Surface energy balance of the Sygyktinsky Glacier, south Eastern Siberia, during the ablation period and its sensitivity to meteorological fluctuations
Authors: Osipov Eduard Y. , Osipova Olga P.
Published: October 2021

The physically based melt of the low elevation Eastern Siberian glaciers is poorly understood due to the lack of direct micrometeorological studies. We used an automatic meteorological station to record the meteorological and energy characteristics of the Sygyktinsky Glacier, south Eastern Siberia (56.8° N, 117.4° E, 2,560 m a.s.l.), during two ablation seasons and computed the surface energy balance (SEB) for 30-min intervals. The glacier ablation was both modeled and measured by stakes and a thermistor cable. The net radiation (Rnet) was the main contributor (71–75 W m−2, 89–95%) to the SEB (79 W m−2, 100%), followed by sensible (2–4 W m−2, 3–5%) and latent (2–3 W m−2, 2–4%) heat fluxes. The net shortwave radiation was the main positive component of Rnet, while the net longwave radiation was weak and either negative (− 15 W m−2in 2019) or positive (4 W m−2in 2020). The small proportion of turbulent fluxes in the SEB is explained by the low wind speed (1.2 m s−1). The glacier ablation was found to be more sensitive to changes in shortwave radiation and wind speed, suggesting the need to consider the atmospheric conditions of the ablation period (summer snowfalls, cloudiness, wind speed) when analyzing long-term trends in glacial changes.

Epithelial–mesenchymal transition and its transcription factors
Authors: Debnath Pallabi , Huirem Rohit Singh , Dutta Paloma , Palchaudhuri Santanu
Published: October 2021

Epithelial–mesenchymal transition or EMT is an extremely dynamic process involved in conversion of epithelial cells into mesenchymal cells, stimulated by an ensemble of signaling pathways, leading to change in cellular morphology, suppression of epithelial characters and acquisition of properties such as enhanced cell motility and invasiveness, reduced cell death by apoptosis, resistance to chemotherapeutic drugs etc. Significantly, EMT has been found to play a crucial role during embryonic development, tissue fibrosis and would healing, as well as during cancer metastasis. Over the years, work from various laboratories have identified a rather large number of transcription factors (TFs) including the master regulators of EMT, with the ability to regulate the EMT process directly. In this review, we put together these EMT TFs and discussed their role in the process. We have also tried to focus on their mechanism of action, their interdependency, and the large regulatory network they form. Subsequently, it has become clear that the composition and structure of the transcriptional regulatory network behind EMT probably varies based upon various physiological and pathological contexts, or even in a cell/tissue type-dependent manner.

Context. Isotopic fractionation is an important tool for investigating the chemical history of our Solar System. In particular, the isotopic fraction of nitrogen (14N/15N) is lower in comets and other pristine Solar System bodies with respect to the value measured for the protosolar nebula, suggesting a local chemical enrichment of 15N during the formation of the Solar System. Therefore, interferometric studies of nitrogen fractionation in Solar System precursors are needed for us to obtain clues about our astrochemical origins.

Aims. In this work we have investigated the variation in the 14N/15N ratio in one of the closest analogues of the environment in which the Solar System was born: the protocluster OMC-2 FIR4. We present the first comparison at high angular resolution between HCN and N2H+ using interferometric data.

Methods. We analysed observations of the HCN isotopologues H13CN and HC15N in the OMC-2 FIR4 protocluster. Specifically, we observed the transitions H13CN (1−0) and HC15N (1−0) with the NOrthern Extended Millimeter Array (NOEMA) within the context of the IRAM Seeds Of Life In Space (SOLIS) Large Program. We combined our results with analysis of archival data obtained with the Atacama Large Millimeter Array of N2H+ and its 15N isotopologues.

Results. Our results show a small regional variation in the 14N/15N ratio for HCN, from ~250 to 500. The ratios in the central regions of FIR4, where the candidate protostars are located, are largely consistent with one another and within that range (~300). They also show little variation from the part of the protocluster known to harbour a high cosmic-ray ionisation rate to the portion with a lower rate. We also found a small variation in the 14N/15N ratio of N2H+ across different regions, from ~200 to ~400.

Conclusions. These results suggest that local changes in the physical parameters occurring on the small linear scales probed by our observations in the protocluster do not seem to affect the 14N/15N ratio in either HCN or N2H+ and hence that this is independent of the molecule used. Moreover, the high level of irradiation due to cosmic rays does not affect the N fractionation either.
Influence of Zostera marina L. and Z. noltei Hornem. (Zosterales: Liliopsida) on the composition, species richness and coenotic diversity of the phytobenthos of the Azov Sea
Authors: Afanasyev Dmitry , Akatov Valery
Published: October 2021

The influence of marine higher plants Zostera marina and Z. noltei on the composition, species richness and coenotic diversity of the phytobenthos of sandy and silty soils of the Taman Bay in the Azov Sea at the depths from 0.5 to 3 m has been investigated. It is shown that 1) macrophytobenthic communities with a high degree of Z. noltei and Z. marina dominance (DD), both at very small and relatively large sites, are characterized by lower species richness than the communities with low DD; 2) that being said, for the majority of co-occurring species it is possible to grow in coenoses with any DD; 3) accordingly, about the same number of species can grow at the small community sites with low DD and at the larger sites with high DD; 4) DD has little to no influence on the species diversification of coenoses. However, both the growth of Zostera marina and Z. noltei and the decrease in their participation can lead to considerable drop in occurrence of some macroalgae species or to disappearance of those species from a community.
Integrated ecological education in the annual field courses to West Siberia
Authors: Barsukov Pavel
Published: October 2021

Since 1995 soil field courses across bioclimatic zones in West Siberia were organized by a group of scientists from Siberia and Germany. These were soon transformed into annual (once a year) ecological field courses, which we believe successfully promote ecological education among students and young scientists from different countries. The courses were focused on virgin ecosystems undisturbed by anthropogenic influences, its individual components and more importantly multiple relationships between the components. The paper describes the main features of the field courses, the organization and changes in the content over the period of 2012-2019. This includes a short description of the field course route, interdisciplinary teaching approaches, the dynamics in number of participants. Special attention is paid to the evaluation of the courses by participants and results of the tests taken by student participants at the end of courses. Further proposals for improving the field courses are suggested.

Authors: Denisova Gulnora , Rahimov Safarbek
Published: October 2021

Individuals ofDracocephalum nutansL. have been studied at different altitude levels from 460 to 2437 m above the level seas. The influence of the height gradient on morphological characters has been shown: the number of generative and vegetative shoots, the height of the generative shoot, the length and width of the leaf blade, length of its petiole, and inflorescence length. It was found that the height gradient has the greatest influence on the height of the generative shoot and the length of the inflorescence. When individuals grow higher along the altitude gradient, the height of the generative shoot and the length of the inflorescence decrease. The fluctuation of the average values of the traits ofD. nutansin a wide range was established. The intrapopulation analysis ofD. nutansindividuals does not depend on the height factor.

Authors: Glazunov Valerii , Nikolaenko Svetlana , Senator Stepan
Published: October 2021

The protected areas of the Nadym district are currently represented by only one nature reserve «Nadymskiy». This does not protect the biodiversity of the region. In 2020, we conducted a survey of the Nadym district in order to find new sites for the creation of protected areas. As a result, 7 new protected areas have been proposed: a natural park, a wildlife sanctuary and 5 natural monuments, including three lakes with a rare protected species of spore plants – Isoetes echinospora. The proposed protected areas cover the biodiversity of all natural zones of the Nadym district: tundra, forest-tundra and northern taiga. Some of the protected areas are of great historical and cultural importance for the aborigines.

Published: October 2021

The aim of this work was to identify and analyze the ontogenetic and spatial structure of steppe plant Clausia aprica (Stephan) Korn.-Tr. (Brassicaceae) cenopopulations at the border of distribution. The study of cenopopulations and their habitat conditions was conducted at 2006–2021 in Samara, Volgograd, and Orenburg Oblasts (Russian Federation). For the first time determined the polyvariance of development of individuals, the duration of ontogenetic stages and complete ontogenesis, peculiarities of spatial location and evaluation of running window methods. A table of prohibitions and resolutions of transitions between ontogenetic states was compiled for C. aprica ontogenesis. It was found that permissions of transitions between ontogenetic states are 37.8%. In natural cenopopulations, mutual transitions of individuals from one ontogenetic state to another has adaptive significance and determines the dynamics of the ontogenetic structure. At intervals of 6-8 years, a slight increase in the number of C. aprica individuals is observed in the populations, which is ensured by the efficiency of seed reproduction. Thus, self-maintenance and self-renewal of species populations is possible in case of low level of anthropogenic impact on vegetation cover of territories.

The leaves and inflorescences of the plants contain flavonols, catechins, tannins, carotenoids, pectin substances. High content of phenolic compounds was found in Artemisia dracunculus and Achillea millefolium (352.34 – 398.99 mg/g of DW). The highest level of catechins was registered in inflorescences (8.01 mg/g) and leaves (4.58 mg/g) of Artemisia absinthium. The content of pectin substances in the studied plants was quite high, with the biggest share of protopectins (50.6 – 95.9 mg/g). The maximum quantity of pectins was found in the leaves and inflorescences of Leucanthemum vulgare (11.2-12.7 mg/g), protopectins – in the leaves of Tanacetum vulgare (95.9 mg/g). The highest content of carotenoids was found in the leaves of plants, except for Leucanthemum vulgare. The highest antioxidant activity was recorded for water-ethanol extracts from leaves of Achillea millefolium (up to 1.09 mg/g) and inflorescences of Artemisia dracunculus (0.94 mg/g) plants due to the increased content of phenolic compounds, in particular flavonols and tannins, compared to the other species.

Published: October 2021

A study on some morphological characteristics and the set and levels of phenolic compounds was performed for the first time on Spiraea hypericifolia L. (Rosaceae Juss.) growing under natural conditions in the Novosibirsk region (four sites). Two phenotypic varieties of S. hypericifolia were identified. Twenty-three phenolic compounds were found in aqueous-ethanol extracts from S. hypericifolia leaves by high-performance liquid chromatography. Chlorogenic, p-hydroxybenzoic, and p-coumaric acids and quercetin, hyperoside, isoquercitrin, avicularin, rutin, and astragalin were identified among them. Hyperoside (6.7–20.5 mg/g) is the main phenolic compound in S. hypericifolia leaves. Flavonoid aglycones were prepared from the leaves by hydrochloric-acid hydrolysis of the aqueous-ethanol extracts (1:1). Three flavonol aglycones (quercetin, kaempferol, and isorhamnetin) were identified in the extract hydrolysates from S. hypericifolia leaves by chromatographic analysis. Quercetin glycosides proved to be predominant phenolic compounds in all the extract hydrolysates. A comparative analysis was performed on the levels of phenolic compounds in leaves among S. hypericifolia from the different sites and between the two varieties of S. hypericifolia. It was revealed that an increase in plant size by approximately twofold correlates with a decrease in concentrations of the identified flavonoids and phenolcarboxylic acids in S. hypericifolia leaves.

Authors: Lagunova Elena , Larina Olga
Published: October 2021

The flora of vascular plants in the city of Abakan (Republic of Khakassia, Russia) is represented by 459 taxa belonging to 69 families and 325 genera. Angiosperms are predominant in the flora of higher vascular plants and are represented by 451 species (98.3% of the entire city flora), including monocotyledons (104 species, 22.7%) and dicotyledons (347 species, 75.6%). According to these indicators, the flora of this city belongs to temperate floras of the Holarctic. The presence of 24 single-species families in the Abakan flora is related to the observed poor state of environment-forming factors, which prevents the adaptation of species under the new transformed conditions of the urbanized environment. Lichens in Abakan are represented by 33 species affiliated with 18 genera and 8 families. There are 125 mushroom species belonging to 75 genera, 34 families, 6 orders, and a single class, Agaricomycetes.

Published: October 2021

Gymnadenia conopsea (Fragrant orchid) is a widespread model species for the study of polymorphism in the European part of Russia and abroad. Flow cytometry refers to rapid methods effective for assessing the structure of a population by DNA size estimation. However, this method is only available in habitats with close proximity to the place of the experiment, because this indicator is determined only in fresh leaves. A small population of G. conopsea in the industrial area adjacent to the Novosibirsk urban agglomeration in the Novosibirsk Region (NR) was studied. Only diploids were detected in the G. conopsea cenopopulation occurred in the industrial zone of the NR. In this study we pointed on significance of genome size variation, which correlates with the adaptive evolution of the G. conopsea in West Siberia. The revealed absence of minor cytotypes (individuals with a higher level of ploidy) in G. conopsea population reduces intraspecific and intrapopulation diversity of the species.

Published: October 2021

The effect of three phyto modules – different combinations of indoor plants with the pronounced phytoncide activity – on the qualitative and quantitative composition of microflora in the air and on a decrease in the risk of acute respiratory diseases (ARD) in children was studied during autumn and winter in 2018-2020 in child care preschool institutions. Sanitary descriptive, epidemiological, sanitary bacteriological and statistical methods were involved. Observation revealed higher attendance rate in the observation group, in combination with lower recorded incidence of disease in comparison with the reference group. The fraction of facultative microflora (FM) with respect to the total microbial count (TMC) was about 30 % in the rooms equipped with phyto modules, while the ratio was 60% in the rooms without plants. The degree of antimicrobial activity depended on the assortment of plants and on the total leaf area per unit room volume. The phytoncide effect of the plants was traced to the most remote point of the room under investigation – 3 m. A favorable factor was an increase in the relative air humidity from 26 to 40%.

Published: October 2021

The leaves of C. sanguinea Pall. have the potential to accumulate dust on the surface. As the fine dust particles contain various chemical elements (ChEs), we studied the ChE composition in the leaves with different degrees of dust contamination to assess the impact on assay results. The samples of C. sanguinea leaves collected in the Kemerovo region (Russia) were divided into two groups based on the visual condition of plant material: clean leaves and dust contaminated leaves. The total ash assay revealed higher ash content, exceeding pharmacopoeial standards in the dust contaminated group. Dust contaminated leaf samples demonstrated significantly higher concentrations of many ChE: Si, Fe, Al, Na, Ti, Ni, Zr, Cr, V, Pb, La, Ga, Y, Sc and Yb comparing to non-contaminated plant material. The values of potentially hazardous ChEs were significantly lower than the maximum levels specified for medicinal raw materials in all studied samples.
Some special features of the water regime and the photosynthetic apparatus activity in Feijoa sellowiana (O. Berg) O. Berg plants under the water stress
Authors: Shishkina Elena , Gubanova Tatiyna , Titov Valerii
Published: October 2021

When assessing the drought tolerance of Feijoa sellowiana cultivars and forms, the total water content in leaf tissues and their waterretaining and regenerative capacity were determined, and the parameters of chlorophyll fluorescence induction were measured at different water content in leaves. Current-year leaves were characterized by a higher sensitivity to drought. According to the complex of water regime parameters and characteristics of the chlorophyll fluorescence induction (CFI), it was found that the cultivar Aromatnaya Fantazia and the form 3/1 are characterized by a relatively high drought tolerance. It has been demonstrated that the common method for assessing plant tolerance by the index of their water-retaining forces, in relation to Feijoa sellowiana genotypes, does not allow determining the critical level of water deficit. It has been found that in the cultivars and forms with low water stress tolerance, with the water loss of 20-25% from the leaf tissues complete hydration, irreversible irregularities in the PS II structures occurred. The most sensitive to the lack of water in the leaves were such parameters as variable fluorescence, rate constants of the photochemical and non-photochemical deactivation of the excitation, as well as the processes of Qa reduction in the reaction centers of PS II.
Vegetative Propagation of Deciduous Rhododendrons using Root Stimulating Agents
Authors: Smirnova Z.I. , Bondorina I.A.
Published: October 2021

The genus Rhododendron L. is the largest in the heather family Ericaceae DC. Rhododendrons are decorative evergreen, semi-evergreen and deciduous shrubs that have gained great popularity in green building, ornamental gardening and breeding. Among all groups of rhododendrons, deciduous are the most promising for cultivation in Central Russia due to their high winter hardiness, unpretentiousness and exceptional decorative effect. The article presents the results of experiments carried out at the GBS RAS in 2017-2020 on vegetative propagation of 50 species and varieties of deciduous rhododendrons. Vegetative propagation of deciduous rhododendrons is a rather laborious long process. Cutting deciduous rhododendrons has its own nuances and is considered problematic. In this regard, the selection of optimal conditions for the propagation of rhododendrons, which can enrich the cultural flora of the North-West, central Russia, the Urals and Siberia, was the main goal of this work.
Assessment of the impact of the urbanized territory of Yekaterinburg city on the formation of undergrowth in the forest park zone
Authors: Tolkach Olga , Dobrotvorskaya Olga
Published: October 2021

The parameters of the undergrowth in the forbs and berry groups of pine forest types in 9 parks in Yekaterinburg and areas of natural forest have been investigated. Data on the species composition, density, and distribution by groups of heights of plants that make up the undergrowth collected. It has been established that the transformation of the undergrowth by an urbanized environment neutralizes the influence of the growing conditions of the considered forest types on it. In the forest-park zone, an increase in the density of the undergrowth is observed in comparison with the natural forest. The specificity of the forest park undergrowth is the floristic contamination with adventive species, the number of which is close to 50% of the total number of undergrowth species. The coefficient of floristic similarity of the undergrowth, according to the Sorensen coefficient between forest parks and a site of natural forest, was 0.26-0.46. In quantitative terms, the self-seeding of adventive species in the undergrowth is less than that of native plants. The invasive activity of ash-leaved maple in city parks and its dynamics over a 10-year period are considered, using the example of one of the parks.

Published: October 2021

The aim of the work was to study the features of clonal micropropagation of essential oil rose interspecific hybrids obtained in embryo culture in vitro. Analysis of 12 crossing combinations demonstrated that the frequency of hybrid seedling formation in the embryo culture varied from 0 to 71.4%. For clonal micropropagation obtained in vitro seedlings were divided into stem segments with a node and cultivated on MS culture medium supplemented with 0.5 mg/l BAP and 0.1 mg/l GA3. During the multiplication of 13 hybrids (R. alba × R. damascena cv. ‘Kazanlykskaya’) in 2-6 subcultures, high variability of the multiplication index (1.8-18.5 depending on the genotype and passage) was revealed. This parameter was maximum in the 3-4th subcultures. The best ability to micropropagation showed hybrid No. 37-14. Microshoots were rooted in vitro on ½ MS medium, containing for different hybrids 0.5 or 1.0 mg/l NAA; frequency – up to 80.5-100.0%. However, in No. 37-2, 37-19 and 37-31 on four tested media, the number of shoots with roots was only 0-35.4%.

Published: October 2021

A method for detecting zones of soil contamination with contrast-in-resistivity ecotoxicants, as well as geophysical methods for monitoring soil decontamination processes, are discussed in the article. A zone of soil contamination was designed and simulated using electrical prospecting methods - sounding and profiling. The direct and inverse problem of electrical prospecting of a contaminated zone in the form of a sphere inside a homogeneous soil body was solved in this work, while the main design dependencies were determined, which most accurately describe the data obtained experimentally. The proposed algorithm, based on adaptive step size random search, allows to quickly determine the depth and the effective radius of a zone of contamination with contrast-in-resistivity ecotoxicants, based on the results of profiling, and to estimate the degree of pollution by the ratio of the resistivity of the anomalous zone to that of the host medium.

Published: October 2021

The possibility of using coal mining waste in mine concrete mixing is considered in the article. As a result of the research, scientific and practical results have been obtained that make it possible to evaluate the strength properties of mine concrete, depending on the content of coal dust particles - the waste of mining - in it. It has been experimentally proven that when a fine fraction of coal is added to mine concrete, the strength of concrete decreases at a certain ratio, but this strength is sufficient to ensure the required properties. As a result of the experiments, samples of concrete for mine construction were manufactured, into which a fine fraction of coal - coal dust - was added in various ratios. A series of mine concrete tests was carried out to determine its physical and mechanical properties; the optimal composition was determined, which provides process and strength performance of the mixture. The conclusions have been drawn about the quantitative content of a fine fraction of coal in mine concrete, which make it possible to maintain process performance of the mixture and the strength of structures.

As a result of anthropogenic destruction of natural biogeocenoses, a decrease in biodiversity occurs, leading to instability and degradation of both individual elements and the biosphere as a whole. In coal-mining regions, there are two equivalent environmental problems: land degradation as a result of mining and an increase in production and consumption waste. The unfavorable ecological situation affects the state of the ecosystem of the regions as a whole, which negatively affects the health of the population. In this regard, the development of predictive models of the state of disturbed lands - their reclamation and return to the national economic turnover - are relevant. The purpose of this work is to develop principles of rational nature management during land reclamation in the Kemerovo region, disturbed as a result of opencast mining of mineral deposits. The principles of rational use have been developed, their implementation will contribute to the improvement of the ecological situation. The mechanisms of implementation include: an integrated approach to solving the problems of land reclamation and disposal of solid household waste in a coal-mining region; forecasting and regulation of the introduction of alien objects; introduction of environmentally friendly technologies to minimize emissions of xenobiotics into the biosphere and decontamination of MSW processing products.

Authors: Kopytov Aleksandr , Kupriyanov Oleg , Manakov Yury , Kupriyanov Andrey
Published: October 2021

During the period of coal mining in Kuzbass, about 9 billion tons of coal were mined, which is 16% of all in-place reserves of coal in Kuzbass. In 2020, coal production amounted to 220.7 million tons, including 164.4 million tons of open pit mining, which is 74% of the total. The negative side of an increase in the share of open pit coal mining is an increase in the area of disturbed lands, which currently reaches 150 thousand hectares. To restore the biological diversity of dumps, a nature-like technology has been developed for revegetation of dumps, which consists in applying a 15 cm thick loam layer to the dump and introducing a grass seed mixture containing seeds of steppe plants. For six years, a stable, self-perpetuating permanent nature-like community is formed, numbering 30-40 species of steppe plants.
Selected aspects of the impact of the digital world on the training of personnel for the mining industry in the region
Authors: Panina Tatiana , Dochkin Sergey
Published: October 2021

The article considers the aspects of organizing targeted training of personnel for mining enterprises in the region in the context of its innovative development. Based on the analysis of various approaches to the diversification of the region’s economy, two main ones are identified: process and cluster, a reasonable combination of which can provide the required potential for innovative development of the coal industry and related sectors of the region’s economy. Special emphasis is placed on the training of personnel, without which it is impossible to introduce innovations in all key areas and at the main stages of the activities of coal companies. At the same time, globalization and the emergence of a new digital world and information society have created new perspectives in understanding the essence of adult education, which in the digital economy has its own characteristics, and new approaches are required to solve the problems of training personnel in a high-quality way. In these conditions, the education system appears as a network of active participants with a variety of educational practices, the presence of which is determined by personal and professional needs. It is necessary to ensure the transition from general, technological and algorithmic adult educational practices to unique and individual ones. The point of such a transition is not to discover new ones, but to select individual combinations of existing practices, strategies, and technologies. Individualized selection of sets of practices and educational strategies is becoming the dominant trend in adult education in the modern era. Practical implementation of the considered aspects will allow us to build the educational process in a different way and mutually beneficial interaction of organizations of additional professional education with consumers of educational services, which will ensure the practical implementation of models of harmonization and “economic rebranding” of the resource-intensive region, the creation of an institutional infrastructure for its harmonious development.
