Abstract High performance thin layer chromatography (HPTLC) is a method that can be used for screening lichen substances. It as simple to use standard TLC, but has many advantages: more sensitive, it possible run samples in shorter period of time, and the amount solvent much smaller. The material needed methods are described detail. Horizontal chromatogram development was used. Since two solvents system B have been substituted, since properties HPTLC plates slightly different, our results...
Ancestral state reconstructions of morphological or ecological traits on molecular phylogenies are becoming increasingly frequent. They rely constancy character change rates over trees, a correlation between neutral genetic and phenotypic change, as well adequate likelihood models (for Bayesian methods) prior distributions. This investigation explored the outcomes variety methods for reconstructing discrete ancestral in ascus apex Lecanorales, group containing majority lichen-forming...
Abstract: We tested whether the conspicuous lichen Lobaria pulmonaria indicates number of tree‐dependent, red‐listed species in a hemiboreal forest southern Sweden. In 18 naturally regenerated, mainly old deciduous plots considered to be high or very conservation value, tree lichens wood beetles was not positively correlated with area stands studied (8–56 ha). The 8 L. had about nine (median) lichens, but 10 without only one such species, highly significant difference. Similarly, variation...
Abstract The Ramalinaceae is the fourth‐largest family of lichenized ascomycetes with 42 genera and 913 species exhibiting considerable morphological variation. Historically, generic boundaries in were primarily based on characters. However, molecular systematic investigations subgroups revealed that current taxonomy at odds evolutionary relationships. Tropical members remain particularly understudied, including large genus Phyllopsora . We have generated collected multilocus sequence data...
Lichens are widely acknowledged to be a key component of high latitude ecosystems. However, the time investment needed for full inventories and lack taxonomic identification resources crustose lichen lichenicolous fungal diversity have hampered efforts fully gauge depth species richness in these Using combination classical field inventory extensive deployment chemical molecular analysis, we assessed lichens associated fungi Glacier Bay National Park, Alaska (USA), mixed landscape coastal...
Abstract 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 of high age widespread long‐distance dispersal. Using the lichen Cavernularia hultenii , widely disjunct across North America Europe, Pleistocene Holocene population was inferred. The internal transcribed spacer (ITS) part intergenic (IGS) region nuclear ribosomal DNA were sequenced...
Abstract We estimated phylogeny in the lichen-forming ascomycete family Pannariaceae . specifically modelled spatial (across-site) heterogeneity nucleotide frequencies, as models not incorporating this were found to be inadequate for our data. Model adequacy was measured here ability of model reconstruct diversity per site original sequence A potential non-orthologue internal transcribed spacer region (ITS) Degelia plumbea observed. propose a revised generic classification , accepting 30...

In popular use of Bayesian phylogenetics, a default branch-length prior is almost universally applied without knowing how different would have affected the outcome. We performed and maximum likelihood (ML) inference phylogeny based on empirical nucleotide sequence data from family lichenized ascomycetes, Psoraceae, morphological delimitation which has been controversial. specifically assessed influence combination model properties Markov chain Monte Carlo tree sample, including node support,...

Abstract Question What are the extent and possible causes of imperfect detection in lichens? Because lichens sessile lack seasonality, they should be easier to survey than animals that can move or plants fungi with seasonal morphology, one could therefore expect relatively high probabilities. Location 826 standardised sampling plots across Switzerland. Methods Using repeated detection/non‐detection data from a national lichen conducted by professional lichenologists, we estimated mean...
Recent surveys of the inland rain forests British Columbia and adjacent regions have brought to light an unexpectedly rich epiphytic lichen flora, including several species apparently new science. In first a series papers, we describe eight discovered during these as new: Absconditella amabilis T. Sprib. (Ostropales), Bacidina contecta S. Ekman & Sprib., Biatora aureolepra Tønsberg, ligni-mollis Printzen (all Lecanorales), Collema coniophilum Goward (Peltigerales), Pertusaria diluta C....
