Abstract Studies on epiphytic bryophyte species richness and diversity in various urban-use complexes in Wroclaw (excluding urban forests) were conducted in 2013-2016 to check the research hypothesis that, in spite of the observed phenomenon of return of bryophytic epiphytes to cities, urban parks still favor species richness and the diversity of bryophytic epiphytes in built-up areas. Epiphytes (38 species) were recorded in all distinguished urban-use complexes but with strongly differentiated frequency, and 64% of all the trees colonized with epiphytes were situated either along streets or inside urban green areas (32% in each). It was shown that the highest species richness (89% of all the species found), bryophyte total coverage and values of the diversity indices referred to the latter complex. 20 species revealed preferences to occur mostly or exclusively on trees situated in urban parks. The second urban-use complex, which visibly affected the distribution of epiphytes, was the complex of streets; Tortula muralis occurred only on trees along streets and six other species occurred more frequently in these complexes than in others: Orthotrichum diaphanum, O. pumilum, O. pallens, Ceratodon purpureus, Syntrichia virescens, Bryum argenteum. In general, epiphytes – which were recorded on more than 20 trees – colonized a large number of phorophytes, from 12 to 33. They also showed some tendencies to occupy trunks of some host tree species more frequently than others. Detailed data are provided.

A study of the bryophyte of Marmore Waterfall Natural Park a very peculiar territory for its geological, biogeographical and bioclimatic traits, was carried out. The reported data were collected in the valley area of ‘Parco Fluviale del Nera’ Regional Park, where the waters are flowing and the humidity of the rocks is oozing. Research led to the identification of 101 taxa of bryophytes (21 liverworts and 80 mosses), among which two liverwort and 10 moss species are new records for the Umbria region, while four are confirmed. The study offers new outcomes on neglected aspects of the flora of central Italy and represents a considerable improvement of the floristic, biogeographical and ecological understanding of its bryophytic component. Additionally, the area turn out to be significant from the conservation point of view both nationally and internationally considering that it harbours high diversity of bryophytes species among which many rare, threatened and interesting species occur. Eighteen species of conservation interest in Italy are recorded during the latest investigation (all in category NT – near threatened). Additionally two species that are considered data deficient in Italy are present in the researched area (Conocephalum salebrosum and Fissidens curvatus). Also, there is a small populations of a species vulnerable (Marchantia paleacea), endangered (Bryum calophyllum) and data deficient (Fissidens curvatus and Barbula bolleana) in European scale.

Bryophytic fossil remains in the Permian Gondwana formations are extremely rare. The rarity of fossil bryophytes is generally attributed to their delicate nature and small size of the plants. Fossil bryophytes so far reported are few as compared to vascular plants but they have been adequately recorded to indicate early existence of mosses and liverworts. It is also likely that bryophytes have just not been recognized in ancient sediments by palaeobotanists and they may not be so rare as are believed today. Most of the fossil specimens reported from India as bryophytes are either doubtful records or unidentifiable up to generic level, Indian Permian reports are considered doubtful while Triassic and younger records are not so meagre and are reasonably well reported.
It is for the first lime a good assemblage of bryophytes has been recovered from the Early Permian sediments of India as impressions along with the typical Glossopteris flora. Both the groups Hepaticae and Musci are represented by newly designated form genera and species. The assemblage is represented by an indeterminate genus - Bryothallites talchirensis, hepatic genus- Hepaticites umariaensis, and three moss genera- Talchirophyllites indicus, Saksenaphyllites saksenae and Umariaphyllites acutus. Remarks on the naming of the fossil bryophytes, their probable possibility of preservation, spore distribution, probable habitat and evolutionary aspects also have been given and discussed.

Although nearly 85% of the bryophytes of the known flora of British Columbia show wide world distributions, they, plus the remaining 15% confined to western North America, segregated into at least eight distinguishable patterns. These patterns have been shaped by the coincidence of climate, historical events, substratum, and topography and have been altered more recently through anthropogenic disturbance. The distribution patterns form the basis for the bryophytes that characterize the biogeoclimatic zones. Lists of these bryophytes are provided for the 12 biogeoclimatic zones recognized for British Columbia by V. J. Krajina. Distribution maps are provided for 16 representative species. Other applications of bryophyte ecology in forestry practice include site evaluations, nutrient cycling, and successional interpretation.

Genus Hyophila Brid.; a moss belonging to subfamily Barbuloideae, family Pottiaceae is represented by 7 species in India; out of these, three species: H. involuta (Hook.) Jaeg., H. rosea Williams and H. comosa Dix. et P. Vard. occur in Central India. Earlier H. rosea alone was reported from Pachmarhi Biosphere Reserve (PBR) but during floristic studies of bryophytes of PBR, which is well known for its biodiversity and is rich in bryophytic vegetation, H. involuta has been encountered for the first time. This taxon has been earlier reported from several other localities and shows wide distribution in India in Bengal, Bihar, Orissa, Arunachal Pradesh, Upper Assam, South India and Western Himalayas etc. H. involuta is characterised by dioecious plants, erect dark green habit and radiculose stem (5-18 mm in size). Leaves are oblong, spathulate, carinate with percurrent costa, 1.8-2.8 mm x 0.56-0.86 mm, seta erect, capsule cylindrical with beaked operculum. Peristome is absent and spores are small, brown coloured, spherical, 8-12 µm in diameter. The species is distributed in various localities of PBR: Tamia Valley, Jambu Dweep. Near Police Training School, Near Forest Office, Pandav Caves and Bee Fall. H. involuta closely resembles with H. rosea which occurs in the same vicinity, in leaf size and shape, leaf cells and shape of capsule; however, it differs in its radiculose habit, uniform leaf arrangement, longer seta and smaller spores from the latter species.

Bryophytes are a group of plants generally with small sizes and spores as generative reproduction. There are three main groups of Bryophytes: liverworts or hepatics (Marchantiophyta), mosses (Bryophyta), and hornworts (Anthocerophyta). They are found in almost all ecosystems. Ecopark Cibinong Science Center-Botanical Garden (CSC-BG) is a lowland ecosystem protection area located in industrial cities. The bryophytes species that were carried out in 2009 and 2010 are inadequate. Re-exploration activity was carried out from June 2018 until January 2019 in all blocks of Ecopark. This study aims to report an update of bryophytes data in Ecopark. A total of 20 species of bryophytes were found in this research. Fissidens is the most common genus of bryophytes. There are 11 species of bryophytes and 9 species are new data records for Ecopark CSC-BG. This study updated bryophyte diversity data from Ecopark CSC-BG in 2009 and 2010, resulting in the discovery of 30 species (27 species mosses, 3 species liverworts), including 10 species not found in previous studies. There are no hornworts found in Ecopark CSC-BG.

The article gives a detailed description of the epixylic component of bryoflora of the Polesye Region on the terri-tory of Belarus, Russia and Ukraine. According to the results of a long-term comprehensive study of the Polesye bryocomponent, 468 species of bryophytes from three divisions have been recorded to date: Anthocerotophyta, Bryophyta, Marchantiophyta. On rotting and decaying wood, 159 species were identified, including 52 species belonging to the division Marchantiophyta, 107 – Bryophyta. The most representative in terms of species diver-sity are the family of liverworts Scapaniaceae, Cephaloziaceae, Calypogeaceae, Aneuraceae and Lophocoleace-ae, mosses – Brachytheciaceae, Amblystegiaceae, Dicranaceae, Hypnaceae and Mniaceae. The distribution of bryophyte species depending on the degree of decomposition of wood is shown, the forms of growth of bryophytes are considered, and hydromorphs are analyzed. An annotated list of bryoepixyls of the Polesye Region has been compiled. The systematic position, main synonyms, growing conditions, distribution in regions, ecological features, and occurrence are indicated for each species.

The paper records palynofossils from the dark grey shales/clays (inliers) exposed at Belkher Village, north of Ellichpur town in Maharashtra. The assemblage contains 41 species assigned to 22 genera and is characterised by pteridophytic and bryophytic components, viz., Callispora potoniei, Contignisporites glebulentus, Murospora, Triporoletes reticulatus, Coptospora kutchensis, Cooksonites cf. C. rajmahalensis, etc. The prominence of Callialasporites followed by Podocarpidites, Alisporites and Araucariacites is noteworthy. The assemblage is comparable to the palynozones-D of Rajmahal Hills, the assemblage recovered from Sivaganga area of Cauvery Basin, and Dharesi nala section of Bhuj Formation, Kutch Basin, which are assigned a Neocomian-Aptian age. The presence of spore-pollen, algal or fungal entities suggests freshwater conditions during deposition.

Epiphyte diversity as well as distribution and composition of epiphytic biomass was investigated in two lowland and two montane rain forests in Ecuador. Species numbers of epiphytes per tree were slightly higher in the montane (22–41 in Los Cedros, 33–54 in Otonga) than in the lowland forests (9–43 in Yasuni, 19–32 in Tiputini), however differences were not significant. In contrast, some epiphyte families did show significant altitudinal differences. The total epiphytic biomass per branch surface decreased from the centre of the crown to the periphery, and was generally higher in the montane (6.0 kg m−2 on central branches in Los Cedros, 1.8 kg m−2 in Otonga) than in the lowland forests (1.3 kg m−2 in Yasuni and 1.8 kg m−2 in Tiputini). Especially, dry weight of bryophytes and dead organic matter was higher in the mountains. In contrast, the biomass of green parts of vascular epiphytes on central branches was about the same in all four forests (0.4–0.6 kg m−2). A comparison with literature data from other study sites of tropical moist forests supports the observation that biomass of vascular epiphytes does not significantly change with altitude. It is discussed, that the high bryophytic biomass in montane compared to lowland forests is a major reason for differences in humus biomass between these forest types.

The number of bryophyte species from Maranhão has increased considerably in recent years due to new studies, with the frequent publication of new occurrences for the state. Effort is needed to organize and update the names to create an updated list of bryophyte taxa for the state of Maranhão based on published bibliographic surveys and reanalysis of collections. Here we provide an updated checklist of bryophytes of Maranhão as well as an assessment of the richness and taxonomic composition of the species and their phytogeographic distribution in relation to other Brazilian states. A total of 3727 collection records were analyzed, resulting in 269 species distributed in 110 genera and 43 families. The most representative division was Bryophyta with 151 species, the richest family was Lejeuneaceae (70 spp.), and the richest genus was Fissidens (24 spp.). One species—Ceratolejeunea maranhensis, from the Amazon domain—is endemic to Maranhão and eight are endemic to Brazil. The number of species found in this study places Maranhão in the thirteenth position among the Brazilian states in terms of diversity of bryophytes, revealing the importance of Maranhão as a center for the study and conservation of Brazilian bryofloristic diversity.

Lumut dikoleksi dengan metode transect-line pada 6 titik tepi jalan dan jelajah bebas pada 3 taman di permukiman tersebut Jakarta Selatan. Pengamatan karakteristik morfologi dan anatomi lumut dilakukan dengan penilaian kualitatif dan kuantitatif. Berdasarkan hasil penelitian terdapat 2 divisi lumut, yaitu Bryophyta (lumut sejati) dan Marchantiophyta (lumut hati) di lokasi penelitian. Bryophyta terdiri dari 6 famili, 9 genus, dan 16 spesies. Sementara itu, Marchantiophyta terdiri dari 2 famili, 2 genus, dan 3 spesies. Pottiaceae merupakan famili dengan jumlah spesies terbanyak ditemukan, yaitu 5 spesies. Fissidens biformis adalah spesies dengan jumlah sampel terbanyak. Lumut tersebut ditemukan pada substrat tanah, batu, dan batang pohon. Kisaran luas tutupan lumut yang ditemukan yaitu 2–100%. Karakteristik seperti ukuran tubuh yang kecil, bentuk hidup, bentuk daun, ornamentasi pada permukaan daun, modifikasi sel daun, serta keberadaan sporofit atau gemma diduga mendukung lumut beradaptasi di lingkungan urban.AbstractSettlement is one of urban green open spaces in Jakarta. One of the plant groups found in the open green spaces is the bryophytes. The presence of bryophytes in the settlement areas indicates the ability of bryophytes to survive in a disturbed environment. This study aims to determine bryophytes species and their characteristic in the settlements area of South Jakarta. Bryophyte collected by transect-line at 6 sites of roadside and broad survey at 3 sites of park. The morphological and anatomical characteristics were observed with qualitative and quantitative assessments. Mosses and liverworts are groups that found in study sites. The mosses consists of 6 families, 9 genera, and 16 species. Meanwhile, the liverworts consists of 2 families, 2 genera, and 3 species. Pottiaceae is has the highest species richness in the location. Meanwhile the highest number of samples was Fissidens biformis. The bryophytes were attached in the soil, rock, and tree trunk. The coverage of bryophyte is about 2–100%. Characteristics such as small body size, life-forms, leaf shape, the ornamentation on the leaf surface, modified leaf cells, and the presence of sporophyte or gemmae are thought to support the adaptation of bryophyte in urban environments.

The article presents data on the diversity and substrate groups of bryoflora of the Znesinnya Regional Landscape Park (Znesinnya RLP), located in the city of Lviv (Western Ukraine). Based on field research carried out in the period 2015-2018 and analysis of herbarium collections, an inventory was made of the bryoflora of the Znesinnya RLP. A total of 113 species of bryoflora belonging to 66 genera, 35 families and 2 divisions are presented from the investigated area. Of these, 105 species are members of the division Bryophyta and 8 belong to Marchantiophyta. Six regionally rare species of bryophytes have been recorded, namely Pellia endiviifolia, P. epiphylla, Encalypta streptocarpa, Fissidens exilis, Cirriphyllum crassinervium and Sciurohypnum starkei. With regard to substrate preferences, epigeous species of bryophytes predominated and accounted for 89.0% of the total number of species. The largest proportion of bryophytes occurred on bare soil (46.0%), while 36.3% and 25.7% species were found on soil among herbaceous vegetation and on soil with gravel, respectively. Stony substrates were colonized by 42.5% of bryophyte species, with 19.5% of species occurring on artificial stony substrates. In addition, 24.8% of the species belonged to epixils inhabiting old stumps and logs of varying degrees of decay, and the same proportion was represented by epiphytic species of bryophytes. The smallest proportion (10.7%) of bryophytes was confined to water bodies and swampy ecotopes.

Determining whether epiphytic bryophytes have ecological preferences for woody plants remains difficult. Here, our primary aim in developing the torus-translation test is to evaluate the associations between epiphytic bryophytes and woody plants at the species, genus, or family levels in a 100 m × 100 m forest dynamics plot in a temperate, deciduous broad-leaved forest (China). We collected all the epiphytic bryophyte species on woody plants and recorded the woody plant species in the 1-ha plot in 2020. All the epiphytic bryophytes on the trees from the ground level up to 2 m were collected. We recorded 988 epiphytic bryophyte specimens belonging to 61 species in 254 woody plants. The Torus-translation test showed that 93.44% (57/61), 93.44% (57/61), and 98.36% (60/61) of the bryophyte species were significantly positively associated with the family, genus, and species of woody plants, respectively. A total of 317, 563, and 857 significant positive associations concerning the family, genus, and species of the woody plants were observed among the 61 examined bryophyte species. In addition, few significant negative associations were identified regarding the family, genus, and species of woody plants. More rare bryophyte species were positively correlated with woody plants than dominant bryophyte species. Our study demonstrates that most epiphytic bryophytes exhibit ecological habitat preferences for woody plants. These observations highlight the importance of the species composition of woody plants with respect to the maintenance of epiphytic bryophytes’ diversity. Epiphytic bryophytes’ growth preference for woody plants, especially rare bryophyte species, should be considered in the process of bryophyte diversity conservation in temperate, deciduous broad-leaved forests.

Der volle Inhalt der QuelleAnnotation:
Background: Mexican botanists were not involved in bryophyte research fifty years ago; only four small floristic contributions were published between 1942-1958.
Questions: What has been learned in the last fifty years? How many bryophytes are there in Mexico? What are the contributions by Mexican scientists?
Studied species: Bryophyte flora.
Study site and dates: Mexico, between 1942-2021.
Methods: Bibliographic compilations were used to revise the status of bryophyte research in Mexico. Data for the last fifty years cited there and in an updated version of Latmoss served to determine the current knowledge of Mexican bryophytes as contributed by Mexican scientists. No thesis research was considered unless published in a scientific journal.
Results: There are 16 species of Anthocerotophyta, ca. 600 of Marchantiophyta, and 997 Bryophyta in Mexico. At least seven phytogeographic elements are represented: Northern, Meso-American, Caribbean, Southern, Wide distribution, and Endemic. Highlights of Mexican research include the discovery of Hypnodontopsis sp., a Miocene amber fossil from Chiapas, identification of heavy metals deposits in urban mosses in Mexico City and Toluca, determination of chloroplast and mitochondrial genomes of Pseudocrossidium replicatum, and the potential use of recombinant proteins from Physcomitrella patens.
Conclusions: Taxonomic and floristic studies should be continued along with the bryological exploration of the country. Conservation is urgent, but studies of drought tolerance, air pollution, climate change, and potential uses in medicine require support and collaboration from other scientists.

The aim of the present study is to recognize the utility of the bryophyte community’s structure in the assessment of soil condition in heavy metal-polluted, dry grasslands. The study plots are examined with respect to bryophytes; vascular plants; concentrations of Zn, Pb, Cd, and As in the soil; total nitrogen and organic carbon content in the soil; and soil pH. The results show that both bryophyte species richness and composition greatly depend on soil chemical characteristics, including heavy-metal pollution levels and soil pH. Three groups of species are distinguished: (1) species sensitive to pollution growing on acidic soils, (2) nonspecific species inhabiting a wide spectrum of heavy metal-polluted sites, and (3) species preferring polluted and alkaline soils. Our study reveals a gradual replacement of the bryophyte species alongside increasing soil pollution and alkalinity. This proves that bryophytes are highly responsive to soil factors and the changes in bryophyte composition may indicate the soil condition of a certain site. Furthermore, high concentrations of heavy metals in the soil and an alkaline pH positively affect bryophyte species richness. Consequently, such sites could be considered as biodiversity hotspots for terrestrial bryophytes in post-industrial landscapes.

Bryophytes are one of the main resources for bird nest construction; however, studies are limited and have been oriented to preliminary species lists. We evaluated for the first time in Ecuador the changes in the richness and composition of bryophytes in 17 nests of the species Myadestes ralloides and Catharus fuscater, of the family Turdidae. The presence/absence of bryophytes was recorded in each nest. A total of 25 bryophyte species were recorded (13 mosses and 12 liverworts). The most frequent species in the nests of the two species were the mosses Thuidium tomentosum and Meteoridium remotifolium and the liverworts Trichocolea flaccida and Frullania peruviana. The results indicated that bryophyte species’ richness and composition did not differ between the nests of the two studied bird species, because they select similar bryophyte species for nest elaboration. In general, our study showed that for the two species of birds of the family Turdidae, mosses and liverworts are key components in the elaboration of nests both internally and externally. On the other hand, we would suggest that further investigations should focus on analyzing the relation between bird nests and bryophyte phytochemistry, as well as the functional traits of bryophytes.

Corticolous bryophytes, that is, mosses and liverworts that inhabit tree trunks, represent an important component of plant diversity in temperate ecosystems, but little is known of their ecology in managed forests. In this study, we quantified community composition and habitat differentiation of corticolous bryophytes in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) plantations subjected to experimental thinning and fertilization treatments. Twenty-four bryophyte species were recorded in a sample of 480, 225 cm2 quadrats on 60 tree trunks. All moss species and obligately epiphytic liverworts (those with a primary habitat preference for tree trunks) showed highest cover values on south and west exposures. In contrast, facultatively epiphytic liverworts occurred only at the tree base, and mainly on north and west exposures. Pairwise correlations among species cover values were nearly always positive, and cover of the most abundant species, Isothecium myosuroides, was also positively correlated with local species richness of other bryophyte taxa. These patterns suggest that competitive interactions among bryophyte species are not strong in this community. There was little evidence for fertilization or thinning effects on total bryophyte cover or species richness. However, analyses of community composition and species-specific responses indicated significant negative effects of thinning on some bryophyte species. Observed patterns of habitat differentiation, interspecific associations, and treatment responses suggest that stand hydrology and microclimate are of primary importance in determining the distribution and abundance of corticolous bryophytes in managed forests.Key words: corticolous bryophytes, liverworts, mosses, nitrogen fertilization, plant diversity, silvicultural thinning.

The study of elevational patterns is a valuable method for inferring the influence of the climate and other variables in the regional distributions of species. Bryophytes are ideal for revealing different environmental patterns in elevational studies, since they occur from sea level to above the tree line. Taking advantage of the long elevational transect of Pico Island and the use of standardized survey methods, our main aims were: (1) to identify and characterize the alpha and beta diversities of bryophytes across the full elevational gradient (12 sites of native vegetation, ranging from 10 to 2200 m above sea level [a.s.l.]); (2) to detect the ecological factors driving bryophyte composition; (3) to identify bryophytes’ substrate specificity; and (4) to check the presence of rare and endemic species. The identification of 878 microplots yielded 141 species (71 liverworts and 70 mosses), almost half of those known to occur on Pico Island. The bryophyte species richness followed a parabolic unimodal pattern with a mid-elevation peak, where the richest native forests occur. A canonical correspondence analysis (CCA) of the bryophyte composition and explanatory variables revealed the effect of the elevation, precipitation, disturbance, richness of vascular plants and bark pH in explaining bryophyte compositions at regional levels. Very few species of bryophytes showed substrate specificity. Pico Island’s elevational gradient could be an asset for studying long-term changes in bryophyte species composition and alpha diversity under global change.

Background: Mexico has an extensive record of vascular plants that are used by humans and associated with traditional ecological knowledge (TEK). However, for non-vascular plants like bryophytes, there is no consensus on how many and which species have any TEK associated with them.
Questions: How many bryophyte species are used by humans in Mexico? What TEK is associated with them? Why is it important to document ethnobotanical information on bryophytes?
Studied species: Bryophytes sensu lato.
Study site and dates: Mexican territory. Time span covered by the studies reviewed was from 1552 to 2020.
Methods: Information in published materials, repositories, and personal fieldwork records were used to build a database on bryophyte taxa associated with some TEK in Mexico.
Results: According to available data, the bryophyte flora with some associated TEK in Mexico includes 36 species belonging to 30 genera and 23 families. The main use is ceremonial, although craft, environmental, medicinal, and ornamental uses are also reported.
Conclusions: This study updates the number of bryophytes used as non-forest timber resources. Ethnobotanical records for Mexico are among the highest in countries that use bryophytes in human enterprises.

Epiphytic bryophytes are important components of forest ecosystems and play important roles in maintaining biodiversity and ecosystem function. However, the main factors driving epiphytic bryophyte diversity remain unclear. We collected the tree epiphytic bryophytes from a one-hectare plot within a temperate deciduous broadleaf forest (China). Canonical correspondence analyses and Mantel tests were used to establish linear regression models and thus dissect the effects of environmental variables (topography, light and bark physicochemical properties) on the species diversity, functional diversity, and phylogenetic diversity of epiphytic bryophytes. The relationship between environmental variables and epiphytic bryophyte diversity was analyzed using piecewise structural equation modeling. Results showed that the physicochemical properties of the bark directly influenced the species diversity and phylogenetic diversity of the epiphytic bryophytes. The physical and chemical properties of bark also indirectly affected the functional diversity of the epiphytic bryophytes. Elucidation of the factors driving epiphytic bryophyte diversity provides insights into their conservation.

Bryophilous fungi associated with two bryophyte species in the region of delta in Tamil Nadu that is, the mosses of Polytrichum commune and Bryum capillare (Ptychostomum capillare) mosses were studied during the winter season. These bryophytes were Desiccation-Tolerance Bryophytes plant (DTB), the ability to lose virtually all free intracellular water and then recover normal function upon rehydration is one of the most remarkable features of bryophytes. Our aims were to identify bryophilous fungi/ endophytic fungi using morphological taxonomy, to explore richness and estimate species frequency in two bryophytes, Polytrichum and Bryum in delta region of Tamil Nadu. We collected two bryophyte samples at old building wall, bricks localities on delta region. We thus identified 32 endophytic fungi species were isolated from these bryophyte plants tissues. In total, 32 endophytic fungal strains belonging to Ascomycetes (04), Coeleomycetes (02), Hyphomycetes (20), sterile forms (02), Yeast like strains (02) and Zygomycetes (02) taxa were obtained. Thus species RPO and diversity index suggest that our study still underestimate endophytes diversity because it does not provide complete samples. These results recommend the presence of a diverse range of fungal species even in a very limited area, and those bryophytes fungal diversity in this Desiccation-Tolerance environment. To our knowledge, this is the first report of endophytic fungi from DT Bryophytes in tropical region.

In Canadian boreal forests, bryophytes represent an essential component of biodiversity and play a significant role in ecosystem functioning. Despite their ecological importance and sensitivity to disturbances, bryophytes are overlooked in conservation strategies due to knowledge gaps on their distribution, which is known as the Wallacean shortfall. Rare species deserve priority attention in conservation as they are at a high risk of extinction. This study aims to elaborate predictive models of rare bryophyte species in Canadian boreal forests using remote sensing-derived predictors in an Ensemble of Small Models (ESMs) framework. We hypothesize that high ESMs-based prediction accuracy can be achieved for rare bryophyte species despite their low number of occurrences. We also assess if there is a spatial correspondence between rare and overall bryophyte richness patterns. The study area is located in western Quebec and covers 72,292 km2. We selected 52 bryophyte species with <30 occurrences from a presence-only database (214 species, 389 plots in total). ESMs were built from Random Forest and Maxent techniques using remote sensing-derived predictors related to topography and vegetation. Lee’s L statistic was used to assess and map the spatial relationship between rare and overall bryophyte richness patterns. ESMs yielded poor to excellent prediction accuracy (AUC > 0.5) for 73% of the modeled species, with AUC values > 0.8 for 19 species, which confirmed our hypothesis. In fact, ESMs provided better predictions for the rarest bryophytes. Likewise, our study revealed a spatial concordance between rare and overall bryophyte richness patterns in different regions of the study area, which have important implications for conservation planning. This study demonstrates the potential of remote sensing for assessing and making predictions on inconspicuous and rare species across the landscape and lays the basis for the eventual inclusion of bryophytes into sustainable development planning.

Aquatic and rheophilous bryophytes can indicate water pollution as they bioaccumulate toxic water elements. We evaluated (1) bioaccumulation of eight heavy metals and arsenic by Marchantia polymorpha L., and (2) changes in bryophyte community structure, as responses to urban pollution in southern Ecuador. To this end, we registered presence/absence and coverage of submerged bryophytes in 120 quadrats across three zones of the Zamora river inside Loja city, and a control zone in a nearby forest. We found that the concentrations of five (Al, Cd, Cu, Fe, and Zn) of the eight chemical elements and arsenic were highest in urban M. polymorpha. Moreover, bryophyte species richness decreased in urban zones. Bryophyte community structure also differed between control and city zones, but no differences were found among city zones. The control zone was composed by a more distinct set of bryophyte species, e.g., an indicator species analysis showed that 16 species had high and significant indicator values for control zone, but only 11 species were indicators of at least one of the three urban zones. We concluded that bryophytes, in general, and M. polymorpha, in particular, can be suitable biomonitors of water quality in tropical urban rivers.

Caves represent sites of great geological and biological interest. For most taxonomic groups, caves represent one of the most challenging ecosystems due to their extreme conditions. However, these places are rich in biodiversity, and some groups, such as bryophytes, can take advantage of these conditions. Bryophytes from twelve caves on Terceira Island (Azores archipelago) were sampled and compared in terms of species richness, abundance, and composition. The results revealed a high species richness of bryophytes, with one-fifth of the species being threatened and one-third endemic. Moreover, the dominance of bryophyte species, as determined by different functional groups, varies depending on the sampled cave and, consequently, the environmental variables. This is evident from the high β-diversity values obtained, demonstrating significant dissimilarities in species composition among the surveyed caves. Both macro- and microclimatic variables significantly influenced the richness and abundance of bryophyte species in different ways, depending on the functional group studied. Highlighting bryophyte diversity in cave environments, this study points to the need for effective management strategies to preserve and protect these unique and ecologically significant communities. These places can serve as refuges for some species, even for bryophytes, a taxonomic group with a long-distance dispersal strategy.

Bryophytes were traditionally ignored in most studies of forest ecosystem processes, or they were included with litter or soil. In the last few decades we have begun to understand their many roles that permit them to be ecosystem engineers. This review serves to pull together many scattered sources into a single source on the many contributions bryophytes can perform as ecosystem engineers and to support what several authors have already stressed: that bryophytes should not be treated as a single functional group. It puts bryophytes in perspective in terms of richness and biomass, then explores their roles as ecosystem engineers; that is, their roles in altering diversity, nutrient cycling, carbon sequestering, water retention, erosion depression, temperature modification, fire protection, fire and logging recovery, interactions with mycorrhizal fungi, effects on seed germination, and seedling survival. Interactions with other species are mentioned, but those regarding animals are largely omitted in favor of more detailed description of their relationships with trees throughout the world. Bryophytes provide both positive and negative interactions with forest trees, depending on the tree species, the ecosystem, and the bryophyte species. It is clear that different bryophytes have many different functional roles in sustaining the forest and making it suitable for germination, seedling success, and maintaining the mature forest. This review indicates those important roles and how they apply differently according to both tree and bryophyte species, and that different management practices are needed, depending on both bryophyte species and tree species, to sustain different forest types.

Abstract Aim Overstorey tree species influence both soil properties and microclimate conditions in the forest floor, which in turn can induce changes in ground bryophyte communities. The aim of the study was to investigate the effect of tree species identity and the most important habitat factors influencing understorey bryophytes. Methods We assessed the effect of 14 tree species and related habitat parameters, including soil parameters, vascular plant presence and light intensity on bryophytes in monospecific plots covered by nearly fifty-year-old trees in the Siemianice Experimental Forest (Poland). Results The canopy tree species determined bryophyte species richness and cover. The strongest differences were observed between plots with deciduous and coniferous trees. Soils with a more acidic pH and lower content of macronutrients supported larger bryophyte coverage. We also found a positive correlations between vascular plants and availability of light as well as bryophyte species richness. Conclusion Tree species identity and differences in habitat conditions in the forest floor lead to changes of ground bryophyte richness, cover and species composition. Consequently, the changes in the dominant tree species in the stand may result in significant repercussions on ground bryophyte communities. We indicated that the introduction of alien tree species, i.e. Quercus rubra, has an adverse effect on bryophyte communities and suggested that the selection of tree species that contribute to the community consistent with the potential natural vegetation is highly beneficial for maintaining ground bryophyte biodiversity.

Bryophytes occurring in riparian systems where they are seasonally submerged or inundated are poorly documented in many parts of the world. The actual number of rheophytic bryophytes remains speculative but we believe the number could easily exceed 500 taxa. Rheophytic bryophytes generally display highly disjunct populations and adjacent rivers and streams can have considerably different species composition. Water management in the form of flood control, dams, and hydroelectric development can adversely impact many rheophytic bryophyte species and communities due to changes in river ecology, timing of water flow, and water temperature. Specimens of rheophytic bryophytes are underrepresented in herbaria and labels rarely indicate the actual micro-habitat and ecological attributes for bryophytes collected within riparian systems. Many rheophytes are morphological anomalies compared to their terrestrial relatives and the evolution of the rheophytic condition has occurred repeatedly in many bryophyte lineages.

Der volle Inhalt der QuelleAnnotation:
As forest management intensifies, the conservation of forest biodiversity is a growing concern. Bryophytes are known to represent a considerable portion of plant diversity within northern forests. This is because bryophyte diversity is closely associated with microhabitat diversity. In this study, the influence of microhabitats on bryophyte diversity was investigated by comparing eight different boreal mixedwood microhabitats. The results indicate that bryophyte diversity (species richness, abundance, and evenness) is quite variable among microhabitats. The accumulation of species richness with microhabitat quantity within a forest stand also varies among microhabitats. β-diversity analyses indicate that the variety of microhabitats has considerable influence on community structure. Frequency analysis identified bryophytes that are restricted to or prefer particular microhabitats. Although all microhabitats are important to bryophyte diversity, decayed logs and rocks supported the greatest number of microhabitat-specific species, and rock microhabitats supported the largest total number of species. Recommendations for forest management, one of which emphasizes the need to recognize and manage the natural variety of microhabitats, such as downed woody material, found within the forests to conserve or restore bryophyte diversity are provided.

On the territory of the Ivano-Frankivsk region were found 66 species of regionally rare bryophytes. Among them, mosses predominat, but the proportion of liverworts is significant. Based on the analysis of the taxonomic structure, it was established that the liverworts (Marchantiophyta) belong to 2 classes, 4 orders, 13 families, 16 genera, 19 species; mosses (Bryophyta) – to 3 classes, 12 orders, 20 families, 38 genera, 47 species. According to the number of species, bryophyte families are located as follows: Pottiaceae – 11 species (16,8 %); Brachytheciaceae – 5 (7,6 %); Cephaloziaceae and Splachnaceae – 3 (4,6 %), the rest of the families are oligo- and monospecies. Among rare species, the boreal geographical element predominates (27 species, 41,0 %), the following arid (11 species, 16,7 %), and nemoral (10 species, 15,1 %). The analysis of ecological groups of mosses and liverworts by type, chemistry, humidity, trophic and illuminance of the substrate is carried out. It was found that most rare species belong to the epigeous heliophytes. The chemistry of the substrate is dominated by acidoneutrophils, which grow on substrates with pH values from 3 to 7. The trophic dominance of species that occur on relatively nutrient-rich substrates; the humidity of the habitats is dominated by mesophytes, a significant hygrophytic group of species. Among the rare bryophytes, species with life forms of low turf, which occur mainly on soil and rocks, predominate. Most rare species with life forms of mats, tall turfs and wefts are confined to wetlands (swamps and shores of reservoirs), a significant part mat and short turfs – to rock outcrops. Sexual types of bryophytes and the presence of specialized organs of asexual reproduction have been determined. Rare species, confined to wet and humid ecotopes, are particularly sensitive to any changes in hydrothermal conditions.

The bryophyte flora of Vienna is documented only in parts. Old finds often appeared in publications about Lower Austria; only one study addressed the bryophytes of the inner city. Here, we present a bryophyte flora of Vienna, including historical reports and the results of recent investigations. From 1998 to 2023, we recorded 329 bryophyte taxa in Viennese urban territory. Fifty-six of these were liverworts, and 273 were mosses. Sixty-seven taxa are new for Vienna. Forty-nine taxa, given in historical studies, could no longer be found. If we also count these, 378 taxa occurred in Vienna to date. Of the current occurring bryophytes, 67 species have an endangerment classification. Rich in bryophytes were the dry grasslands of the Lobau, the oxbow lakes of the Lobau and the Prater, and large parts of the Wienerwald. But flat roofs and inner-city areas also showed more than 100 species. Compared to other European cities, Vienna is decidedly species-rich and highly responsible for some species in Austria. Reasons for this are the extensive green spaces and the pronounced climatic gradient from the sub-oceanic west to the sub-continental east of Vienna. Awareness raising for bryophytes we recommend in addition to the existing biotope protection.

Volatile emissions from 22 bryophyte species from Peninsular Malaysia were collected using a dynamic headspace technique and analyzed by gas chromatography–mass spectrometry (GC-MS). Thirty organic compounds (VOCs) from eight different groups were detected in bryophytes from the montane forest in Cameron Highlands and the lowland dipterocarp forest in Lata Belatan. The headspace of bryophytes in Cameron Highlands was dominated by tetradecane, 2-ethyl-1-hexanol, decanal, pentanoic acid, 2,2,4-trimethyl-3-carboxyisopropyl, isobutyl ester, D-limonene and naphthalene. On the contrary, in the bryophyte headspace of Lata Belatan, naphthalene and tetradecane were dominant compounds. The elevational pattern detected in VOC composition of bryophytes appears to be an evolutionary feature at the family level that needs verification at other sites. The results also confirmed that the VOC composition of bryophytes is species-specific. The roles of VOCs in bryophytes are presented, including plant–plant communication and plant–insect interaction and as an additional taxonomic character in chemotaxonomy.

The species number of bryophytes is the second highest among land plants. Alpine grasslands on the Qinghai–Tibet Plateau (QTP) are the largest among global alpine biomes. However, bryophyte flora in alpine grasslands on the QTP remains poorly explored relative to its large geographic extent. A total of 347 plots were surveyed across the QTP, and 149 bryophyte taxa in 24 families and 49 genera were recorded in alpine grasslands. The largest family was Pottiaceae, followed by Bryaceae and Brachytheciaceae. The most species-rich genus was Bryum, followed by Didymodon and Brachythecium. The dominant species were Didymodon tectorus, Didymodon fallax, Bryum caespiticium, Didymodon constrictus, and Didymodon ditrichoides. The Jaccard similarity indexes of bryophyte compositions between alpine meadow and alpine steppe at the family, genus, and species levels were 0.375, 0.367, and 0.282, respectively. Turf was the most common life-form (75.2%), followed by weft (16.1%) and cushion (5.4%). Endemic species to China accounted for 8.05% of the total taxa. Bryophyte diversity in alpine grasslands on the QTP is exceptional and irreplaceable. The changes in species composition and life-forms between different grassland types reflect the adaptations of bryophytes to harsh environments.

It has been widely documented that the complex structure of forest ecosystems supports considerable bryophyte species and functional diversity. In this study, we assessed the diversity, distribution and ecological and phytogeographical features of bryophytes across a gradient of temperate forest types on Mt. Papuk. This is the largest and highest mountain in the lowland, Pannonian part of Croatia, with high geological diversity and various temperate forests covering 95% of the mountain. According to the predominant tree species (oak vs. beech), geological bedrock (calcareous vs. siliceous) and soil reaction (alkaline vs. acidic), 21 study plots were classified into four distinct forest types. In all, 184 bryophyte species (35 liverworts and 149 mosses) were recorded. Although the forest types investigated did not differ significantly with respect to species richness, each was characterized by a considerable number of diagnostic bryophyte species. According to our results, one of the main ecological factors determining the variability of the forest bryophyte composition was geological bedrock and the associated soil reaction. Basiphilous forests developed on carbonate bedrock harbored more thermophilous and nitrophilous bryophytes and were characterized by southern-temperate and Mediterranean–Atlantic biogeographic elements. In contrast, acidophilous forests growing on silicate bedrock were characterized by wide-boreal and boreo-arctic–montane elements, i.e., bryophytes indicating cooler habitats and nitrogen-deficient soils. Based on the results, we hypothesized that the main latitudinal biogeographic distinction between southern and northern biogeographic elements is driven more by geological substrate than by the main tree species in forest communities. The present study confirmed previous findings that bryophytes are good and specific habitat indicators and show associations with different forest types, which can help to understand the complexity, ecological microconditions and biogeographic characteristics of forest communities.

There is currently limited information on plant biodiversity from Ghana. Most of the information openly available has been published by the Ghana Herbarium at the Department of Plant and Environmental Biology, University of Ghana. The Ghana Herbarium has over 100,000 specimens from Ghana and other West African countries. Of these approximately 85% of the specimen labels have been digitized. The database contains information including species names, taxonomic family, barcode number, name of collector(s), locality data, date of collection, description of species and uses of the plants. Data were captured using Botanical Research and Herbarium Management Software (BRAHMS) software and is openly available on Global Biodiversity Information Facility (GBIF) (http://www.gbif.org/country/GH/publishing). Less than 1% of the herbarium collection contains bryophyte information of Ghana. Even though bryophytes are an often overlooked flora, Ghana has a high diversity of bryophytes. Indeed Ghana has an enormous biomass of bryophytes, particularly in the humid forest areas, that is bound to contribute significantly to the water-retentive capacity of the Ghanaian forest, absorbing water quickly and releasing it slowly. It is clear that the bryophytes are an important part of the ecosystem generally, helping to stabilize the hillsides and acting as a source of water. As very little is known about Ghana's bryophyte flora, a short expedition was undertaken in the Atewa Forest in 2014. A total of 164 species were added to the herbarium collection, including about 58 new to Ghana and at least one new species (Cololejeunea sp. yet to be described). The Ghana Herbarium recognises the growing need for digitization across its collections. Data from bryophytes specimens in the Ghana Herbarium and other Ghanaian herbaria as well as other data types on Ghanaian bryophytes will need to be captured using appropriate workflows, technologies and comply with Darwin Core standards. There is also paucity of observational and bryophyte abundance data. This presentation will review the current status of biodiversity information on bryophytes from Ghana and biodiversity informatics activities at Ghana Herbarium. It will also explore ways forward for digitization which incudes capturing the information on the already existing bryophyte specimens in the Ghana Herbarium and the newly added collections using BRAHMS software.

To assess the spatial distribution of bryophyte species in Eastern Europe, more than 53,000 localities of 1296 species were analyzed in 397 squares of 100×100 km. In terms of frequency of occurrence, rare species (from 6 to 25 squares) and very rare (from 1 to 5 squares) prevail in Eastern Europe. It was shown that more than 60 % of the taxonomic diversity of bryophytes is in a threatened or close to threatened state in the region. Based on biogeographic zoning, 6 regions (alpine, arctic, boreal, nemoral, arid, subtropical) and 12 subregions were identified. The characteristics of the taxonomic diversity of bryophyte regions and subregions are given, specific species are given and the centers of concentration of bryophyte species diversity in Eastern Europe are identified. There are 162 species in only one subregion, and 68 bryophyte taxa are found in all regions and subregions. The maximum species diversity is observed in the Alpine region (1066 species), which is explained by the general nature of the biological characteristics of bryophytes, the variety of ecological conditions in this region and the presence in Eastern Europe of 4 geographically different mountain subregions: the west of the Kola Peninsula, the Urals, the Carpathians and the foothills of the Caucasus.

Volcanic lava cave habitats are extreme environments. We carried out field investigations for five years and reported the results of bryophyte diversity in eight volcanic lava caves of Jingpo Lake World Geopark, where the largest underground lava caves in China are preserved. The results are as follows: (1) A total of 230 quadrats were set up, and 2041 bryophyte specimens were collected. The specimens belong to 272 species of 107 genera in 47 families, including 26 liverworts (13 genera, 11 families) and 246 mosses (94 genera, 36 families). (2) The α diversity of bryophytes in Underground Lava Fall Cave was the highest, while that in Foggy Cave was the lowest. (3) The dominant families included Mniaceae, etc, accounting for 55.9% of the total species. The dominant genera included Plagiomnium, etc, accounting for 24.3% of the total species. The dominant species included Sanionia uncinata (Hedw.) Loeske etc. (4) There are no shared species among all eight lava caves, and each cave has a unique species composition. (5) Compared with that in other habitats in our previous studies, the similarity of bryophyte species between lava caves and underground forests of craters was high (113 species, 40.07%), while it was low between lava caves and lava platforms (9 species, 4.65%). Our study revealed that the lava caves have a high potential for bryophyte diversity, and such ancient ecological disaster sites are now rare refuges for bryophytes. Mosses are more adapted to cave habitats than liverworts. Bryophytes in this special eco-environment need to be considered and protected in order to preserve high-quality gene resources for humans, which is of great significance for the maintenance and development of biodiversity.

Fruska Gora is a mountain located in the southern part of Pannonian plane and it is poorly bryologicaly investigated as well as most parts of Serbia. First data on bryophytes, for this region, were published in 1949 by Teodor Soska in his paper Pregled mahovina i lisajeva u okolini Beograda (Review of mosses and lichens in the vicinity of Belgrade). Soska listed 34 species of mosses and 8 liverworts species for this region. Later, in 1955, Zlatko Pavletic in his capital work Prodromus flore briofita Jugoslavije (Prodromus of Yugoslavian bryophyte flora), stated 26 moss species and 3 liverwort species, without indicating specific localities, but all of them were Soska?s original results. In 1966, the second botanist with original findings of bryophytes on Fruska Gora was Popovic, who recorded 2 liverwort and 19 moss species, for this mountain, also without specific localities. By far, the most comprehensive data were given by Cvetic and Sabovljevic in 2004. Their study A contribution to the bryophyte flora of Fruska Gora (Vojvodina, Serbia) counted total number of 118 mosses and 14 liverworts, on 16 localities within National park Fruska Gora. The latest study on bryophytes of Fruska Gora was in 2013, and it is the first and so far, the last study of bryophyte assemblages on grasslands. Authors of this paper recorded 18 species of mosses from 29 releve?. Complete bryophyte flora of Fruska Gora is still unknown. Considering the fact that this is the region with high biodiversity, dense hydrological network and a rather complex geology, Fruska Gora certainly deserves further bryological researches.

Abstract In dry habitats of European lowlands terricolous lichens and bryophytes are almost neglected in conservation practises, even if they may strongly contribute to biodiversity. This study aims at (a) testing the role of heathlands, acidic and calcareous dry grasslands for lichen and bryophyte diversity and conservation in lowland areas of northern Italy characterized by high human impact and habitat fragmentation; (b) detecting the effect of environmental drivers and vegetation dynamics on species richness and composition. Lichens, bryophytes, vascular plants, and environmental variables were recorded in 287 circular plots for 75 sites. Our results indicate that heathlands, acidic and calcareous dry grasslands host peculiar terricolous lichen and bryophyte communities that include several species of conservation concern. Thus, each habitat provides a complementary contribution to lichen and bryophyte diversity in continental lowland landscapes. Furthermore, in each habitat different factors drive species richness and composition with contrasting patterns between lichens and bryophytes. In terms of conservation, our results indicate that management of lowland dry habitats should act at both local and landscape scales. At local scale, vegetation dynamics should be controlled in order to avoid biodiversity loss due to vegetation dynamics and wood encroachment. At the landscape scale, patches of all the three habitats should be maintained to maximize regional diversity.

Retention of trees from the previous generation is one of the most widespread conservation practices in forests used for timber production. Despite the comparatively long history of this approach in Europe, there is a lack of long-term studies on the effectiveness of retention trees in preserving epiphyte communities. We compared the diversity of bryophyte and lichen species on retention trees in 20 young forest stands in Latvia in two assessments, 11 years and 18 years after clearfelling. Linear mixed-effects models showed that richness of both lichens and bryophytes remained stable during the assessment years, while bryophyte cover and diversity on retention trees increased over time. The main indicator of higher species richness, cover and diversity on retention trees in managed forests in hemi-boreal vegetation zone was the tree species, with deciduous trees playing the key role. They also provided essential habitat for rare species. Regarding bryophytes, ash, elm, and aspen can be suggested as more efficient retention trees, thus aiding the continuity of bryophyte succession in young forest stands. For lichens, lime could also be prioritised.

Study on the impact of differences in altitude and land use changes was conducted in natural forest, coffee and tea plantations in along altitudinal gradient of Ungaran mountain from 750 to 2040 m a.s.l. The objective of this study were to compare composition of epiphytic bryophytes species in third sites. Epiphytic bryophytes sampling were done in plots 20 x 30 cm were applied on height of tree betwen 0-2 m. A total of 103 species of epiphytics bryophytes were identified, involve 58 species of mosses (Bryophyta Division) and 45 species of liverworts (Marchantiophyta Division). The composition of bryophytes in natural forest is more diverse than in coffee and tea plantations. Lejeunaceae have the highest number of species. There are seven life forms of epiphytic bryophytes in the present study i.e. Turf, Cushion, Mats, Wefts, Dendroid, Pendant and Fans. The most common is Mats and Turf form, while Pendant and Dendroid form only found in natural forest. Key words: Bryophytes, epiphytes, altitude, land use changes, life form

This study is a survey of the bryophyte species that occur on the trunks of Cyathea delgadii Sternb. (Cyatheaceae), a native tree fern, encountered in a fragment of Atlantic forest located in the area of the „Parque Estadual das Fontes do Ipiranga (PEFI)“, São Paulo State, Brazil. Specimens of bryophytes were collected from March 2001 to October 2003. We found 35 bryophyte species (12 spp. of mosses and 23 of liverworts). Ceratolejeuenea dentacornuta Steph. is presented as a new record for Brazil. A brief discussion about previous records of bryophyte species growing on trunks of tree ferns in Brazil is also presented.

The Guianas (French Guiana, Suriname, Guyana) are probably one of the last areas of the world covered largely by virgin lowland rain forest. Species diversity of epiphytic bryophytes was investigated in dry evergreen forest and mixed forest using mountaineering techniques to ascend into the canopy. The results indicate that the lowland rain forest is richer in species than previously believed due to neglect of the canopy flora, which may hold more than 50% of the local species. The mixed forest holds the richest flora and on one single forest tree up to 67 bryophyte species were found (50 on average); 28 trees yielded 154 species. A species/area curve indicates that epiphytic bryophyte species are usually commonly distributed in the forest and a few trees may yield much of the local flora. A recent checklist of the Guianas includes over 600 species of bryophytes: 375 Hepaticae and 234 Musci. As the region lacks in altitude (except on Mt. Roraima) the general character of the bryophyte flora of the Guianas is typically lowland neotropical. Over 80% of the species are rather widespread in tropical America (Amazonian species included), and the remaining are Guayana Highlands, northern Amazonian or Caribbean elements. Endemism is very low: 2.5 %.
