The aim of this study was to investigate floristic and ecological attributes of the bryophyte flora of two major islands of the archipelago, Caviana and Mexiana, as a contribution to environmental conservation. In total, 572 samples were studied. The bryoflora of Caviana was represented by 89 species (39 mosses, 50 liverworts) and Mexiana by 50 species (28 mosses, 22 liverworts). Together, the two islands harbored 100 species (46 mosses and 54 liverworts). No statistical similarity was observed in the species composition between the two islands and 50 species were exclusive to Caviana while 11 species were only found on Mexiana. The latter island harbored a greater richness of mosses while liverworts were more diverse on Caviana. Epiphyllous bryophytes were exclusively found on Caviana. The floristic differences between the two islands are explained by differences in environmental conditions and vegetation cover.

Morphological differences between non and sex-expressing plants and the frequent occurrence of non-sex-expressing shoots have generated difficulties in the identification of the group. Our main objective was to morphologically compare the gametophytes of two species of Campylopus: Campylopus julaceus A.Jaeger and Campylopus lamellatus Mont. We performed morphometric analyses (based on 21 gametophyte characters), quantified their sexual expressions, and tested the viability of the asexual propagula produced by C. julaceus. Our results indicate that those putative species do not form two mutually exclusive groups. Sexual expression in C. julaceus was significant (84.4%, with 88.2% females and 11.8% males), compared to the low expression of C. lamellatus (5.29%, 55.5% females and 44.5% males). Asexual propagula occurred in both species, but were more frequently expressed in C. julaceus (100% of the samples; C. lamellatus 31%). Those propagula showed 50 to 60% regeneration, forming rhizoids or green protonemata within only two days. Campylopus lamellatus is often encountered sterile, while C. julaceus is apparently only a sexual form. Additionally, as the sexual success of the species can be restricted by the spatial separation of the sexes, asexual propagula should be useful for population maintenance. Finally, we highlight the importance of studies focusing on DNA analyses at the population level and involving specimens collected globally to better understand the delimitation of sympatric species of Campylopus.","PeriodicalId":50612,"journal":{"name":"Cryptogamie Bryologie","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72881377","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}

P. fimbriatus can be distinguished from other Mexican hornwort species by spore ornamentation, antheridial number per chamber, number of layers of spore tissue in the sporophyte and presence of band-like thickenings in cells of gametophyte thallus. Mexican plants of P. fimbriatus presented smaller spores (28-36 µm in diameter, average 34 µm) than those previously reported (32-43 µm in diameter) for this species, which extends the species variation range of this character and might be pointing out geographical variation.","PeriodicalId":50612,"journal":{"name":"Cryptogamie Bryologie","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2020-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91336400","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}
