The Liverworts of the Murmansk Region (North-West Russia): Providing an Annotated Checklist as a Basis for the...

An annotated list of liverworts of the Murmansk Region is compiled based on a critical compilation of publications and label data available in the information system CRIS (L.). It includes 210 species, 2 subspecies and 8 varieties, which is 59 species more than in the list of species published in 1982. Ten taxa were excluded through comparison with the previous list and later publications, due to misidentifications or new taxonomical treatments. Annotations for each species include the synonyms under which they were listed for the region; the category of threat in the Red Data Books of Europe, Russia and the Murmansk Region; links to the most representative publications on occurrence in each of nine accepted biogeographic provinces of the region; and at least one specimen number of the KPABG or INEP herbaria in the case of the absence of published data. In total, we provide 259 new records for different provinces based on herbaria KPABG (205 records) and INEP (52 records). Additionally, there are links to publications on the nucleotide sequence data of 149 specimens obtained for 82 species and for 1 variety from the Murmansk Region, including 14 specimens (11 species), published here for the first time. Species threatened in Europe, Russia and the Murmansk Region are discussed and future perspectives of liverwort study in the Murmansk Region are outlined.
