Аннотация: The relationship between a physiological index called the photochemical reflectance index (PRI) and photosynthetic light-use-efficiency (LUE) of a Siberian boreal forest during the winter-spring transition, or green-up period, was investigated in 2000. During this time the photosynthetic apparatus was considered under stress as a result of extremes of temperature (from -20 to 35 degreesC) coupled with a high radiation load. Reflectance measurements of four stands were made from a helicopter-mounted spectroradiometer and PRI was calculated from these data. Eddy covariance towers were operating at the four stands and offered a means to calculate LUE. A significant linear relationship was apparent between PRI, calculated from the helicopter spectral data, and LUE, calculated from the eddy covariance data, for the four sites sampled. Reflectance measurements were also made of a Scots pine stand from the eddy covariance tower. Needles were also sampled during the time of spectral data acquisition for xanthophyll pigment determination. Strong linear relationships were observed among PRI, the epoxidation state of the xanthophyll cycle (EPS) and LUE over the green-up period and the diurnal cycle at the canopy scale.

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.

Аннотация: Envisat-MERIS and SPOT Vegetation satelitte data were tested for estimation of vegetation cover disturbance caused by fire and industrial pollution in central and northern Siberia test sites, respectively. MERIS data were used to assess forest disturbance levels on burned sites in Angara region. Chlorophyll indexes (REP and MTCI) were found to allow identifying up to five forest disturbance levels due to high space-borne sensor resolution and sensitivity to chlorophyll content of vegetation. The current vegetation condition was assessed using MTCI index in the northern (Norilsk) test region. The lowest index values calculated for the most severely disturbed vegetation near Norilsk were found to correlate with sulphur concentrations in larch and spruce needles. Another approach to estimating spatial and temporal trends of vegetation condition used the 1998-2005 SPOT-Vegetation satellite data. The relationships obtained between MTCI, NDVI values, and forest mortality were based upon to map the 1998-2005 forest degradation zone dynamics in the northern test site.

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 activities of lipase, peroxidase, IAA-oxidase, superoxide dismutase, and catalase have been comparatively studied in the needles, inner bark of stem and roots of 10-year-old self-sawn Pinus sylvestris trees in Central Siberia under natural conditions and in experiment imitating the effect of permafrost. It is shown that a decrease in the rhizosphere temperature for self-sawn Pinus sylvestris causes not only a change in the morphogenesis of the sprouts of the current year and reduction of the annual ring but also a shift of the natural dynamics of antioxidant enzyme activity to a later time. Before soil thawing, the activity of antioxidant enzymes on the experimental plot weakened thus implying the enhancement of the oxidative stress, while the growth of buds and sprouts is hindered during this period because of the high activity of IAA-oxidase. An active part in the elimination of the oxidative stress consequences belongs to the conjugated pair of antioxidant enzymes superoxide dismutase-catalase.

Аннотация: A comparison of two Siberian moth populations from the Altai Republic (feeding on Siberian fir) and the Tyva Republic (feeding on Siberian larch) has revealed no differences between them with respect to ecophysiological parameters of larval growth and feeding on needles of the same conifer species under laboratory conditions. The index of appropriateness of food plants for the larvae from both populations decreases in the series larch > fir > spruce > pine. The age-related dynamics of parameters characterizing the feeding and growth of larvae are independent of the population to which the insects belong.

Аннотация: Food energy expenditures by gypsy moth at different developmental stages under conditions of feeding on larch needles are described. The distribution of total food energy (%) for metabolism, the formation of exuvia (throughout ontogeny), and the formation of an adult insect is assessed. The proportion of food energy lost with excrements over the entire period of feeding is the same (58%) in females and males. The assimilated part of food energy is distributed differently: energy expenditures for the formation of exuvia and adult insects are greater in females than in males. The proportion of food energy expended for metabolism throughout the insect life span is approximately 30% in both females and males.

Аннотация: Most of the research about the effects of the release of carbon and other chemicals to the atmosphere during forest fir es focuses on emissions from crown fires or slash fires in which a high percentage of the fine fuels are burned However, in many temper-ate and boreal conifer ecosystems, surface fires of varying intensities and severities are an important part of the fire regime. In Russia a large percentage of the area burned in a typical year is in surface fires, which will result in lower carbon emissions than crown fires because of lower fuel consumption. lit Russian boreal for est, different distribution patterns of fire severity across the landscape could produce fourfold differences in carbon release. Furthermore, tree mortality after surface fires is often quite extensive, leading to a pulse in carbon release as needles and other fine fuels fall to the ground and decompose. With extensive tree mortality a decrease in carbon sequestration is expected for several years, until stand level photosynthesis returns to prefire levels. Perhaps the largest potential source of error in estimates of carbon release from biomass fires in Russia is inaccuracy in estimates of burned area. Many published estimates of annual burned area in Russia may be extremely low. On the basis of information on fire return intervals and area of boreal forest, 12 million ha per year may be a reasonable conservative estimate of burned area until better data are available. Based on this estimate, direct and indirect fire-generated carbon emissions from boreal forests worldwide may exceed 20% of the estimated global emissions from biomass burning, making them an important component in understanding global atmospheric chemistry. In considering effects of fire an global atmospheric chemistry, it is important to include the effects of fire severity, postfire mortality, decomposition of fine fuels, and changing postfire vegetation structure as components of fire-induced changes in ecosystem-level carbon flux. But the most important factor may be accurate information on the annual area burned. Levels of carbon storage are likely to be highly sensitive to changes in fire return intervals that result from direct human activities and from climatic changes, making accurate assessments of burned areas and fire severity critical. Strong fire management programs will be key to managing future fire regimes and carbon cycling in Russia's boreal forest. Published by Elsevier Science Ltd.

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: We measured the seasonal dynamics of major and trace elements concentrations in foliage of larch, main conifer species of Siberia, and we analyzed cryogenic soils collected in typical permafrost-dominated habitats in the Central Siberia. This region offers a unique opportunity to study element fractionation between the soil and the plant because of (i) the homogeneous geological substratum, (ii) the monospecific stands (Larix gmelinii) and (iii) the contrasted habitats (North-facing slope, South-facing slope, and Sphagnum peatbog) in terms of soil temperature, moisture, thickness of the active layer, tree biomass and rooting depth. The variation of these parameters from one habitat to the other allowed us to test the effects of these parameters on the element concentration in larch foliage considered with high seasonal resolution. Statistical treatment of data on larch needles collected 4 times in 3 locations during entire growing season (June-September) demonstrated that : (1) there is a high similarity of foliar chemical composition of larch trees in various habitats suggesting intrinsically similar requirements of larch tree growth for nutrients, (2) the variation of elemental concentrations in larch needles is controlled by the period (within the growing season) and not by the geographical location (South-facing slope, North-facing slope or bog zone) and (3) there are three groups of elements according to their patterns of elements concentration in needles over the growing season from June to September can be identified: (1): nutrient elements [P, Cu, Rb, K, B, Na, Zn, Ni and Cd] showing a decrease of concentration from June to September similar to the behaviour of major nutrients such as N, P and K; (2): accumulating elements [Ca, Mg, Mo, Co, Sr, Mn, Pb and Cr] showing an increase of concentration from June-July to September; (3): indifferent elements [Al, Zr, Fe, Ba, Ti, REEs (Pr, Nd, Ce, La, Gd, Er, Dy, Tb, Lu, Yb, Tm, Sm, Ho, Eu), Y, Th and U] showing a decrease of concentration from June to July and then an increase of concentration to September. A number of micronutrients (e.g., Cu, Zn) demonstrate significant resorption at the end of growing season suggesting possible limitation by these elements. Although the intrinsic requirement seems to be similar among habitats, the total amount of element stored within the different habitats is drastically different due to the differences in standing tree biomass. The partitioning coefficients between soil and larch appear to be among the lowest compared to other environments with variable plants, soils and climates. Applying the "space for time" substitution scenario, it follows that under ongoing climate warming there will be an increase of the element stock following enhanced above-ground biomass accumulation, even considering zero modification of element ratios and their relative mobility. In this sense, the habitats like south-facing slopes can serve as resultant of climate warming effect on element cycling in larch ecosystems for the larger territory of Central Siberia.

Аннотация: Quinate:NAP(P)(+)-oxidoreductase (QORase, EC 1.1.1.24), which catalyzes the interconversion of quinic and 3-dehydroquinic acids, was purified from the needles and developing xylem cells of Larix sibirica. The enzymes from these two tissues were partially characterized and compared. QORase from needles had optimum pH at 9.0 and apparent K-m values of 1.84 mM for quinic acid and 0.19 mM for NADP(+). The enzyme was activated by phosphoenolpyruvate. Gallic and protocatechuic acids were formed in a reaction mixture of purified enzyme from needles as final products of quinic acid transformation. QORase from developing xylem cells showed pH optimum at 10.0 and had apparent K-m values of 0.70 mM for quinic acid and 0.05 mM for NADP(+). The enzyme was not affected by PEP. The divalent cations Co2+ and Mn2+ at least doubled activity of QORase from both sources but Mg2+ affected the enzyme from needles only. The spatial organization and regulation of quinic acid metabolism in the autotrophic and heterotrophic cells of conifers and the role of QORase in this process are discussed.

Аннотация: The evaluation of biospheric role of the boreal forests in the accumulation of carbon is connected with the evaluation of organic matter (OM) pool in soils. 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: The decline of pretundra forests at the north of Krasnoyarsk krai induced by emissions from Noril'sk Metallurgical Complex (containing SO2, NOx, and heavy metals) was investigated. Permanent test plots were situated according to a pollution gradient. The vital status of the forests was estimated and the amount of pollutants in leaves or needles, forest litter, and soil was determined. Sulfur content was found to vary from 30 to 500 kg/ha in the upper 0-2 cm layer and from 250 to 1300 kg/ha in the 0-20 cm layer. At distances of up to 40 km from the pollution source, the concentrations of heavy metals (Cu, Ni, and Co) in the upper 0-10 cm soil layer exceeded the background level by a factor of 10-1000. The sensitivity of tree species to pollutants decreases along the range larch-spruce-birchwillow. The zone of damaged forests spreads up to 200 km from emission sources along prevailing wind directions. At a distance of up to 80-100 km, the forests are dead.
