Yenigun S., Ipek Y., Marah S., Demirtas I. & Ozen T. (2024): DNA protection, molecular docking, antioxidant, antibacterial, enzyme inhibition, and enzyme kinetic studies for parietin, isolated from Xanthoria parietina (L.) Th. Fr. - Journal of Biomolecular Structure and Dynamics, 42(2): 848–862

Parietin was isolated from Xanthoria parietina (L.) Th. Fr.’ (methanol:chloroform) extract, using a silica column. 13 C NMR and 1H NMR were used to confirm the structure of the isolated parietin. For the first time, parietin was investigated for its antioxidant, antibacterial and DNA protective activities. Molecular docking was carried out to determine the binding affinity and interactions between the enzymes and our molecule. Inhibition and kinetic mechanism studies for the action of the enzymes were … Read more...

Buril M.L.L., de Oliveira Silva A.K., Martins M.C.B., Silva H.P.B., Aptroot A., da Silva B.F. & Pereira E.C. (2024): Species of Peltula (lichenized Ascomycota) are shown to tolerate rock substrate rich in natural γ-radiation in NE Brazil - Total Environment Advances, 10: 200099 [9 p.]

Pedra Municipality in Pernambuco State (Northeastern Brazil) is known for encompassing areas with high natural radiation from 238U sources, contaminating soil, atmosphere, water, vegetation, and animals, including rural activities. A lichen survey was performed in the area, and species belonging to 19 genera were identified. The diversity is considered very low when compared to nearby municipalities and other similar regions, which might indicate the effect of radiation on the environment. The lichen … Read more...

Cui C., Li Y., Xu J., Zhao X. & Jia Z. (2024): Diorygma tiantaiense sp. nov. and a checklist and key to Diorygma species from China - Diversity, 16(4): 213 [12 p.]

A new species Diorygma tiantaiense Z.F. Jia, sp. nov. was found, which is characterized by a corticolous thallus with norstictic acid, oval or oblong apothecia, immersed to ± raised discs with white pruina, and large muriform ascospores (120–210 × 35–60 µm). Detailed morphological descriptions, photographs, and a comparison and discussion of similar species are provided. A checklist and key to the species of Diorygma known from China is presented. Keywords: lichenized fungi; lecanoromycetes; … Read more...

Beck K., Glew K., Hardman A., Lavdovsky N., McCune B., Nelson N., Ponzetti J., Rhoades F., Rosentreter R., Stone D., Theden T., Tønsberg T. & Villella J. (2024): Lichens of Cypress Island, Washington – the seen and the unseen - Evansia, 40(4): 136–155

A group of Northwest Lichenologists explored the lichen biodiversity on Cypress Island in the San Juan Islands on the Pacific coast north of Seattle, hosted by the Washington Department of Natural Resources. We compiled our observations separately by habitat: (1) uplands with serpentine bedrock, (2) uplands with basalt bedrock, and (3) rocky saltwater shorelines. Combining our results with previous efforts, we report 243 lichen species from Cypress Island. Despite the respectable species list, we … Read more...

Best I.N., Brown L., Elkin C., Finnegan L., McClelland C.J.R. & Johnson C.J. (2024): Cut vs. fire: a comparative study of the temporal effects of timber harvest and wildfire on ecological indicators of the boreal forest - Landscape Ecology, 39: 81 [22 p.]

Context: Large-scale natural disturbances are crucial drivers of ecosystem function and composition for many forested ecosystems. In the last century, the prevalence of anthropogenic disturbances has increased across Canada’s boreal forest. Habitat disturbance from timber harvest and wildfire is linked to declines of boreal species, including woodland caribou (Rangifer tarandus caribou). Objectives: We tested how disturbances influenced the recovery trajectory of ecological indicators of timber, … Read more...

Andersen R., Fernandez-Garcia P., Martin-Walker A., Klein D., Marshall C., Large D.J., Hughes R. & Hancock M.H. (2024): Blanket bog vegetation response to wildfire and drainage suggests resilience to low severity, infrequent burning - Fire Ecology, 20: 26 [16 p.]

Background: In 2019, a wildfire impacted an area of blanket bog and wet heath > 60 km2 in the Flow Country peatlands of northern Scotland, a site of global significance. Unusually the footprint of the wildfire included discrete areas of degraded, restored, and near-natural blanket bogs. Following the wildfire, we surveyed vegetation in 387 quadrats in burnt and unburnt areas. The study aimed to determine whether and how proximity to human-made drains and microtopography affected fire-vegetation … Read more...

(2024): The Arctic Plant Aboveground Biomass Synthesis Dataset - Scientific Data, 11: 305 [13 p.]

Plant biomass is a fundamental ecosystem attribute that is sensitive to rapid climatic changes occurring in the Arctic. Nevertheless, measuring plant biomass in the Arctic is logistically challenging and resource intensive. Lack of accessible field data hinders efforts to understand the amount, composition, distribution, and changes in plant biomass in these northern ecosystems. Here, we present The Arctic plant aboveground biomass synthesis dataset, which includes field measurements of lichen, bryophyte, … Read more...

Manninen O.H., Myrsky E., Tolvanen A. & Stark S. (2024): N-fertilization and disturbance exert long-lasting complex legacies on subarctic ecosystems - Oecologia, 204: 689–704

Subarctic ecosystems are subjected to increasing nitrogen (N) enrichment and disturbances that induce particularly strong effects on plant communities when occurring in combination. There is little experimental evidence on the longevity of these effects. We applied N-fertilization (40 kg urea-N ha−1 year−1 for 4 years) and disturbance (removal of vegetation and organic soil layer on one occasion) in two plant communities in a subarctic forest-tundra ecotone in northern Finland. Within the first … Read more...

Liang X., Chen W., Jiang B. & Xiao C.-J. (2024): Dibenzofurans from nature: Biosynthesis, structural diversity, sources, and bioactivities - Bioorganic Chemistry, 144: 107107 [17 p.]

Dibenzofurans are a small class of natural products with versatile biological activities that used to be thought to come mainly from lichens and ascomycetes. In fact, they are also distributed widely in higher plants, especially in the families Rosaceae and Myrtaceae. Dibenzofurans and derivatives from lichens and ascomycetes have been well reviewed, but dibenzofurans from all biological sources in nature have not been reviewed. In this review, dibenzofurans from all natural sources have been comprehensively … Read more...

Wilk K. & Lücking R. (2024): Quantitative integrative taxonomy informs species delimitation in Teloschistaceae (lichenized Ascomycota): the genus Wetmoreana as a case study - IMA Fungus, 15: 9 [42 p.]

The genus Wetmoreana was studied using quantitative integrative taxonomy methods to resolve the genus delimitation and explore its taxonomy diversity at the species level. As a result, the genus Fulgogasparrea is synonymized with Wetmoreana, and the latter includes 15 formally described species, one subspecies, and three further, thus far undescribed species: W. appressa, W. awasthii comb. nov., W. bahiensis sp. nov., W. brachyloba comb. nov., W. brouardii, W. chapadensis comb. nov., W. circumlobata … Read more...
