Rare lichens, mosses, liverworts and fungi from the Republic Sakha (Yakutia), Russia

摘要

The Republic of Sakha (Yakutia) is situated in the north-east of Siberia. The area of Yakutia (3 103 200 km2) occupies one-fifth of the Russian Federation’s territory. In total 1984 species of vascular plants, 523 of mosses, 199 of liverworts, 703 of lichens, 911 of fungi and 2476 of algae are known in Yakutia. Among them 19 species of vascular plants, 6 of mosses, 8 of liverworts, 2 of lichens, and 2 species of fungi are included in the Red Data Book of the Russian Federation (2008). In this study all currently available information about locations of red-listed mosses, hepatics, lichens, and fungi on the territory of the Sakha Republic, is provided. Diverse climatic and edaphic conditions of Yakutia provide a wide range of ecological niches for the growth of species of different ecological requirements. Most of the rare species included in the Red Data Book of Russian Federation have narrow ecological amplitude. Majority of the species was recorded in mountain ecosystems on rocky outcrops, especially on limestone, at the banks of rivers and streams, and in old-growth boreal forests.
