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, … URL EndNote PDF 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 … URL EndNote PDF 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 … URL EndNote PDF 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 … URL EndNote PDF Read more...

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 … URL EndNote Read more...

Bioremediation utilizes living organisms such as plants, microbes and their enzymatic products to reduce toxicity in xenobiotic compounds. Microbial-mediated bioremediation is cost effective and sustainable and in situ application is easily implemented. Either naturally occurring metabolic activity can be utilized during bioremediation for the degradation, transformation or accumulation of substances, or microbial augmentation with non-native species can be exploited. Despite the perceived low potential … URL EndNote PDF Read more...

Ndhlovu N.T., Minibayeva F. & Beckett R.P. (2024): A role for secondary metabolites in desiccation tolerance in lichens - Microbiology Research, 15(1): 225–235

In lichens, secondary metabolites have been shown to protect against biotic stresses such as pathogen attacks and grazing, and abiotic stresses such as ultraviolet (UV) and high photosynthetically active radiation (PAR). Lichen secondary metabolites are known to have strong antioxidant activity, and while theoretically they may have roles in tolerance to other abiotic stresses, these roles remain largely unclear. Here, we used the acetone rinsing method to harmlessly remove most of the secondary … URL EndNote PDF Read more...

Osyczka P., Kościelniak R. & Stanek M. (2024): Old-growth forest versus generalist lichens: Sensitivity to prolonged desiccation stress and photosynthesis reactivation rate upon rehydration - Mycologia, 116(1): 31–43

Most epiphytic lichens demonstrate high specificity to a habitat type, and sensitive hygrophilous species usually find shelter only in close-to-natural forest complexes. Some of them are considered as old-growth forest and/or long ecological continuity indicators. To evaluate general links between the narrow ecological range and physiological traits, two distinct sets of model lichens, i.e., old-growth forest (Cetrelia cetrarioides (Duby) W.L. Culb. & C.F.

Zhang Y., Yin Y., Wang L., Printzen C., Wang L. & Wang X. (2024): Two new species of Rhizoplaca (Lecanoraceae) from Southwest China - MycoKeys, 101: 233–248

In this study, two new species, Rhizoplaca adpressa Y. Y. Zhang & Li S. Wang and R. auriculata Y. Y. Zhang, Li S. Wang & Printzen, are described from Southwest China, based on their morphology, phylogeny and chemistry. In phylogeny, the two new species are monophyletic, and sister to each other within Rhizoplaca chrysoleuca-complex. Rhizoplaca adpressa is characterized by its placodioid and closely adnate thallus, pale green and heavily pruinose upper surface, narrow (ca. 1 mm) and white free margin … URL EndNote PDF 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 … URL EndNote PDF Read more...
