ZONAL AND AZONAL COMPLEXES OF WOOD-DESTROYING FUNGI OF THE SOUTHERN CISURALS
Abstract
The article distinguishes zonal (steppe and forest-steppe), intrazonal (floodplain) and azonal mycocomplexes in biota of wood-destroying basidiomycetes of the Southern Cisurals. They differ in species diversity and the representation of stenobiont species characteristic only of a certain mycocomplex. The greatest diversity and originality has been marked in forest-steppe zone mycocomplex. Forest-steppe stenobionts are mostly monomitic, more rarely dimitic species preferring high humidity and rather frequent in the northern forest area, but not typical of the southern steppe zone. The similarity of the species composition of forest-steppe and steppe mycocomplexes is 40,5%, despite a significant proportion of specific species in the zonal forest-steppe mycocomplex. A significant number of species common to different climatic zones is probably determined by the fact that within zones boundaries there is a series of close ecotopes that are experiencing similar conditions for different species of fungi. Differences in species composition and diversity of zonal and azonal mycocomplexes are determined by the differences in zonal environmental conditions and also differences in representation within climatic zones typical of regional ecotopes.
