Kelsey K.C., Pedersen S.H., Leffler A.J., Sexton J.O. & Welker J.M. (2023): Snow and vegetation seasonality influence seasonal trends of leaf nitrogen and biomass in Arctic tundra - Ecosphere, 14: e4515 [15 p.]

Climate change, including both increasing temperatures and changing snow regimes, is progressing rapidly in the Arctic, leading to changes in plant phenology and in the seasonal patterns of plant properties, such as tissue nitrogen (N) content and community aboveground biomass. However, significant knowledge gaps remain over how these seasonal patterns vary among Arctic plant functional groups (i.e., shrubs, grasses, and forbs) and across large geographical areas. We used three years of in situ field … URL EndNote PDF Read more...

Wang T., Shen C., Guo F., Zhao Y., Wang J., Sun K., Wang B., Chen Y. & Chen Y. (2021): Characterization of a polysaccharide from the medicinal lichen, Usnea longissima, and its immunostimulating effect in vivo - Int. J. Biol. Macromol., 181: 672-682

A polysaccharide, CSL-0.1, was isolated from the medicinal lichen, Usnea longissima. CSL-0.1 was a neutral rhamnose-containing glucogalactomannan with a molecular weight of 7.86 x 10(4) Da. The polysaccharide had a core mannan structure with (1 --> 6)-alpha-d-Manp units as the main chain and was substituted at the O-2 positions with side chains containing (1 --> 2)-alpha-d-Manp residue, [3)-alpha-Glcp(1 --> 4)-alpha-Glcp(1-->] and 6-O-substituted beta-d-Galf units. 2-O- and 2,3-di-O-substituted Rhap … URL EndNote PDF Read more...

Tatipamula V. & Annam S. (2022): Antimycobacterial activity of acetone extract and isolated metabolites from folklore medicinal lichen Usnea laevis Nyl. against drug-sensitive and multidrug-resistant tuberculosis strains - J. Ethnopharmacol., 282: 114641

ETHNOPHARMACOLOGICAL RELEVANCE: Tuberculosis (Tb) is one of the most infectious diseases caused by Mycobacterium tuberculosis (M.t) with almost 2 million deaths yearly. Although many Tb control programs have been organised, there is an elevated number of Tb cases due to the appearance of extremely drug-resistant and multidrug-resistant (MDR) Tb strains. In the cultures of Venezuelan Andes, fruticose lichen Usnea laevis Nyl. (Usneaceae) with folklore name 'Barba de Piedra, Tusinya' is used as a natural … URL EndNote PDF Read more...

Wang Q., Li J., Yang J., Zou Y. & Zhao X. (2022): Diversity of endophytic bacterial and fungal microbiota associated with the medicinal lichen Usnea longissima at high altitudes - Front. Microbiol., 13: 958917

Endophytic microbial communities of lichen are emerging as novel microbial resources and for exploration of potential biotechnological applications. Here, we focused on a medicinal lichen Usnea longissima, and investigated its bacterial and fungal endophytes. Using PacBio 16S rRNA and ITS amplicon sequencing, we explored the diversity and composition of endophytic bacteria and fungi in U. longissima collected from Tibet at five altitudes ranging from 2,989 to 4,048 m. A total of 6 phyla, 12 classes, … URL EndNote PDF Read more...

Water repellent soils represent some of the most responsive natural surfaces from the point of view of overland flow generation. Measurement of the runoff response of such soils can therefore provide characteristics that can help constrain hydrological models or improve the conceptual models of hillslope runoff generation. We have analysed the overland flow characteristics of water repellent sandy soils at three sites with different dominant vegetation (hereafter denoted as the lichen, moss and herb … URL EndNote Read more...

Holt E.A., Jonas I. & Stechelin M. (2023): Inequity in authorship of North American lichens - Bryologist, 126(2): 205–216

Women have long been underrepresented in the sciences, and their contributions are often overlooked. Previous work has demonstrated a significant productivity gap between men and women when investigating vascular plant authorities and the naming of plant taxa. No study has directly investigated gender inequity, as depicted through authority identity, in the field of lichenology. Our research goal was to describe patterns in gender identity and country of origin for authors of North American … URL EndNote Read more...

Navarro-Rosinés P. & Romero C. (2019): Sclerococcum stigma (Dactylosporaceae) una nueva combinación para Dactylospora stigma, un hongo liquenícola olvidado que crece sobre Porpidia macrocarpa - Revista Catalana de Micologia, 40: 35–42

Sclerococcum stigma (Dactylosporaceae) a new combination for Dactylospora stigma, a forgotten lichenicolous fungus that grows on Porpidia macrocarpa. A new combination, Sclerococcum stigma (Rehm) Nav.-Ros. & Romero, is proposed to include Dactylospora stigma (Rehm) Rehm ex Arnold, a lichenicolous fungus that grows on Porpidia macrocarpa in different localities in the Alps (Swabia and Austrian Tyrol) and the Pyrenees (Catalonia). A detailed description of the species is included, and it is … EndNote PDF Read more...

In this contribution, new data concerning lichen-forming and lichenicolous fungi in Ukraine are presented. It includes new record, exclusions, and confirmations to the Ukrainian administrative regions of 64 species of lichen-forming and 20 species of lichenicolous fungi in the 57 genera of Acarospora, Agonimia, Arthonia, Bacidia, Botryolepraria, Caloplaca, Candelaria, Ceratobasidium, Circinaria, Clauzadea, Coenogonium, Endococcus, Epithamnolia, Erythricium, Flavoplaca, Illosporiopsis, Intralichen, … URL EndNote PDF Read more...

Llewellyn T., Mian S., Hill R., Leitch I.J. & Gaya E. (2023): First whole-genome sequence and flow cytometry genome size data for the lichen-forming fungus Ramalina farinacea (Ascomycota) - Genome Biology and Evolution, 15(5): evad074 [7 p.]

Lichen-forming fungi are a diverse and ecologically important group of obligate mutualistic symbionts. Due to difficulties with maintaining them in culture and their extremely slow growth, lichenologists are increasingly opting for metagenomic sequencing followed by symbiont genome separation using bioinformatic pipelines. However, without knowing the true genome size of the lichen-forming fungus, we cannot quantify the completeness of the genome assembly and the efficacy of the bioinformatic filtering. … URL EndNote PDF Read more...
