Printzen C., Ekman S. & Tønsbeg T. (2003): Phylogeography of Cavernularia hultenii: evidence of slow genetic drift in a widely disjunct lichen, Molecular Ecology, 12: 1473-1486

Population structure and history is poorly known in most lichenized ascomycetes. Many species display large-scale infraspecific disjunctions, which have been explained alternately by range fragmentation in species of high age and widespread long-distance dispersal. Using the lichen Cavernularia hultenii, which is widely disjunct across North America and Europe, Pleistocene and Holocene population history was inferred. The internal transcribed spacer (ITS) and part of the the intergenic spacer (IGS) … EN Read more...

Kanz B., Dürhammer O. & Printzen C. (2005): Lichens and lichenicolous fungi of the Bavarian Forest (Lišejníky a lichenikolní houby německé části Šumavy a Českého lesa), Preslia, 77(4): 355–403

A checklist of lichens and lichenicolous fungi reported from the German part of the Bohemian Forest Range (the Bavarian Forest) is presented together with the literature sources. The area covered by the checklist is region 37 circumscribed by Grummann (1963). The list comprises 867 species currently accepted as occurring within the area. A further 44 species have been reported from the area, but their occurrence is regarded as doubtful. Seventy-seven mostly infraspecific taxa from 19th century literature … EN Read more...

Printzen C. & Lumbsch H.T. (2000): Molecular Evidence for the Diversification of Extant Lichens in the Late Cretaceous and Tertiary, Molecular Phylogenetics and Evolution, 17(3): 379-387

A molecular clock based on ITS sequence data from the lichen genera Biatora and Phyllopsora is calibrated with the help of paleoclimatic data and evidence of forest history. The clock indicates that diversification within Biatora started as early as in the Late Cretaceous and took place during periods of climatic cooling, when new types of forest evolved and spread in the Northern Hemisphere. Arctic–alpine species of the genus appear to be of considerable age, dating back to the Late Eocene–Oligocene … EN Read more...

Carter N.E.A. & Viles H.A. (2003): Experimental investigations into the interactions between moisture, rock surface temperatures and an epilithic lichen cover, Building and Environment, 38: 1225-1234

Abstract: This paper examines the links between moisture, epilithic lichens, rock surface temperatures and weathering. Field and laboratory experiments were conducted in order to investigate the combined effect of surface wetness and Verrucaria nigrescens (an epilithic lichen) on limestone temperature fluctuations. Exposure blocks with and without a lichen cover were subjected to short-term temperature fluctuations and two types of moisture events: artificial showers (8 ml rainfall) and larger storms … EN Read more...
