This paper represents a review of comprehensive research into invasion biology done by Russian scholars for four decades. Invasion biology is a relatively new field of research focused on the study of alien plants, their behavior in new habitats and risks they pose to indigenous species. It is shown that over 40 years, single finds of alien plant species have transformed into a check-list of invasive species in Russia. The most significant invasion pathways were identified, and the rate of microevolutional changes in plant species in their secondary distribution range was determined. Since the most active alien species disperse without regard to national borders, international cooperation is crucial in joint studies of invasive species.

Introduction. Despite numerous research works on international students’ training at Russian universities, no analysis of efforts to increase student body has been made so far. In this paper, the authors analyze various aspects of policies aimed at increasing international students’ body (economic advantages, sociocultural benefits, education system changes, international students’ adaptation management). The goal of the paper is to consider the advantages and disadvantages of the international students’ rise in the total population of Russian universities. Materials and Methods. The study comprised several stages, including statistical data screening, analysis of international students’ adaptation measures efficiency, the education process participants’ survey and observation of the activities of public agencies responsible for international students’ stay and study in Russia. The survey involved about 100 university employees, an equal amount of small and medium business representatives and 500 international students from Russian universities. 500 international students participated in a questionnaire survey, and digital content of Russian universities’ websites has been analyzed in order to obtain data necessary for the study. Results. The study revealed a trend toward a rise in international student body at Russian universities, with advantages including higher universities’ incomes, jobs preservation despite the demographic instability, and development of the region’s small and medium business owing to an increased demand for goods and services. The trend also provided socio-cultural and educational benefits and revealed the need to manage students’ adaptation, as well as to establish and develop interaction between universities and federal agencies. Discussion and Conclusion. The research results provide a contribution to education and student body management and regional business strategy planning. The findings may be of assistance to heads of recruitment agencies and bodies responsible for accompanying international students at the place of stay, as well as to service industry managers.

This article is focused on the analysis of major approaches to plant invasion research used by Russian researchers. They fall within three main groups: 1. Conventional approaches to floristic analysis based on the Russian scientific tradition of floristic research, 2. Approaches focused on the study of the fraction of invasive flora, making blacklists and regional Black books, 3. New comprehensive approaches based on a synthesis of methods used in botany, geo-information technology and population genetics. Multivariate statistical methods allow for the visualization of various data, including those on alien species group structures in various regions. They make it possible to identify boundaries of ecological niches occupied by plants in respect to climate-and-environmental or ecological variables. An assessment of current statistical interdependence between alien plant characteristics and scores of factors limiting their dissemination facilitates the making of predictive models of plant invasion. Examples of multivariate statistical methods used in invasion biology were analyzed, along with different approaches to the study of the variability of alien species. Alien and invasive fractions of the flora of the Trans-Siberian Railway were analyzed not by administrative units but by natural biomes. This approach allowed us to assess the correlation between the number of invasive species with different natural-climatic and floristic characteristics of biomes. The publication of "Black Books" of various administrative subjects of Russia according to a unified methodology allowed us to make an inventory of invasive species over the vast territory of the country. The experience gained by Russian researchers may be further used for developing universal approaches to plant invasion research.

The paper presents scientific views reflecting marketing management specifics which explains the timely character of the study. The argumentative logics has been used to verify the hypothesis about the impossibility to substantiate promising lines of marketing management research without identifying blanc spots in the scientific basis of respective area of expertise. Systemic chronological and retrospective analysis of the theoretical works was employed in order to achieve the results. The findings give a detailed explication of the scientific landscape which reflects the viewpoints of marketing management issues. The main conclusion is that the thesis of the «ideal marketing management» concept which allows for the requirements of all contemporary marketing systems participants to be fully met as of today, has a fragmentary character. The findings can be employed in further theoretical research in marketing and other fields of knowledge.
