Features of lichenobiota distribution among landscapes of astrakhan region
Summary
The article presents the results of modern lichenological studies aimed at determining the distribution of the species composition of lichens across landscapes, including a survey of rare species in the Astrakhan region. The studies were conducted in the main landscapes between 2015-2024: Baskunchaksky: the vicinity of Lake Baskunchak, Mount Bolshoye Bogdo; landscapes of the Volga-Akhtuba floodplain and the Volga River delta. Eastern: ilmen-hillocks and the Baerovsky hillocks landscape. The lichen biota of the studied landscapes is represented by 21 species from 14 genera and 10 families. Of these, 10 are rare and protected species of lichens, six species (Circinaria esculenta (Pall.) Sohrabi, Circinaria fruticulosa (Eversm.) Sohrabi, Circinaria hispida (Mereschk.) A.Nordin, Savic & Tibell., Psora saviczii (Tomin) Follman & A. Crespo, Xanthoparmelia subdiffluens Hale, Seirophora lacunosa (Rupr.) Fröden.) are included in the Red Book of the Astrakhan region in 2014. Four species (Neofuscelia ryssolea (Ach.) Essl., Peltigera canina (L.) Wild., Caloplaca saxicola (Hoffm.) Nordin, Physcia clementei (Sm.) Lynge.) are recommended for inclusion in the regional Red Book of the Astrakhan region in 2024. The species is endangered and its numbers have been reduced to a critical level.
