Аннотация: The results show enormous changes in the vegetation cover of Siberia for a warmed climate. Southern vegetation types such as southen taiga, subtaiga, and forest-steppe are expected to expand from about 10% to 70% coverage. This increase in coverage would be largely at the expense of northern and middle taiga each of which would then occupy less than 20%. Some contemporary climatypes are projected to diappear from Siberia while others common elsewhere would evolve. To mitigate these effects, climatypes should be transferred today to the expected future location of their climatic optima, a distance that is likely to approach 700-1200 km for Siberian species of larches.

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: 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: 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: The data of experimental studies on the after-fire digression of subtaiga forest-steppe pine forests in the Southwestern Baikal Region are analyzed. Ground fires of the litter-humus type are ascertained to be the most destructive factor in the dynamics of pine forests. The effect of a ground fire is accompanied with the drying of trees, and the vital capacity of those that survived the fire depends on the severity of fire damages. The characteristic of the lower vegetation layers and its dynamics under the effect of moderately intense fires are presented. Ground fires are shown to negatively affect the change in the reserve qualitative fractional structure of organogenic soil layers and their chemical composition.

Аннотация: Data from the " Biome" information system were used to construct an ordination of zonal categories of vegetation cover in southern Siberia along the axes of heat supply and continentality. The changes of climate that occurred from the end of the 1960. s to 2007 are estimated. It is shown that they can lead to transformation of the composition of potential forest vegetation in a number of regions. We discuss the forecasted and observed variants of long-term successions in different sectoral-zonal classes of subtaiga and forest-steppe, including the risk of a reduction in the areas of separate forest-forming species.

Аннотация: An equilibrium model driven by climatic parameters, the Siberian Vegetation Model, was used to estimate changes in the phytomass of Siberian vegetation under climate change scenarios (CO2 doubling) from four general circulation models (GCM's) of the atmosphere. Ecosystems were classified using a three-dimensional climatic ordination of growing degree days (above a 5В°C threshold), Budyko's dryness index (based on radiation balance and annual precipitation), and Conrad's continentality index. Phytomass density was estimated using published data of Bazilevich covering all vegetation zones in Siberia. Under current climate, total phytomass of Siberia is estimated to be 74.1 В± 2.0 Pg (Petagram = 1015 g). Note that this estimate is based on the current forested percentage in each vegetation class compiled from forest inventory data. Moderate warming associated with the GISS (Goddard Institute for Space Studies) and OSU (Oregon State Univ.) projections resulted in a 23-26 % increase in phytomass (to 91.3 В± 2.1 Pg and 93.6 В± 2.4 Pg, respectively), primarily due to an increase in the productive Southern Taiga and Subtaiga classes. Greater warming associated with the GFDL (General Fluid Dynamics Laboratory) and UKMO (United Kingdom Meteorological Office) projections resulted in a small 3-7 % increase in phytomass (to 76.6 В± 1.3 Pg and 79.6 В± 1.2 Pg, respectively). A major component of predicted changes using GFDL and UKMO is the introduction of a vast Temperate Forest-Steppe class covering nearly 40 % of the area of Siberia, at the expense of Taiga; with current climate, this vegetation class is nearly non-existent in Siberia. In addition, Subboreal Forest-Steppe phytomass doubles with all GCM predictions. In all four climate change scenarios, the predicted phytomass stock of all colder, northern classes is reduced considerably (viz., Tundra, Forest-Tundra, Northern Taiga, and Middle Taiga). Phytomass in Subtaiga increases greatly with all scenarios, from a doubling with GFDL to quadrupling with OSU and GISS. Overall, phytomass of the Taiga biome (Northern, Middle, Southern, and Subtaiga) increased 15 % in the moderate OSU and GISS scenarios and decreased by a third in the warmer UKMO and GFDL projections. In addition, a sensitivity analysis found that the percentage of a vegetation class that is forested is a major factor determining phytomass distribution. From 25 to 50 % more phytomass is predicted under climate change if the forested proportion corresponding to potential rather than current vegetation is assumed.

Аннотация: Since information on the distribution of the white-toothed shrew in Central Siberia is scarce, the objective of the present work was to present new data on their distribution and habitat restrictions. The data on 10 new records of the white-toothed shrew group Crocidura suaveolens Pallas 1811 - Crocidura sibirica Dukelsky 1930 in Central Siberia are presented. Most of the records stem from the right bank of Yenisei River, where almost no information on their distribution was available. Genetic and morphological analyses confirmed the identity of all records to the Siberian white-toothed shrew. Based on this, with a high degree of confidence one can say that the distribution of the white-toothed shrew is not confined to the left bank of the Yenisei River alone, but it also covers the northern slopes of the Eastern Sayan Mountains and the Yenisei Ridge. In contrast to the small shrews associated with desert and steppe habitats, the white-toothed shrew in the Minusinskaya Siberian Basin and on the right bank of the Yenisei is confined to subtaiga habitats (light coniferous small-leaved forests with herbs). The animals are distributed sporadically, with extremely low numbers and are captured but individually.

Аннотация: Changes in soil microbial processes and phytocenotic parameters were studied in clearings made for power transmission lines in the subtaiga and southern taiga of Central Siberia. In these clearings, secondary meadow communities play the main environmental role. The substitution of meadow vegetation for forest vegetation, the increase in the phytomass by 40–120%, and the transformation of the hydrothermic regime in the clearings led to the intensification of the humus-accumulative process, growth of the humus content, reduction in acidity and oligotrophy of the upper horizons in the gray soils of the meadow communities, and more active microbial mineralization of organic matter. In the humus horizon of the soils under meadows, the microbial biomass (Cmicr) increased by 20–90%, and the intensity of basal respiration became higher by 60–90%. The values of the microbial metabolic quotient were also higher in these soils than in the soils under the native forests. In the 0- to 50-cm layer of the gray soils under the meadows, the total Cmicr reserves were 35–45% greater and amounted to 230–320 g/m3; the total microbial production of CO2 was 1.5–2 times higher than that in the soil of the adjacent forest and reached 770–840 mg CO2-C/m3 h. The predominance of mineralization processes in the soils under meadows in the clearings reflected changes in edaphic and trophic conditions of the soils and testified to an active inclusion of the herb falloff into the biological cycle. © 2017, Pleiades Publishing, Ltd.

Аннотация: Data on postpyrogenic dynamics of soils under mountainous taiga cedar (Pinus sibirica) and pine (Pinus sylvestris) forests and subtaiga-forest-steppe pine (Pinus sylvestris) forests in the Baikal region are analyzed. Ground litter-humus fires predominating in this region transform the upper diagnostic organic soil horizons and lead to the formation of new pyrogenic organic horizons (Opir). Adverse effects of ground fires on the stock, fractional composition, and water-physical properties of forest litters are shown. Some quantitative parameters of the liquid and solid surface runoff in burnt areas related to the slope gradient, fire intensity, and the time passed after the fire are presented. Pyrogenic destruction of forest ecosystems inevitably induces the degradation of mountainous soils, whose restoration after fires takes tens of years. The products of soil erosion from the burnt out areas complicate the current situation with the pollution of coastal waters of Lake Baikal.

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.

УДК	630.14.351

Аннотация: Анализируются данные экспериментальных исследований по постпирогенной динамике подстилки в горно-таежных кедровых (Pinus sibirica), сосновых (Pinus sylvestris) и подтаежно-лесостепных сосновых (Pinus sylvestris) лесах Прибайкалья. Низовые пожары, преобладающие в данном регионе, трансформируют типодиагностические поверхностные органогенные горизонты почв, приводят к формированию новых органогенных пирогенных горизонтов (Opir; OLpir; OL/Opir; OApir). Показано негативное воздействие низовых пожаров на изменения мощности, запасов, влагоемкости и качественного фракционного состава лесных подстилок. Приведены данные по зольному химическому составу подстилок, а также по содержанию подвижных форм микроэлементов. Обнаружена тенденция уменьшения концентрации подвижных элементов в органогенных горизонтах от таежного кедрового к подтаежно-лесостепному сосновому высотно-поясному комплексу (ВПК) типов леса. Установлено, что лесные пожары приводят к значительным количественным и качественным изменениям химического состава поверхностных органогенных пирогенных горизонтов, особенно это проявляется в трансформации лабильных их свойств (рН, состав обменных катионов, валовых и подвижных форм азота и др.).
The data of experimental studying the post-pyrogenic dynamics of litter in mountain- taiga cedar (Pinus sibirica), pine (Pinus sylvestris) and subtaiga- forest-steppe pine (Pinus sylvestris) forests in the Pribaikalie region are analyzed in the paper. Ground fires prevailing in this region transform the type-diagnostic surface organogenic horizons of soils, result also in the formation of new pyrogenic horizons (Opir; OLpir; OL/Opir; OApir). The negative impact of ground fires on the change in power, reserves, moisture capacity and qualitative fractional composition of forest litters has been shown here as well. The data of ash chemical composition of litters as well as the content of mobile forms of microelements is given too. The tendency of reducing concentration of mobile elements in organogenic horizons from the taiga cedar altitudinal-belt complex (ABC) to the subtaiga – forest steppe pine ABC of forest types has been clearly revealed. It was established that forest fires result in large quantitative and qualitative changes of the chemical composition of surface organogenic pyrogenic horizons, and especially it shows itself in transformation of their labile properties (рН, composition of exchange cations, gross and mobile forms of nitrogen etc.).

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: В работе обосновывается необходимость совершенствования принципов использования природной основы, предназначенной для экосистемного управления лесами в горных условиях, используя для этого все накопленные знания, региональные базы данных и новые возможности дистанционных методов. На примере гор Алтае-Саянского экорегиона приводятся результаты использования спектральных признаков растительности с привлечением теплового диапазона при анализе высотно-поясной дифференциации лесного покрова. Так, в приенисейской части Саян отчетливо проявляются лесостепной, подтаежный светлохвойно-мелколиственный, горно-черневой темнохвойный, горно-таежный (с вариантами по составу лесообразователей) и подгольцово-субальпийский классы высотно-поясных комплексов (ВПК). Для каждого из них должны применяться свои системы ведения лесного хозяйства, связанные с природными особенностями лесов и их целевым назначением. Актуальной задачей для горного лесоводства и в целом многоцелевого лесопользования является совершенствование эколого-географической основы и ее картографическое воплощение в виде среднемасштабных карт с отражением не только формационного состава лесного покрова, но и высотно-поясных классов экосистем. Современные спутниковые системы дистанционного зондирования в сочетании с ГИС-технологиями открывают возможности для совершенствования методов инвентаризации, мониторинга, изучения географии лесного покрова, меняющейся под воздействием внешних факторов. Это позволяет перейти к внедрению в практику лесоуправления качественной природной основы, востребованной на всех уровнях лесного планирования – от планов освоения лесных участков до лесных планов субъектов Российской Федерации.
This study was performed to prove the necessity for the enhancement of principles of natural basis utilization for the ecosystem-focused forest management in mountainous conditions, using all the collected knowledge, regional data bases and the new remote sensing facilities. The results of using of the spectral features of the vegetation for studying the altitudinal differenciation of forest cover while also employing the thermal sensing, were shown on the example of the Altai-Sayan mountain region. Thus, in the Yenisei part of the Sayans forest-steppe, subtaiga, light coniferous-small-leaved-deciduous forest, mountain dark coniferous, mountain taiga and subalpine classes of altitudinal zones can be defined. For each of those separate systems of forest management should be employed, with taking into account natural features of those forests and their management purpose. A relevant task for the mountain forestry and the multipurpose forest use in general is the enhancement of the ecological and geographical basis and its cartographic realization in middle-scale maps, reflecting not only the formational composition of forest cover, but also the altitudinal ecosystems classes. Modern satellite systems, in coupled with GIS-technologies open new possibilities for the forest cover inventory, monitoring and study methods. It allows us to start implementing a qualitative natural basis into forest management practices, that is currently highly relevant on all levels of forest planning from single forest plot exploitation projects to the forest plans of the Russian Federation subjects.

Аннотация: В статье рассматриваются вопросы воздействия на природную среду утилизации боеприпасов на военных полигонах. Приводятся результаты комплексных исследований (почвы, растительности, мелких млекопитающих), проводившихся на двух полигонах: в Красноярской лесостепи (№ 1), где в 2013 г. закончена утилизация снарядов, и в Канской подтайге (№ 2), где с 1980 г. утилизация боеприпасов продолжается. Научная новизна работы заключается в междисциплинарном рассмотрении вопроса с привлечением инструментальных методов исследования и спутниковых данных. Установлено, что под воздействием взрывов формируется беллигеративный ландшафт, образуются воронки, которые заполняются водой. В результате выноса грунта (почвы и нижележащих почвообразующих пород) при взрывах изменяются структурная организация и физические свойства почв на расстоянии до 15 м от края воронки. Отмечено, что формирование сообществ происходит в течение длительного времени и начинается с пионерной стадии вследствие осыпания стенок воронок. Прямое воздействие взрывов на животное население проявляется во внутреннем кровоизлиянии и нарушении почечной ткани у мелких млекопитающих, а косвенное - в изменении биотопа: разрыхлении почвы и образовании водоемов на дне воронок, что способствует образованию локальных поселений полевки-экономки Microtus oeconomus Pallas. По результатам исследований определены параметры и пространственная приуроченность местообитаний, нарушенных подрывом боеприпасов, что необходимо для организации и ведения мониторинга этого техногенного воздействия. Данная проблема мало изучена и требует дальнейших исследований
The article highlights the impact of ammunition at military ranges on the natural environment of disposal. The results of complex studies are presented (soil, vegetation, small mammals) for two sites: in the Krasnoyarsk forest-steppe (N. 1), where in 2013 the disposal of projectiles was completed and in Kansk subtaiga (N. 2), where the disposal of projectiles continue. The scientific novelty of the work lies in the interdisciplinary consideration of the issue using instrumental research methods and satellite data. It was found that under the influence of explosions, a belligerative landscape is formed, funnels are formed, which are filled with water. As a result of the removal of soil (soil and underlying parent rocks) during explosions, the structural organization and physical properties of soils change at a distance of up to 15 m from the edge of the funnel. The authors note that the formation of communities takes a long time and begins from the pioneer stage as result of shedding of the walls an erosional succession type occurs in the blast craters. The direct impact of explosions is manifested as internal hemorrhage and impaired kidney in small mammals. An indirect effect is manifested in a change in the biotope: loosening the soil and the formation of reservoirs at the bottom of the craters, contributes to the formation of local settlements of tundra voles Microtus oeconomus Pallas. According to the results of the research, the parameters and spatial confinedness of disturbed by the explosions habitats were determined, which is necessary for the organization and monitoring of this anthropogenic impact. This problem has been little studied and requires further research
