Аннотация: The major parameters of the carbon cycle were studied in the pine stands of green moss and lichen proups of forest type using biometric method. The study was carried out for stands age sequence (15-260 years old) in the Zotinskii experimental polygon of Yenisei Transect. Heterotrophic respiration changes a little with age of the pine stands, therefore, net ecosystem production of these stands, in generally, mainly determines by age changes in the net primary production intensity.

Аннотация: The microbial community's structure in cryogenic soils of post-fired areas of Central Evenkia was examined. It was shown that microbial biomass and heterotrophic respiration rates in cryogenic soils of post-firee areas recovered for mineral layer of lichen and moss synusia after 14 and 18 yaers accordingly. Microbial biomass and heterotrophic respiration rates in the litter of post-fire areas remain disturbed. The eco-physiological status of microbial communities in cryogenic soils of post-fired areas in litter and mineral layer of moss synusia recovered after 18 years. On the contrary eco-physiological status of microbial communities in mineral layer of lichen synusia remain disturbed. The investigated time period is not enough for recovering of microbial communities structure.

Аннотация: This paper studies the structure and dynamics of the major pools of organic matter in clearings in the lichen pine forests of the middle taiga subzone of Yenisei Siberia, in the range of measurements of the international observatory Zotto, a high-tech research platform for long-term ( 30 years) monitoring of the atmosphere and climate changes. The contribution of phytocenoses at different stages of post-clearing succession in the process of deposition of atmospheric carbon is analyzed. In conjunction with the data on atmospheric measurements of a wide range of greenhouse gases carried out at the base of the observatory, the results of this work will be used for modeling the stocks and flows of carbon in forest ecosystems of Central Siberia.

Аннотация: The symbiotic fixation of atmospheric nitrogen by leguminous plants in the alpine community of a lichen heath at the Teberda State Biosphere Reserve is well adapted to low soil temperature characteristic for the altitude of 2800 m a.s.l. For the determination of the N fixation by isotopic methods (the method of the natural (15)N abundance and the method of isotopic (15)N dilution), Trifolium polyphyllum was taken as the control plant. This plant was used as it does not form symbiosis with the nitrogen-fixing bacteria in the highlands of the Northern Caucasus Region. The contribution of the N fixation to the N nutrition of different leguminous plant species as determined by the natural (15)N abundance method amounted to 28-73% at delta(15)N(0) = 0aEuro degrees and 46-117% at delta(15)N(0) = -1aEuro degrees; for the determination of the N fixation by the method of the isotopic label's dilution, it was 34-97%. The best correlation of the results obtained by these two isotopic methods was observed for the natural fractionation of the N isotopes in the course of the N fixation in the range of -0.5 to -0.7aEuro degrees. The determination of the nitrogenase activity of the roots by the acetylene method confirmed the absence of N fixation in T. polyphyllum and its different contribution to the N nutrition of different species of leguminous plants.

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.

Аннотация: The abundance distribution of different ecological groups of lichens depending on bark pH has been studied on 1- to 24-year shoots of Siberian fir in the mountains of southern Siberia. Along with acidophytic lichens commonly found on the Siberian fir (Usnea sp., Bryoria sp., etc.), its young shoots are also colonized by nitrophytic species (Physcia tenella, Melanelia exasperatula, etc.), which is evidence for the increasing pH of shoot bark. The proportion of thalli of nitrophytic lichen species shows a significant positive correlation with the pH of the upper (dusted) bark layer and is greater in the Eastern Sayan (at bark pH averaging 5.4) than in the Western Sayan (pH 4.7). The trends revealed in this study may be used for indication of pollution and ecological monitoring of forest ecosystems.

Аннотация: The distribution of different ecological groups of lichens (acidophytes, 'nitrophytes', indifferent species) was compared on 1-24 year-old twigs of Abies sibirica sampled in the 'pristine' West Sayan and the polluted East Sayan Mountains (Krasnoyarsk District, South Siberia, Russia) to test their value as indicators of current pollution effects. Bark pH of twigs and bark chemistry (N, S, Ca, Mg, Al, Fe) were measured, and a preliminary estimate of emissions in the Krasnoyarsk District from livestock animal populations was calculated. In both regions, an unusually high twig bark pH and an abnormal species composition for A. sibirica canopy were found (e.g. Physcia aipolia, P. dubia, P. tenella, Phaeophyscia sp., Melanelia exasperatula and Candelariella vitellina), with P. tenella (East Sayan) and M. exasperatula (West Sayan) as dominants. The results confirm that the distribution of lichen species on Abies sibirica twigs is a valuable indicator of current changes in atmospheric conditions.

Аннотация: Thallus morphology and element concentrations (S, Al, Fe, Sr, Mn, Ni, Zn, Cu, Pb, As, F, and Cl) were compared in samples of the fruticose lichen genus Usnea at two heights of the Abies sibirica canopy in the East Sayan Mountains (Krasnoyarsk District, Russia) sampled from three stations at 15, 25 and 35 km from Krasnoyark. Usnea species with an abnormal morphology dominated on branches in the upper canopy, 15-22 m above ground level, and normal thalli on lower tree branches, 2-5 m above ground. Abnormal thalli at the tree-top level contained higher Al, Fe, Zn, F, Sr and Pb concentrations compared with normal thalli growing below, confirming a dust impact. No such clear trend was observed between sampling stations. Crown canopy architecture, surface microtopography and the balance between the processes of deposition and the movement and loss of particles play a major role in particle interception and in pollutant delivery to Usnea.

Аннотация: At present, the thawing depth in permafrost-affected soils is measured from the surface of the moss-lichen cover; if the latter is absent, measurements are performed from the surface of the litter layer. In the first case, the thickness of the root zone is less than the thawing depth by the thickness of the moss-lichen layer; in the second case, the thickness of the root zone is virtually equal to the thawing depth. Thus, upon equal thawing depths, the soil temperature regime in the root zone under the moss-lichen cover differs from that in the soil without this cover. In order to avoid this discrepancy, it is suggested that the thawing depth should be measured from the upper boundary of the root zone.

Аннотация: The evaluation of biospheric role of the boreal forests in the accumulation of carbon is connected with the evaluation of organic matter (OM) pool in soils. The research sites were larch forests, they are situated on Nizhne-Tungusskoe Plateau. Larch forests of feather-moss and lichen types (110 and 380 years old) were formed on 'ochric podbur' soils. Litter stocks are 3.5-4.5 kg m-2 with thickness 10-25 cm. Cryomezomorphic northern taiga soils contains 38-73 t (carbon) ha-1. Pool of fast mineralized OM has average value 38.1 t (carbon) ha-1, including 20.5 and 6.4 t (Carbon) ha-1 of labile compounds on surface and in the soil, and 11.2 t (carbon) ha-1 of mobile OM. Microbial mass reaches 1.78-3.47 t (carbon) ha-1, its proportion is 3.6-4.9% of the total OM carbon. Zoomass of feather-moss larch forest is 0.20-0.61 * 10-2, in lichen larch forest -0.01-0.07 * 10-2 t (carbon) ha -1. A pool of resistant to biological decomposition and bonded to mineral soil matrix OM is 17.7 t (carbon) ha-1 and it varies from 18.6 to 29.0 in feather-moss larch forest, and from 6.4 to 17.0 t (carbon) ha-1 in lichen larch forest. Two-years field experiment has been performed to determine transformation rates of various plant litter fractions and to clarify the role of soil biota in these processes. The results showed participation of all biota groups in the decomposition of plant residues caused weight loss of larch-needles and root mortmass. Isolation of organic matter from all-size invertebrate groups leads to some decrease of decomposition activity. В© Springer 2006.

Аннотация: The study was carried out in the Turukhansk Research Station of Yenisei Transect (65В°46'N, 89В°25'E). Larch (Larix gmelinii (Rupr.) Rupr.) is the dominant overstory tree species. The research has been conducted on four permanent test plots in same-age mature (110-year old) and overmature (380-year old) post-fire larch stands of green moss and lichen groups of forest type. Carbon cycle parameters were assessed based on a biometric method. Quantitative analysis of carbon pools and fluxes shows that net ecosystem production of north taiga larch stands averages 32% of net primary production. Sink of atmospheric CO2 makes 1.22 and 0.74 t C ha-1 year-1 for mature and overmature green moss larch stands, and 0.65 and 0.35 t C ha -1 year-1 for lichen type. Net carbon sink in the tree layer make up 9% of net primary production carbon, ground vegetation - 15%, and dead plant residues accumulation - 8% of atmospheric carbon uptake via photosynthesis.

Аннотация: As part of the Russian FIRE BEAR (Fire Effects in the Boreal Eurasia Region) Project, replicated 4-ha experimental fires were conducted on a dry Scotch pine (Pinus sylvestris)/lichen (Cladonia sp.)/feathermoss (Pleurozeum schreberi) forest site in central Siberia. Observations from the initial seven surface fires (2000-2001) ignited under a range of burning conditions quantified the different fuel consumption and fire behavior characteristics (e.g., rate of spread, fireline intensity, etc.) possible in this particular forest fuel type. Experimental results and dendrochronological study of local fire history both support the dominance of local fire regimes by low to moderate-intensity surface fires. Carbon released by the experimental fires ranged from 4.8 to 15.4 t C ha -1 depending on fuel conditions and fire severity. Preliminary emission data show a strong correlation between carbon dioxide (CO 2) and carbon monoxide (CO) emissions, which should facilitate accurate estimates of fire impacts on atmospheric chemistry. Carbon concentration in smoke samples was related to fire severity. The short landscape-scale fire-return interval (50 years), combined with typically low fire severity, in pine ecosystems of central Siberia is often associated with low tree mortality and relatively rapid buildup of litter and understory fuels after a fire.

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.
