Ecological Assessment of Changes in Regional Industrial Structures in Russia at the Beginning of the 21st Century
Authors: Klyuev N. N.
Published: April 2024

Structural changes in the industry of the Russian regions for 2005–2019 are assessed from an ecological perspective. The decrease in the share of mining and the share of hazardous activities in industry was considered as an ecologicaly progressive change in the regional industrial structure (its greening), and the opposite change was assessed as de-ecologization. The absolute majority of the main mining regions of the country have increased the extraction of mineral resources, while in half of them it has increased by more than 1.5 times, and in a quarter–more than by half. The north-eastern vector of the development of the country’s mining industry has been clearly identified, which determines the relative shift of large-scale impacts on nature to Eastern Siberia, the Far East, the European North–to ecologically significant and easily vulnerable landscapes of the cryolithozone, as well as to shelf areas. The number of regions where the share of the extractive industry in industrial output exceeds 50% has increased from 9 to 14. In 2/5 of Russian regions, the share of environmentally hazardous industries in the manufacturing sector has noticeably increased. In regions where nature-intensive production is significantly reduced (the Khanty-Mansi Autonomous Okrug, Republic of Tatarstan), industries of primary processing of raw materials appear, which are also not environmentally friendly. Only in Belgorod, Kaliningrad, and Murmansk oblasts industrial structures in general and their processing sectors have become more environmentally friendly. Interregional differences in the level of environmental friendliness of industrial structures have intensified. Difficulties of a methodological and informational nature did not make it possible to establish the relationship between structural changes in the regional industry and the dynamics of impacts on natural components.
Moving Up: Migration between Levels of the Settlement Hierarchy in Russia in the 2010s
Authors: Mkrtchyan N. V. , Gilmanov R. I.
Published: April 2024

For the first time on Russian data for 2011–2020 the flow of population between 7 levels of the settlement hierarchy is estimated. Levels of the settlement hierarchy are represented by cities of different population sizes and their suburbs, other urban and rural settlements. Indicators of migration icrease (decrease) of the population and indicators of demographic efficiency in the form of matrices are calculated for the hierarchy levels. It is shown that the scale of this flow is affected by changes in the system of migration registration in Russia in the 2010s, namely, the automatic return of migrants to their place of permanent residence after the end of the period of registration at the place of residence. The beneficiaries of the population “vertical migration” are cities with over 250 thous. inhabitants, the biggest winners are the urban agglomerations of Moscow and St. Petersburg. Each next settlement hierarchy level gives the population “up” and receives replenishment from the lower “layers.” In contrast to countries where similar studies were conducted (USA, Canada, the Netherlands, etc.), there is no population flow from top to bottom in Russia, and upward flows have a very high efficiency; it is especially high for Moscow, St. Petersburg, and their suburbs. Despite the population movement between neighboring settlement hierarchy levels, its demographic effect is not as great as in irregular migrations. The research calculations are based on the migrants’ individual depersonalized data, which allow detailing migration flows to individual settlements in Russia. Spatial data referencing was carried out based on 15-digit Rosstat codes unique for each settlement. This made it possible to analyze migration not between administrative units, but between settlements grouped by population size. It was also possible to identify the influence of the features of accounting for migration on the population flow between the selected groups of settlements in the 2010s.
Evaluation of Conditions and Factors for the Formation of Regional Air Hubs in Yekaterinburg, Tyumen, Novosibirsk and Krasnoyarsk
Authors: Sorokin O. V. , Voloshok A. S.
Published: April 2024

The article proposes a methodology for assessing the conditions and factors that contribute to the formation of regional air hubs. As conditions, the following are considered: the transport and geographical location and local demand’s volume, as factors–airport throughput, representation of the base air carrier, infrastructure for transfer and the quality of the take-off and landing schedule. For the analysis, four airports: Koltsovo (Ekaterinburg), Roschino (Tyumen), Tolmachevo (Novosibirsk) and Emelyanovo (Krasnoyarsk) were selected that are most suitable for the formation of a regional air hub in them. These airports serve the largest cities and are located on the outskirts of their territorial groupings of cities facing other territorial groupings of cities between which the transfer will be carried out, which is the best combination for forming a regional hub. A regional hub is an airport in a non-capital city that specializes in servicing transfer transportation between different parts of the country. For each condition and factor, the actual or calculated value of the indicator is given and normalized from 0 to 1. Due to the constancy of conditions for a short period of time, in order to increase the potential for the formation of an air hub, the airport administration needs to work with factors, among which the most important, flexible in terms of speed and cost of implementation is the factor of the aviation schedule of take-offs and landings. According to the results of the analysis, the Yekaterinburg airport has optimal conditions for the formation of a hub, but the administration of the Novosibirsk airport operates with factors better, for example, it works on the convenience of transfer connections, interacting with the base air carrier.
China in the Rankings of the World’s Largest Corporations: Shifts in Its Participation in the International Division of Labor
Authors: Rodionova I. A. , Kalashnikov D. B.
Published: April 2024

The article tests the hypothesis that China’s transition to a knowledge-based post-industrial society requires the creation of large national corporations in many industries, and this should be reflected in the rankings of the largest corporations in the world. The analysis methodology is based on the principles of a systematic approach using historical, analytical, mathematical-statistical, and cartographic research methods. The shifts in the industry structure, nationality, and location of the headquarters of the world’s largest corporations by revenue for the period from 1995 to 2021, as well as the goals and strategy of Chinese companies going abroad, are analyzed. It has been revealed that the Chinese government is forcing the formation of large corporations, both state-owned and private, through mergers and acquisitions of numerous enterprises from the same and different industries. It has been revealed that the major activities of the largest Chinese corporations are concentrated inside China to protect domestic markets and national industry from the world’s largest TNCs. Every year China lets foreign companies enter and invest in new sectors of its economy, but only after national firms in the relevant industries have prepared to compete with world leaders. In the rich and sophisticated markets of developed countries, Chinese TNCs are primarily focused not on production, but on the promotion of national products. In developing countries, the largest corporations are building power plants, infrastructure, and basic industries’ enterprises to achieve the goals of the Belt and Road Initiative. As a result, in the international division of labor China is moving from a “world factory” to an innovative leader.
The Volga River Water Runoff in Warm Epochs
Authors: Georgiadi A. G. , Milyukova I. P.
Published: April 2024

Similarities and differences in climatic conditions (air temperature and precipitation), annual and seasonal runoff, as well as hydrographs of the Volga River runoff near Volgograd in the epochs of global warming in the geological past, the period of modern warming (since 1981), and the scenario global warming in the 21st century are revealed. Changes in the runoff of the geological past and the scenario future were estimated on the basis of the monthly water balance model developed at the Institute of Geography of the Russian Academy of Sciences and the equation of the average long-term water balance. The results of traditional and model paleoclimatic reconstructions and climate scenarios of global warming in the 21st century were used as climatic conditions for assessing changes in runoff. Modern long-term changes in the Volga River runoff are analyzed on the basis of ideas about long-lasting contrasting phases. As a result of the analysis, it is shown that the annual Volga River runoff in the conditions of the warm epochs of the Mikulinsky interglacial and the Atlantic optimum of the Holocene (based on traditional paleoclimatic reconstructions) was lower than the modern one. Whereas, according to model paleoclimatic reconstructions of the warm epochs of the Holocene, climatic scenarios of anthropogenic warming, as well as in the conditions of modern global warming, the annual runoff of the Volga River is higher than in the base period. Significant differences in the changes in the seasonal distribution of the Volga River runoff between all the considered warm epochs were revealed. The different nature of these changes is characteristic of the warm epochs of the paleoepochs and in the conditions of scenario climatic changes in the 21st century. At the same time, changes in the seasonal distribution during modern global warming are similar to those that can be expected with scenario warming in the first third and middle of the current century (except snowmelt flood runoff). A close correlation was revealed between the anomalies of changes in the annual air temperature and the annual amount of precipitation in all the considered warm epochs. During the period of instrumental observations, the long-term phases of the increased or decreased water runoff of the Volga River are synchronous with the corresponding phases of the index of the North Atlantic oscillation and the periods of increase and decrease in the annual levels of the Caspian Sea.
On the Ratio of Climatic and Anthropogenic Factors in the Change of the Volga River Runoff

Published: April 2024

Two variants (methods) were used to calculate the contribution of anthropogenic and climatic factors to the change in the annual and seasonal runoff of the Volga River at Volgograd during periods of significant anthropogenic impact on waters (1930–2020 and 2011–2020) compared with the conditionally natural period of runoff formation (1879–1929). The first is based on comparing the anthropogenic change in runoff due to the influence of reservoirs and irretrievable water consumption with the total change in runoff for the comparison periods. In the second variant, the reconstructed conditionally natural runoff during periods of significant anthropogenic impact is compared with the total change in runoff, calculated by the relationship between the Volga River runoff and the runoff of rivers that are indicators of climatic conditions. It is assumed that climatic changes are mainly of natural origin. It is revealed that the influence of anthropogenic and climatic factors on the overall decrease in the annual runoff of the Volga River in comparison with the conditionally natural period is unidirectional and comparable. Both variants of the calculation give similar values for the ratio of anthropogenic and climatic factors in the total change in runoff in the 1930–2020 period. There are more significant differences in the calculations for the 2011–2020 period and in the assessment of seasonal changes, most noticeably manifested in the spring flood and in the winter. Anthropogenic and climatic factors act in the same direction, reducing the flow of the spring flood and increasing it in the winter, mainly due to anthropogenic factors. The existing differences in the ratio of factors can largely be explained by landscape transformations in the Volga River basin, including in river basins that are indicators of climatic conditions. The impact of such transformations on runoff is not taken into account in water management statistics, although in recent decades different types of economic activities in watersheds have largely offset each other in their impact on runoff. The share of anthropogenic factors in the Volga River runoff changes can vary widely depending on the type of water resources use which is be not always rational.

The paper summarizes the data from long-term observations of hydrometeorological parameters in the Caspian macro-region. The average annual air temperature over the past 30 years at stations in the Russian part of the Caspian Sea has increased by 1.0°C and the temperature of the surface water layer by 0.3°C. Currently, the total river runoff into the sea is about 275 km3. The volume of annual runoff from all rivers flowing into the Caspian Sea went down in the 1996–2020 period compared to the 1961–1990 period. The intensity of the decrease in river runoff in the 1996–2020 period averaged 0.12 km3 per year, while the flow of the Volga and Kura rivers decreased most intensively. In conditions of warming and decreasing river runoff, the Caspian Sea level continues to decline, which began in the late 1990s. Due to increasing water scarcity in the Volga River, the level of the Caspian Sea is going down. The trend started in the late 1990s. By the beginning of 2023, the average sea level had reached –28.70 m abs, which is about 2 m lower compared to the level in 1995. The drained coastal territories are assessed at more than 22 thous. km2, mainly in the northern shallowest part of the sea. The changes in the wind regime and the observed increase in the average monthly and yearly wind speeds are compared against those in the standard reference period (1961–1990). It has been established that the easterly and westerly winds, which cause storm surges with devastating impact on coastal territories, have the greatest repeatability. The statistics of surges observed at four marine stations are given for the 2010–2021 period. The amplitude of the wind-induced level fluctuations in the Lagan area reaches a maximum value of 3.0–3.5 m, while it is about 1 m in Makhachkala. An analysis of the seasonal variability of surges is also given.

Published: April 2024

The results of the analysis of multi-year satellite images and long-term field studies of landscape dynamics in different high mountain regions of the North Caucasus are presented. Based on Landsat Analysis Ready Data processing for the 2000–2020 period and geoinformation modeling, the main changes in nival-glacial and forest landscapes have been established. A decrease in the area of snow-glacier complexes was noted (on average by 20.6%) with the largest decrease in the Eastern Caucasus (75.2%) and the smallest in the Central Caucasus (13.4%). Repeated complex descriptions in key areas confirmed the revealed changes, as well as the rise of the border of mountain-meadow landscapes and the heterogeneity of their spatial structure in the periglacial zone as a result of climatic fluctuations. Multidirectional trends in the dynamics of mountain-forest landscapes are manifested in the deterioration of the state, including the drying up of dark coniferous forests and the reduction in their area in the Western Caucasus (Teberda River basin), in the rise of the border and the increase in the area of light coniferous forests in the Eastern Caucasus (Makazhoy depression), mainly beyond due to the weakening in previous years of anthropogenic impact. In the Central Caucasus (Elbrus region), some expansion of forests was noted at the upper border of the forest belt along the bottom of river valleys, in some places on the slopes of the southern points, a decrease in areas of large avalanches and mudflows, including as a result of outbursts of near-glacial lakes. The metachronism of the manifestation of exogenous processes and their spatial heterogeneity leads to the complication of the landscape structure of the zones of their influence due to the combination of elementary landscapes that are at different stages of restoration successions. The increased recreational impact on the mid-mountain and high-mountain landscapes of the Western and Central Caucasus caused the change in the spatial structure of landscapes, especially mountain-forest and subalpine meadows, a decrease in their biodiversity, and an increase in the proportion of anthropogenic complexes in the most valuable landscapes in protected areas.

Overgrazing, grassland degradation, and soil erosion are significant problems in mountain semiarid ecosystems of the Central Caucasus. Semiarid highland grasslands mainly occur on southern slopes with shallow soils covering a rocky impermeable layer. These ecosystems experience more drought than the grasslands on the northern slopes, and like other drylands, they are especially prone to climate change and desertification. Year-round overgrazing in rural semiarid pastures, as a result of the increase in livestock on private farms at the turn of the 20th and 21st century, also contributed to landscape xerophytization and soil erosion. The aim was to define vegetation and soil indicators for the stages of grassland degradation to help land managers make decisions on sustainable grassland management. We identified four stages of grassland degradation and calculated the integral degradation index for each stage. Main indicators of grassland degradation were grass height, vegetation coverage, Shannon index, humus content, and soil moisture. These parameters decreased significantly with each stage of grassland degradation. At the stage of extremely degraded grasslands, there was clear evidence of the spread of drier vegetation types to more mesic types with soil erosion and hydrological change. Regulation of stocking rates at each stage of grassland degradation is recommended to maintain and restore the highland semiarid ecosystems of the Central Caucasus.
Material Elements of the Political Landscape of Moscow as a Capital

Published: April 2024

The urban environment of Moscow is considered through the concept of the political landscape as a complex of environment-shaping, representative objects. The image of the capital is not only the political history of the state, captured in buildings and monuments, but also a mirror of the representations of the national elite about its social support, development prospects, the outside world, and diverse social ideas about space. Official buildings as the focus of the political and administrative functions of the capital and city monuments are shown in the study as the dominant categories of place, a matrix of new representations that determine the evolution of the urban political and symbolic landscape. The objective of the study is to trace the stages of evolution of the most important material elements of the Moscow political landscape: the location, the construction time, the origin, and other features of the buildings of state institutions and monuments. The features of the modern spatial distribution of government buildings and monuments are studied. The historical hyperconcentration of government buildings in the capital center has been confirmed. Two large areas of high concentration of government buildings are identified: around Lubyanka, Kitai-Gorod, Staraya and Novaya squares and within the Moscow City business complex, as well as the relationship between the significance of a government agency and proximity to the Presidential Administration and the Kremlin as the main centers of decision-making. Despite the transfer of several federal agencies outside the center, there has not yet been a noticeable spatial decentralization of the administrative functions of the capital. In turn, the geography of the monuments repeats the general patterns of the capital plan. Their location reveals the radial-ring and sectoral structures of the city, as well as the specialization of districts. The absolute dominants of the landscape are the monuments dedicated to the heroes and events of the Great Patriotic War (more than 40% of the total number of monuments), which is one of the basics of modern Russian identity. The importance and significance of many capital monuments as an element of the political landscape is based on a strong long-term discourse. Despite some changes (the installation of monuments to rehabilitated public and political figures, victims of new wars and terrorist acts, as well as orthodox monuments), the monumental landscape of the capital is quite stable.

Published: April 2024

The discovery of the Bayraki site in Transnistria showed how far from the ancestral homeland—the African continent—and how early (more than a million years ago) the ancestors of fossil man appeared in this region—in the basin of the lower Dniester. Six layers of Early Paleolithic artifacts were found in the section of the parking lot, both in the alluvial and the cover complex of the VII terrace of the Dniester. In the structure of the upper loess-soil strata, three paleosols of the lower and Middle Pleistocene and several levels of paleovresis are distinguished. The age-varying buried small erosive forms made it possible to clarify the number and stratigraphic position of the horizons of finds and paleosols. The two upper horizons of the Acheulian finds are associated with the medium reddish-brown paleosol and its pedosediment. The four lower horizons—the most ancient—are Oldovan, associated with different facies of the alluvial complex. People began to inhabit the floodplain of the Dniester River about 1 million years ago, repeatedly returning to almost the same place for a long time.

A Report on the Ratings of Psychiatrists Using the Psychiatric Impairment Rating Scale: Some Australian Data
Authors: Athanasou James
Published: April 2024

The _Psychiatric Impairment Rating Scale _has been used in Australia for over 20 years to determine a compensable proportion for patients with a personal injury. This study examined the records of the ratings of 30 psychiatrists on the scale. Psychological injury versus other injury was distinguished by the_ PIRS_. Correlations between the aggregate score, the median class and the overall percentage impairment rating were all high (.819 to.960). The distribution of ratings on each of the six sub-functions varied markedly. There was a preponderance of category 3 ratings and the distribution of overall percentage impairment was skewed negatively. The coefficient alpha based on the aggregate score was.731. Independent ratings (N=15) of the same patients, however, showed substantial concurrent stability of judgements.

According to the federal state educational standards, the curriculum for socio-economic and humanitarian students of secondary vocational education (SVE) and higher education (HE) includes disciplines that provide mastery of competencies in the field of information and communication technologies. Along with the course of informatics, they include disciplines of the block “Information technologies in professional activity”: “Information Technologies in Court Activity” (SVE), “Information Technologies in Professional Activity” (for several specialties of SVE), “Information and Communication Technologies in Judicial Activity” (HE), “Information Technologies in Management” (HE), “Information Technologies in Translation Studies” (HE) and several other disciplines.Based on the analysis of scientific literature and an array of manuals — workshops provided to students and teachers by leading Russian electronic library systems (ELS), as well as own pedagogical work in teaching informatics and the block of academic courses “Information Technologies in Professional Activity”, the author proposes a model of training tasks set to be solved during the study of these courses. The relevance of the article subject is conditioned by the necessity to effectively use the time allocated by the curricula of socio-economic and humanitarian training areas of vocational education and higher education for the study of informatics and information technologies in professional activities. The novelty of the results presented by the author is confirmed by the absence of articles and reports on the topic in the Russian Science Citation Index (RSCI) database
Developing the visual competency in the students’ project activity

Published: April 2024

Modern visual culture requires established skills of visual competency from all participants in communication. These skills are necessary, among other things, for creating educational, informational, advertising, and other materials. However, such skills are not always formed during training at universities. Even in the training program for future communication specialists, visual competency is rarely the goal of the study, make the same mistakes occur often in the students’ projects.The students’ visual competency developing methodology proposed in the article is based on the analysis and development of the visual concept of a communication project. The author generalized her own experience of working with students in the direction of training 43.03.01 “Advertising and Public Relations” in the Ural Federal University named after the First President of Russia B. N. Yeltsin.Modern approaches to the formation of competencies necessary for working with visual images in the digital environment are analyzed and systematized: ICT competencies, media literacy, visual literacy, and communicative competency. A set of practical tasks with methodological guidelines for setting the goal and objectives of the project, analyzing the context of communication, collecting visual materials, and creating a visual image of the project is proposed. By the method of systematization of project and didactic tasks, the components of visual competency are revealed.The scientific novelty of the research consists of revealing the didactic content of all stages of developing the visual concept of the project and systematizing the components of visual competency. The presented set of tasks can be applied in practical ICT classes and students’ project activities. The revealed system of visual competency components can be used in the development of methodological recommendations. The article is addressed to media pedagogues, students conducting project activities, as well as specialists implementing communication projects using visual media
A model of recommendation service architecture for the formation of an individual educational trajectory for self-paced massive open online courses studying
Authors: Aldunin D. A.
Published: April 2024

Data analytics tools in e-learning are widely used to improve the quality of massive open online courses (MOOCs), improve learner performance, and keep learners engaged in the learning process. However, the application of these tools and services is limited to the scope of a particular course. A recommendation service can help a learner to build an individual educational trajectory corresponding to their educational goals and existing knowledge and skills, to do it at their own pace, according to their own program and own schedule, and to use the variety of online courses of the whole educational platform. This tool is built based on a mathematical model using boolean programming.The used mathematical model is remarkable because it allows us to distinguish between the determination of an optimal set of MOOCs according to the given criteria and the construction of a schedule from this set. In this case, the optimal set of courses will be found only if it is possible to build such a sequence of courses so that the learner at each stage has all the knowledge and skills necessary to study the next course. This allows for a significant reduction in the amount of computation required.The article provides a list of prerequisites for creating the service, describes a possible architecture of the microservice approach and justifies its choice, presents an example of the used mathematical model, and evaluates the prospects of using the service.The proposed solution may be of practical interest to organizations that own e-learning platforms, as a means of increasing the proportion of students who successfully achieve their educational goals

La presente investigación finca precedentes en sus efectos, que tal vez nadie quiere enfocar o tocar por diferentes cuestiones que no tienen ningún argumento certero o lógico para ahondar o provocar un beneficio en los estudiantes, que en realidad son la labor de ser de toda institución de formación profesional y que, con el sistema Dual, obtendrían las competencias necesarias para su labor profesional encaminadas a integrarse con las necesidades diarias de una institución de educación. El modelo de formación Dual crea excelentes oportunidades y dinámicas entre escuelas y empresas, que al estar en integración forman a los estudiantes con las competencias necesarias de acuerdo con cada perfil de egreso, porque de acuerdo con lineamientos es una necesidad cumplir con un porcentaje de créditos y un porcentaje de competencias conforme a la materia que se valide en el programa de formación Dual de cada institución.
Tracking the Trajectories of Genni Gunn’s Writing
Authors: Saidero Deborah
Published: April 2024

This article examines Genni Gunn’s writing in light of her childhood immigration experience and contends that, despite the crypto-ethnic approach she has adopted vis-à-vis her Italian-Canadian heritage, migration figures prominently in both her fictional and personal works, which bear traces of her autobiographical vicissitudes and reflect her own process of coming to terms with trauma. Indeed, her novels, stories, poems, and travel accounts all develop along shared trajectories, which include not only the obsession with travel, movement, and memory, or the search for identity and interpersonal ties, but also the focus on loss, grief, and abandonment, which are typical psychopathologies of migration trauma. Ultimately, Gunn embraces creative writing as a site of healing from the loss and pain endured as an effect of separation, abandonment, and migration, which are investigated beyond identification with a specific ethno-cultural group to encompass universal human experiences of trauma.

The multilayer (10 layers) Al doped ZnO (AZO) thin films were deposited on glass substrate by sol-gel & dipping method. X-Ray diffraction measurements showed that the AZO films were polycrystalline with a hexagonal wurtzite structure. The morphological properties of the films were analyzed by atomic force microscopy showing continuous and homogeneous film, completely covering the substrates. The thickness, optical constants, optical band gap (Eg) and transmittance (T) of AZO films were assessed by spectroscopic ellipsometry on UV-vis-NIR spectral range. The AZO film has high transmittance above 80% in the visible region and the optical band-gap energy around 3.7 eV. The electrical characteristics regarding conductivity, mobility and carrier concentrations, were measured by Hall Effect measurements (van der Pauw method). The bulk carrier concentration of the AZO film with 10 layers was found to be 1.16x1019 cm-3. The vibrational bands were obtained by Raman analysis. Defects due to oxygen vacancies in the prepared AZO films were evidenced by photoluminescence spectroscopy (PL). The optical and electrical properties of the AZO thin films proved the possibility to be used in optoelectronic applications.

The present research reports the ultrasonic assisted synthesis of ferroelectric cellulose-barium titanate composites (C/BT). As proved by wide angle X-ray diffraction (WAXD) and by scanning electronic microscopy (SEM), the composites consist of perovskite-type barium titanate particles (BT) of 400- 600 nm, disposed around the cellulose microfibers. Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and wide angle X-ray diffraction (WAXD) revealed the modifications of structure/morphologies of the prepared sample as compared to pristine cellulose, with direct consequences on the polymer crystalline domains, on the uniformity of BT dispersion and on the dielectric properties of the composites. The composites obtained by ultrasonic treatment possess high dielectric constants (58.6-140.5), better breakdown strengths (8.9-17.7 kV/mm) and energy storage densities (2.6-9.0 J/cm3) as compared to BT particles, as well as very low dielectric losses (0.27-3 x 10-4) at industrial frequencies (50-55 Hz), the values being dependent on the content of barium titanate and on the preparation parameters.

Published: April 2024

We conducted an untargeted metabolomics analysis of the skin mucus of Near Eastern fire salamanders (Salamandra infraimmaculata) using LC-MS/MS. Samples were collected from salamanders living in three distinct locations along the southern border of their distribution in Israel: Kibbutz Sasa in the Upper Galilee and Manof in the Lower Galilee, both semi-arid mountainous regions, and Dan River, which has a constant year-round water supply with stable temperature. We identified and described 10 metabolites found in the mucus of S. infraimmaculata in all three habitats. These substances belong to various chemical groups, and we provide their chemical structures and secretion levels. Salamanders from Dan had a greater number of metabolites (5 out of 10) at higher concentrations compared to the Manof and Sasa populations. In addition, differences were observed in 6 mucus metabolites among the mountain populations. Findings support the hypothesis that the extreme habitat conditions in the southern range influence the quantity and composition of salamander mucus secretions.
