Bryoflora of mountain mires of Sub-Polar Urals

Abstract

The Bryoflora of mountain mires of Sub-Polar Urals within the Khanty-Mansi Autonomous District was studied in 2013-2015. The field work was conducted at Mt. Ner-Oika and in the upper course of the Puiva River (64° 27' - 64° 35' N, 59°35' - 59° 46'E). In total, 76 species of mosses were identified in the 24 mires surveyed. Most mosses have specific habitat preferences to different mire types, 5 species were observed almost in all types of mires: Warnstorfia exannulata, Straminergon stramineum, Sanionia uncinata, Pohlia nutans, and Pleurozium schreberi. A significant number of rare moss species were identified among the mires bryoflora (Dicranum laevidens, D. leioneuron, Loeskypnum badium Paludella squarrosa, Philonotis tomentella and others). Two species, Tayloria lingulata and Philonotis serotina were observed in the Khanty-Mansi Autonomous District for the first time.
