Characteristics and Main Trends of Anthropogenic Florogenesis in the Southern Volga Uplands
2017
Berezutsky, M.A.
The entire range of aspects of anthropogenic florogenesis in the southern part of the Volga Uplands is addressed. Trends in the anthropogenic dynamics of local flora in the last 100 years have been identified. A shift 50–100 km northward of the southern border of natural habitats of some boreal species (Antennaria dioica (L.) Gaertn., Maianthemum bifolium (L.) F.W. Schmidt, Pyrola rotundifolia L., etc.) has been noted. Data on the adventive flora and modern migration paths of the plants within the study area are provided. The adaptive activity of aboriginal species in relation to the entire range of anthropogenic habitats of the region is characterized. Information on findings of protected plant species in anthropogenic biotopes is provided. Overall, flora aridization and xerophytization have been noted, as has an increased role of tree and shrub life forms in the anthropogenic florogenesis. It is proposed to use a method based on the identification of anthropochorophilic elements in the aboriginal flora to forecast the adaptation of flora to the conditions of anthropogenic habitats.
