Patterns of bryophyte diversity in arable fields of Lithuania

The paper presents research data on bryophyte diversity in arable land throughout the territory of Lithuania. The bryoflora was analyzed regarding systematic structure and morphological forms, life-history strategies, mode of reproduction and frequency of species. Bryophyte diversity in arable fields of Lithuania was compared with that of Slovakia and the British Isles, which are positioned in different geographical regions of Europe. A total of 97 species of bryophytes of 25 families and 48 genera were ascertained. Dominance of acrocarpous mosses and thalloid liverworts, high representation of Pottiaceae, Bryaceae, Mielichhoferiaceae and Ricciaceae families as well as Bryum, Dicranella, Pohlia and Riccia genera, wide distribution of annual shuttles and ephemeral colonists, high reproduction effort of the species (frequent sporophytes and asexual propagules) were specific features of the bryophytes of the studied habitats as a result of adaptations to regular disturbances. The distribution of species into six frequency groups seemed to be uneven. The most abundant group of species with the lowest frequency (1–3 records) covered 53.6% of all species. The group contained about 90% of all many-year potential life span species recorded in the habitat. Species with short life span were distributed quite evenly throughout frequency groups. No regionally-specific species were ascertained in the studied habitat. Most of arable-land-specific species recorded in Lithuania is distributed throughout different regions of Europe

Bulgaria. Samokov Region, Rila Mountains, Rila National Park, N slopes of peak Deno, on granite slabs and scree, collected with occasional sporophytes, 42.19709°N, 23.60322°E, 2780 m a.s.l, 17 September 2019, leg./det. R. Natcheva s.n. (SOM 9811-B). This arctic-alpine species has a north Holarctic circumpolar distribution and this is the first report of Andreaea blyttii for SE Europe. It is its southernmost locality and extends its range further south in Europe. The Rila Mountains are the highest in the Balkan peninsula and A. blyttii was found near the highest summit (Mussala, 2925 m a.s.l.). In Bulgaria the genus Andreaea is also represented by A. alpestris (Thed.) Schimp. and A. rupestris Hedw., both of which occur in the Rila Mountains

During the examination of a collection made by the authors in 2009 in San Pedro de Atacama (Antofagasta Region, Chile) one specimen was identified as Bryum incacorralis Herzog, a moss not previously known from Chile (Müller, 2009) and easily confused with some species of Philonotis Brid. (Ochi, 1980). Comparison with the type material confirmed its identity (Holotype: Bolivia, Cochabamba: an Felsen der "Estradillas" bei Incacorral, 3000 m, Herzog s.n., JE! no. 04003475). Bryum incacorralis was first described by Herzog (1909) based on material collected in Cochabamba (Bolivia), and later recorded by Griffin (1977) and O'Shea (2010) from Venezuela. It is placed in the so-called sect. "Alpiniformia" within the genus Bryum which is characterized by the presence of ovate to ovate-lanceolate leaf shape, the costa ceasing just below the leaf apex, the very dense areolation of the leaf, and long, more or less clavate capsules (Ochi, 1980). This note constitute the first record of Bryum incacorralis from Chile, where the species was found in the highlands of the north part of the country, in San Pedro de Atacama, an arid high plateau placed at the east of Antofagasta, growing on soil between Laretia, at ca. 4000 m. Bryum incacorralis is a distinctive species characterized by small to medium sized plants, scarcely lustrous, with ovate-lanceolate leaves, not or hardily bordered, equally spaced through the stem, with an acuminate apex and an abruptly narrowed base; laminal cells hexagonal to short-rectangular, and a costa ceasing just below the apex. Chilean specimen is synoicous, with antheridia and archegonia mixed at the same gametoecium, with abundant filiform paraphyses longer than the sexual structures. In comparison with the type specimen, the Chilean sample is more robust, its leaves margin are little revolute, and the apex vary from mild to markedly abruptly acuminate, sometimes ending in a small mucro.Fil: Jimenez, Maria Soledad.
