Kumar K., Mishra J.P.N. & Singh R.P. (2020): Usnic acid induces apoptosis in human gastric cancer cells through ROS generation and DNA damage and causes up-regulation of DNA-PKcs and γ-H2A.X phosphorylation, Chemico-Biological Interactions, 315: 108898

Usnic acid, a dibenzofuran derivative found in many lichen species, is reported to have anticancer activity against human gastric cancer. We investigated the molecular alterations associated with anticancer effects of usnic acid against human gastric adenocarcinoma AGS and gastric carcinoma SNU-1 cells. Usnic acid (10–25 μM) treatment to these cells caused a significant increase in mitochondrial membrane depolarization and apoptotic cells. Apoptosis induction was accompanied by an increase in … Read more...

Kemppinen J., Niittynen P., Aalto J., le Roux P.C. & Luoto M. (2019): Water as a resource, stress and disturbance shaping tundra vegetation, Oikos, 128(6): 811-822

Water is crucial for plant productivity and survival as a fundamental resource, but water conditions can also cause physiological stress and mechanical disturbance to vegetation. However, these different influences of water on vegetation patterns have not been evaluated simultaneously. Here, we demonstrate the importance of three water aspects (spatial and temporal variation of soil moisture and fluvial disturbance) for three ecologically and evolutionary distinct taxonomical groups (vascular plants, … Read more...

Yahr R., Royal Botanic Garden Edinburgh Genome Acquisition Lab, Darwin Tree of Life Barcoding collective et al. (2024): The genome sequence of a lichen-forming fungus, Platismatia glauca Linnaeus, 1753 [version 1; peer review: 2 approved], Wellcome Open Research, 9: 457

We present a genome assembly from a specimen of Platismatia glauca (lichen-forming fungus; Ascomycota; Lecanoromycetes; Lecanorales; Parmeliaceae). The genome sequence is 33.2 megabases in span. Most of the assembly is scaffolded into 21 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 95.06 kilobases in length. Keywords: Platismatia glauca, lichen-forming fungus, genome sequence, chromosomal, Lecanorales. Read more...

[Travkin V.P., Tsurykau A.G. & Korchikov E.S.] (2025): Новые находки лишайников и лихенофильных грибов на территории национального парка «Бузулукский бор» [New records of lichens and lichenicolous fungi in Buzuluk Bor (Pinewood) National Park], Вестник Оренбургского государственного педагогического университета [Vestnik of Orenburg State University], 53(1): 6–16

[in Russian with English abstract: ] The paper presents data on new findings, first discovered in the territory of the Buzuluk Bor (Pinewood) National Park, of which 8 species are lichens (Chaenotheca stemonea, Cladonia conista, C. grayi, C. monomorpha, Lecidella elaeochoma, Melanelixia glabratula, M. septentrionalis, Toninia populorum) and 2 species are lichenicolous fungi (Briancoppinsia cytospora, Pronectria leptaleae). Of these, Cladonia conista was first found in the south of European Russia, … Read more...

Ballová Z., Pekárik L., Píš V. & Šibík J. (2019): How much do ecosystem engineers contribute to landscape evolution? A case study on Tatra marmots, Catena, 182: 104121

Important influences of burrowing animals on ecosystems are reported from several environments. However, the impact of burrowing on alpine meadows has only been poorly studied. The largest and most widespread burrowing animals living in an alpine region are marmots. We tried to answer the following questions: Do marmots cause structural and compositional changes in alpine plant communities? Do marmots have a significant effect on soil properties? Do vegetation types differ according to their dependency … Read more...

Wang B., Duan Y.X., Wang W.F., Liu Z.Q., Li X.J., Liu Y., Li S.B. & Xi W. (2019): Greenhouse gas fluxes at different growth stages of biological soil crusts in eastern Hobq desert, China, Ying Yong Sheng Tai Xue Bao [The Journal of Applied Ecology], 30(3): 857-866

We analyzed greenhouse gas fluxes at the different growth stages of algae and lichen crusts in fixed sand with mobile dune as control in the eastern Hobq Desert, China, using the spatio-temporal substitution method. We explored the correlation of these fluxes with environmental factors and with biological soil crust growth. The results showed that variation of CO2 fluxes followed the order: lichen crust (128.5 mg·m-2·h-1) > algae crust (70.2 mg·m-2·h-1) > mobile dune (48.2 mg·m-2·h-1). CH4 … Read more...

(2019): Forest biomass, soil and biodiversity relationships originate from biogeographic affinity and direct ecological effects, Oikos, 128(11): 1653-1665

Ecosystem biomass, soil conditions and the diversity of different taxa are often interrelated. These relationships could originate from biogeographic affinity (varying species pools) or from direct ecological effects within local communities. Disentangling regional and local causes is challenging as the former might mask the latter in natural ecosystems with varying habitat conditions. However, when the species pool contribution is considered in statistics, local ecological effects might be detected. … Read more...

Güvenç Ş., Öztürk Ş. & Oran S. (2019): Epiphytic lichen diversity on Quercus pubescens Willd. in Bursa province, Biological Diversity and Conservation, 12(2): 51-56

The aim of this study is determined to compare the epiphytic lichen diversity of Quercus pubescens found in the center of the city or village, and away from the center. The ordination graph based on the settlements of species diversity located in the center of the city or village and away from the center were obtained with a detrended correspondence analysis (DCA). Differences in the species diversity and composition of the epiphytic lichens on Q. pubescens in the center of the city or village, and … Read more...
