While many reports on extracellular ice formation do exist for vascular plants, not much is known on ice formation for liverworts. In this study, ice formation was studied for two liverwort species occurring in climate zones with winter freezing, Conocephalum salebrosum and Marchanthia polymorpha L. subsp. ruderalis, together with taxon-specific ice nucleating temperature and seasonal concentration of ice nucleating agents. Samples were collected in late autumn from various sites in south west Germany. Afterwards the collected liverwort specimen were cultivated and acclimated in pots in the inner courtyard of the State Museum of Natural History Stuttgart, Germany. Ice formation was observed in the environmental scanning electron microscope (ESEM) within the air chambers of both species, with ice crystals growing out of the air chamber pores, as well as random ice crystal formation on various sites on the ventral side for both taxa. The growing ice sheets led to dehydration particularly of the parenchymatous cells. For both taxa, the observations support the relevance of extracellular ice formation for surviving freezing conditions but the experiments also indicate a better adaptation of C. salebrosum to frost.","PeriodicalId":18037,"journal":{"name":"Lindbergia","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87636924","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}

Studies have demonstrated knotweed allelopathy to the germination and growth of many tracheophytes, but we have found no studies of knotweed toxicity to bryophytes. Therefore, the aim of this study was to determine if knotweed extracts affected the growth of the gametophytes of two mosses: Atrichum angustatum and Thuidium delicatulum. Both moss species were exposed to aqueous rhizome extracts of knotweed in concentrations of 0 (control), 10, 25, 50 and 75% for a total of nine days in the laboratory. All non-zero concentrations resulted in significant losses of green biomass, with the greatest losses occurring at the highest concentrations. Samples exposed to the three highest concentrations lost 80% of green mass after nine days. These results help explain the scarcity of moss growth on or near live knotweed crowns.","PeriodicalId":18037,"journal":{"name":"Lindbergia","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90547755","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}

Sphagnum majus has a very specific niche and is nearly restricted to lithalsas, which are threatened ecological environments in the context of global climatic warming. In Wallonia, male plants of Sphagnum majus subsp. norvegicum are more common than in northern Europe.

A total of 876 individuals (one cushion = one individual) were recorded amongst lava scree on three sucs (volcanic summits), of which 99.6% occur on a single summit. The detailed population counts provide an accurate base-line for future monitoring. Male plants are very rare and the sex-ratio is strongly biased towards females. Sporophytes are also very rare. Coscinodon horridus is a mountain species, strongly linked to harsh environments, mostly on steep exposed slopes of south–east aspect yet is predominately associated with sheltered niches that are protected from direct precipitation and insolation. Sheltered individuals tend to be vegetatively more robust than those growing in more exposed situations. The unique hairpoint anatomy of C. horridus, complex water relations and competitive interactions may explain the narrow niche that this species occupies. Due to the very small area of occupation in France and the low number of individuals, Coscinodon horridus is considered to be threatened in France and is classified as Endangered.","PeriodicalId":18037,"journal":{"name":"Lindbergia","volume":"86 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81267335","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}
