Аннотация: Warming of the permafrost accompanied by the release of ancient soil organic carbon is one of the most significant environmental threats within the global climate change scenario. While the main sites of permafrost carbon processing and its release to the atmosphere are thermokarst (thaw) lakes and ponds, the main carriers of carbon and related major and trace elements from the land to the Arctic ocean are Russian subarctic rivers. The source of carbon in these rivers is atmospheric C consumed by chemical weathering of rocks and amplified by plant uptake and litter decomposition. This multidisciplinary study describes results of more than a decade of observations and measurements of elements fluxes, stocks and mechanisms in the Russian boreal and subarctic zone, from Karelia region to the Kamchatka peninsula, along the gradient of permafrost-free terrain to continuous permafrost settings, developed on various lithology and vegetation types. We offer a comprehensive, geochemically-based view on the functioning of aquatic boreal systems which quantifies the role of the following factors on riverine element fluxes: (1) the specificity of lithological substrate; (2) the importance of organic and organo-mineral colloidal forms, notably during the snowmelt season; (3) the phenomenon of lakes seasonal overturn; (4) the role of permafrost within the small and large watersheds; and (5) the governing role of terrestrial vegetation in element mobilization from rock substrate to the river. Care of such a multiple approach, a first order prediction of the evolution of element stocks and fluxes under scenario of progressive warming in high latitudes becomes possible. It follows the increase of frozen peat thawing in western Siberia will increase the stocks of elements in surface waters by a factor of 3 to 10 whereas the increase of the thickness of active layer, the biomass and the primary productivity all over permafrost-affected zone will bring about a short-term increase of elements stocks in labile reservoir (plant litter) and riverine fluxes by a factor of 2. The change of the plant productivity and community composition under climate warming in central Siberia will be the most important factor of major and trace element fluxes increase (probably a factor of 2) from the soil to the river and, finally, to the Arctic Ocean.

Аннотация: To answer the question "Has the recent warming no analogues in the Siberian north?" we analyzed larch tree samples (. Larix gmelinii Rupr.) from permafrost zone in the eastern Taimyr (TAY) (72В°N, 102В°E) using tree-ring and stable isotope analyses for the Climatic Optimum Period (COP) 4111-3806 BC and Medieval Warm Period (MWP) 917-1150 AD, in comparison to the recent period (RP) 1791-2008 AD.We developed a description of the climatic and environmental changes in the eastern Taimyr using tree-ring width and stable isotope (?13C, ?18O) data based on statistical verification of the relationships to climatic parameters (temperature and precipitation).Additionally, we compared our new tree-ring and stable isotope data sets with earlier published July temperature and precipitation reconstructions inferred from pollen data of the Lama Lake, Taimyr Peninsula, ?18O ice core data from Akademii Nauk ice cap on Severnaya Zemlya (SZ) and ?18O ice core data from Greenland (GISP2), as well as tree-ring width and stable carbon and oxygen isotope data from northeastern Yakutia (YAK).We found that the COP in TAY was warmer and drier compared to the MWP but rather similar to the RP. Our results indicate that the MWP in TAY started earlier and was wetter than in YAK. July precipitation reconstructions obtained from pollen data of the Lama Lake, oxygen isotope data from SZ and our carbon isotopes in tree cellulose agree well and indicate wetter climate conditions during the MWP.Consistent large-scale patterns were reflected in significant links between oxygen isotope data in tree cellulose from TAY and YAK, and oxygen isotope data from SZ and GISP2 during the MWP and the RP.Finally, we showed that the recent warming is not unprecedented in the Siberian north. Similar climate conditions were recorded by tree-rings, stable isotopes, pollen, and ice core data 6000 years ago. В© 2013 Elsevier Ltd.

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: A peat profile, 5.5 m in depth, laid in a bog complex comprising frost mounds, bog hollows, and lakes was studied. This bog complex was located in one of the most swamped regions of the middle taiga of the West Siberian Plain. Botanical and spore-pollen analyses of the peat field were conducted. Across the thickness of the peat deposit, 17 points at 25-cm intervals were dated by the radiocarbon method. The dynamics of vegetation and climate during the past 9500 years were determined. It was revealed that, during this period, the rate of peat accumulation constantly tended to decrease, with some fluctuations. The results of mathematical and ecological simulation of this process predict that it will cease in another 1000 years. В© 1997 MAHK Hayka/Interperiodica Publishing.

Аннотация: Prehistoric and early historic human cultures are known to be closely connected to and dependent on their natural environments. We test the hypothesis that climate change influenced the means of subsistence of ancient tribes and favored agricultural or cattle herding economic strategies. Our study area is the Khakass-Minusinsk Hollow, located in the foothills of the Sayan Mountains, south-central Siberia, which was, for a few millennia, a buffer zone for human migrations across the Great Eurasian Steppe. Three different methods (the Montane BioClimatic Model, MontBCliM; the biomization method; and the actualizm method) are employed to reconstruct vegetation taken from the fossil pollen of sediment cores in two mountain lakes at eleven time slices related to successive human cultures back to the mid-Holocene. MontBCliM model is used inversely to convert site paleo-vegetation into site paleo-climates. Climate-based regression models are developed and applied to reconstructed climates to evaluate possible pasture and grain crops for these time slices. Pollen-based reconstructions of the climate fluctuations uncovered several dry periods with steppe and forest-steppe and wetter periods with forests since 6000 BP. Grasslands increased by an order of magnitude during the dry periods and provided extensive open space suitable for pastoralism; however, both grain and pasture yields decreased during these dry periods. During wetter climates, both grain and pasture yields increased twofold and supported more fixed human settlements centered around farming and cattle herding. Thus, the dry periods favored pastoralist rather than farming activities. Conversely, tribes that practiced agriculture had some advantage in the wet periods. © 2014 IOP Publishing Ltd.

Аннотация: A solar-terrestrial relations were examined using millennium-scale paleoclimatic data from the Central Asia mountain region. The paleoclimatic data were based on nonvarved lake sediments of the Teletskoye lake and temperature-sensitive long tree-ring width chronologies from the Altai region (Altai Mountains, South Siberia, Russia) in the late Holocene (2000 years). Also a solar-activity during late Holocene was used to analyze. Core of the bottom sediments from the Teletskoe lake (Altai Mountains) were investigated using scanning X-ray fluorescent analysis method with synchrotron radiation (spatial resolution is 0.1 mm). A method ensemble empirical mode decomposition (EEMD) was used to extract low-frequency variability from all presented paleoarchives. The results obtained for paleodata indicate palaeoclimatic oscillations in the range of the de Vries (Suess) (?200-year) solar cycles through the late Holocene. Evidence of the influence of solar activity on global climatic processes and terrestrial ecosystems is discussed.

Аннотация: Quantitative dynamics, water surface area, and water level of lakes in the Trans-Baikal forest-steppe zone have been studied by spectroradiometry (Landsat satellite), gravimetry (GRACE satellite), and altimetry (Envisat satellite). The number of lakes and their water surface area correlated with precipitation (r = 0.84-0.85), summer and annual temperature (r =-0.77 to-0.9), and drought index (r = 0.95-0.97). During extremely dry periods (2006-2010), the number of lakes decreased by four (compared to 1989) and their water surface area decreased by three (compared to 2000). The rate of change in the water level of the lakes (periods of similar to 29 years) was determined.

Аннотация: Methane (CH4) production, oxidation, and emission were studied in ponds of the permafrost-affected polygonal tundra in northeast Siberia. Microbial degradation of organic matter in water-saturated soils is the most important source for the climate-relevant trace gas CH4. Although ponds and lakes cover a substantial fraction of the land surface of northern Siberia, data on CH4 fluxes from these water bodies are scarce. Summer CH4 fluxes were measured with closed chambers at the margins of ponds vegetated by vascular plants and in their centers without vascular plants. Furthermore, CH4 and oxygen concentration gradients, stable carbon isotope signatures of dissolved and emitted CH4, and microbial CH4 production and CH4 oxidation were determined. Mean summer fluxes were significantly higher at the margins of the ponds (46.1 ± 15.4 mg CH4 m-2 d-1) than at the centers (5.9 ± 8.2 mg CH4 m-2 d-1). CH4 transport was dominated by diffusion in most open water sites, but substantial ebullitive fluxes (12.0 ± 8.1 mg CH4 m-2 d-1) were detected in one pond. Plant-mediated transport accounted for 70 to 90% of total CH4 fluxes above emerged vegetation. In the absence of vascular plants, 61 to 99% of the CH4 produced in the anoxic bottom soil was consumed in a layer of the submerged moss Scorpidium scorpioides, which covered the bottoms of the ponds. The fraction of CH4 oxidized was lower at sites with vascular plants since CH4 was predominantly transported through their aerenchyma, thereby bypassing the CH4 oxidation zone in the moss layer. These results emphasize the importance of moss-associated CH4 oxidation causing low CH4 fluxes from the studied Siberian ponds. © 2015. American Geophysical Union. All Rights Reserved.

Аннотация: Siberian pine (Pinus sibirica) and fir (Abies sibirica) (so called “dark needle conifers”, DNC) showed decreased radial growth increment within the Lake Baikal watershed since the 1980s with increasing mortality recorded since the year 2000. Tree ring width was strongly correlated with vapor pressure deficit, aridity and root zone moisture. Water stress from droughts made trees more susceptible to insect attacks causing mortality in about 10% of DNC stands within the Lake Baikal watershed. Within Siberia DNC mortality increased in the southern part of the DNC range. Biogeographically, tree mortality was located within the DNC – forest-steppes transition. Tree mortality was significantly correlated with drought and soil moisture anomalies. Within the interior of the DNC range mortality occurred within relief features with high water stress risk (i.e., steep convex south facing slopes with shallow well-drained soils). In general, DNC mortality in Siberia was induced by increased aridity and severe drought (inciting factors) in synergy with biotic attacks (contributing factor). In future climate scenarios with predicted increase in aridity DNC could be eliminated from the southern part of its current range and will be replaced by drought-resistant conifers and broadleaf species (e.g., Larix sibirica, Pinus silvestris, and Betula pubescence). © 2016

Аннотация: For the first time in the Middle Ob Basin, new data of importance for evaluating the quality of swamp and river water were obtained, characterizing the microcomponent composition of extractive organic compounds. More than 150 compounds of natural genesis were identified. The water of oligotrophic and mesotrophic bogs shows widest diversity and maximal, almost equal masses of extractable organic substances, averaging 13 357 ng/L. In the water of eutrophic bogs and taiga rivers, this characteristic is five times lower; and that in lakes is lower by more than an order of magnitude. The amount of extractive trace components is closely correlated with the concentration of water-soluble carbon of humic nature. It was established that the natural water of taiga zone identical in terms of the fulvate type differs in the composition of organic trace components and can be grouped into four clusters: (a) water of oligotrophic bogs, (b) water of mesotrophic bogs, (c) river water, and (d) water of eutrophic bogs and bog lakes.

Аннотация: Laboratory experiments were conducted in a hermetically sealed growth chamber with two soil samples obtained from the arctic tundra zone with different levels of moisture. Samples were maintained at a growing season typical of the region from which they were taken, and for the sample with a high level of moisture it was made twice: with the temperature in accord with natural conditions and one increased by 2 degrees C. It has been shown that heating of the overmoistened tundra soil by 2 degrees C can increased the average carbon dioxide emissions by almost two times (from 75 to 100-150 mg m(-2) h(-1)). Upon the application of heat, no significant increase in methane emission was observed.

Аннотация: The increasing trend of large carnivore attacks on humans not only raises human safety concerns but may also undermine large carnivore conservation efforts. Although rare, attacks by brown bears Ursus arctos are also on the rise and, although several studies have addressed this issue at local scales, information is lacking on a worldwide scale. Here, we investigated brown bear attacks (n = 664) on humans between 2000 and 2015 across most of the range inhabited by the species: North America (n = 183), Europe (n = 291), and East (n = 190). When the attacks occurred, half of the people were engaged in leisure activities and the main scenario was an encounter with a female with cubs. Attacks have increased significantly over time and were more frequent at high bear and low human population densities. There was no significant difference in the number of attacks between continents or between countries with different hunting practices. Understanding global patterns of bear attacks can help reduce dangerous encounters and, consequently, is crucial for informing wildlife managers and the public about appropriate measures to reduce this kind of conflicts in bear country.

Аннотация: Приведены результаты полувекового изучения природных пожаров в Забайкалье. Выполнены стационарные экс периментальные исследования пожароопасности растительности по всем высотным поясам, репрезентативным ландшафтным местностям и типам леса. Маршрутные исследования проведены в разных природных округах. На про тяжении двух сезонов осуществлен авиамониторинг ландшафтных пожаров. Прослежены долговременные последствия пожаров на Байкальской природной территории и в Центральном Забайкалье. Проанализированы пирологические режимы в растительных комплексах, по каждому из которых определена длительность пожароопасного состояния как суммарная за весь сезон, так и непрерывная за период пожарного максимума. Характеристики режимов по вы сотным поясам приведены в трех вариантах в зависимости от количества осадков за сезон (обычный, засушливый, влажный). Выявлено, что ландшафтные пожары возникают при интенсивном и экстремальном режимах, когда устанавливается исключительная, по сравнению с сопредельными регионами, пирологическая монотонность расти тельных комплексов на большей части территории. В подобной ситуации практически отсутствуют естественные препятствия для огня, кроме широких рек, озер и гребней горных хребтов. Высокая горимость лесов обусловлена пре обладанием в их составе светлохвойных насаждений. Стремительному распространению пожаров способствуют сухие травостои и заросли пожароопасных кустарников, по которым огонь движется почти со скоростью ветра. Установ лено, что некошеные луга, заброшенные выпасы и пашни у поселковых околиц чреваты опустошительными пожарами не только в лесах, но и в населенных пунктах. В ситуации, подобной возникшей в 2015 г., ландшафтные пожары превращаются в природную катастрофу с тяжелыми лесоэкологическими последствиями. Уцелевшие древостои снижа ют продуктивность, изреживаются, а далее подвержены все более усугубляющейся дигрессии от последующих огневых воздействий. На гарях происходит локальное обезлесение, либо длительная смена хвойных насаждений лиственными. Грядущий сток с обширных выгоревших площадей может усугубить загрязнение оз. Байкал. Сделан вывод, что при влечение резервов МЧС для устранения последней огненной стихии в Прибайкалье оказалось малополезным вследствие запоздания. Альтернативой представляется заблаговременное прогнозирование высокого риска возникновения ланд шафтных пожаров с целью оперативной ликвидации возгораний, чтобы оперативно тушить все загорания при уме ренных затратах, не допуская их превращения в природную катастрофу.
This paper presents results of wildfire studies conducted Transbaikalia over the last five decades. Station-based experimen tal investigations into fire hazards of vegetation accomplished at the regional forest fire stations during those years covered all altitudinal vegetation zones, representative landscape localities and forest types. Route investigations were made in different natural areas. Arial monitoring of landscape fires was used during two fire seasons. Long-term effects of fires in the Baikal Natural Area and in Central Transbaikalia were investigated. Fire regimes in vegetation complexes were analyzed and for each of them the duration of the fire hazard was determined both as the total duration for the entire season and as a continuous duration for the period of the fire maximum. Characteristics of the regimes for the altitudinal belts are provided in three versions according to precipitation amounts for a season (normal, dry and wet). It is found that forest fires occur in intensive and extreme fire regimes when most of the vegetation complexes of the region become exceptionally hazardous as compared to adjacent areas. In such a situation, there are almost no barriers to fire, except for broad rivers, lakes and mountain crests. The forest fire fre quency index is high due to a predominance of light coniferous stands. A rapid spread of fires is also promoted by dry grass stands and fire-hazardous shrubs where the fire is spreading nearly as fast as the speed of wind. It was established that unmown mead ows, and abandoned pastures and croplands in the outskirts of villages present the threat of devastating fires not only in forests but also in settlements. In a situation, such as the one that arose in 2015, landscape fires turn to a natural disaster with severe forest-ecological consequences. Surviving forest stands decrease in productivity and increase in self-thinning, followed by an increasing degradation caused by subsequently recurring fires. Burns undergo local deforestation or a long-lasting replacement of coniferous stands by deciduous forests. The future runoff from the burned-over areas is able to enhance pollution of Lake Baikal. It is concluded that the EMERCOM resources used to fight the latest fires in Transbaikalia showed very little promise because of being delayed. A reasonable alternative to EMERCOM would involve advanced forecasting of high risks of fire oc currence in order to rapidly fight fires with moderate expenses without letting them turning to a natural disaster.

Аннотация: Wildfire disturbances effect changes in vegetation communities that in turn influence climate. Such changes in boreal forest ecosystems can persist over decadal time scales or longer. In the ecotone between boreal forest and steppe in the region southeast of Lake Baikal in southern Siberia, shifts between the two vegetation types may be precipitated by variations in site specific conditions, as well as disturbance characteristics such as fire frequency and severity. Warmer, drier conditions in the region have been associated with a decrease in fire return intervals and greater burn severity that may, in turn, drive conversion of forests to steppe vegetation at a greater rate than has occurred prior to the onset of warming and drying. Stand-replacing fires in Pinus sylvestris stands in southern Siberia may lead to recruitment failure postfire, particularly on southwest to west-facing slopes, which are more often dominated by grasses. This study uses a combination of field data and remotely sensed indices of vegetation and moisture to distinguish between recruitment pathways in southern Siberia, and to study the influence of factors related to soils, topography, fire severity and winter snow cover on these. We expected that recruitment success would be associated with lower burn severity (higher NBR), higher greenness (NDVI) and moisture (NDMI), and winter snow (NDSI) postfire. We also expected phenological characteristics to differ among recruitment paths. Prior to burning, our sites are broadly similar in terms of remotely sensed indices of moisture (NDMI), vegetation (NDVI), and winter fractional snow cover (NDSI), but recruitment failure sites are generally drier and less green postfire. Initial differences in greenness and moisture among sites characterized by abundant recruitment (AR), intermediate recruitment (IR) and recruitment failure (RF) become more pronounced over the initial decades postfire. The earliest separability of AR and RF sites using remotely sensed indices occurs in the winter months 3–4 years postfire, during which time NDSI is highest for AR sites and lowest for RF. Although seasonality was important with regard to distinguishing among AR, IR and RF index values, the timing of phenological events such as start and end of season did not differ significantly among the sites. © 2019 The Authors

Аннотация: The visibility of the spatial distribution of soil moisture is achieved through mapping, which is most simply carried out according to a digital model. Information on soil moisture is stored in the attribute table field of the Geographic Information System (GIS) layer and available for editing and later use. It is shown that a digital moisture model can be obtained through the cross-spectrum analysis of soil moisture with terrain parameters (frame of mapping - a digital elevation model) and ranking of forest types in order of increasing soil moisture (frame of mapping - a feature layer of inventory plots). The mapping results are demonstrated in terms of 2 test sites in mountainous and flat areas. Soil moisture mapping based on the DEM (digital elevation model) data was performed for a test site located in the Axial Western Sayan district of the mountain taiga forests; where forest types, due to the spatial cross-spectrum analysis, are distributed by terrain parameters and ranked by soil moisture. The result of the spatial analysis of the DEM is a raster (digital elevation model of soil moisture). Soil moisture mapping based on the forest management materials is performed for the test area representing the southern taiga forests of the Angara region. Ranking of soil moisture is made on the basis of inventory plot descriptions of the test site. The data of inventory plots was excluded from the analysis. Growth of tree species is a priori impossible down there (wetlands, rivers and lakes). In a simplified form, a ranked range of soil moisture is also demonstrated relative to the forest type as a generalized qualitative indicator of forest site conditions. Regardless of the land category (plantation, burnt area or cutover), each inventory plot receives an additional quantitative indicator of soil moisture, followed by the possibility of determining the regression equations for the potential productivity of tree species. It is found that in the presence of a feature layer of forest management data, soil moisture mapping is preferable to be adapted from the forest management materials. It is shown that there is a dependence of the productivity of stands on soil moisture.
