Аннотация: Models of climate warming predict the migration of "warm-adapted' species to habitates of "cold-adapted" species. Here we show evidence of expansion of "dark-needle" conifers (DNC: Siberian pine, spruce and fir) into the habitat of larch, the leader in adaptation to harsh climatic conditions in Asia. The studies were made along two transects oriented from the western and southern borders of a larch dominated forest to its center. The invasion of DNC into the historical larch habitat was quantified as an increase of the proportion of those species both in the overstory and in regeneration. The age structure of regeneration showed that regeneration occurred mainly during the last 2-3 decades. In particular warm winter temperatures promote the survival regenerated Siberian pine. The results obtained indicate the climate-driven migration of Siberian pine, spruce and fir into traditional zone of larch dominance. Substitution of a deciduous conifer (larch) by evergreen conifers decreases the albedo and may provide positive feedback for temperature increases.

Аннотация: This is a short review of our recent studies on trophic adaptation of a boreal forest pest, the Siberian moth in its native range, North Asia and in Central Europe where the species is believed to invade in a near future. In Europe, the hierarchy in suitability of host plant genera (increasing from two-needle pines, spruce, fir, to larch) remains similar to that in the pest range. Besides European plants, some North American conifers from genera which do not exist in the pest habitat can be served as potential hosts for the insect.

Аннотация: Results of dendroclimatic analysis for Gmelin's larch stands from three sites located along a short topographic transect in a continuous permafrost zone in the north of Central Siberia are presented. Comparative analysis of tree radial growth rates and year-to-yaer variability, as well as climatic response of master chronologies was carried out in relation to the local habitat conditions. Obtained results indicate that the dynamics and climatic response of radial growth is sufficiently different at the sites located along a short distance. This shows that site conditions (i.e. depth and the rate of permafrost thaw) are of crucial importance for spatial variability of tree growth on permafrost soils even within the neighboring stands.

Аннотация: The spatial pattern of Siberian silkmoth outbreak in south Siberian mountains was analysed based on SPOT VEGETATION data. A digital elevation model (DEM) was also used to relate outbreak area dynamics with topographic elements (elevation, azimuth and slope steepness). To avoid bias of spatial pattern data, areas with a given damage category and with given azimuth, slope steepness and elevation were referenced to the areas with similar parameters within the entire study area. The outbreak began between the elevations of similar to 430-480 m and on south-west slopes with steepness 5 degrees; these conditions appear to be the most favourable pest habitat. As the pest searched for food it moved up and down slope, resulting in an elevation distribution split within a range of similar to 390-540 m and slope steepness up to 15 degrees. In the final phase the azimuth distribution of damaged stands became even, showing that pests at this phase settle in non-optimal habitat. The final outbreak area was similar to 20 000 ha, which is in good agreement with on-ground data. The correlation between the initial phase of infestation and topographic features can be used to prioritize pest monitoring. Data obtained show that the SPOT VEGETATION sensor is applicable for monitoring taiga landscapes vulnerable to Siberian silkmoth outbreaks.

Аннотация: We measured the seasonal dynamics of major and trace elements concentrations in foliage of larch, main conifer species of Siberia, and we analyzed cryogenic soils collected in typical permafrost-dominated habitats in the Central Siberia. This region offers a unique opportunity to study element fractionation between the soil and the plant because of (i) the homogeneous geological substratum, (ii) the monospecific stands (Larix gmelinii) and (iii) the contrasted habitats (North-facing slope, South-facing slope, and Sphagnum peatbog) in terms of soil temperature, moisture, thickness of the active layer, tree biomass and rooting depth. The variation of these parameters from one habitat to the other allowed us to test the effects of these parameters on the element concentration in larch foliage considered with high seasonal resolution. Statistical treatment of data on larch needles collected 4 times in 3 locations during entire growing season (June-September) demonstrated that : (1) there is a high similarity of foliar chemical composition of larch trees in various habitats suggesting intrinsically similar requirements of larch tree growth for nutrients, (2) the variation of elemental concentrations in larch needles is controlled by the period (within the growing season) and not by the geographical location (South-facing slope, North-facing slope or bog zone) and (3) there are three groups of elements according to their patterns of elements concentration in needles over the growing season from June to September can be identified: (1): nutrient elements [P, Cu, Rb, K, B, Na, Zn, Ni and Cd] showing a decrease of concentration from June to September similar to the behaviour of major nutrients such as N, P and K; (2): accumulating elements [Ca, Mg, Mo, Co, Sr, Mn, Pb and Cr] showing an increase of concentration from June-July to September; (3): indifferent elements [Al, Zr, Fe, Ba, Ti, REEs (Pr, Nd, Ce, La, Gd, Er, Dy, Tb, Lu, Yb, Tm, Sm, Ho, Eu), Y, Th and U] showing a decrease of concentration from June to July and then an increase of concentration to September. A number of micronutrients (e.g., Cu, Zn) demonstrate significant resorption at the end of growing season suggesting possible limitation by these elements. Although the intrinsic requirement seems to be similar among habitats, the total amount of element stored within the different habitats is drastically different due to the differences in standing tree biomass. The partitioning coefficients between soil and larch appear to be among the lowest compared to other environments with variable plants, soils and climates. Applying the "space for time" substitution scenario, it follows that under ongoing climate warming there will be an increase of the element stock following enhanced above-ground biomass accumulation, even considering zero modification of element ratios and their relative mobility. In this sense, the habitats like south-facing slopes can serve as resultant of climate warming effect on element cycling in larch ecosystems for the larger territory of Central Siberia.

Аннотация: Mechanical treatment and prescribed fire were used to restore a mixed conifer stand (Picea-Abies-Pinus) following mortality from an outbreak of Siberian moth (Dendrolimus superans sibiricus). Moth-killed stands often become dominated by Calamagrostis, a sod-forming grass. The large amount of woody debris and the sod hinder coniferous seedling establishment and development as well as creating conditions favorable to the establishment and propagation of wildfires. Fire has been demonstrated to be an effective method of reducing woody debris and eliminating sod, but the random nature and timing of wildfires often do not create conditions favorable for conifer regeneration. Our study was conducted in a mature fir dominated stand that died during an outbreak 6-8 years previously with most of the dead trees still standing. A bulldozer drove through the stand downing standing snags in late summer with 15-20 m between passes. Snags knocked down by the bulldozer and additional snag fall throughout the following winter increased downed dead wood 50-60% and large downed dead wood 80% compared to an adjacent untreated area. In June, a prescribed fire was set and fuel load consumption averaged 70%. Average soil temperatures during the burn ranged from 47В°C at a depth of 2 cm to 10В°C at 10 cm; hot enough to kill the grass. Following treatment, the potential for wildfire was reduced and the area was suitable for either natural conifer regeneration or planting without further mechanical site preparation.

Аннотация: A game theory model of insect population dynamics is proposed. In the simplest case-when a population can be in one of two states, in one of which the physiological processes in an individual are aimed at enhancing the growth and reproduction, and in the other the physiological processes are aimed at activating defense reactions of an individual-outbreaks of insect propagation occur when both the population and the habitat have a certain kind of memory, specifically, when the current states of the population and the habitat depend on their states at the preceding moment of time. The model proposed explains the well-known phenomenon of phase variation among insect individuals during the population outbreak. Copyright В© 2003 by MAIK "Nauka/ Interperiodica".

Аннотация: Investigations on B chromosomes found for the first time for Picea abies (L.) H. Karst. have been conducted. Seeds of Picea abies from two populations of Western Rhodopes (Bulgaria) located at the southern border of species range, and protected according to Bern Convention and EC Habitat Directive were collected for this study. Mixoploidy was detected in some germinating seeds of Picea abies. It was found that metaphase cells of germinating seeds contain 0-4 B chromosomes of both metacentric and submetacentric types. The variability of B chromosomes number and their occurrence was observed. Along with B chromosomes, some chromosome aberrations such as fragments and ring chromosomes were revealed in metaphase cells of Picea abies from studied populations. The possible adaptive role of B chromosomes presence for Picea spp. is discussed.

Аннотация: Birch (Betula pendula Roth) growth within the Western Siberia forest-steppe was analyzed based on long-term (1897-2006) inventory data (height, diameter at breast height [dbh], and stand volume). Analysis of biometry parameters showed increased growth at the beginning of twenty-first century compared to similar stands (stands age = 40-60 years) at the end of nineteenth century. Mean height, dbh, and stem volume increased from 14 to 20 m, from 16 to 22 cm, and from ?63 to ?220 m3/ha, respectively. Significant correlations were found between the stands mean height, dbh, and volume on the one hand, and vegetation period length (rs = 0.71 to 0.74), atmospheric CO2 concentration (rs = 0.71 to 0.76), and drought index (Standardized Precipitation-Evapotranspiration Index, rs = -0.33 to -0.51) on the other hand. The results obtained have revealed apparent climate-induced impacts (e.g. increase of vegetation period length and birch habitat drying due to drought increase) on the stands growth. Along with this, a high correlation of birch biometric parameters and [CO2] in ambient air indicated an effect of CO2 fertilization. Meanwhile, further drought increase may switch birch stand growth into decline and greater mortality as has already been observed within the Trans-Baikal forest-steppe ecotone. © 2014 © 2014 Taylor & Francis.

Аннотация: Since information on the distribution of the white-toothed shrew in Central Siberia is scarce, the objective of the present work was to present new data on their distribution and habitat restrictions. The data on 10 new records of the white-toothed shrew group Crocidura suaveolens Pallas 1811 - Crocidura sibirica Dukelsky 1930 in Central Siberia are presented. Most of the records stem from the right bank of Yenisei River, where almost no information on their distribution was available. Genetic and morphological analyses confirmed the identity of all records to the Siberian white-toothed shrew. Based on this, with a high degree of confidence one can say that the distribution of the white-toothed shrew is not confined to the left bank of the Yenisei River alone, but it also covers the northern slopes of the Eastern Sayan Mountains and the Yenisei Ridge. In contrast to the small shrews associated with desert and steppe habitats, the white-toothed shrew in the Minusinskaya Siberian Basin and on the right bank of the Yenisei is confined to subtaiga habitats (light coniferous small-leaved forests with herbs). The animals are distributed sporadically, with extremely low numbers and are captured but individually.

Аннотация: Global warming is most pronounced in high-latitude regions by altering habitat conditions and affecting permafrost degradation, which may significantly influence tree productivity and vegetation changes. In this study, by applying a "space-for-time" approach, we selected three plots of Larix gmelinii forest from a continuous permafrost zone in Siberia with different thermo-hydrological soil regimes and ground cover vegetation with the objective of assessing how tree growth and productivity will change under different stages of permafrost degradation. A tree-ring multi-proxy characterization of mature trees was used to identify shift in ecophysiological responses related to the modified plant-soil system. Variability of tree-ring width (1975-2009), stable isotope ratios (oxygen and carbon, 2000-2009) and xylem structural characteristics (2000-2009) under climatic conditions of particular years indicated that an increased depth of the soil active layer will initially lead to increase of tree productivity. However, due to an expected water use increase through transpiration, the system might progressively shift from a temperature to a moisture-limited environment. (C) 2015 Elsevier GmbH.

Аннотация: The boreal forest accounts for approximately 22% of the Northern Hemisphere landmass with nearly 40% of this huge biome growing on continuously frozen soils. Projected climate change leading to degradation of permafrost and increasing drought situation at high latitudes in Eurasia will seriously affect productivity of forests on permafrost. Here we present the results of an on-going research of tree radial growth in the midst of the permafrost zone in Siberia, Russia (Tura region, 64 degrees N, 100 degrees E, 140-610 m a.s.1.). Tree-ring width and density chronologies of Gmelin larch and Siberian spruce from a great variety of sites characterized by different thermo-hydrological regime of soils are analyzed. The obtained results reveal that current tree radial growth and tree-ring structure in permafrost region in Siberia are largely dependent on local site conditions and may be constrained by low air and soil temperatures as well as soil water availability. Varying climatic responses and seasonal radial growth of trees at different habitats indicate a range of possible scenarios of further development of northern larch stands. Forest fire is another important factor strongly affecting tree stand dynamics and forest ecosystem functioning in the continuous permafrost zone. Analysis of tree-ring parameters indicate that post-fire dynamics of tree-ring structure is in accordance with the changes in habitat conditions caused by removal by fire and then gradual recovery of ground vegetation resulting in an alteration in soil active layer depth. In general, the results of this multi-proxy analysis for trees growing under various conditions in the continuous permafrost zone in Siberia allow assumptions about changes in tree productivity, stand dynamics and therefore carbon uptake under projected climate change and permafrost degradation.

Исследования проводили на двух пробных площадях: непосредственно на границе с тундрой (303 м над ур. м.) и на расстоянии 1700 м от границы, в глубине древостоя (71 м над ур. м.). У 10 деревьев, имеющих примерно одинаковые диаметр на высоте груди и высоту, измерены ширина годичных колец, образованных с 1964 по 2009 г., в каждом кольце - количество и радиальные размеры ранних и поздних трахеид и толщина их стенок, радиальные размеры ранней и поздней древесины; рассчитаны размеры люменов трахеид. Выявлено, что «пограничные» деревья лиственницы, произрастающие непосредственно на границе с тундрой, отличаются от деревьев в глубине древостоя более широкими годичными кольцами, их кольца содержат меньшую долю поздней древесины и большее количество ранних трахеид со сравнительно крупными люменами. С помощью коэффициентов чувствительности, представленных в виде контурных диаграмм, показано, что анатомическое строение годичных колец у «пограничных» деревьев характеризуется большей чувствительностью к изменению условий внешней среды, причем строение поздней зоны отличается особенно высокой чувствительностью. Установлено, что у «пограничных» деревьев в отличие от деревьев в глубине древостоя изменчивость анатомических показателей древесины, связанная с вариабельностью климатических факторов, превышает индивидуальную изменчивость, связанную, главным образом, с неодинаковыми локальными условиями роста каждого дерева и генетически обусловленными различиями между деревьями. Показано, что ширина годичных колец, ширина ранней и поздней древесины в годичных кольцах, а также количество трахеид в зонах отличаются от остальных показателей высокой чувствительностью, а толщина клеточных стенок и радиальный размер люменов - низкой, поэтому не могут служить надежными индикаторами изменения внешних факторов.
The study of tree-ring cell structure changes as the result of tree adaptation to varying environmental conditions becomes increasingly important to predict future vegetation shifts under projected climate changes. The estimate of intrapopulation annual variability of wood anatomy characteristics is particularly informative. It helps to divide the contribution of different ecological factors to total features dispersion. In this work, a comparative analysis of individual and climatic variability of tree ring structure characteristics of Gmelin's larch Larix gmelinii (Rupr.) growth within northernmost forest was carried out. The trees from forest-tundra boundary has greater radial growth intensity, forms the bigger conductive zone in rings with wider mean lumen area in comparison with trees from closed forest. This result can be explained by adaptive features and height ecological xylem plasticity of larch. The tree rings structure of larch from boundary with tundra is determined by largely current weather conditions. Is because these ones evince high adaptive plasticity on the level of xylem structure. The xylem reflects joint changes of climate factors and local ecological conditions. The trees from closed forest are characterized by larger individual variability. The local conditions in oldest forest (for example, bad hydrothermal soil conditions) inhibit the radial growth and sensitivity to environmental factors. In this case, the trees on individual level are tended to save the normal functioning of water-transport system. The significant differences in ratio individual to climate variability of tree ring structure characteristics can be caused by the different in the level of ecological habitat heterogeneity or the different in the level genetic within-population heterogeneity.

Аннотация: Reliable niche models are a cornerstone of pest risk analyses, informing biosecurity policies and the management of biological invasions. Because species can invade and establish in areas with climates that are different from those that are found in their native range, it is important to accurately capture the range-limiting mechanisms in models that project climate suitability. We examined a published niche model for the beet armyworm, Spodoptera exigua, to assess its suitability for bioeconomic analyses of its pest threat, and identified issues with the model that rendered it unreliable for this purpose. Consequently, we refitted the CLIMEX model, paying close attention to the biology underpinning the stress mechanisms. This highlighted the necessity of carefully considering how the different stress mechanisms operate, and to select mechanisms which align with knowledge on the species’ biology. We also identified the important role of irrigation in modifying habitat suitability. The refitted model accords with both distribution data and our understanding of the biology of this species, including its seasonal range dynamics. The new model identifies establishment risks to South America, Africa, the Middle East and Asia, and highlights that under current climate, Europe is only climatically suitable during warm seasons when crops are available. The modelling exercise reinforced the importance of understanding the meaning of a location record (e.g. persistent versus ephemeral populations) and of carefully exploring the role of habitat-modifying factors, such as irrigation, in allowing species to persist in otherwise inclement localities. © 2018 Springer-Verlag GmbH Germany, part of Springer Nature

Аннотация: We identified five types of moss litter in a green moss-hypnum spruce forest during alloevolution (metamorphosis) according to the habitat: peat, peaty, reduced peaty, high-ash peaty, and reduced high-ash peaty litters. During the self-development (autoevolution) of the litter, the transformation of plant matter occurs in four stages: (1) leaf (background) stage, (2) peat- and peaty-fermentative stage (browning, destruction of the litter fall and formation of platy macroaggregates), (3) humified-fermentative stage (formation of colloidal humus plasma and granular organogenic macroaggregates), and (4) the black mold humus stage (formation of colloidal humus plasma and organo-mineral humus nutty and granular macroaggregates). It was found that peat litters undergo only the initial stages of plant substrate transformation (1 and 2). The genetic profile of peaty litter is formed by three unidirectional processes (1, 2, and 3). High-ash peaty litter undergoes all the stages of plant matter transformation. The reduced analogs of peaty and high-ash peaty litter bedding were found to bypass the transitional stage 2.
