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.

Introduction. In the Iberian Peninsula, Schistostega pennata is a rare, acidophilic, Holarctic moss with a characteristic glowing protonema when illuminated by sunlight. It is typically found in dark and humid habitats and is categorised as Threatened or Near Threatened on the Iberian Red Lists. The main aim of this study was to improve knowledge of the distribution, ecology and conservation of S. pennata on the Iberian Peninsula.

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.

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.
