RESUMO
Communities of xylotrophic basidial fungi of the South taiga subzone of the Middle Urals that are exposed to industrial air pollutants have been studied. We quantitatively assessed the dependence of basic cenotic parameters of xylomycocomplexes on the distance from the source of technogenic pollution and the peculiarities of forest substrates. It was noted that the species abundance and generative and competitive activity of basidial fungi significantly decrease upon approaching the source of air pollutants, and defects in the forest stand moderately increase. A higher activity of the phytopathogenic complex was shown in polluted regions as compared to a control background zone. The data were analyzed using generalized linear model theory. Akaike's criterion was used for the selection of optimal models.
