Сyanoprokaryotes, lichens and liverworts of Ainovy islands, Kandalaksha nature reserve (Murmansk region)

The study conducted on Ainovy Islands (Kandalaksha State Reserve) revealed 6 species of cyanoprokariots, 14 species of liverworts, and 100 species of lichens. 7 species of lichens (Absconditella lignicola Vezda et Pisut, Lecidea lapicida (Ach.) Ach., Lichenomphalia umbellifera (L.: Fr.) Redhead et al., Porpidia glaucophaea (Korb.) Hertel et Knoph, Rhizocarpon leptolepis Anzi, R. polycarpum (Hepp) Th. Fr., Verrucaria striatula Wahlenb.), one type of liverworts (Lophozia savicziae Schljakov), and 11 species of cyanoprokaryotes are found at the Kandalaksha State Nature Reserve for the first time. Lichen Absconditella lignicola is new to Murmansk region. Species’ diversity of the studied groups resulted from the small size of the territory, low diversity of ecotopes, and tough competition with higher plants. On the other hand, diversity of the species is caused by the negative ornitogenic impact.
