Сравнительный анализ флоры мхов горных экосистем физико-географических регионов Уральской горной страны

Abstract

The data of a comparative analysis of the flora of mosses of Polar, Subpolar, Northern, Middle and Southern Urals are given. It is shown that the flora of mosses of the mountain ecosystems of the Urals consists of 592 species, 1 subspecies and 11 varieties belonging to 53 families and 173 genera. The flora of each of the five regions of the Urals is specific. On the Polar Urals, 371 species, 1 subspecies and 5 varieties were found, united in 47 families and 136 genera. The Subpolar Ural is the poorest in the musko-floristic relation. Here are found 349 species and 5 varieties of mosses belonging to 45 families and 130 genera. The richest flora of mosses of mountain ecosystems is found on the Southern Ural – 434 species and 5 varieties of mosses that belong to 49 families and 152 genera. A little lower is the diversity of musco-flora of Northern Ural: 432 species and 6 species, united in 51 families and 147 genera. There are 401 species and 7 varieties of mosses on the Middle Urals that belong to 50 families and 151 genera. Families are highlighted, which make the main contribution to the flora of mosses of the mountain ecosystems of the Urals. Rare species of the Urals and of each of its physical-geographical regions are designated, their chorological analysis is carried out, and the locating of rare species to substrates was analyzed.
