A working checklist of accepted taxa worldwide is vital in achieving the goal of developing an online flora of all known plants by 2020 as part of the Global Strategy for Plant Conservation. We here ...present the first-ever worldwide checklist for liverworts (Marchantiophyta) and hornworts (Anthocerotophyta) that includes 7486 species in 398 genera representing 92 families from the two phyla. The checklist has far reaching implications and applications, including providing a valuable tool for taxonomists and systematists, analyzing phytogeographic and diversity patterns, aiding in the assessment of floristic and taxonomic knowledge, and identifying geographical gaps in our understanding of the global liverwort and hornwort flora. The checklist is derived from a working data set centralizing nomenclature, taxonomy and geography on a global scale. Prior to this effort a lack of centralization has been a major impediment for the study and analysis of species richness, conservation and systematic research at both regional and global scales. The success of this checklist, initiated in 2008, has been underpinned by its community approach involving taxonomic specialists working towards a consensus on taxonomy, nomenclature and distribution.

An integrative study of expanded sampling of Apopellia species, including the topotype of Apopellia megaspora, made it possible to clarify the taxonomic position and distribution of the species of ...the genus. The ITS1-2 and trnL-F sequence data were obtained for 36 molecularly tested specimens, including the topotype Apopellia megaspora, that together with data previously deposited in GenBank, support the treatment of Apopellia as a separate genus and A. alpicola as a distinct species, as well as radically change the idea on the distribution of the species of the genus. It is shown that A. megaspora is an American-Asian species with single records in Europe, whereas A. alpicola is a West-American-Eurasian species widespread in western North America and occurring scattered in Eurasia. Both species occur in the mountains of western North America and south Siberia. A. endiviifolia is widespread in Europe, scattered in Asia and so far not confirmed for America. The expanded sampling of Apopellia spp. allows us to clarify the morphological features of the species of the genus, and microphotographs illustrate the more-important morphological features.

Nuclear ITS1–2 and chloroplast
trnL-F were sequenced for 21 taxa of
Lophozia s. str., two species of
Protolophozia, five species of
Schistochilopsis, three species of
Barbilophozia and
Obtusifolium ...obtusum. The topologies of phylogenetic trees for 49 taxa constructed from combined sequences of these regions by maximum parsimony, maximum likelihood and Bayesian methods are similar. The species of
Lophozia s. str., excluding
Lophozia sudetica, combine into two main clades and these contradict subdivisions of
Lophozia s. str. based on morphology. The species status of
Lophozia lantratoviae is confirmed, whereas
Lophozia austro-sibirica is almost identical to
Lophozia ventricosa var.
guttulata. The genus
Schistochilopsis is paraphyletic and occupies basal position to
Lophozia s. str., while
O. obtusum is clearly separated from
Schistochilopsis. A low level of divergence was found between
L. sudetica and
Protolophozia debiliformes, which are closer to
Barbilophozia than to
Lophozia s. str. Molecular divergence between geographically remote populations of
L. sudetica,
Lophozia silvicoloides and
Protolophozia debiliformis are low as opposed to those of
Lophozia polaris,
Lophozia pellucida or
Lophozia excisa. Consideration of the
trnL intron P8 region indels alone can adequately assign some clades revealed by tree building. A consensus secondary structure of the
trnL intron P8 region could not be inferred for taxa studied mainly due to high sequence length diversity originated from deletions.

The article provides relevant information on red-list species records of lichens, mosses, liverworts, and vascular plants from three Nature Monuments - Aikuaivenchorr Gorge, Kriptogrammovoe Gorge, ...and Juksporrlak. In total, 7 nationally (Nardia breidleri (Limpr.) Lindb., Encalypta brevipes Schljakov, Tetrodontium repandum (Funck) Schwägr., Arnica fennoscandica Jurtz. & Korobkov, Beckwithia glacialis (L.) Á. Löve & D. Löve, Cotoneaster cinnabarinus Juz., Papaver lapponicum (Tolm.) Nord.) and 33 regionally red-listed species were detected in the three nature monuments: 4 nationally and 11 regionally red-listed species in Aikuaivenchorr Gorge, 5 and 21 species in in Kriptogrammovoe Gorge, and 5 and 25 species in Juksporrlak, respectively. Two bryophytes (Metzgeria furcata (L.) Dumort and moss Grimmia elatior Bruch. ex Bals.-Criv. & De Not in Aikuaivenchorr Gorge as well as Grimmia alpestris (Schleich. ex F. Weber & D. Mohr) Schleich in Kriptogrammovoe Gorge) are new to the Khibiny Mts. One lichen species new to the Murmansk Region (Lecanora chloroleprosa (Vain.) H. Magn.) and several ones new to the Khibiny Mts. (Psora decipiens (Hedw.) Hoffm., Placidium rufescens (Ach.) A. Massal., Toninia squalida (Ach.) A. Massal.) were found in Juksporrlak. All the nature monuments of the Khibiny Mts. contribute significantly to biodiversity conservation, harbouring, respectively, 31 and 8 % of the protected species diversity of the Khibiny Mts. and the Murmansk Region at large.
In the Khibiny Mts. there are three nature monuments established in 1980, as suggested by staff of the Polar-Alpine Botanical Garden-Institute. These areas attracted the attention of botanists during ...the 20th and the 21st centuries; however, the description of their plant cover was absent in the literature. The article briefly describes the vegetation of the regional-level nature monuments Aikuaivenchorr Gorge, Kriptogrammovoe Gorge, and Juksporrlak, and provides preliminary checklists of the cyanoprokaryotes, lichens, mosses, liverworts, and vascular plants. All the three nature monuments are characterized by similar numbers of species belonging to different groups of plants and lichens, varying within 1/3-1/2 of their diversity in the Khibiny Mts. and 1/10-1/3 in the Murmansk Region at large. The nature monuments are frequently visited by tourists and therefore significantly affected by recreation. However, they are unique botanic areas essential in terms of biodiversity conservation in the Khibiny Mts. and the Murmansk Region.
The diversity and distribution of rare and threatened fungi, lichens, mosses, liverworts and vascular plants listed in the Red Data Books of the Murmansk Region (regionally red-listed) and Russia ...(nationally red-listed) within the Murmansk part of the Green Belt of Fennoscandia (GBF) are discussed. Records include 261 regionally red-listed species (8 species of fungi, 57 lichens, 31 liverworts, 55 mosses, and 110 vascular plants), i. e. 63.5 % of the total pool of red-listed species, and 17 nationally red-listed species (4 lichens, 5 liverworts, 1 moss and 7 vascular plants). Protected areas harbor 17 of the 30 nationally red-listed species known from the Murmansk Region, and 219 of the 411 regionally red-listed species, proving that protected areas inside GBF play an essential role in nature conservation in the Murmansk Region. The protected areas of greatest conservation significance for a majority of the analyzed groups are the Kutsa Nature Reserve (Zakaznik), Pasvik Stat Nature Reserve and Poluostrova Rybachy and Sredny Nature Park. For 43 red-listed species there are no records from protected areas inside GBF, including such species rare in the Murmansk Region as Peltigera lyngei, Carexatherodes, Botrychium lanceolatum, Lomatogonium rotatum, Draba nivalis, D. lactea, Flaviporus ci-trinellus, Skeletocutis lilacina, Chaenothecopsis fennica, Frullania tamarisci, Scapania simmonsii, Rhabdoweisia fugax, Tortula mucronifolia, Tanacetum bipinnatum, etc.). The priority steps to be taken to secure the preservation of rare and vulnerable species populations are reorganization of the Kutsa Nature Reserve into a Nature Park and alteration of the boundaries of the Poluostrova Rybachy and Sredny Nature Park.
The studies of cryptogams in the Green Belt of Fennoscandia (GBF) within Murmansk Region are reviewed and summarized. This territory, important in terms of biodiversity conservation, encompasses 13 ...operating protected areas, yet remains insufficiently studied. At first, since the mid-19th century, Finnish scientists played the key role in detecting the cryptogam biota of the GBF. They organized and carried out field surveys, as well as further taxonomic identifications and treatments of individual groups. Later, in the 20th century, intensive studies of cryptogams were associated with economic developments in the region, the establishment and activities of biological institutions in Murmansk Region: Polar-Alpine Botanical Garden-Institute and Institute of North Industrial Ecology Problems of the Kola Science Centre, Russian Academy of Sciences, science departments of strict nature reserves. At the beginning of the 21st century, Forest Research Institute and Institute of Biology of the Karelian Research Centre RAS became involved in the studies. The research mostly focused on the general biodiversity exploration of the territory, but at the same time some new taxa were discovered within various groups of organisms. An analysis of the current state of knowledge shows that algae and fungi in the GBF within Murmansk Region have been studied rather fragmentarily, and the known species composition does not reflect their real diversity. Lichens, mosses and liverworts of the territory have been revealed to a much greater extent. The Pasvik Strict Nature Reserve, the Ainov Islands of Kandalakshsky Strict Nature Reserve, the Nature Park The Rybachy and the Sredny Peninsulas and the regional nature reserve (zakaznik) Kutsa are the best studied areas, and the bulk of the cryptogam diversity of the GBF is concentrated there.
The annotated list of hepatics of Barents Island (Svalbard archipelago) was compiled based on the collections by Savchenko, literature data and Arne Frisvoll’s collection in TRH. A total of 35 ...species, three subspecies and four varieties are recorded for Barents Island. Fifteen taxa are listed as new for Barents Island and four taxa are listed as new for Svalbard, including Lophozia silvicola, Lophozia subapiculata, Preissia quadrata subsp. hyperborea and Lophoziopsis excisa var. elegans. A new combination Trilophozia quinquedentata var. turgida is made. Annotations to the species include distribution, description of habitats, and some morphological characteristics of the studied specimens. Peculiarities of the hepatic flora of the island and the distribution in Svalbard are discussed.
