Paramecium bursaria is a symbiotic ciliate species which cells contain hundreds of algae enclosed in perialgal vacuoles. The aim of the present study was to identify endosymbiotic algal strains of P. bursaria and to define the geographical distribution of the identified species. We analyzed symbiotic strains of P. bursaria originating from distant geographical locations and housed at the Culture Collection of Ciliates and their Symbionts (CCCS) at St. Petersburg University. Based on the obtained results, we identified these strains as Micractinium reisseri , Chlorella vulgaris, and Chlorella variabilis. We did not confirm the occurrence of a division into American and European groups and we guess that this division is only contractual and corresponds to the amount of introns in the 18S rDNA, and that there is no strong correlation with the geographical location. We have demonstrated that the range of M. reisseri is greater than previously supposed. We identified algae strains originating from Southern Europe (Serbia), Western Asia, and from the Far East (Kamchatka) as M. reisseri. Moreover, we identified two strains originating from Europe as C. variabilis, which also contradicts the predetermes about a division into American and European groups.

Gastrocoptaarmigerella (Reinhardt, 1877) has been described from Japan and is widespread in the Far East and China. Surprisingly, a few occurrences in central and western Asia have also become known. Forcart (1935) found G.armigerella in northern Iran. The authors found evidence of G.armigerella in western Tien Shan, Kyrgyzstan. The form from northern Tajikistan described by Schileyko (1984) as G.huttoniana agrees morphologically with G.armigerella as well. Gastrocoptahuttoniana is known from western India and the Himalayan region. The evidence of G.armigerella from central and western Asia has come thus far from drift material at the high water line in river floodplains which suggests that these are sub-fossil or fossil shells (Holocene or Pleistocene) which have been relocated. No living example of Gastrocopta has been found there as yet. Possibly the species is now extinct in this region. Gastrocoptatheeli (Westerlund, 1877) is the most widespread Gastrocopta in Eurasia. Its area ranges from the Caucasus to the Far East. The findings reported here are the first for this species in western Tien Shan.

The paper analyzes the transformation of the female rural population position of the Far East in the USSR in 1970 - the first half of 1980 under the influence of a set of factors. The peculiarities of the geographical location of the region, its level of development, acceleration of life processes in rural areas, rapid dissemination of information and other factors had a significant impact on rural women. This influence was controversial and ambiguous. On the one hand, the role of a woman in the family changed, her activity as an employee increased, her well-being, cultural and educational level increased. On the other hand, becoming more independent, the woman aspired to better working and living conditions, career growth, free time increase, but in rural areas it was difficult. Despite the special attention of the state to the Far East and the activities aimed at the development of rural areas, life in the villages did not meet the urban views of local residents. The result of this transformation was a focus on childlessness for a large part of young people and moving to urban areas. Against the background of the village it was perceived as an incomparably better place of residence.

The article presents an analysis of the demographic problems of the priority geostrategic territories of the Russian Far East. Such territories are characterized in the «Strategy for Spatial Development of the Russian Federation to 2025» as having a particular significance for development of the country as a whole, but differing in special conditions of the population life and functioning of the economy due to their geographical location. The main problem of the Far East geostrategic territories of the country is depopulation, which is both a factor that slows down the socio-economic development and an indicator that characterizes the low performance of this development. Components of the population dynamics that lead to its decline — natural growth and migration flows — are of particular importance. The article identifies multidirectional nature of the main demographic processes — natural growth is mainly combined with migration outflow of the population. The regions of the Far East that managed to increase their population in 2010-2018 with this combination are the Republics of Sakha (Yakutia) and Buryatia. Specific features of the Far East priority geostrategic territories in comparison with Russia as a whole are shown. The analysis is based on the «Municipal Russia» database, which summarizes the demographic statistics for all urban districts and municipal districts of the country, including those located on the priority geostrategic territories. As a result of the analysis of population dynamics, we have identified directions that can lead to an improvement in the demographic situation in the priority geostrategic territories of the Far East, and, accordingly, will contribute to the socio-economic development of not only these territories, but also the entire Russian Federation.

The genus Kirinia was described from the Far East and contains two species, i.e. Kirinia epimenides and Kirinia fentoni (= K. epaminondas). Later, the other four species ranging in Central and Western Asia and on the Balkan Peninsula were transferred to this genus based on morphological features of the male genitalia. This action was incorrect and is not confirmed by our novel molecular data. Here, we restore the genus Esperarge Nekrutenko, 1988 stat. rev. with four species, i.e. E. eversmanni comb. rev., E. cashmirensis comb. rev., E. roxelana comb. rev., and E. climene comb. rev. Additionally, the subspecies Esperarge eversmanni shiva syn. nov. is considered a junior synonym of E. e. unicolor.

Elms have long been important components of the forests and cities around the world. In the little-more-than-sixty years since it was first found in Europe in 1918, Dutch Elm Disease (DED) has killed millions of elms in Europe, Western Asia, and North America (Figs 6 & 7). The Far East is the only major area in the temperate zone of the northern hemisphere that has not had a DED problem. For this reason, and because many species that are native to the Far East are resistant to the Disease, it is thought that DED may have originated in the Orient.

Paramecium bursaria (Ehrenberg 1831) is a ciliate species living in a symbiotic relationship with green algae. The aim of the study was to identify green algal symbionts of P. bursaria originating from distant geographical locations and to answer the question of whether the occurrence of endosymbiont taxa was correlated with a specific ciliate syngen (sexually separated sibling group). In a comparative analysis, we investigated 43 P. bursaria symbiont strains based on molecular features. Three DNA fragments were sequenced: two from the nuclear genomes—a fragment of the ITS1-5.8S rDNA-ITS2 region and a fragment of the gene encoding large subunit ribosomal RNA (28S rDNA), as well as a fragment of the plastid genome comprising the 3′rpl36-5′infA genes. The analysis of two ribosomal sequences showed the presence of 29 haplotypes (haplotype diversity Hd = 0.98736 for ITS1-5.8S rDNA-ITS2 and Hd = 0.908 for 28S rDNA) in the former two regions, and 36 haplotypes in the 3′rpl36-5′infA gene fragment (Hd = 0.984). The following symbiotic strains were identified: Chlorella vulgaris, Chlorella variabilis, Chlorella sorokiniana and Micractinium conductrix. We rejected the hypotheses concerning (i) the correlation between P. bursaria syngen and symbiotic species, and (ii) the relationship between symbiotic species and geographic distribution.

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.
