Vo Q.V. , Hieu L.T., Hang H.T.C., Diep V.H.N., Hoa N.T., Huynh U.T.D., Trung N.Q. & Mechler A. (2024): Is lecanoric acid a good antioxidant? - Journal of Molecular Liquids, 408: 125336 [6 p.]

Lecanoric acid (LA), an abundant chemical found in lichens, has demonstrated a wide range of biological activities, including anti-cancer cytotoxic, antibiotic, antimycobacterial, antiviral, and anti-hepatocarcinoma properties. The antioxidant capacity of this molecule, while inferred from certain experimental findings, is doubtful based on structural characteristics and therefore remains to be established. DFT calculations are used in this work to conduct a comprehensive evaluation of the mechanism … Read more...

Mendili M., Sellami Z., Somai R. & Khadhri A. (2024): Assessing Tunisia’s urban air quality using combined lichens and Sentinel-5 satellite integration - Environmental Monitoring and Assessment, 196: 545 [19 p.]

In Tunisia, urban air pollution is becoming a bigger problem. This study used a combined strategy of biomonitoring with lichens and satellite mapping with Sentinel-5 satellite data processed in Google Earth Engine (GEE) to assess the air quality over metropolitan Tunis. Lichen diversity was surveyed across the green spaces of the Faculty of Science of Tunisia sites, revealing 15 species with a predominance of pollution-tolerant genera. The Index of Atmospheric Purity (IAP) calculated from the lichen … Read more...

Gačnik J., Živković I., Kotnik J., Božič D., Tassone A., Naccarato A., Pirrone N., Sprovieri F., Steffen A. & Horvat M. (2024): Comparison of active measurements, lichen biomonitoring, and passive sampling for atmospheric mercury monitoring - Environmental Science and Pollution Research, 31: 35800–35810

The number of atmospheric mercury (Hg) monitoring stations is growing globally. However, there are still many regions and locations where Hg monitoring is limited or non-existent. Expansion of the atmospheric Hg monitoring network could be facilitated by the use of cost-effective monitoring methods. As such, biomonitoring and passive monitoring offer a unique alternative to well-established monitoring by active measurements, since they do not require a power supply and require minimal workload to … Read more...

Kachalkin A., Tomashevskaya M., Pankratov T. & Yurkov A. (2024): Endothallic yeasts in the terricolous lichens Cladonia - Mycological Progress, 23: 29 [31 p.]

Lichens are multi-component microbial communities where yeasts are common. This work was designed to address the taxonomic diversity and distribution of cultivated endothallic yeasts in terricolous lichens of the genus Cladonia. Lichens Cladonia stellaris, C. rangiferina, C. cornuta, and C. pleurota from arctic, subarctic, and continental boreal climates in Russia in a range of biotopes were studied. In total, 40 yeast species were isolated. It revealed a broad taxonomic range of endothallic … Read more...

Bogale A.T., Braun M., Bernhardt J., Zühlke D., Schiefelbein U., Bog M., Scheidegger C., Zengerer V., Becher D., Grube M., Riedel K. & Bengtsson M.M. (2024): The microbiome of the lichen Lobaria pulmonaria varies according to climate on a subcontinental scale - Environmental Microbiology Reports, 16: e13289 [14 p.]

The Lobaria pulmonaria holobiont comprises algal, fungal, cyanobacterial and bacterial components. We investigated L. pulmonaria's bacterial microbiome in the adaptation of this ecologically sensitive lichen species to diverse climatic conditions. Our central hypothesis posited that microbiome composition and functionality aligns with subcontinental-scale (a stretch of ~1100 km) climatic parameters related to temperature and precipitation. We also tested the impact of short-term weather dynamics, … Read more...

Johnston P.R. & Park D. (2024): Historical cultures provide insights into the taxonomy of Stictis sensu lato - Fungal Systematics and Evolution, 14: 153–170

Species morphologically typical of the genus Stictis are phylogenetically diverse, spread throughout Stictidaceae. Phylogenetic studies based on DNA sequences have revealed the polyphyletic nature of the morphologically defined genus, the type species Stictis radiata forming a clade phylogenetically distinct from all other sequenced species that had been placed in the genus. Some of the phylogenetic clades containing Stictis sensu lato species can be distinguished on the basis of their asexual … Read more...

Timdal E., Möller E.J. & Bendiksby M. (2024): Rhizocarpon vulgare, a new species in the R. badioatrum species complex - Graphis Scripta, 36(4): 89–105

Herein, we revise the Rhizocarpon badioatrum species complex in the Nordic countries using molecular phylogenetics combined with morphological/anatomical and chemical data. Bayesian and Maximum Likelihood phylogenetic analyses of the nuclear ribosomal internal transcribed spacer (ITS, the fungal DNA barcode) reveals four strongly supported clades within the R. badioatrum species complex. Based on our assessment of the multiple sources of data included, we recognize R. badioatrum var. badioatrum … Read more...

Moreno-Palacios M., Torres-Benítez A., Soto-Medina E., Sánchez M., Divakar P.K., Pereira I. & Gómez-Serranillos M.P. (2024): Corticolous lichen communities and their bioindication potential in an urban and peri-urban ecosystem in the central region of Colombia - Land, 13(7): 932 [16 p.]

The richness, composition, abundance, and correlation with the atmospheric oxide concentrations of the community of corticolous lichens in the urban and peri-urban areas of the city of Ibagué (Colombia) were evaluated, selecting 25 individuals of the four most abundant phorophyte species. Twenty-nine lichen taxa grouped in 13 families and 17 genera were recorded, with a higher lichen coverage and taxa richness in the urban area. A non-metric multidimensional scaling (NMDS) analysis showed the conformation … Read more...

Masson D., Magain N. & Sérusiaux E. (2024): Small island but great diversity: thirty six species of Parmotrema (Parmeliaceae, lichenized Ascomycota), including sixteen new species, on Réunion (Mascarenes), with additional data from the Western Indian Ocean - Phytotaxa, 657(1): 1–138

This work is part of our taxonomical and phylogenetic studies on the lichen flora of Réunion (Mascarene Archipelago, Indian Ocean). Thirty-six species belonging to the conspicuous genus Parmotrema are recognized on the island, sixteen being new to science: P. aurantioreagens, P. brachyblepharum, P. crossotum, P. eleonomum, P. intonsum (also found in Madagascar), P. mezierii, P. mascarenense (also found in Mauritius), P. mirum, P. nemorum, P. nephophilum, P. occultum, P. orarium, P. paramascarenense … Read more...

Daminova A.G., Leksin I.Y., Khabibrakhmanova V.R., Gurjanov O.P., Galeeva E.I., Trifonova T.V., Khamatgalimov A.R., Beckett R.P. & Minibayeva F.V. (2024): The roles of the anthraquinone parietin in the tolerance to desiccation of the lichen Xanthoria parietina: Physiology and anatomy of the pale and bright-orange thalli - International Journal of Molecular Sciences, 25(13): 7067 [11 p.]

Lichens are symbiotic organisms that effectively survive in harsh environments, including arid regions. Maintaining viability with an almost complete loss of water and the rapid restoration of metabolism during rehydration distinguishes lichens from most eukaryotic organisms. The lichen Xanthoria parietina is known to have high stress tolerance, possessing diverse defense mechanisms, including the presence of the bright-orange pigment parietin. While several studies have demonstrated the photoprotective … Read more...
