Аннотация: The use of fire as a key ecosystem driver in many disturbance shaped landscapes of Eurasian has modified ecosystems into significant cultural landscapes. In these ecosystems, people over time have played a significant role in creating, maintaining, expanding or changing the landscape components that now have high conservation value.

Аннотация: Analyses demonstrate the far-reaching effects of a changing climate on vegetation cover. Hot spots of potential Siberian vegetation change are predicted for 1990. Observations of vegetation change in Siberia have already been documented in the literature. Vegetation habitats should be significantly perturbed by 2020, and markedly perturbed by 2080. Because of a dryer climate, forest-steppe and steppe-ecosystems, rather than forests, are predicted to dominate central Siberian landscapes. Despite the predicted increase in warming, permafrost is not predicted to thaw deep enough to support dark taiga over the Siberian plain, where the larch taiga will cntinue to be the dominant zonobiome. On the contrary, in the southern mountains in the absence of permafrost, dark taiga is predicted to remain the dominant orobiome.

Аннотация: Climatic and geographic patterns of the spatial precipitation distribution in Central Siberia are studied on a regional level. Computer models of spatiall precipitation distribution were developed for the Yenisei Mountain Chain, Eastern Sayan, and the South-eastern Trans-Baikal region. Owing to irregular spatial distribution of precipitaion three groups of landscapes were defined: (1) slopes of west, north-west aspect with orographic precipitation; (2) shadow slopes in mountain regions; (3) plain landscapes. Obtained equautions show correlations between the amount of precipitation and altitude, geographical latitude, distance from barrier ridge and other parameters.

Аннотация: An analysis of information on the groundwater dynamics, frequency of fire events, and postfire progressive-age stages of vegetation in the swamp-forest ecosystems of the southern taiga and forest-steppe zone of the West Siberian Plain has shown that fire events are a permanent factor that controls the scales and dynamics of the forest and swamp formation processes under these specific conditions in the modern era. The greatest influence on the dynamics of ecosystems is exerted by the frequency of fires. The scope and depth of the transformation of swamp ecosystems affected by the pyrogenic factor are due to their environmental regimes and have their own properties in different landscapes.

Аннотация: The soil formation was studied in the 21- to 35-year-old pine plantations created on the overburden dumps of the Nazarovskaya Depression without applying the material of the humus horizon. The surface technogenic formations under the pine plantations belong to the group of naturfabricats (surface formations devoid of the humus horizon and composed of natural substrate). The morphological characteristics, bulk chemical and particle-size compositions, and labile properties of the soils indicate that the accumulation and transformation of organic matter are dominant processes in the artificially planted forests. The accumulation of organic residues and destruction and humification are tightly related to the environmental conditions transformed by the technogenesis and conceal other processes forming the soil profiles. Quasizems created for agricultural production purposes were the objects of the study. They were formed by covering the technically planned overburden rocks with the material of humus layers. The thickness of the humus horizons of the quasizems varies greatly (25-64%); the variation of the humus reserves in them is 34-122%. Middle-profile horizons have not been formed by the present time.

Аннотация: Regional Siberian studies have already registered climate warming over the last several decades. We evaluated ongoing climate change in central Siberia between 1991 and 2010 and a baseline period, 1961-1990, and between 1991 and 2010 and Hadley 2020 climate change projections, represented by the moderate B1 and severe A2 scenarios. Our analysis showed that winters are already 2-3A degrees C warmer in the north and 1-2A degrees C warmer in the south by 2010. Summer temperatures increased by 1A degrees C in the north and by 1-2A degrees C in the south. Change in precipitation is more complicated, increasing on average 10% in middle latitudes and decreasing 10-20% in the south, promoting local drying in already dry landscapes. Hot spots of possible forest shifts are modeled using our Siberian bioclimatic vegetation model and mountain vegetation model with respect to climate anomalies observed pre-2010 and predicted 2020 Hadley scenarios. Forests are predicted to shift northwards along the central Siberian Plateau and upslope in both the northern and southern mountains. South of the central Siberian Plateau, steppe advancement is predicted that was previously non-existent north of 56A degrees N latitude. South of 56A degrees N, steppe expansion is predicted in the dry environments of Khakasiya and Tyva. In the southern mountains, it is predicted that the lower tree line will migrate upslope due to increased dryness in the intermontane Tyvan basins. The hot spots of vegetation change that are predicted by our models are confirmed by regional literature data.

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: Specific features of the soil formation and soil cover patterns in the mountainous alpine tundra and forest landscapes of the Central Khangai Range are analyzed. It is shown that the specific mucky grayhumus permafrost-affected soils are only formed under larch forests within the tundra-alpine and forest zones. Other soils have a wider geographic area. The morphological, physicochemical, and chemical characteristics of the widespread soils are given. A medium-scale map of the soil cover patterns-soil complexes, combinations, and mosaics-has been developed for the studied area.

Аннотация: The vastness or scale of the Siberian forest presents both an opportunity and a challenge. It is a major source of softwood fiber in a world in which softwood fiber is in great demand. Its vastness and isolation from markets make it more difficult to regulate harvesting and to get both raw material and processed wood to consumers. Both natural and anthropogenic disturbances (e.g., fire, climate change) greatly alter forest landscapes and complicate the management of the resource for sustainability. We characterize the current condition of the Siberian forest in Russia and recommend future directions for this globally-important resource. The future is promising because Siberia has a relatively well-developed forest infrastructure, along with highly-trained scientists, an existing structure of forest enterprises, and some protective and regulatory measures that serve as a basis for developing and sustaining the resource. However, investments directed at modernization, especially technological, are needed to enhance the country's capacity to promote sustainable development in the forestry sector.

Аннотация: Terrestrial and aquatic dissolved organic matter (DOM) was characterized to trace the likely processes of DOM formation and stream export in a permafrost-dominated watershed in central Siberia. Stream samples were collected in spring (May-June 2003) and summer (July-August 2003) at both low flow and stormflow. Dissolved organic matter was analyzed by pyrolysis/gas chromatography/mass spectrometry, and identified pyrolysis products were simultaneously analyzed for compound-specific isotope ratios by isotope ratio mass spectrometry. Pyrograms of terrestrial and stream DOM contained a similar series of pyrolysis products, suggesting a terrestrial origin for DOM in the small stream draining our study catchment. However, despite the overall similarity of chemical composition of stream DOM at different seasons, we also observed distinct differences in isotopic fingerprint between seasons and hydrologic phases ( stormflow versus low flow). This variation appears to be due to the changing origin of stream DOM from different soil layers and the catchment sources following permafrost thawing during the frost-free period. In general, chemical and isotopic composition of stream DOM was similar to DOM produced in soils of colder north facing slopes ( P 0.01) with a shallow active layer. South facing slopes with deeper active layers produce little DOM that enters the stream, suggesting that DOM produced in the active layer is retained and stabilized in underlying, unfrozen mineral soils. Climate change that results in additional seasonal thawing of permafrost-dominated landscapes will decrease the amount of DOM exported to riverine systems and change its chemical composition.

Аннотация: The Sayano-Shushensky Nature Reserve is a standard primeval locus of high conservation value which remained undisturbed landscapes within the Altai-Sayan Mountain Land. In the plant cover the altitudinal belts are clearly expressed. The northern part of the Sayan-Shushensky reserve is included in moist areas of the Altai-Sayan forest vegetation zone and the Southern part of it is included in insufficiently moist areas of Central Asian forest zone. The ground vegetation of the reserve is presented by high-mountain tundra, meadows and shrub thicket sites, high-mountain open Pinus sibirica D u. T o u r. and Larix sibirica L e d e b. woodland, dark and light coniferous taiga, coniferous subtaiga, forest-steppe and steppe. As a whole forests occupy somewhat about 60% of the territory. Ecocenotic groups of species found in individual phytocoenoses in river basins of the northern part of the nature reserve are qualitatively different in composition and share from those ones found in the southern river basins. In the north, the high mountain ecocenotic species group enjoys the greatest abundance, and forest-meadow, taiga, and bog species are also represented substantially. Steppe and forest-steppe species are absent. Alpine, steppe, and forest-steppe species are found in equal shares in the southern part of the forest reserve. Invasive species are quite many. Taiga species contribution is three times less than in the north of the reserve. Conditions climatically optimal for the greatest species diversity are the result of a perfect balance of heat and moisture characteristics of subtaiga/forest-steppe altitudinal belt complexes (ABC). However, changes in phytochorological- and alpha-diversity of individual phyl.ocoenoses are influenced by ecological and phytocoenotic factors combined. The biggest number of species in the reserve occurs along the forest distribution boundaries - in subtaiga and high mountain open woodland whereas species are the fewest in mountain taiga. Conversely, phytomass loading is the greatest in mountain taiga and it decreases gradually towards alpine tundra and steppes.

Аннотация: In this study, we have analyzed the degradation of pretundra forests and distinguished the levels of pollution using ground-based and remote-sensing data. The study region is located in the area exposed to emissions from the Norilsk Mining and Smelting Works. The main components of emissions are sulfur dioxide, nitrogen oxide, and heavy metals. Currently, the zone of damaged forests extends for more than 200 km. The comparison of the zones of degradation of pretundra vegetation distinguished in satellite images with the results of ground-based observations yielded high similarity coefficients (0.73-0.83) of the Kappa statistics. The zones of vegetation state were classified by NDVI values. The images from the NOAA/AVHRR satellite may be used for delimiting the zones of vegetation degradation by the proposed method.

Аннотация: In this paper NOAA AVHRR data acquired at the Sukachev Institute of Forest in Siberia, Russia is evaluated for forest management mapping applications. First a classification of the entire 1000 km x 3000 km transect was performed, but was found to be too general to be of value. More useful interpretation procedures require a landscape-ecological approach. This means that computer classification should be made separately for segments of territory based ecologically distinct regions. This segmentation of the transect into ecological regions was found to improve the level of detail available in the classification. Using this approach AVHRR data were found to be adequate for small scale mapping at the level of vegetation types or plant formations. A limited study using AVHRR data for classification of mountainous regions showed that AVHRR-derived maps were more detailed than existing landscape maps. AVHRR derived classifications also compared favourably to larger scale forest management maps of softwood and hardwood forests. Current forest management in Siberia relies on very small-scale inventory maps. Thus, there is a potential role for AVHRR (or Terra) data for northern Siberian forest monitoring. The southern forests of the Yenisey meridian (below the 57th parallel) are less uniform due to considerable human activity, and NOAA/AVHRR data will play a subordinate role in its monitoring.

Аннотация: Data on the bulk content of microelements in thixotropic and homogeneous cryozems of autonomous (eluvial and transeluvial) landscapes in the northern taiga and forest-tundra subzones in the Yenisei River basin are presented. The main associations of elements and their correlative relationships with soil properties were determined for genetic horizons. Weak differentiation of most microelements in the soil profile is typical for these soils, which can be attributed to severe hydrothermic conditions of the region and to the regional peculiarities of chemical composition of parent rocks.

Аннотация: A range of observations points towards earlier onset of spring in northern high latitudes. However, despite the profound effects this may have on vegetation-atmosphere exchange of carbon (NEE), vegetation-atmosphere physical coupling, or the location of the tundra-taiga interface, the number of studies that investigate winter-spring transition fluxes in contrasting northern vegetation types is limited. Here, we examine spring ecosystem-atmosphere energy and carbon exchange in a Siberian pine forest and mire. Divergent surface albedo before and during snow-melt resulted in daytime net radiation (R-n) above the forest exceeding R. above the mire by up to 10 MJ m(-2). Until stomata could open, absorbed radiation by the green pine canopy caused substantial daytime sensible heat fluxes (H 10 MJ m(-2)). H above the mire was very low, even negative (-2 MJ M-2), during that same period. Physiological activity in both ecosystems responded rapidly to warming temperatures and snow-melt, which is essential for survival in Siberia with its very short summers. On days with above-zero temperatures, before melt. was complete, low rates of forest photosynthesis (1-2 mu mol m(-2) s(-1)) were discernible. Forest and mire NEE became negative the same day, or shortly after, photosynthesis commenced. The mire lagged by about two weeks behind the forest and regained its full carbon uptake capacity at a slower rate. Our data provide empirical evidence for the importance the timing of spring and the relative proportion of forest vs. mire has for late winter/spring boundary-layer growth, and production and surface-atmosphere mixing of trace gases. Models that seek to investigate effects of increasingly earlier spring in high latitudes must correctly account for contrasting physical and biogeochemical ecosystem-atmosphere exchange in heterogeneous landscapes.

Аннотация: The spatial pattern of Siberian silkmoth outbreak in south Siberian mountains was analysed based on SPOT VEGETATION data. A digital elevation model (DEM) was also used to relate outbreak area dynamics with topographic elements (elevation, azimuth and slope steepness). To avoid bias of spatial pattern data, areas with a given damage category and with given azimuth, slope steepness and elevation were referenced to the areas with similar parameters within the entire study area. The outbreak began between the elevations of similar to 430-480 m and on south-west slopes with steepness 5 degrees; these conditions appear to be the most favourable pest habitat. As the pest searched for food it moved up and down slope, resulting in an elevation distribution split within a range of similar to 390-540 m and slope steepness up to 15 degrees. In the final phase the azimuth distribution of damaged stands became even, showing that pests at this phase settle in non-optimal habitat. The final outbreak area was similar to 20 000 ha, which is in good agreement with on-ground data. The correlation between the initial phase of infestation and topographic features can be used to prioritize pest monitoring. Data obtained show that the SPOT VEGETATION sensor is applicable for monitoring taiga landscapes vulnerable to Siberian silkmoth outbreaks.

Аннотация: The latest catastrophic Siberian silkmoth (Dendrolimus superans sibiricus Tschetw.) outbreak occurred in central Siberia during 1994-1996. The relationship between forest stand mortality from insects and topographic features (azimuth, elevation, slope steepness) was analyzed based on a high-resolution digital elevation model, a pest damage map and Terra/MODIS data. It was found that pest-induced forest mortality patterns depend on topographic features. Before the outbreak the major part of host forest species was found within the elevation zone of 150-500 m. After the outbreak, surviving dark-needle stands were found mainly at elevations higher than 400 m. The greatest damage was observed at elevations between 210 and 320 m, whereas maximum mortality was observed at elevations of about 200 m and minimal mortality at elevations of 300 m. With respect to slope steepness, maximum damage for all categories was observed for slopes of 5-20В°. Slightly damaged stands were most common at low slope angle (about 5В° or less), whereas the highest proportion of stands with high tree mortality was found on steeper slopes. With respect to azimuth, insect damage is mostly uniform, with a small increase in damage on the south-west-facing slopes. The spatial pattern of the silkmoth outbreak can provide a basis for prioritizing Siberian silkmoth outbreak monitoring. В© 2007 Taylor & Francis.

Аннотация: A Russian-American research team investigates the impacts of long-term intensive working of gold deposits on landscapes in the Middle Siberian taiga. These impacts include the displacement of bedrock and alluvial deposits, deforestation, and increasing fire incidence. Landsat 7 satellite imagery and field data were used in assessing the information yield of satellite scanner channels in the process of classification of the registered images. A schematic electronic map was constructed that shows zones of gold mining, predominant vegetation species, cutover and burned areas, and natural and artificial water bodies.
