Barták M., Hájek J., Halıcı M.G., Bednaříková M., Casanova-Katny A., Váczi P., Puhovkin A., Mishra K.B. & Giordano D. (2023): Resistance of primary photosynthesis to photoinhibition in Antarctic lichen Xanthoria elegans: Photoprotective mechanisms activated during a short period of high light stress - Plants, 12(12): 2259 [15 p.]

The Antarctic lichen, Xanthoria elegans, in its hydrated state has several physiological mechanisms to cope with high light effects on the photosynthetic processes of its photobionts. We aim to investigate the changes in primary photochemical processes of photosystem II in response to a short-term photoinhibitory treatment. Several chlorophyll a fluorescence techniques: (1) slow Kautsky kinetics supplemented with quenching mechanism analysis; (2) light response curves of photosynthetic electron transport … Read more...

Vega J., Bárcenas-Pérez D., Fuentes-Ríos D., López-Romero J.M., Hrouzek P., Figueroa F.L. & Cheel J. (2023): Isolation of mycosporine-like amino acids from red macroalgae and a marine lichen by high-performance countercurrent chromatography: A strategy to obtain biological UV-filters - Marine Drugs, 21(6): 357 [17 p.]

Marine organisms have gained considerable biotechnological interest in recent years due to their wide variety of bioactive compounds with potential applications. Mycosporine-like amino acids (MAAs) are UV-absorbing secondary metabolites with antioxidant and photoprotective capacity, mainly found in organisms living under stress conditions (e.g., cyanobacteria, red algae, or lichens). In this work, five MAAs were isolated from two red macroalgae (Pyropia columbina and Gelidium corneum) and one marine … Read more...

Jafarova M., Grifoni L., Aherne J. & Loppi S. (2023): Comparison of lichens and mosses as biomonitors of airborne microplastics - Atmosphere, 14(6): 1007 [9 p.]

The atmosphere is an important pathway for microplastic (MP) transport; however, observations are limited, as traditional sampling methods are generally labor-intensive. Biological monitors (biomonitors) have been widely used as a simple alternative to determine the abundance or presence of anthropogenic pollutants. Here, we compared the effectiveness of co-located lichen and moss species as biomonitors of the atmospheric deposition of microplastics. Samples of the epiphytic lichen Evernia prunastri … Read more...

Chowaniec K., Latkowska E. & Skubała K. (2023): Effect of thallus melanisation on the sensitivity of lichens to heat stress - Scientific Reports, 13: 5083 [14 p.]

Extreme climatic phenomena such as heat waves, heavy rainfall and prolonged droughts are one of the main problems associated with ongoing climate change. The global increase in extreme rainfalls associated with summer heatwaves are projected to increase in amplitude and frequency in the near future. However, the consequences of such extreme events on lichens are largely unknown. The aim was to determine the efect of heat stress on the physiology of lichen Cetraria aculeata in a metabolically … Read more...

Garrido-Benavent I., de los Ríos A., Núñez-Zapata J., Ortiz-Álvarez R., Schultz M. & Pérez-Ortega S. (2023): Ocean crossers: A tale of disjunctions and speciation in the dwarf-fruticose Lichina (lichenized Ascomycota) - Molecular Phylogenetics and Evolution, 185: 107829 [13 p.]

Lichens thrive in rocky coastal areas in temperate and cold regions of both hemispheres. Species of the genus Lichina, which form characteristic black fruiting thalli associated with cyanobacteria, often create distinguishable bands in the intertidal and supralittoral zones. The present study uses a comprehensive specimen dataset and four gene loci to (1) delineate and discuss species boundaries in this genus, (2) assess evolutionary relationships among species, and (3) infer the most likely causes … Read more...

Pykälä J. & Myllys L. (2023): Additions to the lichen flora of Finland. XI - Graphis Scripta, 35(5): 66–74

Lichen flora of broad-leaved forests and serpentine rock outcrops of Finland was studied during the year 2021. Seven lichen species are reported here as being new to Finland: Caloplaca grimmiae, Catillaria scotinodes, Lecanographa amylacea, Lecidella laureri, Rhizocarpon infernulum, Rinodina lecanorina and Tetramelas phaeophysciae. ITS sequences are provided for the species. Read more...
