DIVERSITY AND TAXONOMIC STRUCTURE OF DISCOMYCETES OF URBAN PLANT LANDSCAPES OF NOVOSIBIRSK AKADEMGORODOK

Filimonova Darya A., Vorob’eva Irina G.

The article presents the results of the study of the taxonomic composition of the discomycete biota of the Novosibirsk Akademgorodok, a cultural heritage site of the Russian Federation. According to the data obtained, operculate discomycetes predominate (65%) in the studied urban plant landscapes that are not specially protected natural areas. The Shannon index values are 6.84 for "Foxes' Hills", 6.71 for Pirogovsky Forest, and 4.13 for Shlyuzovsky Forest-Bog Complex "Skazochny" (SFBC); which indicates that the diversity of mycobiota in the first two landscapes is higher than in the SFBC. The Simpson index for the specified territories was 0.68; 0.53 and 0.56, respectively, which indicates that dominant species can be identified in the territory of "Foxes' Hills", while in the SFBC and Pirogovsky Forest, discomycetes are represented more evenly. Cluster analysis of mycobiota of the specified plant landscapes using the Shimkevich–Simpson coefficient revealed a similarity in the structure of discomycetes in the Pirogovsky Forest and "Foxes' Hills."
