Most studies of water flea (Crustacea: Cladocera) invasions are concentrated on a few taxa with an obvious harmful influence on native ecosystems, while our knowledge of cases of anthropogenic introduction with not-so-obvious consequences, in most other taxa, is poor. We found in the Volga basin (European Russia) a population that contained D. curvirostris Eylmann, 1887 and its hybrids with D. korovchinskyi Kotov et al. 2021. The latter taxon is endemic to the Far East and it has appeared in the Volga basin as a result of past human-mediated transportation. The population from Bakhilovo is represented by two strongly different groups of the COI haplotypes belonging, respectively, to (1) D. curvirostris and (2) D. korovchinskyi. We detected SNPs in the position 60 of the HSP-90ex3 locus and in the 195 positions of 28S rRNA locus, which differentiate two species. Part of the specimens from Bakhilovo belonged to D. curvirostris s.str., demonstrating homozygote SNP sites in two loci, but two specimens had heterozygote SNP sites in both nuclear loci. They belong to D. curvirostris x korovchinskyi hybrids. Most morphological traits of the females were characteristic of D. curvirostris. We found in some specimens some characters which could suggest their hybrid status, but this opinion is a hypothesis only, which needs to be checked on more ample material. The exact hybrid system in this pond is not known. Moreover, we have no evidences of sexual reproduction of the hybrids; they could reproduce by parthenogenesis only as is known for hybrids of the D. pulex group, or continuously crossing with parents like some members of D. longispina group. However, poor parental D. korovchinskyi was not detected in the pond either morphologically or genetically. The exact vector of its past anthropogenic transportation to the Volga is unknown. Most probably, just ephippia of D. korovchinskyi were translocated replaced from the Khabarovsk Territory to the Samara Area somehow. This is the first report on hybrids within the D. curvirostris species complex. Here, we demonstrated that accurate studies with deep resolution increase the number of revealed cryptic invasions. We expect that the number of revealed cases of cryptic interspecific invasions will grow rapidly.

The article examines the historical aspects of the formation and implementation of the state strategy for the accelerated growth of the electric power industry in the Far East of the USSR in 1964—1991. The problems of power supply of the Far Eastern region of the country are analyzed, programs for the development of the regional electric power industry are considered, the difficulties of their implementation are revealed, structural changes in the industry and the results of electrification of the region are characterized. The author notes that the problems of regional energy supply had not been solved until the end of the Soviet era. The Far Eastern electric power industry continued to be a costly and lagging industry, slowing down the socio-economic development of the region.

Steccherinum aurantilaetum is a predominantly East Asian polyporoid fungus from the Steccherinaceae. It was first discovered in the Krasnoarmeisky District of the Primorye and in the Khabarovsk Territory. Previously, it was known only in the «Kedrovaya Pad» Nature Reserve in the Primorye and in the «Bastak» Nature Reserve in the Jewish Autonomous Region (for the territory of Russia). An original description of the species based on Far Eastern material is given, and a map of the general distribution of S. aurantilaetum is presented for the first time.

The monograph presents the search for solutions to the problems of the Far Eastern region. The proximity of China and the remoteness from the center of Russia make us look for effective measures to overcome the problems of settling the Far East in the context of sustainable economic development of modern Russia. The paper analyzes the problems of the Far East: in industry, agriculture, forestry, energy problems, environmental problems, and provides recommendations for their solution. Considerable attention is paid to migration problems. The experience of China is studied through the prism of bilateral cooperation with Russia. It is intended for students, masters, postgraduates, researchers dealing with issues of macroeconomic regulation and forecasting.

AbstractThe why and the how of knowledge production are examined in the case of the transnational cooperation between the directors of observatories in the Far East who drew up unified typhoon-warning codes in the period 1900–1939. The why is prompted by the socioeconomic interests of the local chambers of commerce and international telegraphic companies, although this urge has the favourable wind of Far Eastern meteorologists’ ideology of voluntarist internationalism. The how entails the persistent pursuit of consensus (on ends rather than means) in international meetings where non-binding resolutions on codes and procedures are adopted. The outcome is the co-production of standardised knowledge, that is, the development of a series of processes and practices that co-produce both knowledge and ideas about the social order in a force field characterised by negotiations and power struggles.

The pre-emptive right to purchase and sell agricultural land by the authorities of the constituent entities of the Russian Federation, the maximum size of agricultural land plots, the allocation of shares among rural residents and some other features of agricultural legislation are restrictions on the realization of the right of rural residents to own land. The lack of adequate infrastructure in rural areas, especially in the Far East that fall under the Far Eastern Hectare project, is also seen as an obstacle for rural residents to exercise their right to land.

The article describes the directions of distribution of books for children in the Eastern regions of Russia that have appeared in the last decade. Based on a combination of landscape-reconstructing principles, surveys, and comparative typological analysis, the article presents data that expand previously studied aspects of the functioning of the main channels for the sale of books for children in the Siberian-Far Eastern region. It is shown that books for children are the largest segment of the Russian book market, which has been growing since 2008. At the regional level, they are widely presented in all book distribution channels: bookselling networks and independent stores; online stores; book departments of supermarkets (non-core retail); kiosks and stalls; book fairs. The purpose of the article is to analyze the current trends in the distribution of books for children in the region. Positive trends typical for the children book market in the Siberian-far Eastern region are identified. They are: the activity of children book supermarkets, the appearance of independent small stores of club-backstage format, the organization of specialized children Internet projects; increasing the importance of regional book exhibitions, fairs, festivals and holidays in the distribution of books for children; projects support by major Russian patrons. The significance of the study of new practices for the distribution of literature for children and youth in the region is determined by their influence on the formation of a new conceptual model for the popularization of reading, based on the idea of culture as a powerful lever of socio-economic development of territories.

The article examines the role of the Far East in modern Russian-Mongolian trade and economic relations. Based on the data of customs statistics, the features of mutual trade of the Far Eastern subjects with Mongolia are determined. The factors determining the growing interest of Ulaanbaatar to Russian Far Eastern ports are identified. Author highlights the Mongolian projects of railways construction, potentially aimed at enhancing transport connectivity with Russian territories, especially in the context of mineral raw materials supply diversification. The «bottlenecks» of the transport and logistics environment in the region bordering on Mongolia – the Republic of Buryatia, are shown. The research findings are applicable to management practices, especially those concerning transport and logistics solutions to ensure Russian-Mongolian trade.

The paper is based on archival materials about the activities of the Kuibyshev Planning Institute of the 1930s. It reconstructs the biography of the Russian and Soviet diplomat, military and academic of the first third of the 20th century, Vasily Lvovich Pogodin (1870 - after 1937). The study reveals a set of documentary evidence on the diplomatic and pedagogical career of V. Pogodin in the first years of the Soviet power, and determines the features of his pedagogical and party activities in Kuibyshev in 1933-1937. The author highlights a special role of the Planning Institute party committee materials as well as the high school workers trade union in the reconstruction of Pogodins biography. The paper emphasizes that Pogodin was considered to be one of the best lecturers of the Kuibyshev Planning Institute and a credible party worker. It is noted that his noble origin, service in the tsarist army and membership in the party of the Social Revolutionaries until 1937 were not the reason for penalties or prosecution by the party or the university administration. As a result, the author concludes that the fate of Vasily Lvovich Pogodin shows an extraordinary character of his personality. He made a brilliant military career in the years of the late Russian empire and became a major general of the Russian imperial army. Then he managed to integrate into the new Soviet system, radically changing the sphere of his activity and having achieved no less outstanding results in diplomacy and education. He became the plenipotentiary representative of the Far Eastern Republic in China, the director of a number of educational and cultural institutions of the Far East, then a professor of political economy in Kuibyshev.
