Rajeswari V., Gunasekar B., Chinnasamy S. & Mathew M. (2022): Effect of (+) usnic Acid on Pigment Production in Bacteria, J Pure Appl Microbiol., 16(2):891-900

Antibiotic resistance is a universal problem in bacterial infections. Hence it gives high priority for new therapeutic methods to alternate conventional antibiotic treatment. Pigment production is one of the virulence characteristics of bacteria regulated by a quorum-sensing mechanism. Antiquorum sensing activities will not directly affect the viability of bacteria; however, they will reduce the pathogenicity of bacteria. Thereby it gives an adverse probability of the development of drug resistance. … Read more...

Chen X., Wu F., Sun B., Yang T.J. & Song H. (2022): Effects of nitrogen addition on bacterial community structure on bare rock and lichen covered rock surface of Leshan Giant Buddha, Acta Ecologica Sinica, 42

Atmospheric nitrogen (N) deposition may directly and indirectly affect the weathering process of stone cultural relics, but the relevant research is obviously insufficient. Therefore, this study took bare rock and lichen-covered rock as the research object and compared the effects of N addition treatments with different concentrations (N0 = 0 kg hm⁻² a⁻¹, N1 = 9 kg hm⁻² a⁻¹, N2 = 18 kg hm⁻² a⁻¹, N3 = 36 kg hm⁻² a⁻¹, and N4 = 72 kg hm⁻² a⁻¹) on the bacterial community. … Read more...

Watkinson A., Juckers M., D’Andrea L., Beckett P. & Spiers G. (2022): Ecosystem Recovery of the Sudbury Technogenic Barrens 30 Years Post-Restoration, Eurasian Soil Science, 55

Sudbury, Ontario, Canada experienced severe environmental degradation from intensive logging, mining, and smelting activities. Acidification and erosion of soils, as well as heavy metal deposition led to widespread vegetation mortality and the creation of 20 000 ha of barren and 80 000 ha of semi-barren land within the Sudbury region. Restoration processes, consisting of limestone application, fertilization, seeding, and tree planting, was initiated in 1978 and continues to present day. Although … Read more...

Furmanek Ł., Czarnota P. & Seaward M.R.D. (2022): Effects of lichen homogenates, mixtures of extracted substances and secondary metabolites on macromycetes – a critical review, SOUTH AFRICAN JOURNAL OF BOTANY, 149: 559-571

An analysis of data from experimental studies investigating the effect of powdered thalli, extracts and secondary metabolites from 25 lichen species on the growth dynamics of the mycelia of 36 species of macromycetes classified into different trophic groups (pathogens, saprotrophs and mycorrhizal fungi) is presented. Since various methods have been used to extract lichen substances, thereby preventing a direct comparison of results, a critical review was undertaken. The results of studies, depending … Read more...

Liu Y., Jia R., Yang H., Xing Z., Shi G. & Cui Z. (2022): Effects of sand burial caused by ant nests on soil microbial biomass, basal respiration, and enzyme activity in/under biocrusts in vegetated areas of the Tennger Desert, Land Degradation & Development, 33(10): 1596-1607

Sand burial of crusts, caused by ant burrowing, is a common phenomenon in desert landscapes, yet the potential impacts on soil processes are unknown. Three sand burial depths, 3.0–5.0 mm (deep burial), 1.0–1.5 mm (shallow burial), and 0 mm (control) affecting two dominant biocrusts (viz., cyanobacteria-lichen crusts and moss crusts) sampled in the moist and dry seasons were selected to explore this issue in two vegetation areas of the Tennger Desert. We collected 180 samples from biocrust … Read more...

Ball B.A., Convey P., Feeser K.L., Nielsen U.N. & Van Horn D.J. (2022): Environmental harshness mediates the relationship between aboveground and belowground communities in Antarctica, Soil Biology and Biochemistry, 164: 108493

Linkages between aboveground and belowground communities are a key but globally under-researched component of responses to environmental change. Given the logistical complications to studying these relationships, much of our knowledge derives from laboratory experiments and localized field studies which have so far yielded inconsistent results. Because environmental factors may alter relationships between above- and belowground communities, there is a need for broad-scale field studies testing these … Read more...

Ochirbat E., Samiya J., Tungalag M. & Purevdorj B. (2022): Establish of important habitats for dryland mountain biodiversity by their lichen species: (In case of Baraat mountain, Khujirt village, Mӧst sum, Khovd aimag), Mongolian Journal of Botany, 4(30): 24-39

The study of lichens, which are species sensitive to environmental changes, is of great use. As a result of our analysis of lichen biodiversity, it is shown that the habitats of dry grass meadows from the Baraat ridge of the village Hujirt-Bagh from the somon Must, Khuvd Aimak are extremely rare in the Altai-Sayan region and are important habitats for the gene pool and habitat of the rare genetic resources of lichens. As a result of the research, 52 species from 32 genera of 17 families were registered, … Read more...

Usnea longissima, fruticose lichen growing in the temperate region, is well known traditional medicinal herb and a reservoir of some unique secondary metabolites. Traditionally it has been commonly used as an antimicrobial agent for the treatment of ailments like tuberculosis, ulcers and skin diseases, etc. In our study, we evaluate antimicrobial, antiquorum sensing (QS) and antioxidant activity of Usnea longissima secondary metabolites extracted in acetone, methanol, and 70% hydroalcoholic solvents. … Read more...
