Дифференцирующая роль мхов при классификации растительных сообществ

Abstract

The data of long-term bryological explorations in Salair-Kuznetsk region (north-western part of Altai-Sayan Mountain country) and adjacent plains in south-east of West Siberia are generalized and analysed in partial- and coenoflora concepts. The main moss habitats of the territory were recognized in terms of EUNIS-system; 29 from them it is possible to comply with the units of Braun-Blanquet classification. These 29 partial bryoflora drastically differ in volume (the number of species from 5 to 114); the specificity of their compositions is low, most species grow in two or more habitat types. A dendrogram of similarity is calculated by Bray-Curtis coefficient; the resulting clusters correspond well with the classes of Braun-Blanquet classification. The reasons for the clusters formation are briefly discussed.
