Intercontinental disjunct distributions of many bryophytes continue to raise questions about their nature and origin. While mounting evidence points to long-distance dispersal as a mechanism to explain broad distribution ranges, there is a need to clarify whether the disjunct populations belong to the same species connected by gene flow or actually harbor hidden genetic variation indicating speciation due to geographic isolation. During recent fieldwork, new populations of a moss morphologically matching Orthotrichum consobrinum were discovered in eastern North America. This moss had until this point been considered to be restricted to Eurasia. To shed light on the identity of these new populations and their nature as a species with intercontinental range versus cryptic speciation, we compared morphological characters with molecular sequence divergence over the global range of O. consobrinum and the putative American populations. Our results identify the North American specimens as belonging to O. consobrinum, forming a monophyletic group with specimens from eastern and western Asia. This study therefore provides an addition to the North American flora, alongside a description and images of distinguishing morphological features to facilitate the differentiation from the closely related Orthotrichum stellatum. The known distribution of O. consobrinum is now conceived as disjunct pan-Holarctic, adding new evidence to the long-distance dispersal capacities of bryophytes.","PeriodicalId":55319,"journal":{"name":"Bryologist","volume":"124 1","pages":"403 - 413"},"PeriodicalIF":0.9,"publicationDate":"2021-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47084630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study of the liverwort and hornwort flora of Vietnam has received additional interest in recent years as many new records have been revealed. This raises the question of the number of new records that may possibly be found and where they should be located. Data on new liverwort occurrences within the last 55 years were summarized to identify whether the discovery ‘plateau’ has been reached. The bioclimates of the localities of the newest records were examined using canonical correspondence analysis (CCA) to determine whether there was any regularity in the distribution of the new records. Progress in liverwort flora knowledge has not reached a plateau; moreover, within recent years, the number of recorded species has grown quickly. The new records are located in mountainous areas, and climatic characteristics of localities are different from those of the dominant low elevations in the study area. At the current stage 573 taxa (568 species plus 5 varieties) are known in Vietnam. They belong to 105 genera of 46 families. Vietnam has recently become a flagship country in the study of liverwort diversity in Indochina, and the regularities found in the country may be applied to other countries in this macroregion. Higher numbers of recorded species than are now known may be found in all Indochina countries. Mountainous land areas possess the potential ability to harbor a high number of new records.","PeriodicalId":55319,"journal":{"name":"Bryologist","volume":"124 1","pages":"391 - 402"},"PeriodicalIF":0.9,"publicationDate":"2021-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46955178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Long considered one of the best examples of a moss endemic to the Blue Ridge Escarpment of the Southern Appalachian Mountains, “Mnium carolinianum” has been reduced to synonymy with the widespread pantropical Plagiomnium rhynchophorum. It therefore joins a number of other bryophytes and ferns that represent tropical species disjunct to the moderated microenvironments provided by the deep gorges of these high-rainfall mountains. Our evidence from starch gel electrophoresis of isozymes and sequencing of both chloroplast (rps4 and rpL16) and nuclear (ITS2) DNA supports this taxonomic decision originally proposed by Timo Koponen but largely ignored in recent checklists and floras. A similar situation prevails in Hawaii, where plants previously referred to P. rostratum also proved to be P. rhynchophorum. Both of these species are allopolyploids, expressing fixed heterozygosity at diagnostic loci. Although more extensive sampling of populations and additional genetic markers are desirable, it is clear that P. rhynchophorum combines the genomes of P. maximoviczii and P. integrum, whereas P. rostratum combines the genomes of P. vesicatum and P. integrum. This conclusion is congruent with morphological evidence, which shows the allopolyploids are intermediate or combine diagnostic characters of the progenitor haploids.","PeriodicalId":55319,"journal":{"name":"Bryologist","volume":"124 1","pages":"343 - 351"},"PeriodicalIF":0.9,"publicationDate":"2021-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44335396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Species distribution models (SDMs) rely on the concept of niche theory that suggests that individual species live within definable ranges of environmental conditions. Comparisons of SDMs between species can help further the understanding of competitive exclusion and niche differentiation. SDMs were created for Erioderma pedicellatum, E. mollissimum, Pectenia plumbea and Pannaria lurida, four sympatric species that occur in Nova Scotia, Canada. Logistic regression was used to create SDMs using nine environmental explanatory variables and presence of the modeled species as the response variable. There was significant overlap in environmental space between species, but each species tended to occupy a unique combination of environmental attributes. The Erioderma pedicellatum model from this study suggests this species occurs in cooler wet climate at mid-elevations in older closed canopy coniferous forest. Results from this study indicate Erioderma mollissimum occurs in old to mature deciduous forests at low to mid-elevation in warm, moderately wet climates. Pectenia plumbea tended to be found at low to mid-elevations in areas with moderately cool temperature with mid to high mean annual precipitation. Pannaria lurida tended to occupy mature to old forests occurring in areas with mid-range mean annual precipitation at higher elevations. Since this study examined a relatively small number of environmental variables, further study at different scales and with more extensive datasets would likely reveal further insights into competitive exclusion among these four cyanolichens.","PeriodicalId":55319,"journal":{"name":"Bryologist","volume":"124 1","pages":"323 - 334"},"PeriodicalIF":0.9,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47869567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
