    Climatic changes, successions of peatlands and zonal vegetation, and peat accumulation dynamics in the Holocene (the West-Siberia peat profile "Vodorosdel")
/ F.Z. Glebov // Climatic Change. - 2002. - Vol. 55, № 1-2. - С. 175-181

Аннотация: The developmental history of peatland and dry land vegetation within the Ob-Vasugan watershed of Western Siberia was characterized according to features of the plant communities and climatic changes which were revealed by stratigraphic, spore-pollen and C-14 (carbon) data obtained from a vertical peat profile 'Vodorasdel'. Changes in the paleoecological environment over the last 10000 years were divided into five periods. The climate was characterized in the Holocene according to these periods. At the watershed studied, peatland-forming processes started about 9510 years ago resulting in 550 cm of peat accumulation. The rate of peat accumulation within the watershed decreased over time from 1.9-0.3 mm year(-1).

Аннотация: Thermokarst wetlands and ponds in the subarctic, which are located in land surface depressions resulting from permafrost melt, are strong sources of CH4, but little is known about respiration processes supporting these emissions. We determined CH4 fluxes and concentration profiles of dissolved gases and anions and some delta C-13 ratios of CO2 and CH4 in a thermokarst pond and adjacent smaller thermokarst depressions in the forest tundra near Igarka, northern Siberia in August 2006. Methane was emitted at 110-170 mg m(-2) d(-1) and produced mostly by CO2 reduction, which also provided high Gibbs free energies on the order of 50-70 KJ mol(-1) H-2 due to high H-2 concentrations. The diffusive flux calculated from CH4 gradients in the floating mat contributed 2% to emissions. CH4 was apparently not oxidized deeper than 20 cm into the floating mat and the water body below. Anaerobic respiration required to reproduce nonsteady state CO2 concentration maxima in the floating mat above the water body was 30-80 nmol cm(-3) d(-1) or 250 mg m(-2) d(-1) and thus on a similar order of magnitude as CH4 fluxes. The results suggest that floating mat-covered thermokarst ponds located in northern Siberian bogs effectively convert recently fixed carbon into CH4 and thus allow for emissions independently from the finite, bog-derived carbon source. The relative contribution of recently fixed and old bog-derived carbon to C fluxes requires further investigation, however.

    Interpretation of radiocarbon data on the age of different structural elements of a naturally drained peatland
[Text] / T. T. Efremova, S. P. Efremov, L. A. Orlova // Eurasian Soil Sci. - 2003. - Vol. 36, Is. 10. - P1037-1044. - Cited References: 25 . - 8. - ISSN 1064-2293
РУБ Soil Science

Аннотация: The degree of aggregation of peat substrate and the size of structural elements can be used to distinguish between different stages of a peatland evolution and characterize relic features in the profile of modern peat soil. Carbon fractions separated from different aggregates are indicative of the age of peat accumulated in the period of active growth of the peatland and of the age of peat transformed during the peatland drying. On the basis of these data, annual rates of peat growth at different evolution stages can be determined, as well as the rates of organic carbon sequestration and the amount of peat forming from plant remains.

    Denitrification potential andCO(2) emission in the northern forest soils of the Yenisei meridian (the Siberian IGBP transect)
[Text] / O. V. Menyailo, Y. N. Krasnoshchekov // Biol. Bull. - 2003. - Vol. 30, Is. 3. - P299-303, DOI 10.1023/A:1023872215777. - Cited References: 20 . - 5. - ISSN 1062-3590
РУБ Biology

Аннотация: To estimate the probable contribution of northern forest soils to the global budget of greenhouse microgases. the cryogenic soils along the Yenisei meridian have been studied with respect to their potential denitrification and carbon mineralization activities. It is shown that the forest soils of the boreal zone have a high denitrification potential and, under conditions of a high nitrate nitrogen content, may be a source of nitrous c oxide emission. A significant correlation is observed between N2O and CO2 emissions (r = 0.85, p 0.001).

    Comparative ecosystem-atmosphere exchange of energy and mass in a European Russian and a central Siberian bog II. Interseasonal and interannual variability of CO2 fluxes
[Text] / A. . Arneth [et al.] // Tellus Ser. B-Chem. Phys. Meteorol. - 2002. - Vol. 54, Is. 5. - P514-530, DOI 10.1034/j.1600-0889.2002.01349.x. - Cited References: 53 . - 17. - ISSN 0280-6509
РУБ Meteorology & Atmospheric Sciences

Аннотация: Net ecosystem-atmosphere exchange of CO2 (NEE) was measured in two boreal bogs during the snow-free periods of 1998, 1999 and 2000. The two sites were located in European Russia (Fyodorovskoye), and in central Siberia (Zotino). Climate at both sites was generally continental but with more extreme summer-winter gradients in temperature at the more eastern site Zotino. The snow-free period in Fyodorovskoye exceeded the snow-free period at Zotino by several weeks. Marked seasonal and interannual differences in NEE were observed at both locations, with contrasting rates and patterns. Amongst the most important contrasts were: (1) Ecosystem respiration at a reference soil temperature was higher at Fyodorovskoye than at Zotino. (2) The diurnal amplitude of summer NEE was larger at Fyodorovskoye than at Zotino. (3) There was a modest tendency for maximum 24 h NEE during average rainfall years to be more negative at Zotino (-0.17 versus -0.15 mol m(-2) d(-1)), suggesting a higher productivity during the summer months. (4) Cumulative net uptake of CO2 during the snow-free period was strongly related to climatic differences between years. In Zotino the interannual variability in climate, and also in the CO2 balance during the snow-free period, was small. However, at Fyodorovskoye the bog was a significant carbon sink in one season and a substantial source for CO2-C in the next, which was below-average dry. Total snow-free uptake and annual estimates of net CO2-C uptake are discussed, including associated uncertainties.

    The Holocene dynamics of vegetation and the upper forest limit in the Polar Urals
[Text] / V. L. Koshkarova, L. V. Karpenko, L. A. Orlova // Russ. J. Ecol. - 1999. - Vol. 30, Is. 2. - P102-106. - Cited References: 16 . - 5. - ISSN 1067-4136
РУБ Ecology

Аннотация: The species structure of forest vegetation and climate in the Holocene was reconstructed on the basis of analysis of macroscopic plant remnants, botanical analysis of peat, and radiocarbon dating performed in the Polar Ural peatland (Mount Rai-Iz). The results showed that the upper forest limit repeatedly migrated upward for 220-400 m in the periods of:warming and retreated during cold periods. Brief cold periods proved to cause abrupt changes in the composition of tree species as more dynamic plants.

    Productivity of mosses and organic matter accumulation in the litter of sphagnum larch forest in the permafrost zone
[Text] / A. S. Prokushkin [et al.] // Russ. J. Ecol. - 2006. - Vol. 37, Is. 4. - P225-232, DOI 10.1134/S1067413606040023. - Cited References: 35 . - 8. - ISSN 1067-4136
РУБ Ecology

Аннотация: Productivity of the moss cover and necromass accumulation in the litter of a sphagnum larch forest have been estimated on the basis of tree age. It has been shown that the total carbon stock in the litter of a 100-year-old stand, including organic matter not destroyed by fire, exceeds the corresponding value for the tree stand itself by more than,an order of magnitude. The accumulation of organic matter on the soil surface inhibits the growth of larch. In particular, this factor impairs hydrothermal conditions in the soil and causes a rise of the permafrost table; as a consequence, lower layers of the root system die off.

Аннотация: Na, Br, Cs, Ca, Mg, Ba, Cl and Br distribution along the profile of peatland in the process of peat accumulation is regulated by the climatic fluctuation during Holocene. The possibility of using this information for paleoclimate reconstruction has been shown. In all probability it can be considered as the biochemical migration of alkali-earth and alkaline metals in the process of peat formation reflects mainly climatic fluctuations, connected with temperature, and halogens - with moistening factor.

Аннотация: The ecosystems in Northern Eurasia (NE) play an important role in the global water cycle and the climate system. While evapotranspiration (ET) is a critical variable to understand this role, ET over this region remains largely unstudied. Using an improved version of the Terrestrial Ecosystem Model with five widely used forcing data sets, we examine the impact that uncertainties in climate forcing data have on the magnitude, variability, and dominant climatic drivers of ET for the period 1979-2008. Estimates of regional average ET vary in the range of 241.4-335.7mmyr(-1) depending on the choice of forcing data. This range corresponds to as much as 32% of the mean ET. Meanwhile, the spatial patterns of long-term average ET across NE are generally consistent for all forcing data sets. Our ET estimates in NE are largely affected by uncertainties in precipitation (P), air temperature (T), incoming shortwave radiation (R), and vapor pressure deficit (VPD). During the growing season, the correlations between ET and each forcing variable indicate that T is the dominant factor in the north and P in the south. Unsurprisingly, the uncertainties in climate forcing data propagate as well to estimates of the volume of water available for runoff (here defined as P-ET). While the Climate Research Unit data set is overall the best choice of forcing data in NE according to our assessment, the quality of these forcing data sets remains a major challenge to accurately quantify the regional water balance in NE.

Аннотация: Climate warming increases evapotranspiration (ET) more in boreal peatlands than in forests. Observations show that peatland ET can exceed forest ET by up to 30%, indicating a stronger warming response in peatlands. Earth system models do not fully account for peatlands and hence may underestimate future boreal ET. The response of evapotranspiration (ET) to warming is of critical importance to the water and carbon cycle of the boreal biome, a mosaic of land cover types dominated by forests and peatlands. The effect of warming-induced vapour pressure deficit (VPD) increases on boreal ET remains poorly understood because peatlands are not specifically represented as plant functional types in Earth system models. Here we show that peatland ET increases more than forest ET with increasing VPD using observations from 95 eddy covariance tower sites. At high VPD of more than 2 kPa, peatland ET exceeds forest ET by up to 30%. Future (2091-2100) mid-growing season peatland ET is estimated to exceed forest ET by over 20% in about one-third of the boreal biome for RCP4.5 and about two-thirds for RCP8.5. Peatland-specific ET responses to VPD should therefore be included in Earth system models to avoid biases in water and carbon cycle projections.

Аннотация: The response of evapotranspiration (ET) to warming is of critical importance to the water and carbon cycle of the boreal biome, a mosaic of land cover types dominated by forests and peatlands. The effect of warming-induced vapour pressure deficit (VPD) increases on boreal ET remains poorly understood because peatlands are not specifically represented as plant functional types in Earth system models. Here we show that peatland ET increases more than forest ET with increasing VPD using observations from 95 eddy covariance tower sites. At high VPD of more than 2 kPa, peatland ET exceeds forest ET by up to 30%. Future (2091–2100) mid-growing season peatland ET is estimated to exceed forest ET by over 20% in about one-third of the boreal biome for RCP4.5 and about two-thirds for RCP8.5. Peatland-specific ET responses to VPD should therefore be included in Earth system models to avoid biases in water and carbon cycle projections. © 2020, The Author(s), under exclusive licence to Springer Nature Limited.

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.

    Temperature control of spring CO2 fluxes at a coniferous forest and a peat bog in central Siberia
/ S.-B. Park, A. Knohl, M. Migliavacca [et al.] // Atmosphere. - 2021. - Vol. 12, Is. 8. - Ст. 984, DOI 10.3390/atmos12080984 . - ISSN 2073-4433
Аннотация: Climate change impacts the characteristics of the vegetation carbon-uptake process in the northern Eurasian terrestrial ecosystem. However, the currently available direct CO2 flux measurement datasets, particularly for central Siberia, are insufficient for understanding the current condition in the northern Eurasian carbon cycle. Here, we report daily and seasonal interannual variations in CO2 fluxes and associated abiotic factors measured using eddy covariance in a coniferous forest and a bog near Zotino, Krasnoyarsk Krai, Russia, for April to early June, 2013–2017. Despite the snow not being completely melted, both ecosystems became weak net CO2 sinks if the air temperature was warm enough for photosynthesis. The forest became a net CO2 sink 7–16 days earlier than the bog. After the surface soil temperature exceeded ~1?C, the ecosystems became persistent net CO2 sinks. To change into the full spring photosynthesis recovery, the forest is likely to need a minimum accumulated air temperature of ~80 to 137?C, and the bog requires 141 to 211?C. During these periods, soil temperature in the forest still remained nearly 0?C, suggesting that it is likely that forests appear more sensitive to the rise of air temperature than bogs. Net ecosystem productivity was highest in 2015 for both ecosystems because of the anomalously high air temperature in May compared with other years. Our findings demonstrate that long-term monitoring of flux measurements at the site level, particularly during winter and its transition to spring, is essential for understanding the responses of the northern Eurasian ecosystem to spring warming. © 2021 by the authors.

Аннотация: For the first time, using the example of a key object of the peat river valleys of the Kuznetsk Alatau occupied by spruce forests, it is shown that swamp waters are clearly differentiated by the content of the main ions due to forest-peat fires. Swamp waters objectively form three groups: (1) waters of the original type of mineral nutrition (fresh, soft), (2) waters of peatland covered by a medium fire (fresh, hard), (3) waters of peatland covered by a high fire (slightly saline, very hard). Magnesium ions and bicarbonates have the highest discriminating power (95%) in the determination of swamp waters. The swamp waters of the post-pyrogenic peatland do not lose the ratio of the main ions, which is similar to waters of the original type, and retain the hydro-carbonate calcium-magnesium composition.
