THE OLDEST CENTRE OF BOTANISTS’ EDUCATION AND SCIENTIFIC RESEARCH (TO 130TH ANNIVERSARY OF THE BOTANY DEPARTMENT OF TOMSK STATE UNIVERSITY)

The history of organization and development of the Botany Department of Tomsk State University is shown as well as the peculiarities of professional botanists’ education and scientific research practice in different historic periods. The main directions of research, being the traditional ones for Tomsk Botanical School, are determined

TYPOLOGY AND CLASSIFICATION OF FLORAS IN COMPARATIVE-FLORISTIC RESEARCH

The possibility of using two approaches in comparative-floristic research is justified. Territorial geographical approach is used quite often and can be considered as a floristic regionalization. Classific-typological aspect of the floristic research can be rarely found. The basic principles and criteria which are used in the classification of floras and the detection of the floras types are investigated. The scheme of classification of the Altai high-altitude floras carried out on the basis of 22 definite floras comparison is shown

Spatial distribution of small-leaved forests in Kuznetskaya depression

The article is devoted to the spatial distribution of small-leaved forests in Kuznetskaya depression where they are forest component of zonal forest-steppe vegetation. Two levels of spatial organization were determined. According to mesorelief communities of different associations are organized into topo-ecological series. These series differ by length and set of communities. On higher level spatial distribution is controlled by climate and reflects zonal structure. Central part of the depression is occupied by Artemisio–Betuletum communities in combination with communities of Calamagrostio–Betuletum which occur in more humid habitats. Near the eastern edge of the depres­sion forest vegetation is represented by combination of Trollio–Populetum and Campanulo–Betuletum communities where the first one is more typical for the plain conditions and second one – for the mountainous environment. In south­ern part of the depression communities of Campanulo–Betuletum are widespread in combination with Saussureo–Populetum communities which localized on higher well-moisturized slopes. In north-western part syntaxonomical diversity drops down to one association – Primulo–Betuletum, and communities of Carici–Betuletum association occur across the whole depression in lowest relief positions. Climatically it is possible to distinguish two belts – forest-steppe and subtaiga. Forest-steppe is represented by two types – typical plain forest-steppe in north-western part and submountainous forest-steppe in the central part of depression. Subtaiga belt in the depression is developed on eastern edge, but in western part it exists only on mountain slopes.</p

Spatial distribution of small-leaved forests in the Kuznetsk Depression

This article concerns the spatial distribution patterns of small-leaved forests in the Kuznetsk Depression, where these communities are the forest components of zonal vegetation. Two levels of spatial forest heterogeneity are described. Depending on mesorelief, forest communities are organized into topo-ecological series, which differ in sets of components and area covered by different elements. On a larger scale, depending on climatic features in different parts of the depression, the spatial pattern of communities and topo-ecological series reflect the zonal structures. In general, the spatial forest distribution is considered as follows: the central part of the depression is covered by Artemisio – Betuletum communities in combination with Calamagrostio – Betuletum forests; approaching the eastern border of the depression, they change to Trollio – Populetum and Campanulo – Betuletum combinations; the southern part is occupied by communities of Campanulo – Betuletum, together with Saussureo – Populetum forests; in the north-western part the only forest association is Primulo – Betuletum. Throughout the entire region, in places with bad drainage occur communities of Carici – Betuletum. Based on climatic parameters, forest-steppe and sub-taiga sub-belts can be distinguished. Forest-steppe in its turn can be divided into an original fragment of plain forest-steppe and typical forest-steppe. In the eastern part of the depression, a sub-taiga sub-belt developed but in the western part, it exists outside the depression
