Аннотация: Исследован состав жирных кислот (ЖК) фосфолипидов мембран клеточных стенок микроорганизмов в подзолистых почвах сосняков Средней Сибири. Отмечено плавное снижение живой микробной биомассы в исследуемом минеральном слое почвы от поверхности до глубины 1 м. Несмотря на падение биомассы в два раза на нижних горизонтах, ее уровень оставался достаточно высоким - 12-14 нмольЖК/г почвы. Коэффициент сходства композиций жирных кислот почв облесненного и необлесненного участков составлял 0.85. Коэффициент богатства ЖК снижался с глубиной минерального слоя почвы с одновременным увеличением различий в профилях жирных кислот.

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: The microbial activity of peat soils was studied in boggy larch forests and in an oligo-mesotrophic bog in the basins of the Kochechum and Nizhnaya Tunguska rivers (central Evenkia). It was found that the organic matter transformation in the peat soils of all the plots is mainly performed by oligotrophic bacteria composing 88-98% of the total bacterial complex. The major contribution to the organic matter destruction belonged to the heterotrophic microorganisms, the activity of which depended on the permafrost depth and the soil temperature, the soil acidity, and the botanical composition of the peat. Peat soils were characterized by different activities as judged from their microbiological and biochemical parameters. The functioning of microbial communities in the studied ecotopes of the permafrost zone was within the range of natural variations, which pointed to their ecological stability.

Аннотация: It is shown that the diagnostics of the stage of woodland soils affected by wildfires and forest cuts can be determined by the evaluation indexes of the range of the scale of abundance of typical ecologic-and-trophic groups of microorganisms (ECTGM), microbiological activity coefficients, reserve and abundance fluctuations, and metabolism. The degree of impact of the technogenic emissions on the forest cover, soil, and phyllosphere according to ECTGM abundance on the diagnostic environments and their fermentative activity is expressed with the help of an advisability functional relation.

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: Plant species exert strong effects on ecosystem functions and one of the emerging, and difficult to test hypotheses, is that plants alter soil functions through changing the community structure of soil microorganisms. We tested the hypothesis for atmospheric CH4 oxidation by using soil samples from a Siberian afforestation experiment and exposing them to C-13-CH4. We determined the activity of the soil methanotrophs under different tree species at three levels of initial CH4 concentration (30, 200 and 1000 ppm) thus distinguishing the activities of low- and high-affinity methanotrophs. Half of the samples were incubated with C-13-enriched CH4 (99.9%) and half with C-12-CH4. This allowed an estimation of the amount of C-13 incorporated into individual PLFAs and determination of PLFAs of methanotrophs involved in CH4 oxidation at the different CH4 concentrations. Tree species strongly altered the activity of atmospheric CH4 oxidation without appearing to change the composition of high-affinity methanotrophs as evidenced by PLFA C-13 labeling. The low diversity of atmospheric CH4 oxidizers, presumably belonging to the UCS alpha group, may explain the lack of tree species effects on the composition of soil methanotrophs. We submit that the observed tree species effects on atmospheric CH4 oxidation indicate an effect on biomass or cell-specific activities rather than by a community change and this may be related to the impact of the tree species on soil N cycling.

Аннотация: The paper focuses on investigating the densities of different ecological trophic groups of soil microorganisms, cellulose decomposition rates, and respiration of cryogenic forest soils in the north of Central Siberia and those of the southern taiga subzone, including those affected by surface wildfires. Psychrotolerant bacteria and micromycetes were found to dominate these soil complexes. The biological activity of the upper soil horizon in the north appeared to be close to that in the south, although the growing season in the former area is shorter compared to the latter.

Аннотация: In deep peat soils of forest-swamp ecosystems of West Siberia, the structural, dynamic and functional features of microbial complexes are estimated. Data on biological and chemical activity of peat deposits in the context of processes of organic matter decomposition and humus accumulation are presented. Quantitative indicators of microbiological mineralization and soil oligotrophicity are given, and their coefficients are calculated. The pool of microorganisms of a 8 meter thick layer is calculated for estimating the degree to which the forest-swamp soils are enriched with microflora.

Аннотация: The biomass of two groups of microorganisms was studied in gray forest soils under six tree species (spruce, Scotch pine, Arolla pine, larch, birch, and aspen) and in the soil of a layland (a clearing in the forest) using kinetic methods. The biomass was the highest in the soil of the layland. The lowest (19.4 mu g C/g of soil) biomass of heterotrophic microorganisms was found in the soil under the birch trees, and the highest one (41.7 and 32.0 mu g C/g), under the pine and spruce ones. The biomass of denitrifying microorganisms was lower by thirty times than that of the heterotrophic ones. In the soils under the pine and spruce trees (8.4 and 9.2 mu g C/g, respectively), the biomass of the denitrifying microorganisms was the lowest; under the birch and larch trees, it was the highest (16.7 and 13.7 mu g C/g).

Аннотация: The introduction of Trichoderma viride spores (10(8) CFU per 1 cm(2)) essentially changed the structure of micromycetes in the soils of tree nurseries in Krasnoyarsk region. During the first 20 days, in the variants with dark gray forest soils and podzolized chernozems, the total number of fungi decreased by 3-4 and 1.5 times, respectively, as compared to that in the control plots. During the intense development of the introduced microbes, the species composition of the soil fungi changed considerably. The treatment of Scots pine seeds with metabolites of Trichoderma fungi, as well as Pseudomonas and Bacillus bacteria, in the form of water suspensions, biopreparations, and dry spores promoted an increase in the yield of seedlings and improve their morphometric parameters. At the end of the growing period, the treatment with Trichoderma and the biopreparation on its basis increased these parameters, on average, by 18-70%, and the treatment with bacteria increased the same parameters by 13-15%. The application of microbial preparations improved the phytosanitary state of the soils in the studied tree nurseries. The use of the strains of indigenous microorganisms might be feasible for solving bioremediation problems more successfully in particular regions.

Аннотация: New data on the structure, dynamics, and functioning of microbiological complexes in deep peat soils of Western Siberia are obtained. The highest population densities of microorganisms are registered in the zone of active peat accumulation with oxidizing conditions (I-Ox, 0-10 cm), in the zone with alternating reducing and oxidizing conditions (IIOx-Red, 50-100 cm), in the zone with permanently reducing conditions (IIIRed1, 250-350 cm), and in the zone with sharply reducing conditions (IVRed2, 550-675 cm). The oxidative type of microbial metabolism initiated by aerobic and facultative anaerobic microorganisms of the heterotrophic cycle is typical of the studied low-moor peat soils.

Аннотация: It is shown that larch of the prefire generation is the main edificator at the early stages of progressive successions in burned-out areas. Its environment-forming effect manifests itself most strongly in the phytogenic field of living trees, where edaphic conditions similar to those in primary larch forests are formed within ten years after the fire. This is accompanied by an increase in the numbers of microorganisms utilizing organic and mineral nitrogen, as well as in the rate of nitrogen mineralization in plant microgroups of this zone. Hence, living trees remaining in a burned-out area promote restoration of the initial edaphic conditions.

Аннотация: The experimental data on the transformation of properties of soddy-deeply podzolic soils and raw humus burozems under fir forests defoliated by the Siberian moth Dendrolimus sibiricus are analyzed. In the first two months after the addition of Siberian moth excrements to the forest litter, the population of all ecological-trophic groups of microorganisms was shown to increase by 13 times, that of ammonifying phototrophs and microorganisms, taking part in humus mineralization, by 42 and 9 times, respectively. The leaching of water-soluble carbon from litters in forests defoliated by the Siberian moth was by 21-26% higher than that from litters of control ones. A year later, it was reduced to 14%. The content of exchangeable hydrogen and total acidity decreased, and the degree of base saturation increased. Within 5-6 years after the Siberian moth invasion, the transformation of physicochemical, chemical, and microbiological properties of soils was specified by succession development of the plant cover.

Аннотация: Experimental data are analyzed that concern the effect of zoogenic debris on the properties of soddy deep podzolic soils and raw-humus brown soils characteristic of southern taiga forests in the Yenisei region of Siberia. It is shown that the influence of excrements of Siberian moth larvae on the soil microflora lasts for two or, at most, three growing seasons. Zoogenic plant debris failing on the ground surface during tree stand defoliation is a short-acting but powerful stimulant of biological activity in the litter; hence, it has a considerable effect on soil properties. This effect is enhanced by changes in ecological conditions that occur upon defoliation. The influence of the cenotic factor on biogenic soil properties is manifested more strongly in the organogenic horizons. The communities of microorganisms involved in the nitrogen and carbon cycles are dominated by prototrophic forms in the normal fir forest and by pedotrophic forms in the forest defoliated by pests.

Аннотация: In the southern-taiga low grass-green moss fir forest completely defoliated by the Siberian moth, the rate of soil respiration in the third year after the pest population outbreak was 1.5 times higher than in an undisturbed tree stand. This was explained by a significant increase in the abundance and activity of soil microorganisms in the pest-defoliated forest, which occurred due to the qualitative changes in the litter composition and the increased temperature and moisture in the upper soil layers. The rate of carbon emission from the soil in the defoliated forest was 41.7 kg/ha per day, compared to 28.3 kg/ha per day in the undisturbed fir forest.

Аннотация: The quantitative composition of various trophic groups of microorganisms and the enzyme activity of forest cryogenic soils in Central Evenkia was studied. The preferential development of complexes of psychrotolerant bacteria and micromycetes was found. During a short growing period, the biological activity of upper organic horizons in northern soils is comparable with that in southern taiga soils of Siberia. The microflora and biological activity of southern taiga soils in Central Siberia is understood rather completely. At the same time, information on the biogenic properties of forest soils in northern Siberian regions is scarce, though there are representative data on sylvicultural, soil, physiological, and biochemical studies of forest biogeocenoses.

Аннотация: The structure and functions of the microbial complexes in the soils after surface fires of different intensity were studied. The fires of high and medium intensity were found to lead to a significant decrease in the number and functional activity of microorganisms participating in the nitrogen-carbon cycle. The degree of changes in the postfire status of the soil microbocenoses was revealed to be related to the joint action of pyrogenesis and the hydrothermal conditions at the moment of the fire rather than to the fire intensity. The favorable combination of the elevated soil moisture and soil heating stimulates the microbiological processes of organic matter mineralization, thus, improving the forest-growing conditions for the pine forests. The microbial biomass, basal respiration, and the microbial metabolic coefficient are shown to adequately reflect the postfire status of the microbial complexes.
