Yavuz M. & Çobanoǧlu G. (2019): Active monitoring of airborne elements in Isparta Province (Turkey) with the epiphytic lichen Physcia aipolia (Erh. ex Humb.) Fürnr, Journal of Elementology, 24(3): 1115-1128

Air pollutants pose a threat to biodiversity throughout the world. This study was conducted to evaluate atmospheric element accumulation in Isparta city, including Gölcük Nature Park, located in the Western Mediterranean Region of Turkey. It is aimed to determine the air quality and potential pollutant sources in the region through lichen biomonitoring. Specimens of the epiphytic foliose lichen Physcia aipolia (Erh. ex Humb.) Fürnr. were sampled from 14 sites in the study area and analyzed by … EN Read more...

Bouchenak O., Yahiaoui K., Benhabyles N., Laoufi R. & Arab K. (2018): Preventive effect of Xanthoria parietina polyphenols on the complications of diabetes in white rat, Pakistan Journal of Pharmaceutical Sciences, 31(1)suppl.: 317–324

Polyphenols have shown antioxidant activity and an ability to prevent the toxic effects of oxidative stress in diabetes. The objective of this study was to evaluate the hypoglycemic and antioxidant effect of the methanolic extract of Xanthoria parietina on rats diabetes induced by streptozotocin (40 mg/g). The results obtained show that streptozotocin induces diabetes in the animal characterized by hyperglycemia, elevation of oxidative stress markers and a decrease of enzymatic and non-enzymatic … EN Read more...

Hanedar A., Güneş E., Kaykioğlu G., Çelik S.Ö. & Cabi E. (2020): Determination of polycyclic aromatic hydrocarbons in the soil, atmospheric deposition and biomonitor samples in the Meric-Ergene River Basin, Turkey, Environment, Development and Sustainability, 22: 3389–3406

In this study, the levels of polycyclic aromatic hydrocarbons (PAHs) were determined in various components in the Meric-Ergene River Basin which is one of Turkey’s intensive industrialization centers and which accordingly has faced significant environmental pollution and has about 1300 industrial plants within its boundaries. In the river basin, 16 USEPA PAHs were measured in a total of 192 samples consisting of soil, lichen, pine needle and total deposition samples for 1 year to represent the … URL EN Read more...

Tatipamula V.B., Polimati H., Gopaiah K.V., Babu A.K., Vantaku S., Rao P.R. & Killari K.N. (2020): Bioactive metabolites from manglicolous lichen Ramalina leiodea (Nyl.) Nyl., Indian Journal of Pharmaceutical Sciences, 82(2): 379-384

The chemical investigation of acetone extract of manglicolous lichen Ramalina leiodea yielded three known metabolites, methyl 2,6-dihydroxy-4-methyl benzoate (1), haematommic acid (2) and ethyl haematommate (3), which are reported for the first time in this species. The acetone extract and the metabolites (1-3) were screened for antioxidant activity in α,α-diphenyl-β-picrylhydrazyl, 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) and superoxide free radical assays, for antiinflammatory … URL EN Read more...

Mayrhofer H., Mašić E. & Bilovitz P.O. (2019): Additions and corrections to the “Catalogue of Lichenized and Lichenicolous Fungi from Bosnia and Herzegovina”, Phyton, 59(1-2): 55-67

The additions are based on an evaluation of 53 published sources concerning Bosnia and Herzegovina and on unpublished herbarium specimens. The actual lichen biota of the country includes 648 species (with 4 subspecies and 14 varieties) of lichenized, 13 non-lichenized or doubtfully lichenized, and 26 lichenicolous fungi.

Xu D., Pu Y. & Gou X. (2020): A semi-automated method to extract green and non-photosynthetic vegetation cover from RGB images in mixed grasslands, Sensors (Switzerland), 20(23): 6870

Green (GV) and non-photosynthetic vegetation (NPV) cover are both important biophysical parameters for grassland research. The current methodology for cover estimation, including subjective visual estimation and digital image analysis, requires human intervention, lacks automation, batch processing capabilities and extraction accuracy. Therefore, this study proposed to develop a method to quantify both GV and standing dead matter (SDM) fraction cover from field-taken digital RGB images with semi-automated … URL EN Read more...

Watts J.L., Raynor S.J. & Manzitto-Tripp E.A. (2025): Character evolution in Heterodermia s.l. (Physciaceae; Caliciales) and two new species from the southern Rocky Mountains, USA, Phytotaxa, 698(2): 61–81

Heterodermia Trevis. is a morphologically and taxonomically diverse genus of lichenized fungi with numerous centers of diversity worldwide. It is traditionally distinguished from other Physciaceae by a prosoplectenchymatous upper cortex and thick-walled spores; however, recent studies, both morphological and phylogenetic, have delimited new genera within Heterodermia s.l., adding complexity to traditional circumscription of the genus. Here, we present a study of the evolution of several key … URL EN Read more...

Sánchez-Esparza G.N., Pino-Bodas R., Ramírez-Cruz V., Villalobos-Arámbula A.R., Herrera-Campos M.A., Ruiz-Sánchez E., Bautista-González J.A. & Guzmán-Dávalos L. (2025): Phylogenetic position and genetic diversity of Cladonia jaliscana (Cladoniaceae, Lecanorales), Bryologist, 128(1): 43–58

Cladonia jaliscana is a lichen forming fungus, common, and abundant mainly in temperate forests of Mexico, which has received little attention in the literature. It is characterized by a conspicuous and persistent primary thallus, clavate podetia, red hymenial disc, and containing didymic and thamnolic acids as major substances. In this study we re-examine C. jaliscana from a morphological, chemical, and phylogenetic perspective. New specimens were collected from Durango, Jalisco, Veracruz, and Zacatecas, … URL EN Read more...

Usnetic acid is a dibenzofuran-2-ylacetic acid that can be obtained by alkaline degradation of a secondary lichen metabolite—usnic acid. In the present paper, the product of the reaction of usnetic acid with a mild fluorinating agent, Selectfluor®, was obtained. The structure of the product was proved by a set of physical methods, including 1H, 13C, 19F NMR, HMBC, HSQC, HRMS and IR spectroscopy. Keywords: usnetic acid; fluorination; Selectfluor®.
