XYLOMYCOCOMPLEXES OF SMALL-LEAVED FORESTS OF SOUTHERN URALS: A GRADIENT ANALYSIS
Abstract
The article analyzes the species composition of wood-destroying fungi living on the wood of small-leaved trees in the Southern Urals and Trans-Urals. 184 species of macromycetes, belonging to 88 genera and 36 families of the class Agaricomycetes of the Basidiomycota division are discovered. This comprises 60% of the total species diversity of wood-destroying fungi marked in the region. The greatest species diversity of fungi is observed on the birch wood. The authors analyze the change in similarity of species composition of the local mycocomplexes of different formational mycobiotas, depending on the terrain and in a complex environmental gradient. The paper shows no active reduction of species diversity in the landscape-zonal gradient, but the similarity between the formational mycocomplexes may increase primarily by reducing the participation of specific stenotrophic species.
Key words
Wood-destroying basidiomycetes, mycocomplex, small-leaved forests, gradient analysis of species diversity, complex ecological gradient, the Southern Urals.
