Аннотация: Measurements were made of height, diameter and number of trees in the Siberian Afforestation Experiment for monoculture plots with six tree species, established in the central part of the Krasnoyarsk region. Almost 150 felled trees were measured to evaluate aboveground biomass fractions determine biomass dynamics through stand development. Local uncertainties in needle mass dynamics were revealed for Scots and arolla pine stands. Carbon storage was evaluated for live trees and in biomass of dead trees and fall of branches and needles. Over the 35 years of stand development, these species accumulated 100 to 300 m3/ha of wood, with a likely carbon content about 25 to 75 Mg/ha. The trees also added a large amount of C to the soil in fallen leaves, branches, and dead roots. In this region, Norway spruce and arolla pine form the longest-lived forests, and may have higher productivities than the other species later in stand development.

Aspen bark photosynthesis and its significance to remote sensing and carbon budget estimates in the boreal ecosystem
: материалы временных коллективов / V. I. Kharuk // Water, air & soil pollution. - 1995. - Vol. 82, № 1-2. - С. 483-497. - Библиогр. в конце ст.
Аннотация: Our findings have shown that the spectral characteristics of aspen bark differ considerably from the "grey body" representations typically utilised in radiative transfer models. Also, since the bark and leaf canopy fractions have different C assimilation capacities, the partitioning of canopy Chl into leaf and bark strata should improve C assimilation estimates. Remote sensing technology must be relied upon, especially in vast and largely in accessible regions such as the boreal biome, for landscape- and regional-scale studies of C budgets. In these studies, estimates of forest productivity and C exchange currently rely on spectral indices obtained from remote satellite/aircraft sensors; these spectral ratios are used to indirectly estimate C assimilation through correlation with chlorophyll and photosynthetic capacity.

Аннотация: The content and fractional composition of alcohol soluble phenolic acids (PhA) in cells with different degree maturation and lignification in the course of early and late wood formation in the pine (Pinus sylvestris L.) stem during vegetation were studied. Phenolic compounds (PhC), extracted by 80% ethanol, were divided into free and bound fractions of PhA. In turn, the esters and ethers were isolated from bound PhA. The contents of all substances were calculated per dry weight and per cell. Considerable differences have been found to exist in both the contents and the composition of the fractions PhA on successive stages of tracheid maturation of early and late xylem. Early wood tracheids at all secondary wall thickening steps contained PhC less and free PhA more than late wood tracheids. Throughout earlywood tracheid maturation, the pool of free PhA per cell declined at the beginning of lignification and then increased gradually while that of bound PhA decreased. The maturation of late wood tracheids were accompanied by the rise of free PhA pool and the diminution of bound PhA pool. In the composition of bound PhA, the ethers were always dominant, and the amount of that in earlywood cells was less than in latewood cells. The cells of early xylem at all steps of maturation contained more of esters. The sum total of free hydroxycinnamic acids, precursors of monolignols, gradually decreased during early xylem lignification as the result of the reduction of the pools of p-coumaric, caffeic, ferulic and synapic acids, while that of their esters rised. In the course of late xylem lignification, the pools of free p-coumaric, ferulic and, especially, synapic acids increased. Simultaneously, the amount of ferulic acid ester and synapic acid ether increased too. According to the data, lignin biosynthesis in early xylem and late xylem occurs with different dynamics and the structure of lignins of two xylem types might be different too.

Аннотация: The results of the study of the qualitative composition and relative content of highly volatile compounds from the needles in two natural pine populations located in the forest-steppe zone in the south of Central Siberia are presented. Altogether, 89 components were isolated. Analysis of intra- and interpopulation variability of 31 terpenoids (mono- and sesquiterpene fractions) was conducted. The spatial structure of the variance of features was analyzed. Significant interpopulation differences in the content of most compounds were registered. It was determined that, as growing conditions deteriorate, the mass fraction of lighter monoterpene compounds (especially alpha-pinene) is increased within populations, and qualitative diversity of the components of essential oils is decreased. The groups of terpenoids, the relative content of which is to a different degree associated with interpopulation differences and variety of the growing conditions of trees within populations, were isolated.

Аннотация: The prediction results of large-scale forest fire development are given for Siberia. To evaluate the fire risks, the Canadian Forest Fire Weather Index System (CFFWIS) and the Russian moisture indices (MI1 and MI2) were compared on the basis of the data of a network of meteorological stations as input weather parameters. Parameters of active fires were detected daily from the NOAA satellite data for the period of 1996-2008. To determine the length of the fire danger season, the snow cover fractions from Terra/MODIS data (2001-2008) were used. The features of fire development on territories with different types of flammable fuel are considered. The statistical analysis of the areas and number of fires typical of each vegetation class is made with the use of the GLC2000 vegetation map. A positive correlation (similar to 0.45, p < 0.05) between the cumulative area of local fires and the MI1 and Canadian BUI and DMC indices is revealed. The Canadian ISI and FWI indices describe best the diurnal dynamics of fire areas. The above correlations are higher (similar to 0.62, p < 0.05) when we select the fires larger than 2000-10000 ha in size for the forested areas. Other cases point to the lack of a linear relation between the fire area and the values of all indices, because the fire spread depends on many natural and anthropogenic factors.

Аннотация: The content and composition of alcohol soluble phenolic acids (PhAs) were studied during cell xylem growth in course of wood annual increment formation in the trunks of Scots pine. Cells of the cambium zone, two stages of expansion growth, and outset of secondary thickening zone (before lignification) within the period of formation of early wood xylem were subsequently isolated from trunk segments of 25-year-old trees with constant anatomical and histochemical control. The amount of free and bound forms of phenolic acids extracted from tissues by 80% ethanol, as well as their ethers and esters, were calculated both per dry weight and per cells. The substantial alteration in content, proportion of fractions and composition of acids has been found between the cambium zone and the outset of secondary thickening of tracheids, and the character of variation depended on the calculation method. The amount of free and bound PhAs and esters and especially ethers calculated per cell had increased at the first stage of extension growth, reduced at the second, and increased in the outset of secondary wall deposition. The pool of bound acids was more than acids by 2-5 times depending on the stage of development of the cells. Sinapic and ferulic acids dominate among free hydroxycinnamic acids. The composition and the content of hydroxycinnamic acids in esters and ethers also depended on the stage of development of the cells. p-Coumaric and sinapic acids were the main aglycons in ethers in the cambium and sinapic and caffeic acids were in the other stages. The esters from cambium included mostly p-coumaric acid and those at other stages of development were sinapic and ferulic acids. The esters included benzoic acid at the first stages of growth. The pool of these esters decreased from the first phase of growth until the outset of cell wall thickening. The level of free benzoic acid increased respectively.

Аннотация: The thermal degradation of organic matter was studied in cryogenic soils with methods of thermal analysis: differential scanning calorimetry and thermogravimetry (DSC and TG, respectively). The DSC curves of most of the samples within the temperature range from 221-247A degrees C to 600A degrees C were characterized by the presence of one wide exothermic peak (at 311-373A degrees C) with a shoulder (or without it) on the descending branch at a temperature of about 400A degrees C. This was connected mostly with the destruction of thermolabile compounds (oligo- and polysaccharides) and with the oxidation of low-aromatic complexes of plant residues and humus substances. Two exothermic peaks at 337-373A degrees C and 448-492A degrees C were found for some samples from the organic horizons. The high-temperature peaks were caused by the thermal destruction of lignin. The fraction of the thermolabile organic matter of the soil (237-261aEuro broken vertical bar 331-377A degrees C) reached 59-73% in the organic and 52-59% in the organomineral and mineral horizons.

Аннотация: The specificity of the group and fraction composition of the organic matter in peat soils drained to a different extent that have developed for a 20-to 25-year period of hydro-and forest amelioration was characterized using the methods of multidimensional statistics. The differences in the organic matter of the soils studied are mainly determined by the contents of humic and fulvic acid of fractions 1 and 3, as well as of hemicelluloses and cellulose. The degree and depth of the humification are inversely related to the soil moisture and directly related to the peroxidase activity.

Аннотация: The specificity of the group and fraction composition of the organic matter in peat soils drained to a different extent that have developed for a 20-to 25-year period of hydro-and forest amelioration was characterized using the methods of multidimensional statistics. The differences in the organic matter of the soils studied are mainly determined by the contents of humic and fulvic acid of fractions 1 and 3, as well as of hemicelluloses and cellulose. The degree and depth of the humification are inversely related to the soil moisture and directly related to the peroxidase activity.

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.

Pyrogenic transformation of organic matter in soils of forest bogs

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 deposition of cellulose, matrix polysaccharides and lignin during secondary cell wall development of early- and latewood in larch (Larix sibirica Ldb.) were studied using biochemical and histochemical methods. Active tissues at successive stages of secondary cell wall development were sampled from larch trunk and characterized by morphological parameters and the content of cellulose, lignin and matrix hemicelluloses, being the structural base for lignification. Matrix polysaccharides were divided by their solubility in 4 % and 24 % KOH and neutral medium. All data were accounted per dry weight and per cell. The amount of biomass (as cell wall cross-section area) deposited before lignification was more in earlywood tracheids than in latewood ones. In contrast. the amount of cellulose at this stage was more in latewood tracheids. The intensity of cellulose synthesis was the highest at the initial stage of lignin deposition in both earlywood and latewood and then declined towards to mature xylem. The intensity of lignin deposition was the highest at the last stage of secondary cell wall development during earlywood formation and from the outset of latewood lignification, dropping towards mature xylem. The contents of A and B hemicellulose fractions linked or not with cellulose, before and after beginning of lignification were different during earlywood and latewood formation. Before lignin deposition, the content of B-4 fraction in both earlywood and latewood was practically equal as well as of B-24, while the amount of A-4 fraction before lignification of early xylem was two times more than that of latewood. This shows different matrix base for the beginning of lignification. All together can be the reason for different physicochemical properties of two types of wood in larch.

Аннотация: The influence of optimal and contrasting temperatures on the fractional composition of proteins and respiration of germinating seeds of Gmelin larch (Larix gmelinii (Rupr.) Rupr.) and Siberian larch (Larix sibirica Ledeb.) was revealed. The dominance of globulins (salt-soluble fraction) and insoluble proteins was noted in viable air-dry seeds of larch. Optimal and contrasting temperatures of germination of seeds caused significant changes in the content and dynamics of separate fractions of protein, the contrasting temperatures causing greater changes: increasing in the content of insoluble proteins, intense consumption of globulins at separate stages of germination. Respiration of the seeds during germination at contrasting temperatures also increased more than at an optimal temperature. Thermal regime of germination affected the character of relations between the respiration rate and contents of different protein fractions.

C and N availability affects the N-15 natural abundance of the soil microbial biomass across a cattle manure gradient

Аннотация: The availability of C and N to the soil microbial biomass is an important determinant of the rates of soil N transformations. Here, we present evidence that changes in C and N availability affect the N-15 natural abundance of the microbial biomass relative to other soil N pools. We analysed the N-15 natural abundance signature of the chloroform-labile, extractable, NO3-, NH4+ and soil total N pools across a cattle manure gradient associated with a water reservoir in semiarid, high-desert grassland. High levels of C and N in soil total, extractable, NO3-, NH4+ and chloroform-labile fractions were found close to the reservoir. The delta N-15 value of chloroform-labile N was similar to that of extractable (organic + inorganic) N and NO3- at greater C availability close to the reservoir, but was N-15-enriched relative to these N-pools at lesser C availability farther away. Possible mechanisms for this variable N-15-enrichment include isotope fractionation during N assimilation and dissimilation, and changes in substrate use from a less to a more N-15-enriched substrate with decreasing C availability.

The research sites were larch forests, they are situated on Nizhne-Tungusskoe Plateau. Larch forests of feather-moss and lichen types (110 and 380 years old) were formed on 'ochric podbur' soils. Litter stocks are 3.5-4.5 kg m-2 with thickness 10-25 cm. Cryomezomorphic northern taiga soils contains 38-73 t (carbon) ha-1. Pool of fast mineralized OM has average value 38.1 t (carbon) ha-1, including 20.5 and 6.4 t (Carbon) ha-1 of labile compounds on surface and in the soil, and 11.2 t (carbon) ha-1 of mobile OM. Microbial mass reaches 1.78-3.47 t (carbon) ha-1, its proportion is 3.6-4.9% of the total OM carbon. Zoomass of feather-moss larch forest is 0.20-0.61 * 10-2, in lichen larch forest -0.01-0.07 * 10-2 t (carbon) ha -1. A pool of resistant to biological decomposition and bonded to mineral soil matrix OM is 17.7 t (carbon) ha-1 and it varies from 18.6 to 29.0 in feather-moss larch forest, and from 6.4 to 17.0 t (carbon) ha-1 in lichen larch forest. Two-years field experiment has been performed to determine transformation rates of various plant litter fractions and to clarify the role of soil biota in these processes. The results showed participation of all biota groups in the decomposition of plant residues caused weight loss of larch-needles and root mortmass. Isolation of organic matter from all-size invertebrate groups leads to some decrease of decomposition activity. В© Springer 2006.

Аннотация: Methods for assessing the primary productivity of the forest stands between various tree species in different environmental conditions are considered. Methods for the primary productivity assessment using data on the phytomass fractions and stand wood stock have been proposed. It is shown that the Zipf-Pareto equation of the relationship between the phytomass of some tree fractions in the stand can be used for a primary productivity estimation of the stock volume. A model analogous to R. Solow's macroeconomic model has been proposed to describe the processes of the phytomass growth in the forest stand.

. - ISSN 0044-4596
Аннотация: Optimisation approach used to describe tree growth supposes the allocation of resources for different ecological and physiological functions: photosynthesis, absorption and transport of substances, wind protection, etc. The author suggests a theoretical model that describes the distribution of mass for tree fractions and compares the model and experimental measurements of biomass of different fractions. The distribution of biomass can be described with the Zipf-Pareto equation of free competition. The method to evaluate the root biomass using the data on above-ground biomass of tree is proposed. The relations of equations used to describe the free competition and allometric growth were studied. It was shown that allometric equations can be derived from the equation of free competition under some special conditions.

Lignin Microbial biomass -- Mineralization -- Non-cellulosic sugars -- Soil organic carbon quality
Аннотация: Background Meadows and shrublands are two major vegetation types on the Qinghai-Tibetan Plateau, but little is known about biochemical characteristics and its relation to decomposability of soil organic carbon (OC) under these two vegetation types. The present study was designed to evaluate effects of aspect-vegetation complex on biochemical characteristics and decomposability of soil OC. Methods Two hills were randomly selected; both with vegetation being naturally divided into southward meadows and northward shrublands by a ridge, and soils were sampled at depths of 0-15 and 15-30 cm, along contours traversing the meadow and shrubland sites. Particulate (particle size 2-0.05 mm) OC and nitrogen (N), microbial biomass C and N, non-cellulosic sugars, and CuO lignin were analyzed, and OC mineralization was measured for 49 days at 18 and 25 °C under laboratory incubation, respectively. Results More than half of soil OC was present as particulate fraction across all samples, indicating the coarse nature of soil organic matter in the region. Averaging over depths, shrublands contained 87.7 - 114.1 g OC and 7.7 - 9.3 g N per kg soil, which were 63 - 78 and 26 - 31 % higher than those in meadows, respectively. Meanwhile the C/N ratio of soil organic matter was 11.4 - 12.3 under shrublands, being 29 - 40 % higher than that under meadows. Soil OC under meadows was richer in noncellulosic carbohydrates and microbial biomass in the 0-15 and 15-30 cm depths but contained less lignin in the 15-30 cm depth. Ratios of microbially- to plant-derived monosaccharides and between acid and aldehyde of the vanillyl units were greater in soils under shrublands, showing more abundant microbially-derived sugars and microbially-transformed ligneous substances in OC as compared to meadow soils. By the end of 49 days' incubation, total CO2-C evolution from soils under meadows was 15.0-16.2 mg g-1 OC averaging over incubation temperatures and soil depths, being 27-55 % greater than that under shrublands. Across all soil samples over two sites, total CO2 - C evolved per g OC at either 18 or 25 °C was closely correlated to enrichments of noncellulosic carbohydrates and microbial biomass. This indicates that the greater soil OC decomposability under meadows was associated with its larger abundances of readily mineralizable fractions compared with shrublands. However, temperature increase effect on soil OC decomposability did not differ between the two types of vegetation. Conclusions Our findings suggest that the aspect-vegetation complex significantly affected pool size, biochemical characteristics, and decomposability of soil OC on the northeastern edge of Qinghai-Tibetan Plateau. However, the response of soil OC decomposability to temperature was similar between southward meadows and northward shrublands. © 2014 Springer International Publishing Switzerland.

Lignin deposition during earlywood and latewood formation in Scots pine stems
/ G. F. Antonova [et al.] // Wood Sci Technol. - 2014. - Vol. 48, Is. 5. - P. 919-936, DOI 10.1007/s00226-014-0650-3

Аннотация: Lignin deposition at consecutive secondary wall thickening stages of early and late xylem cells during annual ring wood formation in Scots pine (Pinus sylvestris L.) stems was studied. Lignin patterns, isolated by thioglycolic acid method, consisted of alcohol-soluble (LTGA-I) and alkali-soluble (LTGA-II) fractions. The sum of two fractions, being the total lignin content, gradually increased in the course of lignification. However, the increments of lignin amount at each development stage of early and late tracheids were different. The intensity of lignin deposition increased in the course of earlywood tracheid maturation and decreased toward the end of latewood cell differentiation. The deposition of two lignin fractions in each layer of forming wood also occurred oppositely. The increment of LTGA-I descended, whereas that of LTGA-II increased from the beginning to the end of early xylem lignification. In contrast, LTGA-I increment dropped, whereas LTGA-II rose during late xylem lignification. Gel permeation chromatography showed that the lignins, formed at the beginning of lignification, were more homogeneous and had higher molecular weight compared with the lignins at the end of cell differentiation. Besides, the content of cellulose, estimated as the residue after lignin isolation, and of cell wall substances, presented as cell wall cross-section areas, at consecutive maturation stages of early and late xylem cells have been found to be different. The data show that lignin deposition occurred in different conditions and with opposite dynamics during early and late xylem formation. © 2014 Springer-Verlag Berlin Heidelberg.
