826 to 33381 trees ha. With use of curve-fitting distribution by Pearson the analysis of density affecting stands structure was carried out. The denser stands are found to be thinner, shorter, with undeveloped crown and ,in general, more homogencous. Diameter of the stand is more sensitive to density increase than tree height and crown length.
