Аннотация: This article shortly characterizes the forest reserves of one of the largest forest regions of Russia - Krasnoyarsk region. It can be seen in dynamics that for the last 50 years the quality of the forest reserves has degenerated significantly. This degeneration is caused by the irrational and unsustainable forest management. Autrhors propose some basic principles for sustainable forest management and provide some socio-economic mechanisms of solving the problem of illegal logging.

    Лесоэкологические последствия пожаров в кедровниках Южного Прибайкалья
[Текст] : материалы временных коллективов / Ю. Н. Краснощеков, М. Д. Евдокименко, Ю. С. Чередникова // География и природные ресурсы. - 2013. - № 1. - С. 33-42. - Библиогр. в конце ст.
Аннотация: Проанализированы данные экспериментальных исследований по послепожарной динамике лесов в Южном Прибайкалье. Установлено, что низовые пожары подстилочно-гумусового вида в засушливые годы являются основным деструктивным фактором в динамике кедровых лесов. Воздействие низового огня сопровождается усыханием деревьев, а жизнеспособность выживших после пожаров кедров зависит от характера и тяжести огневых повреждений. Приведена характеристика нижних ярусов растительности и ее динамика под влиянием пожаров разной интенсивности. Показано негативное воздействие низовых пожаров на изменение запаса, качественного фракционного состава органогенных горизонтов почв и их химического состава. We examine the data from experimental investigations into the post-fire dynamics of Siberian stone pine forests in Southern Cisbaikalia. The analysis revealed that creeping fires of the litter-humus type in dry years constitute the main destructive factor in the dynamics of Siberian stone pine forests. Creeping fires involve desiccation of trees, while viability of Siberian stone pine trees that have survived the fire depends on the character and severity of fire-related tree injuries. We provide a characteristic of the lower layers of vegetation and its dynamics under the influence of fires of different intensities. It is shown that creeping fires have a negative influence on changes in reserves, qualitative fiber length distribution of organogenic soil horizons, and on their chemical composition.

    Influence of drying of the samples on the transformation of nitrogen and carbon compounds in mountain-meadow alpine soils
/ M. I. Makarov [et al.] // Eurasian Soil Sci. - 2013. - Vol. 46, Is. 7. - P778-787, DOI 10.1134/S1064229313070053. - Cited References: 32. - This study was supported by the Russian Foundation for Basic Research (project no. 10-04-00780). . - 10. - ISSN 1064-2293

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: We present an intra-annual stable carbon isotope (13C) study based on a labeling experiment to illustrate differences in temporal patterns of recent carbon allocation to wood structures of two functional types of trees, Podocarpus falcatus (a late-successional evergreen conifer) and Croton macrostachyus (a deciduous broadleaved pioneer tree), in a tropical mountain forest in Ethiopia. Dendrometer data, wood anatomical thin sections, and intra-annual 13C analyses were applied. Isotope data revealed a clear annual growth pattern in both studied species. For P.falcatus, it was possible to synchronize annual 13C peaks, wood anatomical structures and monthly precipitation patterns. The labeling signature was evident for three consecutive years. For C.macrostachyus, isotope data illustrate a rapid decline of the labeling signal within half a year. Our 13C labeling study indicates a distinct difference in carryover effects between trees of different functional types. A proportion of the labeled 13C is stored in reserves of wood parenchyma for up to 3yr in P.falcatus. By contrast, C.macrostachyus shows a high turnover of assimilates and a carbon carryover effect is only detectable in the subsequent year.

variograms -- typological series -- water regime -- litter

Аннотация: A typological series of native Betula pubescens Ehrh. dendrocenoses along the channel of a river crossing a bog was studied. The variability of the mineral element reserves is described by geostatistical methods as the sum of a trend, autocorrelation, and random components. The contribution of deterministic and random components has been assessed in the years with average precipitation and in the year of 2007 with high and long-term flooding. The empirical variograms and the parameters of the model variograms are presented. The class of the spatial correlation of the ash reserves is described. A primary cause of the ash content's variability is the specific water regime, which is determined by the following: (i) the abundance and duration of the spring floods responsible for the silt mass brought by the river and (ii) the draining effect of the intrabog river, the distance from which provided the formation in the forest of the ground cover with the specific species composition and ash content. The falloff of the arboreal layer in the bog birch forests formed the fundamental mineral background of the litter.

phytomass -- stand -- grass bush layer -- easily mineralizable and stable organic soil matter -- fire intensity

Аннотация: A change in the mass and composition of organic matter in the phytomass and soil of pine forests affected by mid-intensity and high-intensity fires is considered. It is shown that a mid-intensity fire did not catastrophically affect the pool of carbon in the middle-aged pine forests of the subtaiga forest-steppe and the taiga higher belt areas in the southwest of the Baikal region. Five years after a high-intensity fire, the carbon reserves in a mature taiga pine forest remain 20% lower than in an unaffected pine forest. Compared with the reference figures, the mass of C and soil cover in the stand phytomass decreased by 18 and 63%, respectively. In the easily mineralizable fraction of organic matter, the reserves of carbon decreased by half owing to burnout of waste wood (by 64%) and root detritus (by 50% compared with the reference tree stand figures).

Аннотация: The results of experimental investigations of the postpyrogenic dynamics of the widespread rawhumus podzols under Pinus sibirica forests in the southern Lake Baikal basin are discussed. Ground fires transform the diagnostic surface organic soil horizons into organic pyrogenic horizons (Opir, OL/Opir, and AOpir). The adverse effect of ground fires of different intensities on the changes in the reserves, the fractional composition of the litters, and the chemical composition of the organic horizons is shown. The soils of dark coniferous forests are inclined to long-lasting restoration. The Pinus sibirica regrowth under the canopy of deciduous species serves as the basis for the restoration of native stands and the formation of the soils characteristic of the southern part of the Lake Baikal basin.

    Soil formation in the technogenic forest-steppe landscapes of the Nazarovskaya Depression in western Siberia

Аннотация: The soil formation was studied in the 21- to 35-year-old pine plantations created on the overburden dumps of the Nazarovskaya Depression without applying the material of the humus horizon. The surface technogenic formations under the pine plantations belong to the group of naturfabricats (surface formations devoid of the humus horizon and composed of natural substrate). The morphological characteristics, bulk chemical and particle-size compositions, and labile properties of the soils indicate that the accumulation and transformation of organic matter are dominant processes in the artificially planted forests. The accumulation of organic residues and destruction and humification are tightly related to the environmental conditions transformed by the technogenesis and conceal other processes forming the soil profiles. Quasizems created for agricultural production purposes were the objects of the study. They were formed by covering the technically planned overburden rocks with the material of humus layers. The thickness of the humus horizons of the quasizems varies greatly (25-64%); the variation of the humus reserves in them is 34-122%. Middle-profile horizons have not been formed by the present time.

Аннотация: The influence of climatic and forest conditions on space and time variations in the concentrations and export of two forms of dissolved carbon (DOC) and dissolved inorganic carbon (DIC) in rivers of the Central Siberian cryolithic zone (Yenisei River basin) draining territory characterized by relatively homogeneous composition of parent rocks was analyzed. Rivers of the northern (Tembenchi and Kochechum rivers), central (Nidym River), and southern parts (Lower Tunguska and Podkamennaya Tunguska rivers) of the Central Siberian Plateau traps were selected as objects of investigation. Along with growth of the water flow rate, increase in the productivity and reserves of carbon in the biogeocenosis of the cryolithic zone leads to significant (more than twice) increase in export of terrigenous DOC and DIC to the hydrographic network.

Аннотация: The biomass of large invertebrates was studied in the soils of forest ecosystems in the forest-tundra and southern taiga of Central Siberia. Its formation is shown to be controlled by the integrated effect of the soil and climatic conditions. The distribution of the zoomass according to the main taxonomic groups testifies to the higher functional significance of the large saprophagous invertebrates in the ecosystems of the southern taiga compared to those of the forest-tundra. The quantitative contribution of the invertebrates-destroyers to the organic matter decomposition was assessed on the basis of field experiments; it was shown to be determined by the quality of the material decomposed irrespective of the conditions and time of its exposition. Every year, soil saprophages decompose 0.5-2.0% of the total phytodetritus reserves in the forest-tundra and 3-14% in the southern taiga amounting to 12-54% of its losses upon decomposition.

Аннотация: The influence of ground fires of different intensities on the nitrogen pool in the sandy soils under pine forests of the middle taiga zone after their experimental burning was studied. The contents of total nitrogen and its ammonium form increased due to the input of great amounts of plant falloff during the first year after the fire. Within two years after the fire, the content of nitrogen and the percentages of its forms approached their initial values before the fire. The adverse effect of the pyrogenic factor on the biological activity of the sandy podzols was shown.

Аннотация: The results of studying the dynamics of forest litter properties in the loci of a Siberian moth (Dendrolimus sibiricus) mass outbreak are considered. As a fir forest defoliated by this pest burns, the reserves and fractional composition of the forest litter, its actual acidity, and its chemical composition drastically change. Upon the burning out of such forests, the litter complex of invertebrates is fully destroyed and begins restoring only two years after the fire.

Аннотация: The Sayano-Shushensky Nature Reserve is a standard primeval locus of high conservation value which remained undisturbed landscapes within the Altai-Sayan Mountain Land. In the plant cover the altitudinal belts are clearly expressed. The northern part of the Sayan-Shushensky reserve is included in moist areas of the Altai-Sayan forest vegetation zone and the Southern part of it is included in insufficiently moist areas of Central Asian forest zone. The ground vegetation of the reserve is presented by high-mountain tundra, meadows and shrub thicket sites, high-mountain open Pinus sibirica D u. T o u r. and Larix sibirica L e d e b. woodland, dark and light coniferous taiga, coniferous subtaiga, forest-steppe and steppe. As a whole forests occupy somewhat about 60% of the territory. Ecocenotic groups of species found in individual phytocoenoses in river basins of the northern part of the nature reserve are qualitatively different in composition and share from those ones found in the southern river basins. In the north, the high mountain ecocenotic species group enjoys the greatest abundance, and forest-meadow, taiga, and bog species are also represented substantially. Steppe and forest-steppe species are absent. Alpine, steppe, and forest-steppe species are found in equal shares in the southern part of the forest reserve. Invasive species are quite many. Taiga species contribution is three times less than in the north of the reserve. Conditions climatically optimal for the greatest species diversity are the result of a perfect balance of heat and moisture characteristics of subtaiga/forest-steppe altitudinal belt complexes (ABC). However, changes in phytochorological- and alpha-diversity of individual phyl.ocoenoses are influenced by ecological and phytocoenotic factors combined. The biggest number of species in the reserve occurs along the forest distribution boundaries - in subtaiga and high mountain open woodland whereas species are the fewest in mountain taiga. Conversely, phytomass loading is the greatest in mountain taiga and it decreases gradually towards alpine tundra and steppes.

Аннотация: The reserves of carbon in peat deposits and peaty and peat bog soils of Russia comprise 44.2 Gt C of humic substances (37.3% of the total reserve of C), 44.7 Gt C (37.8%) of insoluble residue, and 21.1 Gt C (17.8%) of polysaccharides, The carbon pool of humic acids constitutes 25.0 Gt and that of fulvic acids reaches 19.1 Gt. Humic acids predominate in low-moor peat, whereas fulvic acids predominate in high-moor peat. Transitional pear deposits contain approximately equal amounts of fulvic and humic acids. About 89-91% of the carbon of humic substances in different types of peat is represented by heterogeneous complexes of the first and third fractions.

    Pyrogenic transformation of organic matter in soils of forest bogs
[Text] / T. T. Efremova, S. P. Efremov // Eurasian Soil Sci. - 2006. - Vol. 39, Is. 12. - P1297-1305, DOI 10.1134/S1064229306120039. - Cited References: 31 . - 9. - ISSN 1064-2293

Аннотация: Natural fires on forest bogs significantly affect all the groups and fractions of peat organic matter. The type and intensity of the fires are responsible for the depth of the pyrogenic transformation of peat. In the course of thermal destruction of peat organic matter, humus substances (humic acids in particular) are accumulated, which leads to changes in the type of humus; the humus reserves may increase by 1.5-8 times. Several ways of the formation of humus components related to the intensity of a fire are suggested. The regressive evolution of bog ecosystems caused by fires is a reversible process. The humus status of pyrogenically transformed horizons and their morphology are preserved within the peat deposit as a relic characteristic of the discrete metamorphosis of the soils.

Аннотация: The impact of long-term seasonal soil freezing, drought, and waterlogging on the rhizosphere of young Scots pine trees (Pinus sylvestris L., age class 1) has been simulated in experiments. The results have shown that cold stress exposure leads to reduction of the rates of linear and radial tree growth and of chlorophyll content in needles, a shift in the peak of starch content, and initiation of free amino acid deposition in the aboveground plant parts. Drought activates utilization of carbohydrate reserves and amino acid accumulation in the root bast, whereas soil waterlogging stimulates deposition of carbohydrates but causes a decrease in the levels of chlorophyll and amino acids in all plant tissues.

Аннотация: The hygroscopic properties of the litter of coniferous (larch and pine) and deciduous (aspen and birch) stands were studied in terms of isotherms of water-vapor sorption and with use of thermal analysis methods (TG, DSC). It was found that most of the monolayer capacity belongs to subhorizons OL and OF of the larch and pine forest litters. The larch plantation litter has the highest hydrophilicity. DSC results show that the water is most strongly associated with the litter substance in subhorizon OL in coniferous plantations and OH in deciduous ones. The moisture supply in the litter of coniferous stands is greater than in deciduous ones.
