Checklist of liverworts of the Pasvik State Nature Reserve (Murmansk Region, Russia)

Liverworts flora of the Pasvik State Nature Reserve (Pasvik Reserve) consists of 103 species, 5 subspecies and 2 varieties. We have summarized all available data on the diversity of liverworts of the Pasvik Reserve, including approximately 650 specimens collected by the authors. Calycularia laxa and Oleolophozia perssonii are reported for the second time from Murmansk Region. The territory is quite representative for protection and sustainable development of rare liverworts species – we found new localities for four red-listed European species (Barbilophozia rubescens, Haplomitrium hookeri, Lophozia ascendens and Nardia japonica), three liverworts included in the Red Data Book of the Russian Federation (Haplomitrium hookeri, Nardia breidleri and Oleolophozia perssonii) and 12 red-listed in the Murmansk Region

Checklist of mosses of the Pasvik State Nature Reserve (Murmansk Region, Russia)

The list of mosses of the Pasvik State Nature Reserve (Pasvik Reserve) consists of 197 species. Here we summarize all available data on the diversity of mosses of the Pasvik Reserve, including approximately 800 specimens collected by the authors. Stereodon pallescens and Tayloria serrata are in the Murmansk Region only known from the Pasvik Reserve. Seven species are red-listed in the Murmansk Region (Bryum cyclophyllum, Buxbaumia aphylla, Encalypta streptocarpa, Psilopilum laevigatum, Tayloria serrata, Tayloria splachnoides and Tetrodontium repandum). Tetrodontium repandum is included in the Red Data Book of the Russian Federation and Tayloria splachnoides is red-listed in Europe. The Pasvik Reserve gives a good possibility for the protection of rare mosses

A provisional checklist of mosses (Bryophyta) of Friendship Park (Finland)

We provide the first moss checklist of Friendship Park (Kainuu Region, Finland). Data from both own field collections and the literature are compiled. 164 species are listed in total, of which 79 are representing new species records for Friendship Park. Hedwigia mollis and Plagiothecium rossicum are reported for the first time from Finland. Most encountered moss species (75%) are widespread in Finland. Seven species occurring in Friendship Park are listed in the 2019 Red List of Finnish Species: Buxbaumia viridis (EN), Callicladium haldanianum (NT), Hamatocaulis vernicosus (NT), Schistostega pennata (VU), Sphagnum contortum (NT), S. inundatum (EN) and S. subnitens (NT). Further five species, Fontinalis dalecarlica (NT), Helodium blandowii (NT), Scorpidium scorpioides (NT), Splachnum ampullaceum (NT) and Tomentypnum nitens (NT), are included in the 2019 European Red List. The moss species diversity of Friendship Park is compared with that of the adjacent Kostomuksha Strict Nature Reserve (Russia). The total moss species richness of Friendship Park is assessed using nonparametric estimators. It is concluded that the moss species diversity of Friendship Park is relatively well known

Diversity and distribution of epiphytic lichens and bryophytes on aspen (Populus tremula) in the middle boreal forests of Republic of Karelia (Russia)

The distribution of epiphytic bryophyte and lichen species growing on aspen in the middle boreal forests was studied in southern Karelia (Russia). These forests varied in time-since-disturbance from 80 to 450 years. Two hundred twenty two species of epiphytes, including 178 lichens, 32 mosses and 12 liverworts, were recorded on 192 aspen trees in forests over 24 ha, in the Karelian part of the Vodlozero National Park, Kivach Strict Nature Reserve, Kizhi Sanctuary and Petrozavodsk City. Arthonia biatoricola, A. excipienda and Biatoridium monasteriense were collected in Karelia for the first time. Eighteen rare species (lichens Anaptychia ciliaris, Arthonia vinosa, Bryoria nadvornikiana, Chaenotheca gracilenta, C. stemonea, Lecidea albofuscescens, Lobaria pulmonaria, Melanelixia subaurifera, Nephroma bellum, N. laevigatum, Phaeocalicium populneum, Ramalina thrausta, Rostania occultata, Scytinium subtile, Usnea barbata, mosses Neckera pennata, Plagiomnium drummondii and liverwort Lejeunea cavifolia) listed in the Red Data Book of Republic of Karelia (2007) were found. Relationships between epiphytic lichen and bryophyte species richness and certain environmental variables (at different trunk heights above ground and time-since-disturbance) were evaluated. Lichens and mosses on aspen trunks often occupy different ecological niches. Cover and diversity of bryophytes was high on trunk bases, while the number of lichen species and their cover were higher at a height of 1.3 m above ground level. The total number of lichen species on aspen increased on average from 40 to 60 species per ha with increasing time-since-disturbance from 100 to 450 years. A stabilization in lichen species number was observed at about 200 years since disturbance. No significant correlation was determined between bryophyte diversity on aspens and the time-since-disturbance.

New national and regional biological records for Finland 11. Contributions to Bryophyta and Marchantiophyta 10

Ten species of mosses (Bryophyta: Entosthodon obtusus, Entosthodon ulvinenii, Eurhynchiastrum diversifolium, Hedwigia emodica, Hedwigia mollis, Hygrohypnum styriacum, Plagiothecium rossicum, Polytrichum perigoniale, Tortella alpicola and Ulota intermedia) are presented as new for Finland. Cephalozia lacinulata, previously considered to be regionally extinct from Finland, is reported to being found again. New records in biogeographical provinces for 67 species of mosses and 34 species of liverworts are listed. Finally, 6 occurrences in provinces are removed due to misidentifications or missing specimens

Biodiversity of a boreal mire, including its hydrographic network (Shichengskoe mire, north-western Russia)

The paper is based on the dataset whose purpose was to deliver, in the form of GBIF-mediated data, diverse materials on the biodiversity of a large mire, Shichengskoe mire (Vologda Region, north-western Russia), including its various mire sites and intra-mire water bodies. The dataset was based on our materials collected for two decades (from 2000 to 2021) in different parts and biotopes of the Shichengskoe mire and complemented by scarce data obtained previously by other researchers. The data contain materials on the diversity of Animalia (2886 occurrences), Bacteria (22), Chromista (256), Fungi (111), Plantae (2463) and Protozoa (131). Within the study period, the most detailed and long-term biodiversity studies were carried out for higher plants and invertebrates. On the other hand, the data on the composition of lichens, protozoa, algae, basidiomycetes, some groups of invertebrates and, to a lesser extent, lichens and vertebrates are far less comprehensive and require further substantial research efforts. The list includes occurrences from both the peatland (mire sites and mire margins different in typology) and the objects of the mire hydrographic network. In a standardised form, this article summarises both already published (mainly in Russian) and unpublished materials.The paper summarises the results of long-term research on the biodiversity of a boreal mire, including its hydrographic network. A total of 5869 occurrences were included in the dataset published in the Global Biodiversity Information Facility (GBIF, gbif.org) for the first time. According to the GBIF taxonomic backbone, the dataset covers 1358 taxa, including 1250 lower-rank taxa (species, subspecies, varieties, forms) and 108 taxa identified to the genus level. Several species found in the Shichengskoe mire, mainly belonging to Bacteria, Chromista and Protozoa, have never been listed in GBIF for the territory of Russia before. The overwhelming majority of occurrences and identified species came from the territory of Shichengskiy Landscape Reserve. Due to our work, this Reserve is now the most studied regional reserve in the Vologda Region with respect to biodiversity. By the number of revealed species, it is close to two federal protected areas: Darwinskiy State Nature Biospheric Reserve and National Park "Russkiy Sever"
