Lichens (Lichenes) in the kanin-pechora subprovince of the arctic floristic region

摘要

The lichen flora of the Pechora river flood, Ortina river right-bank and middle part of the Bolvansky Nose Peninsula situated on the west of the Bolshezemelskaya tundra, and area near Peschanka Lake situated on the east of Malozemelskaya tundra are studied. The total list of lichens included 139 species. 38 species of lichens were recorded for the first time for Kanin-Pechora subprovince, including the rare species (Cladonia luteoalba, C.bellidiflora, Biatora sphaeroides, Hypogymnia bitteri, H.vittata, Parmelia sulcata, Peltigera elisabethae, P.venosa, Phaeocalicium compressulum, Ramalina sinensis, Varicellaria rhodocarpa). Significant impoverishment of lichen flora due to the influence of the oil-and-gas industrial objects and decrease in lichen shares in secondary communities during last 20 years were shown.
