Аннотация: Using light aircraft and at intervals of approximately 14 days, vertical profiles of temperature, humidity, CO2 concentration and C-13/C-12 and O-18/O-16 ratio, as well as concentrations of CH4, CO, H-2 and N2O, from about 80 to 3000 m above ground level have been determined for the atmosphere above a flux measurement tower located near the village of Zotino in central Siberia (60degrees45'N, 89degrees23'E). As well as being determined from flask measurements (typically at heights of 100, 500, 1000, 1500, 2000, 2500 and 3000 m) continuous CO2 concentration profiles at 1 Hz have also been obtained using an infrared gas analyser. This measurement program is ongoing and has been in existence since July 1998. Data to November 2000 are presented and show a seasonal cycle for CO2 concentration of about 25 mumol mol(-1) within the atmospheric boundary layer (ABL) and about 15 mumol mol(-1) in the free troposphere. Marked seasonal cycles in the isotopic compositions Of CO2 are also observed, with that of oxygen-18 in CO2 being unusual: always being depleted in the ABL with respect to the free troposphere above. This is irrespective of whether the CO2 concentration is higher or lower in the free troposphere. We interpret this as indicating a net negative discrimination being associated with the net terrestrial carbon exchange, irrespective of whether photosynthesis or respiration dominates the net carbon flux in this region. During winter flights, large fluctuations in CO2 concentration with height are often observed both within and above the stable ABL. Usually (but not always) these variations in CO2 concentrations are associated with more or less stoichiometrically constant variations in CO and CH4 concentrations. We interpret this as reflecting the frequent transport of polluted air from Europe with very little vertical mixing having occurred, despite the large horizontal distances traversed. This notion is supported by back-trajectory analyses. Vertical profiles Of CO2 concentration with supplementary flask measurements allow more information on the structure and composition of an air mass to be obtained than is the case for flask measurements or for ground-based measurements only. In particular, our data question the notion that there is usually anything like "well mixed background air" in the mid-to-high northern latitudes during the winter months.

Аннотация: Estimating terrestrial ecosystem CO2 fluxes is very important for our understanding of the global carbon cycle. This paper presents a zero-dimensional mathematical model of the ecosystem of Siberian boreal forests. It was used for comparison tall-tower-based CO2 fluxes with biometric field measurements. The model is a system of ordinary differential equations with additional conditions superimposed on the parameters. The main occurring proceses.are described - photosynthesis, respiration, seasonal changes of active phytomass, water balance of trees, the influence of light, humidity, and temperature of phytosynthesis and respiration.

Аннотация: The analysis of soil-climatic relationships was performed on the basis of the BIOME database on climate and vegetation created by the V.N. Sukachev Institute of Forestry (Siberian Branch of the Russian Academy of Sciences) and the Soil Map of the Russian Federation (1: 2.5 M scale) for the southern part of the boreal zone of Siberia. Climatic parameters (accumulated daily temperatures above 10A degrees C, continentality of the climate, and humidity of the climate) specifying the development of major types of mesomorphic soils on this territory were determined. The climatic contacts between different soil groups were established. The soil diversity in climatic ecotones was characterized. The criteria of steady and unsteady position of soils in the space of climatic coordinates were analyzed, and the measure of the climatic sensitivity of soils was suggested.

Аннотация: [1] Twenty tree ring C-13/C-12 ratio chronologies from Pinus sylvestris (Scots pine) trees were determined from five locations sampled along the Yenisei River, spaced over a total distance of similar to1000 km between the cities of Turuhansk (66degreesN) and Krasnoyarsk (56degreesN). The transect covered the major part of the natural distribution of Scots pine in the region with median growing season temperatures and precipitation varying from 12.2degreesC and 218 mm to 14.0degreesC and 278 mm for Turuhansk and Krasnoyarsk, respectively. A key focus of the study was to investigate the effects of variations in temperature, precipitation, and atmospheric CO2 concentration on long-and short-term variation in photosynthetic C-13 discrimination during photosynthesis and the marginal cost of tree water use, as reflected in the differences in the historical records of the C-13/C-12 ratio in wood cellulose compared to that of the atmosphere (Delta(13)C(c)). In 17 of the 20 samples, trees Delta(13)C(c) has declined during the last 150 years, particularly so during the second half of the twentieth century. Using a model of stomatal behaviour combined with a process-based photosynthesis model, we deduce that this trend indicates a long-term decrease in canopy stomatal conductance, probably in response to increasing atmospheric CO2 concentrations. This response being observed for most trees along the transect is suggestive of widespread decreases in Delta(13)C(c) and increased water use efficiency for Scots pine in central Siberia over the last century. Overlying short-term variations in Delta(13)C(c) were also accounted for by the model and were related to variations in growing season soil water deficit and atmospheric humidity.

Аннотация: Natural colonization of the steppe by forest vegetation is often observed in the contact zone between forest and steppe communities in northern Mongolia. Such successions appear owing to cyclic changes in the climate humidity. It was shown that morphological features of noncalcareous chernozems and their dynamic properties (pH, total exchangeable cations, humus composition) change under the influence of forest vegetation. These changes, however, are insufficient for attributing such chernozems to a new category.

Аннотация: A system of zonality in Siberia has been formed under the control of continentality, which provides the heat and humidity regimes of the forest provinces. Three sectors of continentality and four to six boreal subzones form a framework for the systematisation of the different features of land cover in Siberia. Their climatic ordination provides the fundamental basis for the principal potential forest types (composition, productivity) forecasting the current climate. These are useful in predicting the future transformations and successions under global changes.

Аннотация: The general potential, exchange, and actual (pH) acidities were investigated in the litter of the succession row of swamp birch woods. Their variabilities constitute, respectively, 75.9-174.4, 3.7-25.8 mmol (+)/100 g of the sampling, 3.7-5.5. For the first time, using the methods of geostatistics, their spatial variability was analyzed and the contributions of the trend, autocorrelation component, and the radius of the spatial correlation were estimated. It was established that in combination with the woody plants detritus, which is uniformly distributed along the ecological profile, the specific composition of the grass-moss tier, which corresponds to the humidity of edaphon, forms the picture of the spatial structure of acid properties of the litter. It was noted that the prime cause of variability consists in the particularities of the water regime of the habitats of swamp birch woods.

Аннотация: The aim of this work is an analysis of the causes of spruce (Picea abies L.) decline and mortality in Belarus. The analysis was based on forest inventory and Landsat satellite (land cover classification, climate variables (air temperature, precipitation, evaporation, vapor pressure deficit, SPEI drought index)), and GRACE-derived soil moisture estimation (equivalent of water thickness anomalies, EWTA). We found a difference in spatial patterns between dead stands and all stands (i.e., before mortality). Dead stands were located preferentially on relief features with higher water stress risk (i.e., higher elevations, steeper slopes, south and southwestern exposure). Spruce mortality followed a series of repeated droughts between 1990 and 2010. Mortality was negatively correlated with air humidity (r = -0.52), and precipitation (r = -0.57), and positively correlated with the prior year vapor pressure deficit (r = 0.47), and drought increase (r = 0.57). Mortality increased with the increase in occurrence of spring frosts (r = 0.5), and decreased with an increase in winter cloud cover (r = -0.37). Spruce mortality was negatively correlated with snow water accumulation (r = -0.81) and previous year anomalies in water soil content (r = -0.8). Weakened by water stress, spruce stands were attacked by pests and phytopathogens. Overall, spruce mortality in Belarussian forests was caused by drought episodes and drought increase in synergy with pest and phytopathogen attacks. Vast Picea abies mortality in Belarus and adjacent areas of Russia and Eastern Europe is a result of low adaptation of that species to increased drought. This indicates the necessity of spruce replacement by drought-tolerant indigenous (e.g., Pinus sylvestris, Querqus robur) or introduced (e.g., Larix sp. or Pseudotsuga menzieslii) species to obtain sustainable forest growth management.

Аннотация: The decline of spruce stands in Belarus has been analyzed in relation to the dynamics of climatic variables. The results show that this process is correlated with the amount of precipitation, moisture deficit, index of aridity, relative air humidity, and evapotranspiration. Frosts at the onset of the growing season enhance tree die-off, while increase in cloud cover has a favorable effect on the state of spruce stands. Damage to trees occurs mainly in areas with elevated and convex topography and slopes of southwestern aspect, increasing on steeper slopes. The level of die-off is most closely correlated with conditions of the previous year, which is explained by the impact of biological factors (pest insects and phytopathogens) on tree stands already affected by water stress. The decline of spruce stands on a mass scale is also observed in neighboring regions of Russia and counties of East Europe, which is evidence for a low adaptability of spruce to current climate change, including the increasing frequency and severity of dry periods. © 2016, Pleiades Publishing, Ltd.

Аннотация: We aim to achieve a mechanistic understanding of the eco-physiological processes in Larix decidua and Pinus mugo var. uncinata growing on north- and south-facing aspects in the Swiss National Park in order to distinguish the short- and long-term effects of a changing climate. To strengthen the interpretation of the delta O-18 signal in tree rings and its coherence with the main factors and processes driving evaporative-delta O-18 needle water enrichment, we analyzed the delta O-18 in needle, xylem and soil water over the growing season in 2013 and applied the mechanistic Craig-Gordon model (1965) for the short-term responses. We found that delta O-18 needle water strongly reflected the variability of relative humidity mainly for larch, while only delta O-18 in pine xylem water showed a strong link to delta O-18 in precipitation. Larger differences in offsets between modeled and measured delta O-18 needle water for both species from the south-facing aspects were detected, which could be explained by the high transpiration rates. Different soil water and needle water responses for the two species indicate different water-use strategies, further modulated by the site conditions. To reveal the long-term physiological response of the studied trees to recent and past climate changes, we analyzed delta C-13 and delta O-18 in wood chronologies from 1900 to 2013. Summer temperatures as well as summer and annual amount of precipitations are important factors for growth of both studied species from both aspects. However, mountain pine trees reduced sensitivity to temperature changes, while precipitation changes come to play an important role for the period from 1980 to 2013. Intrinsic water-use efficiency (WUEi) calculated for larch trees since the 1990s reached a saturation point at elevated CO2. Divergent trends between pine WUEi and delta O-18 are most likely indicative of a decline of mountain pine trees and are also reflected in decoupling mechanisms in the isotope signals between needles and tree-rings.

Аннотация: Many soil functions are modulated by processes at soil biogeochemical interfaces (BGIs). However, characterizing the elemental dynamics at BGIs is hampered by the heterogeneity of soil microenvironments. In order to investigate the processes of BGI formation in an upland soil (Mollisol) and a paddy soil (Oxisol), we developed a SoilChip method by assembling dispersed soil particles onto homogeneous 800-?m-diameter microarray chips and then submerging them in a solution that contained dissolved organic matter (OM) extracted from one of the two soils. The chips with Mollisol particles were incubated at 95–100% humidity, whereas the chips with Oxisol particles were incubated at 100% humidity. Dynamics of individual elements at the soils’ BGIs were quantitatively determined using X-ray photoelectron spectroscopy (XPS). Distinct differences in the soil-microbe complexes and elemental dynamics between the Mollisol and Oxisol BGIs suggested that the formation of specific BGIs resulted from the complex interaction of physical, chemical, and microbial processes. By integrating the SoilChip and XPS, it was possible to elucidate the dynamic formation of the two different soil BGIs under standardized conditions. Therefore, the SoilChip method is a promising tool for investigating micro-ecological processes in soil. © 2017

Аннотация: The ground and excited states of the pheromone molecules produced by xylophagous insects (the bark beetle Ips typographus L., the black fir sawyer beetle Monochamus urussovi Fisch., and the black pine sawyer M. galloprovincialis Oliv.) were modeled using a quantum chemical method utilizing DFT (density functional theory) with the B3LYP functional. The absorption wavelengths (energies) and dipole moments were calculated; the transitions of electrons from occupied to empty molecular orbitals were considered. The computed data were used to assess the stability of pheromone molecules exposed to environmental factors, such as solar radiation and humidity. © 2017, Pleiades Publishing, Inc.

Аннотация: Climate changes have induced the northward migration of outbreaks of the Siberian silk moth (Dendrolimus sibiricus Tschetv.), one of the most dangerous pests in the taiga. The initial outbreak of the Siberian silk moth began in 2014 in Siberian pine.fir stands within the Yenisei Plain on the southwestern flat slopes at elevations up to 200 m above sea level. Further, the outbreak extended to the parts of the forest with higher humidity, the northern slopes, and Yenisei Ridge at low and middle elevations. The northern limit of the outbreak zone shifted to 50 km (to 60A degrees 26' N) northward from the historical boundary of formerly observed outbreaks. The outbreak was incited by an increase in aridity, the sum of positive temperatures (t > +10A degrees C), and a decrease in soil moisture. It extended to an area of 800000 ha. Stand mortality was accompanied by the activation of secondary pests, including aggressive bark beetle species Polygraphus proximus. The outbreak under study is part of the panzonal outbreak that occurred in 2014-2017 on the territory of Siberia in Krasnoyarsk krai and Tomsk, Kemerovo, and Irkutsk oblasts. The increase in warming, aridity, and vegetative period provides opportunities for the Siberian silk moth to migrate to the northern dark-conifer taiga.

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: 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: Анализировались индекс радиального прироста (ИП) Abies sibirica Ledeb. и динамика массового усыхания пихтовых древостоев в горных лесах Восточного Саяна (заповедник “Столбы”). Беспрецедентное по масштабам усыхание пихты оказалось спровоцировано водным стрессом, обусловленным возрастанием температуры воздуха, в синергизме с воздействием уссурийского полиграфа ( Polygraphus proximus Blandford), ксилофага, ранее не наблюдавшегося в ареале Abies sibirica . В начальной фазе потепления климата наблюдалось возрастание ИП, сменившееся его депрессией в 1985-2017 гг. Усыханию пихтарников предшествовало усиление зависимости ИП от индекса сухости SPEI и влажности корнеобитаемого слоя (ВКС). При этом ИП когорты усохших деревьев сильнее зависел от ВКС ( r ² = 0,56) и SPEI ( r ² = 0,74), чем ИП когорты выживших деревьев ( r ² = 0,15 и r ² = 0,39 соответственно). Усыхание пихты началось в 2000-х гг., когда ослабленные водным стрессом пихтарники подверглись атаке уссурийского полиграфа. В этот период погибшие древостои локализовались преимущественно на элементах рельефа с наибольшей вероятностью водного стресса (крутые склоны, расположенные в “дождевой тени”). К 2017 г. усыхание распространилось на всю территорию пихтарников, что привело к гибели ~75 % древостоев. В данный период наблюдалась тесная связь ИП со смертностью деревьев пихты ( r = -0,79). Выжившие деревья по сравнению с усохшими произрастали в условиях более высокой влажности корнеобитаемой зоны. Примечательна близость траекторий ИП когорт усохших и живых деревьев, что указывает на вероятность гибели живых деревьев в условиях прогнозируемого возрастания засушливости климата.
In the initial phase of climate warming, an increase in radial increment was observed, which was replaced by a depression in 1985-2017. The declining of fir trees was preceded by an increase in the relationship between growth index and SPEI, also between growth index and root zone moisture content. At the same time, growth index of the declining cohort was more closely associated with root zone moisture content ( r² = 0.56) and SPEI ( r ² = 0.74) than growth index of the surviving cohort ( r ² = 0.15 and r ² = 0.39, respectively). Fir declining began in the 2000s, when Abies sibirica trees, weakened by water stress, were attacked by Polygraphus proximus Blandford. During this period, dead stands were localized mainly on the relief elements with the highest probability of water stress (steep slopes located in “rain shadow”). By 2017, the declining spread throughout the entire territory of fir stands, which led to the mortality of ~75 % of fir stands. During the period of tree declining, a close relationship was observed between growth index and fir mortality ( r = -0.79). The surviving trees grew in conditions of a higher humidity of root zone (compared to declining trees). Noteworthy is the proximity of growth index trajectories of cohorts of declining and surviving trees, which indicates the probability of mortality of surviving trees in the context of a predicted climate aridity increase.

Аннотация: The radial increment of Abies sibirica Ledeb. and mortality dynamics of fir stands in the mountain forests of the Eastern Sayan (Stolby State Nature Reserve) have been analyzed. The unprecedented decline in fir stands is caused by water stress due to an increase in air temperature and synergy with the impact of the Polygraphus proximus Blandford. This xylophage was not previously observed in the Abies sibirica range. In the initial phase of climate warming, an increase in radial increment was observed, which was replaced by a depression in 1985-2017. The declining of fir trees was preceded by an increase in the relationship between growth index and SPEI, as well as between the growth index and root-zone moisture content. At the same time, the growth index of the declining cohort was more closely associated with the root zone moisture content (r(2) = 0.56) and SPEI (r(2) = 0.74) than the growth index of the surviving cohort (r(2) = 0.15 and r(2) = 0.39, respectively). The decline in fir began in the 2000s, when Polygraphus proximus Blandford attacked trees Abies sibirica. During this period, dead stands were localized mainly on the relief elements with the highest probability of water stress (steep slopes located in a "rain shadow"). By 2017, the decline spread throughout the entire territory of fir stands, which led to the mortality of similar to 75% of fir stands. During the period of tree decline, a close relationship was observed between growth index and fir mortality (r = -0.79). The surviving trees grew under conditions of a higher root-zone humidity (compared to declining trees). The proximity of growth-index trajectories of cohorts of declining and surviving trees, which indicates the probability of mortality of surviving trees in the context of a predicted climate aridity increase, is noteworthy.
