Аннотация: Verified estimates of wildfire area and related carbon emissions in territories of Russia are reported for the period of 1998-2010. It is shown that the average burnt area is estimated to be at 8.23 million hectares per year (uncertainty +/- 9.0%, confidence interval 0.9), and carbon emissions-121 Tg C yr(-1) (+/- 23%), with a significant interannual variability of these indicators. A quantitative characteristic of fire emissions by species is reported. Forests are a source of three quarters of all carbon emissions caused by wildfires. A significant acceleration of fire regimes is expected during the 21st century as a result of climate change in the country.

Аннотация: Morphological and cytoembryological studies of unique forms of Siberian pine (Pinus sibirica Du Tour) with the annual cycle of ovulate cone development were carried out. The morphogenesis of female shoots in these anomalous trees with the annual cycle of development was shown to provide for an accelerated development and very rapid growth of megastrobili and accelerated formation of reproductive structures. Cytoembryological studies of ovules in these trees showed significant shortening of the free-nuclear stage of gametophyte development (up to 3 weeks instead of one year) and ultra-early formation of archegonia and egg cells. However, no fertilization of egg cells and the development of embryos occur in the anomalous forms; the egg-cell nucleus divides in the haploid state. Developing seeds are formed without embryo. The author hypothesizes that the acceleration of embryo development in the anomalous pine trees is caused by enhanced hormonal, carbohydrate, and nitrogen metabolism in ovule tissues.

Аннотация: Statistical analysis of high-frequency variations in the radial dimensions of tracheids was carried out using precise measurements of five radial rows in each annual tree ring for several coniferous species: Larix gmelinii, L. leptolepis, L. sibirica, Picea abies, Pinus sylvestris is, P. rigida, and P. densiflora. More than 25 tree rings with a varying number of cells and width were measured for each species. High-frequency variations in radial dimensions were found to have a regular (cyclic) characteristic and accumulated 5 to 11% of the total variability. The cyclic pattern was identified using Fourier analysis of time-related or successive series statistical procedure. The first order autocorrelations (-0.45 to -0.74) and the mean cycle of high-frequency variations (2.1-2.5) did not depend on the number of cells in the annual ring, i.e., they are determined by internal causes. The cyclic pattern of high-frequency variation in tracheid dimensions is used to interpret the seasonal mechanism of xylem formation. Specifically, (1) high-frequency variations in the tracheid radial size take place during the last asymmetrical division of the xylem mother cell before transition to the elongation zone, (2) the final tracheid radial size is mostly determined within the zone of division due to the last asymmetrical division, and (3) acceleration of cell cycle from the initial to the periphery of the cambial zone. The results obtained are also discussed with respect to the mechanisms of xylem differentiation.

Аннотация: The goal of the study was to provide an analysis of climate impact before, during, and after the Little Ice Age (LIA) on the larch (Larix gmelinii) tree line at the northern extreme of Siberian forests. Recent decadal climate change impacts on the tree line, regeneration abundance, and age structure were analyzed. The location of the study area was within the forest-tundra ecotone (elevation range 170-450 m) in the Anabar Plateau, northern Siberia. Field studies were conducted along elevational transects. Tree natality/mortality and radial increment were determined based on dendrochronology analyses. Tree morphology, number of living and subfossil trees, regeneration abundance, and age structure were studied. Locations of pre-LIA, LIA, and post-LIA tree lines and refugia boundaries were established. Long-term climate variables and drought index were included in the analysis. It was found that tree mortality from the 16th century through the beginning of the 19th century caused a downward tree line recession. Sparse larch stands experienced deforestation, transforming into tundra with isolated relict trees. The maximum tree mortality and radial growth decrease were observed to have occurred at the beginning of 18th century. Now larch, at its northern boundary in Siberia, is migrating into tundra areas. Upward tree migration was induced by warming in the middle of the 19th century. Refugia played an important role in repopulation of the forest-tundra ecotone by providing a seed source and shelter for recruitment of larch regeneration. Currently this ecotone is being repopulated mainly by tree cohorts that were established after the 1930s. The last two decades of warming did not result in an acceleration of regeneration recruitment because of increased drought conditions. The regeneration line reached (but did not exceed) the pre-LIA tree line location, although contemporary tree heights and stand densities are comparatively lower than in the pre-LIA period. The mean rate of tree line upward migration has been about 0.35 m yr-1 (with a range of 0.21-0.58), which translates to a tree line response to temperature of about 55 m C-1.

Аннотация: The effect of climate change on the distribution, intensity, and transforming role of wild fires is considered. A general overview of the current wild fire regimes (WRs) and impacts on forest ecosystems and environment is provided. One distinctive feature of WRs is the increasing frequency of disastrous wild fires. The application of various remote sensing instruments has shown that the average vegetation wild fire area in Russia for 1998-2010 accounted for 8.2 +/- 0.8 x 10(6) ha, with about two-thirds of wildfires occurring on forest lands and half on the forested lands. The average annual fire carbon balance during the above period was 121 +/- 28 Tg C yr(-1), including 92 +/- 18 Tg C yr(-1) emitted from the forested land. The forecasts based on the General Circulation Models suggest the dramatic acceleration of fire regimes by the end of the 21st century. Taking into account the increase in the dryness of the climate and the thawing of permafrost, this will likely lead to a dramatic loss of forested area and the impoverishment of the forest cover over a major part of the forest zone. A transition to adaptive forestry would allow a substantial decrease of the expected losses. This paper takes a brief look at the general principals of adapting forest fire protection system to climate change, which is considered an integral part of the transition to sustainable forest management in Russia.

Аннотация: The study of the formation of embryonic structures in Pinus sibirica forms with a one-year reproductive cycle showed that the acceleration of the embryonic process manifested itself as a reduction of the coenocytic stage of the female gametophyte development (1.5 months instead of 1 year). The egg was not fertilized because of the asynchronous maturation of male and female gametophytes. Seeds without embryos were formed. We assumed that the acceleration of the reproductive process in Pinus sibirica was caused by a mutation in the female generative organs. © 2016, Pleiades Publishing, Inc.

Аннотация: We aimed at identifying the microbial response and associated release of CO2 and CH4 in/from thawing soil that has been permanently frozen. For that we performed an in situ field-based incubation experiment in a rim of ice-wedge polygon on Samoylov island, Lena Delta, Russia (72°22’N, 126°28’E). Frozen "buried' organic matter were taken from eroded Lena river bank and transferred to the soil surface in a rim of ice-wedge polygon. The principle includes that formerly frozen soil is moved to the active layer, but still residing in the subsoil in order to mimic cryoturbation processes. The mean seasonal methane efflux from soil surface with the transplaced permafrost soil, as measured in the vegetation period after experiment set up, was 0.55±0.07 mg CH4 m-2 h-1; whereas the mean seasonal methane efflux from plots without buried organic material (i.e., disturbance control) was 0.50±0.02 mg CH4 m-2 h-1. Hence, differences were minor. CO2 emission measured by dark chambers did not differ in magnitude during 4 weeks from the beginning of the vegetation period, and then was approximately 1.5 times larger in plots containing organic material. The release of CO2 from soil was mainly responding to soil temperature, as the Pearson's coefficient for correlation between heterotrophic respiration rate and soil and air temperature was r=0.63, r=0.38, respectively. We conclude that the heterotrophic part of microbial community needs some period for adaptation to the chemical properties of the introduced organic matter (approximately 3-4 weeks). Consequently, due to the short vegetation period in this ecosystem we expect that the acceleration of carbon release is possibly not pronounced. © SGEM2017. All Rights Reserved.

Аннотация: The results of a study of the wood-destroying properties of Siberian strains of xylotrophic basidiomycetes (Armillaria, Ganoderma, Fomitopsis, Heterobasidion and Porodaedalea) are presented. The growth parameters and enzymatic activity of the strains were determined during solid-phase and deep cultivation. Fomitopsis pinicola and Ganoderma lucidum are fast-growing fungi on cellulose-, tannin-containing nutrient media, coniferous and deciduous plant substrates (source and hydrodynamically activated). The growth coefficient on media with tannin and Na-carboxymethyl cellulose is more than 45; on plant substrates - more than 30. The strains exhibit a different growth reaction to the preliminary activation of birch sawdust (growth acceleration / growth slowdown / indifference). The maximum wood-destroying activity on wood of A. sibirica noted for the fungi A. borealis, G. tsugae, G. lucidum, F. pinicola, and P. niemelaei. The decrease in substrate mass was 8-11%; the amount of polysaccharides decreased on average 1.4 times mainly due to the fermentolysis of hard-hydrolyzable polysaccharides. High enzymatic activity of fungi observed during solid-phase and deep cultivation with an inducer. The maximum activity of phenol oxidase is characteristic of G. tsugae (1.21 units/g·s); carboxymethyl cellulase - for F.pinicola and G. lucidum strains (11.8 and 10.3 units/ml, respectively); xylanases - for H. abietinum (3.8 u/ml). The maximum accumulation of extracellular protein observed in F. pinicola (0.89 mg/ml). According to the totality of rapid test indicators, quantitative determination of enzymatic activity, growth parameters on lignocellulosic substrates and the degree of wood bioconversion, the most promising producer of lignolytic enzymes in vitro is the Gl4-16A Ganoderma lucidum strain; cellulolytic enzymes - strain Fp6-17 Fomitopsis pinicola. © 2020 Altai State University.

Аннотация: Изучали мезотрофное болото, осушенное 25 лет назад (географические координаты 56°23′710″ N, 84°34′043″ E). В торфяных почвах (Histosols) средневзвешенная за сезон активность пероксидазы (базовый уровень) составила в режиме слабой гидромелиорации 14.4, умеренной – 21.9, интенсивной – 70 ед. (мл йода на 1 г сух. навески за 2 мин). Основная закономерность развития сезонных колебаний активности пероксидазы описывается полиномом второго порядка. Значения и знаки параметров параболического тренда показывают, что средняя активность пероксидазы еженедельно снижалась на 4.4, 7.6 и 15.2 ед. с еженедельным средним ускорением на 0.31, 0.59 и 1.54 ед. с июня по октябрь в режиме слабого, умеренного и интенсивного осушения соответственно. Сезонные колебания активности пероксидазы относительно базового уровня характеризуется июньским увеличением прироста, максимальным в слое 0–10 см. В июле наблюдается снижение темпов прироста: в режиме слабого и умеренного осушения процесс охватывает весь почвенный профиль в августе, в условиях глубокого осушения – в октябре. Активность фермента достоверно положительно связана с объемной влажностью и величиной рН, отрицательно – с окислительно-восстановительным потенциалом и разнонаправлено – с температурой почв. При оценке вклада условий почвенной среды в сезонную динамику пероксидазы создается эффект взаимозаменяемости экологических градиентов. Методом канонического анализа установлено, что индексы детерминации объясняют совокупное воздействие обсуждаемого множества на 52–74%, главным фактором, регулирующим сезонную активность пероксидазы, является гидротермический режим: в условиях слабого осушения в большей мере под воздействием температуры, интенсивного – влажности, умеренного осушения – влажности и температуры. Активность пероксидазы и глубина гумификации торфяных почв разной степени осушения взаимосвязаны на 87%.
We studied a mesotrophic swamp drained 25 years ago, in the northern part of the Ob and Tom rivers (geographical coordinates 56°23′710″ N, 84°34′043″ E). In forest peat soils (0–30 cm), the weighted average of peroxidase activity for the season (base level) was in the mode of weak hydro reclamation 14.4, moderate – 21.9, intensive 70 units (ml I/g of abs. dry sample in 2 min). Second-order parabola is a most adequate function of the main trend of the development of seasonal fluctuations in peroxidase activity. Numerical values and signs of the parabolic trend parameters show that from June to October, the average peroxidase activity decreased weekly by 4.4, 7.6 and 15.2 units with weekly average acceleration by 0.31, 0.59 and 1.54 units in the mode of weak, moderate and intensive drainage, respectively. The seasonal wave of peroxidase activity relative to the baseline level is characterized by a June increase in growth rates, the maximum in the 0–10 cm layer. In July, there is a decrease in the growth rate according to the depth of reclamation: in the mode of weak and moderate drainage the process already covers the entire soil profile in August, in conditions of intensive drainage – in October. The enzyme activity is significantly positively related with soil bulk moisture and pH, negatively – with redox potential and multidirectionally – with soil temperature. Environmental conditions act as duplicate parameters when assessing their contribution to the seasonal dynamics of peroxidase, creating the effect of interchangeability of environmental gradients. Canonical determination indices approximate the cumulative impact of the discussed set by 52–74%, depending on the depth of reclamation. Canonical weights show that the main factor regulating the seasonal activity of peroxidase is the hydrothermal regime. According to canonical correlations, in conditions of weak drainage, to a greater extent under the influence of temperature, intensive – humidity, moderate drainage – humidity and temperature. The differentiated contribution of peroxidase activity in the formation of the humus state of peat soils of different degrees of drainage was revealed
