Bryoerythrophyllum alpigenum (Bryophyta, Pottiaceae) confirmed in the moss flora of Poland, with a review of the nomenclatural issues associated with this species name


 
 
 Occurrence of Bryoerythrophyllum alpigenum (Jur.) P.C.Chen in Poland is confirmed. The species is known from a single record from the Western Tatra Mountains in the Polish Western Carpathians. A description and illustrations of the Polish material of this species is provided and its distribution mapped. Taxonomic and nomenclatural comments on B. alpigenum are presented and its global geographical distribution is reviewed. This species was first recognised as a variety, Didymodon rubellus var. dentatus Schimp., in 1860 by W. P. Schimper. It was subsequently described in 1882 by J. Juratzka as Didymodon alpigenus Jur., and its name should be ascribed to Juratzka alone, not to Venturi as suggested in Index muscorum and D. alpigenus Jur. is the basionym of Bryoerythrophyllum alpigenum. The epithet alpigenus appeared in the literature for the first time as Trichostomum alpigenum Venturi in Pfeffer’s work of 1869 dealing with the mosses of the Rhaetian Alps, but the name was not validly published under Art. 36.1, because Pfeffer did not accept it. Likewise, the name Didymodon alpigenus was not validly published by Venturi ten years later under Art. 38.1, because no description or diagnosis or a reference to a previously and effectively published description or diagnosis were provided. The current statistics of the moss flora of Poland is given. Since the publication of the catalogue of Polish mosses in 2003, some 17 species, one subspecies and three varieties of moss have been added to and two species were excluded from the moss flora of Poland, so currently some 715 species, nine subspecies and 90 varieties are known to occur in the country.
 
 

Changes in the moss (Bryophyta) flora in the vicinity of the Spanish Juan Carlos I Station (Livingston island, Antarctica) over three decades

There are very few long-term studies on Antarctic vegetation available, and very little is known of plant community changes over time in the Antarctic Peninsula area, an area itself subject to considerable change in recent decades. The vegetation of the South Bay area near the Spanish Station Juan Carlos I on Livingston island (South Shetland Islands) was extensively surveyed in the 1980s, and this study reports comparison of that survey with a new extensive survey carried out in the 2018/19 austral summer. A total of 38 species was found in the survey, an overall decrease in diversity, with eight previously recorded species not relocated including all representatives of the families Encalyptaceae (two species) and Hypnaceae (two species). One previously unrecorded species was found. Descriptions and discussion of each taxon recorded are provided, along with consideration of the possible causes of the changes observed.

Moss communities of xeric calcareous habitats in the southeastern United States: An assessment of compositional variation and distance decay

Moss floras of xeric calcareous habitats were studied at field sites in Florida, Alabama, Georgia, Tennessee and Kentucky. At each site, one study area was established, including open glade and wooded margin. A species inventory and a community composition investigation were conducted at each study area. Community composition was analyzed for ground-dwelling (soil and rock) and corticolous communities. Ground-dwelling communities were sampled with quadrats, and corticolous communities were sampled by examining trees along the margins. Presence/absence data from the complete species lists from the five sites were used to calculate Jaccard similarity indices among pairs of sites. The frequencies of species occurring in community samples were used to calculate Bray-Curtis similarity indices for ground-dwelling margin and corticolous communities. Jaccard and Bray-Curtis similarities were used in regression analyses to explore their relationship with geographic distance and climatic factors. The total number of species found at each 1 ha study area ranged from 32 to 35. Part of the flora at each site consisted of species common elsewhere in the region, but there were also species commonly associated with calcareous substrates, such as Pleurochaete luteola, Weissia jamaicensis, Orthotrichum strangulatum, Schistidium rivulare and Hyophila involuta. Regression analyses of pairwise similarities and geographic distances showed a strong non-linear correlation between distance and the Jaccard similarities, a somewhat lower correlation between distance and the Bray-Curtis similarities from ground-dwelling margin communities, and little correlation between distance and corticolous community compositions. Multiple regression analyses suggested significant correlations between community variation and temperature and in most cases weaker correlations with precipitation. Our results were notable in that the ground-dwelling community subset exhibited a pronounced distance decay but the corticolous subset did not. This finding suggests that in bryophytes characteristics associated with habitat fragmentation and substrate type have important effects on beta diversity.

MOSSES OF MOUNTAIN RANGES OF THE PECHORA-ILYCH STATE STRICT NATURE RESERVE (NORTH URALS, PECHORA AND ILYCH RIVER CATCHMENTS)

The results of studying the moss flora of the mountainous part of the unique European protected area – Pechora-Ilych State Strict Nature Reserve (coordinates of the bounding box around the core part of the reserve: 61.95697°N, 57.77589°E – 63.27388°N, 59.63549°E), listed as UNESCO World Heritage under the title Virgin Komi Forests, are presented. The combined (Pechora and Ilych river catchments) mountain moss flora includes 172 species from 78 genera and 33 families, which is almost a half of the reserve’s moss species diversity (348 species). It is shown that the moss floras of mountainous areas in the Pechora and the Ilych catchments demonstrate great similarity in the quantitative and qualitative features of the taxonomic structure. New data are presented on the occurrence of four rare species of mosses, listed in the regional Red Data Books of the Komi Republic and neighboring territories – Codriophorus fascicularis (protection status 2), Anomodon longifolius, Encalypta brevicollis and Lescuraea radicosa (protection status 3), and six species (Anomodon viticulosus, Encalypta ciliata, Kiaeria glacialis, Loeskypnum badium, Paraleucobryum longifolium, Pterigynandrum filiforme) in need of biological surveillance.

Новый список видов растений и лишайников России для программы Turboveg for Windows

A new species list of plants and lichens of Russia and neighboring countries has been developed for Turboveg for Windows, the program, intended for storage and management of phytosociological data (relevés), is widely used all around the world (Hennekens, Schaminée, 2001; Hennekens, 2015). The species list is built upon the database of the Russian website Plantarium (Plantarium…: [site]), which contains a species atlas and illustrated an online Handbook of plants and lichens. The nomenclature used on Plantarium was originally based on the following issues: vascular plants — S. K. Cherepanov (1995) with additions; mosses — «Flora of mosses of Russia» (Proect...: [site]); liverworts and hornworts — A. D. Potemkin and E. V. Sofronova (2009); lichens — «Spisok…» G. P. Urbanavichyus ed. (2010); other sources (Plantarium...: [site]). The new species list, currently the most comprehensive in Turboveg format for Russia, has 89 501 entries, including 4627 genus taxa compare to the old one with 32 020 entries (taxa) and only 253 synonyms. There are 84 805 species and subspecies taxa in the list, 37 760 (44.7 %) of which are accepted, while the others are synonyms. Their distribution by groups of organisms and divisions are shown in Table. A large number of synonyms in the new list and its adaptation to work with the Russian literature will greatly facilitate the entry of old relevé data. The ways of making new list, its structure as well as the possibilities of checking taxonomic lists on Internet resources are considered. The files of the species list for Turboveg 2 and Turboveg 3, the technique of associating existing databases with a new species list (in Russian) are available on the web page https://www.binran.ru/resursy/informatsionnyye-resursy/tekuschie-proekty/species_list_russia/.

RARE MOSSES OF THE KONDINSKIE LAKES NATURAL PARK NAMED AFTER L. F. STASHKEVICH

The moss flora of the Kondinskie Lakes Natural Park named after L.F. Stashkevich (Khanty-Mansi Autonomous Okrug - Yugra, Russia) currently in-cludes 114 species. Fifty-four species (47.4%) are rare for the natural park, of which eleven species, such as Dichelyma capillaceum, Dicranum septen-trionale, Sphagnum annulatum, S. mirum, S. subfulvum, S. tenellum, are rare for the Khanty-Mansi Autonomous Okrug and Western Siberia. The phytocenotic association and the frequency of oc-currence of the studied species was analyzed. The paper discusses the reasons for the high proportion of rare mosses in the park’s brioflora and the fea-tures of their distribution over the territory of the park.

Three new additions to the moss flora of Sri Lanka

Mosses (Phylum Bryophyta) comprise the most speciose group of bryophytes (liverworts, mosses, hornworts) and consist of about 13,000 species worldwide. Owing to its high level of topographic and climatic heterogeneity, the tropical island of Sri Lanka supports a luxuriant growth of mosses. Compared to other groups of plants in the country, mosses remain as a poorly researched group. Lack of proper taxonomic studies and scarcity of literature sources including locality details hamper further research in the field of bryology. Present study was carried out to explore the diversity of mosses in some selected localities of Sri Lanka. Fresh samples of mosses were collected from different localities including Horton Plains National Park, Loolkandura Conservation Forest, Kanneliya Forest Reserve and Badagamuwa Conservation Forest. Samples were observed for their morphological and anatomical characters using dissecting, compound and scanning electron microscopes. Specimens were identified following recent classification systems, using the most recent taxonomic keys, and monographs. The study identified three species records new to Sri Lanka including Brachymenium capitulatum (Mitt.) Kindb., Ctenidium pinnatum (Broth. & Paris) Broth. and Fissidens crassinervis var. laxus (Sull. & Lesq.) A. Eddy. Descriptions of these new species along with photo plates are provided. With the addition of 03 new records the total number of mosses recorded in the island increases from 572 to 575.

Patterns on geographical distribution and taxonomic similarity of mosses in the beech forests of Mexico

Studies on the distribution and taxonomic composition of moss floras in diverse types of vegetation and at a variety of geographical scales are useful for elucidating patterns of dispersal in space and time. Given this, the present contribution aims to (1) provide data on richness, habitat and geographical distribution of Mexican beech (F. grandifolia subsp. mexicana) forest mosses in the Sierra Madre Oriental (SMO), Mexico; (2) estimate moss species similarity among different beech forest areas in eastern Mexico; and (3) compare generic moss composition in temperate humid beech and cloud forests around the world. To do so, moss samples were obtained from Mexican beech forests and from the literature data for other regions. Jaccard's index was used to estimate floristic similarity among localities, and the distances between groups were represented by means of a dendrogram (UPGMA). The SMO beech forest moss flora in the state of Hidalgo contains 30 families, 54 genera, 71 species, and 4 varieties. The most representative families are Dicranaceae (10 species) and Pylaisiadelphaceae (6). Species richness is similar among localities, and floristic similarity is related to geographical distance. The most common substrates are epiphyte-lignicolous (20%), saxicolous (15.4 %), and lignicolous (7%). Most moss species in the beech forest of Mexico exhibit wide, Caribbean or boreal patterns of distribution. At the species and genus levels, floristic similarity is greater between closer localities while distant sites share a lower number of species (beech forests in Hidalgo) or genera (beech forests and cloud forests in various world regions), reflecting perhaps more heterogeneous environments with increasing distance between sites.
