A phylogenetic analysis based on the nuclear ITS and plastid rps4 regions was performed to investigate relationships between the new species and closely related taxa. Key results and conclusions Based on morphological and molecular data, we describe this new species from Brazil, Hymenostylium chapadense M.J.Cano & J.A.Jiménez. The species is strikingly distinguished by a stem with central strand and hyalodermis, oblong-ligulate to oblong-elliptical leaves that are when dry slightly crisped in the upper part and usually constricted just above the base and recurved on one side in the lower third, with uni- to bistratose margins, obtuse apex, costa wide and ending below the apex or percurrent with ventral and dorsal surface cells of the costa differentiated as an epidermis, and middle laminal cells usually with a simple, coarse, central papilla. Our molecular study placed H. chapadense as sister to H. hildebrandtii (Müll.Hal.) R.H.Zander. Possible confusion with the latter species and other closely related taxa is discussed. A key to the South American species of Hymenostylium is provided.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46585694","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}

Specifically, we have identified 50 fundamental questions that are critical in advancing the discipline. Methods We have adapted a deep-rooted methodology of horizon scanning to identify key research foci. An initial pool of 258 questions was prepared by a multidisciplinary and international working group of 32 bryologists. A series of online surveys completed by a broader community of researchers in bryology, followed by quality-control steps implemented by the working group, were used to create a list of top-priority questions. This final list was restricted to 50 questions with a broad conceptual scope and answerable through realistic research approaches. Key results The top list of 50 fundamental questions was organised into four general topics: Bryophyte Biodiversity and Biogeography; Bryophyte Ecology, Physiology and Reproductive Biology; Bryophyte Conservation and Management; and Bryophyte Evolution and Systematics. These topics included 9, 19, 14 and 8 questions, respectively. Conclusions Although many of the research challenges identified are not newly conceived, our horizon-scanning exercise has established a significant foundation for future bryological research.

Goffinet is a rare epiphytic moss characteristically associated with water-filled holes in trees. We reviewed its range and population and assessed effects of climate change. Methods An inventory of sites from where Codonoblepharon forsteri has been recorded was compiled. Extent of occurrence (EOO) and area of occupancy (AOO) were calculated. Population size was estimated, treating an occupied tree as an ‘individual-equivalent’ of the moss. Climatic conditions of the species’ current distribution were characterised, and an ensemble model of its distribution was generated. The latter was projected onto present and future climatic layers. Key results Codonoblepharon forsteri has been recorded from 19 countries and 205 sites in Europe, North Africa and Southwest Asia. It has been undergoing an overall decline. Most sites have few occupied trees, and a world population of 1000–10,000 individual-equivalents is estimated. Model projections suggest that the species will experience a range increase of +0.36–0.65 by 2050 and +0.35–0.68 by 2070, especially in its northwest range, particularly across France and the UK. Range loss is predicted to be between –0.20 and –0.39 in 2050 and –0.21 and –0.65 in 2070, affecting the driest areas of the current range around the Mediterranean, especially in North Africa. Conclusions Codonoblepharon forsteri has a relatively large EOO but relatively small AOO, probably due to habitat specialism. A major reason for recent declines appears to be widespread abandonment of traditional ‘pollarding’ of trees. The potential climatic range of the species will shift significantly northwards over the next few decades.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48696725","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 was carried out to investigate its population status and ecology in England and Wales, UK. Methods Surveys were undertaken at all previously known sites where the species may currently occur in England and Wales. Geographical coordinates of colonies were recorded with a GPS unit, and counts made of occupied 1 m grid cells. Habitat and community composition were recorded by relevés. Key results Biantheridion undulifolium has been reported from 16 sites in England and Wales. It has become extinct at six (38%), and its continued existence at two others is uncertain. Following 52 h of search effort, 88 occupied 1 m grid cells were found across eight sites. The estimated true total is 196–433 occupied 1 m grid cells. Only three sites support sizeable populations; most sites support < 10 occupied 1 m grid cells. The species is confined to mesotrophic flushes and bogs, mostly occurring on hummocks of Sphagnum capillifolium s.l. that are moderately to heavily compacted by grazing livestock. Occupied hummocks tend to be composed of Sphagnum in good health, with few signs of necrosis. Fertile plants of this dioicous liverwort are rare, and no sporophytes were found. Conclusions Biantheridion undulifolium is a ‘competitive perennial stayer’ with limited dispersal ability, and has undergone a significant decline in England, and probably also in Wales. Adequate grazing pressure appears to be especially important for its survival. Most sites occur outside protected areas.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41903662","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}

Although these rheophilous species are similar morphologically, Olsson et al. (2009) concluded that this was probably the result of convergent evolution, and that each appears to have evolved independently from surrounding populations of T. alopecurum (Hedw.) Gangulee. Thamnobryum cataractarum (Figure 1) is one of 25 moss species that are listed on the world IUCN Red List as Critically Endangered, the highest category of global extinction risk (IUCN 2021). It is known from only a single site: Twistleton Glen, Mid-west Yorkshire (v.-c. 64), UK. Searches for other populations at potential sites within the wider region have been unsuccessful (Hodgetts 2005a). Within the riverine gorge of Twistleton Glen, the moss occupies a narrow niche, limited to rock substrate in areas of cascades and waterfalls. The species has been the subject of a national conservation action plan and in England is considered a species of principal importance for conservation under Section 41 of the Natural Environment and Rural Communities Act 2006. Despite the high degree of conservation concern, since the discovery of Thamnobryum cataractarum in September 1991 (Hodgetts and Blockeel 1992) there has been only a single survey of its population at Twistleton Glen, this having been done in September 2005 (Hodgetts 2005b), plus a brief and partial monitoring visit in May 2010 (Goodison 2010). The aim of the present study was to investigate the current population status and ecology of T. cataractarum. Taxonomy follows Blockeel et al. (2021). Twistleton Glen is a deep and narrow wooded gorge that has been carved by an existing river through interbedded sandstones and siltstones of the Ordovician Ingleton Group, located on the western edge of the Yorkshire Dales National Park in northern England. These rocks are base-deficient, but the river water flowing through the gorge is baseenriched because the rock of the wider catchment is mostly Carboniferous limestone (Garsdale Limestone Formation). The glen is located within the Thornton and Twistleton Glens Site of Special Scientific Interest and forms part of a walking route known as Ingleton Waterfalls Trail, managed as a tourist attraction by a private company. The climate is oceanic, with 187 rain days/year and average air temperatures of 12.7°C during the hottest month (July) and 1.2°C during the coldest month (February) for the period 1961–2002 (Met Office data supplied through the UK Climate Impact Programme).

Methods Material from the new locality was compared morphologically with material from Derbyshire and Cumberland (now combined with Westmorland to form Cumbria) in England and with the adjacent population of Thamnobryum alopecurum (Hedw.)

The sequences obtained were compared with data available in GenBank. Key results and conclusions Morphologically, the material from the Italian population is very close to the English populations, especially the one from Cumberland, but there are minor differences between all three populations. The differences are not considered sufficient to merit the description of a new taxon. Thamnobryum angustifolium is therefore new to Continental Europe.

All trees known to have been occupied by Codonoblepharon forsteri were surveyed and reasons for losses were selected from a predetermined list. A random sample of veteran pollards were surveyed, in addition to all trees within three woodland compartments. Key results Of the 76 trees previously recorded as having been occupied by Codonoblepharon forsteri, 71 were refound; the moss was present on 33 (46%) of them. The main causes of losses of C. forsteri were competitive exclusion and tree death. The species was found on 11 (19%) of the 59 veteran pollards sampled.

It is unusual to encounter male-biased populations of dioicous mosses. We report a case of a non-native (to the USA) dioicous moss, Gemmabryum klinggraeffii, in male-biased populations established through tuber recruitment from the soil propagule bank in an urban park in the context of an invasive plant removal experiment. Methods. The mosses in this study originated from soil samples taken from an urban park in the Midwestern USA. Within the park, soils were taken from plots that underwent invasive species removal and control plots that did not undergo species removal. Mosses emerging from the soil samples were propagated and grown for 1 year, after which the density of Gemmabryum klinggraeffii plants per pot and the mean numbers of tubers and gametophores were computed. Key results. Gemmabryum klinggraeffii was more likely to occur in soil from control sites where invasive species had not been removed. The number of tubers per stem was dependent on the abundance of G. klinggraeffii in the pot, such that pots with more G. klinggraeffii produced more tubers per stem on average. Plants with and without gametophores produced similar numbers of tubers, and the only sex organs detected in the populations were antheridia. Conclusions. Gemmabryum klinggraeffii depends on rhizoidal tubers that persist in soil propagule banks and are important to local population persistence in the urban park studied. Potentially other populations in North America are also male, single-sex populations that deserve further attention.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2021-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43053738","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}
