Аннотация: Net ecosystem productivity (NEP) was studied in a bog located in the middle taiga of Siberia using two approaches, the accumulation of peat above the hypocotyl of pine trees, and the eddy covariance flux methodology. NEP was 0.84 tC ha(-1) yr(-1) using the peat accumulation method; it was 0.43-0.62 tC ha(-1) yr(-1) using eddy covariance over three growing seasons. These data were compared with NEP of the surrounding forest, which was 0.6 tC +/- 1.1 hat yr(-1). The trees growing on the bog reached a total height of about 3 m and an age of 80-120 yr when peat accumulation reached 0.5-0.6 m. At that stage the growth rate of the oldest trees declined. This indicates that there is a maximum age that can be reached by trees growing on hummocks (150 yr), depending on conditions. The data show that the determination of NEP in bogs by using the peat accumulation above the hypocotyl is a useful method which can be applied on a wide range of bog types, but it may systematically overestimate NEP. The total sink capacity for carbon assimilation of bogs is comparable to that of forest, although methane emissions and losses of dissolved organic carbon must be taken into account when assessing the regional carbon cycle.

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.

Аннотация: Plant species exert strong effects on ecosystem functions and one of the emerging, and difficult to test hypotheses, is that plants alter soil functions through changing the community structure of soil microorganisms. We tested the hypothesis for atmospheric CH4 oxidation by using soil samples from a Siberian afforestation experiment and exposing them to C-13-CH4. We determined the activity of the soil methanotrophs under different tree species at three levels of initial CH4 concentration (30, 200 and 1000 ppm) thus distinguishing the activities of low- and high-affinity methanotrophs. Half of the samples were incubated with C-13-enriched CH4 (99.9%) and half with C-12-CH4. This allowed an estimation of the amount of C-13 incorporated into individual PLFAs and determination of PLFAs of methanotrophs involved in CH4 oxidation at the different CH4 concentrations. Tree species strongly altered the activity of atmospheric CH4 oxidation without appearing to change the composition of high-affinity methanotrophs as evidenced by PLFA C-13 labeling. The low diversity of atmospheric CH4 oxidizers, presumably belonging to the UCS alpha group, may explain the lack of tree species effects on the composition of soil methanotrophs. We submit that the observed tree species effects on atmospheric CH4 oxidation indicate an effect on biomass or cell-specific activities rather than by a community change and this may be related to the impact of the tree species on soil N cycling.

Аннотация: We present first results from 19 months of semicontinuous concentration measurements of biogeochemical trace gases (CO2, CO, and CH4) and O-2, measured at the Zotino Tall Tower Observatory (ZOTTO) in the boreal forest of central Siberia. We estimated CO2 and O2 seasonal cycle amplitudes of 26.6 ppm and 134 per meg, respectively. An observed west-east gradient of about -7 ppm (in July 2006) between Shetland Islands, Scotland, and ZOTTO reflects summertime continental uptake of CO2 and is consistent with regional modeling studies. We found the oceanic component of the O-2 seasonal amplitude (Atmospheric Potential Oxygen, or APO) to be 51 per meg, significantly smaller than the 95 per meg observed at Shetlands, illustrating a strong attenuation of the oceanic O-2 signal in the continental interior. Comparison with the Tracer Model 3 (TM3) atmospheric transport model showed good agreement with the observed phasing and seasonal amplitude in CO2; however, the model exhibited greater O-2 (43 per meg, 32%) and smaller APO (9 per meg, 18%) amplitudes. This seeming inconsistency in model comparisons between O-2 and APO appears to be the result of phasing differences in land and ocean signals observed at ZOTTO, where ocean signals have a significant lag. In the first 2 months of measurements on the fully constructed tower (November and December 2006), we observed several events with clear vertical concentration gradients in all measured species except CO. During "cold events'' (below -30 degrees C) in November 2006, we observed large vertical gradients in CO2 (up to 22 ppm), suggesting a strong local source. The same pattern was observed in CH4 concentrations for the same events. Diurnal vertical CO2 gradients in April to May 2007 gave estimates for average nighttime respiration fluxes of 0.04 +/- 0.02 mol C m(-2) d(-1), consistent with earlier eddy covariance measurements in 1999-2000 in the vicinity of the tower.

Аннотация: Terrestrial ecosystems in northern high latitudes exchange large amounts of methane (CH4) with the atmosphere. Climate warming could have a great impact on CH4 exchange, in particular in regions where degradation of permafrost is induced. In order to improve the understanding of the present and future methane dynamics in permafrost regions, we studied CH4 fluxes of typical landscape structures in a small catchment in the forest tundra ecotone in northern Siberia. Gas fluxes were measured using a closed-chamber technique from August to November 2003 and from August 2006 to July 2007 on tree-covered mineral soils with and without permafrost, on a frozen bog plateau, and on a thermokarst pond. For areal integration of the CH4 fluxes, we combined field observations and classification of functional landscape structures based on a high-resolution Quickbird satellite image. All mineral soils were net sinks of atmospheric CH4. The magnitude of annual CH4 uptake was higher for soils without permafrost (1.19 kg CH4 ha(-1) yr(-1)) than for soils with permafrost (0.37 kg CH4 ha(-1) yr(-1)). In well-drained soils, significant CH4 uptake occurred even after the onset of ground frost. Bog plateaux, which stored large amounts of frozen organic carbon, were also a net sink of atmospheric CH4 (0.38 kg CH4 ha(-1) yr(-1)). Thermokarst ponds, which developed from permafrost collapse in bog plateaux, were hot spots of CH4 emission (approximately 200 kg CH4 ha(-1) yr(-1)). Despite the low area coverage of thermokarst ponds (only 2.1% of the total catchment area), emissions from these sites resulted in a mean catchment CH4 emission of 3.8 kg CH4 ha(-1) yr(-1). Export of dissolved CH4 with stream water was insignificant. The results suggest that mineral soils and bog plateaux in this region will respond differently to increasing temperatures and associated permafrost degradation. Net uptake of atmospheric CH4 in mineral soils is expected to gradually increase with increasing active layer depth and soil drainage. Changes in bog plateaux will probably be much more rapid and drastic. Permafrost collapse in frozen bog plateaux would result in high CH4 emissions that act as positive feedback to climate warming.

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.

Аннотация: Forest ecosystems assimilate more CO(2) from the atmosphere and store more carbon in woody biomass than most nonforest ecosystems, indicating strong potential for afforestation to serve as a carbon management tool. However, converting grasslands to forests could affect ecosystem-atmosphere exchanges of other greenhouse gases, such as nitrous oxide and methane (CH(4)), effects that are rarely considered. Here, we show that afforestation on a well-aerated grassland in Siberia reduces soil CH(4) uptake by a factor of 3 after 35 years of tree growth. The decline in CH(4) oxidation was observed both in the field and in laboratory incubation studies under controlled environmental conditions, suggesting that not only physical but also biological factors are responsible for the observed effect. Using incubation experiments with (13)CH(4) and tracking (13)C incorporation into bacterial phospholipid fatty acid (PLFA), we found that, at low CH(4) concentrations, most of the (13)C was incorporated into only two PLFAs, 18 : 1 omega 7 and 16 : 0. High CH(4) concentration increased total (13)C incorporation and the number of PLFA peaks that became labeled, suggesting that the microbial assemblage oxidizing CH(4) shifts with ambient CH(4) concentration. Forests and grasslands exhibited similar labeling profiles for the high-affinity methanotrophs, suggesting that largely the same general groups of methanotrophs were active in both ecosystems. Both PLFA concentration and labeling patterns indicate a threefold decline in the biomass of active methanotrophs due to afforestation, but little change in the methanotroph community. Because the grassland consumed CH(4) at a rate five times higher than forest soils under laboratory conditions, we concluded that not only biomass but also cell-specific activity was higher in grassland than in afforested plots. While the decline in biomass of active methanotrophs can be explained by site preparation (plowing), inorganic N (especially NH(4)(+)) could be responsible for the change in cell-specific activity. Overall, the negative effect of afforestation of upland grassland on soil CH(4) uptake can be largely explained by the reduction in biomass and to a lesser extent by reduced cell-specific activity of CH(4)-oxidizing bacteria.

Аннотация: Changes in tree species composition could affect how forests produce and consume greenhouse gases, because the soil microorganisms that carry out these biogeochemical transformations are often sensitive to plant characteristics. We examined the effects of thirty years of stand development under six tree species in Siberian forests (Scots pine, spruce, arolla pine, larch, aspen and birch) on potential rates Of Soil CO2 production, N2O reduction and N2O production during denitrification, and CH4 oxidation. Because many of these activities relate to soil N turnover, we also measured net nitrification and N mineralization. Overall, the effects of tree species were more pronounced on N2O and CH4 fluxes than on CO2 production. Tree species altered substrate-induced respiration (SIR) and basal respiration, but the differences were not as large as those observed for N transformations. Tree species caused similar effects on denitrification potential, net N mineralization, and net nitrification, but effects on N2O reduction were idiosyncratic, resulting in a decoupling of N2O production and reduction. CH4 oxidation was affected by tree species, but these effects depended on soil moisture: increasing soil moisture enhanced CH4 oxidation under some tree species but decreased it under others. If global warming causes deciduous species to replace coniferous species, our results suggest that Siberian forests would support soil microbial communities with enhanced potential to consume CH4 but also to produce more N2O. Future predictions of CH4 uptake and N2O efflux in boreal and temperate forests need to consider changes in tree species composition together with changes in soil moisture regimes.

Аннотация: Methane consumption by temperate forest soils is a major sink for this important greenhouse gas, but little is known about how tree species influence CH4 uptake by soils. Here, we show that-six common tree species in Siberian boreal and temperate forests significantly affect potential CH4 consumption in laboratory microcosms. Overall, soils under hardwood species (aspen and birch) consumed CH4 at higher rates than soils under coniferous species and grassland. While NH4+ addition often reduces CH4 uptake, we found no effect of NH(4)(+)addition, possibly because of the relatively high ratio of CH4-to-NH4+ in our incubations. The effects of soil moisture strongly depended on plant species. An increase in soil moisture enhanced CH4 consumption in soils under spruce but had the opposite effect under Scots pine and larch. Under other species, soil moisture did not affect CH4 consumption. These results could be explained by specific responses of different groups of CH4-oxidizing bacteria to elevated moisture.

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: 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 ?13C ratios of CO 2 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 H2 due to high H2concentrations. The diffusive flux calculated from CH 4 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 CH 4 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. Copyright 2008 by the American Geophysical Union.

Аннотация: Forest soils are generally sinks of CH4 and sources of N2O. To characterize the dynamics of these major greenhouse gases in central Siberia during the growing season, we measured fluxes from forest soil and assessed the relationships between CH4 and N2O fluxes and forest floor vegetation types, soil temperature, and moisture conditions. At the soil surface, both CH4 uptake and emission (-6.6 to 3.1В ?g CH4-CВ m-2В h-1) were observed, and CH4 fluxes did not differ among vegetation types. CH4 flux was positively correlated with soil moisture, but not with soil temperature. The small CH4 uptake compared with previous reports was due to CH4 production in response to high precipitation. N2O was also emitted and taken up by soil (-0.2 to 0.4В ?gВ N2O-NВ m-2В h-1), and N2O fluxes did not differ among vegetation types. N2O flux was negatively correlated with soil moisture and not correlated with soil temperature. Our findings suggest that high soil moisture and low availability of mineral nitrogen resulted in N2O uptake due to denitrification. Furthermore, both CH4 and N2O were emitted from a river at the site; these were produced in the basin of the riverbank rather than deep in the soil. В© 2014 Elsevier B.V. and NIPR.

Аннотация: Methane (CH4) production, oxidation, and emission were studied in ponds of the permafrost-affected polygonal tundra in northeast Siberia. Microbial degradation of organic matter in water-saturated soils is the most important source for the climate-relevant trace gas CH4. Although ponds and lakes cover a substantial fraction of the land surface of northern Siberia, data on CH4 fluxes from these water bodies are scarce. Summer CH4 fluxes were measured with closed chambers at the margins of ponds vegetated by vascular plants and in their centers without vascular plants. Furthermore, CH4 and oxygen concentration gradients, stable carbon isotope signatures of dissolved and emitted CH4, and microbial CH4 production and CH4 oxidation were determined. Mean summer fluxes were significantly higher at the margins of the ponds (46.1 ± 15.4 mg CH4 m-2 d-1) than at the centers (5.9 ± 8.2 mg CH4 m-2 d-1). CH4 transport was dominated by diffusion in most open water sites, but substantial ebullitive fluxes (12.0 ± 8.1 mg CH4 m-2 d-1) were detected in one pond. Plant-mediated transport accounted for 70 to 90% of total CH4 fluxes above emerged vegetation. In the absence of vascular plants, 61 to 99% of the CH4 produced in the anoxic bottom soil was consumed in a layer of the submerged moss Scorpidium scorpioides, which covered the bottoms of the ponds. The fraction of CH4 oxidized was lower at sites with vascular plants since CH4 was predominantly transported through their aerenchyma, thereby bypassing the CH4 oxidation zone in the moss layer. These results emphasize the importance of moss-associated CH4 oxidation causing low CH4 fluxes from the studied Siberian ponds. © 2015. American Geophysical Union. All Rights Reserved.

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: It has been found that the total productivity of bacteria and micromycetes in the 0- to 50-cm layer of homogeneous cryozems (Cryosols) on slopes of northern and southern exposures varies from 1.2 to 1.4 t/ha, respectively, and the calculated content of microbial carbon varies in the range 0.7-0.9 t/ha. The respiratory activity of the upper soil layer is 2.5-2.6 mu g C-CO2/(g h); the potential methane formation capacity reaches 0.13 nmol CH4/(m(2) day) for soils on slopes of northern exposure and 0.16 nmol CH4/(m(2) day) for slopes of southern exposure. Accumulation of sorbed ammonium is recorded in the range 15-17 mg NH4/100 g soil in summer. The increase of temperature in the upper horizons of soils on slopes of southern exposure by 5A degrees C compared to the northern slopes results in only an insignificant increase in the emission of CO2 and CH4. The accumulation of sorbed ammonium and nitrate nitrogen in homogeneous cryozems during the vegetation period is comparable to that in gray forest soils of the southern taiga subzone of the Middle Siberia.

Аннотация: Проведены исследования структуры, динамики и функциональной (биогеохимической) активности микробных комплексов криогенных почв лиственничников Центральной Эвенкии и полигональной тундры дельты р. Лена (остров Самойловский). Установлено, что суточное выделение метана с поверхности почвы лесной экосистемы в 3-5 раза ниже, чем в центре морозобойного полигона тундры. Экспериментальное кратковременное прогревание мерзлотного горизонта почвы до 18.5-22.5 °С в лиственничнике привело к нейтрализации почвенного раствора, уменьшению численности всех эколого-трофических групп микроорганизмов и значений микробной биомассы а также к увеличению эмиссии парниковых газов СО2 и СН4 в атмосферу. В мерзлотно-песчаной почве тундровой экосистемы отмечено высокое разнообразие метаногенных архебактерий, принадлежащих к семействам Methanobacteriaceae, Methanomicrobiaceae, Methanosarcinaceae, Methanosaetaceae в то время, как в криоземе лиственничника регистрировались представители только одного семейства Methanosarcinacea. Метанотрофные сообщества почвы лиственничника представлены двумя типами бактерий (I и II тип) тогда, как в почве тундры найдены лишь представители II типа.
We studied structure, dynamics and functional (biogeochemical) activity of microbial complexes of cryogenic soils in larch forests in Central Evenkia and polygonal tundra on Samoilovskii Island, Lena Delta. We found that daily flux of methane from soil surface is 3-5 times less in forest soil than in the center of polygon in tundra. Short-term heating to 18.5-22.5?°C of permafrost-affected soil in larch forest caused sweetening of soil solution, shrinkage of eco-trophic groups of microorganisms and microbial biomass, as well as increase in greenhouse gases (CO2 and CH4) emission to the air. Notably the permafrost-affected soil on sandy deposits in tundra had highest microbial diversity of methanogenic archaea including Methanobacteriaceae, Methanomicrobiaceae, Methanosarcinaceae, Methanosaetaceae families. On the other hand only Methanosarcinacea were found in cryosols of larch forest. Both type I and type II methanotrophs were found in the forest soil, while only type II methanotrophs occurred in tundra soil.
