Abstract: | On the basis of syntaxonomy of primary forests in the Southern Ural region, an analysis of trends in the formation of their
species diversity has been performed in regard to heat supply, soil moisture, and general soil richness. The roles of environmental
factors have been estimated using Landolt’s scales. The results have shown that communities of forest classes Querco-Fagetea,
Brachypodio-Betuletea, and Vaccinio-Piceetea differ in the trends of changes in species richness along gradients of the above
factors. In communities of all these classes, species richness depends primarily on heat supply, with soil richness being
the second most important factor. |
