Full textAbstract:
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.

Full textAbstract:
Bryophytes are considered the oldest living plants of terrestrial habitats and the closest modern relatives of the ancestors of the earliest terrestrial plants. Bryophytes are found on all continents and occupy xeric to aquatic niches, with the greatest diversity and biomass in cool temperate regions. Despite the lesser popularity of these organisms, bryophytes have ethnopharmacological importance in different cultures of the world, especially in Chinese, Indian, and Native American medicine. Different bryophyte extracts and isolated compounds have shown anti-microbial, antiviral, and cytotoxic effects. The present overview aims to highlight the use of bryophytes for the treatment of common ailments in folk medicine around the world and to collect, analyze, and summarize the available literature on the pharmacological activity of the most used mosses and liverworts. Based on the literature review, 109 wild taxa of Bryophyta being used for ethnomedical purposes have been documented. Overall, 170 uses were recorded for the 109 taxa considered. Herbal remedies for skin and hair care are by far the most commonly reported (25.0%); antipyretic uses of bryophytes account for 12.2%, while taxa used as medicinal treatments for respiratory and gastro-intestinal systems amount to 12.1% and 9.9%, respectively.

Full textAbstract:
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.

Full textAbstract:
AbstractForestry-related land use can cause increasing instream sedimentation, burying and eradicating stream bryophytes, with severe ecological consequences. However, there is limited understanding of the relative roles and overall importance of the two frequently co-occurring stressors, increased fine sediments and loss of bryophytes, to stream biodiversity and ecosystem functions. By using random forest modeling and partial dependence functions, we studied the relative importance of stream bryophytes and fine sediments to multiple biological endpoints (leaf-decaying fungi, diatom, bryophyte, and benthic macroinvertebrate communities; leaf decomposition) using field survey data from headwater streams. Stream bryophyte abundance and richness were negatively related to fine sediment cover, highlighting the detrimental effect of sedimentation on bryophytes. However, bryophyte abundance was consistently more important a determinant of variation in community composition than was fine sediment cover. Leaf decomposition was influenced by shredder abundance, water temperature and, to a lesser degree, stream size. Our results suggest that the loss of stream bryophytes due to increasing sedimentation, rather than fine sediments per se, seems to be the key factor affecting multiple biological responses. Enhancing the re-establishment of bryophyte stands could partly compensate for the negative impacts of sedimentation on bryophytes and, consequently, on several other components of boreal stream ecosystems.

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.

Full textAbstract:
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.

Full textAbstract:
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.

Full textAbstract:
The pre-Cenozoic bryophyte fossil record is significantly sparser than that of vascular plants or Cenozoic bryophytes. This situation has been traditionally attributed to a hypothesized low preservation potential of the plants. However, instances of excellent pre-Cenozoic bryophyte preservation and the results of experiments simulating fossilization contradict this traditional interpretation, suggesting that bryophytes have good preservation potential. Studies of an anatomically preserved Early Cretaceous (Valanginian) plant fossil assemblage on Vancouver Island (British Columbia), at Apple Bay, focusing on the cryptogamic flora, have revealed an abundant bryophyte component. The Apple Bay flora hosts one of the most diverse bryophyte assemblages worldwide, with at least nine distinct moss types (polytrichaceous, leucobryaceous, tricostate), one complex thalloid liverwort, and two other thalloid plants (representing bryophyte or pteridophyte gametophytes), which contribute a significant fraction of biodiversity to the pre-Cenozoic fossil record of bryophytes. These results (i) corroborate previous observations and studies, indicating that the preservation potential of bryophytes is much better than traditionally thought; (ii) indicate that the bryophyte fossil record is incompletely explored and many more bryophyte fossils are hidden in the rock record, awaiting discovery; and (iii) suggest that the paucity of the pre-Cenozoic bryophyte fossil record is primarily a reflection of inadequate paleobryological capacity.

Full textAbstract:
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.

Full textAbstract:
The biogeography of bryophytes present in Serbia is analysed for the first time in this paper. Bryophyte spectra in different regions and units within the country are compared with each other, as well as with the Southeast European spectrum. The obtained results show similarities and differences in comparison with Southeast European bryophyte spectra, reveal certain biogeographical peculiarities of Serbia?s bryophytes and indicate regions of the country with an under-recorded bryoflora. The biogeographical characteristics of bryophytes also suggest a strong overlap with local climate types. These results should be taken into consideration when preparing a national strategy for conservation and management of bryophyte diversity.

Full textAbstract:
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.

Full textAbstract:
The species diversity and substratum preferencies of Bryophytes in the territory of the local park-monument park “Snopkivsky” in the urban ecosystem of Lviv are given in the article. The bryoflora of the Snopkivsky Park includes 61 species of bryophytes from the divisions Marchantiophyta and Bryophyta. The high position of the families Brachytheciaceae, Orthotricaceae, Pottiaceae, Bryaceae in the floristic spectrum reflects the specificity of the park’s local conditions. The percentage of these families in the floristic spectrum is 45.9 % of the total species richness. This distribution is characteristic of aridic natural zones, which indicates the dry condition of the urban microclimate. At the same time, a good representation of the boreal and nemoral forest families such as Mniaceae, Amblystegiaceae, Hypnaceae (21.3 % of the total species richness) reflects the natural features of the territory (the zone of broad-leaved forests), which spontaneously reproduced on part of the Park territory or were created artificially in ornamental gardening. In this part of the Park with spontaneous silvatisation the largest number of bryophyte species is concentrated and the moss cover is the most abundant. Poor representation of Marchantiophytes indicates a significant degree of anthropization of the studied urban ecosystem. There is an increase in the number of anthropogenic ecotopes in the Park, which is reflected in a significant upgrowth in the fraction of epilithic bryophyte species. Ravines and abandoned quarries have the greatest conservation value for mosses on the Park territory. Some anthropophobic species as components of epigeic, epiphytic and epixylic substrates groups, which are not characteristic of intensively urbanized areas, are occur here. No rare bryophyte species were found within the park. However, floating liverwort Riccia fluitans, which is not typical for urban areas in general, was found in the Zelene Oko lake. Calcareous tufa deposited in the bed of hard-water streams at the headwaters of the Snopkivsky stream is a specific habitat for bryophytes. Indicators for hard-water springs with tufa formation of European lowland arias bryophytes species (Apopellia endiviifolia, Cratoneuron filicinum and Platyhypnidium riparoides) were found here. Amphibious (primarily calciphilic tufa-forming) and free-floating bryophyte species are equally not typical for urbanized ecosystems and occur here only sporadically: this fact underlines the conservation value of the researched park for the preservation of bryophytes microhabitats within the city boundaries. The conservation of silvatic areas, both spontaneous and artificial, is an important condition for the effective functioning of the park as a semi-natural ecosystem. The diversity of bryophytes, their species composition and cover abundance are indicative of the integrity of urban ecosystems on the territory of the park “Snopkivsky”.

Full textAbstract:
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.

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.

Full textAbstract:
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.

Full textAbstract:
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.

Full textAbstract:
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.

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 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.

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.

Full textAbstract:
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.

Full textAbstract:
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.

Full textAbstract:
The pH of tree bark is affected by many factors, amongst them epiphytic bryophytes changing in their active state environment. Thus, we hypothesized that bryophytes can change bark acidity, dependently of the inclination of the branches, as inclination affect the water regime and particle deposition. We measured the pH under bryophyte cushions and compared it to nearby naked bark. Additionally, we compared results with experimental bark covering with neutral cover. We found that the pH of naked bark declines with decreasing inclination of trunks. Although bryophyte cover did not generally change the pH of the bark, there was a significant interaction with inclination: with higher inclination, bryophytes decrease the pH reaction of bark, while with lower inclination they increase it. One possible explanation may lie in changes to alkaline particle deposition, or conversely in the acidification of the bark by leaching. In addition, an experiment with a neutral cover showed that naked bark covering would substantially increase pH. As, on average, bryophytes do not change the pH of bark, there can be mutual interference between the alkalizing effect of the bark cover itself and the acidifying biological effect of bryophytes.

Full textAbstract:
Despite being recognized as a widespread and evolutionary important phenomenon among vascular plants, interspecific hybridization among bryophytes has been strongly underestimated. In the present review, we summarize knowledge about bryophyte hybrids that are found in nature. Mechanisms of reproductive isolation in bryophytes are compared with those in vascular plants. The morphological and genetic features of sporophytic hybrids and their gametophytic progeny are discussed, as well as some inferences about hybrid fitness. The data available indicate that spontaneous hybridization among bryophytes is not uncommon and has an important, though still not completely understood, evolutionary significance. The existence of many allopolyploid taxa supports this conclusion. Finally we suggest some methods for further investigation of hybridization among bryophytes in nature.Key words: hybridization, bryophytes, isolating mechanisms, evolution, hybrid fitness, hybrid features.

Full textAbstract:
Forests play crucial roles in regulating the amount and timing of streamflow through the water storage function. Bryophytes contribute to this increase in water storage owing to their high water-holding capacity; however, they might be severely damaged by climate warming. This study examined the water storage capacity (WSC) of bryophytes in forests in the mountainous areas of Japan. Sampling plots (100 m2) were established along two mountainous trails at 200-m altitude intervals. Bryophytes were sampled in these plots using 100-cm2 quadrats, and their WSC was evaluated according to the maximum amount of water retained in them (WSC-quadrat). The total amount of water in bryophytes within each plot (WSC-plot) was then calculated. The WSC-quadrat was affected by the forms of bryophyte communities (life forms) and their interactions, further influencing soil moisture. The WSC-quadrat did not show any significant trend with altitude, whereas, the highest WSC-plot values were obtained in subalpine forests. These changes to WSC-plot were explained by large differences in bryophyte cover with altitude. As the WSC controlled by the life forms might be vulnerable to climate warming, it can provide an early indicator of how bryophyte WCS and associated biological activities are influenced.

Full textAbstract:
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.

Full textAbstract:
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.

The paper attempts to find the characters which can distinguish the spores of Hepaticae and Anthocerotales from iso- or micro-spores of pteridophytes and pollen grains of gymnosperms and angiosperms for the identification of possible fossil Sporae dispersae of bryophytes reported from different geological horizons. The problem was approached by looking for characters in fossil spores which are (i) exclusively bryophytic, (ii) prevailingly bryophytic, and (iii) closely matching characters of in situ spores of fossil bryophytes in a first-hand comparison. Our account also takes into consideration the Sporae dispersae which were described or suspected by previous workers as those of bryophytes but which could equally well belong to pteridophytes.

Full textAbstract:
Epiphytic bryophytes are known to perform essential ecosystem functions, but their sensitivity to environmental quality and change makes their survival and development vulnerable to global changes, especially habitat loss in urban environments. Fortunately, extensive urban tree planting programs worldwide have had a positive effect on the colonization and development of epiphytic bryophytes. However, how epiphytic bryophytes occur and grow on planted trees remain poorly known, especially in urban environments. In the present study, we surveyed the distribution of epiphytic bryophytes on tree trunks in a Schima superba Gardn. et Champ. urban plantation and then developed count data models, including tree characteristics, stand characteristics, human disturbance, terrain factors, and microclimate to predict the drivers on epiphytic bryophyte recruitment. Different counting models (Poisson, Negative binomial, Zero-inflated Poisson, Zero-inflated negative binomial, Hurdle-Poisson, Hurdle-negative binomial) were compared for a data analysis to account for the zero-inflated data structure. Our results show that (i) the shaded side and base of tree trunks were the preferred locations for bryophytes to colonize in urban plantations, (ii) both hurdle models performed well in modeling epiphytic bryophyte recruitment, and (iii) both hurdle models showed that the tree height, diameter at breast height (DBH), leaf area index (LAI), and altitude (ALT) promoted the occurrence of epiphytic bryophytes, but the height under branch and interference intensity of human activities opposed the occurrence of epiphytic bryophytes. Specifically, DBH and LAI had positive effects on the species richness recruitment count; similarly, DBH and ALT had positive effects on the abundance recruitment count, but slope had a negative effect. To promote the occurrence and growth of epiphytic bryophytes in urban tree planting programs, we suggest that managers regulate suitable habitats by cultivating and protecting large trees, promoting canopy closure, and controlling human disturbance.

AbstractBryophytes (including mosses, liverworts and hornworts) are a heterogeneous group of terrestrial plants, which comprise over 24,000 species worldwide. Given the various biological activities reported from bryophytes, they have a huge commercial potential. Due to their minute size and rather small biomass in various ecosystems, bryophytes are a seldom part of ethnomedicine and rarely subject to medicinal and chemical analyses. Still, hundreds of novel natural products have been isolated from bryophytes. Bryophytes have been shown to contain numerous potentially useful natural products, including polysaccharides, lipids, rare amino acids, terpenoids, phenylpropanoids, quinones and many other specialized metabolites. Additionally, different bryophyte extracts and isolated compounds have shown antimicrobial, antiviral, cytotoxic, nematocidal, insecticidal, effects on smooth and non-striated muscles, weight loss, plant growth regulators and allelopathic activities. Bryophytes also cause allergies and contact dermatitis. All these effects highlight bryophytes as potential source for herbal remedies and production of chemicals to be used in various products.

Full textAbstract:
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.

Abstract Bryophytes are the second largest taxonomic group in the plant kingdom. They contain a high number of biologically active compounds. Studies of their composition are important for understanding evolutionary processes in the plant kingdom. The aim of this study was to assess bryophyte secondary metabolite extraction options and to increase the yields of polyphenols and substances determining the free radical scavenging activity of bryophyte extracts. Similar studies have been conducted using higher plants as model organisms, but not using bryophytes. Comparison of five extraction methods (conventional, Soxhlet extraction, treatment with microwaves, ultrasound, and supercritical CO2 extraction) and several solvents with differing polarity showed microwave-assisted extraction as the most promising approach to obtain highest yields of extractives. The main factors that contributed to the efficiency of extraction were type of solvent, temperature, and the solvent to bryophyte mass ratio. The extracts obtained from bryophytes had remarkable antioxidant activity, the extent of which depended on the extraction conditions and bryophyte species. The extraction conditions can be optimised, and the total polyphenol content can be increased by up to 50% in comparison with the conventional approach.

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.

Full textAbstract:
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.

Bryophytes are a poorly studied group of land plants that have been used in traditional medicine as a multipurpose remedy for centuries. Due to their peculiar morphology and physiology, bryophytes synthesise a multitude of secondary metabolites with a wide range of nutraceutical and pharmaceutical activities. Research has highlighted that secondary metabolites in bryophytes can also act as antitumour agents. Several studies have shown that bryophyte extracts and pure metabolites are cytotoxic against many cancer cell lines. Interestingly, some of these molecules and their derivatives are capable of acting on a specific target in cancer cells. Some macrocyclic(bis)bibenzyls from bryophytes can inhibit P-glycoprotein, reverting multidrug resistant cancer cell phenotypes, induce depolymerization of tubulin, stimulate apoptotic pathways, and inhibit angiogenesis. This brief review aims to collect recent knowledge on secondary metabolites of bryophytes and their derivatives, which have demonstrated an interaction with different molecular processes in cancer cells.

Full textAbstract:
Bryophytes play an important role in biogeochemical cycles and functions in forest ecosystems. Global climate changes have led to the population decline of bryophytes; however, the effects of bryophyte loss on the soil organic carbon stock and microbial dynamic remain poorly understood. Here, bryophytes were artificially removed to simulate the loss of bryophytes in two forests in Southwest China, i.e., evergreen broad-leaved forest and temperate coniferous forest. Soil physicochemical properties, microorganisms, and soil organic carbon stocks were analyzed and factors regulating soil organic carbon stocks were explored. Results showed that bryophyte removal significantly decreased soil organic carbon in the coniferous forest but had a negligible effect on the evergreen broad-leaved forest. Bryophyte removal had an insignificant effect on soil properties and microbial PLFAs except that soil nitrogen significantly increased in the 0–10 cm layer in the evergreen broad-leaved forest, while soil temperature and bulk density increased in the coniferous forest in the 0–10 and 10–20 soil layers, respectively. Soil organic carbon stocks increased by 14.06% in the evergreen forest and decreased by 14.39% in the coniferous forest. In the evergreen forest, most soil properties and microorganisms contributed to the change of soil organic carbon stocks, however, only soil organic carbon and depth had significant effects in the coniferous forest. Our findings suggest that soil physiochemical properties and microorganisms regulated the different responses of soil organic carbon stocks after bryophyte removal in the two forests. More research is needed to better understand the effects of understory plants on soil organic carbon stocks in various forest ecosystems.

Epiphytic bryophytes can maintain water, recycle nutrients, and provide habitats for many other organisms in the forest ecosystem. Describing the spatial change of epiphytic bryophytes plays an important role in understanding the potential factors of diversity distribution. The study aimed to determine the influence of environmental factors on their diversity and assemblage in the alpine forest ecosystem of Sygera Mountain. We considered 72 trees, taking into account 1152 quadrats to research the study. Our results showed bryophyte richness first exhibited a hump-shaped pattern and then increased along elevation, reaching a peak at 3500 m. The richness of the eastern aspect was higher than that of the west. Diversity of Quercus semecarpifolia was the highest. There was significant variation among elevations of bryophytes assemblages, especially for the biotopes at 3900 m and 4100 m. The differences among bryophytes assemblages on aspects and tree species were less apparent. Diameter at breast height and elevation influenced assemblage composition. Elevation, tree species, and tree properties drive the diversity of epiphytic bryophytes, and tree species were significantly related to the variation in the diversity of bryophytes. These results are helpful for understanding the relationship between the spatial distribution pattern of bryophytes and the environment.

Full textAbstract:
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.

Bryophyte is a division of plants that lives on land, generally it is green and reproduces through spores, has ecological and economic functions, and plays an important role in forest ecosystems. It spreads out almost in all parts of the earth with different characters in each group. It is divided into 3 groups, namely liverwort, true moss, and hornwort, which are phylogeny and true liverwort is in the same lineage. The number of bryophytes species is around 18000 with the largest distribution area of bryophyte diversity in tropical and subtropical latitudes, such as the Malesia region which includes Malaysia, Indonesia, Timor Leste, Papua New Guinea, the Philippines, and Brunei. Various studies were carried out related to the diversity of bryophyte, especially in the Malesia region, and found various types including new species, new records, and new characters.

Full textAbstract:
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.

Full textAbstract:
The dynamics of epiphytic bryophyte communities following natural and human disturbance have rarely been quantified. We describe the response of bryophyte communities on bigleaf maple trees (Acer macrophyllum Pursh) in Olympia, Washington, following their experimental removal. Approximately 8% of the exposed area was recolonized by bryophytes 1 year after clearing, and 27% after 3 years. Lateral encroachment from bryophytes on the sides of the 20-cm-long plots accounted for 75% of this recolonization, with growth from residual plant parts or aerially dispersed diaspores accounting for the remaining 25%. Though it was not possible to distinguish between the latter two sources of cover, the number of clear de novo colonization events over the course of the year was low (0.18 dm-2). Disturbance appeared to reduce bryophyte diversity at this successional stage, as alpha and gamma diversity remained low after 1 year and had not recovered after 3 years. Reflecting the preponderance of lateral encroachment as the mechanism for recolonization, disturbance size may significantly affect the time needed to recolonize disturbed branch substrates. In addition to contributing to ecologists' understanding of processes of succession, these experiments may help to develop sustainable practices for moss-harvesting in the Pacific Northwest.Key words: succession, bryophytes, epiphytes, Acer macrophyllum, recolonization, canopy studies.

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.

Full textAbstract:
Historically, Bryophytes were accounted to be a monophyletic group and were placed in an inclusive Bryophyta. Some species are aquatic though some can adapt and live in arid regions. Bryophytes size ranges from microscopic to 12 inches in length, the average size is between 0.5 – 2 inches long and colors vary from green to black and sometimes colorless. Bryophytes plays a vital role in the biosphere even their size is insignificant. As a biotic factor in the environment, they provide food for numerous herbivorous birds and animals. They prevent soil erosion by carpeting the soil. Bryophytes cause the outer portion of rock to slowly crumble as they grow with lichens on rock surfaces. And because of it they contribute and help to soil formation. When mixed with the soil, bryophytes increase the water-holding capacity of the soil and the amount of organic matter in the soil. Some bryophytes like sphagnum or peat moss has some economicimportance. It is used as packing material for breakable or fragile objects such as figurines and dinnerware’s. It is also used as packing materials for transporting plants and plant parts, since sphagnum holds water and hence prevent plants from drying during transport. As a whole, bryophytes are of little economic importance to man.
