Аннотация: The drying of samples of mountain-meadow soils characterized by their permanently high moisture under natural conditions fundamentally changes the concentrations of the labile nitrogen and carbon compounds, as well as the patterns of their microbial transformation. When the soil samples are dried, a four- to fivefold increase in the content of the extractable organic nitrogen compounds, carbon compounds, and inorganic nitrogen compounds is observed, while the content of nitrogen and carbon of the microbial biomass decreases by two-three times. The rewetting of the dried soil launches the process of the replenishment of the nitrogen and carbon reserves in the microbial biomass. However, even after two weeks of incubation, their values were 1.5-2 times lower than the initial values typical of the natural soil. The restoration of the microbial community in the samples of the previously dried soils occurs in the absence of a deficiency of labile organic compounds and is accompanied by their active mineralization and the low uptake of ammonium nitrogen by the microorganisms.

Аннотация: Regional Siberian studies have already registered climate warming over the last several decades. We evaluated ongoing climate change in central Siberia between 1991 and 2010 and a baseline period, 1961-1990, and between 1991 and 2010 and Hadley 2020 climate change projections, represented by the moderate B1 and severe A2 scenarios. Our analysis showed that winters are already 2-3A degrees C warmer in the north and 1-2A degrees C warmer in the south by 2010. Summer temperatures increased by 1A degrees C in the north and by 1-2A degrees C in the south. Change in precipitation is more complicated, increasing on average 10% in middle latitudes and decreasing 10-20% in the south, promoting local drying in already dry landscapes. Hot spots of possible forest shifts are modeled using our Siberian bioclimatic vegetation model and mountain vegetation model with respect to climate anomalies observed pre-2010 and predicted 2020 Hadley scenarios. Forests are predicted to shift northwards along the central Siberian Plateau and upslope in both the northern and southern mountains. South of the central Siberian Plateau, steppe advancement is predicted that was previously non-existent north of 56A degrees N latitude. South of 56A degrees N, steppe expansion is predicted in the dry environments of Khakasiya and Tyva. In the southern mountains, it is predicted that the lower tree line will migrate upslope due to increased dryness in the intermontane Tyvan basins. The hot spots of vegetation change that are predicted by our models are confirmed by regional literature data.

Аннотация: The degree of aggregation of peat substrate and the size of structural elements can be used to distinguish between different stages of a peatland evolution and characterize relic features in the profile of modern peat soil. Carbon fractions separated from different aggregates are indicative of the age of peat accumulated in the period of active growth of the peatland and of the age of peat transformed during the peatland drying. On the basis of these data, annual rates of peat growth at different evolution stages can be determined, as well as the rates of organic carbon sequestration and the amount of peat forming from plant remains.

Аннотация: Structure of crown and viability of generative organs of Siberian fir were studied in disturbed forest ecosystems near Baikal Lake. The crown structure changes in damaged trees: a zone of subapical drying appears and apical dominance is lost. Needle chlorosis and necrosis appear and proceed in sprouts of male sexualization. The tree top including the female generative organs does not show degradation symptoms during about 30 years and produces seed cones. Processes of degradation in male generative zone greatly influence on fir tree pollen. Pollen viability of fir trees varied from year to year in different trees but always pollen quality of trees growing in the Khamar-Daban Mts in the air pollution zone was more poor in comparison with the pollen of trees at die Baikal Lake shore. Tree pollen growing in the Khamar-Daban Mts germinates in vitro but pollen tubes are formed short and not viable. Seed quality of fir trees is very low, A lot of seeds are sterile. Empty seeds prevail. The formation of empty seeds was caused by the low pollen germination in ovules and as a whole absence of pollen in ovules. The high sterility of generative organs and especially of Abies sibirica pollen can limit gametic selection and decrease fir diversity in forest ecosystems near Baikal Lake.

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: Energy and latent heat fluxes ?E were measured over ombrotrophic bogs in European Russia (Fyodorovskoye) and in central Siberia (Zotino) using the eddy covariance technique, as part of the EuroSiberian Carbonflux Project. The study covered most of the snowfree periods in 1998, 1999 and 2000; in addition some data were also collected under snow in early spring and late autumn 1999 and 2000. The snowfree period in Europian Russia exceeds the snowfree period in central Siberia by nearly 10 weeks. Marked seasonal and interannual differences in temperatures and precipitation, and hence energy partitioning, were observed at both sites. At both bogs latent heat fluxes (?E) exceeded sensible heat fluxes (H) during most of the snowfree period: maximum ?E were between 10 and 12 MJ m -2 d -1 while maximum H were between 3 and 5 MJ m -2 d -1. There was a tendency towards higher Bowen ratios at Fyodorovskoye. Net radiation was the most influential variable that regulated daily evaporation rates, with no obvious effects due to surface dryness during years with exceptionally dry summers. Total snowfree evaporation at Fyodorovskoye (320 mm) exceeded totals at Zotino (280 mm) by 15%. At the former site, evaporation was equal to or less than precipitation, contrasting the Zotino observations, where summer evaporation was distinctly higher than precipitation. During the entire observation period evaporation rates were less than 50% of their potential rate. These data suggest a strong 'mulching' effect of a rapidly drying peat surface on total evaporation, despite the substantial area of free water surfaces during parts of the year. This effect of surface dryness was also observed as close atmospheric coupling.

Аннотация: Seed productivity of the macrostrobile and seed quality in drying and healthy stands of the Abies slbirica growing in the mountains of the Southern Siberia - Khamar-Daban and Western and Eastern Sayany - were studied. It was established that under any growing conditions of fir, the seed productivity of its macrostrobile is very high, but the quality of the seeds produced is very low. In high mountains, where an intensive drying of fir forests takes place, seed sterilization increases. Most of the sterile seeds are hollow, which is connected with the low pollen quality. It is concluded that in Abies sibirica growing in the mountains of Southern Siberia, the reproductive potential of the species drops. It is assumed that formation of sterile seeds in a fir may cause the lack of forest-forming processes in fir forests. В© 1996 MAHK Hayka/Interperiodica Publishing.

Аннотация: The sulfur content in needles, the morphological structure of the crown, and the pollen quality of drying and healthy Siberian fir trees growing at different distances from the Baikal Integrated Pulp-and-Paper Mill were investigated. The highest content of sulfur in the needles was revealed in trees growing on the Khamar-Daban chain at height of 1100-1200 m a.s.1. It was determined that intensive fir forest decline, changes in the morphological structure of the crown, and the production of low quality pollen take place under the same conditions.

Аннотация: The reproductive sphere of the Siberian fir was studied in disturbed forest ecosystems near Lake Baikal. The crown morphostructure changes in damaged trees: a zone of subapical drying appears, apical dominance is lost, and the crown shape becomes weeping. Destructive processes appear and proceed in sprouts of male sexualization. It is proposed that the male reproductive sphere is highly susceptible to ecological stress.

Аннотация: Birch (Betula pendula Roth) growth within the Western Siberia forest-steppe was analyzed based on long-term (1897-2006) inventory data (height, diameter at breast height [dbh], and stand volume). Analysis of biometry parameters showed increased growth at the beginning of twenty-first century compared to similar stands (stands age = 40-60 years) at the end of nineteenth century. Mean height, dbh, and stem volume increased from 14 to 20 m, from 16 to 22 cm, and from ?63 to ?220 m3/ha, respectively. Significant correlations were found between the stands mean height, dbh, and volume on the one hand, and vegetation period length (rs = 0.71 to 0.74), atmospheric CO2 concentration (rs = 0.71 to 0.76), and drought index (Standardized Precipitation-Evapotranspiration Index, rs = -0.33 to -0.51) on the other hand. The results obtained have revealed apparent climate-induced impacts (e.g. increase of vegetation period length and birch habitat drying due to drought increase) on the stands growth. Along with this, a high correlation of birch biometric parameters and [CO2] in ambient air indicated an effect of CO2 fertilization. Meanwhile, further drought increase may switch birch stand growth into decline and greater mortality as has already been observed within the Trans-Baikal forest-steppe ecotone. © 2014 © 2014 Taylor & Francis.

Аннотация: Arctic ecosystems are warming rapidly, which is expected to promote soil organic matter (SOM) decomposition. In addition to the direct warming effect, decomposition can also be indirectly stimulated via increased plant productivity and plant-soil C allocation, and this so called "priming effect" might significantly alter the ecosystem C balance. In this study, we provide first mechanistic insights into the susceptibility of SOM decomposition in arctic permafrost soils to priming. By comparing 119 soils from four locations across the Siberian Arctic that cover all horizons of active layer and upper permafrost, we found that an increased availability of plant-derived organic C particularly stimulated decomposition in subsoil horizons where most of the arctic soil carbon is located. Considering the 1,035 Pg of arctic soil carbon, such an additional stimulation of decomposition beyond the direct temperature effect can accelerate net ecosystem C losses, and amplify the positive feedback to global warming.

Аннотация: The ecological features of microbial assemblages development in Central Evenkia forest soils (64 degrees 15'N, 100 degrees 13'E) were investigated on permanently installed sites on the right shore of river Kochechum on south- and north-exposition slopes, which differed in intensity of solar radiation, thickness of litter and seasonally thawed soil horison. We studied mineral soil layer 0-5 and 5-10 cm, including ground cover (moss and lichen sinusia). The structure of microbocenoses was examined by method of surface. inoculation on Petri dishes, microbial biomass and basal respiration by kinetic methods. According to the study conducted, oligotropic and copiotrophic group of microorganisms dominated in composition of microbocenoses in Central Evenkia cryogenic soils, what was due to the peculiarities of cryogenic soils of this region. Low soil temperatures, periodic soil overwetting and drying, slightly acid reaction of soil environment explained predominant development of bacteria in composition of microbial complexes (87-95%) in comparison with fungi. Our observations showed, that mineralisation processes proceeded more intensively in ground cover of moss sinusia in comparison with lichen sinusia, where the values of mineralisation coefficients were higher in the top mineral soil layers. Microbial biomass of examined cryogenic soils in natural conditions was concentrated mainly in litter subhorison in a moss and lichen sinusia. The analysis of microbial basal respiration revealed similar tendencies. The values of microbial metabolic coefficient revealed high disturbance ratio of ecological-trophic status of microbial communities, when only a small part of microbial pool is metabolically active.

Аннотация: This study aimed to better understand the stabilisation of rice rhizodeposition in paddy soil under the interactive effects of different N fertilisation and water regimes. We continuously labelled rice ('Zhongzao 39') with (CO2)-C-13 under a combination of different water regimes (alternating flooding-drying vs. continuous flooding) and N addition (250 mg N kg(-1) urea vs. no addition) and then followed C-13 incorporation into plant parts as well as soil fractions. N addition increased rice shoot biomass, rhizodeposition, and formation of C-13 (new plant-derived C) in the rhizosphere soils under both water regimes. By day 22, the interaction of alternating flooding-drying and N fertilisation significantly increased shoot and root C-13 allocations by 17 and 22%, respectively, over the continuous flooding condition. The interaction effect also led to a 46% higher C-13 allocation to the rhizosphere soil. Alone, alternating water management increased C-13 deposition by 43%. In contrast, N addition increased C-13 deposition in rhizosphere soil macroaggregates under both water regimes, but did not foster macroaggregation itself. N treatment also increased C-13 deposition and percentage in microaggregates and in the silt and clay-size fractions of the rhizosphere soil, a pattern that was higher under the alternating condition. Overall, our data indicated that combined N application and a flooding-drying treatment stabilised rhizodeposited C in soil more effectively than other tested conditions. Thus, they are desirable practices for improving rice cropping, capable of reducing cost, increasing water use efficiency, and raising C sequestration.

Аннотация: Concentrations of carbon and nitrogen extractable by 0.05 M K2SO4 (Cext and Next, respectively) in 14 soils of different ecosystems vary from 16 to 205 and from 4 to 53 mg/kg, respectively. The portion of Cext in soil organic matter is 0.06 to 0.38% of total carbon, and the portion of Next is 0.12–1.05% of total nitrogen. The storage of samples and their preparation to analysis differently affect the extractability of elements. The concentration of Cext is less variable than the concentration of Next. An increase in C extractability (by 1.4–6.7 times) is a common feature of all soils under drying; at the following incubation of dried soils, the extractability of C decreases by 28–56%. The extractability of N increases not only under drying (by 1.5–7.1 times) and the following incubation of samples (by 25–60% to 2–3 times), but also under freezing of most soils and at the incubation of fresh and defrozen samples. A close direct correlation is observed between the initial water content of soil and the relative increase in C extractability under drying and N extractability under freezing and drying. © 2017, Pleiades Publishing, Ltd.

Дана оценка динамики состояния лесов за последние десятилетия в полосе от непосредственной близости до 200 км и более от комбината. Анализ проведен с учетом ландшафтной структуры территории. Отмечено прогрессирующее с начала 80-х гг. усыхание больших массивов лесов. По литературным данным приводятся структура, динамика и распределение аэропромвыбросов предприятий Норильской горно-металлургической компании «Норильский никель», а по данным авторов рассматривается воздействие аэропромвыбросов Норильского промышленного района на лесные экосистемы Таймыра. Основное внимание уделено главной лесообразующей древесной породе - лиственнице сибирской Larix sibirica Ledeb. Отмечено полное отсутствие подроста лиственницы в зоне промышленного загрязнения. Изучение состояния техногенно поврежденных лесов проведено на основании дендрохронологических исследований в шести различных точках на разном расстоянии от г. Норильска, в основном южнее и восточнее металлургического комбината. Одна точка исследований (разреженное лиственничное сообщество) находится в 5 км северо-западнее Норильска. Исследовали насаждения разной степени поврежденности, в том числе полностью погибшие. Показано, что вне зоны влияния эмиссий НГМК не отмечено признаков повреждения листового аппарата деревьев, тогда как в зоне атмосферного загрязнения (оз. Хантайское) древостой в значительной степени пострадал. Главным повреждающим агентом служит двуокись серы.
In the study, based on the analysis of literary sources and the own research materials, the characteristic of the environmental situation in Taimyr is done, in connection with aerial technogenic impact of the Norilsk mining and metallurgical industrial complex. The dynamics of forest condition over the past decade in the area close to 200 km or more from the plant were evaluated. The analysis was performed taking into account the landscape structure of the territory. The progressive drying of the large areas of the northern forests since the early 80 is registered. In the article, according to the literature reviewed, the structure, dynamics and distribution of air industrial emissions of the Norilsk mining and metallurgical industrial complex «Norilsk Nickel» is analyzed and presented. Further, the authors considered the impact of air industrial emissions of Norilsk industrial region on the forest ecosystems of Taimyr. The focus is on the main forest-forming tree - Siberian larch Larix sibirica Ledeb. It is noted the complete absence of the larch undergrowth in the area of industrial pollution. Investigation of the technogenically damaged forests was carried out on the basis of dendrochronological research at six different points on different distances from the city of Norilsk, mainly to the south and east of the metallurgical plant. One study point (sparse larch community) is located 5 km north-west of Norilsk. We investigated stands of varying degrees of damage, including completely dead. It is shown, that outside the area of Norilsk mining and metallurgical industrial complex impact there were no signs of damage to the foliage of the trees and on the contrary, in the area of air pollution (Khantaiskoe Lake), forest stands are largely affected. The main damaging agent is sulfur dioxide.

Аннотация: Background and aims: Water and nutrient management influences the allocation and stabilisation of newly assimilated carbon (C) in paddy soils. This study aimed to determine the belowground allocation of C assimilated by rice and the subsequent C stabilisation in soil aggregates and as mineral-organic associates depending on combined alternate wetting and drying (AWD) versus continuous flooding (CF) and P fertilisation. Methods: We continuously labelled rice plants in 13CO2 atmosphere under AWD versus CF water management, and at two P fertilisation levels (0 or 80 mg P kg?1 soil). The 13C allocation to soil and its incorporation into the wet-sieved aggregate size classes and density fractions of the rhizosphere and bulk soils were analysed 6, 14, and 22 days after the labelling was started (D6, D14, and D22, respectively). Results: Under both water regimes and P fertilisation levels, the proportion of photoassimilates was the highest in the silt- and clay-size aggregate classes and in the mineral-associated fraction. On D6 and D14, P fertilization resulted in smaller 13C incorporation into soil, independent of water management. In the rhizosphere soil, at D22, P fertilisation increased 13C incorporation over no P amendment in macroaggregates (>250 ?m) by 32% (AWD) and 42% (CF), in microaggregates (250–53 ?m) by 97% (CF), and in the silt + clay size class (<53 ?m) by 83% (CF). Further, P fertilisation led to larger 13C incorporation into the rhizosphere soil light fraction (75% at AWD and 90% at CF) and dense fraction (38% and 45%, respectively), and into the bulk soil macroaggregates (71% and 78%, respectively). Conclusions: Phosphorus fertilisation increased the contents of recent photoassimilates in soil aggregate classes with longer residence time as well as of the particulate organic matter with the continuation of plant growth. This positive response of the stabilisation of recent plant photosynthates in soil to P fertilisation can increase the potential of paddy soil for C sequestration. This potential is not limited by the introduction of alternate wetting and drying water-saving technique. © 2018, Springer Nature Switzerland AG.

Аннотация: We used our database of tree biomass with a number of 433 sample trees of Larix from different ecoregions of Eurasia, involving 61 trees from Mongolia for developing an additive model of biomass tree components. Our approach solved the combined problem of additivity and regionality of the model. Our additive model of tree aboveground biomass was harmonized in two ways: first, it eliminated the internal contradictions of the component and of the total biomass equations, secondly, it took into account regional (and correspondingly species-specific) differences of trees in its component structure. A significant excess of larch biomass in the forest-tundra is found that may be explained by permafrost conditions, by tree growth in low-yielding stands with a high basic density of stem wood and relatively high developed tree crown in open stands. The aboveground biomass of larch trees in Mongolia does not stand out against the background of the most ecoregions of Eurasia. Based on our results, we conclude that the growing conditions of larch in Mongolia are not as tough as it was suggested earlier by other scientists. Biomass relations between regions may be explained by unknown and unaccounted factors and errors of measurements in all their phases (assessment of age, diameter, height of a tree, the selection of supposedly representative samples of component biomass, their drying, weighing, etc.). The question what explains the regional differences in the structure of biomass of trees with the same linear dimensions of their stems, remains open. Undoubtedly, the differences in tree age here play an important role. Also, important factor is the variation in the morphological structure of stands, which, in turn, is determined by both climatic and edaphic factors. The obtained models allow the determination of larch forest biomass in different ecoregions of Eurasia with the help of height and diameter data. © 2019, Lomonosov Moscow State University.

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

This study aimed to determine the belowground allocation of C assimilated by rice and the subsequent C stabilisation in soil aggregates and as mineral-organic associates depending on combined alternate wetting and drying (AWD) versus continuous flooding (CF) and P fertilisation.
