The article is devoted to the actual topic of expansion of assortment of lianas in vertical gardening in Saratov by the use of introduced species of tree lianas from the Far East. Currently, the studied species: Actinidia arguta; Actinidia kolomikta; Ampelopsis aconitifolia; Schisandra chinensis; Menispermum dauricum — have been distributed in individual land use areas mainly as food crops. It is noted that the far Eastern species of lianas differ in a significant amplitude of biological tolerance of adaptation, have high frost resistance and immunity against diseases. The reason for including these species in the prospective assortment for use in urban plantations is given taking into account a comprehensive assessment of their drought resistance, heat resistance, and resistance to anthropogenic impact. All species are resistant to high summer air temperatures and insufficient humidity, which is typical for the climate of Saratov. The assessment of gas resistance of lianas is given in comparison with the results of studies previously conducted with respect to other species, which allows us to determine possible combinations of plants on landscaping sites. Ranking of species showed that the studied Far Eastern species of lianas have high and medium gas resistance. The obtained data give reason to recommend the studied lianas for use in plantings of various categories in Saratov, depending on the availability of care and air quality. To prevent damage to leaves and shoots by drought, as well as to improve the gas resistance of plants, it is recommended to conduct agro-measures that improve the water-air and food regime of soils in the growing areas.

Preliminary results of the first mycological expedition to the Shantar Islands, where the Federal national park of the same name has been operating since 2013, have been summed up. It includes 15 large and small Islands with adjacent waters. We were able to study the basidiomycetes and ascomycetes species diversity in plant communities on two of them – Bolshoy Shantar and Prokofiev islands. The main feature of the identified mycobiota is the abundance of boreal species that are rarely found in the continental part of the Far East and the weak participation of both background boreal and endemic Far Eastern species.

Three new species of the genus Symmorphus Wesmael, 1836 are described with materials from South Korea and Far eastern Russia: Symmorphus kurzenkoi Kim sp. nov., S. truncatoclypeus Kim sp. nov., S. yamanei Kim sp. nov. All are members of the subgenus Symmorphus Wesmael 1836. S. kurzenkoi Kim sp. nov. is likely to be closely related to Symmorphus fuscipes in having well developed and completely closed propodeal submedian carina, but is clearly different from the latter in the shape of metasomal tergum 1 that is not markedly narrowed toward base. Within the S. murarius group proposed by Cumming 1989, Symmorphus truncatoclypeus Kim sp. nov. is unique in having a clypeus with apical margin completely truncated. S. yamanei Kim sp. nov. is separated from congeners by following combination of characteristics: uniformly lengthened mesosomal setae; vestigial epicnemial carina; areolate mesepimeron; propodeal submedian carina that is somewhat strongly developed though doubled and not clearly closed dorsally; weakly raised basal transverse carina on metasomal tergum 1; faintly foveate-reticulate dorsomedian portion of metasomal tergum 1. Re-description of S. tsushimanus Yamane 1990, which is the most poorly known species in the Far East, is presented based on the holotype. Finally, an updated revised determination key to Far Eastern species, supplemented by digital images and line drawings, is given.

Rhithrogena klugei sp. nov. (male, female and larva) are described from Far East of Russia. The Far Eastern species of Rhithrogena belong to two groups: lepnevae and sibirica. The species group sibirica is represented by the East Palaearctic species R. sibirica Brodsky 1930. The lepnevae species group includes R. lepnevae Brodsky 1930, R. bajkovae Sowa 1973 and R. klugei sp. nov. in the Far East and Siberia, and two species which can be found in the Russian Far East, R. piechockii Braasch 1977 from Mongolia, and R. ingalik Randolph and McCafferty 2005 from Alaska. The species group sibirica differs from lepnevae species group in that its larvae present a rounded projection on gills II–VI on the posterior-dorsal margin, whereas the imagines present a shoot at the base of the penis lobes. The larva of R. klugei sp. nov. differs from those of R. bajkovae and R. lepnevae in their form of gill I and in the ratio of the length to the width of gills III–IV. The male imago of the new species can be distinguished from others of the lepnevae species group by the absence of the latero-dorsoventral tooth on the penis lobes.

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.
