Аннотация: Estimates of carbon (C) storage for the forest vegetation of Russia vary to a considerable extent. In this paper we describe methods of estimating C storage of forest ecosystems and present estimates of C storage in the forest vegetationb of administrative territories and ecoregion of Russia. Estimates of C storage are based on National Forest Inventory data, estimates of the phytomass of trees and other vegetation of different forest ecosystems in various ecoregions of Russia, and mapped data for natural ecoregions. The forest ecosystems of Russia (771.1 Mha) have 118.8 Pg of C with 23.6% of the total in forest vegetation, 14.1% in the countries with temperate and boreal forest ecosystems.

Аннотация: Estimating terrestrial ecosystem CO2 fluxes is very important for our understanding of the global carbon cycle. This paper presents a zero-dimensional mathematical model of the ecosystem of Siberian boreal forests. It was used for comparison tall-tower-based CO2 fluxes with biometric field measurements. The model is a system of ordinary differential equations with additional conditions superimposed on the parameters. The main occurring proceses.are described - photosynthesis, respiration, seasonal changes of active phytomass, water balance of trees, the influence of light, humidity, and temperature of phytosynthesis and respiration.

Аннотация: A change in the mass and composition of organic matter in the phytomass and soil of pine forests affected by mid-intensity and high-intensity fires is considered. It is shown that a mid-intensity fire did not catastrophically affect the pool of carbon in the middle-aged pine forests of the subtaiga forest-steppe and the taiga higher belt areas in the southwest of the Baikal region. Five years after a high-intensity fire, the carbon reserves in a mature taiga pine forest remain 20% lower than in an unaffected pine forest. Compared with the reference figures, the mass of C and soil cover in the stand phytomass decreased by 18 and 63%, respectively. In the easily mineralizable fraction of organic matter, the reserves of carbon decreased by half owing to burnout of waste wood (by 64%) and root detritus (by 50% compared with the reference tree stand figures).

Аннотация: Forest harvesting is a major human-caused disturbance affecting carbon budgets in forest ecosystems. This study was concerned with post-logging carbon pool changes in Scots pine (Pinus sylvestris) and Siberian fir (Abies sibirica) stands. To understand carbon budget recovery trends following logging, carbon stock and fluxes were measured in stands differing in time since logging. In both Scots pine and fir stands disturbed by logging, the tree phytomass contribution to the carbon budget decreased drastically, whereas the coarse woody debris (CWD) carbon pool exhibited a marked increase. Sixty years following logging, the Scots pine stand carbon storage was almost 70 % of that prior to logging and the ratio between the phytomass and soil organic matter was the same as before the disturbance. While the phytomass carbon showed a similar trend in the fir stand of the same age, it was less than on the control stand. In a 50-55-year-old fir stand, 26 years since harvesting, the phytomass carbon recovered only by 15 %. Siberian fir and Scots pine logging sites differed in CWD loading and decomposition rate. The phytomass dynamics and CWD loading values obtained suggest that Scots pine stands which have experienced logging are most likely carbon sinks, as was clear from the phytomass production exceeding organic matter decomposition-caused fluxes. Conversely, logged fir ecosystems are likely to be sources of carbon to the atmosphere due to a large CWD loading, faster rate of its decomposition, and slow phytomass increment.

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: The dynamics of organic matter accumulated in the soil and main vegetation elements was analyzed for post-logging forest ecosystem succession series in eastern Baikal region. The phytomass was found to allocate up 63 and 50% of carbon in undisturbed Scots pine and fir stands, respectively. The post-logging phytomass contribution to the total carbon pool appeared to decrease down to 16% in Scots pine and 6% in fir stands. In Scots pine stands, carbon storage was determined to account for almost 70% of the initial carbon 60 years after logging. In 50- to 55-year-old fir stands, carbon recovered its initial pool only by 10%. Soil carbon recorded in recently logged Scots pine and fir sites appeared to be 5 and 16 times that accumulated in the phytomass, respectively. The ratio between phytomass carbon and soil organic matter recovered back to the prelogging level in Scots pine stands by the age of 50-60 years. While phytomass carbon also increased in fir stand of the same age, it did not reach the level of the control stand.

Аннотация: Phenomenological models of the forest plantations growth are analyzed. Those derived from the Verhulst's model are shown to fail describing qualitative effects reflecting tree growth, phytomass withdrawals, and plantation restoration. The method of phase portraits is used for exploration of the forest ecosystem dynamics, which allows to describe regulatory mechanisms of the growth processes, regulation delay, and feedback types. A bistable phenomenological model is suggested herewith to characterize dynamic processes in the forest ecosystems. Principal patterns of formation of the forest plantations at different stages of the forest generation processes are considered on the basis of that model, and ecological effects responsible for the plantation dynamics are revealed.

Аннотация: Steppe ecosystems represent an interesting case in which the assessment of carbon balance may be performed through a cross validation of the eddy covariance measurements against ecological inventory estimates of carbon exchanges (Ehman et al., 2002; Curtis et al., 2002). Indeed, the widespread presence of ideal conditions for the applicability of the eddy covariance technique, as vast and homogeneous grass vegetation cover over flat terrains (Baldocchi, 2003), make steppes a suitable ground to ensure a constrain to flux estimates with independent methodological approaches. We report about the analysis of the carbon cycle of a true steppe ecosystem in southern Siberia during the growing season of 2004 in the framework of the TCOS-Siberia project activities performed by continuous monitoring of CO2 fluxes at ecosystem scale by the eddy covariance method, fortnightly samplings of phytomass, and ingrowth cores extractions for NPP assessment, and weekly measurements of heterotrophic component of soil CO2 effluxes obtained by an experiment of root exclusion. The carbon balance of the monitored natural steppe was, according to micrometeorological measurements, a sink of carbon of 151.7 +/- 36.9 g Cm-2, cumulated during the growing season from May to September. This result was in agreement with the independent estimate through ecological inventory which yielded a sink of 150.1 g Cm-2 although this method was characterized by a large uncertainty (+/- 130%) considering the 95% confidence interval of the estimate. Uncertainties in belowground process estimates account for a large part of the error. Thus, in particular efforts to better quantify the dynamics of root biomass (growth and turnover) have to be undertaken in order to reduce the uncertainties in the assessment of NPP. This assessment should be preferably based on the application of multiple methods, each one characterized by its own merits and flaws.

Аннотация: The Sayano-Shushensky Nature Reserve is a standard primeval locus of high conservation value which remained undisturbed landscapes within the Altai-Sayan Mountain Land. In the plant cover the altitudinal belts are clearly expressed. The northern part of the Sayan-Shushensky reserve is included in moist areas of the Altai-Sayan forest vegetation zone and the Southern part of it is included in insufficiently moist areas of Central Asian forest zone. The ground vegetation of the reserve is presented by high-mountain tundra, meadows and shrub thicket sites, high-mountain open Pinus sibirica D u. T o u r. and Larix sibirica L e d e b. woodland, dark and light coniferous taiga, coniferous subtaiga, forest-steppe and steppe. As a whole forests occupy somewhat about 60% of the territory. Ecocenotic groups of species found in individual phytocoenoses in river basins of the northern part of the nature reserve are qualitatively different in composition and share from those ones found in the southern river basins. In the north, the high mountain ecocenotic species group enjoys the greatest abundance, and forest-meadow, taiga, and bog species are also represented substantially. Steppe and forest-steppe species are absent. Alpine, steppe, and forest-steppe species are found in equal shares in the southern part of the forest reserve. Invasive species are quite many. Taiga species contribution is three times less than in the north of the reserve. Conditions climatically optimal for the greatest species diversity are the result of a perfect balance of heat and moisture characteristics of subtaiga/forest-steppe altitudinal belt complexes (ABC). However, changes in phytochorological- and alpha-diversity of individual phyl.ocoenoses are influenced by ecological and phytocoenotic factors combined. The biggest number of species in the reserve occurs along the forest distribution boundaries - in subtaiga and high mountain open woodland whereas species are the fewest in mountain taiga. Conversely, phytomass loading is the greatest in mountain taiga and it decreases gradually towards alpine tundra and steppes.

Аннотация: The changes of arboreous coenoses composition resulting from natural and anthropogenic impacts are considered. The mathematical model is proposed and verified that describes arboreous cenoses transition from one succession state into another by analogy with phase transition in statistical physics. It is demonstrated that the model is concordant with the data of full-scale observations. The model allows to explain the trend of succession processes and determine the stage of forestation process at which succession transitions should be expected. The analysis of full-scale observations data by means of the proposed approach makes it possible to calculate, for given regions and forest types, the critical values of planting phytomass that, upon being attained, initiate the succession transition. Those values are important to be known for middle- and long-term forecasting of forest cover dynamics.

Аннотация: Processes of xylem formation in Dahurian larch have been studied at three sites differing in the hydrothermal regime of soils in the permafrost zone of Middle Siberia. It has been found that the start and end dates of different phases of tree ring formation may differ between the sites by up to 14 days, depending on site conditions. The data obtained contribute to knowledge of possible changes in larch forest phytomass production and provide the possibility of predicting its dynamics under conditions of climate change.

Аннотация: In the long-term (30 years) field provenance experiment (Novosibirsk, Russia) with Scotch pine Pinus sylvestris L. from different geographical populations, X-ray fluorescence analysis with synchrotron radiation (XRFSRA) was used to estimate the concentration of 16 chemical elements in different components of the phytomass collected from living trees and the soil under them. The statistically significant influence of the "geographical population" factor on the elemental composition of different components of phytomass and soil was shown. A relationship between chemical properties and morphometric traits was found.

Аннотация: Local-level, bioclimatic regression models that relate stand characteristics (forest composition, height, site quality class and wood stocking) to site climate (temperature sums, base 5 degrees C, and dryness index) were developed to predict the stand structure of dark-needled forest (Pinus sibirica and Abies sibirica) climax successions and their transformations in a changing climate over the Sayan mountain range in southern Siberia. The models explained up to 80% of the variation in forest growth and productivity characteristics. Productivity varied widely and depended on heat supply rather than moisture. Stand tree species composition depended oil moisture: dark-needled species and light-needled tree species (Pinus sylvestris) were separated by a dryness index value of 1.0. Living phytomass was calculated from a wood stocking model. Tree heights and living phytomass were mapped over the mountain range under current climate conditions and a regional climate change scenario. The model predicts that total dark-needled forest phytomass will decrease by 17% in a warmed climate.

Аннотация: Phytomass (live plant mass) and net primary productivity are major components of the terrestrial carbon balance. A major location for phytomass storage is the subcontinent of Siberia, which is dominated by extensive reaches of taiga (boreal forest). The responsiveness of the phytomass component of the carbon pool is examined by comparing vegetation in the mid-Holocene (4600-6000 years before present) to modern potential vegetation. The mid-Holocene was warmer and moister in middle and northern Siberia than today, producing conditions ideal for boreal forest growth. As a result, both northern and middle taiga were dominated by shade-tolerant dark-needled species that thrive in moist climates. Today, shade-tolerant dark-needled taiga is restricted to western Siberia and the highlands of central Siberia, with its central and eastern components in the mid-Holocene replaced today by light-demanding light-needled species with lower productivity and phytomass. Total phytomass in Siberia in the mid-Holocene was 105.0 +/- 3.1 Pg, compared to 85.9 +/- 3.2 Pg in modern times, a loss of 19.1 +/- 3.1 Pg of phytomass. The reduction in dark-needled northern and middle taiga classes results in a loss of 28.8 Pg, while the expansion of the corresponding light-needled taiga results in a gain of 13.5 Pg, a net loss of 15.3 Pg. The loss is actually greater, because the modern figures are for potential vegetation and not adjusted for agriculture and other anthropogenic disturbances. Given long periods for vegetation to approach equilibrium with climate, the phytomass component of the carbon pool is responsive to climate change. Changes in net primary productivity (NPP) for Siberia between the mid-Holocene and the present were not as large as changes in phytomass. A minor decrease in NPP (0.6 Pg yr(-1), 10%) has occurred under our cooler modern climate, primarily due to the shift from dark-needled taiga in the mid-Holocene to light-needled taiga today.

Аннотация: The resource-ecological potential of forests is represented by the reserves of growing stock and total phytomass. Non-exhaustion forest exploitation can be based on a balance of deafforestation and appropriate regeneration of timber and other forest resources, and efficient protection against fires and other negative impacts for a stable development of the forest complex and for sustained resource and ecological functions of forests.

Аннотация: Methods for assessing the primary productivity of the forest stands between various tree species in different environmental conditions are considered. Methods for the primary productivity assessment using data on the phytomass fractions and stand wood stock have been proposed. It is shown that the Zipf-Pareto equation of the relationship between the phytomass of some tree fractions in the stand can be used for a primary productivity estimation of the stock volume. A model analogous to R. Solow's macroeconomic model has been proposed to describe the processes of the phytomass growth in the forest stand.
