Аннотация: Problem of wildfires has not been resolved anywhere in the world. Mere increase of technical power does not lead to desirable results. Forests of developed countries burn as actively as those in Africa or in Russia. The main reasons of wildfire problem are as follows: (1) Constant wandering of dry seasons over the planet causing outbreaks of wildfires. (2) Unpredicted self-development of ordinary wildfires into awful fire disasters. (3) Difficulties in delivery and use of heavy machines on hardly accessible territories. (4) Absence of a perfect technique for economic evaluation of how effectively the wildfire control system works. (5) Absence of the system of payments encouraging wildfire fighters. To solve the problem of wildfires in Russia it is necessary to: (1) Create the Russian wildfire behaviour and fire effects prediction system on the basis of the developed classification of vegetation fuels and methods of their mapping as well as maximum utilization of forest inventory information and Geographic Information System (GIS). (2) Elaborate a technique of proper wildfire monitoring including estimation of vegetation damage. (3) Improve daily rating of regional fire danger. (4) Improve fire-preventive arrangement of the territory covered by vegetation, the main goal being creation of favourable conditions for active fire management. (5) Choose the main direction in elaboration of fire-fighting means and methods taking into account their universality, simplicity, reliability, etc. (6) Elaborate an improved technique for estimation of economic effectiveness of the wildfire control system. (7) Develop international cooperation of scientists and professionals in fire management.

Аннотация: A model of the population dynamics of insects has been developed, which takes into account the food consumption by insects and the reaction of food plants to the damage. Equations have been derived that describe the relationship between the coefficient of insect reproduction, the weight of females, the energetic effectiveness of the food consumption by insects, and the reaction of food plants. The scenarios of population outbreaks have been analyzed as a function of the weight of females in the stable state. The results of modeling have been compared with the data of natural observations.

Аннотация: Efficient syntheses of (ZE)-5,7-dodecadienol, a pheromone component of the Siberian moth, Dendrolimus superans sibiricus, and (E,Z)-10,12-hexadecadienol, a pheromone component of various Lepidoptera pheromones, were accomplished by cis reduction of the corresponding enynols with activated zinc. The most energetic reagent was zinc galvanized with copper and silver (Zn/Cu/Ag) that achieved rapid and high-yield reduction in methanol-water. The stereoselectivity of semihydrogenation was greater than or equal to98%. A process whereby zinc dust was continuously activated throughout the reduction with an acid was also satisfactory (95-98% cis). Field evaluation of the 1:1 mixture of (Z,E)-5,7-dodecadienol and (Z,E)-5,7-dodecadienal with the Siberian moth in Russia showed that the rubber septa pretreated with compound and stored at -80 degreesC were as effective as freshly treated septa. Moth responses to septa aged in open air indicated that lure effectiveness declined significantly after 2 weeks of aging. Thus, if rubber septa are used as pheromone dispensers in Siberian moth traps monitoring, they should be replaced biweekly with fresh septa for optimal trap effectiveness.

Аннотация: Growth and survival of eight populations of Larix sukaczewii Dylis and one of both Larix sibirica Ledeb. and Larix gmelinii (Rupr.) Rupr. were used to assess the effectiveness of climate transfer functions for predicting the 13-year performance of Eurasian provenances introduced to Alberta. Quadratic regression models showed that transfer distances for five climate variables (mean annual temperature, degree-days 0 C, mean temperature in the coldest month, ratio of the mean annual temperature to mean annual precipitation, and the summer-winter temperature range) were particularly effective in predicting height and survival. Optimal transfer distances did not differ significantly from zero, and as a result, the best growth and survival in Alberta should be obtained by matching the provenance climate to that of the planting site for the five variables. Verification of the climate transfer functions with independent data from Russian provenance tests were strongly supportive. The results demonstrate the effectiveness of climate transfer functions for describing the response of plant populations to the environment and thereby have practical implications in reforestation.

Аннотация: Leguminous green manure is an important source of nitrogen (N) and carbon (C) in cropping systems. The fast turnover of leguminous green manure enables it to release N quickly, but limits its effectiveness in maintaining soil organic C content. Converting leguminous green manure into biochar facilitates its use as a soil amendment. In this study, we assessed how the conversion of leguminous green manure (Sesbania roxburghii) into biochar altered its chemical composition and subsequent C and N mineralization. Biomass was charred along a temperature gradient from 200 to 500. °C. Using nuclear magnetic resonance and near-edge X-ray adsorption fine structure spectroscopy, we found that both C and N became enriched in aromatic and heterocyclic aromatic structures in biochar, and this structural change led to a reduction in C and N mineralization rates. The mineralized C decreased from 32.7% of the added C of raw biomass to <. 0.5% of that of biochar at charring temperatures above 400. °C. N release shifted from N mineralization in raw biomass to N immobilization at charring temperatures at 500. °C. As such, soil amended with biochar produced at charring temperatures exceeding 400. °C demonstrated a 25% decrease in dry shoot biomass compared with unamended soil. The results indicated that the C stability of leguminous green manure can be achieved by converting raw material into biochar, but that the charring process may limit it to providing N. © 2014 Elsevier B.V.

Аннотация: The ground and excited states of the pheromone molecules produced by xylophagous insects (the bark beetle Ips typographus L., the black fir sawyer beetle Monochamus urussovi Fisch., and the black pine sawyer M. galloprovincialis Oliv.) were modeled using a quantum chemical method utilizing DFT (density functional theory) with the B3LYP functional. The absorption wavelengths (energies) and dipole moments were calculated; the transitions of electrons from occupied to empty molecular orbitals were considered. The computed data were used to assess the stability of pheromone molecules exposed to environmental factors, such as solar radiation and humidity. © 2017, Pleiades Publishing, Inc.

Аннотация: BackgroundDe novo assembling of large genomes, such as in conifers (similar to 12-30 Gbp), which also consist of similar to 80% of repetitive DNA, is a very complex and computationally intense endeavor. One of the main problems in assembling such genomes lays in computing limitations of nucleotide sequence assembly programs (DNA assemblers). As a rule, modern assemblers are usually designed to assemble genomes with a length not exceeding the length of the human genome (3.24 Gbp). Most assemblers cannot handle the amount of input sequence data required to provide sufficient coverage needed for a high-quality assembly.ResultsAn original stepwise method of de novo assembly by parts (sets), which allows to bypass the limitations of modern assemblers associated with a huge amount of data being processed, is presented in this paper. The results of numerical assembling experiments conducted using the model plant Arabidopsis thaliana, Prunus persica (peach) and four most popular assemblers, ABySS, SOAPdenovo, SPAdes, and CLC Assembly Cell, showed the validity and effectiveness of the proposed stepwise assembling method.ConclusionUsing the new stepwise de novo assembling method presented in the paper, the genome of Siberian larch, Larix sibirica Ledeb. (12.34 Gbp) was completely assembled de novo by the CLC Assembly Cell assembler. It is the first genome assembly for larch species in addition to only five other conifer genomes sequenced and assembled for Picea abies, Picea glauca, Pinus taeda, Pinus lambertiana, and Pseudotsuga menziesii var. menziesii.

Аннотация: Background: Assessment of the reasons for the ambiguous influence of forests on the structure of the water balance is the subject of heated debate among forest hydrologists. Influencing the components of total evaporation, forest vegetation makes a significant contribution to the process of runoff formation, but this process has specific features in different geographical zones. The issues of the influence of forest vegetation on river runoff in the zonal aspect have not been sufficiently studied. Results: Based on the analysis of the dependence of river runoff on forest cover, using the example of nine catchments located in the forest-tundra, northern and middle taiga of Northern Eurasia, it is shown that the share of forest cover in the total catchment area (percentage of forest cover, FCP) has different effects on runoff formation. Numerical experiments with the developed empirical models have shown that an increase in forest cover in the catchment area in northern latitudes contributes to an increase in runoff, while in the southern direction (in the middle taiga) extensive woody cover of catchments “works” to reduce runoff. The effectiveness of geographical zonality in regards to the influence of forests on runoff is more pronounced in the forest-tundra zone than in the zones of northern and middle taiga. Conclusion: The study of this problem allowed us to analyze various aspects of the hydrological role of forests, and to show that forest ecosystems, depending on environmental conditions and the spatial distribution of forest cover, can transform water regimes in different ways. Despite the fact that the process of river runoff formation is controlled by many factors, such as temperature conditions, precipitation regime, geomorphology and the presence of permafrost, the models obtained allow us to reveal general trends in the dependence of the annual river runoff on the percentage of forest cover, at the level of catchments. The results obtained are consistent with the concept of geographic determinism, which explains the contradictions that exist in assessing the hydrological role of forests in various geographical and climatic conditions. The results of the study may serve as the basis for regulation of the forest cover of northern Eurasian river basins in order to obtain the desired hydrological effect depending on environmental and economic conditions. © 2021, The Author(s).

Аннотация: This study examined the effectiveness of decontamination of industrial cyanide-containing water using mycelium-based lignocellulosic materials. These results suggest that fungi biomass and plant substrates can be used successfully in the treatment of wastewater contaminated by cyanide. Fungi were isolated from old wood samples taken from a tailing dam with high cyanide content (more than 20 years in semi-submerged condition). All isolated fungi belonged to the genus Fusarium. Fusarium oxysporum Schltdl is most effective for biodegradation of cyanide-containing wastewaters (even at low temperatures). The most optimal lignocellulosic composition for production of mycelium-based biomaterial for biodegradation of cyanide wastewater consists of a uniform ratio of Siberian pine sawdust and wheat straw. The high efficiency of mycelium-based materials has been experimentally proven in vitro at 15-25 ° C. New fungal biomaterials are provide decrease in the concentration of cyanide ions to 79% (P <0.001). Large-scale cultivation of fungi biomass was carried out by the periodic liquid-phase cultivation. The submerged biomass from bioreactor was used as an inoculum for the production of mycelium-based materials for bioremediation of cyanide wastewater in situ (gold mine tailing). © 2021 Trans Tech Publications Ltd, Switzerland.

Аннотация: На территории Средней Сибири ежегодно возникают сотни лесных пожаров, распространяющиеся на огромные площади, а в последние десятилетия число их и пройденная площадь значительно возросли, также увеличилась средняя площадь одного пожара. Все это свидетельствует о недостаточной эффективности организации охраны лесов. Максимальное число пожаров приходится на Нижнеангарский таежный район с преобладающими сосновыми насаждениями, в которых с середины прошлого века активно проводятся сплошные рубки. Наибольшая площадь, пройденная лесными пожарами, зарегистрирована в Среднесибирском плоскогорном таежном районе, где леса малодоступны и выделена зона контроля. Здесь также зафиксировано самое большое количество пожаров от гроз (93.1 %). В основном крупные катастрофические пожары действовали в зоне контроля. Анализ метеофакторов, влияющих на возникновение лесных пожаров на примере отдельных лесных районов, и полученные регрессионные модели зависимости числа пожаров от температуры и осадков в современных условиях позволили установить главные причины возникновения пожаров: интенсивное хозяйственное освоение лесных территорий, появление значительного количества антропогенных источников огня и увеличение грозовой активности вследствие изменения климата. Использование регрессионной модели связи количества лесных пожаров со средней температурой воздуха и суммой осадков за пожароопасный сезон позволяет качественно оценить систему охраны лесов от лесных пожаров. В то же время в отдельных лесных районах наблюдается снижение эффективности охраны лесов от пожаров, рост числа которых обусловлен климатическими изменениями.
On the territory of Central Siberia, hundreds of forest fires occur annually, spreading over vast areas. An analysis of the dynamics of forest fires showed that in recent decades the number of fires and the burned area have increased significantly. The average area of one fire has also increased, which indicates the insufficient effectiveness of the organization of forest fire protection. The maximum number of fires occurs in the Nizhneangarskiy taiga region, where pine forests predominate, in which cutting have been actively carried out since the middle of the last century. The largest burned area was registered in the Central Siberian plateau taiga region, where forests are inaccessible and a zone control by only remote-sensing instruments has been allocated. The largest number of fires from thunderstorms was also recorded in this forest region (93.1 %). The main number of large and catastrophic fires operated in the control zone. The meteorological factors influencing the occurrence of forest fires are analyzed and regression models of the dependence of the number of forest fires on temperature and precipitation for different forest regions are obtained. The main causes of fires are the emergence of a large number of fires sources due to the intensive economic development of forest areas and increased thunderstorm activity due to climate change. The use of a regression model of the relationship between the number of forest fires and the average air temperature and the amount of precipitation for the fire season allows to qualitatively estimate the system of protecting forests from forest fires. At the same time, in some forest regions, there is a decrease in the effectiveness of protecting forests from fires, the increase in the number of which is due to climate change.
