Frolov I.V., Prokopiev I.A., Yakovchenko L.S., Galanina I.A. & Ezhkin A.K. (2022): Coppinsiella extremiorientalis (Teloschistaceae, lichenized Ascomycota), a new species from the Russian Far East and a new genus to the region - Phytotaxa, 549(2): 219–229

A new epiphytic species of crustose Teloschistaceae, Coppinsiella extremiorientalis, is described from the floodplain forests of the boreal zone of the Russian Far East. It is characterized by its white to whitish grey, thin to disappearing thallus mostly without anthraquinones, dull orange zeorine pruinose apothecia with an anthraquinones composition corresponding to chemosyndrome A. Phylogeny of the genus Coppinsiella, which was previously unknown in the Far East, is discussed, as well … Read more...

Kantvilas G. (2022): The genus Lambiella Hertel (lichenised fungi) in Tasmania: new combinations, new species and a revised key - Phytotaxa, 549(2): 209–218

Two new species of Lambiella Hertel from Tasmania are described and illustrated: L. parvipsephota Kantvilas, which is similar to the widespread L. psephota (Tuck.) Hertel but differs by lacking norstictic acid in the thallus and sedifolia-grey pigment in the apothecia, and by having smaller apothecia and ascospores, 8−13 × 5−7.5 μm; and L. plumbea Kantvilas, characterised by a grey thallus lacking lichen substances, minute apothecia 0.075−0.13 mm wide, and small ascospores 4−8.5 … Read more...

Schmidt A.R., Steuernagel L., Behling H., Seyfullah L.J., Beimforde C., Sadowski E-M., Rikkinen J. & Kaasalainen U. (2022): Fossil evidence of lichen grazing from Palaeogene amber - Review of Palaeobotany and Palynology, 302: 104664 [10 p.]

Lichens are important in many modern terrestrial ecosystems, but their fossil record has been very sparse. This has limited the chances for finding any evidence of their interactions with animals in past ecosystems. Recently, the fossil record of lichens has improved significantly with the discovery of numerous new inclusions from European Palaeogene ambers. Here, we report the first fossil evidence of animal–lichen interactions from one new fossil from Bitterfeld amber of central Germany. … Read more...

Roos R.E., Birkemoe T., Bokhorst S., Wardle D.A. & Asplund J. (2022): The importance of foundation species identity: A field experiment with lichens and their associated micro-arthropod communities - Basic and Applied Ecology, 62: 45–54

Foundation species provide habitat and modify the availability of resources to other species. In nature, multiple foundation species may occur in mixture, but little is known on how their interactions shape the community assembly of associated species. Lichens provide both structural habitat and resources to a variety of associated organisms and thereby serve as foundation species. In this study, we use mat-forming lichens and their associated micro-arthropods as a miniature ecosystem to study … Read more...

Pakeman R.J., O’Brien D., Genney D. & Brooker R.W. (2022): Identifying drivers of change in bryophyte and lichen species occupancy in Scotland - Ecological Indicators, 139: 108889 [11 p.]

The attribution of biodiversity trends to the action of individual drivers is a first step in developing strategies to conserve, enhance and restore that diversity. One approach to that identification is to link information on species trends with information on ecological preferences that relate to the drivers. Long-term and short-term occupancy trends for 326 bryophyte species (1972–2015 and 2005–2015, respectively) and 437 lichen species (1971–2015 and 2005–2015, respectively) for … Read more...

Chowaniec K., Latkowska E. & Rola K. (2022): Does long-term salt stress of environmentally relevant concentrations affect the physiology of inland lichens? – The importance of rainfall to restore thallus vitality - Environmental and Experimental Botany, 200: 104937 [11 p.]

During winter seasons, sodium chloride is the most widely used de-icing agent for road maintenance. The aim was to determine the effect of long-term spraying with salt solutions of environmentally relevant concentrations on the physiology of two epigeic lichens i.e., Peltigera didactyla and Cladonia rei. We also aimed at studying lichen responses to rainfall simulations between salt treatments to verify whether the liquid water supply would improve the physiological condition of both symbiotic … Read more...

Pinna D. (2022): Can we do without biocides to cope with biofilms and lichens on stone heritage? - International Biodeterioration and Biodegradation, 172: 105437 [13 p.]

In the past several years, products and methods alternative to conventional biocides, used in the conservation of cultural heritage objects, have been investigated increasingly to eradicate or prevent the growth of microorganisms and lichens on stone artworks. Although some concerns about conventional biocides are legitimate, the “run” to alternative substances is growing concern as well. This review aims at contributing to the interpretation of recent findings in innovative methods and … Read more...

Kalın Ş.N., Altay A. & Budak H. (2022): Diffractaic acid, a novel TrxR1 inhibitor, induces cytotoxicity, apoptosis, and antimigration in human breast cancer cells - Chemico-Biological Interactions, 361: 109984 [9 p.]

Breast cancer represents one of the most frequently encountered cancer types among women worldwide. Thioredoxin reductase 1 (TrxR1) is a therapeutic target for breast cancer therapy due to its overexpression in tumor cells. The current research aims to determine the anticancer effect of diffractaic acid, a lichen acid, in breast cancer, and research whether the anticancer effect of diffractaic acid occurs through TrxR1 targeting. According to the XTT assay results, diffractaic acid induced … Read more...

(2022): Novel methods to characterise spatial distribution and enantiomeric composition of usnic acids in four Icelandic lichens - Phytochemistry, 200: 113210 [11 p.]

Usnic acid is an antibiotic metabolite produced by a wide variety of lichenized fungal lineages. The enantiomers of usnic acid have been shown to display contrasting bioactivities, and hence it is important to determine their spatial distribution, amounts and enantiomeric ratios in lichens to understand their roles in nature and grasp their pharmaceutical potential. The overall aim of the study was to characterise the spatial distribution of the predominant usnic acid enantiomer in lichens … Read more...
