The paper deals with the study of burdock blossoms (Asteraceae : Arctium ) in the Yelabuga District of the Republic of Tatarstan where they are one of the most common species among the Compositae plants. They are mostly ruderal weeds, growing usually in waste places (abandoned orchards, wastelands, ravines, roadsides, river banks, dumps, walls of houses and fences, etc.). Some representatives of this genus are also found in the floodplain forests, sparse deciduous forests, clearings, forest edges. The paper presents some results of study of species composition and population structure of phytophagous insects, developing in inflorescences of four species of burdock ( Arctium tomentozum, Arctium minus, Arctium lappa, Arctium nemorosum ) on the territory of Yelabuga District of the Republic of Tatarstan. Seven experimental sites were examined, their total area is 1,0 hectares. The basic research was conducted during the spring-summer period in 2015-2017 at the time of active flowering plants. There were three kinds of flies-petrotrak (Diptera: Tephritidae), one kind of flies-Midge (in Russian spp.), one kind of beetle-weevil (Curculionidae) and one species of moth (Gelechiidae).

The essay gives a survey of basic research directions in Serbian theolinguistics (in the fields of general linguistics, Serbian studies, Slavic studies and foreign philology), and presents the most important achievements in the fundamental and applicative fields of the study of the sacral language (from the synchronic perspective) which are presented in monographs, papers published in thematic anthologies, proceedings of scientific conferences and scientific journals in Serbia, Montenegro and the Republic of Srpska (with bibliographic references for the 2000-2013 period). Serbian theolinguistics, although in the stage of scientific constitution, potentially has a wide range of fundamental areas of study (some of the main issues from 2000 to 2013 were theoretical and methodological basis of theolinguistics, modern functioning of liturgical languages, confessional markedness of language levels, functional stylistics, genology and stylistics of resources, discourse theory) and spheres of application (lexicography, traductology, linguodidactics). Its perspective in the forthcoming period lies in strengthening the ties with leading centres of theolinguistics in the Slavic world and the integration of researchers of philological and theological profiles in order to further its development.

AbstractTemperate deciduous forests dominated by oaks cover extensive areas in European lowlands. These ecosystems have been under intense anthropogenic use for millennia, thus their natural dynamics, and their regeneration in particular, is still not well understood. Previous studies found that pedunculate oak (Quercus robur), one of the most widespread and abundant species in European deciduous forests, regenerates in open habitats and forest edges, but not in closed forest interiors. However, these observations usually come from the core areas of the biome, and much less is known about such processes at its arid boundary, where limiting factors may be different, and climate change may first exert its effects.In a full factorial field experiment, we tested the effects of different habitats and increased growing season precipitation on the early regeneration of pedunculate oak in a forest-steppe ecosystem in Central Hungary, at the arid boundary of temperate deciduous forests. We planted acorns into three neighbouring habitats (grassland, forest edge, forest interior) and studied seedling emergence and plant performance under ambient weather and additional watering for four years.In the grassland habitat, seedling emergence was very low, and no seedlings survived by the fourth year. In contrast, seedling emergence was high and similar at forest edges and forest interiors, and was not affected by water addition. Most seedlings survived until the fourth year, with no difference between forest edge and forest interior habitats in numbers, and only minor or transient differences in size (leaf number, height).The lack of oak regeneration in the grassland contradicts previous reports on successful oak regeneration in open habitats, and may be related to a shift from light limitation to other limiting factors, such as moisture or microclimatic extremes, when moving away from the core of the deciduous forest biome towards its arid boundary. The similar number and performance of seedlings in forest edges and forest interiors may also be related to the decreasing importance of light limitation. The above-average precipitation in the year of seedling emergence (2016) might be a reason why watering had no effect on oak regeneration.Overall, our results highlight that oak regeneration and thus forest dynamics may be limited by different factors at a biome boundary compared to its core areas. Indeed, this very simple mechanism (inability of oak regeneration in grassland habitats) may contribute to the opening up of the closed forest biome, and the emergence of a biome transition zone.

Abstract Background: Enterocytozoon bieneusi is the most common species of microsporidia that can infect humans and various animals worldwide. To date, information on the prevalence and genotypes of E. bieneusi infection in cattle in the Republic of Korea is limited. Therefore, in this study, we aimed to investigate the prevalence and genotypes of E. bieneusi circulating in pre-weaned Korean native calves and determine the age pattern of E. bieneusi infection and the relationship between E. bieneusi and diarrhea. Results: The overall prevalence of E. bieneusi was 16.9% (53/314) in pre-weaned calves by PCR. The prevalence of E. bieneusi was the highest in September (36.2%), followed by March (28.3%). E. bieneusi infection (c 2 = 5.82, P = 0.016) was associated with diarrhea in calves. The present results indicated that E. bieneusi infection was statistically associated with calf age (c 2 = 11.61, P = 0.003); the prevalence of E. bieneusi was significantly higher in calves aged 21-40 days (odds ratio = 2.90, 95% confidence interval: 1.54-5.45; P = 0.001) than in those aged 1-20 days. Interestingly, E. bieneusi infection showed an association with diarrhea only in calves aged 1-20 days (c 2 = 5.82, P = 0.010). Five genotypes, BEB4 ( n = 12), BEB8 ( n = 23), CHN6 ( n = 1), I ( n = 1), and J ( n = 16), were identified, and all these genotypes belonged to Group 2. The genotype BEB8 was the most prevalent in all age groups regardless of diarrhea. On the other hand, the genotype I was identified only in one calf aged 10 days with diarrhea. Except for CHN6, the four other genotypes were mostly observed in cattle, and all of them have zoonotic potential. Conclusions: This is the first report of the genotypes BEB4 and CHN6 in pre-weaned Korean native calves. The results revealed the presence of zoonotic E. bieneusi in pre-weaned Korean native calves, demonstrating that cattle may play an important role as a reservoir host in E. bieneusi transmission to humans.

The Impact

In recent decades in the world, and in the Republic of Belarus in particular, the question of the impact of weather conditions on the development of sectors of the economy and life of the population has become acute. The sudden changes in weather conditions can lead to adverse and dangerous weather phenomena that cause significant damage to the country’s economy. This paper examines the frequency of dangerous weather phenomena in cyclones of different trajectories that moved through the territory of the Republic of Belarus during the period of 1995–2015. It is identified that southern and western cyclones caused dangerous weather events over the territory of Belarus. The interannual and seasonal frequency of cyclones causing dangerous weather phenomena in Belarus was analyzed. It is shown that the largest number of southern and western cyclones was characteristic mainly for the summer period, as well as the transitional seasons of the year, therefore the dangerous weather phenomena were associated mainly with the development of severe convection on atmospheric fronts. Such phenomena as very heavy rain, snowfall and wind had the highest frequency in cyclones, as in southern as western trajectories. The share of strong sticking of wet snow and large hail were isolated cases and these phenomena were recorded locally over the territory of country.

This article presents the impact assessment results for the spay-dressing of different Metallocene compound fertilizers containing chelated microelements on the yield and quality of winter wheat seeds of the Kazanskaya 560 variety. The research was carried out on the grey forest soils in the Kama region of the Republic of Tatarstan in 2017–2020. The plants were dressed with fertilizers in the autumn and the spring and summer period. In the autumn, we used the fertilizer containing manganese (Metallocene D), and in the spring and summer period (the tillering and earing stages of the winter wheat), we used the Metallocene Universal compound fertilizer with several microelements. During the research, we established that applying the manganese-containing Metallocene D in the autumn has a significant positive effect on the growth and dry biomass accumulation of the winter wheat. The dressing with Metallocene Universal during the tillering and earing stages following the application of Metallocene D in the autumn resulted in an increased/stimulated plant growth and development. The highest yield of winter wheat (3.45 t/ha or 46 % above the reference value) was obtained through the dressing of Metallocene D at a rate of 2 l/ha in the autumn, and the spraying of the plants with Metallocene Universal done twice during the spring and summer period. The autumn application of Metallocene D and the twofold application of Metallocene Universal improve the qualitative parameters of new winter wheat seeds. The use of fertilizers in questions improved the laboratory germination of the seeds and significantly reduced the root rot agent infection rate. The twofold dressing during the spring and summer period following the autumn dressing helped to suppress the most dangerous infections, such as the fusarium blight and the Helmintosporium disease, in the new seeds almost completely. The research conducted showed that Metallocene fertilizers can be successfully used to improve the production of winter wheat and seeds.

Abstract: The article presents the publication and diverse interpretation of a fragment of a rare metal mirror from the collection of the National Museum of the Republic of Tyva (Kyzyl city). The attribution of the composition, placed in the preserved part of the ornamental field of the mirror, required an appeal to the extensive collections of Chinese objects reflected in catalogs and special literature. It is established that the product belongs to a rare group of finds depicting the scene of the conversation “Xu Yu and Chao Fu” — a plot known since the Han Dynasty. An examination of the features of casting, the design of the rim, and the stylistics of the images of the published mirror shows that the manufacture of this item can be attributed to the period of the non-Chinese Jin Dynasty (1115–1234 AD). The significance of the fragment in the system of similar objects found on the territory of Tuva was determined by a review of known finds. The published fragment, the production of which dates back to the Jurchen time, demonstrates the latest period in the distribution of such objects in Tuva. It is important that the product shows a very rare specimen of a mirror, full analogies of which are absent not only in the designated region, but also, as far as we know, have not yet been identified in the sites of North and Central Asia. Keywords: metal mirror, Tuva, museum collections, China, Jurchen time, interpretation Acknowledgements: The study was carried out with the financial support of the Russian Foundation for Basic Research and the Ministry of Culture, Education, Science and Sports of Mongolia within the framework of the scientific project No. 19–59–44013 “Historical, Сultural and Ehnogenetic Processes in Mongolia during the Great Migration and the Early Middle Ages: an Interdisciplinary Analysis of Archaeological and Written Sources”.

The Republic of Turkmenistan is located in the western part of Central Asia and is characterized by a variety of natural conditions. The property of any republic is the preservation of biological diversity of flora and fauna as the main condition for the sustainability of natural ecosystems. However, in recent years, anthropogenic human activity has led to a decrease in this indicator due to the elimination of species. The fauna of Turkmenistan is quite diverse and birds are of particular importance, according to many scientists. The paper analyzes the species diversity of birds in the urbanized landscapes of the Republic of Turkmenistan using the example of the city of Mary, located in the southeastern part of the Turan lowland, in the delta of the Murgab River. During the summer period of 2020, 30 bird species were registered, belonging to 13 orders in 19 families. For the study, a route method was chosen, during which four areas were identified, in which the studies were carried out in sufficient detail: the Bagtyyaarlyk Seilgakhi park, the Murgab river embankment, residential areas of the city (residential area) and the historical settlement Ancient Merv. The ecological and biological characteristics of birds in the study area were studied: according to the feeding habits, according to the degree of attachment to the territory.
