Fjelde M.O., Timdal E., Haugan R. & Bendiksby M. (2024): Paraphyly and cryptic diversity unveils unexpected challenges in the “naked lichens” (Calvitimela, Lecanoromycetes, Ascomycota) - Molecular Phylogenetics and Evolution, 190: 107944 [16 p.]

Molecular phylogenetics has revolutionized the taxonomy of crustose lichens and revealed an extensive amount of cryptic diversity. Resolving the relationships between genera in the crustose lichen family Tephromelataceae has proven difficult and the taxon limits within the genus Calvitimela are only partly understood. In this study, we tested the monophyly of Calvitimela and investigated phylogenetic relationships at different taxonomic levels using an integrative taxonomic approach. We performed … Read more...

Partemi R., Debortoli N., Martínez A., Kamburska L., Souffreau C., Matheve H., Vantieghem P., De Meester L., van Doninck K., Merckx T. & Fontaneto D. (2024): Weak effect of urbanization on bdelloid rotifers living in lichens - R Soc Open Sci, 11(4): 231978

Human activities have an overwhelming impact on the natural environment, leading to a deep biodiversity crisis whose effects range from genes to ecosystems. Here, we analysed the effect of such anthropogenic impacts on bdelloid rotifers (Rotifera Bdelloidea), for whom these effects are poorly understood. We targeted bdelloid rotifers living in lichen patches across urbanization gradients in Flanders and Brussels (Belgium). Urbanization was measured as the percentage of built-up area (BU) across different … Read more...

Bukabayeva Z., Abiyev S., Silybayeva B. & Ivachshenko O. (2024): The impact of climate aridification on rare lichen communities - Biosystems Diversity, 32(1): 142-149

The global diversity of approximately 25,000 lichen species (e.g., from the genera Usnea, Cladonia, and Peltigera), including rare and endangered ones, highlights the importance of preserving their population in the State National Nature Park “Burabay”. The objective of this study was to investigate the distribution of rare lichen species in the territory of the State National Nature Park “Burabay,” located in the Akmola region of Kazakhstan, in the period from 2018 to 2022, with a particular … Read more...

Lee Y., Jang H.-R., Lee D., Lee J., Jung H.-R., Cho S.-Y. & Lee H.-Y. (2024): Graphislactone A, a fungal antioxidant metabolite, reduces lipogenesis and protects against diet-induced hepatic steatosis in mice - International Journal of Molecular Sciences, 25(2): 1096 [16 p.]

Graphislactone A (GPA), a secondary metabolite derived from a mycobiont found in the lichens of the genus Graphis, exhibits antioxidant properties. However, the potential biological functions and therapeutic applications of GPA at the cellular and animal levels have not yet been investigated. In the present study, we explored the therapeutic potential of GPA in mitigating non-alcoholic fatty liver disease (NAFLD) and its underlying mechanisms through a series of experiments using various cell lines … Read more...

Bhagarathi L.K., Da Silva P.N.B. & Subramanian G. (2024): Lichen-host plant specificity on citrus plant species in coastal agroecosystems at No. 63 Benab, Berbice, Guyana - World Journal of Advanced Research and Reviews, 21(1): 2342–2355

This was a preliminary study into host-plant lichen specificity at two coastal agroecosystems sites at No. 63 Benab, Berbice, Guyana. For each of the two sites, sampling plots of 2000 meter square (2000 m2) were demarcated and at 50 m × 40 m study plots were established. Healthy mature trees were identified in each plot to assess the lichen communities host-plant specificity. Twine was used to mark the trunks of 40 healthy individual trees in the North, South, East, and West quadrants (each measuring … Read more...

Clayden S., Driscoll K.E. & Harries H. (2024): The lichen genus Rinodina (Physciaceae) in New Brunswick, Canada - The Canadian Field-Naturalist, 137[2013]: 32–63

Fifteen species of the crustose lichen genus Rinodina are confirmed in New Brunswick, Canada. We report four corticolous species, Rinodina pachysperma, Rinodina populicola, Rinodina septentrionalis, and Rinodina tenuis, and the saxicolous Rinodina tephraspis in the province for the first time. A previous report of Rinodina granuligera is based on a specimen that we have re-identified as Rinodina cinereovirens. We note distinguishing characteristics, habitats, substrata, relative abundance, and biogeographic … Read more...

Islary P., Meher R.K., Biswas S., Basumatary D., Basumatary I.B., Dubey D., Basumatary D. & Daimari R. (2024): Evaluation of anticancer, immunomodulatory and anti-inflammatory potential of antioxidant rich Anzia ornatoides, a lichen species from eastern Himalayan region - South African Journal of Botany, 164: 266–279

The lichen Anzia ornatoides was identified by its morpho-anatomical and chemical features. The hexane, diethyl ether, ethyl acetate, methanol, and water extracts of the lichen were assessed for their antioxidant capacities. The presence of various phyto-compounds of the methanol extract were run through a GC–MS and identified three major compounds viz. methyloxyolivetol, imidazole 2-t‑butyl‑1,4-dimethyl-5-phenyl and benzoic acid 2,4-dihydroxy-3,6-dimethyl-methyl ester. The crude extraction … Read more...

Božič D. & Horvat M. (2024): Insights into seasonal variations in mercury isotope composition of lichens - Environmental Pollution, 340: 122740

Lichens are commonly used to assess mercury (Hg) concentrations in air because of their cost-effectiveness. However, recent research has revealed temporal variations in the isotopic composition of Hg. Previous work on this topic leaves open questions about the repeatability of data over multiple seasons, different types of sampling (transplantation or in-situ collection), and diverse locations. This study aims to address these issues by conducting a high-frequency sampling campaign of in-situ and … Read more...

Silva T.E.F., da Silva M.S.R.C., dos Santos M.A.L., Cáceres M.E.S., Aptroot A. & Vitória N.S. (2024): Two new Arthoniales species (lichenized Ascomycota) from Brazil - Revista de Gestão Social e Ambiental, 18(4): e04543 [13 p.]

Objective: The present work aimed to describe, comment, and illustrate two new lichenized species of Ascomycota. Method: Morphological analyses of the samples were performed at the Laboratory in the State University of Bahia (UNEB), Campus VIII. The lichen thalli were observed using a stereomicroscope (Zeiss); chemical treatments were performed to observe the microscopic structures of the lichens after exposure to 10% KOH (potassium hydroxide), lactophenol (cotton blue), Melzer’s reagent, chlorine, … Read more...

Thiers B.M. (2024): Strengthening partnerships to safeguard the future of herbaria - Diversity, 16(1): 36 [10 p.]

Herbaria remain the primary means of documenting plant life on earth, and the number of herbaria worldwide and the number of specimens they hold continues to grow. Digitization of herbarium specimens, though far from complete, has increased the discoverability of herbarium holdings and has increased the range of studies from which data from herbarium specimens can be used. The rather large number of herbaria about which no current information is available is a source of concern, as is herbarium consolidation … Read more...
