In this work, the main goal was to analyse the erosional hazards within the boundaries of the Kalaus River catchment area.The paper analyses the erosive state of the region's lands, for which industry and cadastral maps, a digital elevation model and satellite images were used. Official data of ministries and departments were used. Geographic information systems – QGIS and SAGA GIS – served as the basis for modelling. The article presents the results of GIS modeling of erosional hazards in the territory of the Kalaus River basin. Based on the (DEM) SRTM digital elevation model, the basic morphometric indicators of the relief were calculated: steepness of the slopes and vertical and horizontal dissection of the relief. Based on morphometric indicators, an integral calculation of the energy of relief and erosion hazard was carried out and a series of relevant thematic maps was created. The values of slope steepness obtained within the boundaries of the basin range from 0° to 51° with average values of 2.5°. The horizontal dissection varies in the range from 0 to 0.84 km/km2, and the erosion bases are characterized by a range of values from – 15.0 to 248.6 m, with an average value of 33.0 m. The formation of the erosional potential of the basin’s relief is facilitated by the location of a significant part of the region on the spurs of the Stavropol Upland, which have widely developed slopes. Based on the calculated raster of the integral energy index of the relief, 3 categories of erosional hazard are identified. Most of the basin of the Kalaus River (58.4 %) is characterised by a low erosion hazard, another 39.0 % of the territory presents an average erosion hazard, and the remaining 2.9 % belongs to territories with a strong erosion hazard. The classification of relief surface shapes based on the Iwahashi and Pike method, which was carried out on the basis of a DEM, shows a much greater prevalence of steep slopes with high convexity in the southern part of the Kalaus River basin.The identified features of the level of erosional hazard of the lands of the Kalaus River basin are recommended to be taken into account in preinvestment, pre‐design and urban project planning of the territories of administrative units located within the boundaries of the basin. Despite the fact that the results of GIS analysis cannot completely replace field erosion surveys, their value as a tool for planning rational land use is obvious. The results of the work can be used to carry out a similar assessment in other regions, primarily in the organisation of agricultural production.

Modeling based on a digital relief model of the spatiotemporal change in the amount of total solar radiation and the assessment of the contribution of locations to the distribution of meteorological elements.DEM analysis was conducted in a GIS environment to assess the spatial and temporal distribution of total solar radiation, and statistical analysis of retrospective climatic and actual (2023) meteorological data was conducted.Based on a digital model of the relief of average spatial resolution in a GIS environment, changes in the spatial and temporal magnitude of solar radiation were estimated. A prospective analysis of climatic conditions made it possible to assess the general features of the climate of the Makazhoy basin Field observations made it possible to characterize modern climatic conditions, as well as to calculate gradients.Depending on the locations, it was determined that the amount of total solar radiation in the Makazhoy basin varies by almost 3 times. Within the same altitude intervals, the difference between the slopes of the southern and northern exposures reaches up to 50 %. The smallest differences in the amount of radiation were observed on the days of the summer solstice, and the largest on the days of the winter solstice. The average annual air temperature in the altitude range of 1960–2264 m in 2023 varied from 8.6 to 5.8°, and the amount of precipitation – from 481 to 525 mm, respectively. The intra‐annual course of meteorological parameters (air temperature and leaf surface, precipitation and relative humidity) within the meteorological transect has been revealed. The data obtained make it possible to proceed to the formation of a GIS system for monitoring the climatic conditions of the carbon landfill of the Kadyrov Chechen State University.

The aim of this study is structural modeling of the impact of the coronavirus pandemic on active post‐pandemic transport in Dorood City, Iran, emphasising both tourism and development of a long‐term tourist market through the promotion of low‐carbon travel markets.The research tool was a researcher‐made questionnaire randomly distributed among citizens of Dorood City. The impact of various factors, including economic, social, medical, and accessibility, on active transportation during the pandemic and its impact on transportation in the post‐COVID‐19 era has been investigated.The social factor has the highest factor load with a weight of 0.94. In contrast, with the lowest factor load i.e., 0.60, the economic factor proved to have the least impact on the choice of active transportation. It was found that the variable of active transport use in the post‐pandemic era with a factor load of 0.66 is the most influential factor, while the social consequences of the pandemic in the post‐pandemic era with a factor load of 0.49 turned out to be the most significant. The least effective ariable was found to occur in the post‐pandemic era.Active transport links during the pandemic in Dorood City with a regression coefficient of 0.77 had a statistically significant impact on the use of this type of transport in the post‐pandemic period. This data can be incorporated in the transport development plan with an emphasis on active transfer as an effective option for the development of sustainable tourism.

This review surveys capabilities of modern instrumental analytical methods that provide low limits of detection for a wide range of elements. Some elements have their own toxic forms, so their identification is of particular importance. Researchers pay increased attention to the content of cadmium and lead due to their high immediate and delayed toxicity.It should be noted that those instrumental methods of analysis that are used to determine these important ecotoxicants are often used to determine other heavy metals. The following objects of analysis are considered – natural, river, sea waters; brines; bottom sediments; plants, including medicinal ones; precipitation; soil; as well as whole blood and blood serum; hair and animal fur; animal organs and tissues. Special attention is paid to eliminating matrix influences and reducing limits of detection using concentration procedures. Various types of extraction, sorption, precipitation, chemical transformation (hydride generation, etc.) are considered and applied to biological and environmental objects.The capabilities of modern instrumental methods of analysis for the determination of heavy metals and important ecotoxicants are considered and compared – single‐element (ETAAS, IVA, etc.) and multi‐element (ICP AES, ICP MS, XRF, etc.). The data is structured in the form of a table, which shows specific analysis methods, indicating the method of sample preparation and/or features of instrumental determination, a list of elements to be determined and the limits of detection.

To identify the main types of hydroecological restriction on the use of water resources and their spatial patterns in the Ural and Tobol river basins within the steppe zone.A comprehensive assessment of the water‐environmental situation in the regions of the studied basins studied was carried out on the basis of the calculation of water‐environmental stress – the ratio of water intake and free flow (average long‐term flow minus ecological). To assess the environmental restrictions on water use, data from the State reports, “On the State and Protection of the Environment" were used. Exposure to the risk of flooding of settlements was analysed according to information from the registers of settlements at risk of flooding (flooding). Analysis of the dynamics of channel processes was carried out using Landsat satellite images. For the rivers of the Tobol River basin, an approach based on taking into account the nature of channel transformations in the sectors of the state border of the Russian Federation and the Republic of Kazakhstan was used.As a result of the research, the main types of hydroecological restriction in the transboundary basins of the Ural and Tobol were identified. In particular, the key factor limiting water use is the availability of a guaranteed volume and adequate quality of water resources. Hydrological restrictions associated with the negative impact of water include the risks of flooding of settlements during the passage of spring or summer floods, as well as intensive riverbed transformations (in the Ural River basin).The Ural and Tobol river basins (within the steppe zone) are characterised by the development of a rather complex hydroecological situation in some areas. Taking into account the long cycle of low water content in these rivers, the general hydroecological situation has aggravated in recent decades, the primary problem being that of guaranteed provision of water resources of standard quality. As a result, an urgent task is to develop an algorithm for a comprehensive assessment of hydroecological restrictions on water use and their consequences for the population and economy of the regions of the steppe zone.

The territory of the south of Russia, within which the North Caucasus Federal District is located, is a most suitable zone for the development of tourism and recreation due to its natural, climatic and geographical components. In this regard, identifying the potential of the tourism sector in the North Caucasian Federal District as one of the promising areas is an urgent task under modern geopolitical conditions.To analyze the level of saturation of the tourist infrastructure of accommodation and the demand for its services in the North Caucasus Federal District, the following indices were calculated: the number of places for tourist accommodation per 1000 permanent residents; number of tourists staying in accommodation facilities per 1 sq. km of territory; number of tourists staying in accommodation facilities per 1000 permanent residents; number of places to accommodate tourists per 1 sq. km. territories.Based on the analysis of the state and development of the tourism sector, as well as the calculated values of tourism infrastructure indices, the main trends in the development of the tourism sector and the problems of its functioning have been identified, which will make it possible to more effectively manage the existing unique tourist, recreational and ethnocultural potential of the territory.The positive dynamics of the main indicators in recent years indicates an increase in the attractiveness and competitiveness of the North Caucasian Federal District as a tourist destination. The analysis of statistical data allows us to draw conclusions about the reorientation of tourist flows from the central regions of Russia to the regions of the North Caucasus.

The aim is to analyse the landscape diversity (LD) of the northern sub‐area of the Volga River delta landscape using a series of mathematical operations.The work is based on full‐stack landscape works including field experiments. Descriptive method, GIS‐analysis and remote sensing data were used in the work.A set of landscape diversity indices was calculated for the northern sub‐area of the Volga Delta landscape on the basis of mathematical apparatus and the entropic complexity of landscape pattern (or Shannon diversity index) of the studied region was estimated. The results of the analysis made it possible to identify two habitats with rather high landscape diversity indices in this region.LD is one of the most important geographical characteristics of the region and allows assessment of the stability of geosystems to anthropogenic loads, reflection on the nature of economic development and use of geosystems and their conservation potential. By comparing HR indicators and retrospective analysis of economic development of the Volga River Delta, it was found that areas with low landscape diversity index were more often used for agriculture, as single large tracts are easier to adapt to economic needs. Areas with a complex morphological structure and, accordingly, a high level of landscape diversity are generally not subject to most types of economic impact.

The purpose of this work was to assess the degree of genotoxic influence of the habitat on individuals of Russian sturgeon and sterlet raised in cage farming conditions in the Volga delta, using micronucleus and DNA comet tests.The blood of the individual Russian sturgeon and sterlet was shaved off during their lifetime. A comet DNA test was performed using the alkaline method. The number of erythrocytes with micronuclei was determined microscopically. To assess the physiological state of sturgeons, conventional hematological and biochemical methods were used.In the samples of fish blood smears studied, the average proportion of erythrocytes with micronuclei was 3.20 ± 1.24 ‰ in Russian sturgeon and 5.25 ± 1.18 ‰ in sterlet. The proportion of DNA in the comet tail in erythrocytes of Russian sturgeon was 3,99 %, and in sterlet 6, 48 %. The values of tail moment and Olivet moment were also lower in Russian sturgeon. Among sterlet erythrocytes, a more heterogeneous pattern of DNA damage can be noted. The length of the comet tail in starlet individuals turned out to be lower than in Russian sturgeon: apparently, larger fragments of these molecules were formed when the DNA of starlet erythrocytes was damaged. The physiological state of sterlet individuals can be characterised as normal, and that of the Russian sturgeon as satisfactory, due to the deviations identified in the values of some hematological and biochemical blood parameters.Having studied the influence of the environment on individual sturgeon kept in cage aquaculture conditions in the Volga delta using micronuclear and DNA comet tests, we can conclude that there was no acute genotoxic effect at the time of the study.
这项工作的目的是通过微核试验和 DNA 彗星试验，评估在伏尔加河三角洲笼养条件下饲养的俄罗斯鲟鱼和鲟鱼个体所处环境对其基因毒性的影响程度。采用碱性方法进行 DNA 彗星测试。显微镜下测定红细胞微核的数量。在研究的鱼类血液涂片样本中，俄罗斯鲟鱼微核红细胞的平均比例为 3.20 ± 1.24 ‰，鲟鱼为 5.25 ± 1.18 ‰。彗尾 DNA 在俄罗斯鲟红细胞中的比例为 3.99 %，在鲟鱼中的比例为 6.48 %。俄罗斯鲟鱼的尾矩和奥利维矩值也较低。在鲟鱼红细胞中，可以发现 DNA 损伤的模式更不均匀。小星红细胞的彗尾长度比俄罗斯鲟低：显然，当小星红细胞的 DNA 受到破坏时，会形成较大的分子碎片。在使用微核试验和 DNA 彗星试验研究了环境对伏尔加河三角洲网箱养殖条件下的鲟鱼个体的影响后，我们可以得出结论，在研究期间没有出现急性遗传毒性效应。

To analyse the literature data on the survival pathways of heterothermic endotherms in unfavorable environmental conditions, during periods of low availability of food resources.The article provides data on the differences between daily and seasonal heterothermy. The features of preparation for hibernation in facultative and obligate hibernators are highlighted. Hypotheses of the origin and evolution of heterothermy are considered. The most probable causes of periodic awakenings of animals from hibernation during the hibernation period are summarised. Considerable attention is paid to the restructuring of energy metabolism during hibernation – the transition from carbohydrate to lipid metabolism. Data have been analysed indicating the importance of fatty acids obtained from food during the active summer period, both for the synthesis of reserve fats and in the regulation of hibernation. Based on data on the accumulation of monoenoic fatty acids in tissues during hibernation, it has been suggested that they have an adaptive significance aimed at limiting oxidative stress and preserving vital cell functions.The data presented can be used both for conducting fundamental research on the adaptive mechanisms of interaction of an organism with its environment, and for solving practical problems, especially when choosing models of calorie restriction or intermittent fasting, as well as studying tissue tolerance to oxidative stress and resistance to the damaging effects of ischemia – reperfusion.
