The results of phytosociological research conducted on the fern vegetation of rock crevices and clefts of the Pamir-Alai Mountains in Tajikistan are presented.
2013; Nowak et al-, 2014a, b), focusing on the vascular plant vegetation of solid rock faces, fissures, rock clefts and ledges of the alpine and subnival zone of the Pamir-Alai Mts.
The relatively high diversity of ecological niches among rock habitats influences the considerable floristic richness and diversity of petrophilous fern vegetation in the Pamir-Alai Mts.
Even if the habitat conditions are comparable, and the vegetation is composed of closely related taxa, due to the considerable geographical distance between the Pamir-Alai and the Mediterranean basin, with many barriers between, there are different representatives of the same genera in phytocoenoses.
Vegetation of rock crevices of the montane and colline zones in the Pamir-Alai and Tian Shan Mts in Tajikistan (Middle Asia).
