Аннотация: While the forest-tundra zone in Siberia, Russia has been dendroclimatologically well-studied in recent decades, much less emphasis has been given to a wide belt of northern taiga larch forests located to the south. In this study, climate and local site conditions are explored to trace their influence on radial growth of Gmelin larch (Larix gmelinii (Rupr.) Rupr.) trees developed on permafrost soils in the northern taiga. Three dendrochronological sites characterized by great differences in thermo-hydrological regime of soils were established along a short (ca. 100 m long) transect: on a river bank (RB), at riparian zone of a stream (RZ) and on a terrace (TER). Comparative analysis of the rate and year-to-year dynamics of tree radial growth among sites revealed considerable difference in both raw and standardized tree-ring width (TRW) chronologies obtained for the RZ site, characterized by shallow soil active layer depth and saturated soils. Results of dendroclimatic analysis indicated that tree-ring growth at all the sites is mostly defined by climatic conditions of a previous year and precipitation has stronger effect on TRW chronologies in comparison to the air temperatures. Remarkably, a great difference in the climatic response of TRW chronologies has been obtained for trees growing within a very short distance from each other. The positive relation of tree-ring growth with precipitation, and negative to temperature was observed in the dry site RB. In contrary, precipitation negatively and temperature positively influenced tree radial growth of larch at the water saturated RZ. Thus, a complicate response of northern Siberian larch forest productivity to the possible climate changes is expected due to great mosaic of site conditions and variability of environmental factors controlling tree-ring growth at different sites. Our study demonstrates the new possibilities for the future dendroclimatic research in the region, as various climatic parameters can be reconstructed from tree-ring chronologies obtained for different sites.

Аннотация: Fluxes of dissolved organic matter (DOM) in larch biogeocenoses and its export from the drainage basin have been studied in the zone of continuous permafrost. A comparative assessment of DOM input into the soil has been made on slopes of northern and southern exposures (as variants reflecting the current state and warming). The dynamics of DOM export in a creek depending on the increasing depth of the active soil horizon in the drainage area have been revealed. It is concluded that an increase in the depth of the seasonally thawing layer induced by global warming will not have any significant effect on the amount of annual DOM export. Reduction of DOM export may be expected upon a decrease in litter stocks under the effect of their mineralization and forest fires.

Аннотация: We investigated isotopic signature of methane efflux from soil surface of Siberian arctic and sub-arctic ecosystems in sites in Siberia. In the boreal ecosystem of the Tura site (64 degrees 15'N, 100 13'E) the delta C-13 signature of methane (-43%o for south facing slope and -35%o from north facing slope) showed low methane production potential of investigated soils. Two years of monitoring of the delta C-13(CH4) signatures from surface of ice-wedge polygon of Samoylov island (72 degrees 22'N, 126 degrees 28'E) showed that the delta C-13 signature were different regarding to temperature and precipitation. The mean of delta C-13(CH4) emitted from the polygon wall ranged from 72.5 +/- 1.9%. to-47.3 +/- 1.5%. The same for polygon center ranged from-67.1 +/- 2.0% to-62.4 +/- 1.7%. Almost no difference between delta C-13(CH4) signature of years observed could mean that conditions for methane production are possibly quite stable. With respect to methane emission both permafrost ecosystems are thus very contrasting.

Аннотация: The permafrost region represents about 25% of the northern hemisphere (23x10(6) km(2)) and covers about 63% of the area of the Russian Federation (10x10(6) km(2)). Arctic and sub-arctic territories are particularly sensitive to temperature variations. Permafrost ground temperature has increased by 0.3-2.0 degrees C in northern Russia during the last four decades. This will result in permafrost thawing and changes in water balance. Until 2050, the thaw depth in the northern part of Siberia could increase by more than 50%. The remote sensing technique is useful in the studies of permafrost area. Remotely sensed gravity measurements from the GRACE (Gravity Recovery and Climate Experiment) mission allowed identifying of significant decrease of water mass in ice regions. The aim of this investigation was to reveal relationships between active layer changes and water mass anomalies extracted from GRACE data in the cryolithozone of Central Siberia. Six test sites with available active layer data were investigated. Correlation analysis was carried out to determine relationships of the thaw depth with equivalent water thickness anomalies (EWTA). June EWTA significantly correlates with the thaw depth in July on the Samoilov Island (r = 0.82, p < 0.03). This means that an increasing amount of water in soil results in a better transfer of heat to the frozen soils, thus can result in thawing at greater depth. Depending on site mean thaw depth values positively correlates with April, May, June and August EWTA (r = 0.72-0.98, p < 0.05). For Igarka site, the negative correlation of thaw depth in September with August EWTA was revealed (r = -0.99, p < 0.1). This is opposed to the observed on Samoilov Island, and probably, explained by differences in hydrological regimes.

Аннотация: Peatlands and forests cover large areas of the boreal biome and are critical for global climate regulation. They also regulate regional climate through heat and water vapour exchange with the atmosphere. Understanding how land-atmosphere interactions in peatlands differ from forests may therefore be crucial for modelling boreal climate system dynamics and for assessing climate benefits of peatland conservation and restoration. To assess the biophysical impacts of peatlands and forests on peak growing season air temperature and humidity, we analysed surface energy fluxes and albedo from 35 peatlands and 37 evergreen needleleaf forests-the dominant boreal forest type-and simulated air temperature and vapour pressure deficit (VPD) over hypothetical homogeneous peatland and forest landscapes. We ran an evapotranspiration model using land surface parameters derived from energy flux observations and coupled an analytical solution for the surface energy balance to an atmospheric boundary layer (ABL) model. We found that peatlands, compared to forests, are characterized by higher growing season albedo, lower aerodynamic conductance, and higher surface conductance for an equivalent VPD. This combination of peatland surface properties results in a similar to 20% decrease in afternoon ABL height, a cooling (from 1.7 to 2.5 degrees C) in afternoon air temperatures, and a decrease in afternoon VPD (from 0.4 to 0.7 kPa) for peatland landscapes compared to forest landscapes. These biophysical climate impacts of peatlands are most pronounced at lower latitudes (similar to 45 degrees N) and decrease toward the northern limit of the boreal biome (similar to 70 degrees N). Thus, boreal peatlands have the potential to mitigate the effect of regional climate warming during the growing season. The biophysical climate mitigation potential of peatlands needs to be accounted for when projecting the future climate of the boreal biome, when assessing the climate benefits of conserving pristine boreal peatlands, and when restoring peatlands that have experienced peatland drainage and mining.
