Аннотация: Long-term eddy covariance measurements of energy and water fluxes and associated climatic parameters were carried out above a Scots pine (Pinus sylvestris) forest in the middle taiga zone of Central Siberia. Data from June 1998 through October 2000 are presented. With the exception of winter 1998/1999, data collection over this period were more or less continuous. A distinct seasonality in surface energy exchange characteristics was observed in all years. In early spring in the absence of physiological activity by the vegetation, about 80% of the net radiation was partitioned for sensible heat, resulting in Bowen ratios, beta, as high as 8. In the 1-2 wk period associated with onset of photosynthesis in spring, evaporation rates increased rapidly and beta rapidly dropped. However, even during summer months, sensible heat fluxes typically exceeded latent heat fluxes and beta remained above 2.0. Observed daily evaporation rates varied between 0.5-1.0 mm d(-1) in spring and autumn and 1.5-2 mm d(-1) in midsummer. The overall average for the three growing seasons examined was 1.25 mm d(-1). Precipitation was on average 230 mm for the growing period, with evaporation over the same time being about 190 mm for both 1999 and 2000. This represented only about 35% of the equilibrium evaporation rate. There was typically a positive hydrological balance of 40 mm for the growing season as a whole. However, in all three years examined, evaporation exceeded precipitation totals by 20-40 mm in at least one calendar month during summer. During the growing season, daily averaged surface conductances varied between 0.15 and 0.20 mol m(-2) s(-1) (3-4.5 mm s(-1)) in dry or cool months and 0.30-0.35 mol m(-2) s(-1) (6.5-8 mm s(-1)) in moist and warm months. Despite a negative hydrological balance during midsummer, there was little evidence for reduced canopy conductances in response to soil water deficits. This may have been the consequence of roots accessing water from within or just above a perched water table, located at about 2 m depth.

Аннотация: Rates of CO2 efflux from the floor of a central Siberian Scots pine (Pinus sylvestris) forest were measured using a dynamic closed chamber system and by a eddy covariance system placed 2.5 m above the forest floor. Measurements were undertaken for a full growing season: from early May to early October 1999. Spatial variability as determined by the chamber measurements showed the rate of CO2 efflux to depend on location, with rates from relatively open areas ("glades") only being about 50% those observed below or around trees. This was despite generally higher temperatures in the glade during the day. A strong relationship between CO2 efflux rate and root density was observed in early spring, suggesting that lower rates in open areas may have been attributable to fewer roots there. Continuous measurements with the eddy covariance system provided good temporal coverage. This method, however, provided estimates of ground CO2 efflux rate rates that were about 50% lower than chamber measurements that were undertaken in areas considered to be representative of the forest as a whole. An examination of the seasonal pattern of soil CO2 efflux rates suggests that much of the variability in CO2 efflux rate could be accounted for by variations in soil temperature. Nevertheless, there were also some indications that the soil water deficits served to reduce soil CO2 efflux rates during mid-summer. Overall the sensitivity of CO2 efflux rate to temperature seems to be greater for this boreal ecosystem than has been the case for most other studies.

Аннотация: Using a ground-based and an above-canopy eddy covariance system in addition to stem respiration measurements, the annual respiratory fluxes attributable to soil, stems and foliage were determined for a Scots pine (Pinus sylvestris L.) forest growing in central Siberia. Night-time foliar respiration was estimated on the basis of the difference between fluxes measured below and above the canopy and the stem respiration measurements. Comparison of the effects of night-time turbulence on measured CO2 fluxes showed flux loss above the canopy at low wind speeds, but no such effect was observed for the ground-based eddy system. This suggests that problems with flow homogeneity or flux divergence (both of which would be expected to be greater above the canopy than below) were responsible for above-canopy losses under these conditions. After correcting for this, a strong seasonality in foliar respiration was observed. This was not solely attributable to temperature variations, with intrinsic foliar respiratory capacities being much greater in spring and autumn. The opposite pattern was observed for stem respiration, with the intrinsic respiratory capacity being lower from autumn through early spring. Maximum respiratory activity was observed in early summer. This was not simply associated with a response to higher temperatures but seemed closely linked with cambial activity and the development of new xylem elements. Soil respiration rates exhibited an apparent high sensitivity to temperature, with seasonal data implying a Q(10) of about 7. We interpret this as reflecting covarying changes in soil microbial activity and soil temperatures throughout the snow-free season. Averaged over the two study years (1999 and 2000), the annual respiratory flux was estimated at 38.3 mol C m(-2) a(-1). Of this 0.61 was attributable to soil respiration, with stem respiration accounting for 0.21 and foliar respiration 0.18.

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: Seeds of Scots pine provenances originating from all over Russia were planted in the Boguchany provenance trial at a central Siberian location (southern taiga) in 1974. Eight tree-ring density and width parameters for 16 different provenances were measured with densitometric techniques. The tree-ring data were recorded from 1982 to 1996. Correlation analysis calculated by raw series showed that tree-ring width decreases and percentage of latewood increases with an increase in the latitude of the seed source. High variability was found for raw tree-ring characteristics from tree to tree within each provenance for an observed period (individual variability). The age trend of each tree is well described by the chosen fitting curve, and is similar for the mean series of each provenance. As a consequence of these findings, the indexed chronology for each provenance mainly shows climatic signals. The SD of the indexed chronology (chronological variability) is low for each provenance, showing low sensitivity to climatic influences. A cluster analysis of provenances represented by tree-ring characteristics differentiated the provenances into three groups. However, the statistical distance between the groups was minor. So we can confirm that Scots pine provenances are highly adaptable to local ecological conditions and regional climatic influences.

Аннотация: Siberian boreal forest fires burn large areas annually, resulting in smoke that release large amounts of particulate emission into the atmospere. We sampled aerosol emissions from experimental fires of three Scots pine (Pinus sylvestris L.) forest sites of central Siberia. Emissions from ground-based aerosol samples were 0.1-0.7 t/ha. This value represented 1%- 7% of the total biomass (10-30 t/ha) consumed during the experimental fires. We were able classify the chemical composition of 77%-90% of the mass of particulate the emissions. Chemical analysis indicated that an average of 8%-17% of the particulate composition was of mineral emission.

Аннотация: We evaluated the influence of stand density on the growth and development of monoculture plantations of Scots pine, larch and Norway spruce. The planting density ranged from 500 to 128,000 trees/ha. After 22 years, tree height was not affected by density, though the height of pine and larch (8m) was greater than spruce (6m). Diameter declined exponentially with increasing density, but the slope was too low to offset the contribution of more trees to the stand total basal area and stem volume. Basal area and stem volume per hectare were greatest at the most extreme density for all three species, refuting ideas of "stagnation" at high density.

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: 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.

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.

Аннотация: Research to monitor and document surface fire behavior characteristics in Scots pine forests of Central Siberia. Fifteen successful burns were conducted under a range of burning conditions (2000-2003). Fuel consumption, depth of burn, rate of spread, and fire line intensity were successfully modelled using the Russian Moisture Index (PV-1) or the Canadian Forest Fire Weather Index System as the independent variables, which should prove useful in suppression efforts undertaken by Russian fire agencies.
