By the biology and ecology of endemic Anemonastrum biarmiense (Juz.) Holub in South-Ural State Nature Reserve

The results of study of morphometric parameters of endemic alpine Urals Anemonastrum biarmiense (Juz.) Holub in the territory of South Ural State Natural Reserve are presented. A. biarmiense represented by relict populations located in remote areas in in moss-lichen communities of mountain-tundra belt of the Urals, in some places descend into the mountain-forest belt. For most parameters, such as vegetative and generative areas lead coenopopulations located in mountain-forest belt. The greatest variability have parameters: number of generative shoots, number of leaves. Vital state of coenopopulations A. biarmiense varies in different ecotopes: five coenopopulations - prosperous, one - equilibrium, six - depressive. As a result of cluster analysis investigated coenopopulations A. biarmiense were divided into two clusters, combining coenopopulations mountain tundra and mountain-forest belt.
