ABSTRACTIntroduction Bryophytes can reach levels of coverage sufficient to influence key ecological processes; for example, their water retention capacity can supply an appreciable amount of humidity to forest ecosystems. 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.

ABSTRACTIntroduction The female-biased sex ratio is recurrently observed in bryophyte populations, although the sex ratio of spores is usually balanced. 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.

尽管孢子的性别比例通常是平衡的，但在苔藓植物群体中，女性倾向的性别比例是反复观察到的。几项研究的结果对这一观察结果提出了解释，其中之一是害羞的男性假说。害羞雄性假说预测种群的性别比例在田间是平衡的，但由于雄性植物的性别表达低或缺乏，当性别比例基于性别表达植物的观察时，种群呈现出雌性偏倚。方法利用从巴西季节性干燥热带森林和巴西大西洋森林采集的苔藓苔藓样本，对害羞雄性假说进行了验证。田间性别比通过将芽分类为雄性、雌性或非性别表达来确定。无性别表达苗在培养再生后进一步进行性别表达分析。结果与讨论本研究结果表明，大田地区银心Bryum种群的性别表达率较低，且表达的芽多为雌性。而在无性别表达芽的培养中，雄芽的数量多于田间植株。由于从非性别表达的田间植物中培养的芽中出现了更多的雄性，我们的热带阿根廷蓝的数据倾向于支持害羞雄性的假设。来自湿森林的一些基因型是滑膜的(即在同一个配子体中有雄性和雌性配子体)，表明多倍体。我们感谢Raimundo Guaraci do Carmo Cardoso允许我们在Parque Pedra do Cachorro和Parque das Neblinas的管理人员允许我们在该公园采集阿根廷Bryum。我们还感谢研究人员比安卡·卡利诺夫斯基·卡内斯特拉罗和卢卡斯·马修斯·达·罗查确认了所收集样本的身份。披露声明作者未报告潜在的利益冲突。补充材料本文的补充材料可以在这里访问:https://doi.org/10.1080/03736687.2023.2251776.Supplemental。从巴西干湿森林中采集的52个银角Bryum种群数据摘要。本研究由美国苔藓和地衣学会(ABLS)通过Anderson & Crum Field苔藓学研究奖支持;根据[2021/09506-0]，[2018/24397-0]和[2020/02150-3]拨款，圣保罗州和平与发展基金(FAPESP);以及国家环境保护研究中心Científico e Tecnológico (CNPq)的资助[CNPq: 302849/2021-1]。这项研究的部分经费也由巴西高级经济与社会协调机构(CAPES) -《财务法典》第001号提供。作者简介swagner Luiz dos Santos是巴西坎皮纳斯大学生态学研究生项目的博士生。Kátia Cavalcanti PôrtoKátia Cavalcanti Pôrto，巴西伯南布哥大学植物生物学教授。Joshua Greenwood是美国拉斯维加斯内华达大学的博士后研究员。安迪·戴维斯是美国拉斯维加斯内华达大学生物学专业的一名本科生。Fábio PinheiroFábio Pinheiro是坎皮纳斯大学的植物生物学教授。Lloyd R.

ABSTRACTIntroduction Phymatoceros Stotler et al., one of the 14 extant genera of hornworts, is known from only two species worldwide. During our studies of Indian hornworts, a distinctly variable population was found at Binsar, Uttarakhand, and sharing the same habitat as Phaeoceros himalayensis (Kashyap) Prosk. ex Bapna & G.G.Vyas and Phaeoceros laevis (L.) Prosk.Methods A critical study of the specimens housed at CSIR–NBRI, Lucknow (LWG) was conducted. An SEM study of spores was also carried out to examine their ultramorphological characters.Key results The plants were found to be remarkably characterised by a narrow thallus with prolific stalked tubers arising from the mid-ventral surface; female plants with short involucres; single rounded to irregular chloroplast per cell, without a pyrenoid; and spore distal face with a large, central, single, pitted central hump, and the proximal face with a distinct single dimple on each tetrahedral area between triradiate rays. A detailed morphotaxonomic account is presented, along with detailed SEM observations of spores of the Indian plants.Conclusion Our critical comparative study has revealed that the plants of the newly recorded population belong to the genus Phymatoceros and are distinct from hitherto known species. They are described here as a new species, Phymatoceros binsarensis A.K.Asthana, D.Shukla & Reesa Gupta, and are the first record of Phymatoceros in India. As such, they represent a remarkable and interesting disjunct occurrence of the genus in Asia, separate from its distribution in four other continents (Africa, Europe, and North and South America).

ABSTRACT Introduction California is a biodiversity hotspot for bryophytes, and its northern counties are among the most endemic-rich areas for bryophytes in North America. 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. The richness of the bryophyte flora of California provides a clear warrant for future research.

Introduction The bryophyte flora of Hungary was relatively well studied during the twentieth century, but data on the present-day frequency and geographical distribution of Hungarian bryophytes are lacking. 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.

ABSTRACT Introduction The aims of this study were to help clarify the identification of Sphagnum balticum in Britain, to review its distribution, and to investigate the possible presence of hybrids between it and either S. cuspidatum or S. fallax. 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. Conclusions Sphagnum balticum is a very rare species in Britain that has undergone a decline due to habitat destruction and alteration. It is presently known to survive at only three sites, of which two are within protected areas.
