MOSSES OF GOBI IN MONGOLIA

抄録

  The moss flora of Mongolian Gobi Altai and two adjacent localities in the Mongolian Altai is studied and analyzed. It includes 164 species and one variety of mosses belonging to 72 genera and 21 families. Most of species are restricted to the higher elevations in mountains where wet habitats are available and antropogenic influence is no so strong. However, about 15 species can tolerate really xeric environment, occurring on low rock outcrops in open desert and desert-facing, rocky foothills of mountains. The rather rich moss floras of two isolated sites provide evidence for a more diverse past vegetation in the Gobi area.
