Tomescu, Alexandru M. F. "The Early Cretaceous Apple Bay flora of Vancouver Island: a hotspot of fossil bryophyte diversity." Botany 94, no. 9 (September 2016): 683–95. http://dx.doi.org/10.1139/cjb-2016-0054.
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.

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:
Bryophytes are commonly used in biomonitoring heavy metal pollution, whereas the bioindicative value of bryophyte communities is a less known issue. 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.

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:
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.

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.

Full textAbstract:
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:
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.

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:
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.

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:
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.

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:
Abstract. Bryophyte and lichen cover on the forest floor at high latitudes exerts an insulating effect on the ground. In this way, the cover decreases mean annual soil temperature and can protect permafrost soil. Climate change, however, may change bryophyte and lichen cover, with effects on the permafrost state and related carbon balance. It is, therefore, crucial to predict how the bryophyte and lichen cover will react to environmental change at the global scale. To date, current global land surface models contain only empirical representations of the bryophyte and lichen cover, which makes it impractical to predict the future state and function of bryophytes and lichens. For this reason, we integrate a process-based model of bryophyte and lichen growth into the global land surface model JSBACH (Jena Scheme for Biosphere–Atmosphere Coupling in Hamburg). The model simulates bryophyte and lichen cover on upland sites. Wetlands are not included. We take into account the dynamic nature of the thermal properties of the bryophyte and lichen cover and their relation to environmental factors. Subsequently, we compare simulations with and without bryophyte and lichen cover to quantify the insulating effect of the organisms on the soil. We find an average cooling effect of the bryophyte and lichen cover of 2.7 K on temperature in the topsoil for the region north of 50° N under the current climate. Locally, a cooling of up to 5.7 K may be reached. Moreover, we show that using a simple, empirical representation of the bryophyte and lichen cover without dynamic properties only results in an average cooling of around 0.5 K. This suggests that (a) bryophytes and lichens have a significant impact on soil temperature in high-latitude ecosystems and (b) a process-based description of their thermal properties is necessary for a realistic representation of the cooling effect. The advanced land surface scheme, including a dynamic bryophyte and lichen model, will be the basis for an improved future projection of land–atmosphere heat and carbon exchange.

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.

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 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:
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.

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 dominant components of boreal forest understories and play a large role in regulating soil microclimate and nutrient cycling. Therefore, shifts in bryophyte communities have the potential to affect boreal forests’ ecosystem processes. We investigated how bryophyte communities varied in 83 forest stands in interior Alaska that ranged in age (since fire) from 8 to 163 years and had canopies dominated by deciduous broadleaf (Populus tremuloides Michx. or Betula neoalaskana Sarg.) or coniferous trees (Picea mariana Mill B.S.P.). In each stand, we measured bryophyte community composition, along with environmental variables (e.g., organic layer depth, leaf litter cover, moisture). Bryophyte communities were initially similar in deciduous vs. coniferous forests but diverged in older stands in association with changes in organic layer depth and leaf litter cover. Our data suggest two tipping points in bryophyte succession: one at the disappearance of early colonizing taxa 20 years after fire and another at 40 years after fire, which corresponds to canopy closure and differential leaf litter inputs in mature deciduous and coniferous canopies. Our results enhance understanding of the processes that shape compositional patterns and ecosystem services of bryophytes in relation to stand age, canopy composition, and changing disturbances such as fire that may trigger changes in canopy composition.

Full textAbstract:
The species richness and species composition of bryophytes (mosses and liverworts) was recorded at 33 sites in Tasmanian old growth mixed eucalypt forest. A total of 202 bryophyte taxa were recorded, consisting of 115 liverworts and 87 mosses. This constitutes approximately one third of the total bryophyte flora for Tasmania. Mean liverwort species richness per site was higher than moss species richness. Latitude was found to be a positive predictor in all multiple regression models of bryophyte, moss and liverwort species richness. Mean annual temperature and rainfall of the driest month were positive predictors for bryophyte and liverwort species richness. Basal area of the treefern Dicksonia antarctica Labill. was a negative predictor of liverwort species richness. Latitude, variables relating to moisture, mean annual temperature, rainfall of the driest month and basal area of Dicksonia antarctica were the most significant components in predicting variation in bryophyte, moss and liverwort species composition. There were few relationships between the variables of canopy cover and soil nutrients and bryophyte species richness and composition. Substrate variables were found to be important components in predicting variation in moss and bryophyte species composition.

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:
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.

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 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.

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:
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.

Full textAbstract:
Animal dispersal influences the community structure and diversity of a wide variety of plant taxa, yet the potential effects of animal dispersal in bryophytes (hornworts, liverworts, and mosses) is poorly understood. In many communities, birds use bryophyte-abundant niche space for foraging and gathering nest material, suggesting that birds may play a role in bryophyte dispersal. As highly motile animals with long migratory routes, birds potentially provide a means for both local and long-distance bryophyte dispersal in a manner that differs greatly from passive, aerial spore dispersal. To examine this phenomenon, we collected and germinated bryophyte propagules from the legs, feet and tails of 224 birds from 34 species within a temperate forest community. In total we found 1512 spores, and were able to germinate 242 bryophyte propagules. In addition, we provide evidence that topical (externally-carried) spore load varies by bird species and behaviour. Tail feather spore abundance is highest in bark and foliage gleaning species and is positively correlated with tarsal length. Together, these data suggest that a variety of forest birds exhibit the potential to act as dispersal vectors for bryophyte propagules, including an abundance of spores, and that understanding the effects of animal behaviour on bryophyte dispersal will be key to further understanding this interaction.

Full textAbstract:
Drought exposure in the upper canopy of tropical montane rain forest (Guadeloupe) leads to the pulsed release of solutes from epiphytic bryophytes within the cloud forest canopy. This efflux, leached from newly rewetted mosses and hepatics, was greatest for ions normally held within intracellular pools. Estimates of solute efflux from stem segments of canopy bryophytes reached 80.1 kg ha−1 year−1 for K, 1.4 kg ha−1 year−1 for P, and 11.8 kg hal−1 year−1 for N during experimental rewetting episodes. Estimates of solute efflux from intact bryophyte mats during field rewetting episodes were smaller, only 28.7 kg ha−1 year−1 for K and 0.2 kg ha−1 year−1 for P. The difference between these measurements is thought to reflect internal recycling of released ions within the canopy bryophyte mats during rewetting episodes. Nonetheless, nutrient loss to throughflow solution represents a significant portion of the standing nutrient capital held within canopy bryophyte mats. By releasing previously sequestered nutrients, bryophyte communities not only provide access to resource pools that would otherwise be inaccessible, but may stimulate the further transformation of nutrients as leaf epiphyll and decomposer communities respond to enriched throughflow solution pulses. These data suggest that recycling of nutrients between members of the standing biomass in tropical montane rain forest is not a steady state process, as often envisaged, but rather may be highly episodic in nature. Key words: tropical montane rain forest, bryophytes, epiphytes, nutrient cycling, throughflow.

A comparative study of epiphytic bryophytes on tree trunks was undertaken in three principal vegetation types along an elevational gradient on the windward wet side of the largest island in Fiji, Viti Levu. This ecological study is the first of its kind for Fiji and the islands of the South Pacific and it serves as groundwork for any future ecological research in the region for bryophytes. This study set out to test if elevational range of study sites and height along host tree stem influenced bryophyte species diversity and distribution in Fiji. This was done by assessing bryophyte species presence/absence on the lower stems of the Calophyllum spp. trees and tree fern species at three elevations (~160 m, 590 m, and 1260 m). There were two main findings that emerged from this preliminary assessment. Firstly, there was a hump-shaped distribution of bryophyte diversity with a peak of species richness observed at mid-elevation or in the upland forest; with a dominance of liverworts at each of the three elevations. Secondly, the bryophyte communities showed good separation at both host tree level and at the site level, reflecting the ecological differences between the different host trees and between the three sites along the elevational gradient. The results from this survey alone suggest the need for priority to be given to upland forest protection and conservation. It also demonstrates the usefulness of bryophyte communities in discerning vegetation of different environmental and microclimatic conditions along an elevational gradient.

An assessment of diversity of bryophytes at Ghoom, Darjeeling Hills has been made. A total of 47 species belonging to 37 genera and 26 families have been identified during the study. Six habitats were selected to compare relative bryophyte distribution. Evaluation of the bryophyte distribution in different habitats has been done with an observation of different growth forms occurring in the area. It has been noticed that bryophyte diversity in terms of number of taxa was quite low here as compared to nearby Jalapahar and Senchal Wildlife Sanctuary of Darjeeling hills surveyed during study, owing to higher level of pollution and habitat loss due to constant anthropogenic movement.

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.

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:
Return of wood ash from power plants to plantations makes it possible to recycle nutrients, counteract acidification, and to reduce economically costly waste deposition of the wood ash. However, current legislation restricts the amount of wood ash that can be applied and it is desirable to increase the allowed application dose, if possible, without negative effects on the plantation ecosystems. Here, we applied wood ash in levels corresponding to 0, 3, 9, 15, 30, and 90 t ash ha−1 and monitored the effect of the different ash doses on bryophytes in a Norway spruce (Picea abies) plantation with a dense bryophyte cover dominated by Hypnum jutlandicum, Dicranum scoparium, and Pleurozium schreberi. We used two complementary methods, image analysis, and pinpoint registration during a three-year period. To our knowledge, we are the first to apply this combined effort, which provides a much more exhaustive description of the effects than the use of each method separately. Moreover, the inclusion of a wide range of different wood ash levels enabled us to establish detailed dose-response relationships, which previous authors have not presented. The bryophyte cover decreased with increasing ash level with concomitant changes in species composition. At ash doses above the currently allowed 3 t ha−1, the ash significantly reduced the bryophyte cover, which only re-established very slowly. With increasing wood ash dose, the dominating species changed to Brachythecium rutabulum, Ceratodon purpureus, and Funaria hygrometrica. We conclude that application of more wood ash in spruce plantations than currently allowed will reduce total cover of bryophytes and cause a pronounced change in bryophyte species composition. These changes will in particular harm bryophyte species with specific environmental requirements and generally impair the bryophyte cover as habitat for invertebrates and its economic value for moss harvesting.

Full textAbstract:
We investigated patterns of bryophyte species richness and composition in two forest types of Colombian Amazonia, non-flooded tierra firme forest and floodplain forest of the Caquetá River. A total of 109 bryophyte species were recorded from 14 0.2 ha plots. Bryophyte life forms and habitats were analyzed, including the canopy and epiphylls. Bryophyte species did not show significant differences between landscapes but mosses and liverworts were different and with opposite responses balancing the overall richness. Independence test showed differences in both life form and habitat use distribution between the two forest types with more fan and mat bryophytes species in the floodplains, and more epiphytic liverworts in the tierra firme forest. Correspondence analysis showed differences in the bryophyte species assemblage between the two forest types where they may be responding to the higher humidity provided by the flooding. Despite of, the environmental differences detected, epiphyll species assemblages were not strongly affected. Apparently, epiphyll habitat is stressful enough to hide the environmental differences between the flooded and Tierra firme forests.

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:
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.

Full textAbstract:
Bryophytes are nonvascular plants that have simple structures that are sensitive to environmental changes, and they can, therefore be used as indicators of air quality. The presence of bryophytes in disturbed urban ecosystems, such as residential and industrial areas, indicates that their structures have adapted to survive in such areas. The objective of this study was to compare the bryophyte diversity and air quality indices between a residential area and an industrial area in Jakarta. The research was conducted in the Bona Indah residential area in South Jakarta and the Jakarta Industrial Estate Pulogadung (JEIP) urban forest. Sampling was carried out using the transect method in the residential area and the quadratic method in the urban forest on three different substrates, namely rocks or concrete, soil and tree trunks. The percentage of the epiphytic bryophyte cover was measured using a 10 × 10 cm subplot. Voucher specimens were stored at the Herbarium UI DEP and Herbarium IPB. Twenty-one species of moss and three species of liverwort were found in the two locations. Bryophytes were found on all the substrates in the residential area, but in the urban forest, they were found only on tree trunks and rock/cement substrates. Based on the Shannon–Wiener Index, although both locations had moderate bryophyte diversity, the residential area’s bryophyte diversity was higher than that of the urban forest. The index of atmospheric purity in the residential area was 4.3, indicating a high level of pollution, and it was 0.3 in the urban forest, showing that it was also very polluted.

Full textAbstract:
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.

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.

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.
