Аннотация: The content and composition of alcohol soluble phenolic acids (PhAs) were studied during cell xylem growth in course of wood annual increment formation in the trunks of Scots pine. Cells of the cambium zone, two stages of expansion growth, and outset of secondary thickening zone (before lignification) within the period of formation of early wood xylem were subsequently isolated from trunk segments of 25-year-old trees with constant anatomical and histochemical control. The amount of free and bound forms of phenolic acids extracted from tissues by 80% ethanol, as well as their ethers and esters, were calculated both per dry weight and per cells. The substantial alteration in content, proportion of fractions and composition of acids has been found between the cambium zone and the outset of secondary thickening of tracheids, and the character of variation depended on the calculation method. The amount of free and bound PhAs and esters and especially ethers calculated per cell had increased at the first stage of extension growth, reduced at the second, and increased in the outset of secondary wall deposition. The pool of bound acids was more than acids by 2-5 times depending on the stage of development of the cells. Sinapic and ferulic acids dominate among free hydroxycinnamic acids. The composition and the content of hydroxycinnamic acids in esters and ethers also depended on the stage of development of the cells. p-Coumaric and sinapic acids were the main aglycons in ethers in the cambium and sinapic and caffeic acids were in the other stages. The esters from cambium included mostly p-coumaric acid and those at other stages of development were sinapic and ferulic acids. The esters included benzoic acid at the first stages of growth. The pool of these esters decreased from the first phase of growth until the outset of cell wall thickening. The level of free benzoic acid increased respectively.

Аннотация: Results of measurements and calculations of carbon budget parameters of forests and swamps of Siberia are reported. The zonal variability of reserves (and an increment in reserves) of carbon in forest and swamp ecosystems is characterized, carbon dioxide fluxes are measured directly by means of microeddy pulsations, and an uncertainty brought into the calculation of carbon budget parameters by forest fires is estimated.

Аннотация: Feasibility was tested of estimating the total stem volume and aboveground biomass from data of only the largest trees in even-aged pure stands. We applied a method of fitting a size-distribution function to data that exclude information of smaller individuals in a stand and compared the predicted stem volume and aboveground biomass with those calculated with data of all living trees in the stand. The paired t test showed that the predicted values of the total stem volume and aboveground biomass were not different (p = 0.05) from those observed even if only the largest 10% of the trees were used for estimation with the -3/2 power distribution. Results were similar with the beta-type distribution; however, data from at least the largest 30% of the trees in the stand must be included. Absolute values of the relative error of the predicted total stem volume or aboveground biomass were generally in the range 10-20%, indicating that the present method is accurate enough to be used for calculation of these variables. However, there is systematic bias in the predictions of the total stem volume and aboveground biomass of a stand. Possible causes of the indicated biases and potential ways for improvement of the predictions were discussed.

Аннотация: Based on review and original data, this synthesis investigates carbon pools and fluxes of Siberian and European forests (600 and 300 million ha, respectively). We examine the productivity of ecosystems, expressed as positive rate when the amount of carbon in the ecosystem increases, while (following micrometeorological convention) downward fluxes from the atmosphere to the vegetation (NEE=Net Ecosystem Exchange) are expressed as negative numbers. Productivity parameters are Net Primary Productivity (NPP=whole plant growth), Net Ecosystem Productivity (NEP = CO2 assimilation minus ecosystem respiration), and Net Biome Productivity (NBP=NEP minus carbon losses through disturbances bypassing respiration, e.g. by fire and logging). Based on chronosequence studies and national forestry statistics we estimate a low average NPP for boreal forests in Siberia: 123 gC m(-2) y(-1). This contrasts with a similar calculation for Europe which suggests a much higher average NPP of 460 gC m(-2) y(-1) for the forests there. Despite a smaller area, European forests have a higher total NPP than Siberia (1.2-1.6 vs. 0.6-0.9 x 10(15) gC region(-1) y(-1)). This arises as a consequence of differences in growing season length, climate and nutrition. For a chronosequence of Pinus sylvestris stands studied in central Siberia during summer, NEE was most negative in a 67-y old stand regenerating after fire (-192 mmol m(-2) d(-1)) which is close to NEE in a cultivated forest of Germany (-210 mmol m(-2) d(-1)). Considerable net ecosystem CO2-uptake was also measured in Siberia in 200- and 215-y old stands (NEE:174 and - 63 mmol m(-2) d(-1)) while NEP of 7- and 13-y old logging areas were close to the ecosystem compensation point. Two Siberian bogs and a bog in European Russia were also significant carbon sinks (-102 to - 104 mmol m(-2) d(-1)). Integrated over a growing season (June to September) we measured a total growing season NEE of -14 mol m(-2) summer(-1) (-168 gC m(-2) summer(-1)) in a 200-y Siberian pine stand and -5 mol m(-2) summer(-1) (-60 gC m(-2) summer(-1)) in Siberian and European Russian bogs. By contrast, over the same period, a spruce forest in European Russia was a carbon source to the atmosphere of (NEE: + 7 mol m(-2) summer(-1) = + 84 gC m(-2) summer(-1)). Two years after a windthrow in European Russia, with all trees being uplifted and few successional species, lost 16 mol C m(-2) to the atmosphere over a 3-month in summer, compared to the cumulative NEE over a growing season in a German forest of -15.5 mol m(-2) summer(-1) (-186 gC m(-2) summer(-1); European flux network annual averaged - 205 gC m(-2) y(-1)). Differences in CO2-exchange rates coincided with differences in the Bowen ratio, with logging areas partitioning most incoming radiation into sensible heat whereas bogs partitioned most into evaporation (latent heat). Effects of these different surface energy exchanges on local climate (convective storms and fires) and comparisons with the Canadian BOREAS experiment are discussed. Following a classification of disturbances and their effects on ecosystem carbon balances, fire and logging are discussed as the main processes causing carbon losses that bypass heterotrophic respiration in Siberia. Following two approaches, NBP was estimated to be only about 13-16 mmol m(-2) y(-1) for Siberia. It may reach 67 mmol m(-2) y(-1) in North America, and about 140-400 mmol m(-2) y(-1) in Scandinavia. We conclude that fire speeds up the carbon cycle, but that it results also in long-term carbon sequestration by charcoal formation. For at least 14 years after logging, regrowth forests remain net sources of CO2 to the atmosphere. This has important implications regarding the effects of Siberian forest management on atmospheric concentrations. For many years after logging has taken place, regrowth forests remain weaker sinks for atmospheric CO2 than are nearby old-growth forests.

Аннотация: A global vegetation model based on the climatological approach of Budyko is developed. The major vegetation zones of the world are predicted by a two-dimensional ordination of a Dryness Index and Potential Evaporation, which is derived from radiation balance. Mean temperature of the warmest month is also used to separate the Ice/Polar Desert, Tundra, and Taiga zones. Predictions of vegetation distributions are made using a global climate database interpolated to a 0.50 by 0.50 terrestrial grid. The overall impression from examining the resulting global vegetation map is that the modified Budyko model predicts the location and distribution of the world's vegetation fairly well. Comparison between model predictions and Olson's actual vegetation map were based on Kappa statistics and indicate good agreement for Ice/Polar Desert, Tundra, Taiga, and Desert (even though we predict too much Desert). Agreement with Olson's map was fair for predicting the specific location of Tropical Rain Forest and Tropical Savannas, and was good for predicting their general location at a larger scale. Agreement between Olson's map and model predictions were poor for Steppe, Temperate Forest, Tropical Seasonal Forest, and Xerophytic Shrubs, although the predictions for Temperate Forest and Tropical Seasonal Forest improved to fair at a larger scale for judging agreement. Agreement with the baseline map of Olson was poor for Steppe and Xerophytic Shrubs at all scales of comparison. Based on Kappa statistics, overall agreement between model predictions and Olson's map is between fair and good, depending on the scale of comparison. The model performed well in comparison to other global vegetation models. Apparently the calculation of radiation balance and the resulting Dryness Index and Potential Evaporation provides important information for predicting the distribution of the major vegetation zones of the world.

Аннотация: Reconstruction of climate change in Central Asia over the last millennium with an annual resolution was made using geochemical and biological proxy in lake bottom sediments and tree-ring data. We investigated the lake in Central Asia- Teletskoe (Altai), Kucherla (Altai), Baikal, Arahlei (Chita) - and adjacent areas. Cores of bottom sediments were investigated by method of scanning X-ray fluorescent analysis with synchrotron radiation with the spatial resolution of 0.1 mm. It corresponds to the time resolution ~ 0.2-0.5 year. At each point analyzed more than 30 trace elements from K to U. Geochemical proxy of terrigenous, organogenous and aerosol components of sediments well correlated with regional meteodata for the last 100-150 years. Time series of lithological-geochemical indicators of climate change based on dating by 14C, 137Cs and 210Pb was calibrated by instrumental hydrometeorological data. We used tree-ring series together with element contents as an additional proxy for calculation of transfer function, considering that tree-ring series are response to summer temperature in this climatic zone. Annual temperature and precipitation change for the Central Asia region (0 - 1000 years ago) have been reconstructed using the transfer functions such as: time series proxy=function (temperature, precipitation).

Аннотация: Forest areas can intercept surface runoff from upslope bare areas and transfer it to interflow. Therefore, planting protective forests along the banks of rivers, reservoirs, and lakes preserves natural water sources from pollution. Depending on the particular landscape conditions, the streamside forest shelterbelt (SFS) width is often either wider or narrower than the ecologically substantiated width. As a result, either water quality worsens or the ecologically unjustified prohibition of forest use leads to economic losses. The assessment of SFS width using GIS technologies allows considerable simplification of evaluation procedures and their application in practice. DEM processing is integrated into most modern GIS software packages. For example, the popular ESRI ArcGIS package with its Spatial Analyst module provides extra options for calculating a series of relief-based hydrological features, which include calculation procedures for surface flow direction, length of flow-producing slopes and surface flow accumulations. Two algorithms for GIS-based SFS construction were tested for several rivers of the Yenisei basin and Krasnoyarsk Reservoir, Siberia. The first algorithm is technically simple and based on empirical equations of runoff slope length, slope steepness and soil infiltration. The second one includes a three-dimensional flow accumulation procedure and thus it is more sensitive to real surface structure. Both algorithms are ready to be used in practice. The results obtained indicate that, on average, the SFS width along banks of large rivers might be reduced, while in some cases it should be widened along the banks of small streams.

Аннотация: Radial growth climatic response of trees growing in middle elevation zone (1000-1700 m) of Altai-Sayany mountainous country was analyzed. Tree-ring sites are mainly located in mountain hollows and slopes of bounding ridges and can be described as mountain forest-steppe ecotones, where the growing conditions are characterized by low moisture. Radial growth of trees from these conditions was compared to tree growth patterns at the upper timberline and in forest-steppe zone. Analysis of extreme growth values and calculation of moving correlation coefficients have shown that tree-growth climatic response in mountain forest-steppe ecotones is mixed and unstable in time. Tree growth is dominated by two major factors - moisture supply and air temperature. At the same time temperature can influence tree-growth negatively as well as positively. Instability of the climatic response consists in that sing and percent of air temperature contribution to growth value changes in time. It was also revealed that the cause of climatic response instability is air temperature dynamics, i.e. alternate cooling and warming. В© 2006 V. N. Magda, E. A. Vaganov.

Аннотация: The formation of phloem was studied for two years in stems of 50 to 60 year old trees of Scots pine (Pinus sylvestris L.) growing in nature. The development of phloem of the current year begins 10 to 20 days before the xylem formation and is completed with the termination of shoot growth in the end of June. Observations over the seasonal activity of cambium producing sieve cells of phloem and duration of their differentiation as compared to the xylem derivatives of cambium have shown that the maxima of formation of phloem and xylem cells could coincide or not coincide by season, while the activities of their differentiation were always in antiphase. The sieve cells of early phloem were separated from those of late phloem by a layer of tannin-containing cells, which are formed simultaneously with the formation of late xylem cells by the cambium. Seasonal dynamics of accumulation of starch grain in structural elements of the phloem is related to the xylem development. The content of metabolites in differentiating and mature phloem elements, in the cambium zone, and in the xylem cells growing in the radial direction depended on cell specificity, stage of their development, and type of forming wood, early or late, which differ in the cell wall parameters and, hence, requirement of assimilates. Significant differences were described between the content of low molecular weigh carbohydrates, amino acids, organic acids, and phenol compounds using two methods of calculation: per dry weight and per cell.

Аннотация: NASA's ICESat Geoscience Laser Altimeter System (GLAS) was launched in January 2003 and collected lidar data during February and September of that year. Lidar is a laser altimeter that measures the distance from the instrument to the surface by measuring the time elapsed between the pulse emission and the reflected return. The returned signal may identify multiple returns originating from trees, buildings and other objects and permits the calculation of their height. Sampling the returns at discrete time intervals enables backscatter profiles to be constructed. Lidar data can provide estimates of other structural parameters such as biomass, stand volume and leaf area. This study used GLAS data acquired over our study sites in central Siberia to examine the signal as a source of information of forest stand characteristics. Example lidar profiles are presented and preliminary analysis is described. The results indicate that GLAS profile information may be useful for understanding MODIS landcover classes.

Аннотация: Wood material from living trees and trunk remains of Siberian larch (Larix sibirica Ldb) from the upper treeline (2300 m) of the Mongun Taiga mountain massif was used for building up a 2367-year Mongun tree-ring chronology. The chronology is consistent with paleoclimatic data and reflects the main changes in the climate of the Northern Hemisphere over the last two millennia: the cooling of the 6th century, "Medieval warming," "Little Ice Age," and the current warming. The calculation of the response function between the chronology and data from weather stations made it possible to reconstruct the variability of air temperatures in June and July for 2000 years. The chronology contains the climate signal of regional scale and is suitable for dating archaeological wood, that is, for determining the calendar time of building the monuments in the Altai-Sayan region.

Аннотация: The authors propose several methods of net primary production (NPP) evaluation for tree stands of Middle Siberia. The authors’ approach is based on the model of the distribution of tree (tree stand) phytomass among different tree components (stem, roots, branches, foliage) using the Zipf-Pareto equation. This model can be used not only to calculate the phytomass and NPP of the tree aboveground parts but also to determine quite accurately the phytomass and NPP of the roots. Several approaches to calculation of tree stand NPP have been proposed, depending on the amount of available data. © Springer International Publishing Switzerland 2015.

Аннотация: We analyzed variability of taxation indicators of trees and stands in stows and forest planning units. We compared consistency of stands across several stows in montane taiga and several forest planning units. We found lower variability of taxation indicators across units recognized on natural (morphological) basis. This could be applied to raise the accuracy of taxation and workforce productivity of taxators. Since the stand and the forest terms are incomplete and ambiguous in professional literature, we made an attempt to do it. Based on robust material of taxation for every tree at sample plots, including height and trunk diameter, length and the crown cross section we studied the variability across two ontogenetic sequences of forest stands of similar type. The first was in dense pine forests of 30–280 years old, and the second was in the stands of 30–110 years old and medium density. This helped to find the necessary number of measurements for trees at various accuracy levels, depending on the stand age. This could be applied in studies of bioproductivity of forest. Moreover, it allows finding minimal size of a sample plot depending on the age to avoid errors in calculation of trunk storages and phytomass of a crown. All normative indicators were compiled in the tables. Based on available literature and personal data, we provide numerical indicators for prism-count plots for forest taxation, applicable in compiling forest inventories. © 2018, Izdatel'stvo Nauka.

Аннотация: The correlation between the kinetic stability of molecules against temperature and variations in their geometric structure under optical excitation is investigated by the example of different organic pheromone molecules sensitive to temperature or ultraviolet radiation using the density functional theory. The kinetic stability is determined by the previously developed method based on the calculation of the probability of extension of any structural bond by a value exceeding the limit value Lмах corresponding to the breaking of the bond under temperature excitation. The kinetic stability calculation only requires the eigenfrequencies and vibrational mode vectors in the molecule ground state to be calculated, without determining the transition states. The weakest bonds in molecules determined by the kinetic stability method are compared with the bond length variations in molecules in the excited state upon absorption of light by a molecule. Good agreement between the results obtained is demonstrated and the difference between them is discussed. The universality of formulations within both approaches used to estimate the stability of different pheromone molecules containing strained cycles and conjugated, double, and single bonds allows these approaches to be applied for studying other molecules.

Аннотация: Response to anthropogenic disturbances, recorded according to remote sensing of the Earth, has a long-term manifestation not only in the spectral characteristics of the channels of visible and near infrared ranges of satellite imagery, but also in the study of the temperature field. The paper deals with the local excess temperature of the underlying surface in the areas of cutting the territory of the Angara region, compared with the background values identified by satellite data Landsat 5 and 8 for the seventeen-year period. Estimates of the relative difference in the temperature of the underlying surface of the cutting area in comparison with the average background values are obtained. To this end, a number of software products to automate the archiving and conversion of satellite information has been developed. These software products are designed for calculation of the radio-brightness temperature of the underlying surface of disturbed and undisturbed areas of forest vegetation in the pre-selected areas of the territory. They are also used to average the obtained data of radio-brightness temperature and to calculate the difference between the average values of the radio-brightness temperature of the underlying surface of the disturbed areas relative to the undisturbed, that is, the background. This approach can significantly reduce the processing time of a large amount of information and optimize the amount of data storage. Separately, the study area was analyzed according to the NDVI vegetation index. The data obtained demonstrate a high rate of recovery of grass cover and grass-shrub layer immediately after damage to forest vegetation. It is shown that during the considered period of time (17 years) the value of excess temperature decreases, which is determined by the processes of vegetation restoration, including stand on felling. It is established that the increased temperatures of the underlying surface in the place of cuttings are remained for at least 15 years, and the temperature increase over the background values in the conditions of the observed successional processes is not less than 10%. As a limiting factor in the restoration of the temperature background of the underlying surface, fires can act. © SGEM2019. All Rights Reserved.

Аннотация: Abstract: The DNA polymorphism of seven coenopopulations of Siberian stone pine (Pinus sibirica Du Tour) growing in a region which is typical for mountain taiga pine forests—the northeastern part of the Kuznetsk Alatau—has been studied. According to the data of 11 nuclear microsatellite loci, 44 allelic variants which significantly differed between the studied coenopopulations in composition and frequency of occurrence are identified. The highest level of allelic diversity is found in the Ps_80612 and Ps_1502048 loci, in which eight and seven alleles are detected, respectively. The calculation of the main parameters of genetic diversity have shown, on the whole, a relatively low level of polymorphism of the studied samples (NA = 3.078, NE = 1.877, HE = 0.445, and HO = 0.401). An analysis of the degree of subdivision of coenopopulations has revealed that about 95% of the total genetic diversity is concentrated within populations, while the interpopulation component accounts for only about 5% (FST = 0.049). The diagnosed differences in the level of P. sibirica genetic polymorphism are determined by several factors: the presence of orographic and phytocenotic barriers between the coenopopulations, which define the directions of seed propagation vectors along the watercourses of river basins that form the Chulym River in the eastern sector of the Kuznetsk Alatau and Tom River in the western sector; a significant level of bioclimatic and environmental extremeness of habitats of coenopopulations in accordance with the height above sea level; and anthropogenic pressure, including periodic deforestation and recreational impact on coenopopulations located near settlements. These factors, which have a significant microevolutionary component, determine the adaptation trends of coenopopulations of P. sibirica and morphological singularities and reproductive potential of trees and, ultimately, they control their genetic polymorphism in the studied part of the Kuznetsk Alatau. © 2020, Pleiades Publishing, Ltd.

Аннотация: Исследован полиморфизм ДНК семи ценопопуляций сосны сибирской кедровой (Pinus sibirica Du Tour), произрастающих в характерном для горно-таежных кедровников регионе - северо-восточной части Кузнецкого Алатау. По 11 ядерным микросателлитным локусам выявлено 44 аллельных варианта, существенно отличающихся у изученных ценопопуляций по составу и частотам встречаемости. Самый высокий уровень аллельного разнообразия имеют локусы Ps _80612, Ps _1502048, в которых выявлено 8 и 7 аллелей соответственно. Расчет основных параметров генетического разнообразия показал в целом сравнительно невысокий уровень полиморфизма исследованных выборок ( NA = 3,078; NE = 1,877; HE = 0,445; HO = 0,401). Анализ степени подразделенности ценопопуляций выявил, что внутри популяций сосредоточено около 95 % всего генетического разнообразия, тогда как на межпопуляционную составляющую приходится всего около 5 % (F ST = 0,049). Диагностированные различия в уровне генетического полиморфизма P. sibirica определяются: наличием между ценопопуляциями орографических и фитоценотических барьеров, обусловливающих направления векторов распространения семян вдоль водотоков бассейнов рек, формирующих р. Чулым в восточном секторе Кузнецкого Алатау и р. Томь - в западном; значительным уровнем биоклиматической и экологической экстремальности местопроизрастаний ценопопуляций в соответствии с высотой над уровнем моря; антропогенной нагрузкой, включающей периодические рубки и рекреационное воздействие на расположенные вблизи населенных пунктов ценопопуляции. Данные факторы, имеющие выраженную микроэволюционную составляющую, детерминируют адаптивные тренды ценопопуляций P. sibirica, морфологическое своеобразие и репродуктивный потенциал деревьев и, в конечном счете, контролируют их генетический полиморфизм в исследованной части Кузнецкого Алатау.
The DNA polymorphism of 7 coenopopulations of Siberian stone pine ( Pinus sibirica Du Tour), growing in the region which is typical for mountain taiga pine forests - the north-eastern part of the Kuznetsk Alatau, was studied. According to the data of 11 nuclear microsatellite loci, 44 allelic variants, which significantly differed between the studied cenopopulations in composition and frequency of occurrence were identified. The highest level of allelic diversity is found in the Ps_80612, Ps_1502048 loci, in which 8 and 7 alleles were detected, respectively.
