STRUCTURE OF THE EPIPHYTE MOSS COVER ON THE TREES IN MIDDLE TAIGA BLUEBERRY SPRUCE FOREST

Abstract

The paper presents the results of a study of the spatial structure of the distribution of epiphytes on the sample plot, and on the trunk of Picea abies (L.) H. Karst. The distribution of all trees and individual species on the sample plot, as well as most species of epiphytic mosses, does not differ from random. Only one species, namely Dicranum fuscescens Turner, which in this community grows only on the trunks of living trees, has an aggregated distribution, while all other epiphytic moss species are also found in the ground cover and their distribution in the communities is random. The epiphytic cover on the trunk of a spruce tree, in the conditions of the middle taiga blueberry spruce forest, has a structure consisting of stripes and spots of various types distributed along the humidity gradient.
