While the microcrustacean composition in the Lena River Delta is well documented, the Tiksi settlement vicinity, nearby the Lena Delta, remains unexplored. This research focuses on characterizing copepod crustaceans in Tiksi's waters. The collected data enriches the microcrustacean distribution database in Arctic and Subarctic regions worldwide and facilitates an analysis of copepod faunal variation in northeastern Eurasia. A total of 64 copepod species were discovered near Tiksi, with 19 being newly identified for the region. Brackish water reservoirs and lakes demonstrated the greatest diversity within the fauna. The structure of copepod species complexes was consistent among water bodies of the same hydrological type. In brackish lagoons, bays, and lakes, species complexes exhibited intricate, multilevel functional and trophic structures. In contrast, rivers and streams displayed simplified complex structures. Around 20% of the examined fauna displayed East Asian-North American ranges, suggesting a connection to the ancient land of Beringia. Similarity among local Copepoda orders' faunas is linked to crustaceans' dispersal ability, with increasing similarity from Harpacticoida to Calanoida and Cyclopoida. Two distinct groups of regions with comparable faunas are recognized in northeastern Eurasia: European-Siberian, divided into European and Siberian branches, and Far Eastern. The potential existence of transitional zones between these groups is also discussed.</p> Aleksandr Novikov Ekaterina Abramova Anna Novichkova Elena Chertoprud Copyright (c) 2023 2023-09-27 2023-09-27 9 683–708 683–708 10.5281/zenodo.8373633 Diversity, stratigraphy and ecology of diatoms and plant pollen in the Miocene-Pliocene sediments of the Vitim Plateau (Baikal region, Russia) <p>We performed lithogeochemical and biostratigraphical studies of the core from the hole 8182 in the Northern paleovalley of Vitim Plateau. According to lithogeochemical characteristics of the sediments in the section, 5 members were found out. Three lower ones characterize the Dzhilinda suite, two upper ones – the Khoygot stratum. The analysis of biodiversity and fossil diatom algae distribution in the core resulted in revealing of 137 species and varieties of diatom algae related to 50 genera. Four diatom zones (DZ) were established by appearing or disappearing of index species. Ecological and geographic analysis showed domination of planktonic, indifferent, cosmopolite species. Palynological analysis revealed three pollen members with reconstruction of vegetation of forest type reflecting the vector of cooling and climate change from moderately warm one in Middle-Late Miocene to moderately cool in Early Pliocene.</p> Мarina Usoltseva Lyubov’ Titova Abdulmonem Hassan Svetlana Reshetova Еlena Rodionova Мarina Maslennikova Irina Chuvashova Sergei Rasskazov Copyright (c) 2023 2023-09-26 2023-09-26 9 643–682 643–682 10.5281/zenodo.8373408 Fauna and population of non-Passerine birds in the lower reaches of the Bolshaya Rechka River (Altai Territory, Bolsherechensky reserve) <p>The purpose of this paper is to provide additional information on the non-Passerine bird fauna and populations in the Bolsherechensky Nature Reserve, specifically within the Bolshaya Rechka River valley. Located in Altai Krai, the reserve occupies a typical territory of the Upper Ob forest massif. Protecting the habitats of rare and endangered bird species is one of the primary goals of the reserve. However, despite previous studies, our understanding of the avifauna and bird populations remains insufficient. To address this, we conducted bird surveys in the reserve during spring and summer of 2012, 2013, 2017, and 2021, specifically within the Bolshaya Rechka River valley. The results revealed that the summer breeding community of non-Passerine birds in the Bolsherechensky reserve consists of 48 species from 18 families and 12 orders. Additionally, we discovered 11 rare and endangered bird species previously unrecorded in the reserve. In particular, seven of these species lack specific distribution information in the latest regional Red Data Books, including the Black stork (<em>Ciconia nigra</em>), Oriental honey buzzard (<em>Pernis</em><em> ptilorhynchus</em>), Peregrine falcon (<em>Falco</em><em> peregrinus</em>), Red-footed falcon (<em>Falco vespertinus</em>), Common wood pigeon (<em>Columba palumbus</em>), Eurasian pygmy owl (<em>Glaucidium passerinum</em>), and European bee-eater (<em>Merops apiaster</em>). In general, our study significantly improves our knowledge of the non-Passerine bird fauna and population of non-Passerine birds in the lower reaches of the Bolshaya Rechka River within the Bolsherechensky Nature Reserve. The findings are valuable for the improvement of biodiversity protection measures.</p> Sergey V. Vazhov Alex V. Matsyura Viktor M. Vazhov Elena V.

In 2021, a male was recorded. We recorded several concurrent predatory species, like red fox, Pallas’s cat, wolverine, and brown bear, and prey species Altai marmots. The snow leopards performed visual and olfactory marking at their area. We concluded that snow leopards in this transboundary mountain area were active at temperatures up to 3°C in summer period.</p> Maksim R. Parkhomenko Tatyana V. Antonenko Alex V. Matsyura Sergey V.

Using one mitochondrial (<em>COI </em>barcode) and three nuclear (<em>Ca-ATPase</em>, <em>H3 </em>and <em>CAD </em>gene fragments) markers, we confirm its hybrid origin and demonstrate that this specimen is a hybrid between a female of <em>Colias christophi helialaica </em>and a male of <em>Colias cocandica cocandica</em>. Our study shows that an analysis of mitochondrial and nuclear molecular markers can successfully discriminate natural hybrids in such a taxonomically challenging group of butterflies as the genus <em>Colias</em>.</p> Nazar A.

In Russia, the species was previously noted in the south of its European part, Saratov and Kaliningrad regions. <em>Oxytropis pilosa</em>, a South Palearctic species, grows in central Europe, the European part of Russia, the Caucasus, Siberia, Mongolia, and Asia Minor. It is distributed in the steppe zone, insular steppes, forb and forb-grass steppes, and steppe meadows. A count of damaged <em>O. pilosa </em>seedlings was made and the percentage of fruit infection by seed-eating insects was calculated. The level of infestation in the <em>O. pilosa </em>fruits was 23%, and mass emergence of adults was observed in September. When examining leguminous plants for infection with seed-eating insects, a species of carpophage <em>Bruchidius marginalis </em>was identified, which is the first for the territory of the Republic of Khakassia.</p> Sofia V.

By species diversity at the subfamily level, the jewel beetles are distributed as follows: Julodinae – 1 species, Polycestinae – 5 species, Chrysochroinae - 14 species, Buprestinae – 14 species, Agrilinae – 22 species. At the genus level, <em>Agrilus </em>(15 species), <em>Sphenoptera </em>(9), <em>Acmaeoderella </em>(5), <em>Anthaxia </em>(5) and <em>Chrysobothris </em>(3) are the most abundant in the Zhetysu Alatau. The identified species of jewel beetles are confined to seven altitude belts and biotopes: the most populated is a shrub-steppe belt (25 species) followed by mountain-floodplain forests (14) and leaf-fir-forest belt (14), semidesert (11) and coniferous-forest (9) belts; medium-mountain mixedgrass belt (5) and subalpine meadows (2) demonstrate much poorer jewel beetle composition. Species of jewel beetles with known host plants are associated with arboreal and shrub plants from 21 families.</p> Aizhan M.

Microplastic pollution is the focus of interest worldwide due to its global distribution and adverse effects on living organisms. The largest number of studies addressing this issue explored the aquatic environment, yet terrestrial ecosystems also suffer from microplastic pollution. Insects are crucial for most terrestrial ecosystems. Few can compete with them in biomass productivity and species diversity, which makes them targets for studying the toxic bioaccumulation. This review article presents a systematic analysis of data on bioaccumulation, degradation of microplastics by aquatic and terrestrial entomofauna, and its ecotoxicological effects.</p> Mark Lee Anastasia V.

Horses have been shown to be hosts to 53 species of Nematoda, 5 species of Cestoda and 2 species of Trematoda. The prevalence of helminths ranges from 0.7% to 33.6% and the intensity of infection from 1 to 12,538 individuals. The article reveals the biocoenotic relationships between ungulates and their helminths established by trophic links and proves the character of formation of helminthofauna in ungulates under the influence of natural and anthropogenic factors in the Aral Sea region. Additionally, the seasonal and age dynamics of horse infection with parascaridosis and setariasis in Karakalpakstan is determined.</p> Amaniyaz J. Kaniyazov Erkinjon B.

The purpose of this research is to investigate the rice effect of the precooking process with sodium chloride and citric acid on the amounts of residual lead (Pb) and cadmium (Cd). In the current study, eight brands of high-consumption rice were used in the Arak-Iran market and their amounts of Pb and Cd were measured using graphite furnace atomic absorption spectrometry. Two rice brands, Pakistani Moeid and Indian 21, which contained the highest amounts of Pb and Cd, were selected and treated with soak (for 4h) and boiling (for 60 min) in 1% sodium chloride and 0.6% citric acid. The results showed that precooking Pakistani Moeid and Indian 21 rice samples with 1% NaCl reduced the amount of Pb by 15.7% and 16.2%, respectively. Furthermore, the amount of Cd was reduced by 10.5% and 10.8% for Pakistani Moeid and Indian 21, respectively. Furthermore, the results for precooking of Pakistani Moeid and Indian 21rice samples with 0.6 % citric acid showed a reduction in the amount of Pb by 9.3% and the amount of 8.9% and Cd by 11% and 9.6%, respectively. These numbers were in comparison with precooking rice with pure water. According to the results of this research, precooking rice samples with NaCl reduces the amount of Pb more effectively than that of Cd. Furthermore, precooking rice with citric acid reduces the amount of Pb and Cd by almost the same amount. In general, precooking rice with NaCl is more effective in reducing heavy metal contamination compared to citric acid.</p> Mohammad Reza Sangi Seyed Mehdi Talebi Mohaddeseh Hayatpour Alex Matsyura Copyright (c) 2023 2023-09-04 2023-09-04 9 529–538 529–538 10.5281/zenodo.8310970 Seasonal migrations of the Yellow Wagtail Motacilla flava (Aves, Passeriformes) according to results of the trapping and ringing data for sixty-four years in the Eastern Baltic <p>Based on the results of trapping and ringing Yellow Wagtail on the Courish (Curonian) Spit in Eastern Baltic in the amount of 3076 individuals during 1957–2020, the population numbers, the migration routes and wintering grounds are presented. The obtained seven recoveries of our rings account for only 0.23% of the efficiency of Yellow Wagtail ringing. The annual number of Yellow Wagtails captured varied widely over 64 years, from three to 206 individuals. The oscillations were wavelike in nature and showed different amplitudes. Of the seven birds with our rings found two birds in November and February were caught in the Federal Republic of Nigeria (West Africa), three birds during migration were found in Italy and two birds during the summer were found in Sweden and Finland. The length of the migration route from the Courish Spit to Nigeria was more than five thousand kilometers.

However, the taxonomic composition and structure of bottom invertebrates in low-mountain lakes of Altai remain unknown. Due to climate change and growing anthropogenic impact, studying the composition and structure of macrozoobenthos in these lakes is becoming increasingly urgent. In 2022, a study was conducted on macrozoobenthos from foothill lakes of the Russian Altai, specifically Kireevo in the Krasnogorsk region, Aya (Aiskoye) in the Altai region, Koksha and Svetloye in the Soviet region, Kolyvanskoye in the Zmeinogorsk region, and Beloye in the Kuryinsky region of Altai Krai. The study identified 152 species from 9 classes, including Turbellaria (1), Nematoda (1), Oligochaeta (17), Hirudinea (5), Bivalvia (2), Gastropoda (8), Arachnida (10), Crustacea (2), and Insecta (106). Of the insects, the order Diptera (69 species, including 59 chironomids) had the greatest species diversity. Additionally, the orders Trichoptera (16), Coleoptera (7), Ephemeroptera (5), Odonata (4), Heteroptera (4), and Megaloptera (1) were identified. Most of the studied lakes in the Russian Altai (Aya, Beloye, Kireevo, and Kolyvanskoye) had a taxonomic composition of macrozoobenthos similar to lowland lakes. Two lakes (Koksha and Svetloye) had a combination of features from both lowland and high-mountain lakes. The content of organic substances and their decomposition products in water, as well as substrate type, were the most significant factors determining the development of macroinvertebrate communities in the studied lakes.</p> Dmitry M.

The identification of <em>P. teletskoyensis </em>was based on the analysis of numerous scanning electron microscopy images since the beginning of a recent phytoplankton study in the lake. The investigation of the species revealed a wider variability of its qualitative morphological features such as valve relief, presence of granules on valve face, rimoportula position, and structure of alveoli. As a result, new data on the morphological variation of this species allowed for the refinement of its diagnosis. In addition, a comparison of the morphological features of <em>P. teletskoyensis </em>and other small-celled centric diatoms of <em>Pantocsekiella </em>and <em>Cyclotella </em>genera found in various water bodies across Europe, Asia, and America showed that <em>P. teletskoyensis </em>is most similar to <em>C. minuscula</em>, that was previously described from the deep-water Lake Ohrid located on the border of Northern Macedonia and Albania. We also conducted numerous measurements of <em>P. teletskoyensis </em>valve diameters, which enabled us to estimate the cell size in the population ranging from 3.02 up to 7.98 µm. The study of <em>teletskoyensis</em> population structure revealed that the group of 4.00-4.99 µm was consistently the most numerous among size groups with a step of 1 µm in all the months studied.</p> Sergei I.

The Red-breasted goose, which has a vulnerable status according to the Red List of the International Union for Conservation of Nature (IUCN), currently has a positive population trend. The Lesser white-fronted goose with the same status, on the contrary, is declining in numbers. Both species are under the scrutiny of geese specialists. To identify the possible nesting of these species, suitable steep banks of the Indik'yakha River were surveyed in the south of the Gydan Peninsula. In 2019, six nesting aggregations of Red-breasted goose were discovered with a total number of 11 pairs in association with Peregrine falcons. In 2021, only two nesting localities with three pairs of geese were found in the same area, and in 2022 three localities each with a pair of geese. In addition, in 2022, three nesting sites of Lesser white-fronted goose were registered, also with a pair of birds in each place. In one case, the Lesser white-fronted goose and the Red-breasted goose nested in one place together. The new findings of their nesting are the southernmost nesting sites in the south of the Gydan Peninsula, providing important information for their conservation management and monitoring needs to continue.</p> Igor G.

Sixteen key indicators of zooplankton structure, including abundance and biomass of major taxonomic groups such as Rotifera, Cladocera, Copepoda, and Anostraca, as well as individual stages of a life cycle and sex ratio in <em>Artemia </em>population, were studied in relation to 17 hydrophysical and hydrochemical indicators such as temperature, density, pH, total salinity, hardness, alkalinity, and other parameters. Monthly data for 2017–2020 and average annual data for 2000–2020 were analyzed to identify the impact of environmental factors on zooplankton structure. The study also examined the influence of these factors on the <em>Artemia </em>crustacean population, which dominates the zooplankton in this lake. The hydrophysical and hydrochemical regime of Lake Kulundinskoye can vary significantly from year to year, which affects the zooplankton indicators. Statistical analysis showed that monthly hydrophysical and hydrochemical data are more reliable than averaged data for the research period (April-October) in determining the impact of environmental factors on zooplankton structure. The results indicate that the changes in zooplankton structure are mainly due to the stimulating effect of increased salinity on the <em>Artemia </em>population and its depressing influence on other taxa. The long-term dynamics of zooplankton is characterized by a complex cyclicity of water salinity and productivity of the <em>Artemia </em>population, which is influenced by periodic changes in the moisture content of the lake catchment.</p> Lyubov’ V.

It has most strongly affected highly productive ecosystems, including those formed in river floodplains. Due to the initially high (background) values of NDVI, remote monitoring methods are not suitable for detecting changes in the biological productivity of floodplain vegetation. Research for both individual regions and landscapes is needed. However, for the floodplains of many rivers in Western Siberia, there are no primary descriptions of soils and vegetation. We have studied the soils and vegetation of the riverside floodplains in the lower reaches of the Taz River within the Pur–Taz interfluve. The studies were carried out within the hydrological continuum from the stream to the main Taz River. A regular change in soils and vegetation along the hydrological continuum was established, with fluvial processes intensifying. Ecosystems with the greatest diversity of plants, with thick layered soils such as Pantofluvic Fluvisol (Polyarenic, Polysiltic, Humic), are formed in the valleys of the tributaries of the Taz River on the natural riverside levee. The floodplain of the Taz River is distinguished by small differences in the heights of topographic elements, loamy soil texture, waterlogging and permafrost. The soils of the studied hydrological continuum were assigned to two Reference Soil Groups (Gleysol and Fluvisol). To describe the diversity of basic soil properties, six principal qualifiers and nine supplementary qualifiers were used. An assumption was made about the replacement of willow bushes by alder bushes during the warming period with the growth of some species of forbs (<em>Parasenecio hastatus</em>). The study made it possible to outline ways of further studying the floodplains of the Subarctic of Western Siberia.</p> Sergey V. Loiko Nina V. Klimova Ivan V. Kritckov Darya M. Kuzmina Sergey P.

Soil acidity, which in turn depends on LMW organic acids content, regulates the migration ability of compounds in landscapes and the bioavailability of nutrients. With an increase in the active layer thickness of peat soils in Western Siberia in the course of climate warming, new portions of LMW water-soluble organic compounds will enter, which will be quickly processed by microorganisms into CH4 and CO2. Five key sites were considered, located within thawed oligotrophic, frozen mound and polygonal bogs. The analysis of zonal patterns of acidity changes in the waters of peat soils indicates an increase in the pH in the series: northern taiga&lt;forest tundra&lt;southern tundra. A feature of the most acidic soils of the northern taiga is the high content of low molecular weight organic acids, the accumulation of which is determined by the species diversity of the vegetation cover and high humidity. The decrease in the content of acids in the soils of the southern tundra is due to changes in climatic conditions and, accordingly, the quality and quantity of organic material involved in the processes of mineralization and humification. Relationships between the pH of the soil solution and such parameters as the specific conductivity, the content of dissolved organic carbon, and the specific UV-absorbency (SUVA245) were revealed. Comparison of the acidity indices of peat soils of the zonal series of the European Northeast with similar ones obtained for the study area of Western Siberia showed that, at the same values of actual acidity, the exchangeable acidity values of peat soils of Western Siberia are slightly lower.</p> Tatiana V.

The spectrum of medicinal action of chicory includes antimicrobial, antiinflammatory, choleretic, diuretic, sedative, and appetite stimulating activities. Plant tissue and cell culture allow the production of high yields of plants, biomass, and valuable metabolites throughout the year. In our research, we produced aseptic plants from two Russian breeding (<em>Yaroslavsky </em>and <em>Petrovsky</em>), performed their primary phytochemical screening, and established the quantitative content of particular elements and substance groups using IR spectroscopy. It has been found that a high yield of viable aseptic plants of the <em>Yaroslavsky </em>cultivar can be achieved by seed treatment with 8% sodium hypochlorite for 10 minutes or 37% hydrogen peroxide for 5 minutes. For the <em>Petrovsky </em>cultivar, it is advisable to germinate nonsterile seeds and then introduce them into the culture by washing the seedlings in a slightly pink solution of potassium permanganate, followed by sterilization with 8% sodium hypochlorite for 5 minutes and washing with plants the antibiotic solution (0.8% gentamicin) for 15 minutes. All studied classes of compounds (tannins and phenols, flavonoids, saponins, alkaloids, glycosides, reducing sugars, and proteins) are present in aseptic plants of <em>C. intybus</em>; however, differences appear depending on the extractants (water and ethanol). IR spectroscopy has shown a higher content of moisture, fiber, and starch in seeds and a higher content of macronutrients, fat, ash, and proteins in aseptic plants.</p> Elizaveta P.

Being formed in a transitional climatic zone, on the southern front of the permafrost zone, these frozen peatlands may turn out to be highly reactive upon thawing and deliver high amounts of solutes to the hydrological network. A detailed study of a flat-mound bog was carried out in a key area of about 3 hectares (Purovsky district, Yamalo-Nenets Autonomous Okrug). The soil-ecological conditions of the site are described, as well as the effect of spatial heterogeneity on the composition and properties of soils. Using topographic mapping and photogrammetry, it was identified that the bog surface is characterized by distinct microtopography (mounds-hollows-thermokarst subsidence with a percentage areas ratio of 49:30:21, respectively). Small-scale variations in ecohydrological settings, microtopography, and vegetation affect the distribution of nutrients, organic carbon in soils, and DOC (dissolved organic carbon) in bog waters. The main soil types are Dystric Hemic Cryic Histosols and Dystric Hemic Histosols (Gelic) found on mounds and in subsidence, respectively. If the peat thickness decreases to 40– 60 cm, then Spodic Histic Turbic Cryosols (Albic, Arenic) and Histic Turbic Cryosols (Albic, Arenic) form. In hollows and fens, Dystric Epifibric Histosols, Spodic Histic Turbic Cryosols (Arenic), and Gleyic Histic Entic Podzols (Turbic) are the most common. The proportion of soils with frozen peat is no more than 20% of the area of the key site and permafrost lies deeper, in the underlying rocks. It was found that carbon stocks within the key area vary from 31.1 to 91.3 kg/m2. The maximum values are observed in transit subsidences/hollows between mounds, where water is discharged. Concentrations of macro-microelements in bog waters vary depending on microform types. For some elements (e.g., DOC, Fe, Al, B, Si, Ti, V, Rb, Sb, Cs, REEs (rare earth elements), Pb, Th, U), they are approximately equal or 1.5–2 higher on the mounds. The export of DOC and other elements in permafrost areas is primarily controlled by the residence time of water and movement ways along the profile. In addition to this, the physicochemical properties of peat and biomass, which are also higher on mounds, influence the distribution and accumulation of nutrients.</p> Tatiana V. Raudina Georgyi I.

Ach. and Cladonia arbuscula (Wallr.) Flot. <p>Lichens are symbiotic nature and produce unique secondary extracellular metabolites with high biological activity. In this paper, we compared the antioxidant and antimicrobial activity of two lichen species. Furthermore, we determined the quantitative content of antioxidants of low molecular weight and antimicrobial activity of 40% of the water ethyl extracts of <em>Cetraria islandica </em>and <em>Cladonia arbuscula </em>lichens depending on the layers’ treatment methods and the ratio of dilution of the dry extract with water. Live parts of dried lichens collected in an ecologically clean area of Yakutia were used for extraction. The antioxidant activity of the water-ethanol extract of lichens was performed using a spectrophotometric method. Antimicrobial activity was established using the discodiffusion method in agar in various dilutions of dry lichen extract. The highest antioxidants of low molecular weight were found in <em>Cetraria islandica </em>in distilled water with solid to solvent ratio of 1:1 and in the <em>Cladonia arbuscula </em>extract – in a ratio of 1:5. At the same time, preliminary mechanochemical processing of lichen layer raw materials from lichen layers (particle size up to 1 mm) was shown to increase the yield of low-molecular antioxidants by up to 50% compared to coarse grinding (particle size 2 mm). The antibacterial activity of the studied lichens was tested in <em>Staphylococcus aureus</em>, <em>Streptococcus pyogenes</em>, <em>Escherichia coli </em>by diluting the dry extract with water 1:1, 1:2, 1:3, 1:4, 1:5. The most significant antibacterial effect was found in the extract of the studied lichens in a 1:1 ratio. The diameter of the bacteriostatic zone in <em>Staphylococcus aureus</em>, <em>Streptococcus pyogenes </em>and <em>Escherichia coli </em>under the action of <em>Cetraria islandica </em>was 12±0.14 mm, 11±0.12 mm, and 12±0.13 mm, respectively. The suppression of the growth zone with <em>Cladonia arbuscula </em>against <em>Staphylococcus aureus</em>, <em>Streptococcus pyogenes</em>,&nbsp;<em>Escherichia coli </em>was 15±0.18 mm, 12±0.20 mm, and 13±0.20 mm in diameter, respectively.

The study covered the species composition, biotopic distribution and ecological features of water mites in different lentic ecosystems of the Nature Reserve. The research is based on 36 studied water bodies, which represented the main types of stagnant waters common on the Nature Reserve territory: lakes, floodplain ponds, temporary ponds and sphagnum bogs. The study revealed 51 species of Hydrachnidia and two species of Halacaroidea in different lentic water bodies. Most of the mites belonged to species typical of different types of stagnant and low flowing waters rich in submerged vegetation. Lakes of different types and permanent floodplain ponds were the richest in number of species and the number of mites. In these water bodies, three species of water mites prevailed, namely, <em>Limnesia koenikei </em>Piersig, 1894, <em>Piona pusilla </em>Neumann, 1875, and <em>Piona carnea </em>Koch, 1836. The number and species richness of mites were low in temporary ponds, but their fauna was based on specific spring species characteristic of astatic ponds.

The Carabidae list includes 81 species from 41 genera, 18 tribes and nine subfamilies. The ecological diversity of the ground beetle fauna is analyzed on three parts of the ridge. The greatest diversity of Carabidae is noted in the Karatepo Mountains (74 species), and the smallest in the Zirabulak-Ziyadin Mountains (54 species). The fauna of the ground beetles of the Chakalikalyan and Karatepa Mountains are closer to each other (Jaccard index – 0.79, Chekanovsky-Sørensen coefficient – 0.89). The lowest value of the similarity coefficients was noted between the Chakalikalyan and Zirabulak-Ziadin Mountains (0.64; 0.78). The most numerous are <em>Anchomenus dorsalis </em>(10.46%), <em>Calathus ambiguus </em>(8.23%), <em>Amara aenea </em>(7.48%) and <em>Harpalus rufipes </em>(6.03%).</p> Fazlitdin Khalimov Copyright (c) 2023 2023-03-14 2023-03-14 9 113–125 113–125 10.5281/zenodo.7725474 Taxonomic diversity and structure of phytoplankton in heterotypic lakes of Kulunda basin (Altai Krai) <p>In 2001–2021, the taxonomic composition and structure of phytoplankton in the heterotypic lakes of the Kulunda basin were studied. By the average and maximum depths and the way of salt accumulation, these lakes belong to deep-water brine, medium-deep brine, shallow-water brine, shallow-water self-sediment and drying up in summer period types of reservoirs. 241 species, 5 varieties and 3 forms of algae from 7 divisions, 17 classes, 7 subclasses, 44 orders, 78 families, and 130 genera were identified. The greatest taxonomic diversity was noted in the divisions Cyanobacteria, Chlorophyta, and Ochrophyta; the most classes (5) were in the division Ochrophyta; the most taxa with a rank above the family were in the subdivision Diatomeae (3 classes, 4 subclasses, 14 orders) and the division Chlorophyta (3 classes, 11 orders). In the spectrum of families, 12 ones (of 78) are leading with 34.6% of the total number of genera and 48.5% of the total number of species. The taxa spectrum is characterized by one-, two- and three-species families. The largest number of species in phytoplankton was found mostly in deep- and medium-deep lakes with a wide variety of biotopes both horizontally and vertically. The dependence of the number of species in the phytoplankton of the lakes on various environmental factors and features of the reservoirs (morphometric characteristics, water and air temperature, precipitation, salinity, pH, the Wolf number, some anions and cations) was analyzed. It was revealed that the correlation was higher for the smaller on area and volume water bodies, and less – for the larger and deeper ones.</p> Yulia N. Kosacheva Elena Yu. Mitrofanova Petr A.

The territory of the preserve is typical for the Verkhneobskiy forest area. One of the primary duties of the Nature Reserve is to protect the habitats of rare and endangered bird species. However, the modern avifauna in the reserve, despite several previous reports, remains underestimated and not sufficiently studied. Our work has been carried out over the spring and summer of 2012, 2013, 2017 and 2021. The number of species was estimated based on their density obtained during the survey, and a point scale was used to describe the species. We concluded that the summer (breeding) passerine bird populations of the Nature Reserve "Bolsherechensky" consist of 12 families and 35 species, while the presence of 15 rare bird species was registered in the Reserve. Our results will enrich the data bank on the fauna and the population of passerine birds of the lower reaches of the Bolshaya Rechka River in the Nature Reserve "Bolsherechensky", which can be used to improve biodiversity conservation measures.</p> Sergey V.

A methodology and an algorithm have been developed to conduct comprehensive studies using methods of taxonomy and plant ecology, phytochemistry, botanical geography, and resource studies. The developed algorithm has been implemented for large taxa of the family <em>Asteraceae </em>Dumort. 1820 from the flora of Southern Siberia (tribe <em>Cynareae </em>Lam. ex DC. 1813 and genus <em>Artemisia </em>L., 1753). Four groups of plants were identified, and recommendations on their use were elaborated. The group of promising species included 20 representatives of the tribe <em>Cynareae </em>(from the genera <em>Saussurea </em>DC. 1979, <em>Serratula </em>L. 1753, <em>Centaurea </em>L. 1753, <em>Cirsium </em>Mill. 1754) and 15 species of the genus <em>Artemisia</em>.

In sturgeon aquaculture, highest harm is caused by caviar saprolegniosis (byssus), a mycotic disease of caviar, which is characterized by damage through saprolegnium fungi during hatchery incubation. The main infectious agents are aquatic mold fungi of the genus <em>Saprolegnia </em>spp. A sample of water mold was isolated from infected eggs of a hybrid of Russian sturgeon (<em>Acipenser gueldenstaedtii</em>) with kaluga (<em>Huso dauricus</em>) with characteristic signs of the disease. Microscopic examination of an isolated oomycete revealed morphological features characteristic of <em>Saprolegnia </em>spp., but no oogonia or antheridia were found, which complicates further species identification. To identify the isolated pathogen, molecular tools such as PCR and sequencing of a DNA section including 18S rRNA, ITS1, 5.8S rRNA, ITS2 and 28S rRNA were used to distinguish between different species of aquatic molds. Analysis of the obtained nucleotide sequence showed more than 99% identity with the previously known DNA sequences of <em>S. parasitica</em>. According to the results of phylogenetic analysis, the obtained nucleotide sequence was in the same group with the known sequences of <em>S. parasitica </em>and separated from other species belonging to <em>S. ferax</em>, <em>S. diclina</em>, <em>S. delica</em>, and <em>S. australis</em>.</p> Ekaterina P.

In 2021 we conducted a forest pathology research of Khamar-Daban fir forests in south coast of Baikal Lake. The main aim was to inspect the territory for populations of this species. We found three localities with <em>P. proximus </em>on two out of four transects and based upon photo materials represented by stuff of the Baikal Nature Reserve revealed another locality inhabited by the species. The characteristics of <em>P. </em><em>proximus </em>populations such as occurrence, production, population density and the population growth rate in new localities were estimated. Since of our previous forest pathological inspection in 2014 it had spread eastward in Baikal region by at least 95 km. The highest site of <em>P. proximus </em>population was the slope of the valley of the Bolshoi Mamai River at an altitude of 1030 m above sea level. The estimated average speed of spread was about of 13-14 km per year. However, the most presumable invasion pathway of this species is the Trans-Siberian Railway. Thus, genetic analysis of sampled insects for the COI marker (mtDNA) revealed haplogroup I that previously was found as dominant variant in populations of Kemerovo and Tomsk Provinces. Despite the scattered distribution of <em>P. proximus&nbsp;</em>in Khamar-Daban fir forests the high population growth rate allows us to expect the formation of outbreaks during next decade.</p> Ivan Kerchev Roman Bykov Yury Ilinsky Copyright (c) 2023 2023-01-27 2023-01-27 9 1–11 1–11 10.5281/zenodo.7679805 Landscape diversity as an attraction basis in the design of tourist and recreational areas (the case of Bolshaya Belokurikha) <p>The article discusses the assessment of landscape diversity and biodiversity in a projected tourist-recreational territory. Bolshaya Belokurikha, located at the junction of the Altai plains and mountains, is used as a case study to illustrate the significance of these factors. The study area covers a 40 km section from Makaryevka to Krasny Gorodok villages, which attracts more than 250 thousand tourists annually due to its favorable climatic conditions and landscape diversity. The authors use modern methods, including mathematical modeling and spatial data analysis, to develop a GIS model of landscape diversity using the Shannon method of numerical entropy estimation. The model is presented as an isolinear map for cartographic visualization. The authors emphasize the importance of natural and ecological elements in the tourist frame of the projected area. They also propose considering landscape diversity as a stimulating factor for tourism development and as a basis for sustainable development of tourist territories in a two-level design, which includes the tourist-recreational complex and tourist area. To efficiently use the potential of the territory and ensure maximum preservation of existing landscapes, the authors suggest using constructed maps and GIS models of landscape diversity and biodiversity as a basis for functional zoning of the territory. This approach would help identify areas suitable for tourist development while also preserving the flora and fauna species diversity. Overall, the article provides a comprehensive approach to the sustainable development of tourist-recreational territories. By using modern methods and GIS models, the authors demonstrate how landscape diversity and biodiversity can be integrated into the planning and management of tourist areas, leading to a more sustainable and responsible approach to tourism development.</p> Alexander Dunets Evgeny Krupochkin Nadezhda Kurepina Olga Baryshnikova Natalia Yurochkina Copyright (c) 2022 Alexander Dunets, Evgeny Krupochkin, Nadezhda Kurepina, Olga Baryshnikova, Natalia Yurochkina 2022-12-31 2022-12-31 9 918 928 10.5281/zenodo.7686800 Above-ground phytomass and chemical composition dynamics of Stipeta Zalesskii phytocenosis in Ural-Ilek interfluves <p>We carried our investigationsin one of the typical phytocenosesof the Trans-Volga-Kazakhstan herb bunchgrass steppes underprotected regime conditions.

Nevski and petrophytous elementswere considered as a model. The dynamics of the above-ground phytomass stocks of this community was on the “Burtinskaya steppe” site in the Orenburg State Nature Reserve using thesquare sample cut method. The content of the main macroelements N, K, Na, Ca, P, and Mg is determined. The Federal State Budgetary Institution and the State Agrochemical Service Center “Orenburgsky” conducted the analysis of the plant samples.The resultsobtained were compared with the available literary data. Statistical analysis using the nonparametric Mann-Whitney U-test (α=0.05) in Statistica 6.1 revealed significant differences in the content of some macroelements between the drought year 2015 and the wet year 2016. The share of cereals (dominant community <em>Stipa zalesskii </em>Wilensky, codominant <em>S. lessingiana </em>Trin. &amp; Rupr.), both in living above-ground phytomass and in dead grass, have been prevailing. The following series of accumulation of elements: N&gt;K&gt;Na&gt;Ca&gt;P&gt;Mg was common for both fractures in most reference periods. The above-ground phytomass stocks in the examined community ranged from 335 g/m² to 404 g/m² in 2015 and from 525 g/m² to 678 g/m² in 2016. The findings obtained complement the available data for grasslands and pastures, present the opportunity to assess them comparatively with reference to standard and steppe zones, and serve as the foundation for further monitoring.</p> Neilya V.

Ex Willd that is found in extreme climatic conditions (Northern Pole of Cold) was researched by thinlayer and gas-liquid chromatography. This research aims to study the fatty acid profile of the perennial species <em>Dracocephalum palmatum </em>used as a medicinal herb in traditional medicine. We established that polyunsaturated fatty acids [FA], and more specifically linoleic and alpha-Linoleic acids, are prevalent in the lipidic constitution. The exceptional resilience of arctic and boreal plants is attributed to their flexible energy system that includes carbohydrates, proteins, and lipids. The latter are crucial in the energy balance of plants because they function as the main accumulator of spare energy and can create optimal conditions in cell membranes, unlike carbohydrates and proteins. Polyunsaturated fatty acids [PFA] present in the lipid layer allow the membranes to stay in the liquid state. Fat oxidation releases an amount of water that is considerably greater than that released by the combustion of carbohydrates and proteins. This research reveals that the fluidity of membranes in the arctic plant in question is optimal due to a high level of unsaturated lipids. The high amount of unsaturated FA in <em>Dracocephalum palmatum </em>lipids is attributed to the plant adapting to its poor growing conditions. We assume that late flowering plants with a higher than average level of PFA (linoleic and linolenic acids) higher than average play an important role in the conservation of reaction energy resources of animals in the northern environment.</p> Vasiliy V.

Time series analysis is used to identify the structure of dynamic series and their prediction. The demographic characteristics of zooplankton are well suited to analyze seasonal and interannual changes in ecosystems. Since the dynamics of species richness and river flow are often interdependent, we studied zooplankton biodiversity in the upper reaches of the Ob River in relation to the phases of the water regime. A six-year sampling of zooplankton was performed from surface water from the Ob River at two stations near the city of Barnaul. In total, 203 species and forms of zooplankton were detected. In all phases of the water cycle, Rotifera dominated in species number. To analyze the species diversity of zooplankton, we used 20 indices, of which 10 were not random on both coasts and could be used in monitoring. The species diversity of zooplankton in a sample, according to Margalef and Menhinick indices, was the highest during the recession of the second flood wave. The generalized measures of diversity (Williams polydominance and Shannon indices, and Fischer alpha) showed their maximum during the recession of the second wave of high water and in the summer low water period. Statistically significant declines in trends of some species diversity are evidence of small changes in the structure of the zooplankton. Time series analysis in the assessment of community biodiversity helps to select indices suitable for predicting ecosystem state, as well as to identify related changes in the community.</p> Olga Burmistrova Copyright (c) 2022 2022-12-30 2022-12-30 9 887–901 887–901 10.5281/zenodo.7729018 Sulfur content in needles of cedar (Pinus sibirica Du Tour) and siberian fir (Abies sibirica Ledeb.) of the Southern Baikal Region: Influence of industrial emissions <p>The paper presents the results of studying the sulfur content in the needles of cedar and Siberian fir of the Southern Baikal Region, carried out in the 2014–2015 period. The research aims to determine whether Baikal Pulp and Paper Mill (BPPM) are the primary stress factor of abiotic nature, which leads to the degradation of cedar and Siberian fir stands in the Southern Baikal Region. The authors have determined that the primary factor is the long-term impact of the emission of pollutants from heat power companies in the Irkutsk Region, as indicated by numerous studies using mathematical modeling methods. The research demonstrates that the assimilation organs of the cedar are more sensitive to the effects of sulfur dioxide compared to the needles of Siberian fir. Therefore, cedar needles can be considered as a more sensitive indicator of atmospheric pollution with sulfur dioxide. The authors have established that the primary source of contamination of Siberian fir needles is the SO₂ emission from the heat and power enterprises of the Irkutsk Region and not the emission of sulfur-containing compounds of the BPPM. The authors found that in the period from 2010 to 2019, the total SO₂ emissions from large industrial companies were an order of magnitude lower than the volumes of SO₂ emissions from heat power companies in the Irkutsk Region. These emissions will provoke a further deterioration in the state of the boreal forests of the Southern Baikal Region.</p> Ludmila V. Kanitskaya Olga I. Gorbunova Olga A.

Therefore, we used population research, morphometric, and physiological methods in this research. In addition, we studied the morphophysiological heterogeneity of the natural populations of <em>Bupleurum aureum</em>, the dynamics of the population size over three years in the forests of various natural zones of the Republic of Tatarstan. For all cenopopulations, a proportional contribution of aboveground biomass to the achievement of the generative sphere can be observed, even with a significant deterioration in the growth of particular plants. We noted a decrease in plant size in low illuminated and nitrogen-poor soils (1 CP). However, plants had the best indicators of raw material quality, flavonoids content in terms of rutin, as well as soluble phenolic compounds. Powerful plants were formed under optimal conditions in deciduous forests of the forest-steppe zone, but the content of flavonoids in all parts of the plants was insignificant. However, for plants in this natural zone, a higher content of tannins was recorded. Within the republic, the species was sufficiently stable, had high plasticity, and was self-renewable. However, this species needs to be preserved, so collection of its raw materials is not recommended due to the small area of forest within which <em>Bupleurum </em>grows.&nbsp;We suggested creating artificial plantings of this species with the recreation of conditions that ensure the synthesis and accumulation of various groups of phenolic compounds.</p> Olga A.

The scale of light pollution is increasing yearly and is negatively affecting the functioning of terrestrial and aquatic ecosystems. Of the aquatic ecosystems, marine ecosystems are the most studied, while there is very little information on the effect of artificial lighting on freshwater ecosystems. Among freshwater aquatic organisms, there are relatively little data on the effect of artificial light on crustaceans and fish, while we could find no meaningful data on the effect of artificial light on molluscs are practically absent. Here we test whether different types of artificial lighting, differing in their spectra, affect the activity of the Holarctic mollusc <em>Radix auricularia</em>. For this, we used two light sources (with warm and cold light) and a 1-m long aquarium. We found that both light sources affect individuals of this species, but the effects of this exposure are different. Artificial lighting (depending on the spectral characteristics) can increase the activity of molluscs of this species or reduce it. In the long term, the impact on the ecosystem will depend on the type of water body where light pollution is present, where individuals of this species live, and the type of light sources.</p> Dmitry Yu.

They should also be unpretentious in terms of housing, consumption of cheap and suitable feed which provides a satisfactory increase in biomass and contains necessary nutrients in the required ratio. Several local species of terrestrial molluscs and insects fit these criteria and have been were selected as model species, such as the yellow slug <em>Limacus flavus </em>(Linnaeus, 1758) which has been studied in detail. Individuals of this slug were collected from a subterranean vegetable store in the city of Novosibirsk, and reared for 5 months under laboratory conditions with different lighting, humidity and temperature. Standard vegetables for winter storage, carrot, cabbage and potato (the preferred ingredient), were provided to the slugs. The most effective factors for the development of body weight and size of the slugs were registered in the dark under moderate humidity and temperature. Average weight and length of slugs at the beginning of the experiment in March 2022 were 0.62 gram and 3.42 mm, and at the end of the experiment in August 2022 were 3.67 gram and 5.76 mm (respectively x 5.9 and x 1.7). Therefore, basement and underground cold premises lacking constant lighting and provided with potato waste as a feeding substrate appear to be optimal for raising and rearing this slug species; naturally this would be of particular interest for food production in regions with cold climate conditions.</p> Sergei E.

Further development of agriculture without taking into account changing climatic and environmental factors increases risks both for steppe ecosystems and for the sustainability of agriculture. The field production of the agro-climatic zones of the Altai Territory is characterized by the high variability of gross yields associated with the dynamics of precipitation, air temperature, and soil fertility. Under the current conditions, the analysis of the temporal and spatial dynamics of bioclimatic potential is of high practical importance for the development and implementation of adaptive agricultural technologies. A retrospective analysis was carried out and a modern bio-climatic characteristic of model territories representing various agroecological zones was compiled for this purpose. The object of research was data on average daily, average monthly, and average annual air temperatures, the level of precipitation, the water vapor pressure, and relative humidity. Statistical processing of analytical data was carried out in Excel. Calculations revealed significant temporal and spatial dynamics of the BCP. Spatially, it is characterized by a significant decrease in a north-western orientation. The lowest average values, 1.71-1.81 units, were observed in the Kulunda and Rubtsovskaya agroecological zones, with a coefficient of variation of more than 20.0%. The Zarinskaya and Aleyskaya agroecological zones were characterized by the highest values of BCP, and the Predgornaya zone presented maximum values of BCP, at the level of 2.70 units with high stability. Temporally, the BCP of the Zarinskaya, Kulunda, and Priobskaya agroclimatic zones is characterized by a negative trend; in other zones, its almost zero balance is noted. A sufficiently expressed difference in the BCP of various agroecological zones has an impact on the realization of the biological potential of cultivated crops. Analysis of the level of development of the vegetative mass of spring wheat by determining NDVI confirmed this assumption. For a systematic assessment of the influence of climatic and anthropogenic factors on the production process of field crops and the development of measures for the rational use of agricultural landscapes, it is advisable to determine the potential yield according to the BCP, determine the degree of its implementation in the economic harvest and justify techniques for leveling limiting factors in agrotechnology of individual agroecological zones.</p> Yuriy A.

For the period 2001-2021 there is a pronounced trend for increasing yields in almost all crops. The exception includes only permanent grasses for green feed which is explained by aridization of the climate and the established agrotechnology in recent decades. Data analysis shows that planting acreages have decreased for such crops as spring wheat (from 107.3 thousand ha in 2001 to 59.7 thousand ha in 2021), oat (from 8.6 thousand ha in 2001 to 6.2 thousand ha in 2021) and permanent grasses (from 15.4 thousand ha in 2001 to 4.8 thousand ha in 2021). When estimating the monitoring areas with agrocenoses on the water index calculated using Sentinel-2 data it was identified that for sainfoin, linen, sunflower, lucerne and corn the range of NDWI values ranged from -0.2 to 0.4. Whereas they were drought tolerant crops, stress was insignificant. Hayland haylages as forage lands did not have any negative index values. For oat and soy, the index indicators were lower, the values ranged from -0.2 to 0.25. A value range for wheat varied from -0.2 to 0.3. Buckwheat was rich in phytomass and the NDWI value range was from -0.1 to 0.45. That gave evidence of the sufficient water availability of the crop. Agrocenoses productivity depended on the level of the area moistening and the soil and climate conditions were fairly homogeneous on the selected territories as correlation between ARVI and NDWI values was 0.9. According to the satellite data the most productive ones were oat crops with sainfoin and buckwheat.</p> Natalia V. Ovcharova Marina M. Silantieva Elena Yu. Zhukova Ludmila V. Sokolova Natalia V.

I. Mesomorphic species <p>Section <em>Stenopoa</em> Dumort. is one of the largest representatives of the bluegrass genus (<em>Poa </em>L.). Despite relative antiquity, <em>P. palustris </em>L. and <em>P. nemoralis </em>L. have not been perserved in original states. Their ongoing evolution and hybridization has increased their diversity and has complicated the system. This obligate to search for new morphological characters, suitable for taxa discrimination, as well as for phylogenetic relationships. It is well known, that studying of grasses is difficult, bluegrass in particular. The reasons for this are next: their vegetative and reproductive organs structure is extremely uniform; the number of characters used in taxonomy is small as well as the number of these characters states. Meanwhile, characters of epidermis structure are widely used in the systematics and diagnostics of grasses. These characters consist of a presence or an absence of pubescence along the veins, lower lemmas keel and callus, and an rachilla. The main goal of the current work is to assess the variability of epidermis sculptural features, that determine the degree of stems and sheaths roughness of mesomorphic bluegrasses in <em>Stenopoa </em>section; and to assess the possibility of using these characters in taxonomy. Anatomical surfaces' study of stems and lower leaf sheaths was carried out with a Biolam-1 binocular light microscope (Russia) and a SEC SNE-4500M (SEM) scanning electron microscope (South Korea). Studies of diversity of stem and leaf epidermis structure on mass and serial herbarium materials showed that the change in the roughness degree has partly continual, partly discrete character. Sculptural formations are represented by a variety of crown cells, pricles, and bristles, that in fact are short stiff hairs. Thus, the characters of epidermis structure cannot be used as discriminators for mesomorphic bluegrasses of the <em>Stenopoa </em>section. These characters can act as additional ones and mark the evolutionary branches of <em>P. palustris </em>and <em>P. nemoralis </em>along with such morphological features as the length of the ligule and the rachilla pubescence.</p> Marina V.

(Poaceae). II. Xeromorphic species <p>Section <em>Stenopoa </em>is one of the most significant among the bluegrasses, and its proper identifying is important task. The epidermal characters, which determine the degree of roughness of the bluegrasses, are used widely in botanical literature, but the information on bluegrasses characters is controversial frequently. This work is devoted to the study of xeromorphic representatives of the section. The aim of this work was to assess the variability of the sculptural features of the epidermis, which determine the degree of roughness of the stems within xeromorphic bluegrass of the <em>Stenopoa </em>section, and the possibility of using these characters in taxonomy. The types of epidermal trychomes and their variability and frequencies within the populations of 12 species were researched using SEM and light microscope. As a result of the study, no species-specific types of epidermal structure were revealed. In all the studied species, with the exception of the Central Asian hybridogenic species <em>Poa psilolepis</em>, the epidermis of the stem and leaf sheaths contained crown cells and pricles or bristles in varying proportions. Under the panicle only crown cells or pricles directed upwards were observed. The most species showed high interpopulation and intrapopulation variability. At the same time, the Central Asian species were distinguished by less polymorphism and a small number of deviated individuals in the populations. The conducted studies cast doubt on the possibility of widespread use of epidermal sculpture as a discriminator for xeromorphic <em>Stenopoa </em>species, including for distinguishing between the Siberian <em>P. stepposa </em>and the European <em>P. erythropoda</em>.</p> Marina V.

The Herbarium ALTB (Barnaul) served as the empirical basis for the current study, and it is the largest plants collection from transboundary territory of the AMC and the main material of the "Flora Altaica" project. Thanks to the Herbarium ALTB digitizing, it becomes possible to identify endemics of the AMC transboundary territory and to establish the specificity of the flora without government and language barriers.

Low-mountain and lowland lakes have a similar zoobenthos structure. With height, the taxonomic structure becomes more complicated, and the dominant taxa of macroinvertebrates change. The peculiar feature of bottom zoocenoses in mid- and high-altitude lakes is high frequency of occurrence and large contribution to the total biomass of crustaceans of the family Gammaridae. We described the trophic structure of zoobenthos and identified five main trophic groups. In terms of species number, the collector-detritus feeder and predator groups dominated in the trophic structure of all lakes.

To assess the features of aquatic ecosystems that function in waterfall streams, macroinvertebrate communities of the Tevenek River (Lake Teletskoye basin, Northeastern Altai) were examined above and below the waterfall. The diversity, abundance, and biomass of macroinvertebrates were higher above than below the barriers. <em>Gammarus korbuensis </em>showed the most significant decrease in number (from 3.1 to 2.3 thousand ind./m2) probably due to the intensive use of amphipods as food for fish living in Lake Teletskoye. An additional factor in favor of the high species richness of macroinvertebrates in the upper reaches is the geomorphology of the waterfall river valley that contributes to the formation of more diverse conditions above the waterfalls. Hydrobiological studies of waterfall streams can help to understand the restructuring of benthic communities divided as a result of the human impact.</p> Liubov V. Yanygina Petr A.

Transmission electron microscopy allowed us to investigate the species diversity of scaled chrysophytes in 14 Arctic water bodies near the town of Tiksi (Yakutia) relative to hydrochemical gradients. We described a high species richness of scaled chrysophytes, 65 species from 6 genera: <em>Chrysosphaerella</em> (2), <em>Paraphysomonas </em>(8), <em>Lepidochromonas </em>(3), <em>Spiniferomonas</em> (10), <em>Mallomonas</em> (23), <em>Synura</em> (19). The water bodies we studied had a significantly different species composition. The composition of the species in the study area was confirmed to be affected by concentrations of water dissolved oxygen (O<sub>2</sub>), ion nitrate (NO<sub>3</sub><sup>-</sup>) and copper ion (Cu<sub>2</sub><sup>+</sup>) as well as by indicators of biological and chemical oxygen demand (BOD and COD). The species richness (α richness) is proved to be higher within creasing concentrations of COD and O2, while increasing concentrations of copper ions (Cu2 +) in water led to its reduction. According to ecological and biogeographic data, ubiquitous and cosmopolitan species prevailed in the longitudinal group of the study area (60 %), while polyzonal species (55 %) predominated in the latitudinal group. A high share of Arctic boreal species (19 %) and the presence of typically boreal species (11 %) were identified in the latitudinal group. A biogeographical distribution of scaled chrysophytes typical of Arctic water bodies in contemporary conditions that reflect global warming trends was described. <strong>&nbsp;</strong></p> Anna Bessudova Viktor Gabyshev Yurij Bukin Olga Gabysheva Yelena V.

On the territories of forestries, the areas for detecting fires, the areas for eliminating fires, the type of territories covered and the causes of occurrence are determined. The peaks of fire activity in the forest areas for a ten-year period were determined. In total, during the study period, 569 landscape fires were registered on the territory of three forestries, the total area of detection was 3369.36 ha, the total area of liquidation was 6793.74 ha. The areas most prone to fires are directly forested 84.49% and non-forested 11.48%. A comparison was made of the territories of the Timiryazevsky forest district, where fires took place over the period 2012–2021, as well as the territories where artificial reforestation was carried out over the same time period. The dependence of artificial reforestation measures on the frequency of fires in forestry areas was revealed.</p> <p>&nbsp;</p> Vladislav V. Perminov Denis P.

In contrast, the greater wax moth <em>Galleria mellonella </em>(Linnaeus, 1758) and the gypsy moth <em>Lymantria dispar </em>(Linnaeus, 1758) are referred to as resistant hosts, slightly susceptible to this microparasite. The goal of the present study was to test <em>N. pyrausta </em>against a broad range of lepidopteran species with different taxonomy, physiology, and ecology. The susceptibility to <em>N. pyrausta </em>spores fluctuated greatly among members of various families and superfamilies of Lepidoptera. As many as 13 species tested were found to be refractory (not able to support the development of the microsporidium), including three species of Yponomeutoidea, four species of Papilionoidea, one species of Pyraloidea, two species of Bombycoidea, and three species of Noctuoidea. The species found to be susceptible (with a high proportion of specimens displaying developed infection) included: <em>Evergestis forficalis </em>(Linnaeus, 1758) (Crambidae), <em>Aglais urticae </em>(Linnaeus, 1758) (Nymphalidae), and <em>Dendrolimus sibiricus </em>Chetverikov, 1908 (Lasiocampidae). The species newly found to be highly susceptible (high proportion of infected insects accompanied with high levels of&nbsp;early mortality) were: <em>Spodoptera exigua </em>(Hübner, 1808) (Noctuidae) and <em>Aglais io </em>(Linnaeus, 1758). Large quantities of spores can be produced in vivo using substitute laboratory host <em>A. urticae</em>. These results confirm previous observations that physiological host range of microsporidia (observed under experimental conditions) is broader than the ecological one (observed in nature).</p> Yuri S.

The species demonstrates high phenotypic diversity when it inhabits various types of water bodies. Here, we investigate whether there is a relationship between the genetic variability and phenotypic diversity in natural perch populations. <em>Perca fluviatilis </em>samples (<em>n </em>= 218) were collected from seven localities in the Ob-Irtysh river basin in western Siberia, Russia. We used color morphs and standard morphometric approach to study phenotypic diversity, allozyme and ISSR-PCR markers to study the genetic variability of the perch. In total, 19 types of perch colouration were found. The number of color morphs varied from 4 to 16 in different reservoirs. The sets of colour morphs and prevailing coloration types, as well as some morphometric characteristics, were significantly different in all studied populations. Low allozyme variability was identified in the perch. The average observed and expected allozyme heterozygosity was 0.003 and 0.056, respectively; 13% of the loci were polymorphic. The genetic diversity (<em>h</em>) of the markers (ISSR) was 0.31; from 53% to 96% of the bands were polymorphic. Genetic differentiation in the perch was high, especially in allozyme loci. The FST and GST values were 0.39 and 0.085 for allozyme and ISSR markers, respectively. The genetic variability indices of the perch did not correlate with phenotypic diversity. Our results suggest that the use of different phenotypic or genetic markers can provide extremely different information on the level of variability in the population.</p> <p>&nbsp;</p> Oxana N.

Further, the paper evaluated the influence of seeding quantities, component ratios, and weather conditions on yield and reaction in agrophytocenosis. Field tests and results processing complied with the appropriate methods. The paper examined weather conditions, quality of grain forage, yield, land equivalent ratio, competitiveness, and aggressivity of crops. Land equivalent ratio (LER) reached 1.41 to 1.77 when planting mixed legume grains at seeding quantity of 0.9 to 1.4 germinating seeds per hectare, where vetch amounts to 32%–42% of lupine content (0.38–0.45). The research demonstrated the resilience of crops to lodging and their suitability for thrashing. Under favorable humidification (Selyaninov hydrothermal coefficient (SCC) at 1.6), narrowleaf lupine grains constitute the bulk of the yield (65%), while at less favorable humidification (SCC 0.62), spring vetch generates most of the yield (80%). Neither crop demonstrates a significant advantage under moderately arid conditions. under unfavorable weather conditions, the competitiveness of vetch (CRba) relative to lupine elevates from 1.8 to 7.3, while its aggressiveness (CAba) decreases from 4.9 to 1.6. This suggests that there is positive alleopathy and environmental tolerance in lupine and vetch agrophytocenosis. The research demonstrated the possibility of efficiently growing spring vetch and narrowleaf lupin in mixed crops in the Middle Urals to produce high-protein grain concentrate. Further, the research established the optimal seeding quantity and component ratio and evaluated the influence of weather conditions on yield and changes in the proportion of harvested crops.</p> Andrey V.

(Asteraceae) <p><em>Cousinia pterocaulos </em>(C.A. Mey.) Rech. f., is an endemic species of the Asteraceae family in Iran and Transcaucasia, which is naturally distributed in northern regions of Iran. In the current study, we evaluated the composition of essential oil, total flavonoids and phenolic compounds, and free radical scavenging activity of <em>C. pterocaulos </em>extract. Plant materials were collected from a natural population of<em> C. pterocaulos</em> in Mazandaran, and identified based on description provided in Flora Iranica. Essential oil from aerial parts of this plant was extracted using Cleavinger type apparatus and analyzed its composition using GC and GC/MS apparatus. Moreover, the methanolic extracts from aerial parts were used to determine its total flavonoid and phenolic compounds and also capacity in scavenging the stable DPPH free radicals. The results indicated that total phenolic and flavonoids contents in this species is relatively small compared with other <em>Cousinia</em> species. Meanwhile, its capacity in scavenging free radicals is relatively higher than other species that were reported in previous studies. Furthermore, the main essential oil composition was 4,6-Heptadiyn-3-one (43.8%), which has not been detected in other <em>Cousinia</em> species. These findings revealed that each <em>Cousinia </em>species has a specific phytochemical property, leading to a unique biological activity.&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;</p> Samira Hazrati Ebrahim Salimi-Sabour Faraz Mojab Seyed Mehdi Talebi Alex Matsyura Copyright (c) 2022 2022-07-20 2022-07-20 9 175 184 10.5281/zenodo.7686835 Diversity of helminth fauna in teleost fish within the Tver region <p>Helminths affect multicellular animals of all types except echinoderms and sponges. In particular, within Volga reservoirs, the infestation of commercial fish by Pseudophyllidea larvae, <em>Opisthorchis felineus </em>(Rivolta, 1884) metacercaria, and other parasitic worms has increased significantly. This poses a threat of growing infestations in humans. The Vazuz Reservoir is a part of the large Vazuz hydrotechnical system connected with the Moscow River and is actively used for water supply to the Western and Southwestern districts of the capital. The investigated impounding reservoir is located on the border of the Tver, Moscow and Smolensk Regions. Most of the population in these regions actively promotes fishing as a hobby. Helminth fauna monitoring is relevant due to the active catch fish consumption by the population. The purpose of this study was to assess epizootic helminthiasis within the Zubtsovsky District of the Tver Region due to the special activity of using the Vazuz Reservoir by professional and amateur fishers. The objects of the study were three commercial fish species widely represented in this water area: river perch <em>Perca fluviatilis </em>Linnaeus, 1758, common roach <em>Rutilus rutilus </em>(Linnaeus, 1758), and common bream <em>Abramis brama </em>Linnaeus, 1758. The fish were caught at two points of the Vazuz Reservoir right branch and frozen for further study in the laboratory of the Zoology Department of the Russian State Agrarian University – Moscow Timiryazev Agricultural Academy. An incomplete helminthological dissection revealed representatives of the flatworm type at various stages of development, which were subsequently identified. The fish in the carp family, namely <em>Abramis brama</em>, had the highest prevalence in percentage terms.</p> Lyudmila S. Drozdova Georgy M. Shemyakin Fyodor A.

The study of <em>Osmorhiza aristata </em>population was carried out during three growing seasons of 2019–2021. The phytocoenotic relationship in the conditions of habitats in Siberia, morphological characters, and origin were determined, which make it possible to suggest the natural origin of the species in the territory of the hemiboreal lowland forests in the south of Western Siberia. We determined the species composition of the forest communities in the areas of <em>Osmorhiza aristata </em>growth. In these communities, the number of higher vascular plants totals 30 species. The habitat characteristics of <em>Osmorhiza aristata </em>in the ribbon pine forests were identified. The species under consideration is included in the Red Data Book of Altai Krai (2016), the Red Data Book of the Altai Republic (2007), the Red Data Book of Kuzbass (2021), as well as in the Red Data Book of the Russian Federation (2008).

Macrobenthos is one of the essential components that determines the normal functioning of the marine ecosystem. We studied the composition, structure, and quantitative characteristics of macrobenthos and their functions. We grouped all coastal zones into four groups: (1) open areas subject to the influence of the prevailing river flow and minimal impact of the marine fleet; (2) open areas of the north-eastern and northern coasts, where the accumulation of organic matter (OM) is not observed; (3) water areas with naturally elevated OM content and local anthropogenic impact; and (4) the most polluted territories, subject to the intense chronic influence of factors of accumulation of OM, mainly of anthropogenic origin. The Golden Horn Bight is the water area subjected to the most significant anthropogenic impact, while the Kievka, Udobnaya, and Rudnaya Bights, on the eastern coast of Primorsky Krai, are the areas with the smallest level of anthropogenic press. The water areas of Nakhodka, Vladimira, Vostok, and Troitca Bight, enriched in organic matter, occupied the intermediate position. We revealed that the most significant components of macrobenthos-macrophytes and bivalves-cease to work as an effective biological filter, and the transformation of incoming pollution in the water area is too slow in conditions of chronic pollution of coastal marine ecosystems. The heterotrophic community feeds on a significant amount of introduced organic matter, often of toxic origin, the nature of which probably affects the functioning of mass groups of organisms, reducing the indicators of biodiversity and abundance.</p> Yulia A.

However, the quantitative content of biologically active substances in plant cells is insignificant and the currently available extraction methods do not allow for the complete extraction of biologically active substances as a result of the strong lignocellulose matrix of the cell. Therefore, it is necessary to look for new extraction methods that increase the yield of extractive substances from plant raw materials. This paper is devoted to the effect of supercritical fluid extraction on the quantitative content of extractives contained in a plant cell. The study aims to establish the effect of supercritical fluid extraction on the lignocellulose matrix and the yield of extractive substances. The plant biomass of the vegetative part of the narrow-leaved cypress (<em>Chamaenerion angustifolium </em>L., Scop., 1771); roots and rhizomes of the stinky bug (<em>Actaea cimicifuga </em>Schipcz., J Compton); roots and rhizomes of the golden root (<em>Rhodiola rosea </em>L., 1753) were used as research objects. The extractive substances were extracted by sequential liquid extraction, supercritical fluid extraction, and a combination of these methods. To extract the maximum amount of extractives, the following solvents were used: a nonpolar solvent (hexane, 70% ethanol) and a highly polar solvent (water). Extraction of plant materials with supercritical CO₂ was carried out in a SFEU-5/2 laboratory setup with the following parameters: pressure (P), 350 bar; temperature (T), 60 °C; extraction time (t), 180 min. The comparison of the yield of extractive substances obtained by sequential liquid extraction and aqueous alcoholic extraction with the preliminary processing of raw materials with supercritical CO₂ shows that treatment with supercritical carbon dioxide activates the plant matrix; therefore, the content of the extracted components increases.</p> Alexandra V.
