The partitioning of diversity into hierarchical scale-related components is an interesting approach to quantitatively defining the overall net biodiversity from hierarchically scaled studies and is a useful method in studies of conservation biology and restoration. This paper deals with the additive partitioning of the overall diversity and the partitioning of beta-diversity of epiphytic bryophytes along an elevational gradient in Madagascar. The aim is to describe the variation in species composition between sites and to elucidate why different species occur in different communities in the Marojejy National Park (250–2050 m). We looked at the contribution of α and β diversity to total diversity were calculated from four hierarchical scales: microhabitat (50 cm2), quadrat (4 m2), plot (100 m2) and elevation (every 200 m). Furthermore, we documented how the two components of beta-diversity (turnover and nestedness) are influenced by variation in elevation. Our result suggests that more variation in species richness was found within the elevational scales, than within microplot scales, confirming that beta diversity at the largest sampling scale is the largest contributor to the total diversity. It indicates that bryophyte species among sample within each level are a subsample of the same species pool. This study shows evidence that the beta-diversity of epiphytic bryophyte assemblages is dominated by high spatial turnover due to recruitment of new species along the Marojejy transect, a clear pattern for mountains.","PeriodicalId":93270,"journal":{"name":"Bryophyte diversity and evolution","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42752507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With 233 currently accepted species, the genus has one of the most difficult taxonomies among pleurocarpous mosses. Delimitation of Ectropothecium has been challenging because of morphological convergence between closely related genera within the Hypnaceae, namely Hypnum , Isopterygium , Taxiphyllum , and Vesicularia . Redefining the generic limits is based on reassessment of seven critically important morphological features, i.e., branching pattern, pseudoparaphyllium type, leaf shape, laminal cell surface, alar cell formation, capsule size, and exothecial cell walls. Microscopic images of morphological and anatomical important features are used to show generic characteristics. The five closely related genera are morphologically distinct, but oftentimes difficult to separate apart without considering several features at the same time. The generic delineation of Ectropothecium is provided. Neoptychophyllum (Hypnaceae), a new name is proposed for the genus Ptychophyllum , an illegitimate homonym and a previous generic synonym of Ectropothecium .","PeriodicalId":93270,"journal":{"name":"Bryophyte diversity and evolution","volume":"41 1","pages":"17-34"},"PeriodicalIF":0.0,"publicationDate":"2019-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44375191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although several of these species show high morphological resemblance there are strong indications that the genus is highly paraphyletic, which may be masked by convergent morphological evolution. Using molecular information, we analyse whether the morphological similarity of gametophytes of the European Hypnum taxa is explained by common ancestry or convergence. We provide a phylogenetic reconstruction of the relationships of the currently recognized European Hypnum taxa in a broad pleurocarpous moss context (192 taxa) using the nuclear ITS1-5.8S-ITS2, the plastid rps4 gene and trnL-F, and the mitochondrial nad5 intron. Bayesian tree topologies show that the genus is polyphyletic, and we retain only the Hypnum cupressiforme complex within Hypnum. The genus originally represented half of the moss species diversity, as it accommodated basically all pleurocarpous mosses; here we retain only seven species and one variety. The remainder of the species where resolved either within the three families Amblystegiaceae, Entodontaceae, and Pylaisiaceae, or in an independent clade that we describe as the new family Stereodontaceae. The Stereodontaceae includes five European species, all in the genus Stereodon, where they were already placed in the 18th century. In addition, we describe the four new genera Aquilonium, Insomniella, Jochenia, and Lignocariosa, and make new combinations for several Hypnum species.","PeriodicalId":93270,"journal":{"name":"Bryophyte diversity and evolution","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.11646/BDE.40.2.3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47736962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Occurring nearly half a billion years ago, the transmigration of green organisms to land changed the landscape and provided the food source for terrestrial life to invade a vast uninhabited space, adapt and radiate. Although bryophytes (mosses, liverworts and hornworts) are often regarded as the earliest terrestrial organisms, the order of their divergence remains contentious even as molecular analyses become more conclusive with expanded taxon sampling, massive genetic data and more sophisticated methods of analysis (Cox et al. 2018; Morris et al. 2018). Indeed, virtually every combination of relationships among bryophytes has been proposed based on molecules (Qiu et al. 2006; Wickett et al. 2014; Cox et al. 2018). Fortunately, in 2018 it appears that we are approaching a consensus based on molecules, and that is that although bryophytes may or may not be monophyletic, mosses plus liverworts form a natural group (Puttick et al. 2018). In this essay, we point out that this inference is neither new nor surprising as it has been the fundamental conclusion of morphological analyses for over 25 years starting with an exhaustive cladistic analysis of characters associated with motile cell development in green plants (Garbary et al. 1993).","PeriodicalId":93270,"journal":{"name":"Bryophyte diversity and evolution","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44574420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
