Аннотация: The increasing of burning area in Siberia, the extension of fire season and fires intensity lead to significant carbon emission. One of the important tasks is to describe the spread of smoke aerosol and other combustion products using actual meteorological data and fire state information. A smoke aerosol covers territory hundreds times larger than the burning area and has an effect on forming the cloud and sediment formation exactly above the fire zone.

Аннотация: Variability of soil CO2 efflux strongly depends on soil temperature, soil moisture and plant phenology. Separating the effects of these factors is critical to understand the belowground carbon dynamics of forest ecosystem. In Ethiopia with its unreliable seasonal rainfall, variability of soil CO2 efflux may be particularly associated with seasonal variation. In this study, soil respiration was measured in nine plots under the canopies of three indigenous trees (Croton macrostachys, Podocarpus falcatus and Prunus africana) growing in an Afromontane forest of south-eastern Ethiopia. Our objectives were to investigate seasonal and diurnal variation in soil CO2 flux rate as a function of soil temperature and soil moisture, and to investigate the impact of tree species composition on soil respiration. Results showed that soil respiration displayed strong seasonal patterns, being lower during dry periods and higher during wet periods. The dependence of soil respiration on soil moisture under the three tree species explained about 50% of the seasonal variability. The relation followed a Gaussian function, and indicated a decrease in soil respiration at soil volumetric water contents exceeding a threshold of about 30%. Under more moist conditions soil respiration is tentatively limited by low oxygen supply. On a diurnal basis temperature dependency was observed, but not during dry periods when plant and soil microbial activities were restrained by moisture deficiency. Tree species influenced soil respiration, and there was a significant interaction effect of tree species and soil moisture on soil CO2 efflux variability. During wet (and cloudy) period, when shade tolerant late successional P. falcatus is having a physiological advantage, soil respiration under this tree species exceeded that under the other two species. In contrast, soil CO2 efflux rates under light demanding pioneer C. macrostachys appeared to be least sensitive to dry (but sunny) conditions. This is probably related to the relatively higher carbon assimilation rates and associated root respiration. We conclude that besides the anticipated changes in precipitation pattern in Ethiopia any anthropogenic disturbance fostering the pioneer species may alter the future ecosystem carbon balance by its impact on soil respiration.

Аннотация: Soils in the tree nurseries studied were characterized by a lower species diversity of fungi than adjacent virgin soils. In particular, the relative abundances of representatives of the genera Mucor Chaetomium, and Trichoderma in the nursery soil were two times lower than in adjacent virgin soils. On the other hand, the nursery soil exhibited greater abundances of fungi of the genus Fusarium, which are causative agents of many diseases of conifer seedlings. To appreciate the efficiency of biocontrol of the infectious diseases of conifer seedlings, we introduced several indigenous Trichoderma strains into the nursery soil and found that this affected the species composition of soil microflora considerably. Changes in the species composition of mycobiota beneficially influenced the phytosanitary state of soils and reduced the infectious lodging of conifer seedlings.

Аннотация: The development of certain form depends on natural selection and morphogenesis. The former process is resulted in analogies - characters of convergent similarity, while the latter can lead to non-adaptive parallel similarity of relatives (homologous series of N.I. Vavilov). Morphogenetic factor is shaped by past selection but does not depend on it at each new evolution act: spectrum of forms that can be produced is totally determined by embryological mechanisms and precedes the beginning of an evolutionary change. Mutual independence of two factors allows to use Bohr's correspondence principle. According to this principle any explanation is not full: it has its own competence area with its own rules for conclusions; there is no rules for logic transition between groups of accidental events; interaction of factors is expressed only as a limitation of their pattern formation abilities. To diminish uncertainty one can use the principle of evolution stabilisation of function by N.V. Kokshaisky, i.e. statement that functions of organism level are kept stable in the process of evolution while some changes at the lower levels are possible. The higher level of changes, the more complete reconstruction takes place in organism. The direction of evolution is minimisation of total sum of changes. As a consequence, the higher hierarchical level of function, more adaptive characters are belonged to its structures. And opposite, the lower hierarchical level, the more freedom for morphogenetic changes, the form of structures becomes indifferent for selection. Therefore the characters of high hierarchical levels can be explained in terms of adaptation, while the features of low level - on the base of morphogenetic peculiarities.

Аннотация: The authors consider three interaction models ''resource - consumer''. ''Null model'' is basic for the rest ones because in its frame the antibiosis of feeding objects does not take into consideration. According to reparation model feeding objects be either accessible for consumption or exist in reparation state if the high concentration of protection substances does not allow the population of consumers to continue feeding. Complicated model includes three states of feeding object: it is accessible and not attacked by insects, it is accessible and attacked and feeding object exists in reparation state. This model takes into consideration a set of different effects, for instance the effect of slow development of reparation processes. The changes taking place under pollution influence with different parameters of ''resource - consumer''interaction are characterised. The authors suggest the classification of different ''resource - consumer'' models based on resource characters. All models show the exponential decrease in the portion of non-damaged feeding objects while they contact with consumers. Change of this portion allows to measure the rate of consumer attack, whereas the dynamic of total number of damages characterizes the reparation characteristics. The authors investigate the damage of Populus leaves by insects in plots situated in Krasnoyarsk in regions with different antropogenic influence. The dynamic of damages shows the high degree of consent with the models. They can be useful for entomological indication to evaluate the state of separate trees or the whole stand.

Аннотация: This study was carried out to investigate the interaction between basidiomycetes and Ophiostomataceae fungi that were able to inhibit the growth of blue stain fungi and to decolorize its dark pigments. Twenty-eight isolates belonging to 18 species of basidiomycetes and eighteen isolates of 11 blue stain fungi, mainly from Ophiostomataceae family, were used. The dual culture technique was adopted to study the interaction between basidial and blue stain fungi isolates. The ability of basidial cultures to decolourize dark pigments of ophiostomatoid fungi was the main characteristics estimated during this investigation. Antrodiella hoehnelii (S28/91), Bjerkandera fumosa (137), Gleophyllum odoratum (124), and Trametes versicolor (1318/91) cultures were found to be the most active in decreasing dark colour of blue stain fungi colonies. The cultures were recommended for further development as agents of biopulping and control of blue stain fungi in wood chips.

Аннотация: The periodic production of large seed crops by trees (masting) and its interaction with stern growth has long been the objective of tree physiology research. However, very little is known about the effects of masting on stern growth and total net primary productivity (NPP) at the stand scale. This study was conducted in an old-growth, mixed deciduous forest dominated by Fagus sylvatica (L.) and covers the period from 2003 to 2007, which comprised wet, dry and regular years as well as two masts of Fagus and one mast of the co-dominant tree species Fraxinus excelsior (L.) and Acer pseudoplatanus (L.). We combined analyses of weather conditions and stem growth at the tree level (inter- and intra-annual) with fruit, stem and leaf production, and estimates of total NPP at the stand level. Finally, we compared the annual demand of carbon for biomass production with net canopy assimilation (NCA), derived from eddy covariance flux measurements, chamber measurements and modelling. Annual stem growth of Fagus was most favoured by warm periods in spring and that of Fraxinus by high precipitation in June. For stem growth of Acer and for fruit production, no significant relationships with mean weather conditions were found. Intra-annual stem growth of all species was strongly reduced when the relative plant-available water in soil dropped below a threshold of about 60% between May and July. The inter-annual variations of NCA, total NPP and leaf NPP at the stand level were low (mean values 1313, 662 and 168 g C m(-2) year(-1), respectively), while wood and fruit production varied more and contrarily (wood: 169-241 g C m(-2) year(-1); fruits: 21-142 g C m(-2) year(-1)). In all years, an annual surplus of newly assimilated carbon was calculated (on average 100 g C m(-2) year(-1)). The results suggest that stem growth is generally not limited by insufficient carbon resources; only in mast years a short-term carbon shortage may occur in spring. In contrast to common assumption, stem growth alone is not a sufficient proxy for total biomass production or the control of carbon sequestration by weather extremes.

Аннотация: Natural and human-induced changes in the composition of boreal forests will likely alter soil properties, but predicting these effects requires a better understanding of how individual forest species alter soils. We show that 30 years of experimental afforestation in Siberia caused species-specific changes in soil chemical properties, including pH, DOC, DON, Na+,NH4+, total C, C/N, Mn2+, and SO42-. Some of these properties-pH, total C, C/N, DOC, DON, Na+-also differed by soil depth, but we found no strong evidence for species-dependent effects on vertical differentiation of soil properties (i.e., no species x depth interaction). A number of soil properties-NO3-, N, Al3+, Ca2+, Fe3+, K+, Mg2+ and Cl- -responded to neither species nor depth. The six studied species may be clustered into three groups based on their effects on the soil properties. Scots pine and spruce had the lowest pH, highest C/N ratio and intermediate C content in soil. The other two coniferous species, Arolla pine and larch, had the highest soil C contents, highest pH values, and intermediate C/N ratios. Finally, the two deciduous hardwood species, aspen and birch, had the lowest C/N ratio, intermediate pH values, and lowest C content. These tree-mediated soil chemical changes are important for their likely effects on soil microbiological activities, including C and N mineralization and the production and consumption of greenhouse gases.

Аннотация: The analysis of the anatomical characteristics of tree rings of the Pinus sibirica scions and Pinus sylvestris rootstocks is presented. The main anatomical features maintain the seasonal dynamics characteristic of the reference (ungrafted) trees of scion and rootstock, pointing to the stability of the genetic control of the xylem differentiation. However, various anatomical characteristics are reduced for rootstocks and increased for scions relative to the reference trees. A mechanism consistent with our results is that the graft union zone creates a barrier for the ascending and descending transport of substances, including phytohormones. The reaction of the scion and rootstock to climatic factors is weakened relative to the reaction of the reference trees. Thus, the presumed shift towards phytohormone disbalance reduces the influence of external factors on xylem differentiation. The interannual variation of the individual characteristics of the scions and rootstocks is increased relative to the reference trees, reflecting either the influence of the graft partners on each other or the non-uniform distribution of the growth regulators across the graft union. Thus, heterografts can be used to evaluate the interaction of the internal and external mechanisms of xylem differentiation.

Аннотация: The Siberian moth, Dendrolimus sibiricus, Tschtv. is the most harmful defoliator of coniferous forests in North Asia. The pest has already spread over the Urals and continues moving westwards. Recently, it has been recommended for quarantine in member countries by European and Mediterranean Plant Protection Organization (EPPO). The performances of the pest on coniferous species planted in Europe were assessed on a range of potted trees corresponding to the spectrum of economically important conifers in the EU: European larch Larix decidua, Norway spruce Picea abies, Scots pine Pinus sylvestris, European black pine Pinus nigra, and the North American species: Douglas fir Pseudotsuga menziesii and grand fir Abies grandis. Larvae showed a potential to survive and complete the development on all these host tree species. Favorable hosts were grand fir, European larch, and Douglas fir that allowed higher survival, better larval development, and as a result, yielded heavier pupae and adult moths with higher longevity. Black pine was a poor host but, however, could still support larval and pupal development. Norway spruce and Scots pine had an intermediate behavior. If accidentally introduced to Europe, the Siberian moth may become especially damaging in forest stands predominated by European larch and by the North American firs. Norway spruce and especially the two-needle pines will be less prone to intensive defoliation by this species. The fact that the pest may damage the range of economically important coniferous species should be taken into account in the pest risk assessment for Europe and also for North America where the Siberian moth occurrence is considered likely.

Аннотация: Energy and latent heat fluxes ?E were measured over ombrotrophic bogs in European Russia (Fyodorovskoye) and in central Siberia (Zotino) using the eddy covariance technique, as part of the EuroSiberian Carbonflux Project. The study covered most of the snowfree periods in 1998, 1999 and 2000; in addition some data were also collected under snow in early spring and late autumn 1999 and 2000. The snowfree period in Europian Russia exceeds the snowfree period in central Siberia by nearly 10 weeks. Marked seasonal and interannual differences in temperatures and precipitation, and hence energy partitioning, were observed at both sites. At both bogs latent heat fluxes (?E) exceeded sensible heat fluxes (H) during most of the snowfree period: maximum ?E were between 10 and 12 MJ m -2 d -1 while maximum H were between 3 and 5 MJ m -2 d -1. There was a tendency towards higher Bowen ratios at Fyodorovskoye. Net radiation was the most influential variable that regulated daily evaporation rates, with no obvious effects due to surface dryness during years with exceptionally dry summers. Total snowfree evaporation at Fyodorovskoye (320 mm) exceeded totals at Zotino (280 mm) by 15%. At the former site, evaporation was equal to or less than precipitation, contrasting the Zotino observations, where summer evaporation was distinctly higher than precipitation. During the entire observation period evaporation rates were less than 50% of their potential rate. These data suggest a strong 'mulching' effect of a rapidly drying peat surface on total evaporation, despite the substantial area of free water surfaces during parts of the year. This effect of surface dryness was also observed as close atmospheric coupling.

Аннотация: The interaction of β-meteoroids with the Earth's magnetosphere is considered within the "dust plasma" ensemble framework. This interaction is shown to result in variations of the charge of micrometeoroids and in change of their dynamics. This leads to formation of a dust flux in the magnetoshock tail, directed towards the ionosphere, and dust fluxes directed towards the Earth apex (antiapex), with a density exceeding background.

Аннотация: The flame spread limit moisture content wl of fallen pine needles was investigated in a centrifuge. The wl value was found to decrease with increasing gravitational forces and with increasing air flow velocity ?f when flame spread and centrifuge rotation directions coincided. The wl(?f) dependence had a maximum in the region of low air flow velocities when the above directions were opposite. The limit moisture content was established to be a function of particle slope angle, particle diameter, and its composition. It was also found that the limit flame spread rate depends strongly on burning conditions. The mathematical model of limit phenomena has been worked out on the basis of the heat theory of diffusion flame extinction by describing the flame spread process along plant particles as the result of interaction between a point source of flammable gases and the surrounding air flow. By comparing the experimental data with the mathematical model, gravitational forces were shown to influence the extinction limit by increasing the velocity of air flow which arises around the flame through buoyancy forces. Also it was shown that extinction by gravitational forces and by air flow occurred mainly due to increasing convective heat loss rate from the flame reaction surface to the surrounding air. В© 1982.

Аннотация: I examine the cellular basis of tree-ring formation and the peculiarities of seasonal growth, and try to systematize the mechanisms that regulate the formation of conifer tree-ring structure. In addition to tree-ring width, some other anatomical data are increasingly being used in dendrochronology, namely cell size and wood density. I attempt to present a conceptual scheme of interaction of processes of xylem cell maturation. This scheme includes external regulation and is adequate for formalization in the form of a simulation model.

Аннотация: The spatial structure of complex forest stands results from competitive interactions among trees which is one of the most important ecological processes influencing forest development. The aim of the study is to incorporate in a new class of random point process models a coherent representation of the competition process driving forest stand dynamics to establish a direct link between pattern and ecological processes. The resulting area-saturation model was defined by a set statistic characterised by overlapping discs representing tree interactions. Unlike previous approaches, this new spatial model has the advantage of allowing a straightforward interpretation of its parameters in terms of inter-tree competition. A 60. m. ?. 60. m plot of even-aged Scots pines was used to illustrate the potential of this approach in modelling the spatial structure of a plant community. The social status of each tree was taken into account, leading to a multivariate point pattern exhibiting various spatial properties (regularity, clustering and randomness) at different scales. We considered a hierarchical structure of interactions to account for the fact that competition for light is size-asymmetric. According to the analysis, the generalised area-saturation model has the required flexibility to capture complex spatial tree patterns. © 2014 Elsevier B.V.

Аннотация: Seasonal dynamics of CO2 efflux from gray forest soil have been studied using collars inserted to different depths in order to estimate the contributions and interaction of soil autotrophs and heterotrophs. The depth of collar insertion has proved to have an effect on CO2 efflux only in periods of the highest biological activity. It has also been shown for the first time that the level of competition between soil autotrophs and heterotrophs depends mainly on tree species rather than on soil type.

Аннотация: Effect of high pressure induced spin crossover on the magnetic, electronic and structural properties of the minerals forming the Earth's low mantle is discussed. The low temperature P, T phase diagram of ferropericlase has the quantum phase transition point P = 56 GPa at T = 0 confirmed recently by the synchrotron Mossbauer spectroscopy. The LDA+GTB calculated phase diagram describes the experimental data. Its extension to the high temperature resulted earlier in prediction of the metallic properties of the Earth's mantle at the depth 1400 km h 1800 km. Estimation of the electrical conductivity based on the percolation theory is given. We discuss also the thermodynamic properties and structural anomalies resulting from the spin crossover and metal insulator transition and compare them with the experimental seismic and geomagnetic field data.
