Аннотация: Surface soils (organic layer and 0-10 cm mineral soil) from larch forests, Central Siberia, had small pool size of soil inorganic N, while higher values can be observed especially in organic layer in N fertilized sites. Annual leachate of inorganic N was also small before N fertilization, while greater values were observed beneath organic layer in high N site after fertilization. Thus, N treatment seems to stimulate inorganic N dynamics of soil surface, and it may consequently lead to stimulation of lower soils. Dissolved organic nitrogen (DON) was the most important N form constantly supplying dissolved N to soil circumstances in this site, suggesting a possibility of organic N to control on ecosystem processes in these forests.

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: The influence of ground fires varying intensity on ground vegetation has been studied in pine forests of middle taiga in Central Siberia. These fires lead to reduction of a percent cover and biomass of the ground vegetation regardless of their intensity. Mosses and lichens are killed. Post-fire recovery of the ground vegetatiion is determined by the fire intensity, litter burning depth and initial forest type.

Аннотация: Warming induced (1) tree upward and northward migration and (2) krummholz transformation in alpine and northern ecotones, (3) a "dark needle conifers (DNC)" migration within "mixed taiga - zone of larch dominance" ecotone, (4) growth increment increase and stand denisification, (4) DNC proportion increase, which should lead an albedo decrease, amplifying warming at local scale. Observed radial and apical growth increment increases were correlated with both, air temperatures and atmospheric CO2 concentration increases.

Аннотация: Problem of wildfires has not been resolved anywhere in the world. Mere increase of technical power does not lead to desirable results. Forests of developed countries burn as actively as those in Africa or in Russia. The main reasons of wildfire problem are as follows: (1) Constant wandering of dry seasons over the planet causing outbreaks of wildfires. (2) Unpredicted self-development of ordinary wildfires into awful fire disasters. (3) Difficulties in delivery and use of heavy machines on hardly accessible territories. (4) Absence of a perfect technique for economic evaluation of how effectively the wildfire control system works. (5) Absence of the system of payments encouraging wildfire fighters. To solve the problem of wildfires in Russia it is necessary to: (1) Create the Russian wildfire behaviour and fire effects prediction system on the basis of the developed classification of vegetation fuels and methods of their mapping as well as maximum utilization of forest inventory information and Geographic Information System (GIS). (2) Elaborate a technique of proper wildfire monitoring including estimation of vegetation damage. (3) Improve daily rating of regional fire danger. (4) Improve fire-preventive arrangement of the territory covered by vegetation, the main goal being creation of favourable conditions for active fire management. (5) Choose the main direction in elaboration of fire-fighting means and methods taking into account their universality, simplicity, reliability, etc. (6) Elaborate an improved technique for estimation of economic effectiveness of the wildfire control system. (7) Develop international cooperation of scientists and professionals in fire management.

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 structure and functions of the microbial complexes in the soils after surface fires of different intensity were studied. The fires of high and medium intensity were found to lead to a significant decrease in the number and functional activity of microorganisms participating in the nitrogen-carbon cycle. The degree of changes in the postfire status of the soil microbocenoses was revealed to be related to the joint action of pyrogenesis and the hydrothermal conditions at the moment of the fire rather than to the fire intensity. The favorable combination of the elevated soil moisture and soil heating stimulates the microbiological processes of organic matter mineralization, thus, improving the forest-growing conditions for the pine forests. The microbial biomass, basal respiration, and the microbial metabolic coefficient are shown to adequately reflect the postfire status of the microbial complexes.

Аннотация: Adequate quantification of evapotranspiration (ET) is crucial to assess how climate change and land cover change (LCC) interact with the hydrological cycle of terrestrial ecosystems. The Mongolian Plateau plays a unique role in the global climate system due to its ecological vulnerability, high sensitivity to climate change and disturbances, and limited water resources. Here, we used a version of the Terrestrial Ecosystem Model that has been modified to use Penman-Monteith (PM) based algorithms to calculate ET. Comparison of site-level ET estimates from the modified model with ET measured at eddy covariance (EC) sites showed better agreement than ET estimates from the MODIS ET product, which overestimates ET during the winter months. The modified model was then used to simulate ET during the 21st century under six climate change scenarios by excluding/including climate-induced LCC. We found that regional annual ET varies from 188 to 286 mm yr(-1) across all scenarios, and that it increases between 0.11 mm yr(-2) and 0.55 mm yr(-2) during the 21st century. A spatial gradient of ET that increases from the southwest to the northeast is consistent in all scenarios. Regional ET in grasslands, boreal forests and semi-desert/deserts ranges from 242 to 374 mm yr(-1), 213 to 278 mm yr(-1) and 100 to 199 mm yr(-1), respectively; and the degree of the ET increase follows the order of grassland, semi-desert/desert, and boreal forest. Across the plateau, climate-induced LCC does not lead to a substantial change (<5%) in ET relative to a static land cover, suggesting that climate change is more important than LCC in determining regional ET. Furthermore, the differences between precipitation and ET suggest that the available water for human use (water availability) on the plateau will not change significantly during the 21st century. However, more water is available and less area is threatened by water shortage in the Business-As-Usual emission scenarios relative to level-one stabilization emission scenarios.

Аннотация: Northern Eurasia, the largest land-mass in the northern extratropics, accounts for similar to 20% of the global land area. However, little is known about how the biogeochemical cycles, energy and water cycles, and human activities specific to this carbon-rich, cold region interact with global climate. A major concern is that changes in the distribution of land-based life, as well as its interactions with the environment, may lead to a self-reinforcing cycle of accelerated regional and global warming. With this as its motivation, the Northern Eurasian Earth Science Partnership Initiative (NEESPI) was formed in 2004 to better understand and quantify feedbacks between northern Eurasian and global climates. The first group of NEESPI projects has mostly focused on assembling regional databases, organizing improved environmental monitoring of the region, and studying individual environmental processes. That was a starting point to addressing emerging challenges in the region related to rapidly and simultaneously changing climate, environmental, and societal systems. More recently, the NEESPI research focus has been moving toward integrative studies, including the development of modeling capabilities to project the future state of climate, environment, and societies in the NEESPI domain. This effort will require a high level of integration of observation programs, process studies, and modeling across disciplines.

Аннотация: Data from the " Biome" information system were used to construct an ordination of zonal categories of vegetation cover in southern Siberia along the axes of heat supply and continentality. The changes of climate that occurred from the end of the 1960. s to 2007 are estimated. It is shown that they can lead to transformation of the composition of potential forest vegetation in a number of regions. We discuss the forecasted and observed variants of long-term successions in different sectoral-zonal classes of subtaiga and forest-steppe, including the risk of a reduction in the areas of separate forest-forming species.

Аннотация: The post-fire succession over the past 350 years have been analyzed so as to predict the effect of the increase in fires that is being anticipated to go hand in hand with climate change in southern Siberia, Russian Federation. Succession is defined to be the gradual supplanting of one plant community by another as conditions change either by natural means or an alter disturbance. A number of stages are being noticed in most successions on which different collections of species dominate. Finally, the last part of it is when the species composition no longer changes with time in the absence of natural or human-caused disturbances. It has been found out that the predicted increase in fires resulting from climate change in southern Siberia will probably reduce the number of larch and shade-tolerant conifers in favor of Scots pine, birch and aspen, as well as with non-tree plant communities of bushes, grasses and herbs. The continues warm and humid climate will lead to some changes in the composition of forest ecosystems that are not in favor economically. Thus, it is now necessary to have management plans for the plantations in Siberian pine to consider the increased risk of destructive surface fires and focus on fire protection.

Аннотация: The effect of climate change on the distribution, intensity, and transforming role of wild fires is considered. A general overview of the current wild fire regimes (WRs) and impacts on forest ecosystems and environment is provided. One distinctive feature of WRs is the increasing frequency of disastrous wild fires. The application of various remote sensing instruments has shown that the average vegetation wild fire area in Russia for 1998-2010 accounted for 8.2 +/- 0.8 x 10(6) ha, with about two-thirds of wildfires occurring on forest lands and half on the forested lands. The average annual fire carbon balance during the above period was 121 +/- 28 Tg C yr(-1), including 92 +/- 18 Tg C yr(-1) emitted from the forested land. The forecasts based on the General Circulation Models suggest the dramatic acceleration of fire regimes by the end of the 21st century. Taking into account the increase in the dryness of the climate and the thawing of permafrost, this will likely lead to a dramatic loss of forested area and the impoverishment of the forest cover over a major part of the forest zone. A transition to adaptive forestry would allow a substantial decrease of the expected losses. This paper takes a brief look at the general principals of adapting forest fire protection system to climate change, which is considered an integral part of the transition to sustainable forest management in Russia.

Аннотация: Ongoing climatic changes potentially affect tree-line ecosystems, but in many regions the observed changes are superimposed by human activities. We assessed how the forest-tundra ecotone has changed during the last century in the Putorana Mountains, northern Siberia, an extremely remote and untouched area in Eurasia. A space-for-time approach was used to determine the spatio-temporal dynamics of forest structure and biomass along an altitudinal transect. From the closed larch forest to the upper tree line, the mean age of Larix gmelinii (Rupr.) decreased considerably from 220 to 50 years ago. At the current upper species line, there is a strong and successful germination of larch, with 1500 saplings per hectare, indicating an ongoing filling-in, a densification of a formerly open forest and an upslope shift of the tree-line position (approximately 30 to 50m in altitude during the last century). The forest expansion coincided with large increases in winter precipitation during the 20th century. In contrast, tree growth rates were significantly positively related to summer temperatures, neither of which increased markedly. The total aboveground biomass decreased from approximately 40tha -1 in the closed larch forest to 5tha -1 at the tree line. Our study demonstrates that ongoing climatic changes lead to an upslope expansion of forests in the remote Putorana Mountains, which alters the stand structure and productivity of the forest-tundra ecotone. These vegetation changes are very probably of minor importance for aboveground carbon sequestration, but soil carbon data are needed to estimate the impact of the forest expansion on the total ecosystem carbon storage.

Аннотация: Climate change will alter ecosystem metabolism and may lead to a redistribution of vegetation and changes in fire regimes in Northern Eurasia over the 21st century. Land management decisions will interact with these climate-driven changes to reshape the region's landscape. Here we present an assessment of the potential consequences of climate change on land use and associated land carbon sink activity for Northern Eurasia in the context of climate-induced vegetation shifts. Under a 'business-as-usual' scenario, climate-induced vegetation shifts allow expansion of areas devoted to food crop production (15%) and pastures (39%) over the 21st century. Under a climate stabilization scenario, climate-induced vegetation shifts permit expansion of areas devoted to cellulosic biofuel production (25%) and pastures (21%), but reduce the expansion of areas devoted to food crop production by 10%. In both climate scenarios, vegetation shifts further reduce the areas devoted to timber production by 6-8% over this same time period. Fire associated with climate-induced vegetation shifts causes the region to become more of a carbon source than if no vegetation shifts occur. Consideration of the interactions between climate-induced vegetation shifts and human activities through a modeling framework has provided clues to how humans may be able to adapt to a changing world and identified the trade-offs, including unintended consequences, associated with proposed climate/energy policies. © 2014 IOP Publishing Ltd.

Аннотация: This paper traces the dynamics of the living ground cover at the initial stage of pyrogenic succession (1-9 years) after different-intensity surface fires in the pine forests of the Lower Angara region. Depending on their intensities, fires have reduced the foliage cover and ground-cover biomass. The greatest changes occur in case of medium-intensity and high-intensity fires that change the horizontal structure of plant microgroups and lead to the death of moss-lichen layers. © 2014 Pleiades Publishing, Ltd.

Аннотация: The monitoring of hilly peatbogs has been found to yield valuable information on technogenic changes in the environment. The intensive accumulation of heavy metals and sulfur has been shown to occur in the top layer of peat deposits (usually no deeper than 5 cm and sometimes as deep as 15 cm). The depth of penetration of anthropogenic contaminant fluxes into the peat deposits do not exceed 30–35 cm. Monitoring of adverse changes evoked by sulfur emissions should be carried out in bog ecosystems of the valley of the Rybnaya River, while the effects of heavy metals should be assessed in areas close to industrial objects of the cities of Norilsk and Talnakh.

Аннотация: Global warming is most pronounced in high-latitude regions by altering habitat conditions and affecting permafrost degradation, which may significantly influence tree productivity and vegetation changes. In this study, by applying a "space-for-time" approach, we selected three plots of Larix gmelinii forest from a continuous permafrost zone in Siberia with different thermo-hydrological soil regimes and ground cover vegetation with the objective of assessing how tree growth and productivity will change under different stages of permafrost degradation. A tree-ring multi-proxy characterization of mature trees was used to identify shift in ecophysiological responses related to the modified plant-soil system. Variability of tree-ring width (1975-2009), stable isotope ratios (oxygen and carbon, 2000-2009) and xylem structural characteristics (2000-2009) under climatic conditions of particular years indicated that an increased depth of the soil active layer will initially lead to increase of tree productivity. However, due to an expected water use increase through transpiration, the system might progressively shift from a temperature to a moisture-limited environment. (C) 2015 Elsevier GmbH.

Аннотация: Estimations of tree annual biomass increments are used by a variety of studies related to forest productivity or carbon fluxes. Biomass increment estimations can be easily obtained from diameter surveys or historical diameter reconstructions based on tree rings' records. However, the biomass models rely on the assumption that wood density is constant. Converting volume increment into biomass also requires assumptions about the wood density. Wood density has been largely reported to vary both in time and between trees. In Norway spruce, wood density is known to increase with decreasing ring width. This could lead to underestimating the biomass or carbon deposition in bad years. The variations between trees of wood density have never been discussed but could also contribute to deviations. A modelling approach could attenuate these effects but will also generate errors. Here a model of wood density variations in Norway spruce, and an allometric model of volume growth were developed. We accounted for variations in wood density both between years and between trees, based on specific measurements. We compared the effects of neglecting each variation source on the estimations of annual biomass increment. We also assessed the errors of the biomass increment predictions at tree level, and of the annual productivity at plot level. Our results showed a partial compensation of the decrease in ring width in bad years by the increase in wood density. The underestimation of the biomass increment in those years reached 15 %. The errors related to the use of an allometric model of volume growth were modest, around ±15 %. The errors related to variations in wood density were much larger, the biggest component being the inter-tree variability. The errors in plot-level annual biomass productivity reached up to 40 %, with a full account of all the error sources. © Author(s) 2015.
