The research was conducted on the structure and characteristics of the growth of shoots of the genus Viburnum L. There are significant differences in the structure and dynamics of growth within the genus, so the determination of the structural features of the shoots of species of the genus Viburnum is relevant. The research of the dynamics of shoot growth was carried out according to the method of A.A. Molchanov and V.V. Smirnov (1967). The species studied by us belong to three sections of the genus Viburnum; the peculiarities of buds structure generally determine the structure of the shoots in the species of each section. It was found that the type of each of the three sections of the genus is characterized by a special structure of the shoots. It has been studied the rhythm of growth and development of native and introduced species of the genus Viburnum L. The terms of shoots growth of the species of the genus were analyzed, and the length of the annual growth of shoots was determined. Phenological date of the beginning and end of shoot growth was established. It was revealed that the onset of individual phenophases quite clearly correlates with the sum of effective temperatures above 5 ° C. The species of the genus Viburnum are characterized by the following types of shoots: tillering, stem, generative. Intensive growth of shoots of all studied species occurs in May - mid-June. In the species of the section Lantana, there are 2 peaks of shoot growth - May and mid-July. According to the duration of growth of shoots, viburnum can be divided into two groups: 1) with a short period of growth (65 - 75 days): V.opulus L., V.sargentii Koehne, V.prunifolium L., V.rufidulum Raf., V.lentago L; 2) with a long period of growth (100 or more days): V.lantana L., V.carlesii Hemsl., V.veitchii C.H. Wright, V.rhytidophyllum Hemsl., V.buddleifolium C.H. Wright, V.burejaeticum Rgl. et Herd. The data obtained demonstrated that the greatest annual growth of all Viburnum species was recorded at the age of 4-7 years. A decrease in the annual growth of axial shoots states the need for works on preliminary rejuvenation of the bush.

In 2017, the 90th anniversary of the senior lecturer of the Department of Geobotany and Plant Ecology of St. Petersburg State University, Honored Ecologist of the Russian Federation, Yu. N. Neshataev (1927–2006) was celebrated. This paper contains a brief review of his researches, as well as the works of his colleagues and students of the Department of Geobotany and Plant Ecology on the study of the unique forests of the site “Forest on the Vorskla river” which is the part of the “Belogorye” reserve (Belgorod Region). For more than 50 years in this place Neshataev carried out researches on the structure, dynamics and functioning of forest communities. New approaches and a multilateral analysis of the structure and dynamics of oak forests in forest-steppe zone were realized in the works of his colleagues and pupils, who continued and developed his ideas.

The analysis of landscape differentiation of the low-mountain Maima basin was performed due to the field studies for different periods as well as the remote sensing data. The formation of modern landscapes of the basin depends on regional features related to geographical location of landscapes on the periphery of the mountain region (mainly in its low-mountain part) and local factors as well. Structural-lithological and geomorphological heterogeneity, high-altitude along with climatic background parameters determine the development of the landscape structure of the territory. The basin map represents the peculiarities of current landscapes arrangement at the local level (groups of stows, their spatial modifications) and atregional one (subtypes of landscapes). In the forest-steppe area, slopes (4-10 and 10-20) of the southern, western and eastern aspects with grass-forb real and steppe meadows dominate. Sub-taiga landscapes are represented by terraced slopes (10-20) of northern and northeastern aspects with birch-pine and pine-birch forests. Among the chern-taiga landscapes, the slopes (10-20) of the eastern and western aspects with birch-aspen-fir forests prevail. Modified and transformed landscapes occupy about 30 % of the basin area due to the largest agglomeration (Gorno- Altaisk, Maima and Kyzyl-Ozek) in the Russian Altai. Secondary grasslands occupy 20 % of the basin area that is mainly related with anthropogenic modifications (deforestation, grasslands). The share of perennial plantations and arable land accounts for 2 %; built – up areas-about 4 %.
