Those from high-and mid-alpine habitats are low-growing and compact, yellow-green and have appressed leaves. Moreover, they produce abundant bulbils. Southern lowland plants are larger, very dark green, have more or less patent leaves, and bulbils are sparse or absent [2]. Such variation is treated differently by European botanists. According to Elven [3], this variation may be due to three possibilities: (i) H. selago represents a single undifferentiated species, (ii) it consists of a number of races or subspecies, or (iii) it consists of several species. Russian authors, however, have applied for some taxa to be elevated to the rank of species, e.g. H. selago, H. petrovii and H. arctica [4] or H. selago, H. appressa, and H. arctica [5,6]. The most recent western European treatments, based on a hypothesis of gradual divergence of races or species, recognize only one species, H. selago, consisting of two or three subspecies, namely, the temperate to boreal subsp. selago, a northern alpine-boreal to southern arctic subsp. appressa (not accepted by all authorities), and a northern arctic subsp. arctica [3]. Most northwestern European authors [2,7-9] recognise just two subspecies (H. selago subsp. selago and H. selago subsp. arctica) and tend to regard H. selago subsp. appressa as intermediate between selago and arctica. It is thus not accepted as a taxon and plants conforming to subsp. apressa are assigned to subsp. arctica. Such distinction is recognized in literature such as Flora Europaea [10], Flora Nordica [2] and the New Flora of the British Isles [11]. This last classification, namely, that H. selago consists of two subspecies, is the one adopted in the present paper. The subspecies arctica has a circumpolar distribution with a distribution range that includes both arctic and boreal zones. This subspecies has been recorded from Finland, Iceland, Norway, Sweden and the northern part of Russia. Solitary records are also known from Scotland [12]. Although H. selago is distributed throughout the Baltic countries, no data on subspecies arctica are known from Lithuania, Latvia and Estonia [13-15]. Furthermore, this subspecies is not recorded in the floras or plant lists of the neighbouring countries, Belarus [16] and Poland [17]. As a result, the southernmost localities known for this subspecies occur in the southern parts of Finland and Sweden. Its abundant production of bulbils is one of the characters used to distinguish H. selago subsp. arctica from H. selago subsp. selago. According to Naujalis [18] propagation of H. selago in Lithuanian populations is mainly by means of spores, not bulbils. However, mountain populations of this species in Poland are characterized by the presence of numerous vegetative propagules [19]. This paper characterizes the habitats of Lithuanian H. selago subsp. arctica (i.e. populations found outside and to the south of its typical distribution area). The main aim was to compare the habitats occupied by this subspecies with those in the northern part of its distribution range and to assess the possibility that H. selago subsp. arctica might also occur in other localities throughout Lithuania and its neighbouring territories. The influence of the distribution of the invasive moss Campylopus introflexus upon the frequency of H. selago subsp. arctica was also studied. Material and methods Study sites Huperzia selago subsp. arctica (Fig. 1) was recorded from two peatlands in Lithuania-Sulinkiai (Radviliškis distr.,

Grout ex H.A.Crum is recorded for the first time in Lithuania and it is its fourth discovery at a third locality in Europe. It was found for the first time in 2000 in Kamanos mire, the largest peatland complex in the northern part of this East Baltic country. Targeted investigations at this site in 2017 resulted in the discovery of 14 populations and it is apparently the largest and most abundant locality of the species in Europe. Splachnum pensylvanicum is briefly described and illustrated along with some taxonomic notes and a detailed description of its habitat requirements. The global geographical distribution of S. pensylvanicum is reviewed and mapped. It is a Euro-Eastern North American temperate species and deeply penetrates into the Neotropics at montane stations in Venezuela and SE Brazil in South America.

Frequency and abundance of the invasive moss species were evaluated according to the parameters of peat (pH, total nitrogen, phosphorus, potassium and organic matter), prevailing herb-layer species, percentage of cover of herb and tree layers, amount of litter, and time since the abandonment of the area. Campylopus introflexus was recorded in 68.7% of the investigated disturbed peatlands, of these, 63.8% had recently been managed. The cover of the invasive moss did not correlate with most parameters of peat, but it differed significantly among the plots (1) with different prevailing herb-layer species, (2) abandoned for different lengths of time, (3) with developed and undeveloped tree layer, and (4) with different pH.

Nearly half of them are rare in the country. 21 species occurring in anthropogenic habitats of Lithuania are of high conservation value. Possibility to conserve bryophyte species restricted to anthropogenic habitats is discussed.

It is colonized by bryophyte species adapted to regular disturbance by virtue of ephemeral lifestyles and compressed life-histories (Porley 2001). Various specialized asexual propagules are among the adaptation means (Whitehouse 1966, Nordhorn-Richter 1982, Shaw 1981). They form a persistent diaspore bank in the soil which is important in enabling the plants to persist unfavourable periods and rapidly colonize new ground when conditions become suitable (Bisang 1996; During 1979, 1995; During & ter Horst 1983; During & van Tooren 1988; During et al. 1988). Thus, arable land is a good study area for investigations of the diversity of species more frequently existing like diaspore bank in the soil. Nevertheless agricultural environments are often neglected by scientists regarding investigations of species richness (Zechmeister et al. 2003b). Although a wide range of investigations ...

This species is found in Italy only from Piemonte, Friuli Venezia Giulia, Calabria and, before 1950, Lombardia, Trentino-Alto Adige, Veneto, Emilia-Romagna, Toscana, Lazio and Sardegna (Aleffi et al. 2008). Neckera pennata was found at the base of a basalt breccia rocky wall within a beech forest (Fagus sylvatica L., referring to Fagetalia order), in a shady and fresh position. The outcrop is characterised by a discontinuous rupicolous community dominated by ferns (e.g.: Asplenium trichomanes L., A. septentrionale (L.) Hoffm. Cystopteris fragilis (L.) Bernh.\u2013 referring to the Asplenietea class) and mosses (e.g.: Ctenidium molluscum (Hedw.) Mitt., Amblystegium serpens (Hedw.) Schimp., Scorpiurium circinatum (Brid.)

At the beginning of the nineteenth century, he headed the Vilnius University Botanical Garden and lectured on botany at the Imperial University of Vilnius and the Vilnius Medical and Surgical Academy. It is a known fact that the Herbarium of Vilnius University (WI) contains Gorski’s largest collection of vascular plants. In 2016, the nineteenth-century collection of bryophytes in WI was analyzed. The analysis of handwriting on specimen labels, as well as their style, showed that more than half of the collection had been compiled by Gorski. The purpose of this study is to present Gorski’s reassembled bryological collection, which contains 729 specimens of bryophytes and is stored in the Herbarium of Vilnius University.

Bryophyte diversity and their patterns of distribution across different habitats were analysed. Species richness, biotal dispersity, Shannon's diversity and evenness indices were used for the evaluation of bryophyte diversity in various habitats, and the Jaccard and Bray-Curtis coefficients employed for comparisons of similarity. A total of 75 species were recorded for the territory (32 in grasslands and 62 in forests). Two species and three varieties were new to Lithuania, and four species and one variety were new to the Curonian Spit. Variations in bryophyte species richness and relative abundance of the most frequently encountered species were observed for fore-dune grassland, sand plain and dune ridges. Distinct species composition was ascertained for various substrata located in both dry and wet forests. The most frequent species occurring throughout the territory were those that favoured dry conditions and grow on different substrata, whereas obligate epixyles and epiphytes were rare. Species preferring full light were the most frequently encountered taxa in grassland habitats.

Naturally regenerating four disturbed peatlands from different regions of Lithuania were selected for the investigation. The aim of the study was to investigate invasive moss Campylopus introflexus cover effect on microbial communities. The peat under Eriophorum angustifolium, Polytrichum strictum and bare peat were sampled for the comparison. The abundance of microorganisms in sampling plots depends on the content of total nitrogen, potassium, soil organic matter and pH as well as on growing plants. In the peat under C. introflexus, the number of ammonifying and mineral N assimilating bacteria was significantly lower in comparison with other plants or bare peat. The results on fungi abundance in peat under C. introflexus allow to predict that the distribution of moss doesn't affect negatively the development of fungi. A total of 236 fungal strains belonging to 21 genera were isolated from the studied peat samples. Species from the Penicillium, Trichoderma and Mortierella genera dominated among them. The structure of microbial communities varied in separate peatlands and under various plants. However, all examined microorganism communities seemed to be able adapted to organic matter degradation.

An overview of the habitat diversity, environmental assessment of the area – occurrence of the habitats of European importance, their recent and future state, distribution of rare and endangered plant species in different habitats are introduced. Eighteen habitat types were indicated in Girutiškis Reserve. Woodland habitats dominate both on mineral soil and on peat. Open mires cover about 14 %. Girutiškis Reserve is a territory of high conservation value. Even 92 % of its territory is occupied by Natura 2000 habitats. The state of most Natura 2000 habitats is good and stable. There were registered 23 plant species included into the Red Data Book of Lithuania, among them 4 species are included into EU Habitat Directive Annex II and Bern Convention Annex I.
