The list of mosses known for Magadan
Region includes 434 species. It is compared to moss floras of other regions in
the Russian Far East. It is shown that in the north of the Russian Far East, Magadan Region is characterized by a heightened diversity
of mosses along with Kamchatka and Beringian Chukotka; the greatest
similarity in the moss flora is observed with these same regions. The compiled
summary table of species clearly demonstrates the latitudinal distribution of
moss species in the Russian Far East and the distribution by the floristic
regions within the Magadan Region. As a result of
sorting the summary table of species lists, in the moss flora of Magadan Region three large groups of species differing in
their predominant distribution in the Far East
were revealed: “cross-cutting”, “northern” and “southern”. The former
account for approximately 40%; the “northern” and “southern” groups have a
comparable number of species. More than half of “southern” species in Magadan Region are at the northern limit of their
distribution in the Far East. The locations of
the “southern species” are concentrated in the Okhotsk District. A list of
species that can be found in future is provided.
