At both sites the number and developmental stages of sporophytes were frequently recorded and sporophyte maturity indices and survival rates were determined. The timing of sporophyte development was similar between the two generations but differed between the growth sites with earlier sporophyte development at Nunspeet. The growth sites are located close to each other and share the same climate and soil characteristics. The growth site at Nunspeet, however, is shaded and consequently a higher soil moisture early in the season might explain early sporophyte development. Sporophyte survival was extremely low, especially at Nunspeet (0.4% and 0.9% in 2014–2015 and 2015–2016 respectively) due to fungi and, possibly, slugs and birds.","PeriodicalId":18037,"journal":{"name":"Lindbergia","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88245750","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}

The site where the species occur is increasingly impacted by ecotourism and forest ecology teaching. Limitation of teaching at the site, reduction of the number of trails and stricter conservation is recommended in order to protect the fragile local epiphyllous community.","PeriodicalId":18037,"journal":{"name":"Lindbergia","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81574466","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}

In contrast, P. handelii is a filiform plant with distant, ovate-acuminate leaves. In sequence identity the three terminals have a similar level of variation, suggesting that the geographic disjunction between the two populations of P. handelii is quite old. Morphologically and genetically the clade is a well defined lineage (Ortholimnobium) that is transitional between Plagiothecium s.str. and Struckia. The new combinations O. paleaceum and O. handelii are made.

Several allelopathically active chemicals in bryophytes have been discovered since the latter half of the 20th century and laboratory studies have showed their inhibiting impact on germination, growth and establishment of surrounding plants. However, other studies failed to demonstrate these effects. In the field, other properties of bryophytes might have stronger impacts, such as mechanical obstruction or alterations in temperature. In laboratory studies, water might not be an adequate extractant for active substances, since all of the chemicals claimed to be allelopathic are lipophilic with potentially longer retention times of the active substances in the soil when compared to water-soluble substances.","PeriodicalId":18037,"journal":{"name":"Lindbergia","volume":"28 6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75788716","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}

This species differs from members of the other two O. wahlenbergii lineages by its more longly and narrowly acuminate leaves, projecting cell walls in the upper leaf margins, and the excurrent costa being rough from projecting cells or cell walls. Contrary to members of the other two O. wahlenbergii lineages, O. demetrii seems to prefer base-rich habitats. Outside Scandinavia, it is at present known from Labrador in Canada. Oncophorus compactus (Bruch & Schimp.)

Diverse and widespread hybridization has been widely documented in the genus, but little is known about what factors underlie this phenomenon. We hypothesize that these factors include phylogenetic distance and variation in life-history traits of parental species. We summarize current knowledge about the occurrence of hybridization in peatmosses and explore how it is associated with phylogenetic distance and life-history trait variation of parental species. Possibly as much as one out of five (or more) peatmoss species hybridize, mostly producing allopolyploid hybrids. Parents of admixed haploids are more closely related to each other than parents of allopolyploids. Hybridization seems to be most frequent in 1) monoicous and polyoicous species exhibiting 2) relatively high sporulation frequency, 3) producing relatively small spores, as well as 4) growing in poor habitats. Surprisingly, neither phylogenetic proximity nor life-history trait variation explain patterns of hybridization in peatmosses, and other likely explanations for patterns observed are discussed.","PeriodicalId":18037,"journal":{"name":"Lindbergia","volume":"1 1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78656305","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}

The growth rate depends on the quality of the micro-habitat. Clonal growth and dispersal of plant fragments are important parameters to understand local distribution of bryophytes lacking spore and gemmae production. Species of the mixed northern hepatic mat mainly rely on plant fragments and vegetative growth to disperse and maintain local populations. Understanding a species' means for population maintenance and dispersal potential is important for a successful management. This study aims to investigate the micro-scale climatic requirements and growth rate of the mixed northern hepatic mat species Scapania nimbosa through measuring its growth in situ in Norway, and through comparison of micro-climate between presence localities and seemingly suitable absence localities. The results show that S. nimbosa grows approximately 4.38 ± 2.78 mm during one growing season. No difference in micro-climate was found between the presence and absence localities, suggesting that S. nimbosa is limited by dispersal, not by suitable habitats. The availability of suitable habitat, and the ability to identify these, opens up the possibility to expand its range through transplantation of plant fragments.","PeriodicalId":18037,"journal":{"name":"Lindbergia","volume":"9 1","pages":"1 - 10"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79914454","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}
