Аннотация: The Siberian moth, Dendrolimus sibiricus, Tschtv. is the most harmful defoliator of coniferous forests in North Asia. The pest has already spread over the Urals and continues moving westwards. Recently, it has been recommended for quarantine in member countries by European and Mediterranean Plant Protection Organization (EPPO). The performances of the pest on coniferous species planted in Europe were assessed on a range of potted trees corresponding to the spectrum of economically important conifers in the EU: European larch Larix decidua, Norway spruce Picea abies, Scots pine Pinus sylvestris, European black pine Pinus nigra, and the North American species: Douglas fir Pseudotsuga menziesii and grand fir Abies grandis. Larvae showed a potential to survive and complete the development on all these host tree species. Favorable hosts were grand fir, European larch, and Douglas fir that allowed higher survival, better larval development, and as a result, yielded heavier pupae and adult moths with higher longevity. Black pine was a poor host but, however, could still support larval and pupal development. Norway spruce and Scots pine had an intermediate behavior. If accidentally introduced to Europe, the Siberian moth may become especially damaging in forest stands predominated by European larch and by the North American firs. Norway spruce and especially the two-needle pines will be less prone to intensive defoliation by this species. The fact that the pest may damage the range of economically important coniferous species should be taken into account in the pest risk assessment for Europe and also for North America where the Siberian moth occurrence is considered likely.

Аннотация: Investigating the tolerance of plant reproductive systems to environmental changes has become a research priority under current climate change scenarios. Successful plant conservation requires knowledge of plant reproductive biology, particularly the meiotic characteristics of planted species. Meiosis, as part of microsporogenesis, is a critical plant developmental stage controlling future pollen quality. Meiosis in a Siberian fir (Abies sibirica) plantation, established in the Forest Arboretum of the Sukachev Institute, Russia, was studied from 2002 to 2004. The microsporogenesis pattern found for the Siberian fir appeared to be largely similar to that exhibited by other conifer species. Meiosis in the Siberian fir has the following characteristics: asynchrony, rapid progression of telophases I and II, and parallel and linear spindle arrangements at different meiosis II stages. General and specific meiosis irregularities were recorded at each stage. Some specific features of meiosis and the specific development of some irregularities were revealed. Pollen development analysis showed that irregular pollen grains made up less than 1% of all grains. The specific features of meiosis identified in fir trees growing in the Arboretum indicated low resistance of male reproductive structures to climatic changes and might account for high fir pollen sterility in this new environment.

Аннотация: The post-fire succession over the past 350 years have been analyzed so as to predict the effect of the increase in fires that is being anticipated to go hand in hand with climate change in southern Siberia, Russian Federation. Succession is defined to be the gradual supplanting of one plant community by another as conditions change either by natural means or an alter disturbance. A number of stages are being noticed in most successions on which different collections of species dominate. Finally, the last part of it is when the species composition no longer changes with time in the absence of natural or human-caused disturbances. It has been found out that the predicted increase in fires resulting from climate change in southern Siberia will probably reduce the number of larch and shade-tolerant conifers in favor of Scots pine, birch and aspen, as well as with non-tree plant communities of bushes, grasses and herbs. The continues warm and humid climate will lead to some changes in the composition of forest ecosystems that are not in favor economically. Thus, it is now necessary to have management plans for the plantations in Siberian pine to consider the increased risk of destructive surface fires and focus on fire protection.

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: Inter- and intraspecific effects of climate change were assessed for the dominant conifers of Siberia (60-140В°E and 48-75В°N): Larix spp. (L. sibirica, L. dahurica, and L. sukaczewii) and Pinus sylvestris . The approach employed a tri-variate (degree-days above 5В°C, degree-days below 0В°C, and a moisture index) estimate of the climatic envelope within which exists the actual ecological distribution of a species and their constituent climatypes (genotypes physiologically attuned to similar environments). Limits of the actual ecological distribution were approximated by reducing the climatic envelope according to effects of permafrost and interspecific competition. Climatypes were mapped within the climatic envelope according to the climatic interval that must separate populations for reasonable assurance of genetic differentiation. This interval was calculated from response functions that related 13-year growth and survival of a species to the difference in climate between the provenance of a climatype and the climate of numerous test sites distributed across Russia. Mapping species' distributions and their climatypes was done for the contemporary climate and for future climates predicted by the HadCM3GGa1 scenario of Hadley Centre. The results showed that if the forests of the future are to reflect the adaptedness of today, the distribution of species will shift and genotypes within species will be redistributed. Some contemporary climatypes are projected to disappear from Siberia while others common elsewhere would evolve. To mitigate these effects, climatypes should be transferred today to the expected future location of their climatic optima, a distance that is likely to approach 700-1200 km for these species.

Аннотация: Presented are the dendroclimatic research results on annual growth rings of spruce, fir, pine, birch and aspen growing in the middle taiga subzone of Central Siberia. The study established the general annual growth ring variability patterns for the conifers (spruce and fir) as well as for the hardwoods (birch and aspen), with the correlation coefficients between their chronologies estimated at 0.38 and 0.46 (p < 0.001), respectively. It is shown that under the given conditions the influence of the climatic factors accounts not more than for 53.5% of the variability in radial increment. For pine this influence is less clearly pronounced because of the content of the more mixed (compared with the other species of this territory) climatic signal. It is found that the temperature conditions of June are of first importance for all species under investigation. For birch and aspen the dependence of radial increment on the amount of precipitation in June is explained by moisture depletion at the period of the most active growth. В© 2009.

Аннотация: Vegetation models are essential tools for projecting large-scale land-cover response to changing climate, which is expected to alter the distribution of biomes and individual species. A large-scale bioclimatic envelope model (RuBCliM) and an individual species based gap model (UVAFME) are used to simulate the Russian forests under current and future climate for two greenhouse gas emissions scenarios. Results for current conditions are compared between models and assessed against two independent maps of Russian forest biomes and dominant tree species. Comparisons measured with kappa statistics indicate good agreement between the models (kappa values from 0.76 to 0.69), as well as between the model results and two observationbased maps for both species presence and absence (kappa values from 0.70 to 0.43). Agreement between these multiple types of data on forest distribution provides confidence in the projected forest response to changing climate. For future conditions, both models indicate a shift in the dominant biomes from conifers to deciduous leaved species. These projections have implications for feedbacks between the energy budget, carbon cycle, and land cover in the boreal system. The distinct biome and species changes emphasize the need for continued investigation of this landmass that has the size necessary to influence regional and global climate.

Аннотация: n recent decades there has been an increase in the radial growth of Larix sibirica Ledeb., Pinus sibirica Du Tour, and Abies sibirica in the Kuznetsk Alatau alpine forest-tundra ecotone. Larch growth correlates positively with summer temperatures; cedar and fir growth is determined by temperature, precipitation, and sunshine duration. It is shown that the current growth of maturing larch trees is about 55% higher than that of a similar age group observed 200 years ago. The rate of larch advancement along the height gradient is estimated at 1 m/10 years. A periodical limitation of the radial growth in fir by winter and summer temperatures is found; the strongest correlation is revealed with summer temperatures (r = 0.9). The growth rate of all conifers correlates highly with the concentration of CO2 in the atmosphere (r = 0.42–0.84). Increased winter temperatures induce the transformation of the elfin forms in larch and cedar (the early 1970s) and later fir (the early 1980s) into vertical forms. © 2015, Pleiades Publishing, Ltd.

Аннотация: Siberian pine (Pinus sibirica) and fir (Abies sibirica) (so called “dark needle conifers”, DNC) showed decreased radial growth increment within the Lake Baikal watershed since the 1980s with increasing mortality recorded since the year 2000. Tree ring width was strongly correlated with vapor pressure deficit, aridity and root zone moisture. Water stress from droughts made trees more susceptible to insect attacks causing mortality in about 10% of DNC stands within the Lake Baikal watershed. Within Siberia DNC mortality increased in the southern part of the DNC range. Biogeographically, tree mortality was located within the DNC – forest-steppes transition. Tree mortality was significantly correlated with drought and soil moisture anomalies. Within the interior of the DNC range mortality occurred within relief features with high water stress risk (i.e., steep convex south facing slopes with shallow well-drained soils). In general, DNC mortality in Siberia was induced by increased aridity and severe drought (inciting factors) in synergy with biotic attacks (contributing factor). In future climate scenarios with predicted increase in aridity DNC could be eliminated from the southern part of its current range and will be replaced by drought-resistant conifers and broadleaf species (e.g., Larix sibirica, Pinus silvestris, and Betula pubescence). © 2016

Аннотация: The spatial and temporal dynamics of fir stands damage caused by a large-scale outbreak of the Siberian silk moth (Dendrolimus sibiricus Tschetv.) in the Altai Mountains has been studied using remote sensing and GIS methods. It is ascertained that forest damages are dissimilar relative to the surface features. The pest outbreak initially occurred on the southwest slopes with mean values of 10° and elevation of 400 m asl. The damages further extended both upward and downward, involving slopes of high steepness and the eastern exposure. The total area of the dead stands comprised 6000 ha, 45% of which were lost due to secondary pest (xylophagous insects) attacks. It is indicated that the use of remote sensing made it possible to determine the beginning of a pest outbreak with one-decade precision. The Siberian silk moth large-scale outbreak occurred against an increase in air temperatures, a decrease in precipitation, and a reduction in late frosts. The tree plants weakened by the Siberian silk moth and water stress were affected by xylophagous insect attacks. The observed and predicted warming and climate aridity increase will facilitate Siberian silk moth outbreaks both within its range and northward of the current margins of the range. © 2016, Pleiades Publishing, Ltd.

Аннотация: The study is aimed at investigation of ophiostomatoid fungi, associated with the four-eyed fir bark beetle (Polygraphus proximus Blandford, Coleoptera, Curculionidae)—an invasive pest of Siberian fir Abies sibirica. In the Russian Far East, eight fungal species are associated with this bark beetle. All of these fungi (except Leptographium taigense and Grosmannia europhioides) were brought by P. proximus to its secondary range (Southern Siberia and Moscow oblast). In the secondary range, a complex of ophiostomatoid fungi connected with P. proximus consists mainly of the Far Eastern species adapted to new habitats. Phytopathogenic activity of the fungi associated with bark beetle was studied. G. aoshimae and Ophiostoma nikkoense demonstrated high phytopathogenic activity after inoculation into phloem of Siberian fir. The culture of G. aoshimae and O. subalpinum produced extensive necroses in stems of Siberian larch Larix sibirica. In general, G. aoshimae is the main fungal associate of P. proximus, considering the frequency and stability of its occurrence in samples, as well as its aggressiveness toward coniferous species of Southern Siberia. It demonstrated high aggressiveness toward Siberian fir and Siberian larch; Scots pine Pinus sylvestris is also susceptible to this fungus. Siberian spruce Picea obovata and Siberian pine Pinus sibirica are resistant. There is a high possibility of P. proximus mycobiota enrichment with a complex of fungi connected with fir sawyer beetle Monochamus urussovi Fisch., an aboriginal pest of fir in Siberia. © 2018, Pleiades Publishing, Ltd.

Аннотация: Trees comprising high mountain forests have different requirements for site conditions (such as the water supply), thus current climate warming leads to varying reactions of upper forest boundaries depending on the site conditions and ecophysiological features of species. Positive reactions to an increasing heat supply during vegetative season may be hindered for drought-sensitive species by a water deficit in a cold environment, particularly during late winter or early spring. We investigated the radial growth of dark coniferous forest species Siberian stone pine (Pinus sibirica Du Tour) and Siberian fir (Abies sibirica Ledeb.) growing on slopes of different orientation (south-west, east, and north) near the upper forest boundary in an area undergoing fast climate warming: the Western Sayan Mountains (South Siberia, Russia), near a massive water reservoir. Correlations of tree-ring width chronologies with moving 21-day temperature series were used to more precisely determine the timing of temperature influence; an analysis of extreme and optimal years and multifactor regression modeling were applied to assess the most favorable/unfavorable thermal conditions in the study area and to estimate the tree growth reaction to the current climatic trends, respectively. Despite relatively low variation in growth (standard deviation <0.2), a significant common climatic signal in tree-ring width was found at all sampling sites. On the shaded northern slopes, P. sibirica is only mildly limited by summer temperatures and has a low similarity (correlations and synchronicity of extreme/optimal years) with other sites. Conversely, the growth of A. sibirica and P. sibirica on two sunlit slopes is similar (r = 0.44–0.81) and has a common pattern of regulation by temperatures before (r = ?0.17…?80.40; April 3 – May 4 on average) and more significantly during vegetative season (r = 0.31…0.44; May 17 – August 27 on average). We hypothesize that both species, being drought-sensitive, undergo water stress in the early spring, and exposition of previous years’ needles to severe temperature variation may lead to partial defoliation and xylem embolism, thus suppressing growth. The patterns of climatic response and species distribution on slopes indicate that A. sibirica is more sensitive to this physiological drought and needs gentler slopes than P. sibirica. Temperature increase in the study area during the last decades have occured about five times faster in the early spring (being enhanced by the reservoir) than in summer. This combination of spring and summer warming leads to an increase in P. sibirica radial growth on the northern slope and the stable growth of both species on sunlit slopes, i.e. providing a tentatively optimistic assessment of the dark coniferous forests’ near future in the region. © 2019 Elsevier B.V.

Аннотация: Quantitative wood anatomy (QWA) is a growing field of dendrochronology that allows obtaining a large number of parameters as the number, size and spatial arrangement of cellular elements, elements that highlight the adjustments of trees to their environment. In this work, we presented the free/libre open-source software AutoCellRow (ACR), a ready-to-use tool for automatic QWA in conifers. The ACR analyzes radial files of cells on cross-sections views of tree rings and provides automatic measurements of different cell parameters (e.g., lumen radial diameter, double cell wall thickness and cell radial diameter) for each cell along the selected radial file. The ACR measurements are based on high performed image analysis of xylem cells. The accuracy of the software measurements was tested in cross-sections of five conifer species from a semi-arid area of southern Siberia, and compared with measurements obtained by a semiautomatic tool. Our results suggested high accuracy in the ACR cell traits measurements, facilitating and speeding the analysis of quantitative wood anatomy in conifers over radial files of cells. © 2020 Elsevier GmbH

Аннотация: Abstract: The goal was to find out how consistent the elemental distributions in tree rings are. The dataset was received for a long-term afforestation experiment that included even soil conditions and a variety of conifers (Scots pine, Norway spruce, Siberian pine, and Siberian larch) growing in pure stands. The stands are a part of a long-term experiment of the Institute of Forest SB RAS. The experiment is located in the vicinity of Krasnoyarsk city. Relative contents of elements (counts) were received through the scanning facility of Itrax Multiscanner (COX Analytical Systems). Every element was attributed with two variables: concentration of counts and quantity of counts. A cluster analysis was performed in a four-dimensional space of standard deviations and linear slopes of the variables. The elements studied non-randomly distribute over the clusters. Three elements (Ca, Co, and P) display a high consistency of distribution parameters in tree rings as they cluster largely irrespective of species. A few elements (Mn, Pb, Cl, Cr, Ni, Sr, and W) cluster consistently within species. Therefore, for the first time, it was found that the species factor does not affect the distribution of some elements, but significantly affects the distribution of others. © 2021, Pleiades Publishing, Ltd.

Аннотация: Abstract—: Winter CO2 fluxes in Central Siberian ecosystems have been measured using different methodological approaches: dynamic chamber measurements at the soil surface under snowpack (Fsoil) and at the upper snowpack surface (Fsnow), static estimates based on measured CO2 concentrations and conductance properties of the snowpack (Fdiff), and calculations of CO2 efflux rates based on the eddy covariance technique (Fec). The results of measurements are analyzed and discussed with respect to the significance of differences between them and the applicability and limitations of the corresponding methods. The data are presented on winter CO2 efflux rates in five major ecosystem types of Central Siberia: lichen pine forest, lichen–moss pine forest, mixed forest, dark conifer forest, and raised pine bog. © 2021, Pleiades Publishing, Ltd.
