Аннотация: Four birch species are traditionally used for the sap harvesting in Russia. In the report, we discuss their spatial and ecophysiological features as well as the exudation, tapping periods and sap productivity. Biochemical constituents of the living tissues of the birches such as the wood, outer and inner bark, twigs, leaves, buds, roots, and exudated birch sap are also reviewed. We show numerous useful wooden, medicinal, tanning, coloring as well as feeding and decorative properties. Chaga - a fungi-parasite developed on the stems of the birch trees, is mentioned to be famous due to its antitumor and/or especially anti-cancer activity. It is reported that the former birch sap production closed completely at the transition to a market-economy has restarted in the Russian Far East.

Biochemistry of carbon and nitrogen in the Siberian Afforestation Experiment
: материалы временных коллективов / E. F. Vedrova // Tree species effects on soils: implications for global change. - 2005. - С. 281-292. - Библиогр. в конце ст.
Аннотация: We evaluated parameters (stock and flux) carbon, nitrogen and ash element cycling in the plant-soil system. The study was performed in arolla pine, Scots pine, Siberian larch, Norway spruce, aspen and birch plantations established on Kemchug upland, Chulym-Yenisei denudational plain, in 1968-1972. Young ecosystems (age class 2) that have developed under relatively similar environmental conditions have thus accumulated different amounts of organic and mineral matter in biomass and detritus, mainly due to differences in major woody species characteristics. All ecosystems are a net atmosperic carbon sink, with a pooling rate of 1.81-4.43 t C ha -1 yr -1. The sink (NEP) is made up by C accumulation in stand biomass production, vegetation detritus, and soil humus and accounts for 46-76% of the total C allocated in annual increment; the main componentt is net C flux to biomass. The rate of N-min flux from soil pool to NPP is in fact in balance with that soil N-min accumulation in the arolla pine, larch, spruce, and birch plots. In addition, the ecosystems are characterized by a transitional cycling regime evident through non-balanced controlling organic and mineral matter stored in "plant-soil" system blocks.

The formation of soil invertebrate communities in the Siberian Afforestation Experiment
: материалы временных коллективов / I. N. Bezkorovaynaya // Tree species effects on soils: implications for global change. - 2005. - С. 307-316. - Библиогр. в конце ст.
Аннотация: An estimation of formation of soil invertebrate complexes was carried out on a common-garden provenance test with major Siberian woody species: arolla pine, Scots pine, Siberian larch, Norway spruce, birch, and aspen. The experiment was established on a former agricultural field, so the formation of soil communities over 30 year period combined the effects of both the reestablishment of forest conditions for soil formation and the influence of each tree species.

The transformation of plant residues under different tree species in the Siberian Afforestation Experiment
: материалы временных коллективов / L. V. Mukhortova // Tree species effects on soils: implications for global change. - 2005. - С. 316-336. - Библиогр. в конце ст.
Аннотация: The forest floor (O horizon) is a major pool of organic matter in many forests, comprised of a wide range of materials that vary in chemistry and morphology. The processing of fresh detritus progresses with gradual degradation under the influence of biotic and abiotic factors, leading to decreasing particle size and carbon:nitrogen ratios. The carbon contained in annual litterfall inputs equaled 20- 26% of the totral forest floor C content in conifer plots, compared with 48 to 55% in the aspen and birch plots. This material remains in the O1 layer for 2 to 12 months. The Of layer comprises 47 to 85% of the total C content of the forest floor, with residence times of 0.5 to 5 years.

Carbon pools and fluxes of 25-year old coniferous and deciduous stands in Middle Siberia
: материалы временных коллективов / E. F. Vedrova // Water, air & soil pollution. - 1995. - Vol. 82, № 1-2. - С. 239-246. - Библиогр. в конце ст.
Аннотация: Between 72 and 88% of carbon (C) loss in forest litter decomposition returns to the atmosphere in the form of carbon dioxide. The share of water-soluble organic products does not exceed 3-4%. Between 8% under spruce and 25% under aspen and pine of the total C loss from litter organic matter goes to the formation of humus. Decomposition intensity of the dead organic matter on the soil surface is close to annual litterfall income (except under cedar). The specific rate of decomposition processes among the coniferous litters is minimum for cedar (167 mg C g-1 yr-1) and maximum for larch (249 mg C-1 yr-1). The spicific rate of decomposition of organic residues under aspen and birch canopies are 344 and 362 mg C-1 yr-1.

Nitrogen dynamics in leaves of deciduous broad-leaved tree seedlings grown in summer green forests in Northern Japan
: материалы временных коллективов / K. Takayoshi, K. Satoshi, O. V. Masyagina // Eurasian Journal of Forest Research. - 2007. - Vol. 10-1. - С. 115-119. - Библиогр. в конце ст.
Аннотация: Dynamics of nitrogen in leaves of trees and seedlings of deciduous broad-leaf species were studied for improving forest management. The photosynthetic traits of canopy leaves of diciduous broad-leaved trees were measured using a canopy tower. There was a clear positive correlation between leaf nitrogen content and light saturated photosynthetic rate at sunny canopy. As reflecting the shoot development pattern, leaf senescence began from the inner part of the crown in early successional species, by contrast leaf senescence process commences from either the outer or top portion of the crown in late successional species. For regenerated seedlings in forest floor, seasonal change in the allocation pattern of leaf nitrogen coincided with the changing of light conditions through the leaf phenology of upper canopy. In light limited condition, nitrogen was allocated to chlorophyll while it allocated to more to photosynthetic carbon fixation, i.e. Rubisco in strong light condition. Nitrogen allocated was affected more by light to CO2 condition that was found in birch and beech seedlings with a FACE system.

Evidence of evergreen conifers invasion into larch dominated forests during recent decades

Аннотация: The results obtained indicate a DNC and birch invasion into a traditional larch domination zone, and the connection of this phenomenon with climatic trends during last decades. On the western and southern margions DNC regeneration formed a second layer in the forest canopies, which could eventually replace the larch in the overstory. Larch as a species also responds to climatic trends: its radial increment significantly increased during last 3 decades, and this increase correlates with summer temperatures and precipitation. The other larch response is the migration into the trundra zone and a crown closure increase, as was found on the key-sites "Polar Ural"and "Ary-Mas". The resulting effect of this process may be that larch could reach the Arctic shore, a phenomenon that has happened in a former epoch, whereas the traditional area of larch dominance will turn to mixed taiga forest.

Аннотация: The total environmental damage induced by pollution by smoke from wildfires is difficult to evaluate even roughly. This is partly due to insufficient data on smoke pollution, which is in turn attributed to unsufficient or even lacking estimated data composition and amounts of emissions from wildfires. Laboratory analysis of smoke producing capability (SPC), or smoke production coefficient would enable to make compilation of a comprehensive database of negative impacts smoke emission of wildfire. Our study showed that for boreal Siberian species the greatest SPC produced birch bark (Betula).

swamp -- peat deposit -- pollen analysis -- climate and vegetation reconstruction -- forest cover dynamics -- Holocene
Аннотация: A reconstruction of forest-cover dynamics in the northern part of the Kas River basin has been done for the first time. This study based on a palynological analysis of the peat profile. Six pollen zones and respective phases of forest evolution are distinguished. It is inferred that changes in the forest species composition over the last 8000 years were determined by variations in the global and regional climate. The warm and humid climate of the Atlantic period promoted the development of dark coniferous birch-spruce-fir forests. Cooling and smaller precipitation in the Subboreal period led to a change in dominant species to Scotch pine and birch-Siberian pine forests with an admixture of spruce and fir. In the Subatlantic period, closed coniferous forests eventually evolved, with Siberian pine-pine remaining dominant.

Аннотация: The Trans-Baikal (or Zabailkal'e) region includes the forest-steppe ecotones south and east of Lake Baikal in Russia and has experienced drought for several years. The decline and mortality of birch (Betula pendula) stands within the forest-steppe ecotone Trans-Baikal region was studied based on a temporal series of satellite data, ground measurements, and tree ring analysis. During the first decade of the 21st century birch stands decline and mortality were observed on about 5% of the total area of stands within our 1250 km(2) study area. Birch forest decline and mortality occurs mainly at the margins of stands, within the forest-steppe ecotone on slopes with direct insolation. During the first decade of the 21st century summer (June-August) precipitation was about 25% below normal. Soil water content measurements were lowest within dead stands and highest within healthy stands and intermediate within damaged stands. Drought impact on stands was amplified by an increase in summer air temperatures (+0.9 degrees C) in comparison with the previous decade. Tree ring data of "surviving" and "dead" tree groups showed a positive correlation with summer/annual precipitation and negative correlation with summer air temperatures. Temperature and precipitation extreme anomalies tend to occur in the region with a period of about 27 years. The observed anomaly was the most severe since the beginning of meteorological observations in the year 1900. Data for the other sites showed a positive climate impact on the growth and expansion of Siberian forests. That is, the same species (B. pendula) showed considerable increase (1.4 times both in height and stem volume) during 20th-21st centuries as temperature increased but precipitation remained at adequate levels.

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.

Uses of tree saps in northern and eastern parts of Europe

Аннотация: In this article we review the use of tree saps in northern and eastern Europe. Published accounts by travellers, ethnologists and ethnobotanists were searched for historical and contemporary details. Field observations made by the authors have also been used. The presented data shows that the use of tree sap has occurred in most north and eastern European countries. It can be assumed that tree saps were most used where there were extensive stands of birch or maple trees, as these two genera generally produce the largest amount of sap. The taxa most commonly used have been Betula pendula, B. pubescens, and Acer platanoides, but scattered data on the use of several other taxa are presented. Tree sap was used as a fresh drink, but also as an ingredient in food and beverages. It was also fermented to make light alcoholic products like ale and wine. Other folk uses of tree saps vary from supplementary nutrition in the form of sugar, minerals and vitamins, to cosmetic applications for skin and hair and folk medicinal use. Russia, Ukraine, Belarus, Estonia, Latvia and Lithuania are the only countries where the gathering and use of sap (mainly birch sap) has remained an important activity until recently, due to the existence of large birch forests, low population density and the incorporation of sap into the former Soviet economic system. It is evident that gathering sap from birch and other trees was more widespread in earlier times. There are records indicating extensive use of tree saps from Scandinavia, Poland, Slovakia and Romania, but it is primarily of a historical character. The extraction of tree sap in these countries is nowadays viewed as a curiosity carried out only by a few individuals. However, tree saps have been regaining popularity in urban settings through niche trading.

Аннотация: The ash stock in forest litter influences the fertility of forest soil and should be studied. Litter samples were taken at 70 locations within a 270x60 metre transect in 2004-2007 in the bog birch forest, western Siberia. A geostatistical model with external trend was applied to describe the spatial pattern of the ash mass (kg m(-2)) on the forest floor. Hydrological factors, used as explanatory variables in an external trend equation, account for the main portion of spatial variation (83% and 49% in the years of, respectively, low and high spring flooding). Covariance structure of the data, connected with patterns of vegetation and silt deposits, explains the smaller portion of spatial variation (12% and 38%). The unexplained variation is minor (5% and 13%). (c) 2010 Published by Elsevier Ltd. Selection and/or peer-review under responsibility of Spatial Statistics 2011

Аннотация: A formalized arrangement of morphogenetic types of litter according to the physicochemical parameters provided their significant grouping in three genetic associations. The litter group (highly decomposed + moderately decomposed) is confined to the tall-grass group of bog birch forests. The rhizomatous (roughly decomposed) litter is formed in the sedge-reed grass bog birch forests. The litter group (peaty + peatified + peat) is associated with the bog-herbaceous-moss group of forest types. The genetic associations of the litters (a) reliably characterize the edaphic conditions of bog birch forests and (b)correspond to formation of the peat of certain ecological groups. We found highly informative the acid-base parameters, the exchangeable cations (Ca(2+) + Mg(2+)) and the total potential acidity, which differentiated the genetic associations of litter practically with 100% probability. The expediency of studying litters under groups of forest types rather than under separate types of bog birch forests was demonstrated.

Аннотация: The estimates of the carbon pool in the organic matter of gray soils of the southern taiga, the intensity of destruction of its components, and participation of the latter in the formation of the mineralized carbon flux to the atmosphere are presented for different stages of succession of deciduous (birch) and coniferous (fir) forests. The carbon pool varies from 139.7 to 292.7 t/ha. It is distributed between phytodetritus, mobile and stabile humus (32, 19, and 49%, respectively). The intensity of the mineralization carbon flux to the atmosphere amounts to 3.93-4.13 t C per year. Phytodetritus plays the main role in the formation of this flux. In the soils under the forests studied, 4-6% of the carbon flux are formed owing to mineralization of the newly formed soil humus. In birch forests, 2-6% (0.1-0.2% of the humus pool in the 0-20-cm layer) is the contribution to the flux due to mineralization of soil humus. In fir forests, the mineralized humus is compensated by humus substances synthesized in the process of humification during phytodetritus decomposition.

Аннотация: На градиенте крупнотравные – сфагново-мертвопокровные болотные березняки выделено шесть морфогенетических типов лесной подстилки: сильноразложившаяся, среднеразложившаяся, корневищная (груборазложившаяся), торфянистая, оторфованная и торфяная. Специфика их биохимической трансформации обусловлена величиной накопления гуминовых кислот преимущественно 1-й фракции на фоне относительно равномерной скорости формирования фульвокислот. Интенсивность образования ГК-1 тесно положительно связана с биологической активностью субстрата, судя по C/N. Однако нечеткие различия этих показателей в лесоводственно-морфологических типах подстилок ограничивают их диагностическую надежность. Сгруппированные биохимические категории подстилок – мягкие (среднеи сильноразложившиеся), переходные (корневищная, торфянистая, оторфованная) и грубые (моховая) – высокозначимо дискриминируются как отношением C/N – 20, 30, 40, так и содержанием ГК-1 – 14, 10, 6 % соответственно.
