Аннотация: Climatic and geographic patterns of the spatial precipitation distribution in Central Siberia are studied on a regional level. Computer models of spatiall precipitation distribution were developed for the Yenisei Mountain Chain, Eastern Sayan, and the South-eastern Trans-Baikal region. Owing to irregular spatial distribution of precipitaion three groups of landscapes were defined: (1) slopes of west, north-west aspect with orographic precipitation; (2) shadow slopes in mountain regions; (3) plain landscapes. Obtained equautions show correlations between the amount of precipitation and altitude, geographical latitude, distance from barrier ridge and other parameters.

Аннотация: The symbiotic fixation of atmospheric nitrogen by leguminous plants in the alpine community of a lichen heath at the Teberda State Biosphere Reserve is well adapted to low soil temperature characteristic for the altitude of 2800 m a.s.l. For the determination of the N fixation by isotopic methods (the method of the natural (15)N abundance and the method of isotopic (15)N dilution), Trifolium polyphyllum was taken as the control plant. This plant was used as it does not form symbiosis with the nitrogen-fixing bacteria in the highlands of the Northern Caucasus Region. The contribution of the N fixation to the N nutrition of different leguminous plant species as determined by the natural (15)N abundance method amounted to 28-73% at delta(15)N(0) = 0aEuro degrees and 46-117% at delta(15)N(0) = -1aEuro degrees; for the determination of the N fixation by the method of the isotopic label's dilution, it was 34-97%. The best correlation of the results obtained by these two isotopic methods was observed for the natural fractionation of the N isotopes in the course of the N fixation in the range of -0.5 to -0.7aEuro degrees. The determination of the nitrogenase activity of the roots by the acetylene method confirmed the absence of N fixation in T. polyphyllum and its different contribution to the N nutrition of different species of leguminous plants.

Аннотация: Making the map of ground vegetation and analysis of its present state have been realized as well as dynamic tendencies in development of forest communities from climatic optimum of the Holocene up to the present time have been revealed. Forests of the reserve are mainly overmatured. Presently the succession of mountain taiga- and grass larch and pine forests by fir stands occurs. As a reason for changing formation composition of the main forest forming tree species of the reserve the global climatic changes of the northern hemisphere are. Floristic abundance of forest communities is characterized by high variability. a-diversity increases from the mountain taiga altitude - vegetation belt to the belt of subtaiga forest-steppe what corresponds to the increase of heat providing gradient. High coefficient of beta-diversity value variation in taiga and grass forest ecotone as well as in old cutting areas of light-coniferous forests shows instability of these phytocoenoses and rather fast succession of coenoelements of light-coniferous formations by the dark-coniferous ones.

Аннотация: Tree response to climate trends is most likely to be observed in the forest-tundra ecotone, where mainly temperature limits tree growth. On-ground observation and multitemporal Landsat data were used in the analysis of forest-tundra ecotone dynamics (from 1976 to 2000) in the Western Sayan Mountains, Siberia. Observations showed an increase in forest stand crown closure, upward tree-line and regeneration shift and the transformation of Siberian pine and fir krummholz into arboreal forms. Closed stands were increasing in the area at a rate of 0.8% year -1 and advancing their upper boundary at an altitudinal rate of 0.6 m year -1; these changes were shown mainly by the transformation of sparse stands into closed stands. The altitudinal rate of regeneration propagation was estimated at 1.2 m year -1. It was also found that these changes correlated positively with temperature trends. The response of tree vegetation to air temperature increase was dependent on topographic relief features (azimuth and slope steepness). В© 2010 Taylor & Francis.

Аннотация: Ongoing climatic changes potentially affect tree-line ecosystems, but in many regions the observed changes are superimposed by human activities. We assessed how the forest-tundra ecotone has changed during the last century in the Putorana Mountains, northern Siberia, an extremely remote and untouched area in Eurasia. A space-for-time approach was used to determine the spatio-temporal dynamics of forest structure and biomass along an altitudinal transect. From the closed larch forest to the upper tree line, the mean age of Larix gmelinii (Rupr.) decreased considerably from 220 to 50 years ago. At the current upper species line, there is a strong and successful germination of larch, with 1500 saplings per hectare, indicating an ongoing filling-in, a densification of a formerly open forest and an upslope shift of the tree-line position (approximately 30 to 50m in altitude during the last century). The forest expansion coincided with large increases in winter precipitation during the 20th century. In contrast, tree growth rates were significantly positively related to summer temperatures, neither of which increased markedly. The total aboveground biomass decreased from approximately 40tha -1 in the closed larch forest to 5tha -1 at the tree line. Our study demonstrates that ongoing climatic changes lead to an upslope expansion of forests in the remote Putorana Mountains, which alters the stand structure and productivity of the forest-tundra ecotone. These vegetation changes are very probably of minor importance for aboveground carbon sequestration, but soil carbon data are needed to estimate the impact of the forest expansion on the total ecosystem carbon storage.

Аннотация: As a description of altitude-belt zonality of wood vegetation, a model of ecological second-order transitions is proposed. Objects of the study have been chosen to be forest cenoses of the northern slope of Kulumyss Ridge (the Sayan Mauntains), while the results are comprised by the altitude profiles of wood vegetation. An ecological phase transition can be considered as the transition of cenoses at different altitudes from the state of presence of certain tree species within the studied territory to the state of their absence. By analogy with the physical model of second-order, phase transitions the order parameter is introduced (i.e., the area portion occupied by a single tree species at the certain altitude) as well as the control variable (i.e., the altitude of the wood vegetation belt). As the formal relation between them, an analog of the Landau's equation for phase transitions in physical systems is obtained. It is shown that the model is in a good accordance with the empirical data. Thus, the model can be used for estimation of upper and lower boundaries of altitude belts for individual tree species (like birch, aspen, Siberian fir, Siberian pine) as well as the breadth of their ecological niches with regard to altitude. The model includes also the parameters that describe numerically the interactions between different species of wood vegetation. The approach versatility allows to simplify description and modeling of wood vegetation altitude zonality, and enables assessment of vegetation cenoses response to climatic changes.

Аннотация: For a description of the successional processes in forest coenoses and the spatial distribution of tree species, an approach using phase transitions models is proposed. We introduced a variable equation and phase transition models that describe processes in forest coenoses. The analysis showed that the model considering processes in the forest as second-order phase transitions is in good agreement with the field data. The model parameters can be calculated from the data of field observations and used for prognosis calculations of successional processes in a forest and the distribution of important tree species in high-altitude forests. The proposed approach to the modeling of dynamic processes in the forest as phase transitions is universal and it greatly simplifies the task of constructing models of forest dynamics. © 2014 Pleiades Publishing, Ltd.

Аннотация: The results of the snow measurement at logged sites in fir-Siberian pine forests of the Yenisey Ridge in 2006–2011 are presented. Orographic and biotopic features of snow accumulation in the stands of different forest regeneration stages are considered. The snow cover depth and snow pack are determined by the altitude and topography of this region that form “barrier-shadow” effects. On the local level, the characteristics of snow cover are related to duration after logging, the species composition of young forests, and the logging technology.

Аннотация: The results of measurements of ground CO2 concentration in the middle taiga subzone of the Yenisei region of Siberia (the ZOTTO observatory) in 2009 to 2012 are presented. Specific features of CO2 variability over the altitude profile up to 301 m are accounted for by specific diurnal and seasonal features in the functioning of terrestrial ecosystems as well as by atmospheric processes. It has been shown that the significance of regional and global components increases with elevation, while the contribution of the underlying surface in the region of the observatory decreases. The observed gradient differences between CO2 concentrations recorded at the onset and at the end of the cold period are explained by seasonal changes in the height of the atmospheric boundary layer. Comparison of data obtained at the ZOTTO observatory and at monitoring stations in Canada and the North Atlantic has shown that general trends in the seasonal variability of CO2 are similar and that specific features of the processes under study are dependent on biogeographic characteristics of the study regions.

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: The influence of climate changes on larch (Larix sibirica Ledeb.) radial increment under conditions of a limited (forest steppe) and sufficient (high-altitude Kuznetsk Alatau, floodplain stands) humidification is considered. The relationship between growth index of larch trees (N = 257) and ecological and climatic variables is analyzed. In the forest steppe, with the onset of warming, a decrease in the aridity of the climate, an increase in the duration of the growing season (1980s), and an increase in the larch growth index followed by its depression in the 1990s have been observed. Radial-increment depression is caused by an increase in vapor-pressure deficit and arid climate due to a rising air temperature. In the 2000s, radial-increment fluctuations with average values not exceeding those before the beginning of current climate warming period occurred. In the highlands, since the 1970s, there has been a general increase in the larch radial increment closely associated with the main limiting factor of growth-air temperature. At the same time, in arid years, the radial-increment depression of larch trees in highland and floodplain larch forests is also noted. When implementing "hard" climate scenarios (RCP 6.0 and RCP 8.5), it is likely that the larch growth index in a forest steppe will decrease further and its increase in areas of sufficient moisture will be observed.

Аннотация: In the complex structure of the vertical altitudinal zonality of the Altai-Sayan mountain country, peat soils were almost not represented. The aim of this research was to develop a topographic series of peat soils of the Kuznetsk Alatau. The studied peatlands were confined to the basins of the Belyi Iyus and the Chernyi Iyus rivers and located at different hypsometric levels of the relief on the Eastern slope of the Kuznetsk Alatau, at 1543, 1087, 832, 622, 579 and 547m above sea level (See Fig. 1). As a criterion of vertical structural organization of soil, we used acid-base properties: water pH (water extract), salt pH (extract of 1M KCl) and general potential - nonexchangeable acidity (extract of 1M CH3COONa). The determined value of acidity was multiplied by an empirical coefficient 1.75. The sum of exchangeable cations (by Kappen-Hilkovits) was found in the extract of 0.1M HCl, in which the Ca2++Mg2+ was determined by complexometric titration. According to the difference between the sum of exchangeable cations and Ca2++Mg2+, we identified the content of other (unidentified) cations. The degree of soil saturation with bases, expressed in %, was calculated as the proportion of exchangeable bases in 0.1M HCl solution to the sum (exchangeable bases + nonexchangeable acidity). The V-diagrams, constructed on the basis of water pH, salt pH and saturation of soil absorbing complex (SAC) with exchangeable calcium and magnesium, describe the acidic trace of soil formation and simulate the acidification of top soil horizons in the course of peat genesis (See Fig. 2). High-precision regression model was proposed for the prediction of exchangeble acidity value (pHKCl) by the value of active acidity (pHH2O).Using the methods of multivariate statistical analysis (discriminant, multidimensional scaling), we grouped peat soils into three clusters with acid-base characteristics. The parameter of SAC saturation by alkaline-earth cations and pH salt value makes the dominant contribution to the organization of peat soil clusters with a final prediction 89% (See Table 3, Fig. 4). In the structure of vertical soil zones of the Altai-Sayan mountain country, particularly of the Eastern slopes of the Kuznetsk Alatau, the geochemical associations (clusters) of peat soils were identified: a) acidic and unsaturated by calcium and magnesium (<30-50%) on the whole profile within the boundaries of alpine tundra and subalpine complexes at the altitude of 1500-1100 m; b) slightly acidic and slightly saturated with bases (50-70%) within the mountaintaiga zone of dark coniferous forests 1100-800 m a.s.; c) neutral and moderately saturated with alkaline-earth base (70-90%) associations of peat soils within the zone of subtaiga-forest-steppe 800-500 m a.s. (See Table 4). Chorological organization of peat soils is in accordance with the hydrochemical zoning of underground waters and high-zone structure of the vegetation cover at automorphic sites. However, in the forest zone of wetlands of the Kuznetsk Alatau eastern slope, regardless of acid-base properties of peat soils, spruce forests mainly form, reflecting the main characteristics of soil hydromorphism. In this regard, the status of indigenous groups of swamp spruce forests can be considered as sufficient objective criteria of a regional climate change towards dryness. © 2018 Tomsk State University.

Аннотация: Key message: We investigate the intra-annual growth patterns of Chinese pine in Helan Mountains, confirming that regional water status plays a dominated role in stem radial increment. Abstract: The associations between environmental conditions and stem radial increment (SRI) are useful for assessing a species’ growth response to climate change. Intra-annual SRI dynamics of Chinese pine (Pinus tabulaeformis) were monitored half-hourly by automatic point dendrometer during the growing season (May–September) in 2016 and 2017 at two altitudes in the Helan Mountains, northern central China. Here, we compared the seasonal growth patterns between two altitudes and 2 years. Trees at low altitude are characterized by earlier cessation, shorter growing season, and lower growth rate, resulting in less annual growth, which may reflect the greater drought intensified by rising temperature at low altitude. June precipitation significantly affected tree growth rate. The xylem growth was active when daily mean air temperature was 9.9 °C at our study region for P. tabulaeformis in an arid environment. During the growing season, daily stem radial increment showed a significantly positive correlation with precipitation and a negative correlation with daily air temperature at all altitudes. Climatic variables associated with tree water status, namely precipitation, vapor pressure deficit, and relative humidity, played important roles in daily stem radial increment as the same result as a linear mixed model. These factors drive the complex physiological processes of stem radial increment by influencing the moisture available to the tree. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.

Аннотация: Cryogenic oligotrophic (Hyperdystric Cryic Fibric Histosols), oligomesotrophic (Dystric Fibric Histosols), mesoeutrophic (Oligeoeutric Fibric Histosols), and eutrophic (Hypereutric Fibric Histosols) peat soils were studied on the eastern slopes of the Kuznetsk Alatau Ridge (Republic of Khakassia). Their altitudinal differentiation was examined, and clustering according to the qualitative and quantitative composition of organic matter was performed. The most informative indicators of similarity and/or differences between the clusters were suggested. The group composition of organic matter was analyzed using acid and alkaline extractions. Multivariate statistical analyses (cluster, discriminant, and canonic) were applied for evaluation of the humus status. Indicators of organic matter status, which are significant for discrimination form two discriminant functions. Function 1 discriminates between the clusters (80%) and includes the indicators characterizing the depths of peat soil transformation: humification degree ( n-ary sumation HA + n-ary sumation FA), type of humus (C-HA/C-FA ratio), and ratio between the fractions of humic acids extracted by 0.02 N NaOH and 0.1 N NaOH (C-0.02 n NaOH/C-0.1 n NaOH). Function 1 clearly separates clusters of permafrost-affected oligotrophic peat soils of the alpine tundra zone (>1460 m a.s.l.) from oligo-mesotrophic peat soils of the subalpine zone (1087 m a.s.l.). Function 2 discriminates (at the 16% difference level) the clusters of peat soils of the forest zone-meso-eutrophic peat soils of the taiga zone (832 m a.s.l.) and eutrophic peat soils of the subtaiga-forest-steppe zone (622-573 m a.s.l.); it also includes hemicellulose and cellulose-characteristics of the initial state of peat-forming plants. The humus status of the mountainous peat soils corresponds to their diagnostics according to the base saturation and pH criteria and reflects a general pedogenetic trend in mountains: an increase in the humus content in soils with the altitude, which was earlier shown for mineral soils.

Аннотация: Stratospheric volcanic eruptions have had significant impacts on the radiation budget, atmospheric and surface temperatures, precipitation and regional weather patterns, resulting in global climatic changes. The changes associated with such eruptions most commonly result in cooling during several years after events. This study aimed to reveal eco-physiological response of larch trees from northeastern Yakutia (YAK), eastern Taimyr (TAY) and Altai (ALT) regions to climatic anomalies after major volcanic eruptions CE 535, 540, 1257, 1641, 1815 and 1991 using new multiple tree-ring parameters: Tree-ring width (TRW), maximum latewood density (MXD), cell wall thicknesses (CWT), ?13C and ?18O in tree-ring cellulose. This investigation showed that TRW, CWT, MXD and ?18O chronologies recorded temperature signal, while information about precipitation and vapor pressure deficit was captured by ?13C chronologies. Sunshine duration was well recorded in ?18O from YAK and ALT. Tree-ring parameters recorded cold, wet and cloudy summer anomalies during the 6th and 13th centuries. However, significant summer anomalies after Tambora (1815) and Pinatubo (1991) eruptions were not captured by any tree-ring parameters. © 2020 JMIR Human Factors.All right reserved.

Аннотация: Here we report about the discovery of the poplar leaf miner, Phyllonorycter populifoliella (Treitschke) in India. The mines of this micromoth were found in noticeable density on the leaves of poplar, Populus sp. (Salicaceae) in the northern mountainous region Ladakh in 2017-2018. We provide short morphological diagnosis, describe bionomics and analyze molecular data of Ph. populifoliella from India comparing sequences with those from other countries in Eurasia where the species is known as native. We also illustrate male and female genitalia, an adult of the moth, the leaf mines and the infestation plot in Ladakh, and discuss the occurrence of the species in the country. © 2021 Magnolia Press.

Аннотация: This research is dedicated to solving an urgent problem associated with the large-scale destruction of taiga forests by Siberian silk moth (Dendrolimus sibiricus) outbreaks. The dynamics of the damage to dark coniferous forest stands induced by the Siberian silk moth outbreaks in mid-altitude mountains were studied. A hypothesis was formulated based on the fundamental influence of the orography on the phytophage’s dispersal within the landscape, along with the climate, which acts as a secondary predictor—a catalyst for outbreaks. The study was carried out using Landsat?8 satellite imagery time-series (from 2018 to 2020). The data were verified using a field forest pathological survey of the territory. An assessment of the defoliated forest area and damage association with the landscape was carried out using an Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) digital elevation model. The assessment was aimed to detail the forecast parameters for an outbreak development in mid-altitude mountains using the orographic features—altitude, terrain slope, and slope aspect. Early warnings of phytophagous insect outbreaks in mountain southern taiga should be focused on the permanent monitoring of dark coniferous stands of the mossy group of forest types, covering altitude levels from 400 to 600 m, located on gentle terrains and slopes of up to 15 degrees. The greatest vulnerability to phytophage impacts was characterized as areas located at altitudes from 400 to 600 m. The upper limit of D. sibiricus distribution was 900 m above sea level. The results obtained provide comprehensive information on the Siberian silk moth potential reserves within the study area with the possibility of extrapolation to similar territories. The data will make it possible to model pest outbreaks based on orography and improve the forest pathological monitoring methods at the regional level. © 2021 by the authors.
