FUNCTIONAL ANALYSIS OF COLEOPTERA (INSECTA: COLEOPTERA) WITHIN CONSORTIA OF THE MOST COMMON XYLOTROPHIC BASIDIOMYCETES (FUNGI: BASIDIOMYCOTA) IN SARATOV REGION

Abstract

Functional groups of connections between mycetophilous coleopterans and xylotrophic basidiomycetes were analyzed, and a heteroconcentric model of the four most common fungi was constructed to determine the structure of mycoconsortium in the Saratov region. Material collection was carried out from 2017 to 2023 in the Gagarinsky, Khvalynsky, Engels, Bazar-Karabulak, Krasnoarmeysky, Tatischevsky, Soviet, Marxovsky, and Soviet districts of the Saratov region. In the course of studying the mycoconsortia of 27 species of xylotrophic basidiomycetes (Polyporales, Agaricales, Hymenochaetales) in the Saratov region, 7 types and 12 functional series of 103 species of beetles from 23 families were identified within 3 groups of consortial connections. The functional spectrum includes topical, trophic, and fensive connections. The topical series encompasses episubstratal-stational and endosubstratal-stational connections. The trophic series includes 5 types of connections (biotrophic, saprotrophic, mixotrophic, necrotrophic, and predatory) and 9 functional series. In the heteroconcentric model, ensembles that include the most comprehensive and distinct groups of connections (topical, biotrophic, saprotrophic, mixotrophic, and fensive) were identified.
