Аннотация: The obtained experimental data testify that even in the case of stands mortality as a result of ground fires it is right to count on quite successful natural regeneration of Gmelin larch on burned areas. It is right to consider genetically conditioned ability of Larix gmelini to conserve a part of quality seeds in ripe cones for 3-4 years as an adaptive reaction of the species to periodical wildfire impacts which are the main destabilizing factor in high latitudes of real zone in Eurasia.

Аннотация: The long-term wildfire dynamics, including fire return interval (FRI), in the zone of larch dominance and the "larch-mixed taiga" ecotone were examined. A wildfire chronology encopassing the fifteenth through the twentieth centuries was developoed by analyzing tree stem fire scars. Average FRI determined from stem fire scar dating was 82 +,- 7 years in the zone of larch dominance. FRI was found to be dependent on site topography. FRI on north-east facing slopes in the zone of larch dominance was 86 +,- 11 years. FRI was siignificantly less on south-west facing slopes at 61 +,- 8 years and flat terrain at 68 +,- 14 years. The implications of the observed trends on the larch community are discussed.

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).

Аннотация: Wildfire is the dominant natural disturbance in boreeal regions, which act as a catalyst for regulating successional processes under the control of weather and climate. Large-scale reanalysis and ground-station interpolated meteorological data are used to estimate local- and regional-scale fire weather for a normal and an extreme fire year. The ability of large-scale weather data to estimate fire weather provides confidence in the relevance of large-scale data to be used to enhance fire weather prediction in remote regions where station data are sparse and also its potential use in estimating large-scale future fire danger.

Аннотация: Boreal forests constitute the world's largest terrestrial carbon pools. The main natural disturbance in these forests is wildfire, which modifies the carbon budget and atmosphere, directly and indirectly. Wildfire emissions in Russia contribute substantially to the global carbon cycle and have potentially important feedbacks to changing climate. Published estimates of carbon emissions from fires in Russian boreal forests vary greatly depending on the methods and data sets used. We examined various fire and vegetation products used to estimate wildfire emissions for Siberia. Large (up to fivefold) differences in annual and monthly area burned estimates for Siberia were found among four satellite-based fire data sets. Official Russian data were typically less than 10% of satellite estimates. Differences in the estimated proportion of annual burned area within each ecosystem were as much as 40% among five land-cover products. As a result, fuel consumption estimates would be expected to vary widely (3%-98%) depending on the specific vegetation mapping product used and as a function of weather conditions. Verification and validation of burned area and land-cover data sets along with the development of fuel maps and combustion models are essential for accurate Siberian wildfire emission estimates, which are central to balancing the carbon budget and assessing feedbacks to climate change.

Аннотация: A fire history of northern larch forests was studied. These larch forests are found near the northern limit of their range at similar to 71 degrees N, where fires are predominantly caused by lightning strikes rather than human activity. Fire-return intervals (FRIs) were calculated based on fire scars and dates of tree natality. Tree natality was used as an approximation of the date of the last fire. The average FRI was found to be 295 +/- 57 years, which is the longest reported for larch-dominated stands. Prior studies reported 80-90-year FRIs at 64 degrees N and similar to 200 years near the latitude of the Arctic Circle. Comparing data from fires that occurred in 1700-1849 (end of the Little Ice Age, LIA) and 1850-1999 (post-LIA warming) indicates approximately twice as many fires occurred during the latter period. This agrees with the hypothesis that observed climatic warming will result in an increase in fire frequency. Our results also indicate that fires that did not leave visible fire scars on the tree stem may be identified based on the date of growth release revealed from dendrochronology.

Аннотация: Regional studies have shown that winters warmed 2-3 degrees C while summers warmed 1-2 degrees C during the1960-2010 period in central Siberia. Increased warming predicted from general circulation models (GCMs) by the end of the century is expected to impact Siberian vegetation. Our goal is to evaluate the consequences of climate warming on vegetation, forests, and forest-forming tree species in central Siberia. We use our envelope-type bioclimatic models of the Siberian forests and major tree conifer species based on three climatic indices which characterise their warmth and moisture requirements and cold resistance, and on one soil factor that charactrises their tolerance to permafrost. Coupling our bioclimatic models with the climatic indices and the permafrost distributions, we predict the potential habitats of forests and forest-forming tree species in current climate conditions and also in the 2080 projected climate. In the 2080 drier climate conditions, Siberian forests are simulated to decrease significantly and shift northwards while forest-steppe and steppe would come to dominate 50 % of central Siberia. Permafrost is not predicted to thaw deep enough to sustain dark (Pinus sibirica, Abies sibirica, and Picea obovata) taiga. Dahurian larch (L. gmelinii+cajanderi), which is able to withstand permafrost, would remain the dominant tree species. Light conifers (Larix spp. and Pinus sylvestris) may gain an advantage over dark conifers in a predicted dry climate due to their resistance to water stress and wildfire. Habitats for new temperate broadleaf forests, non-existent in Siberia at present, are predicted by 2080.

Аннотация: Verified estimates of wildfire area and related carbon emissions in territories of Russia are reported for the period of 1998-2010. It is shown that the average burnt area is estimated to be at 8.23 million hectares per year (uncertainty +/- 9.0%, confidence interval 0.9), and carbon emissions-121 Tg C yr(-1) (+/- 23%), with a significant interannual variability of these indicators. A quantitative characteristic of fire emissions by species is reported. Forests are a source of three quarters of all carbon emissions caused by wildfires. A significant acceleration of fire regimes is expected during the 21st century as a result of climate change in the country.

Аннотация: Frequent measurements of dissolved organic (DOC) and inorganic (DIC) carbon concentrations in rivers during snowmelt, the entire ice-free season, and winter were made in five large watersheds (15 000-174 000 km(2)) of the Central Siberian Plateau (Yenisey River basin). These differ in the degree of continuous permafrost coverage, mean annual air temperature, and the proportion of tundra and forest vegetation. With an annual DOC export from the catchment areas of 2.8-4.7 gC m(-2) as compared to an annual DIC export of 1.0-2.8 gC m(-2), DOC was the dominant component of terrigenous C released to rivers. There was strong temporal variation in the discharge of DOC and DIC. Like for other rivers of the pan-arctic and boreal zones, snowmelt dominated annual fluxes, being 55-71% for water runoff, 64-82% for DOC and 37-41% for DIC. Likewise, DOC and DIC exhibited also a strong spatial variation in C fluxes, with both dissolved C species decreasing from south to north. The rivers of the southern part of the plateau had the largest flow-weighted DOC concentrations among those previously reported for Siberian rivers, but the smallest flow-weighted DIC concentrations. In the study area, DOC and DIC fluxes were negatively correlated with the distribution of continuous permafrost and positively correlated with mean annual air temperature. A synthesis of literature data shows similar trends from west to east, with an eastward decrease of dissolved C concentrations and an increased proportion of DOC in the total dissolved C flux. It appears that there are two contemporary limitations for river export of terrigenous C across Siberia: (1) low productivity of ecosystems with respect to potentially mobilizable organic C, slow weathering rates with concomitant small formation of bicarbonate, and/or wildfire disturbance limit the pools of organic and inorganic C that can be mobilized for transport in rivers (source-limited), and (2) mobilization of available pools of C is constrained by low precipitation in the severe continental climate of interior Siberia (transport-limited). Climate warming may reduce the source limitation by enhancing primary production and weathering rates, while causes leading to surmounting the transport limitation remain debatable due to uncertainties in predictions of precipitation trends and other likely sources of reported increase of river discharges.

Аннотация: The peculiarities of organic carbon water soluble fraction content in the litters and soil profile in burned forests of different age under the cryolithozone conditions have been revealed. It has been shown that surface fires cause a decrease in the content of water-extractable organic carbon (WEOC) in the litters and upper 5 cm deep layer of soil. At the same time in microelevations these differences are more pronounced and the WEOC content in the upper organogenic horizons in burnt-out places is 2 times lower. In the deeper soil horizons there have been no differences detected in the WEOC content between intact plantations and postpyrogenic areas.

Аннотация: The postfire transformation of the functional activity of the microbial cenoses and the main soil properties under mixed larch forests were studied in the lower reaches of the Angara River. It was shown that the intensity of the postfire changes in the population density, biomass, and activity of the microorganisms in the dark podzolized brown forest soil depended on the degree of burning of the ground cover and the surface litter during the fire. The maximum effects of the fire on the microbial cenoses were observed in the litter and the upper 5-cm-thick layer of the dark-humus horizon in the areas of intense burning. The postfire restoration of the structural-functional activity of the microbial cenoses was determined by the degree of transformation of soil properties and by the postpyrogenic succession in the ground cover. The microbial complexes of the dark podzolized brown forest soils under mixed larch forests in the studied region restored their functional activity after the fires of different intensities quicker than the microbial cenoses of the sandy podzols in the pyrogenic lichen-green-moss pine forests of the same zone.
