    Opis:
    Based on results of the bryofloristic investigations carried out in 2006 along tourist roads and around mountain chalets the problem of bryophyte response to the tourist utilization of the summit region of Karkonosze Mts is discussed here. The hypothesis that introduction of cement as building material might have caused the income and spread of subneutral or basiphilous ruderal species in that naturally acidic region was formulated and tested. In result 45 species were found, of which the majority do not occur in natural sites in the Karkonosze Mts. Among them 20 species are convinced to be highly hemerophilous. Most of the found species were eurytopic, only 14 prefered subneutral or basic substrata. Many of them produced sporogonia, what indicates high reproduction potential. It seems that the phenomenon of synanthropisation is limited mainly to places in which cement (as mortar or concrete) has been used. The list of bryophytes found around all the anthropogenic sites and along the tourist roads in the summit region of Polish part of the massif with brief characteristics of their ecological preferences has been included.

    distribution
    Opis:
    The paper presents a brief review of published so far and recently recorded unpublished bryological data concerning the distribution in Poland of two neophytic (sensu Meusel 1943) mosses: Campylopus introflexus (Hedw.) Brid. and Orthodontium lineare Schwaegr.to estimate their current influence on native bryoflora. The data clearly indicate the constant spreading of these species towards the east, however, there is no direct evidence that they have been limiting the occurrence of native moss species. They are acidophilous species, so the acidification of the environment probably promotes their expansion. Maps of the most current distribution of Campylopus introflexus and Orthodontium lineare in Poland (in a system of ATMOS-grid squares) are provided, as well as a description of the first locality in Poland of another European bryo-neophyte species Leptophascum leptophyllum Mull. Hal.

    Opis:
    Based on geographical and ecological analysis of the present moss flora occurring in two contiguous glacial cirques Śnieżne Kotły (Western Karkonosze Mts.), the occurrence of 20 species representing arctic-alpine and subarctic-subalpine elements is discussed. The majority of (sub)arctic- (sub)alpine elements (70%) occurred sporadically or very rarely (no more than 5 records), which indicates their general threat. Nine historically recorded species of these geographic elements could not be retrieved during the recent survey, however four of the recently found species have not been found during the systematic survey of historical sites on the Czech, southern, side of Karkonosze Mts. This proves that the northern localization of Śnieżne Kotły cirques favours the survival of relict species. The question of relictness with respect to the Düll's phytogeographical characterization is discussed; only in ten of the (sub)arctic- (sub)alpine species the relict character could be considered as granted due to their present distribution range. The full list of the Śnieżne Kotły present moss flora with the brief characteristics of their ecological distribution has been included, first such attempt since 1930.

    Opis:
    The negative landform of sinkholes provides belowground level refugia for a high diversity of forest species compared to the forests on the surface of surrounding karst plateaus in southeastern China. Bryophyte diversity in sinkhole forests is also likely to be high. In this study, bryophytes of an underground forest sinkhole (UFS), and two forests (Forest Karst Mountain 1; FKM1) and (Forest Karst Mountain 2; FKM2) on the surface of the karst plateau were compared to understand the role of the sinkhole forest in the conservation of bryophyte diversity and the relationships between bryophyte diversity, environmental factors, and soil nutrients. Significantly more bryophyte taxa were recorded from the sinkhole forest (71 taxa, 36 genera, 23 families) than those in the forest on the plateau surface, which was the closest to the sinkhole (FKM1; 29 bryophyte taxa, 16 genera, 12 families), and even fewer bryophytes were found in the forest more distant to the sinkhole (FKM2; 22 taxa, 17 genera, eight families). Twenty-four liverwort taxa were collected from the sinkhole forest, two from the closest surface forest (FKM1) and none from the furthest surface forest (FKM2). Ninety-three percent of the bryophytes in karst mountain sinkhole were not found on surface forest. The diversity index trend was as follows: UFS > FKM1 > FKM2, and the evenness index trend was in the opposite direction as follows: UFS < FKM1 < FKM2. The beta diversity showed that the Jaccard index among the three forests was 0–0.25, reflecting a huge difference between the sinkhole forest and the two surface forests. Canonical correspondence analysis showed that light was the most important factor affecting the distribution of bryophytes in the sinkhole forest, while temperature and humidity were key factors for the distribution of bryophytes in the two surface forests. Further, soil parameters, namely, soil organic carbon, total nitrogen, total phosphorus, total potassium, alkali- hydrolyzed nitrogen, and available phosphorus changed gradually from UFS to FKM1 and to FKM2. The sinkhole forest, located in a landform with the unique negative topography enclosed by cliffs, and with a complex microenvironment, provides a natural refuge for bryophyte species in areas where forests have been negatively impacted by karst rocky desertification.

    Opis:
    In Poland, Hedwigia ciliata (Hedw.) P. Beauv., an obligatory epilithic moss species, has in recent years also been observed on the bark of trees. In this paper, we describe 25 recently identified sites in which epiphytic H. ciliata has been observed, and provide a plausible explanation to account for this phenomenon.

    Opis:
    Rare epixylic moss Buxbaumia viridis, which is one of the “Annex II” species of the European “Habitat directive”, has been recorded at 124 localities in the Czech Republic in course of the last 13 years. Most of them were discovered in the last five years following a dedicated search at both historical sites of occurrence and new localities with putatively suitable habitat conditions. The recent and historical area of occupancy and extent of occurrence are not obviously different, although most of the recent localities are concentrated in the Western Carpathians and the Hrubý Jeseník Mts. Surprisingly, only 38% of the localities are located in natural forest habitats, of which herb-rich and acidophilous beech forests were among the most commonly inhabited ones. The rest of occurrences were recorded in non-natural forests (habitats strongly influenced or created by man), particularly the coniferous forest plantations. Sufficient amount of decaying wood of the advanced decay stages, as well as sufficient and constant humidity are crucial prerequisites for the occurrence of B. viridis in both types of forests. True epixylic moss Herzogiella seligeri and the liverwort Chiloscyphus profundus were recorded as the most common associated species, while the rest of commonly co-occurring species were facultatively epixylic, ground or ubiquitous bryophytes; other specialized and rare epixylic mosses or liverworts were only rarely recorded. We also designed a potential distribution model for B. viridis based on the distribution of habitats most commonly occupied by the studied moss. Despite the simplicity of the model, its close match with the recent distribution in the Western Carpathians, the Hrubý Jeseník Mts. and Šumava Mts. supports its relevance for the real distribution of B. viridis.
