Аннотация: Each tree ring contains an image of the time when the ring formed, projected onto the ring's size, structure, and composition. Tree rings thus are natural archives of past environments, and contain records of past climate. While dendrochronologists have investigated the impact of climate on tree-ring growth by empirical-statistical methods. This volume presents a process-based model complementing previous approaches. Basic ideas concerning the biology of tree-ring growth and its control by environmental factors are treated, especially for conifers. The use of the model is illustrated by means of several examples from widely differing environments, and possible future directions for model development and application are discussed. The volume provides an improved mechanistic basis for the interpretation of tree rings as records of past climate. It advances process understanding of the large-scale environmental control of wood growth. As forests are the main carbon sink on land, the results are of great importance for all global change studies.

Аннотация: This paper studies the structure and dynamics of the major pools of organic matter in clearings in the lichen pine forests of the middle taiga subzone of Yenisei Siberia, in the range of measurements of the international observatory Zotto, a high-tech research platform for long-term ( 30 years) monitoring of the atmosphere and climate changes. The contribution of phytocenoses at different stages of post-clearing succession in the process of deposition of atmospheric carbon is analyzed. In conjunction with the data on atmospheric measurements of a wide range of greenhouse gases carried out at the base of the observatory, the results of this work will be used for modeling the stocks and flows of carbon in forest ecosystems of Central Siberia.

Аннотация: Embryogenic callus formation in different larch species from Siberia (Larix sibirica, L. gmelinii, and L. sukaczewii) was carried out on MSGm medium supplemented with growth regulators (2.4-D and BAP) and followed one and the same scheme: elongation of somatic cells and their asymmetric division with formation of initial and tube cells. The cells of embryo initial underwent sequential divisions and formed embryonic globules which caused the formation of somatic embryos. Somatic embryos became mature and germinated by addition of ABA and PEG into the medium. Long-term proliferating cell lines and regenerant plants were obtained in Sukachev larch and its hybrid with Siberian larch. The success of somatic embryogenesis depended on the genotype of the donor tree.

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: 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: 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 stock and structure of organic substances in the pine tree plantations on the overburden dumps of open-cut coal mines in Middle Siberia have been determined. It has been shown that the forming forest biogeocenoses differ from the natural phytocenoses and soils of the forest landscapes in the structure of the carbon pool and its distribution between the vegetation and soil components. In artificial forest ecosystems, the bulk of the plant component is accumulated in the aboveground part of the forest stand (40-59%). The aboveground grass cover contains only 0.1-1.4% of the total phytomass stock of the ecosystem. The annual accumulation of organic substances in the initial soils amounts to 0.28-1.45 t/ha.

Аннотация: A spatial description of climatic changes along circumpolar regions is presented based on larch tree-ring width (TRW) index, latewood density (MXD), delta 13C, delta 18O of whole wood and cellulose chronologies from eastern Taimyr (TAY) and north-eastern Yakutia (YAK), Russia, for the period 1900-2006, in comparison with a delta 13C cellulose chronology from Finland (FIN) and a delta 18O ice core record from Greenland (GISP2). Correlation analysis showed a strong positive relationships between TRW, MXD, stable isotope chronologies and June, July air temperatures for TAY and YAK, while the precipitation signal was reflected differently in tree-ring parameters and stable isotope data for the studied sites. Negative correlations were found between July, August precipitation from TAY and stable isotopes and MXD, while May, July precipitations are reflected in MXD and stable isotopes for the YAK. No significant relationships were found between TRW and precipitation for TAY and YAK. The areas of significant correlations between July gridded temperatures and TRW, MXD and stable isotopes show widespread dimension from east to west for YAK and from north to south for TAY. The climate signal is stronger expressed in whole wood than in cellulose for both Siberian regions. The comparison analysis between delta 13C cellulose chronologies from FIN and TAY revealed a similar declining trend over recent decades, which could be explained by the physiological effect of the increasing atmospheric CO(2). TRW, MXD and delta 13C chronologies from TAY and YAK show a negative correlation with North Atlantic Oscillation index, while the delta 18O chronologies show positive correlations, confirming recent warming trend at high latitudes. The strong correlation between GISP2 and delta 18O of cellulose from YAK chronologies reflects the large-scale climatic signal connected by atmospheric circulation patterns expressed by precipitation.

Аннотация: The dynamics of organic matter accumulated in the soil and main vegetation elements was analyzed for post-logging forest ecosystem succession series in eastern Baikal region. The phytomass was found to allocate up 63 and 50% of carbon in undisturbed Scots pine and fir stands, respectively. The post-logging phytomass contribution to the total carbon pool appeared to decrease down to 16% in Scots pine and 6% in fir stands. In Scots pine stands, carbon storage was determined to account for almost 70% of the initial carbon 60 years after logging. In 50- to 55-year-old fir stands, carbon recovered its initial pool only by 10%. Soil carbon recorded in recently logged Scots pine and fir sites appeared to be 5 and 16 times that accumulated in the phytomass, respectively. The ratio between phytomass carbon and soil organic matter recovered back to the prelogging level in Scots pine stands by the age of 50-60 years. While phytomass carbon also increased in fir stand of the same age, it did not reach the level of the control stand.

Аннотация: The scaling of respiratory metabolism with body mass is one of the most pervasive phenomena in biology. Using a single allometric equation to characterize empirical scaling relationships and to evaluate alternative hypotheses about mechanisms has been controversial. We developed a method to directly measure respiration of 271 whole plants, spanning nine orders of magnitude in body mass, from small seedlings to large trees, and from tropical to boreal ecosystems. Our measurements include the roots, which have often been ignored. Rather than a single power-law relationship, our data are fit by a biphasic, mixed-power function. The allometric exponent varies continuously from 1 in the smallest plants to 3/4 in larger saplings and trees. Therefore, our findings support the recent findings of Reich et al. [Reich PB, Tjoelker MG, Machado JL, Oleksyn J (2006) Universal scaling of respiratory metabolism, size, and nitrogen in plants. Nature 439: 457-461] and West, Brown, and Enquist [West GB, Brown JH, Enquist BJ (1997) A general model for the origin of allometric scaling laws in biology. Science 276: 122 - 126.]. The transition from linear to 3/4-power scaling may indicate fundamental physical and physiological constraints on the allocation of plant biomass between photosynthetic and nonphotosynthetic organs over the course of ontogenetic plant growth.

Аннотация: Estimates of past climate and future forest biomass dynamics are constrained by uncertainties in the relationships between growth and climatic variability and uncertainties in the instrumental data themselves. Of particular interest in this regard is the boreal-forest zone, where radial growth has historically been closely connected with temperature variability, but various lines of evidence have indicated a decoupling since about the 1960s. We here address this growth-vs.-temperature divergence by analyzing tree-ring width and density data from across Siberia, and comparing 20th century proxy trends with those derived from instrumental stations. We test the influence of approaches considered in the recent literature on the divergence phenomenon (DP), including effects of tree-ring standardization and calibration period, and explore instrumental uncertainties by employing both adjusted and nonadjusted temperature data to assess growth-climate agreement. Results indicate that common methodological and data usage decisions alter 20th century growth and temperature trends in a way that can easily explain the post-1960 DP. We show that (i) Siberian station temperature adjustments were up to 1.3 degrees C for decadal means before 1940, (ii) tree-ring detrending effects in the order of 0.6-0.8 degrees C, and (iii) calibration uncertainties up to about 0.4 degrees C over the past 110 years. Despite these large uncertainties, instrumental and tree growth estimates for the entire 20th century warming interval match each other, to a degree previously not recognized, when care is taken to preserve long-term trends in the tree-ring data. We further show that careful examination of early temperature data and calibration of proxy timeseries over the full period of overlap with instrumental data are both necessary to properly estimate 20th century long-term changes and to avoid erroneous detection of post-1960 divergence.

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: Terrestrial ecosystems in northern high latitudes exchange large amounts of methane (CH4) with the atmosphere. Climate warming could have a great impact on CH4 exchange, in particular in regions where degradation of permafrost is induced. In order to improve the understanding of the present and future methane dynamics in permafrost regions, we studied CH4 fluxes of typical landscape structures in a small catchment in the forest tundra ecotone in northern Siberia. Gas fluxes were measured using a closed-chamber technique from August to November 2003 and from August 2006 to July 2007 on tree-covered mineral soils with and without permafrost, on a frozen bog plateau, and on a thermokarst pond. For areal integration of the CH4 fluxes, we combined field observations and classification of functional landscape structures based on a high-resolution Quickbird satellite image. All mineral soils were net sinks of atmospheric CH4. The magnitude of annual CH4 uptake was higher for soils without permafrost (1.19 kg CH4 ha(-1) yr(-1)) than for soils with permafrost (0.37 kg CH4 ha(-1) yr(-1)). In well-drained soils, significant CH4 uptake occurred even after the onset of ground frost. Bog plateaux, which stored large amounts of frozen organic carbon, were also a net sink of atmospheric CH4 (0.38 kg CH4 ha(-1) yr(-1)). Thermokarst ponds, which developed from permafrost collapse in bog plateaux, were hot spots of CH4 emission (approximately 200 kg CH4 ha(-1) yr(-1)). Despite the low area coverage of thermokarst ponds (only 2.1% of the total catchment area), emissions from these sites resulted in a mean catchment CH4 emission of 3.8 kg CH4 ha(-1) yr(-1). Export of dissolved CH4 with stream water was insignificant. The results suggest that mineral soils and bog plateaux in this region will respond differently to increasing temperatures and associated permafrost degradation. Net uptake of atmospheric CH4 in mineral soils is expected to gradually increase with increasing active layer depth and soil drainage. Changes in bog plateaux will probably be much more rapid and drastic. Permafrost collapse in frozen bog plateaux would result in high CH4 emissions that act as positive feedback to climate warming.

Аннотация: The abundance distribution of different ecological groups of lichens depending on bark pH has been studied on 1- to 24-year shoots of Siberian fir in the mountains of southern Siberia. Along with acidophytic lichens commonly found on the Siberian fir (Usnea sp., Bryoria sp., etc.), its young shoots are also colonized by nitrophytic species (Physcia tenella, Melanelia exasperatula, etc.), which is evidence for the increasing pH of shoot bark. The proportion of thalli of nitrophytic lichen species shows a significant positive correlation with the pH of the upper (dusted) bark layer and is greater in the Eastern Sayan (at bark pH averaging 5.4) than in the Western Sayan (pH 4.7). The trends revealed in this study may be used for indication of pollution and ecological monitoring of forest ecosystems.

Аннотация: The seasonal development of phloem in the stems of Siberian larch (Larix sibirica Ldb.) was studied over two seasons on 50-60-year-old trees growing in a natural stand in the Siberian forest-steppe zone. Trees at the age of 20-25 years were used to study metabolites in differentiating and mature phloem elements, cambial zone, and radially growing xylem cells in the periods of early and late wood formation. The development of the current-year phloem in the stems of 50-60-year-old trees started, depending on climatic conditions, in the second-third decades of May, 10-20 days before the xylem formation, and ended together with the shoot growth cessation in late July. Monitoring of the seasonal activity of cambium producing phloem sieve cells and the duration of their differentiation compared to the xylem derivatives in the cambium demonstrated that the top production of phloem and xylem cells could coincide or not coincide during the season, while their differentiation activity was always in antiphase. Sieve cells in the early phloem are separated from those in the late phloem by a layer of tannin-containing cells, which are formed in the period when late xylem formation starts. The starch content in the structural elements of phloem depends on the state of annual xylem layer development. The content of low molecular weight carbohydrates, amino acids, organic acids, and phenols in phloem cells, cambial zone, and xylem derivatives of the cambium depends on the cell type and developmental stage as well as on the type of forming wood (early or late) differing by the cell wall parameters and, hence, by the requirement for assimilates. Significant differences in the dynamics of substances per dry weight and cell were observed during cell development.
