    In this paper, we assess the diversity of vascular plants in phytocenoses with Quercus mongolica (family Fagaceae) on the territory of the Relic Oaks State Reserve (Eastern Siberia, Transbaikal region), where Q. mongolica is located at the northwestern boundary of the areal. The descriptions of phytocenoses have been processed in the PAST3 application. The similarity of species composition has been determined using the Jaccard index. The resulting tree diagram shows two groups of descriptions at a similarity level of 0.14-0.15. The first group includes the descriptions of mixed forest quadrats, in which Q. mongolica is a co-edificator. The second group of descriptions presents the communities where Q. mongolica is the only species in the tree layer. The analysis of the tree diagram shows the dependence of species richness within the phytocenoses on the surface patterns and edaphoclimatic conditions. The phytocenoses located on steep southern slopes show less diversity

    In this work, we investigated the outer and inner morphological characters of the seeds of 13 species in the family Gentianaceae. We also identified the main morphometric parameters and described the shape, coloration and sculpture of the seed surface. Some aspects of their internal structure were analyzed as well

    O autor deste artigo considera um estudo empírico das orientações de vida dos estudantes e sua inter-relação com a formação profissional. Os principais objetivos do estudo são: conduzir a análise teórica das orientações de vida; compor um bloco de técnicas psicodiagnósticas para estudar orientações de vida entre estudantes de vários programas de estudo ;. O significado prático do estudo consistiu na compilação de um bloco de técnicas de psicodiagnóstico que podem ser usadas para diagnosticar as orientações de vida de uma pessoa e a esfera de valor-significado. Além disso, com base nos dados obtidos, é possível desenvolver suporte corretivo para orientações de vida e características pessoais e pessoais relacionadas da pessoa.El autor de este artículo considera un estudio empírico de las orientaciones de vida de los estudiantes y su interrelación con la formación profesional.

The major objectives of the study are: to conduct the theoretical analysis of life orientations; to compose a block of psychodiagnostic techniques for studying life orientations among students of various programs of study;. The practical significance of the study consisted in compiling a block of psychodiagnostic techniques that can be used to diagnose both the life orientations of a person and the value- meaning sphere. Also, on the basis of the data obtained, it is possible to develop corrective support for life orientations and related individual-personal characteristics of the person

    The paper presents the results of the comprehensive study of Rhodiola rosea L. in natural populations in the Altai Mountains. The phytocoenotic confinement, demographic structure, and morphological characters of 9 coenopopulations of Rh. rosea were studied in different ecological and coenotic conditions in the Chemal and Kosh-Agach regions of the Republic of Altai. Correlation between the morphometric parameters and their calculated values for the shoot and sex of the studied individuals, as well as environmental factors, was revealed. Rhodiola rosea L. is a valuable medicinal plant used for functional diseases of the central nervous system. At present, the natural reserves and areas of natural growth of the golden root have decreased significantly. The species is included in the Red Data Book of the Russian Federation (2008) and many regional Red Data Books of Siberia. In the Altai Mountains, Rh. rosea is widespread throughout the highlands, where it has occupied a wide range of habitats. The study showed that the highest values of ecological and effective density are characteristic of coenopopulations which are part of various hygrophytic variants of alpine and subalpine miscellaneous herbs with a high total projective cover of the herbaceous layer (CP 1, 2, 3, 4). The lowest values were found for coenopopulations growing in communities with a scarce herbaceous layer or dense shrub layer, and on steep gravelly slopes with crumbling soil and nonuniform moisture distribution (CP 5, 6, 8, 9). The studied coenopopulations are normal, full-membered, or incomplete-membered (some of them lack postgenerative individuals). In terms of the ontogenetic spectra, they are mainly left-sided, with a predominance of young generative individuals (CP 4, 5, 7) or bimodal, with an additional peak for old generative individuals (CP 2, 3, 6, 8). Male and female individuals Rh. rosea differ in many morphometric characters of the generative shoots. In some coenopopulations (CP 2, 3, 6, 9), male and female individuals show multidirectional deviation of characters compared to the totality, which indicates that in different environmental conditions these characters are not only genetically determined but can also be related to the sex of individuals

    Studies to assess the pollen quality and pollen productivity of blue honeysuckle were conducted on the ecosystem dendrological territory of the Siberian Botanical garden of TSU (Tomsk). Objects of research: 8 varieties and 4 species of blue honeysuckle – ‘Velvet’, ‘Berel’, ‘Vasyuganskaya’, ‘Zolushka’, ‘Lazurnaya’, ‘Ogneny Opal’, ‘Selena’, ‘Tomichka’, Lonicera altaica, L. edulis, L. kamtschatica, L. turczaninovii. It was found that the ‘Ogneny Opal’ and ‘Velvet’ varieties have low fertility, and the ‘Berel’ and L. edulis have an average fertility. Other varieties and species of honeysuckle have high pollen fertility. The viability of pollen with high values is more than 60 % – ‘Berel’, ‘Vasyuganskaya’, ‘Lazurnaya’, L. turczaninovii, L. kamtschatica, with average values from 40% to 60 % – ‘Selena’, ‘Tomichka’ and L. altaica, with low values – less than 40 % – ‘Velvet’, ‘Zolushka’, ‘Ogneny Opal’ and L. edulis. High pollen productivity – more than 20,000 pollen grains per flower – ‘Tomichka’, L. kamtschatica, L. turczaninovii and L. edulis, average productivity - from 10,000 to 20,000 pollen grains – ‘Berel’, ‘Vasyuganskaya’, ‘Zolushka’, ‘Lazurnaya’, ‘Selena’ and L. altaica, low productivity – less than 10,000 pollen grains per flower – ‘Velvet’, ‘Ogneny Opal’. It is recommended to use at least 10% of varieties with high pollen viability and pollen productivity as pollinators when creating industrial honeysuckle plantations: ‘Lazurnaya’, ‘Vasyuganskaya’, and ‘Berel’

    Approaches to Analysis of Interstate Cooperation

    At the present day cultural diplomacy plays a rather important role in the development of international relations and world politics. This concept is receiving increasing attention from various countries, international and non-governmental organizations and other actors. This trend exists due to a number of reasons, such as the desire of states to create a positive image of their country, the expansion of international cooperation, changes in the global and domestic political situation, the protection of national interests, the prevention of conflicts between states, etc. Cultural diplomacy, beyond historical precedents, consists of a relatively new practice of a country’s foreign policy, which has traditionally focused on trade and security and defense issues. It is true that in European countries there are institutions of cultural foreign relations since the beginning of the century, but in the last decade the issues, related to the projection of the international image of countries, have become more important
