Frolov I.V. & Prokopiev I.A. (2023): The poorly known in Russia sporodochial lichen genus Sporodophoron (Arthoniaceae) with one species new to the country and continental Eurasia - Turczaninowia, 26(1): 136-144

The genus Sporodophoron (Arthoniaceae, lichenized Ascomycota) is characterized by whitish, convex, and usually discrete or rarely becoming confluent sporodochia and conidia formed in zigzag-shaped and occasionally branched chains. It consists of four species, and only S. primorskiense was known in Russia, in a single locality in the Primorye Territory. Here we report the second locality of S. primorskiense and two localities of new to Russia S. gossypi-num, all from the deciduous and mixed forests … URL EndNote PDF Read more...

Killari K., Polimati H., Prasanth D., Singh G., Panda S., Vedula G. & Tatipamula V. (2023): Salazinic acid attenuates male sexual dysfunction and testicular oxidative damage in streptozotocin-induced diabetic albino rats - Rsc Advances, 13(19): 12991-13005

Male sexual dysfunctions such as infertility and impotence are recognized as the consequences of diabetes. Salazinic acid (Sa) is a depsidone found in lichen genera of Lobaria, Parmelia, and Usnea, which has prominent free radical and alpha-glucosidase inhibitory actions. The present study establishes the beneficial role of salazinic acid (Sa) to combat the deleterious effects of streptozotocin-induced diabetes on the male reproductive system of rats. In a dose-dependent manner, Sa significantly … URL EndNote PDF Read more...

Marty C., Fradette O., Duchesne L., Faubert P., Ouimet R. & Villeneuve C. (2023): Natural regeneration potential and dynamics in boreal lichen woodlands of eastern Canada following soil scarification - Frontiers in Forests and Global Change, 6: E0yw5

Boreal lichen woodlands (LWs) are stable low tree-density zones of the Canadian boreal forest whose afforestation has been proposed as a way to create new C sinks and thus mitigate climate change. Planting operations in these remote areas are however costly and time-consuming, and may not be necessary when soil scarification is followed by dense natural regeneration. In the present study, we assessed the natural regeneration potential and dynamics in six boreal LWs of Quebec, Canada, 11 years after … URL EndNote PDF Read more...

Tanaka M., Baek S., Tochigi K., Naganuma T., Inagaki A., Dewi B. & Koike S. (2023): Conditions affecting ant nesting in stumps in a temperate coniferous planted forest - Forest Ecology and Management, 537: E1yx8

Dead trees are an important component of forest ecosystems as they play various roles in these ecosystems and their biodiversity. The use of dead trees as a habitat and foraging resource by various organisms affects the decomposition of the trees. Ants use dead trees as nests and slow their decomposition by weakening the function of decomposers, such as fungi and termites, through interspecific interactions. However, our understanding of the characteristics of dead trees in which ants nest and the … URL EndNote PDF Read more...

Boonpeng C., Sangiamdee D., Noikrad S. & Boonpragob K. (2023): Lichen biomonitoring of seasonal outdoor air quality at schools in an industrial city in Thailand - Environmental Science and Pollution Research, 30: 59909–59924

Poor air quality in school environments causes adverse health effects in children and decreases their academic performance. The main objective of this study was to use lichens as a biomonitoring tool for assessing outdoor air quality at schools in the industrial area of Laem Chabang municipality in Thailand. Thalli of the lichen Parmotrema tinctorum were transplanted from an unpolluted area to nine schools in the industrial area and to a control site. The lichens were exposed for four periods in … URL EndNote PDF Read more...

Pradhan S., Dash S., Parida S., Sahoo B. & Rath B. (2023): Antioxidant and antimicrobial activities and GC/MS-based phytochemical analysis of two traditional Lichen species Trypethellium virens and Phaeographis dendritica - Journal of Genetic Engineering and Biotechnology, 25(1): 41 [18 p.]

Lichens are complex plants living in symbiotic relationship between fungi and algae. They are used for human and animal nutrition and are used in folk medicine in many countries over a considerable period of time. In the present study, various solvent extracts of Trypethelium virens and Phaeographis dendritica were tested for their antioxidant and antimicrobial activity. The phytochemical analysis by GC/MS revealed phenolics (1.273%), terpene (0.963%), hydrocarbons (2.081%), benzofurans (2.081%), … URL EndNote Read more...

Ren M., Jiang S., Wang Y., Pan X., Pan F. & Wei X. (2023): Discovery and excavation of lichen bioactive natural products - Frontiers in Microbiology, 14: 1177123

Lichen natural products are a tremendous source of new bioactive chemical entities for drug discovery. The ability to survive in harsh conditions can be directly correlated with the production of some unique lichen metabolites. Despite the potential applications, these unique metabolites have been underutilized by pharmaceutical and agrochemical industries due to their slow growth, low biomass availability, and technical challenges involved in their artificial cultivation. At the same time, DNA sequence … URL EndNote PDF Read more...

Rinas C.L., McMullin R.T., Rousseu F. & Vellend M. (2023): Diversity and assembly of lichens and bryophytes on tree trunks along a temperate to boreal elevation gradient - Oecologia, 202: 55–67

Based on hypotheses related to environmental filtering vs. stochastic community assembly, we tested taxon-specific predictions regarding the relationships of alpha diversity, beta diversity and species composition of epiphytic macrolichens and bryophytes with elevation and the lateral gradient on trees (the different sides of the tree bole related to aspect and trunk inclination) at Parc national du Mont-Megantic in Southeastern Quebec, Canada. For lichens on firs, increasing elevation was associated … URL EndNote PDF Read more...

Nagar S., Pigott M., Kukula-Koch W. & Sheridan H. (2023): Unravelling novel phytochemicals and anticholinesterase activity in Irish Cladonia portentosa. - Molecules, 28(10): 4145 [22 p.]

Acetylcholinesterase inhibitors remain the mainstay of symptomatic treatment for Alzheimer’s disease. The natural world is rich in acetylcholinesterase inhibitory molecules, and research efforts to identify novel leads is ongoing. Cladonia portentosa, commonly known as reindeer lichen, is an abundant lichen species found in Irish Boglands. The methanol extract of Irish C. portentosa was identified as an acetylcholinesterase inhibitory lead using qualitative TLC-bioautography in a screening program. … URL EndNote PDF Read more...
