The article clarifies the morphology, variability, species composition and ecology of the ash genus of theRussian Far East in connection with the prospects for their protection and economic use. Hybridization of ash trees hasbeen proven. In the Far East, 5 species of ash are known: Fraxinus mandshurica Rupr., F. rhynchhophylla Hance,F. densataNakai, F. stenopterus Urussov and F. sieboldiana Blume var. serrata Nakai. To study the variability of species, a gene-ecological decoding of specific characters was used, which makes it possible to clarify taxonomy and biology. The article describes the critical signs of ash trees, indicates the places of their growth.

This paper presents the results of the study of lichen flora in swamp complexes of Sakhalin Island, obtained during expeditionary research in 2005–2009 and 2014–2020. The revealed species composition of lichens includes 172 species. The 28 of them are new for Sakhalin and 93 are new for the island swamp complexes. Bryocaulon pseudosatoanum is included in the regional and federal Red lists. Lecidea nylanderi is new to the south of the Far East. The information about substrates, habitats and locations is given for all species. The data on the distribution in the south of the Far East and, in some cases for all Far East, are listed for selected species that are new for Sakhalin Island and the south of the Far East. For the first time, a characteristic of the distribution of lichens in oligotrophic, eutrophic and mesotrophic bogs of Sakhalin Island is given.

The article presents research data on studies of the current state of the species composition of medicinal plants growing in the south of the Far East on the territory of the forest area of FSBEI HP «Primorskaya State Agricultural Academy» in mountain cedar-latitudinal forests. Biological harvest, production harvest is calculated, size of usage is established and period of restoration of medicinal plants is determined. The work shows how much raw materials can be harvested during one-time operation of thickets. Analysis was carried out, which made it possible to determine the main species composition of plants in hazelnut cedar with linden and oak and in different-shellfish cedar with yellow birch, to distinguish from them the types of medicinal plants characteristic of these types of forest. It was established that 18 types of medicinal plants are promising for volumetric harvesting of above-ground and underground organs. The yield of the remaining species is insignificant and is possible only with the observance of the rules for harvesting during the take-away measures to increase their phytomass.

The paper investigates cross-cultural differences across Russian regions using the methodology of G. Hofstede. First, it discusses the most common approaches in measuring culture and the application of the Hofstede methodology in subnational studies. It identifies the critical issues in measuring culture at the regional level and suggests several strategies to address them. Secondly, the paper introduces subregional data on individualism and uncertainty avoidance using a survey of students across 27 Russian universities. The data allow to establish geographical patterns of individualism in Russia. It is demonstrated that collectivism is most prevalent in the Volga region, while individualism characteristic becomes stronger towards the Far East. The findings are robust to the inclusion of various controls and different specifications of the regression model. Finally, the paper provides a discussion about the potential of applying the sociocultural approach in economics.
