The variation in biomass and diversity of epiphytic liverwort species in a Mexican cloud forest (CF) in the state of Hidalgo was estimated along elevation and latitude gradients, as was the relationship between epiphytic liverwort structural attributes and environmental factors.Methods Liverwort species were sampled in three municipalities with CF in Hidalgo State, at elevations of 1345–2019 m. In each municipality, two 0.1 ha plots were located at the two extremes of the gradient. For each of 10 trees per plot, three 10 × 10 cm areas of bark were selected as microplots, and from each microplot, samples of liverwort were obtained to determine structural data for the liverworts.Key results Species diversity was highest at the upper elevation level (1985–2001 m), and lowest at the lower elevation level (1345–1375 m). The highest dry and saturated weight values (15.20 g and 83.30 g, respectively) were found at lower elevations, and the lowest (11.78 g and 60.04 g, respectively) at high elevations.Conclusion Species diversity was positively related to elevation gradient, and species biomass decreased gradually with elevation. Beta diversity values were not associated with geographical distance between sites. Local factors, such as light input, available area, phorophyte species, humidity and temperature, may have more influence on the growth of epiphytic liverworts than elevation or geographical distance.KEYWORDS: Bryophyteselevationliverwortsspecies diversitytemperate forests AcknowledgementsWe gratefully acknowledge the Consejo Nacional de Humanidades, Ciencias y Tecnologías (CONAHCYT) for the scholarship granted to the first author to carry out postgraduate studies.

The results of several studies have suggested explanations for this observation, one of which is the shy male hypothesis. The shy male hypothesis predicts that the sex ratio of populations is balanced in the field, but due to a low or lack of sex expression of male plants, the populations present a female bias when the sex ratio is based on observations of sex-expressing plants.Methods We tested the shy male hypothesis using samples of the moss Bryum argenteum collected from Brazilian seasonally dry tropical forests and the Brazilian Atlantic Forest. Field sex ratios were determined by classifying shoots as male, female, or non–sex-expressing. Non–sex-expressing shoots were further analysed for sex expression after culture regeneration.Results and discussion Our results showed that populations of Bryum argenteum in the field had a low rate of sex expression, and that most of the shoots expressed were female. However, when shoots without sex expression were cultured, a greater number of male shoots were observed compared with in the field plants. Because more males appeared in the shoots cultured from non–sex-expressing field plants, our data for tropical B. argenteum tend to support the shy male hypothesis. Some genotypes from the wet forest were synoicous (i.e. had male and female gametangia in the same gametoecia), suggesting polyploidy.KEYWORDS: Dioicygametangia productionlabile sexmosssex expressionsex ratio AcknowledgementsWe thank Raimundo Guaraci do Carmo Cardoso for allowing us to collect samples of Bryum argenteum in Parque Pedra do Cachorro, and the management of Parque das Neblinas for allowing us to collect in that park.

Having 29 species in California, Grimmia Hedw. is the third richest moss genus in the state, but recent fieldwork suggests that this number is an underestimate. The identity of some specimens endemic to the Klamath Mountains of California and previously identified as G. brevirostris R.S.Williams remains unclear, and they potentially represent a new species. Two further specimens of Grimmia from Siskiyou County, California, do not correspond to any species described so far. Here we present morphological and phylogenetic arguments for recognising these plants as two new moss species in the genus Grimmia subg. Orthogrimmia Schimp. Methods Morphological characters across potential new species were reviewed and compared with those of related species. Phylogenetic analyses based on the plastid trnS–trnF and nuclear ITS regions were conducted. Key results and conclusions The molecular and morphological analyses revealed two new species of Grimmia for California, which are described and illustrated: G. shevockii J.Muñoz, I.Solano & D.Quandt and G. insolita J.Muñoz, I.Solano & D.Quandt. The former is resolved in a monophyletic clade with high support, whereas the latter has incongruent positions in the plastid and nuclear phylogenies, thus it is hypothesised that it could have a hybrid origin. Both of the two new species and G. hamulosa undoubtly pertain to Grimmia.

We present here our preliminary results based on recent fieldwork and herbarium studies. Methods We recorded bryophyte occurrences in grid cells (quadrants) of approximately 5.5 × 6 km. Frequency was determined based on the number of quadrants, and geographical distribution evaluated in terms of the 19 administrative units (counties) of the country. To investigate correlations between species richness and relevant environmental drivers, statistical analyses were carried out. Key results A total of 698 bryophyte taxa (2 hornworts, 151 liverworts and 545 mosses) have been found in the territory of Hungary. For each of the 637 taxa that have been observed since 1973, one of five frequency classes (very common, common, sporadic to frequent, rare, and very rare) has been assigned based on the relevant number of field records or herbarium specimens. Additionally, tabular distributional information (occurrence in each of the 19 counties) is presented for each taxon. In the statistical evaluation of the geographical distribution data, the elevational range and the size of the surveyed area were positively correlated with bryophyte richness, whereas arable land cover was negatively correlated. Conclusions Although the survey was not uniform or complete across the different counties, the results support some robust bryogeographical theories. We hope to have the opportunity in the near future to compile a new Hungarian bryophyte Red List, partly based on these national frequency data.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":"45 1","pages":"121 - 148"},"PeriodicalIF":1.9,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41798020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods All sites at which Sphagnum balticum has been recorded recently in Britain were visited in 2020, and a search made for it and other species with which it could be confused, together with possible hybrids. Samples were collected when suitable material was found. DNA was extracted from 31 shoots, each representing one field sample. Fifteen microsatellites that have been developed for Sphagnum species were amplified and genotyped. The genetic structure of the data was investigated using principal coordinate analysis and cluster analysis. Results The results of the genetic analysis support the recognition of four taxa, which corresponded to four morphologically identified taxa: Sphagnum angustifolium, S. balticum, S. cuspidatum and S. fallax. There was no evidence of hybrids. Over-recording of S. balticum has occurred in Britain due to confusion with some forms of S. cuspidatum and S. fallax, which can exhibit some morphological characters usually used to identify S. balticum. An illustrated identification key is provided to help solve this problem.
