Patterns of population change on the territory of the Khopyor State Nature Reserve have been revealed. The optimal ratios of the muskrat habitat comfort have been determined. The necessity of improving the geoecological monitoring of the Russian muskrat and its habitat is proved.

Федеральные особо охраняемые природные территории Алтайского края: современное состояние и перспективы развития

Одна из важнейших глобальных проблем современности — сохранение природной среды. Гарантией эффективного сохранения природно-территориальных комплексов региона является создание сети особо охраняемых природных территорий (ООПТ), которая обладает репрезентативностью по отношению к ландшафтному и биологическому разнообразию. Также известно, что более строгий режим охраны, который характерен для заповедников и национальных парков, способствует успешной реализации задач охраны природы. В статье рассмотрено современное состояние ООПТ федерального значения Алтайского края — Государственного природного заповедника «Тигирекский» и Национального парка «Салаир», а также перспективы создания проектируемого Национального парка «Горная Колывань». Показано, что действующие и проектируемая федеральные ООПТ в крае располагаются только лишь в его горной части, а природные комплексы равнинной части края, которые также обладают большой природоохранной ценностью, охраняются лишь режимами заказников и памятников природы регионального значения. Площадь федеральных ООПТ за последнее время в крае увеличена с 0,25 до 1,5 % от площади региона, что является одним из самых низких показателей по регионам Сибирского Федерального округа. Создание Национального парка «Горная Колывань» играет большую роль в сохранении природного разнообразияи историко-культурного наследия Северо-Западного Алтая, позволяет объединить разрозненные региональные ООПТ в единое целое на организационном уровне. В случае создания данной ООПТ и придания охранной зоне заповедника федерального статуса доля федеральных охраняемых территорий возрастет до 2,5 % от площади края.

Genus Xanthium (Asteraceae) in flora of the Mordovia State Nature Reserve (Russia)

The history of Xanthium genus research in a protected area in European Russia (Mordovia State Nature Reserve) has been reviewed based on available data (herbarium collections, publications, archive of Chronicles of Nature). We found that X. strumarium was the only species, which has been mentioned in the Mordovia State Nature Reserve since 1939. However, the overview of available data allowed us to conclude that all Xanthium plants found in this protected area to date belong to Xanthium orientale, an invasive alien species.

Rights of women in the establishment and dissolution of marriage in Oman: between CEDAW and sharia perspective

The Sultanate of Oman has acceded to CEDAW in 2005. However, Oman has reservations about a few articles of the said Convention because some of its provisions conflict with Islamic Sharia or Oman's national laws, including Article 16 of CEDAW. Therefore, the objective of this article is to critically analyse Article 16 of CEDAW and the extent to which Oman Personal Status Law addresses marriage and divorce-related issues is compatible or in conflict with the Convention. To accomplish this objective, the research employs doctrinal legal research and an analytical approach to examine the texts of the Convention and their Omani equivalents. The analysis revealed that the courts could enforce the articles of CEDAW to assert rights, except for the provisions that Oman expressed reservations about. Oman has reservations regarding several features outlined in Article 16 of the aforementioned Convention, as they conflict with Islamic Law. The study highlights that the Convention effectively governs certain areas that promote gender equality in family matters, including stipulating that a woman's permission is necessary for marriage and her entitlement to dissolve the marital union by divorce or khulu' under appropriate circumstances. In addition, Oman effectively implements certain provisions of the Convention to strengthen women's rights by modifying domestic legislation. In conclusion, the Oman National Law is consistent with the CEDAW, except for the State's reservations concerning the implementation of Article 16 of the aforementioned Convention.

VERTICAL STRATIFICATION OF SOME FAMILIES OF DIPTERA IN TEMPERATE DECIDUOUS FORESTS (CENTRE OF EUROPEAN RUSSIA) : THE USE OF BEER TRAPS

Diptera is a crucial component of temperate forest systems in Europe. Vertical distribution of Diptera in forests is still insufficiently studied and there are many unanswered questions. The study has been conducted in the Republic of Mordovia (central European Russia). To collect insects, traps with beer and sugar bait were used. Collections were made during the period of June–September 2020 in four sites in deciduous forests. The maximum number of Diptera specimens has been collected at the height of 1.5 m from the ground level, and the minimum at the height of 3.5 m. Species from eight families (Anisopodidae, Calliphoridae, Drosophilidae, Fanniidae, Lonchaeidae, Milichiidae, Muscidae, Tipulidae) represent the main part of the sampled specimens. Calliphoridae, Drosophilidae, Dryomyzidae and Tipulidae, were most abundant at the height of 1.5 m from ground level. At the height of 12 m in the canopy, Anthomyiidae, Chloropidae, Lonchaeidae, Milichiidae, Periscelididae and Syrphidae were most abundant. Numbers of Fanniidae and Muscidae were almost equal at all heights. The species diversity of Muscidae was represented in the traps by 10 well-recofnized species. The most abundant species was Phaonia pallida (70.7%). Two species Thricops simplex (12.2%) and Muscina pascuorum (5.8%) were less abundant. Thricops simplex showed the greatest confinement to the height of 1.5 m, while Phaonia pallida increased in abundance from lower to higher levels of the forest community. The vertical distribution of Muscina pascuorum did not depend on the height of the trap. Key Words: beer trap, Mordovia State Nature Reserve, insects, dynamics, number

Factors influencing sustainable development in Eco-tourism settlements: A comparative analysis

This study examined the determinants of sustainable development within national parks and ecotourism settlements across both Tajik National Park and Fann Mountains areas in the Republic of Tajikistan, as well as Zaamin National Park and Hisar State Reserve in the Republic of Uzbekistan. Primary data were gathered from surveys conducted in four distinct settlements across these nations, and subsequent analyses employed descriptive statistics, factor analysis, and Analysis of Variance (ANOVA). The levels of sustainable development varied among the four settlements. The following factors were the most important for sustainable development: active engagement from local authorities and the population, high levels of tourist satisfaction, and attractive sights. The findings of this study have important implications for policymakers and stakeholders involved in the development of national parks and ecotourism settlements in Tajikistan and Uzbekistan. The findings suggest that the following strategies are most effective in promoting sustainable development: encouraging active engagement from local authorities and the population, providing high-quality services to tourists, and protecting the environment.

Analysis and Prediction of Land Use/Land Cover Changes in Korgalzhyn District, Kazakhstan

Changes occurring because of human activity in protected natural places require constant monitoring of land use (LU) structures. Therefore, Korgalzhyn District, which occupies part of the Korgalzhyn State Natural Reserve territory, is of considerable interest. The aim of these studies was to analyze changes in the composition of the land use/land cover (LULC) of Korgalzhyn District from 2010 to 2021 and predict LU transformation by 2030 and 2050. Landsat image classification was performed using Random Forest on the Google Earth Engine. The combined CA-ANN model was used to predict LULC changes by 2030 and 2050, and studies were carried out using the MOLUSCE plugin. The results of these studies showed that from 2010 to 2021, there was a steady increase in the share of ploughable land and an adequate reduction in grassland. It is established that, in 2030 and 2050, this trend will continue. At the same time, there will be no drastic changes in the composition of other land classes. The obtained results can be helpful for the development of land management plans and development policies for the Korgalzhyn District.

Impacts, Potential Benefits and Eradication Feasibility of Aquatic Alien Species in an Integral Natural State Reserve.

Riverine wetlands are stepping-stone environments for the protection of local biodiversity, but they are particularly vulnerable to biological invasions. In order to take action against biological invasions, it is crucial to assess the impacts of alien species. However, it is also important to assess the potential benefits on ecosystem services that alien species could have. Once it has been verified that negative impacts are higher than potential benefits, it is important to propose feasible actions to contrast them. In this study, we assessed eight freshwater alien species recorded in an integral protected wetland using the Invasive Species Effects Assessment Tool (INSEAT) to quantify their negative impacts and potential benefits on ecosystem services. Moreover, for each species, we evaluated the feasibility of the main eradication techniques currently proposed in the literature using the Non-Native Risk Management scheme (NNRM), with the final aim of suggesting effective actions for their management. The INSEAT results indicated that all the assessed species had more impacts than benefits while NNRM provided useful indications on the best practical conservation actions to use for reducing the density, and therefore, the negative impacts on ecosystem services and the local biodiversity of the assessed alien species.

Genomic DNA polymorphism in <i>Myrica gale</i> (Myricaceae) in the Lebyazhiy state Nature Reserve (the southern coast of the gulf of Finland)

The analysis of genomic DNA polymorphism is one of widely used approaches for studying the genetic structure of natural populations. It has been successfully applied to various plants. However, many species have not yet been studied, which is primarily due to methodological difficulties in isolating well-purified and non-degraded genomic DNA. These difficulties are due to the fact that plants possess numerous bioorganic compounds (polysaccharides, polyphenols, lipids, etc.) that contaminate DNA and significantly reduce its quality. Such species include marsh waxweed (Myrica gale L.), a perennial sub-Atlantic shrub with presumably vegetative propagation (in nature, waxweed seedlings are quite rare). We developed a simple protocol for isolation of high-quality genomic DNA from waxweed leaves and performed AFLP analysis of 42 plants of this species from three subpopulations in the Lebyazhiy Nature Reserve. Using three primer pairs, we isolated 22 amplification fragments, 8 of which were monomorphic. For the remaining 14 fragments, the average level of their polymorphism was low: depending on the subpopulation studied, it varied from 0.079 to 0.129. As shown by our analysis, all three studied subpopulations are polymorphic with a predominance of two common AFLP-genotypes. The corresponding plants are apparently the vegetative descendants of the founders. The rare AFLP-genotypes (represented by just one or two plants; a total of 12 such genotypes were identified) are likely the result of mutational and recombination processes. Our data give evidence that in the life cycle and dispersal of waxweed, the role of sexual reproduction is also noticeable.

Allelic diversity of the SSR locus VVIB23 linked to the flower sex in wild-growing grapevine genotypes of Krasnodar Territory

Background. Studying wild-growing grapevines is of interest because it expands the knowledge on the genetic diversity within the gene pool and helps to search for new resistance sources. One of the main differences between wild vines and cultivars is the type of their reproductive system: wild grapes are represented by cross-pollinated dioecious vines, while cultivated ones are, with rare exceptions, hermaphrodites capable of self-pollination. A DNA marker applicable to determine the grape flower sex has been identified.Materials and methods. The VVIB23 DNA marker to the Sex gene determining the flower sex was used to study 36 genotypes of wild-growing grapes selected in 2019–2021 within the Utrish Nature Reserve near Gelendzhik and the Krasny Les State Nature Reserve on the right bank of the Kuban River. PCR technique was applied, and the results were evaluated on a Nanofor 05 genetic analyzer.Results. The studied grapevine accessions were found to be variable for the VVIB23 SSR locus: 7 types of alleles were identified. Alleles corresponding to the male flower type were present in 14 genotypes, and those corresponding to the female type in 21. A PCR fragment whose size, according to the published data, correlated with hermaphroditism was not found, which is typical for wild genotypes. The DNA marker analysis failed to determine the flower sex of one accession.Conclusion. The results of the DNA marker analysis showed that the studied wild-growing grapevine genotypes were dioecious forms

Fauna of sone groups of invertebrates of Erebuni State Reserve (Armenia

Aim. The aim of the work is to research the fauna of invertebrates in the Erebuni State Reserve. Material and Methods. As research material served invertebrates gathered in the Erebuni State Reserve. The work was carried out at the Scientific Centre for Zoology and Hydroecology, National Academy of Sciences, Republic of Armenia in the period 2019–2023. The material was from our own collections, as well as from collections of insects and mollusks of the Institute of Zoology. The identification and collection of insects and mollusks were done using standard methods. Results. An overview of some groups of invertebrates in the Erebuni State Reserve is here provided for the first time. As a result of the research, 35 species of Diptera, 15 species of Coleoptera, 44 species of Lepidoptera,10 species of aphids and 12 species of mollusks were identified. Some species are listed in the “Red Book” of Armenia and are under the protection of the state, and there are rare species and species found in the Republic of Armenia only in the reserve. 15 species of insects identified by us develop on 4 plant species included in the “Red Book” of Armenia. Conclusion. The Erebuni State Reserve is represented by a rather diverse and valuable fauna of invertebrates studied by us, including a number of rare and protected species. Species of invertebrates associated in their development with valuable wild, economically important and protected plants have been identified in the reserve. Identification of species diversity and trophic relationships of some groups of insects that develop on rare and protected plants of the reserve is relevant for natural areas under state protection, of which the Erebuni State Reserve is one.

Fauna and biotopic distribution of Chrysomelidae (Coleoptera) in the Shaitan-Tau State Nature Reserve, Russia

Research on taxonomically diverse groups of insects are an important component of studying biodiversity in Protected Areas of various ranks. Based on the results of original studies (2017–2020), this paper presents for the first time data on the Chrysomelidae family and its species composition in the Shaitan-Tau State Nature Reserve, Russia. The study area is located in the south of the forest-steppe zone of the low mountains of the Southern Urals in the Orenburg Region, Russia. Currently, this Chrysomelidae fauna is one of the most studied ones in Protected Areas of the Southern Urals. In the study area, 180 Chrysomelidae species have been registered, which is 51% of the Chrysomelidae family in the Orenburg Region. In addition, 86 recorded species were found for the first time in the Shaitan-Tau State Nature Reserve, including eight species recorded for the first time in the Orenburg Region. A new species of the genus Altica was discovered in the study area. In terms of the level of species richness, the Chrysomelidae family of the Shaitan-Tau Nature Reserve is comparable with or noticeably richer than other local faunas of the Protected Areas of the Southern Urals. At the same time, this Chrysomelidae fauna has fewer species than of other state nature reserves and national parks in the forest-steppe zone of the Volga Upland. Features of the zoogeographical structure of the Chrysomelidae family in the Shaitan-Tau State Nature Reserve include quite a high number of West-Palaearctic species (23 species; 12.8%), many of which are located there on the eastern limit of their natural ranges, and a low proportion of Central Palaearctic species (3.9%). At the same time, two Siberian species were discovered (Labidostomis sibirica and Gonioctena flavicornis), which are located on relict island sites of their ranges in the Urals. These findings noticably distinguish the studied fauna from the Chrysomelidae of the steppe Protected Areas in the south of the Orenburg Region, where a considerable proportion are representatives of the Kazakh-Turanian genesis. The studied Chrysomelidae fauna is characterised by a set of rich groups of steppe, meadow-steppe, nemoral and, to a lesser extent, boreal forms (a large part of which are located on the lomits of their ranges in the study area), as well as a pronounced spatial mosaic of biotopic complexes (e.g. forest, steppe, floodplains). In general, the data presented in this study objectively characterise the Chrysomelidae fauna of the Shaitan-Tau State Nature Reserve as a reference for the Ural oak forest-steppe ecosystem, which emphasises its important role for the conservation of natural complexes, as well as the knowledge of the current state and historical stages of the formation of biota of the western macroslope of the South Urals.

First record of Parmelia asiatica (Parmeliaceae, Ascomycota) in Europe

The lichen Parmelia asiatica (Parmeliaceae), described in 2011 from China (Yunnan province), is reported for the first time in Europe, in European Russia. Since 2013, the species has been recorded in the Russian Far East and Baikal Siberia. The majority of the records are in Protected Areas located in regions with a humid climate, where the preferred habitats are mainly foothill/mountain, humid, mixed or dark coniferous old-growth forests. A critical analysis of the herbarium specimens from the Kerzhensky State Nature Reserve (Nizhny Novgorod Region, Russia) collected by the authors in 2020 allowed us to identify a specimen as Parmelia asiatica. Before this study, only six species of the genus Parmelia were known in European Russia. The present paper contains data on the new record of P. asiatica, its morphology, the species distribution range, and its ecology. The diversity of data collected in Russian state nature reserves (including the new record) proves the need and importance of studying the lichen flora of these territories, since they represent the best-preserved, rare and unique habitats. In particular, the Kerzhensky State Nature Reserve is believed to be located near the contact zone between European and Siberian vascular and lichen flora, which is also confirmed by the here reported record of P. asiatica.

Effect of short-term seed priming on germination of wild-growing plant Scorzonera tau-saghyz

This study examines the efficiency of vermicompost tea, an organic fertilizer, in improving the process of seed germination in rubber-producing plants of the species Scorzonera tau-saghyz. Seeds collected from three-year-old plants within the Karatau State Nature Reserve in Kazakhstan were treated with 5% and 10% vermicompost tea for 2 hours and 4 hours’ exposure. Germination progress was closely monitored over a four-week period, revealing a significant correlation between higher concentrations and exposure times with increased rates of seed germination. In particular, tau-saghyz’ seeds treated with a 10% solution of vermicompost for 4 hours showed 1.3 times higher percentage of germination compared to seed pre-treatment by 5% solution and 1.9 times greater than that of the control. These results provide valuable information on optimizing seed treatment protocols to improve the germination and growth of Scorzonera tau-saghyz seedlings, offering potential approaches for biodiversity conservation and sustainable agricultural practices.

The impact of climate change on the taxonomic composition of the Zagatala State Nature Reserve

Zagatala State Nature Reserve is one of the first reserves created in the South Caucasus. The territory of this reserve, organized in 1929, is 47349 ha. The fact that the Zagatala Reserve is bordered by the Lagodekhi Reserve (Georgia) and the Tiyarta Ban (Russia) further increases its natural conservation importance. The main four factors that influence the climate of the reserve are geographical latitude, the protection of the area from the north by mountain ranges, the presence of a strongly fragmented relief and the height amplitude of the area to be high (up to 360-3600 m). Because the soil is rich and the relief is complex, the flora and vegetation are also diverse. Only 1.6% of its area covered by forest is mainly coniferous Pinus hamata (Steven) Sosn., Taxus baccata L., Juniperus oblonga M.B. species. Pinus hamata (Steven) Sosn., which grows naturally only in Balakenchay basin in Azerbaijan it is sparsely distributed in the not very high mountain range up to 1000 m in height between Balakenchay and Filizchay, at an altitude of 1200 m above sea level. In the Zagatala State Nature Reserve, the main composition of the flora is petrophytes, i.e., rock plants consisting of stony soil.

Paleoenvironmental reconstruction of climate by diatoms from sediments of three deep freshwater lakes of Evenkia (Siberia, Russia)

The study aimed to determine the species composition of diatoms in the bottom sediments of the freshwater lakes Zapovednoye, Cheko, and Peyungda, situated in the taiga zone of the southern region of Evenkia within the boundaries of the Tungussky State Nature Reserve. A total of 255 taxa have been identified in these lakes, with their ecological characteristics also established. The diatom community present in the bottom sediments of the aforementioned lakes showcases species that are common across all three lakes, as well as some that are exclusive to every single reservoir. An examination of the acquired data indicated the existence of overarching trends in the evolutionary trajectory of lakes Cheko, Zapovednoye, and Peyungda. Nevertheless, discernible discrepancies are observed in the species composition of diatoms within their bottom sediments, both in terms of quality and quantity, thereby delineating Lake Peyungda in a distinctive position in comparison to lakes Zapovednoye and Cheko. This disparity is likely attributed to the relatively shallow depth of Lake Peyungda, leading to an inclination towards a heightened level of eutrophication in its species composition, as opposed to the conditions observed in lakes Cheko and Zapovednoye.

Hematological analysis as a method of monitoring physiological status of medium carnivorous mammals in the Russian Far East

Clinical blood analysis is considered not only a method of assessing the health status of individuals, but also their fitness and welfare, although the interpretation of the obtained data is complicated by the combined influence of various factors. For most wild carnivore species, there is insufficient information about the effect of environmental factors on hematological parameters. Mammals in the Far East are exposed to hard seasonal climate changes, and therefore have physiological adaptations that enable them to survive the cold season. The aim of this study was to estimate the hematological parameters of three widespread species of medium carnivorous mammals in this region, namely Meles leucurus amurensis, Prionailurus bengalensis euptilura, and Nyctereutes procyonoides ussuriensis, taking into account such factors as sex, age and season in the Ussuriisky State Nature Reserve (Russia), as well as to identify the most informative blood indicators of the animal physiological status. In spring and autumn of 2014–2023, blood samples were collected from 103 individuals of the studied carnivores. The animals were captured, immobilised, blood-sampled and released in the wild at the capture site. The number of leucocytes was counted in the field, and their ratio was detected on the blood smears in the lab. The absence of sex differences and the presence of age differences in the studied species were revealed, which corresponds to the already known data on the parameters of mammalian blood. In spring, Nyctereutes procyonoides ussuriensis had higher leucocyte count (14.77 ± 1.76 mln/ml and 12.33 ± 1.08 mln/ml (hereinafter, in spring vs. autumn, respectively)), the ratio of neutrophils to lymphocytes (4.87 ± 0.47 and 3.02 ± 0.28), and the percentage of segmented neutrophils (73.12 ± 1.77% and 62.95 ± 2.29%), and the lower percentage of lymphocytes (20.35 ± 1.45% and 25.64 ± 1.49%) compared to autumn. Similar blood patterns were observed in two other species. This may be the result of a decrease in body mass and poor condition of animals, i.e. physiological stress after a long winter period and a lack of food resources. In addition, Nyctereutes procyonoides ussuriensis had higher percentages of eosinophils, basophils, and band neutrophils (7.85 ± 1.61%, 3.69 ± 1.26%, 2.15 ± 0.34%, respectively) than Meles leucurus amurensis (2.55 ± 1.09%, 0.45 ± 0.17%, 0.55 ± 0.18%, respectively) and Prionailurus bengalensis euptilura (1.48 ± 0.59%, 0.30 ± 0.16%, 1.74 ± 0.47%, respectively). These differences are probably determined by the biological characteristics of Nyctereutes procyonoides ussuriensis, since this species is an ideal host and carrier of various diseases, and it also has specific morphological features of blood cells. Thus, our results demonstrate the importance of systematic blood tests and the necessity of considering both species-specific characteristics and environmental factors for assessing animal health.

Mammal inventory using camera traps in the Central Forest State Nature Reserve (West of European Russia)

A mammal species inventory by estimating their richness is the first and necessary task of any mammal monitoring programme. This paper presents estimates of species richness of mammals (mostly medium and large body-sized) in the Central Forest State Nature Reserve (European Russia). Based on data collected in 2023 from 55 camera trap locations (19 676 camera days), 59 035 images of wild mammals were obtained. A total of 18 species were recorded. Of these, ten species were representatives of the Carnivora, four – Artiodactyla, two – Rodentia, one – Erinaceomorpha, and one – Lagomorpha. This amounted to 84% of all potentially camera-trapped mammals observed in the Central Forest State Nature Reserve. The relative abundance index (RAI) and naïve occupancy (ψnaive) were calculated for all species. The most common and frequently recorded were Meles meles (RAI = 4.95; ψnaive = 0.96), followed by Ursus arctos (RAI = 4.39; ψnaive = 1) and Lepus timidus (RAI = 4.08; ψnaive = 1), while the most rarely recorded species were Castor fiber (RAI = 0.01; ψnaive = 0.02), Erinaceus europaeus (RAI = 0.02; ψnaive = 0.04), and Lutra lutra (RAI = 0.03; ψnaive = 0.07). Large and medium-sized carnivorous and omnivorous mammal communities were the fastest and most completely captured. According to the constructed single-season multispecies occupancy model with Markov chains Monte Carlo, camera traps failed to record 4–5 more possible species. These species are likely to be Mustela lutreola, M. erminea, and Mustela nivalis, as well as two invasive species, Cervus nippon and Capreolus pygargus. All the captured species were recorded in total in a short period of time, namely from the end of March to the beginning of May during 1869 camera-days. Two of them (Castor fiber and Erinaceus europaeus) were recorded exclusively at this time, and they were not captured further until the end of the year. This emphasises the importance of conducting mammal inventory, with inclusion of the spring season.
