Nanda S.A., Haq M.-u., Singh S.P., Reshi Z.A., Rawal R.S., Kumar D., Bisht K., Upadhyay S., Upreti D.K. & Pandey A. (2021): Species richness and β-diversity patterns of macrolichens along elevation gradients across the Himalayan Arc, Scientific Reports, 11: 20155 [15 p.]

Understanding the species richness and β-diversity patterns along elevation gradients can aid in formulating effective conservation strategies particularly in areas where local anthropogenic stresses and climate change are quite significant as in the Himalaya. Thus, we studied macrolichen richness and β-diversity along elevational gradients at three sites, namely Kashmir (2200 to 3800 m a.m.s.l), Uttarakhand (2000–3700 m a.m.s.l) and Sikkim (1700 to 4000 m a.m.s.l) which cover much of the Indian … Read more...

Langbehn T., Hofmeister J., Svitok M., Mikoláš M., Matula R., Halda J., Svobodová K., Pouska V., Kameniar O., Kozák D., Bače R., Frankovič M. & Svoboda M. (2021): The impact of natural disturbance dynamics on lichen diversity and composition in primary mountain spruce forests, Journal of Vegetation Science, 32:e13087

Aim: Natural disturbances influence forest structure, successional dynamics and con- sequently, the distribution of species through time and space. We quantified the long- term impacts of natural disturbances on lichen species richness and composition in primary mountain forests, with a particular focus on the occurrence of endangered species. Location: Ten primary mountain spruce forest stands across five mountain chains of the Western Carpathians, a European hotspot of biodiversity. Methods: Living … Read more...

(2021): Handbook of field sampling for multi-taxon biodiversity studies in European forests, Ecological Indicators, 132: 108266 [13 p.]

Highlights: • Forest multi-taxon studies have similar aims but different sampling protocols. • The most sampled taxonomic groups are plants, beetles, lichens, birds, fungi. • Soil, litter and canopy resulted as undersampled forest habitats. • Sampling units and substrates differed widely within and among taxonomic groups. • Sampling methods for stand structure were relatively homogeneous. Forests host most terrestrial biodiversity and their sustainable management is crucial to halt … Read more...

Suija A., Delhoume A., Poumarat S. & Diederich P. (2021): Didymocyrtis microxanthoriae (Phaeosphaeriaceae, Dothideomycetes), a new lichenicolous fungus from France, Bulletin de la Société des naturalistes luxembourgeois, 123: 129–136

The new asexual Didymocyrtis microxanthoriae, lichenicolous on Xanthoria parietina, is described from France. Morphological characters and DNA sequence data (ITS, nuLSU) place the new fungus in the genus Didymocyrtis. Didymocyrtis microxanthoriae is only distantly related to the other known species of the genus inhabiting X. parietina, and is characterized by the particularly small, subspherical to shortly ellipsoid, 1(–2)-guttulate conidia, 3.0–3.7 × 2.6–2.9 μm that distinguish it from … Read more...

Villagra J., Muñoz-Muñoz M., Nuñez P. & Casanova-Katny A. (2021): Estudio preliminar de líquenes del orden Peltigerales presentes en el Parque Ecológico y Cultural Rucamanque, Región de La Araucanía, Chile [Preliminary study of lichens of the order Peltigerales in the Ecological and Cultural Park Rucamanque in the Araucania Region, Chile], Gayana Botanica, 78(1): 104–111

[in Spanish with English abstract: ] The Rucamanque Park houses some of the remnants of the Roble-Raulí-Coigüe mixed forest in CentralSouth Chile. Cortical lichens were monitored in Renoval and in the Original Remnant Forest of Nothofagus obliqua (Mirb.) Oerst. We found differences in specific richness by tree species and between the Renoval (13 species) and the Original Remnant (7 species). The variables that affect the greatest richness are discussed, suggesting that the structure of the … Read more...

Beckett R. Minibayeva F. & Mkhize K. (2021): Shade lichens are characterized by rapid relaxation of non-photochemical quenching on transition to darkness, Lichenologist, 53(5): 409-414

Non-photochemical quenching (NPQ) plays an important role in protecting photosynthetic organisms from photoinhibition by dissipating excess light energy as heat. However, excess NPQ can greatly reduce the quantum yield of photosynthesis at lower light levels. Recently, there has been considerable interest in understanding how plants balance NPQ to ensure optimal productivity in environments in which light levels are rapidly changing. In the present study, chlorophyll fluorescence was used to study … Read more...

Sanders W. & Masumoto H. (2021): Lichen algae: The photosynthetic partners in lichen symbioses, Lichenologist, 53(5): 347-393

A review of algal (including cyanobacterial) symbionts associated with lichen-forming fungi is presented. General aspects of their biology relevant to lichen symbioses are summarized. The genera of algae currently believed to include lichen symbionts are outlined; approximately 50 can be recognized at present. References reporting algal taxa in lichen symbiosis are tabulated, with emphasis on those published since the 1988 review by Tschermak-Woess, and particularly those providing molecular evidence … Read more...

The new genus Australidea Kantvilas, Wedin & M. Svensson is described to accommodate Lecidea canorufescens Kremp., a widespread lichen in temperate Australasia. It is characterized by a crustose thallus with a green photobiont, reddish brown, biatorine apothecia with an internally hyaline, cupulate proper exciple constructed of branched and anastomosing hyphae, mainly simple paraphyses, 8-spored, Porpidia-type asci and simple, hyaline, non-halonate ascospores. A phylogenetic analysis places the new … Read more...

Jeong G.S., Hillman P.F., Kang M.-G., Hwang S., Park J.-E., Nam S.-J., Park D. & Kim H. (2021): Potent and selective inhibitors of human monoamine oxidase A from an Endogenous lichen fungus Diaporthe mahothocarpus, Journal of Fungi, 7(10): 876 [18 p.]

Using 126 endogenous lichen fungus (ELF) extracts, inhibitory activities against monoamine oxidases (MAOs) and cholinesterases (ChEs) were evaluated. Among them, extract ELF29 of the endogenous fungus Diaporthe mahothocarpus of the lichen Cladonia symphycarpia showed the highest inhibitory activity against hMAO-A. Compounds alternariol (AT), 5′-hydroxy-alternariol (HAT), and mycoepoxydiene (MED), isolated from the extract, had potent inhibitory activities against hMAO-A with IC50 values of 0.020, … Read more...

Halıcı M.G. & Kahraman M. (2021): DNA barcoding and morphological observations of three lichenized fungal species from James Ross Island (Antarctic Peninsula), Ukrainian Antarctic Journal, 1: 123–148

Antarctica seems to many people to be a very remote, isolated, and mysterious place at the end of the world, and its name is hardly mentioned in normal life and conversation. However, considering that it plays a key role in the rapidly warming global climate system and its contribution to the continuing sea-level rise, its importance today is increasing day by day and it can be seen that it is of vital importance for humanity. There is increasing interest in the distribution of terrestrial … Read more...
