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 … 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 … 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The additions are based on an evaluation of 53 published sources concerning Bosnia and Herzegovina and on unpublished herbarium specimens.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. Read more...

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 … 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 … 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, … Read more...

Filimonov A.S., Zernov S.P., Luzina O.A. & Salakhutdinov N.F. (2025): (3a,8b)-5-Acetyl-3a-fluoro-6,8-dihydroxy-7,8b-dimethyl-3,3a-dihydrofuro[3,2-b]benzofuran-2(8bH)-one, Molbank, 2025(2): M1995 [6 p.]

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®.

Armstrong R.A. (2019): The lichen symbiosis, lichen 'extremophiles' and survival on Mars, Journal of Astrobiology and Space Science Reviews, 1: 378-397

There continues to be speculation regarding whether lichens could survive on Mars. Lichens have been described as %91extremophiles%92 and could potentially withstand some aspects of the hostile environment of the planet especially if they are %91endolithic%92 and live within the rocks as in some deserts and dry valleys in Antarctica. Lichens, however, are composite organisms and their existence assumes the successful establishment of a variety of microorganisms on Mars including eukaryotic green … Read more...

AL-Alam J., Chbani A., Faljoun Z. & Millet M. (2019): The use of vegetation, bees, and snails as important tools for the biomonitoring of atmospheric pollution—a review, Environmental Science and Pollution Research, 26(1): 9391–9408

The continuous discharge of diverse chemical products in the environment is nowadays of great concern to the whole world as some of them persist in the environment leading to serious diseases. Several sampling techniques have been used for the characterization of this chemical pollution, although biomonitoring using natural samplers has recently become the technique of choice in this field due to its efficiency, specificity, and low cost. In fact, several living organisms known as biomonitors could … Read more...

Mohamed E., Mohammed L. & Abdelhay E.G. (2020): Using calcicolous and corticolous lichens to assess lead and cadmium air pollution of the Moroccan Atlantic Coast Safi-Essaouira, Polish Journal of Environmental Studies, 29(1): 779-787

Air pollution by metallic trace elements (MTE) has evolved in recent years in Moroccan cities – especially those with significant industrial activities. Biological tools, especially the use of lichens as a bioindicator of heavy metal air pollution, have been receiving world-wide attention. This study aims to evaluate atmospheric pollution of the Moroccan Atlantic coastline Safi-Essaouira using lichen as monitors of atmospheric metal contamination. Thus, two trace elements (lead and cadmium) were … Read more...
