The analysis of specific structure of lichens of the pine and birch wood in the neighborhood of Big Kyzykul Lake (Minusinsky District, Krasnoyarsk Krai)

Abstract

The paper presents a multidimensional analysis of pine-birch forest lichens in the vicinity of Big Kyzykul Lake (Minusinsky District, Krasnoyarsk Krai). The studies on the species composition of lichens were conducted from 2013 to 2016. The material was collected in the summer and autumn months by the route method. Based on the authors own collections, the species composition of lichens was determined for the first time, including 46 species from 22 genera and 11 families. The paper presents a list of lichen species of the study area with the indication of the Russian and Latin names, families to which they belong, life forms, ecological groups, the substrate the species grew on as well as the years of collection. The systematic analysis has determined a predominance of the families Parmeliaceae and Cladoniaceae, and genera Cladonia, Hypogymnia, Usnea, Physcia. The analysis of life forms has showed a predominance of bushy (20 species) and leafy (17 species) lichens. The ecological analysis has revealed a predominance of mesophyte lichens (37 species). The substrate analysis has showed a dominance of a group of epiphytes (32 species), which mainly settle on the base, trunks and branches of pine. In total, 4 forophytes have been identified in the study area Pinus sylvestris, Picea abies, Betula pendula, Populus tremula. The forophytes like the Picea abies and the Populus tremula in the vicinity of Big Kyzykul Lake are represented by single young specimens, in this regard, and epiphytic lichens on them are insignificant.
