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
Remote sensing of photosynthetic-light-use efficiency of a Siberian boreal forest
/ C. J. Nichol, O. Shibistova // Tellus. Series B: Chemical and physical meteorology. - 2002. - Vol. 54B, № 5. - С. 677-687
Аннотация: The relationship between a physiological index called the photochemical reflectance index (PRI) and photosynthetic light-use-efficiency (LUE) of a Siberian boreal forest during the winter-spring transition, or green-up period, was investigated in 2000. During this time the photosynthetic apparatus was considered under stress as a result of extremes of temperature (from -20 to 35 degreesC) coupled with a high radiation load. Reflectance measurements of four stands were made from a helicopter-mounted spectroradiometer and PRI was calculated from these data. Eddy covariance towers were operating at the four stands and offered a means to calculate LUE. A significant linear relationship was apparent between PRI, calculated from the helicopter spectral data, and LUE, calculated from the eddy covariance data, for the four sites sampled. Reflectance measurements were also made of a Scots pine stand from the eddy covariance tower. Needles were also sampled during the time of spectral data acquisition for xanthophyll pigment determination. Strong linear relationships were observed among PRI, the epoxidation state of the xanthophyll cycle (EPS) and LUE over the green-up period and the diurnal cycle at the canopy scale.

Three years of trace gas observations over the EuroSiberian domain derived from aircraft sampling - a concerted action
/ I. Levin, N. M. Tchebakova, O. Shibistova // Tellus. Series B: Chemical and physical meteorology. - 2002. - Vol. 54B, № 5. - С. 696-712
Аннотация: A three-year trace gas climatology of CO2 and its stable isotopic ratios, as well as CH4, N2O and SF6, derived from regular vertical aircraft sampling over the Eurasian continent is presented. The four sampling sites range from about 1degreesE to 89degreesE in the latitude belt from 48N to 62degreesN. The most prominent features of the CO2 observations are an increase of the seasonal cycle amplitudes of CO2 and delta(13)C-CO2 in the free troposphere (at 3000 m a.s.l.) by more than 60% from Western Europe to Western and Central Siberia. delta(18)O-CO2 shows an even larger increase of the seasonal cycle amplitude by a factor of two from Western Europe towards the Ural mountains, which decreases again towards the most eastern site, Zotino. These data reflect a strong influence of carbon exchange fluxes with the continental biosphere. In particular, during autumn and winter delta(18)O-CO2 shows a decrease by more than 0.5parts per thousand from Orleans (Western Europe) to Syktyvkar (Ural mountains) and Zotino (West Siberia), mainly caused by soil respiration fluxes depleted in delta(18)O with respect to atmospheric CO2. CH4 mixing ratios in the free troposphere at 3000 m over Western Siberia are higher by about 20-30 ppb if compared to Western Europe. Wetland emissions seem to be particularly visible in July-September, with largest signals at Zotino in 1998. Annual mean CH4 mixing ratios decrease slightly from 1998 to 1999 at all Russian sites. In contrast to CO2 and CH4, which show significant vertical gradients between 2000 and 3000 m a.s.l., N2O mixing ratios are vertically very homogeneous and show no significant logitudinal gradient between the Ural mountains and Western Siberia, indicating insignificant emissions of this trace gas from boreal forest ecosystems in Western Siberia. The growth rate of N2O (1.2-1.3 ppb yr(-1)) and the seasonal amplitude (0:5-1.1 ppb) are similar at both aircraft sites, Syktyvkar and Zotino. For SF6 an annual increase of 5% is observed, together with a small seasonal cycle which is in phase with the N2O cycle, indicating that the seasonality of both trace gases are most probably caused by atmospheric transport processes with a possible contribution from stratosphere-troposphere exchange.

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 contribution of black carbon to the carbon storage in a permafrost ecosystem
: материалы временных коллективов / G.

Аннотация: The results of this study thus provides evidence that the BC stocks are strongly related to the OC stocks in general and to the environmental variables that control the OC stocks. A similar result was obtained by Glaser and Amelung for BC in North American native grassland soils. They concluded that the BC storage in soils is controlled by higher BC productiion at sites with high plant biomass and by shorter BC residence time in soils showing favourable conditions for OC decomposition. The data also show that if permafrost degradation is taking place by some kind of disturbance, in particular the bogs will loose BC to a large extent. It is proportionally even more pronounced than for OC in general. Hence, BC in permafrost soils is highly susceptible to permafrost thawing and cannot be considered as a refractory carbon species in such ecosystem. Also it is discussed another questions.

Soil nitrogen dynamics in a larch forest, Central Siberia : A short review of preliminary results
: материалы временных коллективов / S.

Аннотация: Surface soils (organic layer and 0-10 cm mineral soil) from larch forests, Central Siberia, had small pool size of soil inorganic N, while higher values can be observed especially in organic layer in N fertilized sites. Annual leachate of inorganic N was also small before N fertilization, while greater values were observed beneath organic layer in high N site after fertilization. Thus, N treatment seems to stimulate inorganic N dynamics of soil surface, and it may consequently lead to stimulation of lower soils. Dissolved organic nitrogen (DON) was the most important N form constantly supplying dissolved N to soil circumstances in this site, suggesting a possibility of organic N to control on ecosystem processes in these forests.

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.

The structure and biodiversity after fire disturbance
: материалы временных коллективов / O. A. Zyryanova, V. I. Zyryanov et al // Eurasian Journal of Forest Research. - 2007. - Vol. 10-1. - С. 19-29. - Библиогр. в конце ст.
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.

: материалы временных коллективов / A. Ya. Larionova, A. K. Ekart, A. N. Kravchenko // Eurasian Journal of Forest Research. - 2007. - Vol. 10-2. - С. 185-192. - Библиогр. в конце ст.
Аннотация: The genetic diversity and population structure of Siberian fir (Abies sibirica LEDEB.) in Middle Siberia were studied on the basis of allozyme variation analysis at 20 loci. The vegetatives buds collected from 260 trees in nine populations representing different geographical localities and altitudinal sites were used as materials for study. Horizsontal starch gel electrophoresis was applied to analyze the isozyme patterns of 11 enzyme systems. 20% of the gene loci assayed were revealed to be polymorphic at 95%, and 35% at a 99% criterion. The mean number of alleles per locus, the mean observed heterozygosity, the mean expected heterozygosity, and the effective number of alleles were equal. The obtained data indicates a low level of genetic diversity and a weak differentiation among the A. sibirica populations studied in Middle Siberia. The most significant difference in structure was that between Kozulka and Western Sayan.

Перевод заглавия: Succession-driven transformation of plant and soil cover on solifluction sites in the permafrost zone of central Evenkia
Аннотация: Приведены данные о степени повреждения солифлюкциями растительного и почвенного покрова и их регенерации в криолитозоне Центральной Эвенкии в зависимости от длительности постсолифлюкционного периода. Отмечена роль формирующейся растительности в накоплении биогенных элементов и почвообразовании. Для вновь формирующихся почв на солифлюкционных площадях в криолитозоне Средней Сибири характерна высокая концентрация подвижных соединений фосфора, что является одной из основных их особенностей.

Forest disturbance assessment using satellite data of moderate and low resolution
: материалы временных коллективов / M. A. Korets [и др.] // Environmental change in Siberia: earth observation, field studies and modelling. - Dordrecht et. al. : Springer, 2010. - С. 3-19. - Библиогр. в конце ст.
Аннотация: Envisat-MERIS and SPOT Vegetation satelitte data were tested for estimation of vegetation cover disturbance caused by fire and industrial pollution in central and northern Siberia test sites, respectively. MERIS data were used to assess forest disturbance levels on burned sites in Angara region. Chlorophyll indexes (REP and MTCI) were found to allow identifying up to five forest disturbance levels due to high space-borne sensor resolution and sensitivity to chlorophyll content of vegetation. The current vegetation condition was assessed using MTCI index in the northern (Norilsk) test region. The lowest index values calculated for the most severely disturbed vegetation near Norilsk were found to correlate with sulphur concentrations in larch and spruce needles. Another approach to estimating spatial and temporal trends of vegetation condition used the 1998-2005 SPOT-Vegetation satellite data. The relationships obtained between MTCI, NDVI values, and forest mortality were based upon to map the 1998-2005 forest degradation zone dynamics in the northern test site.

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.

Аннотация: A number of forest studies found that forest stands developing on slopes of technogenic origin in oil gas production sites of Western Siberia are markedly more productive compared to surrounding natural stands and contribute to forested land proportions in forest-bog areas. This is believed to be a positive influence of oil and gas industries on the boreal forest development

Аннотация: 285 tree-ring chronologies were used for tree-ring modeling (biophysical VS-model). All chronologies are located in the Eurasian part of Russia. Due to limitations of the present meteorological network in this territory for use in spatial tree-ring modeling, monthly climatic data were obtained from the high spatial resolution climate dataset (Climatic Research Unit, UEA, Norwich, UK) for ieach site. Average monthly temperature and cumulative precipitation were converted into daily data using a technique created by author. These daily datasets were used by the VS-model.

Особенности радиального прироста лиственницы гмелина на Севере Cредней Сибири в разных условиях произрастания

Аннотация: Results of dendroclimatic analysis for Gmelin's larch stands from three sites located along a short topographic transect in a continuous permafrost zone in the north of Central Siberia are presented. Comparative analysis of tree radial growth rates and year-to-yaer variability, as well as climatic response of master chronologies was carried out in relation to the local habitat conditions. Obtained results indicate that the dynamics and climatic response of radial growth is sufficiently different at the sites located along a short distance. This shows that site conditions (i.e. depth and the rate of permafrost thaw) are of crucial importance for spatial variability of tree growth on permafrost soils even within the neighboring stands.
