The world we live in today holds some uncertainties. The processes of automation, big data, the digital environment, global crises, and the interconnectedness of international society are changing common technological patterns and the educational system. Among the essential features of competitiveness of teachers in higher education are mobility, digital competencies, adaptability, participation in scientific networks and projects, and continuous acquisition of new technological skills. For this reason, teachers must continuously develop their professional skills to remain competitive and create professionals in higher education. Current conditions are fostering global demand for teachers who produce pedagogical and scientific developments.<br /> This article aims to solve the problem of defining the structure, content, and requirements of scientific and methodological support for higher education teachers’ competitiveness in a digital world in the context of global challenges and risks. Theoretically, the problem is defined by the need for new approaches to explaining the concept of teacher competitiveness and the need to develop a psychological and teaching methodology for training and developing teacher competitiveness. In practice, we conclude that researchers must develop personal, professional, procedural, and technological enhancements to support higher education faculty competitiveness in a digital world.

The article presents the results of a research study of anthropogenic affects of gold mining on forest landscapes in Northern Transbaikalia, Russia and processes of natural reclamation of vegetation cover of the disturbed areas. The study area is located northwest of the Maliy Amalat River, which flows along the Vitim Plateau; in the floodplains of its two tributaries the Aunik River and the Bagdarin River. It is an area where a large number of alluvial gold deposits have been discovered. Some of these deposits are currently being developed, some have already been explored, and some have been abandoned. The authors consider the current state of vegetation cover in a key area of the Amalat River basin, near villages of Malovsky and Bagdarin. The problem of natural resources development and conservation is becoming extremely important for the area under study because open-pit gold mining methods that are used here drastically change the environment and affect water, land and forest resources.

The article is devoted to the study of the calcephyte flora of the Small-Amalatian depress. The main objective of the study is to carry out floristic analysis of limestone outcrops. The calcephytic flora was analyzed on the longitudinal element, biomorphological, taxonomic and ecological analyzes were carried out.

The Vitim upland, in the central part of which the Amalat River basin is located, is still one of the least studied floristically areas of Northern Transbaikalia. The flora of the steppe areas (uburs) in this territory still remains unexplored. The study of the flora by the method of specific floras and the identification of diagnostic groups of species in the analysis of geobotanical descriptions using the IBIS program made it possible to identify the features of the steppe communities of the Amalat River basin. It has been established that in the studied territory the uburs are small fragments of steppes (up to 5 hectares) on steep (15-35 °) slopes of southern exposures; the largest area is occupied by steppe communities on the left bank of the river. Quite peculiar steppe communities have been found on carbonates in the upper reaches of the Klyuch Berezovyi, Bagdarinka, Khoigot and other rivers. The flora of the studied steppes is represented by 47 families, 104 genera, and 177 species. An analysis of its arealogical structure showed that boreal species form the basis of the flora of the studied steppe communities, and the combination of species with the South Siberian, North Asian, and Manchurian-Daurian ranges determines its originality. The study of the belt-zonal structure showed a natural predominance of species of the steppe floristic complex (57%), the overwhelming majority of which are mountain-steppe and forest-steppe species; the proportion of steppe species proper is insignificant (9%). The ecological-biomorphological structure is characterized by the prevalence of perennials.
