Brid. is rare in Europe and threatened with extinction. In this study, its status and ecology in Britain were investigated. Methods Surveys were carried out at all sites from which Philonotis marchica has been reported in Britain since 1859, together with further locations nearby. Geographical coordinates of colonies were recorded with a GPS unit and used to derive counts of occupied Ordnance Survey grid cells at resolutions of 1, 10 and 100 m. The habitat and community composition of relevés were recorded. Key results Philonotis marchica was found at two closely located sites on the Isle of Wight, occupying a total of 32 1 m grid cells. It was not refound at the only other previously known location in Britain, which is in Yorkshire. The species was found exclusively within perennial seepages (pH 7.4–7.6) over steep sandstone rock, where vascular plants are sparse and the most frequent bryophyte associates include Didymodon tophaceus (Brid.) Lisa, Pellia endiviifolia (Dicks.) Dumort. and Pohlia melanodon (Brid.) A.J.Shaw. Sporophytes of P. marchica in Britain have never been reported and populations seem to comprise only females. Axillary bulbils, produced abundantly, are probably of key importance for local dispersal and population maintenance. Conclusions Philonotis marchica appears to have become extinct in Yorkshire and has undergone a historical decline at Shanklin Chine, Isle of Wight. The population at Lake Cliffs, Isle of Wight, appears to be secure and deserves statutory protection given its key importance for the future survival of P. marchica in Britain.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2021-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47302529","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}

Earlier studies conflicted in suggesting that T. austriaca Hedw. either displays limited phylogeographical structure or includes large molecular variation with potential for geographical structure. Methods Relationships within Timmia were inferred from variation in the nuclear 26S and plastid atpB–rbcL and trnL–trnF. New sequences were generated for 64 specimens of T. austriaca. For other Timmia species, sequences came primarily from earlier studies or GenBank. Key results Timmia includes two main, well-supported molecular lineages. Within T. austriaca, four arctic or subarctic specimens resolved in a small-lineage sister to all other specimens. Conclusions Recognition of two sections is suggested: Timmia Hedw. sect. Timmia (syn. sect. Timmiaurea Brassard; syn. sect. Sphaerocarpa Y.Jia & Yang Liu bis) and sect. Norvegica Brassard. Timmia fossils, including T. austriaca, were deposited at least 3 Myr BP in northernmost North America under a milder climate than presently in that area. It is theorised that plants of the small T. austriaca lineage evolved adaptations to survive only under cold conditions, when the Arctic was gradually cooling. Timmia austriaca disperses easily, and because the numerous temperate region samples studied included no representatives of the northern lineage, the restricted distribution of this lineage is suggested to have resulted from adaptation to cold environments. In situ survival of T. austriaca in Fennoscandia during the Late Glacial Maximum, as previously theorised, is deemed unlikely due to glacial erosion and submergence of large areas as a result of isostatic depression.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2021-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41805145","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 paper reports the results of further fieldwork, both in Atewa and elsewhere, in 2017, and makes some necessary additions and amendments to previously published data. Methods Bryophyte fieldwork was carried out in key forest sites in southern Ghana during November 2017, and was followed by targeted herbarium studies.

Conclusions This study shows that even lowland areas of remaining forest in Ghana are bryologically interesting and that bryophytes are an important but still under-recorded part of Ghana’s biodiversity.

Owing to its small size and unusual life cycle, its developmental stage is key for its detection in the field, so it is surprising that intensive field research on its phenology has not previously been carried out. Methods During a systematic study from 2014 to 2020, data from extensive (space-for-time) and intensive surveys were collected on the development of Buxbaumia viridis sporophytes in Hungary. Damage to sporophytes and sporophyte survival rate were also examined. Key results Twelve developmental stages were distinguished and characterised in this study. Juvenile sporophytes started to grow in autumn, and about half of the sporophytes died before their maturation in summer. Asexual propagules (gemmae) were produced all year round. Conclusions Precise description of the developmental characteristics helps distinguish Buxbaumia viridis from B. aphylla, even at juvenile stages in autumn; however, early spring was found to be the best period for field surveys. The observed mortality rate is probably a species-specific constant, so (on its own) may not pose a threat to the survival of populations. Large numbers of gemmae probably increase the likelihood of local survival.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2021-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03736687.2021.1916169","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42791864","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}

Relationships between specimens were explored with maximum likelihood and Bayesian inference analysis. A morphological study comparing the material to F. sublimbatus was also made. Key results and conclusions Molecular data showed high support for the recognition of a new species that also presents some morphological differences from Fissidens sublimbatus. Consequently, F. eremicus J.Guerra & J.A.Jiménez has been here described as a new species that can be considered as pseudocryptic and is readily confused with F. sublimbatus.

The moss Micromitrium tenerum is rare in Europe and threatened with extinction. The aim of this study was to investigate its population status and ecology in England. Methods. Surveys were undertaken at most of the sites from where Micromitrium tenerum has been reported in England. Geographical coordinates of colonies were recorded with a GPS unit and used to derive counts of occupied Ordnance Survey grid cells at resolutions of 1, 10 and 100 m. Habitat and community composition were recorded by relevés. Key results. Micromitrium tenerum was found at three locations, one in North Devon and two adjacent sites in East Sussex, with a total of 25 occupied 1 m grid cells. It is likely to survive at a fourth site in West Sussex. Powdermill Reservoir (East Sussex) supported the majority (84%) of the population censused. The species has been lost from at least 11 sites, all in southeast England. Most current and historical locations of the moss were within the drawdown zone of seasonally fluctuating freshwater bodies, a notable exception being on muddy ground along tracks in an adjacent woodland. Vegetation comprised an open community of vascular plants and bryophytes, which most typically included Physcomitrium patens and Pseudephemerum nitidum. Soils were silty clays and strongly acidic (pH 4.1–5.1). Conclusions. Micromitrium tenerum has undergone a historic decline in England, due to a mixture of wetland loss, involving drainage and built development, and habitat transformation driven by change in wetland use. Presently, competitive exclusion by the non-native invasive New Zealand pigmyweed, Crassula helmsii, is the biggest threat to its future survival.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2021-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03736687.2021.1910436","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44944979","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}
