Аннотация: Изучено распределение численности слоевищ лишайников различных экологических групп по их отношению к рН коры на 1-24-летних побегах пихты сибирской в горах Южной Сибири. Показано, что доля слоевищ нитрофильных видов статистически значимо положительно коррелирует с величиной pH верхнего запыленного слоя коры ветвей и выше в Восточном Саяне (при средних значениях pH 5.4) по сравнению с Западным Саяном (рН 4.7). Выявленные закономерности позволяют проводить индикацию загрязнения и мониторинг экологического состояния лесных экосистем.

Аннотация: To evaluate the effects of forest fire and post-fire stand recovery on the organic layer chemistry and solute release within mound and trough microrelief elements (termed earth hummock microtopography) that mainly distribute permafrost affected area, we chose five fire plots (larch forests burned in 1951, 1981, 1990, 1994 and 2005) paired with adjacent control plots in mature larch forests in Central Siberian permafrost terrain. We determined total carbon, nitrogen and ash content in solid organic soils, and analyzed total carbon, nitrogen, bases and major anions in water extracts. There was a significant correlation between water-extracted organic carbon (WEOC) and total carbon (kg m(-2)) in area basis, implying that the quantity of total carbon was a major factor in WEOC production. WEOC correlated negatively with pH, indicating strong control by organic horizons (organic solute leaching) on soil acidity and base cation dynamics. The sum of water extractable base cations was also correlated significantly to total carbon, indicating that cations can be released through organic matter decomposition. Organic horizons in troughs in burned plots released greater amounts of Ca, Mg and K than those in mounds, probably due to greater content of organic matter as a cation source. Anions including nitrate and phosphate and WEOC also accumulated in trough depressions, due probably to organic matter degradation. The contrasting distribution of solutes between mounds and troughs in burned plots seems to be controlled by organic horizon development via changes in microtopography after forest fires.

Аннотация: Changes in the composition of microbial complexes and their biochemical activity in soil in the vicinity of a strong source of HF emission have been studied. A sharp decrease of the biomass, the number of asporous bacteria and actinomycetes, and a smaller decrease of the number of microscopic fungi has been revealed, along with a decrease in the enzymatic and respiratory activity of contaminated soil with the relative increase in the fraction of sporiferous bacteria. On the basis of the response of introduced population of Bacillus subtilis to different doses of HF, NaF, Na(2)SO(3) microbiological norm-fixing for technogenic soil ecosystems has been carried out.

Аннотация: Vertical and horizontal distributions of soil organic carbon, potential microbial activity and basic soil properties were studied in a boreal mixed forest (Central Forest Reserve, TVER region) to elucidate whether the soil CO(2)-efflux is related to basic soil properties that affect the C pool and activity. Soil cores (0-100 cm depth) were taken from two transects every 50 meters (44 points) immediately after completion of soil CO(2)-efflux measurements. Soil was separated into layers and moisture, bulk density, root density and bacterial counts were determined within one day after soil was taken. Microbial respiration, biomass, CN contents and pH were measured within few months. The variability in the soil CO(2)-efflux and microbial activity was mainly explained by soil bulk density. Results further indicate that laboratory measurements of microbial respiration can represent heterotrophic soil respiration of a distinctive ecosystem in natural conditions, if microbial respiration is measured after the effect of soil handling disappears.

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: Soil microbial properties were studied from localities on a transect along the Yenisei River, Central Siberia. The 1000 km-long transect, from 56degreesN to 68degreesN, passed through tundra, taiga and pine forest characteristic of Northern Russia. Soil microbial properties were characterized by dehydrogenase activity, microbial biomass, composition of microbial community (PLFAs), respiration rates, denitrification and N mineralization rates. Relationships between vegetation, latitude, soil quality (pH, texture), soil organic carbon (SOC) and the microbial properties were examined using multivariate analysis. In addition, the temperature responses of microbial growth (net growth rate) and activity (soil respiration rate) were tested by laboratory experiments. The major conclusions of the study are as follows: 1. Multivariate analysis of the data revealed significant differences in microbial activity. SOC clay content was positively related to clay content. Soil texture and SOC exhibited the dominant effect on soil microbial parameters, while the vegetation and climatic effects (expressed as a function of latitude) were weaker but still significant. The effect of vegetation cover is linked to SOC quality, which can control soil microbial activity. 2. When compared to fine-textured soils, coarse-textured soils have (i) proportionally more SOC bound in microbial biomass, which might result in higher susceptibility of SOC transformation to fluctuation of environmental factors, and (ii) low mineralization potential, but with a substantial part of the consumed C being transformed to microbial products. 3. The soil microbial community from the northernmost study region located within the permafrost zone appears to be adapted to cold conditions. As a result, microbial net growth rate became negative when temperature rose above 5 degreesC and C mineralization then exceeded C accumulation.

Аннотация: Natural colonization of the steppe by forest vegetation is often observed in the contact zone between forest and steppe communities in northern Mongolia. Such successions appear owing to cyclic changes in the climate humidity. It was shown that morphological features of noncalcareous chernozems and their dynamic properties (pH, total exchangeable cations, humus composition) change under the influence of forest vegetation. These changes, however, are insufficient for attributing such chernozems to a new category.

Аннотация: The structure and functions of the microbial complexes in the soils after surface fires of different intensity were studied. The fires of high and medium intensity were found to lead to a significant decrease in the number and functional activity of microorganisms participating in the nitrogen-carbon cycle. The degree of changes in the postfire status of the soil microbocenoses was revealed to be related to the joint action of pyrogenesis and the hydrothermal conditions at the moment of the fire rather than to the fire intensity. The favorable combination of the elevated soil moisture and soil heating stimulates the microbiological processes of organic matter mineralization, thus, improving the forest-growing conditions for the pine forests. The microbial biomass, basal respiration, and the microbial metabolic coefficient are shown to adequately reflect the postfire status of the microbial complexes.

Аннотация: The application of multiparametric statistical methods has confirmed that peat soils are different in the degree of their drainage and properties because of their modification during a 20 - 25 year period of artificial drainage operation. The following sequence represents the relative significance of the contribution to the soil changes of the parameters studied: groundwater table air capacity pH T-0 Eh water-soluble: C Fe3+ and the activity of soil oxidoreductases in the following sequence: peroxidase catalase dehydrogenase. The necessity to supplement the substantive - genetic principle of the classification of drained peat soils with characterization of their water regime is substantiated.

Аннотация: The state of microbial cenoses in the soils of forest ecosystems damaged by fires of different strengths and gypsy moth outbreaks (Central Siberia) was assessed by the intensity of the basal respiration, the content of carbon of the microbial biomass, and the microbial metabolic quotient. The degree of the disturbance of the microbial cenoses in the soils under pine forests after fires was higher than that in the soils under the forests defoliated by gypsy moths. The greatest changes of the microbial complexes were recorded after the fires of high and medium intensity. In the litters, the content of the microbial biomass, the intensity of basal respiration, and the microbial metabolic quotient value were restored on the fifth year after the fires, whereas in the upper (0-10 cm) soil layer, these parameters still differed from those in the control variant, especially after the highly intense fires. After the weak fires, the ecophysiological state of the microbial complexes was restored within two-three years.

Аннотация: Natural and human-induced changes in the composition of boreal forests will likely alter soil properties, but predicting these effects requires a better understanding of how individual forest species alter soils. We show that 30 years of experimental afforestation in Siberia caused species-specific changes in soil chemical properties, including pH, DOC, DON, Na+,NH4+, total C, C/N, Mn2+, and SO42-. Some of these properties-pH, total C, C/N, DOC, DON, Na+-also differed by soil depth, but we found no strong evidence for species-dependent effects on vertical differentiation of soil properties (i.e., no species x depth interaction). A number of soil properties-NO3-, N, Al3+, Ca2+, Fe3+, K+, Mg2+ and Cl- -responded to neither species nor depth. The six studied species may be clustered into three groups based on their effects on the soil properties. Scots pine and spruce had the lowest pH, highest C/N ratio and intermediate C content in soil. The other two coniferous species, Arolla pine and larch, had the highest soil C contents, highest pH values, and intermediate C/N ratios. Finally, the two deciduous hardwood species, aspen and birch, had the lowest C/N ratio, intermediate pH values, and lowest C content. These tree-mediated soil chemical changes are important for their likely effects on soil microbiological activities, including C and N mineralization and the production and consumption of greenhouse gases.

Аннотация: Effect of tannin and non-volatile components of lesion resin on the growth of blue-stain fungi - Ceratocystis laricicola, C. polonica, Ophiostoma minus, Leptographium sp. and Ophiostoma sp. - the primary invaders of conifers in Siberia (Russia), has been studied. The fungi under study exhibited tolerance to plant's defensive substances in bioassays. The cultures of Leptographium sp., C. polonica, and Ophiostoma sp. proved to be the most tolerant to tannin. In the range between 0.05 and 0.15% tannin concentration their growth tended to stabilize. Less tolerant to tannin were C. laricicola and O. minus. With an increase in tannin concentration their biomass gradually decreased. The fungi more tolerant to tannin regulated the medium pH about 5.0 and higher, white the species which were less tolerant preferred lower pH values. Lesion resins of conifers differed in their inhibitory effect on fungal growth. Fir resin had the greatest inhibitory effect of all the conifer resins tested, causing reduction to 50-60% in fungal growth. When fungi were grown on the resin of any other conifer, the reduction in the linear growth rate did not exceed 20 to 30%. The assumption that fungi are more tolerant to the resin of a host plant than to that of a non-host plant has not been confirmed.

Аннотация: Quinate:NAP(P)(+)-oxidoreductase (QORase, EC 1.1.1.24), which catalyzes the interconversion of quinic and 3-dehydroquinic acids, was purified from the needles and developing xylem cells of Larix sibirica. The enzymes from these two tissues were partially characterized and compared. QORase from needles had optimum pH at 9.0 and apparent K-m values of 1.84 mM for quinic acid and 0.19 mM for NADP(+). The enzyme was activated by phosphoenolpyruvate. Gallic and protocatechuic acids were formed in a reaction mixture of purified enzyme from needles as final products of quinic acid transformation. QORase from developing xylem cells showed pH optimum at 10.0 and had apparent K-m values of 0.70 mM for quinic acid and 0.05 mM for NADP(+). The enzyme was not affected by PEP. The divalent cations Co2+ and Mn2+ at least doubled activity of QORase from both sources but Mg2+ affected the enzyme from needles only. The spatial organization and regulation of quinic acid metabolism in the autotrophic and heterotrophic cells of conifers and the role of QORase in this process are discussed.

Аннотация: Обнаружено 40 видов эпифитных лишайников, произрастающих на березе и тополе в зеленых насаждениях г. Красноярска. Установлена тенденция изменения видового состава и покрытия лишайников в зависимости от кислотности коры березы и тополя, которая изменяется от кислых в сторону нейтральных и даже слабощелочных значений рН в зависимости от произрастания деревьев в различных районах города. Показано, что лишайники произрастающие на березе можно использовать для обнаружения на обследуемой территории как кислых, так и щелочных загрязнителей. На кислом субстрате доминируют многие виды лишайников (например, Flavopunctelia soredica, Opegrapha rufescens и др.). Индикаторами защелачивания субстрата являются Caloplaca haematites, Lecanora hagenii, Candelariella aurella, Candelaria concolor и др. Выявлены виды, произрастающие в широком диапазоне кислотности субстрата (Physcia aipolia, Ph. dubia, Ph. adscendens, Ph. caesia, Candelariella vitellina).

Аннотация: Хинат-дегидрогеназа выделена из молодой хвои лиственницы сибирской и частично очищена в фракционированием сульфатом аммония. Показано, что у хвойных, в отличие от других растений, хинат-дегидрогенеза проявляет активность как с NAD, так и с NADP. Величины K(m) для хината и NADP равны соответственно 1,8 и 0,18 мМ. Фермент максимально активен при pH 9.0. Предполагается, что NADP-зависимая хинат-дегидрогеназа ответственна за синтез хинной кислоты. Обсуждаются особенности организации и регуляции начальных этапов шикиматного пути у хвойных.

Аннотация: Шикиматдегидрогеназа выделена экстракцией их хвои сосны обыкновенной и частично очищена фракционированием сульфатом аммония. У хвойных, в отличие от других растений, все три изофермента шикиматдегидрогеназы проявляют активность не только с NADP+, но и с NAD+. Значения K(m) для шикимата при использовании в качестве кофакторов NADP+, но и с NAD+ соответственно 0,22 и 1,13 мМ. Фермент максимально активен при pH 10 с обоими кофакторами. Высказано предположение, что альтернативного пути превращения шикимовой кислоты в оксибензойные кислоты. Обсуждаются особенности организации и регуляции начальных реакций шикиматного пути у хвойных и у растений с шикиматдегидрогеназой, абсолютно специфичной к NADP.
