: материалы временных коллективов / L. S. Shugalei // Tree species effects on soils: implications for global change. - 2005. - С. 257-268. - Библиогр. в конце ст.

Аннотация: The data obtained from this experimental plantation may be used for building mathematical models to predict soil response to changes in both climate and species composition.These changes would complicate the evaluation of the impact of individual tree species on soil properties, and novel techniques need to be developed.

    Aspen bark photosynthesis and its significance to remote sensing and carbon budget estimates in the boreal ecosystem
: материалы временных коллективов / V. I. Kharuk // Water, air & soil pollution. - 1995. - Vol. 82, № 1-2. - С. 483-497. - Библиогр. в конце ст.

Аннотация: Our findings have shown that the spectral characteristics of aspen bark differ considerably from the "grey body" representations typically utilised in radiative transfer models. Also, since the bark and leaf canopy fractions have different C assimilation capacities, the partitioning of canopy Chl into leaf and bark strata should improve C assimilation estimates. Remote sensing technology must be relied upon, especially in vast and largely in accessible regions such as the boreal biome, for landscape- and regional-scale studies of C budgets. In these studies, estimates of forest productivity and C exchange currently rely on spectral indices obtained from remote satellite/aircraft sensors; these spectral ratios are used to indirectly estimate C assimilation through correlation with chlorophyll and photosynthetic capacity.

    Evidence of evergreen conifer invasion into larch dominated forests during recent decades in Central Siberia
: материалы временных коллективов / V. I. Kharuk, K. Ranson, M. Dvinskaya // Eurasian Journal of Forest Research. - 2007. - Vol. 10-2. - С. 163-171. - Библиогр. в конце ст.

Аннотация: Models of climate warming predict the migration of "warm-adapted' species to habitates of "cold-adapted" species. Here we show evidence of expansion of "dark-needle" conifers (DNC: Siberian pine, spruce and fir) into the habitat of larch, the leader in adaptation to harsh climatic conditions in Asia. The studies were made along two transects oriented from the western and southern borders of a larch dominated forest to its center. The invasion of DNC into the historical larch habitat was quantified as an increase of the proportion of those species both in the overstory and in regeneration. The age structure of regeneration showed that regeneration occurred mainly during the last 2-3 decades. In particular warm winter temperatures promote the survival regenerated Siberian pine. The results obtained indicate the climate-driven migration of Siberian pine, spruce and fir into traditional zone of larch dominance. Substitution of a deciduous conifer (larch) by evergreen conifers decreases the albedo and may provide positive feedback for temperature increases.

    Potential change in lodgepole pine site index and distribution under climatic change in Alberta
: материалы временных коллективов / Robert A. Monserud [и др.] // Canadian Journal of Forest Research. - 2008. - Vol. 38, № 2. - С. 343-352. - Библиогр. в конце ст.

Аннотация: We estimated the impact of global climate change on lodgepole pine site productivity in Alberta based on the Alberts Climate Model and the A2 SRES climate change scenario projections from three global circulation models (CGCM2, HADCM3, and ECHAM4). Cosiderable warming ia apparent in all three models. On average, the increases in mean GDD5 (growing degree-day 5 degrees C) are 18%, 38%, and 65% by the 2020s, 2050s, respectively. Change in precipitation is essentially nil. This results in proportioanal increases in dryness index. We used the dryness index to predict the potential future range and GDD5 to predict its potential productivity.

    Climatic and geographic patterns of spatial distribution of precipitation in Siberia
: материалы временных коллективов / A. A. Onuchin, T. A. Burenina // Environmental change in Siberia: earth observation, field studies and modelling. - Dordrecht et. al. : Springer, 2010. - С. 193-210. - Библиогр. в конце ст.

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: This study analyses the Russian forest biomass -based bioenergy sector. It is shown that presently - although given abundant resources - the share of heat and electricity from biomass is very minor. With the help of 2 IIASA models, future green-field bioenergy plants are identified in a geographically explicit way. Resulkts indicate that by using only 3.3% of the total wood removals, twice as much heat and electricity that presently available from biomass could be generated. Furthermore, there is a multitude of co-benefits quantified for the socio-economic sector such as green jobs linked to bioenergy.

Аннотация: An emperical fire study, using 2 to 4-ha experimental burn plots, was conducted in Central Siberia to obtain data to develop fire behaviour models for Scots pine forests. Fuel consumptiuon (depth of burn and fuel consumption) was predicted using the Russian Moisture Index (PV-1) or the Canadian Forest Fire Weather Index (FWI) System. However, only the FWI System could be used to model fire behaviour characteristics (rate of spread and fireline intensity), as wind speed is an important input factor in its calculatiion and is not accounted for in the PV-1.

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.

forest stands -- windfall -- successions -- competition models

Аннотация: Based on the concept of competition for resources, the distribution of trees upon reforestation in windfall areas is studied. As a theoretical model for competition, a Zipf-Pareto model of ranking the distribution of resources is used. Analysis shows that the processes resulting from competitive interactions between the trees of different species proceed slowly in a windfall area where coniferous species get replaced by deciduous ones. In the territory where deciduous species initially dominated, competitive interactions between trees of different species turn out to be formed almost immediately upon natural reforestation after the windfall. By the time the ratio of species stabilizes and becomes a steady state, the ranks of individual species also stabilize. This result is obtained on the basis of a quantitative assessment of the change in leadership between competing species in time using Spearman's rank correlation coefficient.

Аннотация: We determine the net land to atmosphere flux of carbon in Russia, including Ukraine, Belarus and Kazakhstan, using inventory-based, eddy covariance, and inversion methods. Our high boundary estimate is -342 TgC yr(-1) from the eddy covariance method, and this is close to the upper bounds of the inventory-based Land Ecosystem Assessment and inverse models estimates. A lower boundary estimate is provided at -1350 TgC yr(-1) from the inversion models. The average of the three methods is -613.5 TgC yr(-1). The methane emission is estimated separately at 41.4 Tg C yr(-1). These three methods agree well within their respective error bounds. There is thus good consistency between bottom-up and top-down methods. The forests of Russia primarily cause the net atmosphere to land flux (-692 TgC yr(-1) from the LEA. It remains however remarkable that the three methods provide such close estimates (-615, -662, -554 TgC yr(-1)) for net biome production (NBP), given the inherent uncertainties in all of the approaches. The lack of recent forest inventories, the few eddy covariance sites and associated uncertainty with upscaling and undersampling of concentrations for the inversions are among the prime causes of the uncertainty. The dynamic global vegetation models (DGVMs) suggest a much lower uptake at -91 TgC yr(-1), and we argue that this is caused by a high estimate of heterotrophic respiration compared to other methods.

climate warming -- bioclimatic models -- major conifer ranges -- Central Siberia

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: 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.

climate warming -- central Siberia -- agriculture -- crop range and production

Аннотация: Humans have traditionally cultivated steppe and forest-steppe on fertile soils for agriculture. Forests are predicted to shift northwards in a warmer climate and are likely to be replaced by forest-steppe and steppe ecosystems. We analyzed potential climate change impacts on agriculture in south-central Siberia believing that agriculture in traditionally cold Siberia may benefit from warming. Simple models determining crop range and regression models determining crop yields were constructed and applied to climate change scenarios for various time frames: pre-1960, 1960-90 and 1990-2010 using historic data and data taken from 2020 and 2080 HadCM3 B1 and A2 scenarios. From 50 to 85% of central Siberia is predicted to be climatically suitable for agriculture by the end of the century, and only soil potential would limit crop advance and expansion to the north. Crop production could increase twofold. Future Siberian climatic resources could provide the potential for a great variety of crops to grow that previously did not exist on these lands. Traditional Siberian crops could gradually shift as far as 500 km northwards (about 50-70 km/decade) within suitable soil conditions, and new crops nonexistent today may be introduced in the dry south that would necessitate irrigation. Agriculture in central Siberia would likely benefit from climate warming. Adaptation measures would sustain and promote food security in a warmer Siberia.
