Preethi S.J., Yamuna A., Arunkumar M., Murugesh E., Ponmurugan P. & Shanmughavel P. (2026): Computational screening of lichen bioactive compounds as a potential antiviral agent against SARS-CoV-2 main proteases, In Silico Pharmacology, 14: 78 [16 p.]

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a highly transmissible novel coronavirus, sparked the global pandemic, COVID-19, in 2020. Research primarily targeted specific drugs to block this virus, with natural products emerging as promising and reliable treatments. Lichens represent a valuable source of antiviral drugs. Specific secondary metabolites present in lichens with known antiviral properties have been researched. The current work focussed on the molecular docking of antiviral … Read more...

Ali W., Choe K., Nasir T., Atiq U., Tahir M., Ahmad W., Park H.Y., Park T.J. & Kim M.O. (2026): Atraric acid mitigates the cognitive and pathological deficits in mice via Aβ1−42 induced Alzheimer’s disease, Inflammopharmacology, 34: 2693–2704

Alzheimer’s disease (AD) is a neurological disease that leads to cognitive deficits in aged people. There are numerous pathological hallmarks, among them the classical hallmark is β-Amyloid (Aβ), which induces inflammatory events and phagocytic ability of phagocytic cells (such as microglial cells). Until now, the role of atraric acid (AA) in the prevention of AD has not been reported. The study was designed to investigate the contribution of AA to Aβ-induced microglial activation and cognitive … Read more...

Boonpeng C., Sangiamdee D., Pischom M., Butrid P., Noikrad S. & Boonpragob K. (2026): Assessment of atmospheric potentially toxic elements in urban and mountainous regions of northern Thailand using lichen transplants, Environmental Science and Pollution Research, 33: 5148–5159

Lichen transplants are effective tools used to biomonitor airborne potentially toxic elements (PTEs) in urban and natural areas. The main objective of this study was to measure atmospheric PTE concentrations during the dry period in the urban and mountainous areas of Chiang Mai Province using lichen transplants. Samples of the lichen Parmotrema tinctorum (Despr. ex Nyl.) Hale were collected from a remote area and exposed at 18 sites in the Chiang Mai urban area and Doi Suthep-Pui National Park for … Read more...

Virolainen P., Pankova V., Nerezenko A. & Chekunova E. (2026): Structural features of algal and fungal GATA transcription factors may play a role in symbiosis, Journal of Molecular Evolution, 94: 383–404

Algal-fungal symbiotic relationships are widespread in nature and promote the evolution of both partners. The best-known example of such symbiosis is lichen, a mutualistic association of a mycobiont and a photobiont. Long-term interactions may lead to the formation of new cooperative molecular mechanisms or changes in the genetics of the symbionts. Symbiosis establishment includes the fine-tuning of partner metabolism by transcriptional regulators. GATA family transcription factors have proven to … Read more...

Carmona-Higuita M.J., García-Arias M., Duque-Trujillo J.F. & Benavides A.M. (2026): Integrating magnetic and elemental analyses to evaluate epiphytes as biomonitors of urban air pollution in a tropical city (Medellín, Colombia), Environmental Monitoring and Assessment, 198: 386 [15 p.]

Urban air pollution is a major challenge for environmental health, especially in tropical cities where complex topography and fossil fuel dependence exacerbate poor air quality. Epiphytes, which rely on atmospheric water and nutrients, are particularly sensitive to airborne contaminants and represent promising biomonitors. This study compares the potential of vascular and non-vascular epiphytes to accumulate airborne pollutants, providing a direct assessment of their biomonitoring performance. We … Read more...

Beard C., Sancho L.G., Vivas M., Hogg I.D., Brabyn L., Cary S.C. & Green T.G.A. (2026): Lichen growth rates over 51 years at Cape Hallett, Northern Victoria Land, support a large (100x) cline across Antarctica, Polar Biology, 49: 35 [10 p.]

Crustose lichens show a very large (roughly 100 times) growth rate cline across Antarctica from some of the lowest known growth rates in the McMurdo Dry Valleys (78° S) to near fastest in the maritime Livingston Island, 63° S. This gradient, which correlates with changes in temperature and precipitation, provides an ideal opportunity to monitor climate-driven change across Antarctica. Although the cline is based on reasonably large sample sizes at its geographic limits, a central site at Cape Hallett … Read more...

Moseev D.S., Kotova E.I. & Suetin Y.A. (2026): Metal accumulation by the lichen Flavocetraria nivalis on the coast of the southern part of Vaygach Island, Contemporary Problems of Ecology, 19: 261–268

[original Russian Text published in Sibirskii Ekologicheskii Zhurnal, 2026, No. 2, pp. 324–334.] The results of the accumulation of metals by the epigeal lichen Flavocetraria nivalis, which is widespread on Vaygach Island, are presented. Lead–zinc ore deposits are one of the sources of environmental pollution on the island. However, the influence of lead–zinc ore mines on metal concentrations in F. nivalis has not been established, since the metal content in lichen only increased with distance … Read more...

Meysurova A.F. (2026): Comparative analysis of morphophysiological responses of the lichen Parmelia sulcata and the moss Orthotrichum speciosum to simulated acidic and ammonium air pollution, Contemporary Problems of Ecology, 19: 251–260

[original Russian Text published in Sibirskii Ekologicheskii Zhurnal, 2026, No. 2, pp. 312–323.] This study presents the results of a model experiment investigating the effects of atmospheric pollutants – sulfuric and nitric acids, ammonium sulfate, and ammonium nitrate – on the epiphytic organisms Parmelia sulcata and Orthotrichum speciosum. The experiment simulated the deposition of polluted atmospheric precipitation. The assessment included spectrophotometric analysis of photosynthetic … Read more...

Osyczka P., Kościelniak R. & Stanek M. (2026): Forest interior versus forest edge: the influence of microclimatic conditions on the functioning of epiphytic lichens—inference from a three-year transplant experiment, European Journal of Forest Research, 145: 59 [16 p.]

Lichens contribute to increasing biodiversity in forests and have a substantial impact on forest dynamics, including water cycling and microclimate shaping. Natural disturbances, ongoing climate change, forestry practices, and habitat fragmentation disrupt the structural complexity of the woodland landscape, posing a serious threat to sensitive stenoecious species. Long-term studies on the acclimation abilities and physiological response of lichens to altered microclimatic conditions at the local … Read more...

Dong Z., Sun M.S., He Y.D., Zhou L., Xiang W., Yao X., Huang P. & Zeng J.G. (2026): Fungal photobiont and microbiome genome composition in the Cladonia uncialis tripartite symbiosis, Scientific Data, 13: 319 [12 p.]

As symbiotic complexes formed through the association of bacteria or algae with fungi, lichens exhibit exceptional adaptability to extreme environments and function as pioneer species in rocky habitat ecological succession. The absence of high quality chromosome-level genome has constrained investigations into lichen adaptive evolution, while functional contributions of symbiotic bacterial communities remain inadequately explored. This study presents the chromosome-level genome assembly of the mycobiont … Read more...
