Knowledge of the sporophyte maturation cycle is also incomplete and based on glasshouse plants. Methods We followed sporophyte development in wild populations of Funaria, recording fresh weights of every phenophase. Rates of water loss under laboratory conditions from sporophytes of different ages were recorded, and the ontogeny of the intercellular spaces and the maturational deposition of extra wall materials and waxes were investigated by cryo-SEM. Key results The sporophyte maturation cycle in wild Funaria lasted from December until July (> 200 days), nearly three times that recorded in glasshouses. Fresh weights of green capsules increased until after sporogenesis. Mature brown capsules were highly dehydrated. Prevailing weather conditions or addition of water had no effect on weights. Low rates of water loss, comparable with those from vascular plant leaves, decreased throughout sporophyte maturation under laboratory conditions. These data indicate that Funaria sporophytes mirror homoiohydric vascular plants. Deposition of additional wall materials around the stomatal apertures prevents closure soon after their opening towards the end of post-meiosis capsule expansion. Conclusions With phenophases similar to those of perennial species, Funaria may not be as much a fugitive species as previously assumed. The very brief window in nascent stomata ontogeny when reversible aperture changes might be possible indicates that the likely principal role of Funaria stomata is facilitation of capsule dehydration and not active regulation of gaseous exchange.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2022-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41378151","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}

Its range extends to the southern part of the Russian Far East, where its species are rather widespread in hemiboreal coniferous forests. However, the species to which Russian specimens should be assigned remains unclear. Methods A morphological survey was conducted, along with a molecular phylogenetic study based on the plastid trnS–trnF and nuclear ITS regions. Of the three lineages identified, two were investigated using species distribution modelling. Key results For two of three revealed lineages, the use of the names Glyphomitrium crispifolium Nog. (previously considered to be a rare Japanese endemiс) and G. humillimum (Mitt.) Card. are suggested, whereas the third one, which combines excurrent costae of stem leaves and subulate acumina of the perichaetial leaves, is described as a new species, G. ambiguum Fedosov. In Russia, G. crispifolium is mostly associated with the cooler and more humid climate of hemiboreal forests, whereas G. ambiguum occurs in drier conditions in broadleaved forests. Although the niches of G. crispifolium and G. ambiguum were assessed as being rather similar, their ranges overlap weakly. Conclusions Our results suggest the presence of three species of Glyphomitrium at the northern limit of its distribution in Asia. Results of niche distribution modelling show that the two species’ distributions depend on different predictors, and thus this tool appeared helpful for integrative taxonomic purposes. By contrast, the results of the niche similarity/divergence test were inconclusive.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2022-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45810280","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}

This study investigated the longevity in natural habitat of the diaspore bank of Physcomitrium eurystomum Sendtn., a moss species that is threatened with extinction in Europe. Methods Undisturbed soil cores of 40 cm depth were collected from Langmere, Norfolk, UK, and were split into investigated sediment layers of 1 cm depth. Dating of sediment layers was done by an analysis of radionuclides, and diaspore germination trials of each layer were carried out in a growth chamber. DNA barcoding was used to help identify plants that germinated. Key results and conclusions Viable diaspores of Physcomitrium eurystomum frequently occurred in sediment layers that were at least 100 years old and continued to occur in much lower layers that were probably several hundred years old. The long-term survival of bryophytes underground can have important implications for conservation decisions.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2022-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48638320","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}

Zheng","doi":"10.1080/03736687.2022.2094136","DOIUrl":"https://doi.org/10.1080/03736687.2022.2094136","url":null,"abstract":"Section Papillatae Bischl. is one of the most taxonomically complicated sections in the family Marchantiaceae, due to its ambiguous interand intra-specific delimitation (Zheng and Shimamura 2022). In East Asia, for many years only two subspecies, Marchantia emarginata subsp. tosana (Steph.) Bischl. and M. papillata subsp. grossibarba (Steph.) Bischl., have been recognised in this section (Bischler 1989; Bischler-Causse 1989; Zheng and Shimamura 2020). Although this treatment has been widely adopted in almost all Asian studies, the delimitation between the two subspecies remains ambiguous due to the overlap in some morphological characters, such as the blackish median band on the dorsal surface of the thallus, appendage of the ventral median scales, number of female receptacle lobes, and angle of the basal sinus of the male receptacle. In 2022, Zheng and Shimamura first noted the presence of these ambiguities in the two subspecies of sect. Papillatae in Japan and therefore partly clarified their delimitation by reducing Marchantia tosana Steph. (≡ M. emarginata subsp. tosana) and M. tosayamensis Steph. (= M. emarginata subsp. tosana) under M. papillata subsp. grossibarba. Marchantia emarginata subsp. cuneiloba (Steph.) T.X.Zheng & M.Shimamura was subsequently proposed to replace the former M. emarginata subsp. tosana. Because of the lack of available ordinary specimens from a wide geographical range, previously synonymised taxa of M. emarginata subsp. tosana were also tentatively transferred to subsp. cuneiloba. To provide a clearer delimitation of the two subspecies of sect. Papillatae in East Asia, and to lay the foundation for a future comprehensive revision of the section, these synonyms need to be reviewed. During the taxonomic revision of the family Marchantiaceae in Asia, it has been possible to study the original material of one little known Chinese species, Marchantia fallax Herz. This species was originally described based on a specimen from Yunnan Province, China (Herzog 1930). Since then, no further information on this species was published until Bischler (1989) synonymised the species under M. emarginata subsp. tosana without providing any comments. Detailed taxonomic notes were provided in a subsequent monograph (Bischler-Causse 1989); however, this synonymy still needs to be reviewed because when this treatment was produced, the morphological concepts of accepted species in sect. Papillatae, such as M. emarginata and M. papillata, were neither well understood nor clearly defined. In this note, a detailed description of Marchantia fallax, illustrations of its important taxonomic features, and taxonomic notes are provided.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2022-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46374122","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}
