Аннотация: Environmental conditions causing stress have a significant effect on the generative organs of Scotch pine. The parameters characterizing pine pollen are subject to significant interannual variations and are closely connected with weather and climatic conditions in the period of pollen formation. Airborne pollutants affect the quality of pine pollen, which is especially apparent in the years favorable for the formation of microspores. The ability of Scotch pine pollen to germinate and form pollen tubes in the regions with different technogenic loads proved to be significantly lower than in tree stands of the background areas.

Аннотация: The morphometric parameters of trunk tissues of Scotch pine in suburban pine forests of Krasnoyarsk are studied, which grow under the long-term impact of technogenic and recreational loads in comparison with the background. Technogenic and recreational loads decrease the intensity of work of the cambium, especially towards the xylem, its duration, the cell size, and the structure of storage tissues. In pine stands of the Krasnoyarsk forest-steppe, the effect of the complex of anthropogenic stressors is weakening and degradation of forest stands and inhibition of production process at the cell and tissue levels are taking place.

Аннотация: The Russian boreal zone supports a huge terrestrial carbon pool. Moreover, it is a tremendous reservoir of wood products concentrated mainly in Siberia. The main natural disturbance in these forests is wildfire, which modifies the carbon budget and has potentially important climate feedbacks. In addition, both legal and illegal logging increase landscape complexity and affect burning conditions and fuel consumption. We investigated 100 individual sites with different histories of logging and fire on a total of 23 study areas in three different regions of Siberia to evaluate the impacts of fire and logging on fuel loads, carbon emissions, and tree regeneration in pine and larch forests. We found large variations of fire and logging effects among regions depending on growing conditions and type of logging activity. Logged areas in the Angara region had the highest surface and ground fuel loads (up to 135 t ha(-1)), mainly due to logging debris. This resulted in high carbon emissions where fires occurred on logged sites (up to 41 tC ha(-1)). The Shushenskoe/Minusinsk and Zabaikal regions are characterized by better slash removal and a smaller amount of carbon emitted to the atmosphere during fires. Illegal logging, which is widespread in the Zabaikal region, resulted in an increase in fire hazard and higher carbon emissions than legal logging. The highest fuel loads (on average 108 t ha(-1)) and carbon emissions (18-28 tC ha(-1)) in the Zabaikal region are on repeatedly burned unlogged sites where trees fell on the ground following the first fire event. Partial logging in the Shushenskoe/Minusinsk region has insufficient impact on stand density, tree mortality, and other forest conditions to substantially increase fire hazard or affect carbon stocks. Repeated fires on logged sites resulted in insufficient tree regeneration and transformation of forest to grasslands. We conclude that negative impacts of fire and logging on air quality, the carbon cycle, and ecosystem sustainability could be decreased by better slash removal in the Angara region, removal of trees killed by fire in the Zabaikal region, and tree planting after fires in drier conditions where natural regeneration is hampered by soil overheating and grass proliferation.

    Adaptation to flapping flight in different insects with complete transformation
/ D. L. Grodnitsky // Zoologicheskii Zhurnal. - 1996. - Vol. 75, Is. 5. - С. 699-700 . - ISSN 0044-5134

Аннотация: Types of flight systems in insects are described relying on the data on wing beat frequency, wing loading and other morphological and functional parameters. Each type is peculiar for one of the main endopterygote orders (Insecta: Scarabaeiformes-Oligoneoptera) which possesses the ability to fly. Origin of typical flight patterns in explained by particular features of morphology and mode of life. The wing apparatus of lacewings, scorpion flies and stone flies is characterized by the primitive features such as medium aspect ratio, low frequency and wing loading. Evolution of the flight system in beetles was strongly affected by the defensive function of thick and heavy external skeleton and thus resulted in adaptation to produce mainly lift. Dipterous flies aquired the most rapid and maneuverable flight due to particular morphological and kinematic features. Historical changes in structure and operation mode of hymenopteran wings were restricted to the necessity to transport additional loads while foraging due to social or semi-social life strategies of the species. Evolution of lepidopteran wings was determined by their heavy scale covering and the ability to regulate temperature inside thorax by means of either physiological or behavioural adaptations so that peculiar narrow-winged and broad-winged forms appeared.

    Pollution of snow cover in the impact zone of enterprises in Norilsk Industrial Area
/ A. A. Onuchin [et al.] // Contemp. Probl. Ecol. - 2014. - Vol. 7, Is. 6. - P714-722, DOI 10.1134/S1995425514060080 . - ISSN 1995-4255

Аннотация: The content of pollutants in snow samples and their composition have been determined. The quantitative indicators of the content of nickel, copper, and other heavy metals and sulfur are used to assess the nature of spatial pollution of snow cover in the impact zone of enterprises in the Norilsk Industrial Area (NIA). A map of distribution of heavy metals and sulfur in the region is compiled. It is established that the largest part of pollutants entering the atmosphere in the form of dust was deposited on the underlying surface near sources of industrial emissions (up to 7 km from them). The pollutants entering the atmosphere in the form aerosols and gases are transported over considerable distances. A greater concentration of water-soluble forms of sulfur when compared with the background are marked at a distance of more than 400 km. Calculations show that only 2% of all sulfur emissions are deposited within a radius of 250 km and the remaining portion of sulfur is incorporated into the global geochemical cycles.

    The impact of increasing fire frequency on forest transformations in southern Siberia
/ E. A. Kukavskaya [et al.] // For. Ecol. Manage. - 2016. - Vol. 382. - P225-235, DOI 10.1016/j.foreco.2016.10.015 . - ISSN 0378-1127
Аннотация: Wildfires are one of the main disturbances that impact structure, sustainability, and carbon budget of Siberian forests, as well as infrastructure and human safety. The Zabaikal region in the south of Siberia is characterized by one of the highest levels of fire activity in Russia. We have estimated fire disturbances in the Zabaikal region using both a satellite fire dataset and official fire statistics. Both datasets show a trend of increasing fire activity in the region. According to the satellite fire dataset, from 1996 to 2015 total annual area burned in the Zabaikal region varied from 0.12 to 6.33 M ha with forest area burned accounting for 0.04–5.60 M ha. The highest fire activity was observed in the central and southern parts of the Zabaikal region. About 13% (3.88 M ha) of the total forest area in the Zabaikal region was burned more than once during the 20-yr period of observation, with many sites burned multiple times. Fire disturbance was highest in forests dominated by Scots pine. We have evaluated fire impact on fuel loads, carbon emissions, and tree regeneration on about 150 sites in the light-coniferous (larch or Scots pine dominated) forests of the region. Carbon emissions from fires on repeatedly burned areas were 3–50% of those from previously undisturbed sites. Regeneration density depended on site conditions and fire characteristics. Inadequate regeneration for forest recovery was observed in Scots pine stands on dry nutrient-poor soils as well as on repeatedly-disturbed sites. This regeneration failure is leading to transformation of forests to steppe ecosystems on some sites. We conclude that negative impacts of fire disturbance on forests of the Zabaikal region could be decreased through implementation of fire prevention measures with emphasis on education of local communities as well as construction and maintenance of a fuel break system, first of all, nearby settlements and tree plantations. © 2016 Elsevier B.V.

Vegetation -- Siberia -- Climate change -- Scenario

Аннотация: The redistribution of terrestrial ecosystems and individual species is predicted to be profound under Global Climate Model simulations. We modeled the progression of potential vegetation and forest types in Siberia by the end of the twenty-first century by coupling large-scale bioclimatic models of vegetation zones and major conifer species with climatic variables and permafrost using the B1 and A2 Hadley Centre HadCM3 climate change scenarios. In the projected warmer and dryer climate, Siberian taiga forests are predicted to dramatically decrease and shift to the northeast, and forest-steppe, steppe, and novel temperate broadleaf forests are predicted to dominate most of Siberia by 2090. The permafrost should not retreat sufficiently to provide favorable habitats for dark (Pinus sibiric, Abies sibirica, and Picea obovata) taiga, and the permafrost-tolerant L. dahurica taiga should remain the dominant forest type in many current permafrost-lain areas. Water stress and fire-tolerant tree species (Pinus sylvestris and Larix spp.) should have an increased advantage over moisture-loving tree species (P. sibirica, A. sibirica, and P. obovata) in a new climate. Accumulated surface fuel loads due to increased tree mortality from drought, insects, and other factors, especially at the southern forest border and in the Siberian interior (Yakutia), together with an increase in severe fire weather, should also lead to increases in large, high-severity fires that are expected to facilitate vegetation progression toward a new equilibrium with the climate. Adaptation of the forest types and tree species to climate change in the south may be based on the genetic means of individual species and human willingness to aid migration, perhaps by seeding. Additionally, useful and viable crops could be established in agricultural lands instead of failing forests.

    Transformation of the ground cover after surface fires and estimation of pyrogenic carbon emissions in the dark-coniferous forests of Central Siberia
/ E. A. Kukavskaya [et al.] // Contemp. Probl. Ecol. - 2017. - Vol. 10, Is. 1. - P62-70, DOI 10.1134/S1995425517010073 . - ISSN 1995-4255
Аннотация: Ground fuel loads and structure in dark-coniferous forests with the dominance of Siberian pine have been studied in the Central Siberian State Nature Biosphere Reserve located in the central-taiga zone of Central Siberia. The impacts of surface fires of various forms and severity on the living ground cover are examined. It is found that fires of low to moderate severity reduce ground fuel loads from 35–49 t/ha to 26–28 t/ha, while fires of moderate to high severity reduce them to 17–18 t/ha. Consumption of down woody debris varies from 3 to 29 t/ha, depending on the prefire fuel characteristics and fire form and severity. Steady fires spreading with the fire danger index PV-1 of 3919 ± 482 result in carbon emissions of 14.0 tC/ha from fires of low to moderate severity and 24.6 tC/ha from fires of moderate to high severity. The lowest carbon emissions (10.1 tC/ha) are noted for fast-moving fires spreading with PV-1 of 1167 ± 386. © 2017, Pleiades Publishing, Ltd.

Аннотация: Разработана карта запасов органического вещества на поверхности почвы для территории Перовского участкового лесничества национального парка «Шушенский бор» на основе собственных наземных данных по запасам горючих материалов и данных лесоустройства по распределению лесных земель по различным категориям и типам леса. Составлены карты потенциальной эмиссии углерода при различных сценариях развития низовых пожаров в зависимости от их интенсивности. Установлено, что при пожарах от низкой до средней интенсивности потенциальный выход углерода на территории всего лесничества оценивается в 70,6 тыс. т, а при высокоинтенсивных пожарах — 142,9 тыс. т. Выявлен значительный вклад пирогенной эмиссии на торфяных почвах. На основе официальных данных по горимости за период с 1991 по 2016 г. и с использованием разработанных карт рассчитана фактическая эмиссия углерода при пожарах на территории равнинной части национального парка, которая составила 3,2 тыс. т. Определено, что на долю живого напочвенного покрова приходился 21 % общей эмиссии углерода, опада и подстилки — 79 %. Приведено распределение пирогенной эмиссии углерода по месяцам пожароопасного сезона. Установлено, что фактическая ежегодная эмиссия углерода за исследуемый период составила в среднем 121 т, при этом 92 % приходилось на весенний период, характеризующийся большей площадью, пройденной огнем. Рекомендовано использование результатов исследования для прогнозирования характеристик и последствий пожаров, а также для оценки влияния пожаров на региональный бюджет углерода и качество окружающей среды
The map of reserves of organic matter on the soil surface was developed for the Perovskoe forestry of Shushenskii Bor National Park with a use of our ground-based data on fuel loads as well as forest inventory data on the distribution of forested lands by different categories and forest types. We compiled the maps of potential carbon emissions for different scenarios of surface fires depending on their severity. The potential carbon emissions from fires of low to moderate severity and of high severity on the territory of the entire forestry were estimated at 70.6 and 142.9 thousand tons, respectively. A significant contribution of pyrogenic emissions from peat soils was revealed. Based on official fire data from 1991 to 2016 and using the maps developed, we calculated the actual carbon emissions from fires on the study territory of National Park which amounted to 3.2 thousand tons. It was determined that the living ground cover accounted for 21 % of the total carbon emissions, with 79 % corresponding to litter and duff. The distribution of the fire carbon emissions by months of the fire season is provided. Actual annual carbon emissions due to fires averaged was 121 tons for the period studied, with 92 % emitted due to spring fires dominating the area. The results obtained could be used to forecast fire behavior and effects as well as to estimate fire impact on regional carbon budget and environmental quality

Fuel consumption -- Fuel moisture -- Pinus sylvestris -- Surface and ground fuel loads -- Tree biomass

Аннотация: Forest fuel investigations in central and southern Siberian taiga of Scots pine forest stands dominated by lichen and feather moss ground vegetation cover revealed that total aboveground biomass varied from 13.1 to 21.0 kg/m2. Stand biomass was higher in plots in the southern taiga, while ground fuel loads were higher in the central taiga. We developed equations for fuel biomass (both aerial and ground) that could be applicable to similar pine forest sites of Central Siberia. Fuel loading variability found among plots is related to the impact and recovery time since the last wildfire and the mosaic distribution of living vegetation. Fuel consumption due to surface fires of low to high-intensities ranged from 0.95 to 3.08 kg/m2, that is, 18–74% from prefire values. The total amount of fuels available to burn in case of fire was up to 4.5–6.5 kg/m2. Moisture content of fuels (litter, lichen, feather moss) was related to weather conditions characterized by the Russian Fire Danger Index (PV-1) and FWI code of the Canadian Forest Fire Weather Index System. The data obtained provide a strong foundation for understanding and modeling fire behavior, emissions, and fire effects on ecosystem processes and carbon stocks and could be used to improve existing global and regional models that incorporate biomass and fuel characteristics. © 2019, The Author(s).

forest fires -- forest fuels -- loads -- surface forest fuels -- fire intensity -- pine forests -- Central Siberia

Аннотация: Fires in the forests of Siberia occur annually and cause enormous damage to natural resources. Therefore, studies of the natural forest fire hazard, one of the components of which are forest fuels. are relevant. The research carried out on 53 sites in the pine forests growing along the Yenisei meridian transect revealed that surface fuel loads in pine stands of different zones of Central Siberia are defined by geographical latitude and increase from the forest-steppe zone to the northern taiga subzone. The largest forest fuel loads are concentrated in the pine stands of the northern and middle taiga. Their composition is dominated by loads of duff, the fraction of which in surface fuel loads increases from the forest-steppe zone (57.4 %) to the northern taiga zone (71.3 %). The obtained dynamic equations of the reserves of grass-shrub understory over the season may be applicable to grassy types of pine forests. Combustion of surface forest fuels in pine forests during surface fires of different intensity varies from 10.8 to 31.4 t/ha, which is from 26.1 to 74.1 % of their loads before the fire. The intensity of fires determines not only the number of burned forest fuels, but also their post-pyrogenic accumulation regardless of zonal and environmental conditions. The variation of fuel loads in forest areas is related to pyrogenic effects and the recovery period after the last fire, as well as to the mosaic distribution of living ground vegetation. Equations of accumulation of surface forest fuels after fires of different intensity that can be applied to pine forests of Central Siberia are developed. A change of dominants in the ground cover and a decrease in the productivity of the grass-shrub understoiy occurs in a long-term absence of fires in pine forests. The development of moss cover contributes to the decrease in litter reserves. The data obtained on the loads of surface forest fuels and their transformation during a fire provide the basis for understanding and simulation fire behavior, estimating emissions and impacts of fires on fuel loads, and can be used for improvement the existing global and regional models.

Аннотация: Forest fuel investigations in central and southern Siberian taiga of Scots pine forest stands dominated by lichen and feather moss ground vegetation cover revealed that total aboveground biomass varied from 13.1 to 21.0 kg/m(2). Stand biomass was higher in plots in the southern taiga, while ground fuel loads were higher in the central taiga. We developed equations for fuel biomass (both aerial and ground) that could be applicable to similar pine forest sites of Central Siberia. Fuel loading variability found among plots is related to the impact and recovery time since the last wildfire and the mosaic distribution of living vegetation. Fuel consumption due to surface fires of low to high-intensities ranged from 0.95 to 3.08 kg/m(2), that is, 18-74% from prefire values. The total amount of fuels available to burn in case of fire was up to 4.5-6.5 kg/m(2). Moisture content of fuels (litter, lichen, feather moss) was related to weather conditions characterized by the Russian Fire Danger Index (PV-1) and FWI code of the Canadian Forest Fire Weather Index System. The data obtained provide a strong foundation for understanding and modeling fire behavior, emissions, and fire effects on ecosystem processes and carbon stocks and could be used to improve existing global and regional models that incorporate biomass and fuel characteristics.
