Abstract:
The tropical zone of Mount Ungaran is a tropical forest which are rich in diversity of flora. One of them is Bryophytes. Most of the Bryophytes of tropical forest are epiphytes. The largest group of Bryophytes is mosses (Bryophyta). However, research about epiphytic mosses in this area are sparse, so it is only a few information given about epiphytic mosses in this area. The aim of this research was to identify epiphytic mosses in tropical zone of Mount Ungaran altitudes 750, 980, and 1.100 meters above sea level, and also to determine the frequency attendance of species in this study site. This research was conducted in April through November 2012. Specimens was carried out at Laboratory of Ecology and Biosistematics, Department Biology, Faculty of Science and Mathematics, Diponegoro University, Semarang, Indonesia. The results shown there are 35 species mosses. Diversity of epiphytic moses most commonly found at altitude 1.100 meters above sea level, as many as 17 species, while at altitudes 750 and 980 meters above sea level was found 15 species. Family Hypnaceae is the family with highest number of species (6 species) and has highest total amount of frequency attendance by 16,13%. Hypnum plumaeforme and Luisierella barbula were the species which had wide distribution. Both of them were found at all three altitudes. Species with the highest total amount of frequency attendance is Hylocomium splendens from family Hylocomiaceae with total amount by 9,68%. Key words : epiphytic mosses, Mount Ungaran, tropical zone

Abstract:
A composition of 16 lipid samples of sphagnum and true mosses (Bryales) growing at an average annual temperature ranging from -9.1 °C to 1.5 °C is investigated by gas chromatography-mass spectrometry. The individual composition and content of n-alkanes, fatty n-acids and their esters, n-alkane-2-ones, aldehydes, farnesylfuranes, polycyclic aromatic hydrocarbons (PAHs), tocopherols, squalene, steroids, sesqui-, di- and triterpenoids of these mosses are determined. True mosses differ from sphagnum mosses in their lower content of n-alkanes, n-alkan-2-ones, n-aldehydes, tocopherols and cyclic terpenoids, and a higher content of PAHs. Campesterol prevails among steroids of true mosses, while stigmasterol and sitosterol dominate in sphagnum mosses. Sitosterol prevails in sphagnum mosses growing in areas with a negative average annual temperature. An increase in the temperature of the habitat results in a decrease in the relative content of n-alkanes with odd number of carbon atoms in the molecule in true mosses, and a slight decrease in their average chain length in sphagnum mosses. It is shown that terpenoids are the most dependent on natural habitat conditions of mosses. This is indicated by the content of squalene, sesqui- and diterpenoids, the ratio of hydrocarbons to oxygen-containing structures of cyclic triterpenoids, and that of compounds from series of perhydropicene and cyclopentapeperhydrochryzene. The increased humidity of habitat of a moss eliminates the effect of temperature. The stability of composition of n-alkanes and n-alkan-2-ones of sphagnum mosses developing under various conditions makes it possible to consider these compounds as potential chemotaxonomic markers of sphagnum mosses in peat deposits.

Abstract:
The analysis of the taxonomic composition and abundance of mosses in the larch forests of the Chita region (in the Olengui and Beklemishevsky forest areas) of the Trans-Baikal Territory is given. Leaf stemmed mosses (real mosses) are the largest class of mosses. The purpose of this work is the taxation of moss cover in the forests of the Trans-Baikal Territory. Mosses were determined in the laboratory by the traditional anatomical and morphological method. A ceno-tic characteristic is given for each moss species, distribution and occurrence are indicated. In the bryoflora of two forest areas of the Trans-Baikal Territory, most mosses are defined as widespread species growing in several plant zones of the Holarctic. Such species, as a rule, are identified as the dominant moss cover of plant communities. In the forests of the Trans-Baikal Territory, mosses do not form a continuous cover. The harsh and dry climate causes desiccation of sandy and rocky-gravelly soils. Under the canopy of such forests there are no conditions for the development of moss cover. Therefore, the species composition of mosses is poor, and the projective coverage on the accounting sites ranges from 10 % to 45 %. In forest areas, mosses grow in open habitats: on wastelands, cuttings, burning, soil outcrops, sometimes on rocks and dead wood.

Abstract. Mosses, as major components of later successional biological soil crusts (biocrusts), play many critical roles in arid and semiarid ecosystems. Recently, some species of desiccation-tolerant mosses have been artificially cultured with the aim of accelerating the recovery of biocrusts. Revealing the factors that influence the vegetative propagation of mosses, which is an important reproductive mode of mosses in dry habitats, will benefit the restoration of moss crusts. In this study, three air-dried desiccation-tolerant mosses (Barbula unguiculata, Didymodon vinealis, and Didymodon tectorum) were hermetically sealed and stored at five temperature levels (0, 4, 17, 25, and 30 °C) for 40 days. Then, the vegetative propagation and physiological characteristics of the three mosses were investigated to determine the influence of storage temperature on the vegetative propagation of desiccation-tolerant mosses and the mechanism. The results showed that the vegetative propagation of the three mosses varied with temperature. The most variation in vegetative propagation among storage temperatures was observed in D. tectorum, followed by the variation observed in B. unguiculata. In contrast, no significant difference in propagation among temperatures was found in D. vinealis. The regenerative capacity of the three mosses increased with increasing temperature from 0 to 17 °C, accompanied by a decrease in malondialdehyde (MDA) content, and decreased thereafter. As the temperature increased, the chlorophyll and soluble protein contents increased in B. unguiculata but decreased in D. vinealis and D. tectorum. As to storage, the MDA and soluble sugar contents increased after storage. The MDA content of the three mosses increased at each of the investigated temperatures by more than 50 % from the initial values, and the soluble sugar content became higher than before in the three mosses. The integrity of cells and cell membranes is likely the most important factor influencing the vegetative propagation of desiccation-tolerant mosses. A 40-day storage period caused cell injury. Our results suggest that storage temperature can enhance or suppress such injury and change the regenerative capacity of the three mosses. The data indicate that the suitable storage temperature is 4 °C for B. unguiculata and 17 °C for both D. vinealis and D. tectorum.

Abstract:
Mosses have often been used for biomonitoring because of their diversity of habitats, structural simplicity, and rapid multiplication rate. This research aimed to study the tolerance of heavy metal in 3 species of terricolous mosses i.e., Barbula consanguinea, Hyophila apiculata, and H. involuta. The gametophores of mosses were immersed at 4 concentrations of each of the heavy metals Cd, Pb, and Zn as well as in controls with no heavy metal. After 10, 20, and 30 days of exposure, mosses were extracted for chlorophyll-a in ethanol. The extracted chlorophyll-a was analyzed by spectrophotometer at 664 nm. The results revealed that the amount of chlorophyll-a in all species decreased with increasing concentrations of Cd, Pb, and Zn. The degree of metal toxicity for all species was Cd > Pb > Zn. By comparing the ratio of extracted chlorophyll-a in heavy metal-treated mosses to chlorophyll-a extracted in control mosses, the tolerance against 3 heavy metals in 3 mosses was H. involuta ≥ H. apiculata > B. consanguinea. Possibly, H. involuta can be used for biomonitoring of heavy metals in contaminated environments in the future. HIGHLIGHTS Mosses are often used for biomonitoring of heavy metal pollution because of their habitat diversity, structural simplicity, and rapid growth Three Thai mosses treated with Cd, Pb, and Zn showed a trend of a decrease in chlorophyll-a content with increasing concentrations of the metals The degree of metal toxicity for the mosses was Cd > Pb > Zn Among the three moss species, Hyophila involuta may be used for biomonitoring of heavy metals in contaminated environments in the future GRAPHICAL ABSTRACT

Abstract:
Internal specialized conducting tissues, if present, are restricted to the gametophytic generation in liverworts while they may occur in both generations in mosses. Conducting tissues are unknown in the anthocerotes. Water–conducting cells (WCCs) with walls perforated by plasmodesma–derived pores occur in the Calobryales and Pallaviciniaceae (Metzgeriales) among liverworts and in Takakia among mosses. Imperforate WCCs (hydroids) are present in bryoid mosses. A polarized cytoplasmic organization and a distinctive axial system of microtubules is present in the highly specialized food–conducting cells of polytrichaceous mosses (leptoids) and in less specialized parenchyma cells of the leafy stem and seta in other mosses including Sphagnum . A similar organization, suggested to reflect specialization in long–distance symplasmic transport of nutrients, also occurs in other parts of the plant in mosses, including rhizoids and caulonemata, and may be observed in thallus parenchyma cells of liverworts. Perforate WCCs in the Calobryales, Metzgeriales and Takakia , and hydroids in bryoid mosses, probably evolved independently. Because of fundamental differences in developmental design, homology of any of these cells with tracheids is highly unlikely. Likewise, putative food–conducting of bryophytes present highly distinctive characteristics and cannot be considered homologous with the sieve cells of tracheophytes.

Abstract:
Many factors may affect the survival and establishment of a moss’s vegetative propagules after dispersal, but little is known about the species-specific nature of the response. This study examined the survival and regeneration of gametophore fragments after exposure to temperature changes for three boreal forest mosses from different habitats: Dicranum polysetum, Orthotrichum obtusifolium, and Pleurozium schreberi. Fragments were cultured on water agar and the survival and regeneration responses were recorded. Logistic regression analyses and AIC modeling evaluated the association between the response with the size of the gametophore fragments exposed to five abrupt or gradual temperatures for up to six exposure durations. The increased survival and regeneration was best explained when species were exposed to gradual, rather than abrupt temperatures; lower, rather than higher temperatures; and when the fragments had larger, rather than smaller sizes. The mosses had different survival and regeneration responses that may be species-specific, including clonal growth via the production of gametophore branches and protonemata, or mostly protonemata, even when exposed to elevated temperatures.

Abstract:
Mosses or bryophytes, belonging to the lower plants, can grow on higher plants (as epiphyte), stone (epilytic), bark (corticolus), and the surface of the soil. One of the important places in East Java and having a variety of potential mosses is Tumpak Sewu Waterfall. In this place, moss grows well because of the condition of the nature, humidity, and abundant air. This study aimed to identify and calculate the population of mosses at Tumpak Sewu Waterfall, Lumajang, East Java. The research sampling has been performed along hiking trip, riverside and tourist area of Tumpak Sewu Waterfall. Quadratic method with grid lines with a plot size of 1x1 m² on the right and left sides of the river was used to collect and calculate mosses population. Mosses identification was performed using mosses identification key. The population data obtained from this study were analyzed by calculating Frequency, Dominancy and Important Value Index (IVI). This study found 7 species of mosses in which 3 species belong to Family Marcahntiaceae, 2 species belongs to Bryaceae and 1 species belongs to Pottiaceae and Anthocerotaceae, respectively. The highest of IVI value is specimen K2, corresponds to Pohlia flexuosa W.J. Hooker, with 78.178%, and the lowest of IVI value is specimen K6, corresponds to Marchantia sp. with 4.524%. It can be concluded that Tumpak Sewu Waterfall has diversity for mosses that could be useful to conserve Indonesian natural resources especially lower plants.

Abstract:
In this paper, we present an analysis of the pollution of surface water and air by the heavy metals: Mn, Fe, Ni, Cu, Zn, Cd and Pb in the area of the smelter in Ozimek (Opolskie Voivodeship, Poland). The marine algae Palmaria palmata was exposed in the Mała Panew River, and three species of forest mosses: Pleurozium schreberi, Sphagnum fallax and Dicranum polysetum were also applied. Active biomonitoring was also carried out using P. schreberi mosses to assess air pollution, since the area and the river are influenced by the smelter’s activities. Analytes were determined by atomic absorption spectrometry. Student’s T-test and Mann–Whitney U test were used to assess the significance of differences in elemental concentrations between algae and mosses. Forest mosses were found to have comparable sorption properties to algae under laboratory conditions. During exposure in the river, statistical significance was found between these matrices. The results of water biomonitoring studies using forest mosses offer the possibility of their inclusion in aquatic ecosystem monitoring as an alternative to existing classical surface water biomonitors. Perspectively, attention should be paid to comparing the sorption properties of aquatic species with forest mosses in order to optimize the water biomonitoring system using mosses.

Full text
Abstract:
Environmental context Mosses and lichens are widely distributed in montane forests and their important role in global biogeochemical cycles has been increasingly recognised. This study of mercury accumulation and sources in mosses and lichens, using mercury isotopic data, provides evidence that they promote atmospheric mercury deposition in these forests, which is an important function that should be incorporated into current mercury mass balance budgets for forests. Rationale Mosses and lichens, which are widely distributed in montane forests, are often used to monitor the atmospheric mercury (Hg) depositions. In this study we hypothesised that atmospheric Hg uptake by mosses and lichens could greatly promote Hg depositions in montane forests. Methodology We comprehensively determined the Hg concentration and isotopic signatures of various species of mosses and lichens in a subtropical montane forest, to quantify the Hg accumulation, influencing factors and potential Hg depositions induced by mosses and lichens. Results Our results show that the higher Hg concentrations in mosses than in lichens are mainly due to their species-specific, morphological and physiological differences. Hg isotopic mixing model results display that uptake of atmospheric elemental Hg (Hg0) contributes 89.2 ± 22.8% of Hg in mosses and 88.4 ± 24.4% in lichens. The lichens growing on trees have a lower atmospheric Hg0 source contribution than on the ground (61.3 ± 42.5% versus 93.6 ± 10.0%) because of the elevated rainfall Hg uptake on trees. The Hg storage in live moss and lichen is 28.0 ± 16.5 and 0.9 ± 1.0 μg m−2, respectively. Given the 1–2-year lifespan of moss, the moss induced atmospheric Hg deposition is almost equivalent to litterfall Hg deposition which was previously used as a proxy for atmospheric Hg0 deposition in forests. Discussion Overall, we suggest mosses and lichens play an important role in atmospheric Hg depositions and recommend more research in montane forests.

Full text
Abstract:
Polycyclic aromatic hydrocarbons (PAHs), as the main components of petroleum hydrocarbons (PHCs), are carcinogenic organic pollutants that occur widely in the atmospheric environment with increasing concentration. Moreover, PAHs are widespread all over the world due to their high volatility and long-range transport potential. The monitoring of atmospheric PAHs is often limited by working conditions, especially around oil field operation areas and other industrial areas. Mosses (Bryophyta), the most sensitive atmosphere pollution indicators, can be easily collected and have been used to monitor atmospheric pollutants including PAHs. Thus, characteristics and influencing factors of mosses’ absorption and accumulation of PAHs in the atmosphere were discussed, and the application of mosses in the biomonitoring of atmospheric PAHs were summarized. Biomonitoring mosses include Dicranum scoparium, Hypnum cupressiforme, Thamnobryum alopecurum, Thuidium tamariscinum, Hylocomium splendens, Pleurozium scheberi, etc. Currently, the main methods for monitoring PAHs by mosses are biomonitoring with the chemical analysis method, the index of atmospheric purity (IAP) method, the ecological survey method, and the Moss-bag technique. Biomonitoring of atmospheric PAHs using mosses has a relatively wide range of prospects.

The list of sphagnum mosses of the swamped part of Lake Germanovskoe catchment area («Valaam Archipelago» Natural Park) is provided for the first time. The Valaam Archipelago is located in the northern part of Lake Ladoga, in Republic of Karelia. The largest Valaam Island takes over 2/3 of the archipelago area — 27.8 km2. The ecological characteristics of sphagnum mosses are discussed. A detailed investigation of ecotopes and plant communities dominated by sphagnum mosses was conducted. The study of tree stands, herb and moss layers, soils and analysis of Lake Germanovskoe hydro-chemical characteristics were carried out to define the conditions of Sphagnum habitats. Different sphagnum mosses dominate in ecotopes with various regime of moisture. The swamped part of Lake Germanovskoe catchment area is determined as having mesotrophic characteristics. Аnalysis of the ecological characteristics of sphagnum mosses shows the same result.

Full text
Abstract:
The nucleotide variation of a noncoding region between the atpB and rbcL genes of the chloroplast genome was used to estimate the phylogeny of 11 species of true mosses (subclass Bryidae). The A+T rich (82.6%) spacer sequence is conserved with 48% of bases showing no variation between the ingroup and outgroup. Rooted at liverworts, Marchantia and Bazzania, the monophyly of true mosses was supported cladistically and statistically. A nonparametric Wilcoxon Signed-Ranks test Ts statistic for testing the taxonomic congruence showed no significant differences between gene trees and organism trees as well as between parsimony trees and neighbor-joining trees. The reconstructed phylogeny based on the atpB-rbcL spacer sequences indicated the validity of the division of acrocarpous and pleurocarpous mosses. The size of the chloroplast spacer in mosses fits into an evolutionary trend of increasing spacer length from liverworts through ferns to seed plants. According to the relative rate tests, the hypothesis of a molecular clock was supported in all species except for Thuidium, which evolved relatively fast. The evolutionary rate of the chloroplast DNA spacer in mosses was estimated to be (1.12 ± 0.019) × 10-10 nucleotides per site per year, which is close to the nonsynonymous substitution rates of the rbcL gene in the vascular plants. The constrained molecular evolution (total nucleotide substitutions, K approximately 0.0248) of the chloroplast DNA spacer is consistent with the slow evolution in morphological traits of mosses.

Abstract:
Gunung Senyum Recreational Forest harbours 59 species, two subspecies and five varieties of mosses in 32 genera and 16 families that had been identified from a total of 589 specimens collected from the area. These figures represent 11.8% out of the 558 taxa, 20.2% out of the 158 genera and 34.7% out of the 46 families of mosses reported for Peninsular Malaysia. The total also represents 14.9% of the 442 taxa, 24.0% of the 133 genera and 40.0% of the 40 families of mosses recorded in Pahang. The largest family of mosses found in this limestone forest is Calymperaceae followed by Fissidentaceae. There are two new records for Pahang, Calymperespallidum Mitt. and Taxitheliumbinsteadii Broth. & Dixon. The analysis of species similarities of mosses found in the study area with some other selected areas showed that Gunung Senyum Recreational Forest had a high percentage of species similarity with Perlis State Park at Wang Kelian, another limestone forest, at 38%. Corticol is the main habitat utilised by mosses in Gunung Senyum Recreational Forest with 47 taxa, followed by the lignicol and calcicol each with 35 and 26 taxa, respectively.

Abstract. Sphagnum peatlands are important ecosystems in the methane cycle. Methanotrophs living in and on the Sphagnum mosses are able to act as a methane filter and thereby reduce methane emissions. We investigated in situ methane concentrations and the corresponding activity and diversity of methanotrophs in different Sphagnum dominated bog microhabitats. In contrast to the Northern Hemisphere peat ecosystems the temperate South American peat bogs are dominated by one moss species; Sphagnum magellanicum. This permitted a species-independent comparison of the different bog microhabitats. Potential methane oxidizing activity was found in all Sphagnum mosses sampled and a positive correlation was found between activity and in situ methane concentrations. Substantial methane oxidation activity (23 μmol CH4 gDW−1 day−1) was found in pool mosses and could be correlated with higher in situ methane concentrations (>35 μmol CH4 l−1 pore water). Little methanotrophic activity (<0.5 μmol CH4 gDW−1 day−1) was observed in living Sphagnum mosses from lawns and hummocks. Methane oxidation activity was relatively high (>4 μmol CH4 gDW−1 day−1) in Sphagnum litter situated at depths around the water levels and rich in methane. The total bacterial community was studied using 16S rRNA gene sequencing and the methanotrophic communities were studied using a pmoA microarray and a complementary pmoA clone library. The methanotrophic diversity was similar in the different habitats of this study and surprisingly comparable to the methanotrophic diversity found in peat mosses from the Northern Hemisphere. The pmoA microarray data indicated that both alpha- and gammaproteobacterial methanotrophs were present in all Sphagnum mosses, even in those mosses with a low initial methane oxidation activity. Prolonged incubation of Sphagnum mosses from lawn and hummock with methane revealed that the methanotrophic community present was viable and showed an increased activity within 15 days. The high abundance of methanotrophic Methylocystis species in the most active mosses suggests that these might be responsible for the bulk of methane oxidation.

Abstract:
In investigating the extent of genetic diversity in Antarctic mosses the RAPD technique has proven especially useful in demonstrating that these mosses exhibit extensive genetic variation (levels being similar to those in temperate regions), and that within-colony variation is apparently caused not only by immigration and establishment of propagules from elsewhere, but also by mutagenesis. Dispersal of these mosses can also be followed using the RAPD technique; both short-distance dispersal by wind or water (depending on the moss species) and longer distance dispersal by wind across the ice cap has been demonstrated. Relationships with temperate mosses of the same species are being investigated to determine the origins of Antarctic populations. Genetic technology is also facilitating the taxonomic identification of moss specimens which cannot be identified morphologically due to phenotypic plasticity in Antarctica. Together, these genetic studies are starting to provide information of fundamental scientific importance for understanding the evolution, origins and dispersal mechanisms of Antarctic mosses, and their response to climate change.

Abstract:
Tropical cloud forests are characterized by abundant and biodiverse mosses which grow epiphytically as well as on the ground. Nitrogen (N)-fixing cyanobacteria live in association with most mosses, and contribute greatly to the N pool via biological nitrogen fixation (BNF). However, the availability of nutrients, especially N and phosphorus (P), can influence BNF rates drastically. To evaluate the effects of increased N and P availability on BNF in mosses, we conducted a laboratory experiment where we added N and P, in isolation and combined, to three mosses (Campylopus sp., Dicranum sp. and Thuidium peruvianum) collected from a cloud forest in Peru. Our results show that N addition almost completely inhibited BNF within a day, whereas P addition caused variable results across moss species. Low N2 fixation rates were observed in Campylopus sp. across the experiment. BNF in Dicranum sp. was decreased by all nutrients, while P additions seemed to promote BNF in T. peruvianum. Hence, each of the three mosses contributes distinctively to the ecosystem N pool depending on nutrient availability. Moreover, increased N input will likely significantly decrease BNF associated with mosses also in tropical cloud forests, thereby limiting N input to these ecosystems via the moss-cyanobacteria pathway.

Abstract:
Mosses are sensitive and precise bioindicators of heavy metals contamination of the environment. They accumulate in their tissues large amounts of these elements than do higher plants. The aim of this study was to present the influence of environmental pollution on quantitative relations of heavy metals and cationic equilibrium in tissues of mosses: <em>Pleurozium schreberi</em>, <em>Hylocomium splendens</em> and <em>Hypnum cupressiforme</em>. Twelve sampling sites were selected in the area of Lower Silesia (Poland), diverse in respect of pollution degree determined for dust fall and contents of metals in dust. The contents of Ca, K, Na, Mg, Al, Mn, Fe, Cu, Pb, Ni, Cd, and Zn have been examined in the mosses. Significant differences in the elements contents of mosses between the examined sites, and between moss species were found. This differentiation affects the cationic equilibrium. It is expressed by weighed sum of square roots of relative cation concentrations. The quantitative relations between contents of elements in mosses depended on species and pollution level. These relations and accumulation of metals in moss tissues is the indicator of environmental pollution, which influences the ecological condition of mosses and their occurrence in the given area. The air contaminated by heavy metals causes stress and the decline of moss populations, and can be of significance for their survival. The results of this type of investigations are of importance for the active protection of mosses and their biotopes.

Abstract: The varied group of terrestrial plants known as bryophytes is tiny in stature but has significant ecological effects. The biggest group of terrestrial plants, excluding flowering plants, they have over 23,000 known species worldwide. Mosses, hornworts, and liverworts are among the three phylogenetically separate lineages that make up the category. Mosses are typically regarded as a "key group" in our comprehension of the phylogenetically relatedness and origin of contemporary land plants (embryophytes). Bryophytes are able to live in a wide range of settings and have various growth habits. Although, mosses exhibit high species diversity, a major limitation in using mosses as study organisms has been the lack of basic floristic, ecological, and alpha-taxonomical knowledge of plants in many regions

Abstract The aim of biomonitoring is assessment of environment condition. Biomonitoring studies with the use of mosses focus mainly on analytes accumulation and determining elements’ concentrations in the study area. It is often forgotten that a bioindicator should be alive during biomonitoring studies (which can be determined by, e.g., analysis of chlorophyll content). The objective of the carried out research was an assessment of the influence of selected heavy metals concentration: Ni, Cu, Zn, Cd and Pb accumulated by Pleurozium schreberi mosses during 3-month exposition within active biomonitoring, on their vitality, assessed by an analysis of a and b chlorophyll concentrations. The studies were also carried out in laboratory conditions, where the content of the dyes was determined with the aid of a UV-Vis spectrophotometer, in mosses reacting with solutions of various concentrations of the analysed metals. The content of elements in mosses after exposition and in solutions prior and after sorption were determined with the use of atomic absorption spectrometry (AAS) in a flame atomiser. After the carried out studies it was determined that mosses, during 12-week long exposition, accumulated heavy metals, which did not clearly influence the changes in chlorophyll content. The carried out studies prove that heavy metals are not the only and determining factor, which influences chlorophyll content in mosses as well as the bioindicator’s vitality in the conditions of environmental stress.

Abstract Background and Aims Nutrient resorption from senescing tissue is a key mechanism for plants to conserve nutrients, and can affect the nutrient dynamics of ecosystems. Yet, our limited knowledge of nitrogen (N) resorption and release from mosses hampers our understanding of the role of mosses as N sources and, thereby, N cycling in moss-dominated ecosystems. The aims of this study were to estimate N resorption efficiency (NRE) of two moss species, identify the pathways of N release from the mosses and to provide a better understanding of N cycling and budgeting strategies of mosses. Methods The dynamics of N allocation along annual moss segments of two dominant moss species (Actinothuidium hookeri and Hylocomium splendens) were assessed in old-growth fir forests using an in situ15N tracer experiment. Key Results The NRE of A. hookeri and H. splendens was 61 and 52 %, respectively. While the mosses lost 23 and 33 % N from live tissues via leaching, 15 and 14 % of N remained in senesced tissues (&gt;3 years old) in A. hookeri and H. splendens, respectively. Conclusions Both mosses resorbed the majority of their tissue N, but a considerable amount of N was lost from live segments. Our results highlight the crucial role mosses play as N sinks in ecosystems, since N retention (resorbed and sequestered in senescent tissue) outweighed N loss via leaching. However, the sink strength depends on temperature and precipitation, which will change in a future climate. The values for NRE, leaching, etc. estimated here can help improve biogeochemical models aiming to complete N budgets for moss-abundant ecosystems.

Abstract:
(1) Background: Detailed diversity information regarding terrestrial mosses in a tropical forest ecosystem and an understanding of the drivers behind moss distribution provide crucial data for the management and conservation of forest ecosystems. Mosses are critical components of tropical forest ecosystems due to their high diversity and biomass, and they also fulfill essential ecological functions. Here, we report the first study into the relative importance of vegetation types and elevational gradient for the diversity, distribution and community structure of terrestrial moss species in southern China. (2) Methods: Five elevations spaced 200 m apart in the tropical mountain forest on the northern aspect of Tai Mo Shan were selected. The diversity, distribution, and geographical patterns of terrestrial mosses in response to altitudinal changes were examined. Differences in the biotic variables of terrestrial mosses between elevations were tested using a one-way ANOVA. Curve estimation regression models were used to describe the responses of the biotic variables to the elevation gradient. Canonical correlation analysis (CCA) was performed to identify and measure the associations among biotic variables of terrestrial mosses and abiotic environmental factors. (3) Results: Fifty-three terrestrial moss species belonging to 20 families and 31 genera were recorded along the altitudinal gradient on Tai Mo Shan. Microclimate factors including dew point and rainfall were strongly associated with the cover and thickness of the ground moss species. There were no obvious richness changes of terrestrial mosses along the elevation gradient. In total, 33 of the 51 species were tropically distributed, 14 species were found across East Asia and the tropical regions, 10 species had an East Asian pattern and 8 were temperate species. (4) Conclusions: Vegetation types significantly affect the diversity and distribution of terrestrial moss species. Although they are influenced by the East Asian and temperate climate with frequent human activities, terrestrial mosses on Tai Mo Shan are primarily tropical in nature. Forest conservation and restoration should be implemented to sustain and improve the diversity of terrestrial mosses and understory plants on Tai Mo Shan, especially at higher elevations.

Abstract:
Abstract Aims Mosses are dominant in many ecosystems where nutrients from deposition are one of the main nutrient sources. However, it is difficult to evaluate mosses’ role in nutrient cycling without knowledge of how mosses use deposited nutrient inputs. To fill this gap, the present study aims to investigate: (i) how nitrogen (N) and phosphorus (P) concentrations of new-grown segments change along a gradient of N or P amount in a pulse treatment? (ii) how do a pulse of major nutrient (N or P) affect N or P translocation rate along a moss shoot? and (iii) to what extent do N or P translocation rates link to nutrient status of the new-grown segments of mosses? Methods We measured N and P concentrations of segments with different ages in two dominant forest floor mosses, Actinothuidium hookeri and Hylocomium splendens, on 8 days and 1 year after N and P pulse treatment with an in situ experiment in a subalpine fir forest in eastern Tibetan Plateau. Important Findings Both mosses were efficient in taking up nutrients from a pulse of either N or P. Nitrogen and P concentrations of new-grown segments were affected by nutrient pulse treatments. These N and P concentration changes were attributed to the initial N and P concentration of the young segments harvested 8 days after nutrient pulse treatments, suggesting that the captured nutrients were reallocated to the new-grown segments via translocation, which was largely controlled by a source–sink relationship. While no significant relationship was found between N translocation rate and N:P ratio of the new-grown segments, P translocation rate explained 21%–23% of the variance of N:P ratio of the new-grown segments, implying importance of P transport in supporting the new-grown sections. These results suggest that nutrient (N, P) translocation is a key process for mosses to utilize intermittent nutrient supply, and thus make mosses an important nutrient pool of the ecosystem.

Abstract:
The mining of manganese brings excellent wealth to humankind. However, it destroys the ecological environment, mainly manifested as heavy metal pollution and vegetation destruction. The restoration of ecological vegetation in manganese mining areas has become an important work after mineral exploitation. The effect of bryophytes on ecological restoration in mining areas is irreplaceable. The bryophytes diversity and its pioneering role in two types of manganese waste residue areas were investigated in Guizhou province, China. The results showed that there were 24 species of mosses in mine waste slag areas, and all of them belonged to 6 families and 15 genera; the species Gymnostomum subrigidulum, Pohlia gedeana, and Bryum atrovirens were the dominant mosses. There were 6 species of mosses in electrolytic manganese slag areas, and all of them belonged to 5 families and 5 genera. The dominant moss was B. atrovirens. The bryophytes diversity in the electrolytic manganese slag areas with lower pH was poorer than that in mine slag areas. The accumulation of heavy metals in mosses showed that B. atrovirens collected from two types of areas had a strong ability to accumulate Mn with the cumulants 5588.00 μg/g and 4283.41 μg/g, respectively. All mosses had a strong enrichment ability to Cd. It indicated that mosses had strong tolerance to heavy metals. Bryophytes increased the available nutrients and bacterial community diversity of mosses growth substrates in two types of areas. Besides, we studied the relationships between bacterial community structure and soil factors. The main soil factor affecting the bacterial community structure was available nitrogen (AN) in mine waste slag areas, while it was pH in the electrolytic manganese residue areas. The systematic study suggested that bryophytes increased the available nutrients and the microbial community diversity of the growth substrates in manganese waste residue areas, which provided the basic conditions for the growth of vascular plants.
