Dikareva T.V., Rumiantsev V.Yu., Soldatov M.S., Malkhazova S.M. PATTERNS OF DISTRIBUTION OF ALLERGENIC PLANTS IN THE PLAIN BIOMES OF RUSSIA // Arid Ecosystems. 2023. Vol. 29. № 3 (96). P. 57-67. | PDF

In this paper we consider the list of species of allergenic plants as well as the species diversity of those plants as a whole in plain regional biomes of Russia. Statistical analysis of correlation between number of allergenic plants in the regional biomes and climatic indices was carried out made. The schematic maps were compiled and analyzed.  It can be assumed that allergenic plants flowering during spring dominate the biomes of broadleaved forests and forest steppe, whereas the number of allergenic species flowering during summer is higher in forest-steppe and steppe biomes. The closest connection was detected between the number of species flowering during summer and average annual temperatures. Comparatively close connection was detected between the total number of allergenic species and average annual temperatures. Nevertheless, connection between the total numbers of allergenic plants in the studied biomes and the biomes aridity appeared to be weak.

Keywords: allergenic plants, regional biomes, climatic factors, aridity, correlation analysis, cartographic analysis.

ABOUT THE SOIL-GEOGRAPHICAL PHENOMENON OF THE EUROPEAN PART OF THE SOUTH OF RUSSIA

Arid Ecosystems

Zalibekov Z.G., Mamaev S.A., Magomedov R.A., Musaev M.A., Musalaeva P.D. ABOUT THE SOIL-GEOGRAPHICAL PHENOMENON OF THE EUROPEAN PART OF THE SOUTH OF RUSSIA // Arid Ecosystems. 2023. Vol. 29. № 2 (95). P. 36-44. | PDF

The territory of the European part of the southern territory of Russia includes regions located between 2 continent-forming seas: the Black Sea from the northwest, and the Caspian Sea from the southeast. The Caucasus Mountains stretch between them in a submeridional direction for more than 1.5 thousand km, varying and in relief elements. To the north, within 42-48°N and 38-49°E, there are temperate and subtropical zones of steppes, semi-deserts, deserts, forest and shrub vegetation (Dokuchaev, 1951).

Within the general laws of the doctrine about the natural zones, some ideas were formulated about the generally accepted parallels and meridians, along which systems with increased geodynamic activity stretch. In some continents, the latitudinal mountain zones are clearly confined to 36-60° parallels, covering a wide range of landscape formation and soil cover. It is well known that the atmospheric pressure is at its maximum within 30-40°N, thus called “roaring forties”. From there the string winds blow, transforming into strong storms of catastrophic consequences that affect the development of aridization and desertification.

Keywords: geographical zones, continents, atmospheric pressure, mountain systems, desiccation, xeromorphism, cartographic analysis, change of soil zones, composition of soil cover.
