The chapter presents the results of research in the Republic of Buryatia, where the number and area of fires have increased over the past 20 years due to the rise in temperature and aridity. Most of the fires are registered in the large river valleys where pine forests are formed, which have low soil moisture capacity. Fewer fires occurred on the Eastern Sayans, Khamar-Daban ridges, and the Stanovoye Highlands, where the precipitation maximum falls. A correlation analysis was carried out between meteorological parameters and fires in climate-contrasting forests. The lack of precipitation at the end of the previous summer, combined with the hot and dry spring weather of the current year, have a significant impact on fires in the arid ecosystems of the Transbaikal middle mountains. In the humid coastal climate of the Eastern Baikal region, the high temperature of the air determines the fires, but there is no precipitation.

Landscape Distribution

Ants of the genus Myrmica Latr. are one of the abundant insects in many ecosystems of the Baikal region. Information on their landscape distribution is of great theoretical and practical value because Myrmica ants have important functions in the terrestrial ecosystems. The ants had been collected in the Irkutsk Region and the Republic of Buryatia from 2002 to 2011. The method of route survey with a strip width of 2 m was used. Garmin GPS 12 was used to register the geographical coordinates of the locations of the ants' nests. The collected ant specimens were fixed and stored in 1.5 ml Eppendorf microtubes filled with 95% ethanol. In total 151 nest samples were investigated. All material used in this study is stored in the entomological collection of the Core Facilities Center “Bioresource Center” at the Siberian Institute of Plant Physiology and Biochemistry SB RAS (Irkutsk, Russia). The analysis was carried out by means of GIS technology. The published map "Landscapes of the south of East Siberia" was the basis for this analysis. The V.B. Sochava’s methodical developments in the field of landscape studies were used. The main mapping units were geomes. Determination of the landscape distribution of ants was conducted by SQL-queries using a vector landscape layer and a point vector layer of the locations of the nests of ants. 14 species were identified during data processing. It has been found that the nests of ants were located within 15 geomes. M. angulinodis and M. ruginodis are the most common ants of the genus Myrmica in the Baikal region. The most of M. angulinodis nests (32.5%) were recorded in mountain taiga larch forests of limited development and the most of M. ruginodis nests (48.6%) are in the foothill subtaiga pine forests. The largest species number was recorded in the foothill subtaiga pine forests (six species) and the mountain west-transbaikalia geosystems of daurian type (five species). A more detailed picture of the landscape distribution of Myrmica ants was obtained in comparison with previous works. The obtained data on the landscape distribution of ants were in good agreement with field and literary data.

The aeolian processes play an important role in the relief formation under the semiarid conditions of the intermountain basins of Southern Siberia. Ancient sand landforms occur in different regions of Siberia — the Ob, Chuya, Аley, Yenisei, Аngara, Selenga, Chikoy, Khilok and Chara river valleys and Lake Baikal coasts. The sandy coasts of Lake Baikal are of great interest in terms of floristic diversity determined by a high degree of endemism. Despite centuries of study of the lake basin, sand vegetation is poorly described in the literature. This study presents an analysis of 184 relevés of psammophytic vegetation from the Republic of Buryatia (Severobaikalsky, Barguzinsky, Pribaikalsky districts) and Irkutsk region (Olkhon Island) obtained in 2009–2014.

Abstract Purpose The analysis of n-alkanes in palaeoenvironmental studies of peatlands is mainly limited to ombrogenous peatlands which are a rare feature in the environment. Using n-alkane and plant macrofossil analysis, we have tracked changes in the environment in the valley of a large Central European river. We tested the possibilities for applying such studies to low-moor bogs which are the most commonly occurring type of bog in the world. Materials and methods Representative peat samples were taken from two profiles in a peatland located in the Vistula Valley (southern Poland), and they were analysed for the occurrence and distribution of biomarkers. The distribution of n-alkanes was determined using gas chromatography-mass spectrometry (GC–MS). The botanical composition of the samples was determined by analysis of plant macrofossil remains, and the degree of peat decomposition was also determined. Results and discussion Samples of low-moor peat were characterised by a prevalence of medium- and long-chain n-alkane homologues, which is typical for higher plants. The variable values of the CPI, CPI (25–31), and the C23/C25 ratio have provided information on the stages of formation of the Zapadź bog. The source of n-alkane differentiation is vegetation change related to palaeohydrological dynamics and palaeoenvironmental conditions within the peatland. Conclusions We have shown that analysis of n-alkanes can be successfully used in low-moor bogs as a complement to palaeobotanical and palaeozoological methods. The bringing together of these types of research enables changes in the ecosystems of large river valleys to be tracked.

The Republic of Serbia is а continental country located in the western part of the Balkan Peninsula, in Southeast Europe. In terms of physical characteristics, Serbia is divided into two parts: Pannonian part and mountainous part. The northern part of the country is located in the valley of the Middle Danube, the Sava River valley and the Tisza River valley. In the middle part of the country, the river valleys of the Drina, the Kolubara and the Morava are located. For the purposes of this research, the authors have used the annual precipitation data from 15 meteorological stations distributed throughout the Republic of Serbia. The data from these meteorological stations for the period between 1991 and 2019 has been provided by The Serbian Institute of Meteorology and Hydrology. This data has been used to calculate the annual amount of precipitation, and the trends in annual precipitation.

In the European part of Russia, the highest number of hemorrhagic fever with renal syndrome (HFRS) cases are registered in the Volga Federal District (VFD), which includes the Republic of Tatarstan (RT). Puumala orthohantavirus (PUUV) is the main causative agent of HFRS identified in the RT. The goal of the current study is to analyze the genetic variations of the PUUV strains and possible presence of chimeric and reassortant variants among the PUUV strains circulating in bank vole populations in the Trans-Kama area of the RT. Complete S segment CDS as well as partial M and L segment coding nucleotide sequences were obtained from 40 PUUV-positive bank voles and used for the analysis. We found that all PUUV strains belonged to RUS genetic lineage and clustered in two subclades corresponding to the Western and Eastern Trans-Kama geographic areas. PUUV strains from Western Trans-Kama were related to the previously identified strain from Teteevo in the Pre-Kama area. It can be suggested that the PUUV strains were introduced to the Teteevo area as a result of the bank voles’ migration from Western Trans-Kama. It also appears that physical obstacles, including rivers, could be overcome by migrating rodents under favorable circumstances. Based on results of the comparative and phylogenetic analyses, we propose that bank vole distribution in the Trans-Kama area occurred upstream along the river valleys, and that watersheds could act as barriers for migrations. As a result, the diverged PUUV strains could be formed in closely located populations. In times of extensive bank vole population growth, happening every 3–4 years, some regions of watersheds may become open for contact between individual rodents from neighboring populations, leading to an exchange of the genetic material between divergent PUUV strains.

In the late XIX – early XX centuries, the Buryat people were struggling to survive due to numerous social problems that had accumulated over time. The absence of basic sanitation, low cultural level and moral standards, widespread alcoholism led to mass infectious diseases and issues in reproductive health. The established menacing situation is described by the researchers, medical personnel, and representatives of the European academic science, who worked in the Baikal Region at that time. The goal of this article consists in giving an outlook on the situation from the perspective of Buryat society. The research employs the analysis of previously unpublished materials stored in the State Archive of the Republic of Buryatia and State Archive of the Irkutsk Region. This article is first to publish the notes of the little-known Buryat researcher Mangutkhan Malasagaev. He lived his entire life in the Baikal Region, was engaged in the traditional peasant activities, and thus can be considered a true representative of the Buryat people. His elementary education and lively analytical mind allowed him keeping records of his own observations, and thus leaving a range of manuscripts that describe and analyze various aspects of life of the Buryat people. The article presents his observations on social problems of the Buryat society.

The data on the distribution and habitat confinement of one Mantodea species and44 Orthoptera species in the Mordovia State Nature Reserve are given. Of these, one species of Orthoptera (Calliptamus italicus) isrecorded for the first time for the Mordovia State Nature Reserve, four species (Mantis religiosa, Phaneroptera falcata, Conocephalusfuscus, Tettigonia caudata) are recently penetrated, one species (Conocephalus fuscus) is reported in the Republic of Mordovia for thefirst time. In the fauna of mantids and orthopterans of the Mordovia Reserve, three ecological groups were identified: polytopic, notconfined to certain biotopes (14 species), hygrophilous representatives of intrazonal habitats (5 species) and xerophiles. Among thelatter, there are species of extrazonal habitats (13 species) and confined to dry pine forests (7 species). The steppe group was notrepresented. For the three key habitats with the largest number of identified species, brief botanical descriptions are given. Factorsinfluencing the species composition and current state of fauna of mantises and orthopterans of the Mordovia Reserve are discussed, andmeasures are proposed for the conservation of vulnerable species.

The Baikal region, which includes 3 constituent entities in the territory of the Russian Federation - the Republic of Buryatia, the Irkutsk Region and the Trans-Baikal Territory - should be considered due to its location (in the territory of the Lake Baikal drainage basin) and from the point of view of the regional economy as a single socio-ecological and economic system, whose development should be aimed at preserving the unique ecosystem of the deepest lake on the planet. However, in the Territorial Development Strategy of the Russian Federation, the Baikal region is not included in the list of macroregions despite its compliance with the general principles of their formation. In our opinion, the Baikal region is united by a specific mission entrusted to its population - the need to preserve the unique Baikal ecosystem while ensuring a decent level and quality of life for people living in the Baikal natural territory. The article analyzes the need for a transition to an environmentally oriented innovation economy, which allows transforming the "Baikal factor" from a problem that hinders economic growth into a resource for territorial development.

The article is devoted to the economic rivalry of two Trans-Baikal cities, such as the chief town of the district Verkhneudinsk and the regional town Chita, for the leadership in the region which began with the foundation of the Trans-Baikal region and the appointment of Chita as its capital. Unspoken competition was manifested in determining the status and role in the Trans-Baikal economic area, the place in the regional market system, and the development of banking and railway infrastructure. Despite the fact that Verkhneudinsk had better starting opportunities (a higher level of economic and cultural development), it was almost always in the role of the one which catches up. The status of the administrative center of the Trans-Baikal Region gave Chita the opportunity to «work ahead of the curve». However, the victory in the final round of the competition remained with the chief town of the district, which, however, did not manage to take advantage of its fruits. The author's task is to reconstruct the stages of this peculiar competition and determine the factors that influenced its outcome. The analysis of the sources, first of all, the documents of the State Archive of the Republic of Buryatia, allowed to make the conclusion that the decisions made by the imperial center in relation to both cities were based on the geopolitical factor. It was the task of strengthening Russian influence in the Far East that dictated the deployment of infrastructure facilities in Trans-Baikal cities, which increased their economic status.
