Аннотация: The Trans-Baikal (or Zabailkal'e) region includes the forest-steppe ecotones south and east of Lake Baikal in Russia and has experienced drought for several years. The decline and mortality of birch (Betula pendula) stands within the forest-steppe ecotone Trans-Baikal region was studied based on a temporal series of satellite data, ground measurements, and tree ring analysis. During the first decade of the 21st century birch stands decline and mortality were observed on about 5% of the total area of stands within our 1250 km(2) study area. Birch forest decline and mortality occurs mainly at the margins of stands, within the forest-steppe ecotone on slopes with direct insolation. During the first decade of the 21st century summer (June-August) precipitation was about 25% below normal. Soil water content measurements were lowest within dead stands and highest within healthy stands and intermediate within damaged stands. Drought impact on stands was amplified by an increase in summer air temperatures (+0.9 degrees C) in comparison with the previous decade. Tree ring data of "surviving" and "dead" tree groups showed a positive correlation with summer/annual precipitation and negative correlation with summer air temperatures. Temperature and precipitation extreme anomalies tend to occur in the region with a period of about 27 years. The observed anomaly was the most severe since the beginning of meteorological observations in the year 1900. Data for the other sites showed a positive climate impact on the growth and expansion of Siberian forests. That is, the same species (B. pendula) showed considerable increase (1.4 times both in height and stem volume) during 20th-21st centuries as temperature increased but precipitation remained at adequate levels.

Аннотация: Changes in the composition of microbial complexes and their biochemical activity in soil in the vicinity of a strong source of HF emission have been studied. A sharp decrease of the biomass, the number of asporous bacteria and actinomycetes, and a smaller decrease of the number of microscopic fungi has been revealed, along with a decrease in the enzymatic and respiratory activity of contaminated soil with the relative increase in the fraction of sporiferous bacteria. On the basis of the response of introduced population of Bacillus subtilis to different doses of HF, NaF, Na(2)SO(3) microbiological norm-fixing for technogenic soil ecosystems has been carried out.

Аннотация: The postfire transformation of the functional activity of the microbial cenoses and the main soil properties under mixed larch forests were studied in the lower reaches of the Angara River. It was shown that the intensity of the postfire changes in the population density, biomass, and activity of the microorganisms in the dark podzolized brown forest soil depended on the degree of burning of the ground cover and the surface litter during the fire. The maximum effects of the fire on the microbial cenoses were observed in the litter and the upper 5-cm-thick layer of the dark-humus horizon in the areas of intense burning. The postfire restoration of the structural-functional activity of the microbial cenoses was determined by the degree of transformation of soil properties and by the postpyrogenic succession in the ground cover. The microbial complexes of the dark podzolized brown forest soils under mixed larch forests in the studied region restored their functional activity after the fires of different intensities quicker than the microbial cenoses of the sandy podzols in the pyrogenic lichen-green-moss pine forests of the same zone.

Аннотация: We studied post-fire transformations in functional characteristics of soil microbial communities and invertebrate complexes in the central-taiga pine forests of Central Siberia. The study revealed that fires of any severity reduce the density and diversity of soil invertebrates and adversely affect the structure and functioning of the sandy podzol microbial complexes. Post-fire recovery of the density and structure of soil invertebrate complexes and the functioning of sandy podzol microbial communities depend on fire duration and severity, as well as dynamics of hydrothermal and trophic properties of the pine forest soils.

Аннотация: 1] There were large interannual variations in burned area in the boreal region ( ranging between 3.0 and 23.6 x 10 6 ha yr(-1)) for the period of 1992 and 1995-2003 which resulted in corresponding variations in total carbon and carbon monoxide emissions. We estimated a range of carbon emissions based on different assumptions on the depth of burning because of uncertainties associated with the burning of surface-layer organic matter commonly found in boreal forest and peatlands, and average total carbon emissions were 106-209 Tg yr(-1) and CO emissions were 330-77 Tg CO yr(-1). Burning of ground-layer organic matter contributed between 46 and 72% of all emissions in a given year. CO residuals calculated from surface mixing ratios in the high Northern Hemisphere ( HNH) region were correlated to seasonal boreal fire emissions in 8 out of 10 years. On an interannual basis, variations in area burned explained 49% of the variations in HNH CO, while variations in boreal fire emissions explained 85%, supporting the hypotheses that variations in fuels and fire severity are important in estimating emissions. Average annual HNH CO increased by an average of 7.1 ppb yr(-1) between 2000 and 2003 during a period when boreal fire emissions were 26 to 68 Tg CO(-1) higher than during the early to mid-1990s, indicating that recent increases in boreal fires are influencing atmospheric CO in the Northern Hemisphere.

Аннотация: Advanced Very High Resolution Radiometer (AVHRR) data are used to produce an active-fire detection product for the fire season in 1999 and 2000 and an area burned product for 1996-2000. The distribution of fire is presented ranging from the Urals in the west to the eastern coast and from the semi-dry steppe regions in the south through the taiga in the north. A temporal and spatial pattern of fire is observed migrating from north of 40degrees N latitude in April to north of 60degrees N by mid-July. Fire is widespread in August, spanning the entire geographic range. In contrast to these patterns, no similar east-west migrations are discernible from these data. Peak active-fire counts are detected in early May between 50 and 55degrees N latitude in both 1999 and 2000. Wildfire in Russia is highly variable, both annually and interannually, with differences in reported area burned ranging from 0.234 to 13.3 million hectares per year. Comparing Russian fire statistics to satellite-based data from this investigation and previous works, we find area burned in Russia may be commonly underestimated by an average of 213%. Underestimates of this magnitude could strongly affect emissions estimates and climate change research.

Аннотация: Spatial distributions of root systems of Larix gmelinii (Rupr.) Rupr. trees were examined in two stands in central Siberia: an even-aged stand (ca. 100 yrs-old) and a mature, uneven-aged (240-280 yrs-old) stand. Five larch trees of different sizes were sampled by excavating coarse roots (diameter > 5 mm) in each stand. Dimensions and ages of all first-order lateral roots were measured. Micro-scale conditions of soil temperature and soil water suction ( each 10 cm deep) were also examined in relation to earth hummock topography (mound vs. trough) and/or ground floor vegetation types (moss vs. lichens). All larch trees developed superficial root systems, consisting of the aborted short tap root (10-40 cm in soil depth) and some well-spread lateral roots (n = 4-13). The root network of each tree was asymmetric, and its rooting area reached about four times the crown projection area. Lateral roots generally expanded into the upper soil layers of the mounds where summer soil temperature was 1-6degreesC higher than inside nearby troughs. Chronological analysis indicated that lateral root expansion started successively from lower to upper parts of each aborted tap root, and some lateral roots occurred simultaneously at several decades after tree establishment. The process of root system development was likely to be primarily linked with post-fire dynamics of rhizosphere environment of the permafrost soils.

Аннотация: Reconstruction of the size distribution of trees in stands provides critical information for assessing the effects of environmental changes on forests and for forest management. For furthering a method of such reconstruction, feasibility of estimating size distribution in stem volume from measurement of the largest trees was examined for even-aged pure stands of Pinus banksiana Lamb.and Larix gmelinii (Rupr.) Rupr. We tested what percentage of the largest trees should be included in obtaining a frequency distribution in stem volume that is not statistically different from the observed size distribution patterns. The -3/2 power, beta-type, and adjusted beta-type distribution functions were applied. Comparison of the observed stem frequencies and those estimated from measurement of the largest trees in a stand suggested that (i) the -3/2 power distribution, beta-type distribution, or adjusted beta-type distribution may be used for reconstruction of stem size variation in pure stands, if the overall size variation could be approximated by one of these functions; (ii) we can be at least 95% sure that the tree size pattern be expressed successfully with the -3/2 power distribution with tree samples of only the largest 20% in the stand, or with the beta-type distribution with the largest 30% in the stand; and (iii) the reliability decreases somewhat for the adjusted beta-type distribution. The second observation implies that reconstruction of the temporal changes in stand structure may be reliable up to the time when the stand density was about five times that of the trees used for fitting the -3/2 power distribution curve. Reliability may be warranted up to the stand density of about three times as the number of trees used for fitting the beta-type distribution. Other considerations and limitations are also discussed.

Аннотация: A method was proposed for quantitatively reconstructing structural development over time of even-aged monospecific forests and was applied to a larch (Larix gmelinii (Rupr.) Rupr.) stand in Siberia. It relies on samples obtained at one-time observation and some simple assumptions considered general in even-aged stands. Tree-ring data taken from breast height of a group of the largest trees and those measured at various stem heights of several individuals representing the range of tree sizes in the plot are used for the estimation. Stand density and parameters of stem volume distribution at a given time in the past were calculated with the "stem slenderness index," and with an assumption of the -3/2 power distribution for the distribution function of stem size, respectively. By developing time-dependent allometric relationships for individual tree attributes, the whole-stand values of stem volume and its increment were reconstructed for several decades of stand development. Estimated history of the changes in stand density, total stem volume, and stem volume growth for the dense larch stand examined, mostly agreed with a separate estimation by the self-thinning assumption.

Аннотация: Most of the research about the effects of the release of carbon and other chemicals to the atmosphere during forest fir es focuses on emissions from crown fires or slash fires in which a high percentage of the fine fuels are burned However, in many temper-ate and boreal conifer ecosystems, surface fires of varying intensities and severities are an important part of the fire regime. In Russia a large percentage of the area burned in a typical year is in surface fires, which will result in lower carbon emissions than crown fires because of lower fuel consumption. lit Russian boreal for est, different distribution patterns of fire severity across the landscape could produce fourfold differences in carbon release. Furthermore, tree mortality after surface fires is often quite extensive, leading to a pulse in carbon release as needles and other fine fuels fall to the ground and decompose. With extensive tree mortality a decrease in carbon sequestration is expected for several years, until stand level photosynthesis returns to prefire levels. Perhaps the largest potential source of error in estimates of carbon release from biomass fires in Russia is inaccuracy in estimates of burned area. Many published estimates of annual burned area in Russia may be extremely low. On the basis of information on fire return intervals and area of boreal forest, 12 million ha per year may be a reasonable conservative estimate of burned area until better data are available. Based on this estimate, direct and indirect fire-generated carbon emissions from boreal forests worldwide may exceed 20% of the estimated global emissions from biomass burning, making them an important component in understanding global atmospheric chemistry. In considering effects of fire an global atmospheric chemistry, it is important to include the effects of fire severity, postfire mortality, decomposition of fine fuels, and changing postfire vegetation structure as components of fire-induced changes in ecosystem-level carbon flux. But the most important factor may be accurate information on the annual area burned. Levels of carbon storage are likely to be highly sensitive to changes in fire return intervals that result from direct human activities and from climatic changes, making accurate assessments of burned areas and fire severity critical. Strong fire management programs will be key to managing future fire regimes and carbon cycling in Russia's boreal forest. Published by Elsevier Science Ltd.

Аннотация: The number and the biomass of microorganisms were determined in the soils of the floodplain and islands in the Selenga River delta. The population of fungi in the soils studied was low. The number of saprotrophic prokaryote microorganisms varied from 10(6)-10(8) CFU/g of soil in the upper horizons to 10(4)-10(5) CFU/g in the lower horizons of the soils. This pattern is typical for most zonal soils. The microbial biomass in the floodplain soils was 2-4 times as high as that in the soils of the islands. The number of microorganisms of different ecologic-trophic groups participating in the nitrogen and carbon mobilization was much lower than that in the hydromorphic soils of the Transbaikal region or in the cryogenic soils of the Angara River basin (Irkutsk district). The low coefficient of microbiological mineralization and the low coefficient showing the lack of nitrogen (coefficient of oligotrophness) in the soils indicated the weak processes of organic matter decomposition in the soils studied. During the season investigated (August-September), the bacterial complexes in all the soils were dominated by bacteria of the genera Bacillus, Pseudomonas, and Aquaspirillum. In the floodplain soils, streptomycetes constituted a considerable part of the microbial complexes of the floodplain soils, whereas, in the soils of the islands, their number was minor.

Аннотация: One of the most common descriptors of the relationship between root and shoot biomass is the root : shoot ratio, which has become a core method for estimating root biomass from the more easily measured shoot biomass. Previous reviews have examined root : shoot ratio data, but have only considered particular vegetation types and have not always critically reviewed the data used. Reliable root : shoot ratios are needed for a wide range of vegetation types in order to improve the accuracy of root biomass estimates, including those required for estimating the effects of land management and land use change in National Greenhouse Gas Inventories. This study reviewed root : shoot ratios in terrestrial biomes. A key facet of our analysis was a critical methodological review, through which unreliable data were identified and omitted on the basis of specific criteria. Of the 786 root : shoot ratio observations collated, 62% were omitted because of inadequate or unverifiable root sampling methods. When only the reliable data were examined, root : shoot ratios were found to be negatively related to shoot biomass, mean annual precipitation, mean annual temperature, forest stand age, and forest stand height. Although a single allometric equation derived in this study reliably predicted root biomass from shoot biomass for forests and woodlands, in general, the use of vegetation-specific root : shoot ratios were found to be a more accurate method for predicting root biomass. When the root : shoot ratio data collated here were applied to an analysis of the global carbon budget, there was a 50% increase in estimated global root carbon stock, and a 12% increase in estimated total carbon stock of terrestrial vegetation. The use of the vegetation-specific root : shoot ratios presented in this study is likely to substantially improve the accuracy of root biomass estimates for purposes such as carbon accounting and for studies of ecosystem dynamics.

Аннотация: The state of microbial cenoses in the soils of forest ecosystems damaged by fires of different strengths and gypsy moth outbreaks (Central Siberia) was assessed by the intensity of the basal respiration, the content of carbon of the microbial biomass, and the microbial metabolic quotient. The degree of the disturbance of the microbial cenoses in the soils under pine forests after fires was higher than that in the soils under the forests defoliated by gypsy moths. The greatest changes of the microbial complexes were recorded after the fires of high and medium intensity. In the litters, the content of the microbial biomass, the intensity of basal respiration, and the microbial metabolic quotient value were restored on the fifth year after the fires, whereas in the upper (0-10 cm) soil layer, these parameters still differed from those in the control variant, especially after the highly intense fires. After the weak fires, the ecophysiological state of the microbial complexes was restored within two-three years.

Аннотация: Approximately 20 experimental fires were conducted on forest plots of 1-4 ha each in 2000-07 in two types of boreal forests in central Siberia, and 18 on 6 x 12-m plots in 2008-10. These experiments were designed to mimic wildfires under similar burning conditions. The fires were conducted in prescribed conditions including full documentation on pre-fire weather, pre-fire and post-fire forest fuels, fire intensities, and other biological, physical and chemical parameters. The amount of particulate matter emitted during a typical fire averaged 0.6 t ha(-1) and ranged within 0.2-1.0 t ha(-1) depending on burning conditions. Particulates accounted for similar to 1-7% of the total mass of the consumed biomass during a typical forest fire (10-30 t ha(-1) based on our data from 2000-07). Most of the particulate matter consists of organic substances, 77% on average, with a range of 70-90%. Elemental carbon averaged 8%, with a range of 2-18%. Trace element compositions and amounts of particulates indicate that there was no actual difference in the element emissions sampled from the fires conducted in the two forest types (6-8% in larch forest and 8% in pine forest). Most of the particulate matter, 90-95%, consists of submicrometre and near-micrometre particles similar to 0.1-5 mu m in diameter.

Аннотация: The phospholipid fatty acid (PLFA) composition of microorganisms in podzolic soils of pine forests was studied in Central Siberia. The live microbial biomass in the 1-m mineral soil layer was found to gradually decrease with depth. Although the biomass decreased by half in the lower horizons, its content remained sufficiently high (12-14 nmol FAs/g soil). The coefficient of similarity in the fatty acid composition between the soils of forest and open (unforested) sites was 0.85. The coefficient of fatty acid richness in the mineral soil layer decreased with depth, while differences in fatty acid profiles increased.

Аннотация: Microbial respiration and biomass were evaluated in soils of the Ermak Tree Nursery and Pogorel'skii Forest under different coniferous species. The degree of disturbance of each biocenosis was determined from the metabolic coefficient (qCO(2)). The microbial investigation demonstrated a lower resistance to ecological factors of the tree nursery biocenosis as compared to those of the Pogorel'skii Forest.

Аннотация: The effect of climate change on the distribution, intensity, and transforming role of wild fires is considered. A general overview of the current wild fire regimes (WRs) and impacts on forest ecosystems and environment is provided. One distinctive feature of WRs is the increasing frequency of disastrous wild fires. The application of various remote sensing instruments has shown that the average vegetation wild fire area in Russia for 1998-2010 accounted for 8.2 +/- 0.8 x 10(6) ha, with about two-thirds of wildfires occurring on forest lands and half on the forested lands. The average annual fire carbon balance during the above period was 121 +/- 28 Tg C yr(-1), including 92 +/- 18 Tg C yr(-1) emitted from the forested land. The forecasts based on the General Circulation Models suggest the dramatic acceleration of fire regimes by the end of the 21st century. Taking into account the increase in the dryness of the climate and the thawing of permafrost, this will likely lead to a dramatic loss of forested area and the impoverishment of the forest cover over a major part of the forest zone. A transition to adaptive forestry would allow a substantial decrease of the expected losses. This paper takes a brief look at the general principals of adapting forest fire protection system to climate change, which is considered an integral part of the transition to sustainable forest management in Russia.

Аннотация: This research is an attempt to study seasonal translocation patterns of photoassimilated carbon within trees of one of the high latitudes widespread deciduous conifer species Larix gmelinii (Rupr. Rupr). For this purpose, we applied whole-tree labeling by (CO2)-C-13, which is a powerful and effective tool for tracing newly developed assimilates translocation to tissues and organs of a tree. Experimental plot has been established in a mature 105-year-old larch stand located within the continuous permafrost area near Tura settlement (Central Siberia, 64A degrees 17'13aEuro(3)N, 100A degrees 11'55aEuro(3)E, 148 m a.s.l.). Measurements of seasonal photosynthetic activity and foliage parameters (i.e., leaf length, area, biomass, etc.), and sampling were arranged from early growing season (June 8, 2013; May 14, 2014) until yellowing and senescence of needles (September 17, 2013; September 14, 2014). Labeling by C-13 of the tree branch (June 2013, for 3 branch replicates in 3 different trees) and the whole tree was conducted at early (June 2014), middle (July 2014), and late (August 2013) phase of growing season (for different trees in 3 replicates each time) by three pulses [(CO2)max = 3000-4000 ppmv, (CO2)-C-13 (30 % v/v)]. We found at least two different patterns of carbon translocation associated with larch CO2 assimilation depending on needle phenology. In early period of growing season (June), C-13 appearing in newly developed needles is a result of remobilized storage material use for growth purposes. Then approximately at the end of June, growth processes is switching to storage processes lasting to the end of growing season.

Аннотация: The effect of pine provenance trials of Pinus sibirica Du Tour and Pinus koraiensis Siebold et Zucc. grown in Krasnoyarsk and Khabarovsk krais on the chemical and biological parameters of gray forest and brown forest soils in the rhizosphere and between rows of plantations is compared. It is shown that the interspecies heterogeneity of pines affects the chemical composition of the soil, the enzymatic and microbiological activity, and the formation of prokaryotic microbiomes. It is noted that the biodiversity of prokaryotes is more strongly determined by the features of soil types than by the inter- and intraspecies heterogeneity of pines and by the effect of their roots. The phyla Proteobacteria, Acidobacteria, and Actinobacteria dominate in both soil types and together account for 75-85% of the total number of type-specific 16S rRNA gene sequences in each soil.
