Vasarri M., Ponti L., Degl’Innocenti D. & Bergonzi M.C.C. (2022): Usnic acid-loaded polymeric micelles: An optimal migrastatic-acting formulation in human SH-SY5Y neuroblastoma cells - Pharmaceuticals, 15(10): 1207 [16 p.]

Usnic acid (UA) is one of the most abundant and common metabolites of lichens, known for its numerous pharmacological properties. Nevertheless, it presents some criticalities that severely limit its use in therapy: poor solubility in water and significant hepatotoxicity. Soluplus and Solutol HS15 and D-α-Tocopherol polyethylene glycol 1000 succinate (TPGS) were employed to develop polymeric micelles (UA–PM). The chemical and physical properties of the system were characterized, including the size, … Read more...

Zhang T., Zhu X., Vizzini A., Li B., Cao Z., Guo W., Qi S., Wei X. & Zhao R. (2022): New insights into lichenization in Agaricomycetes based on an unusual new basidiolichen species of Omphalina s. str. - Journal of Fungi, 8(10): 1033 [11 p.]

The genus Omphalina is an ideal genus for studying the evolutionary mechanism of lichenization. Based on molecular phylogeny using ITS and nuLSU sequences by means of Bayesian and maximum likelihood analyses and morphological examination, combining the existence of green algae in basidiomata stipe and a Botrydina-type vegetative thallus, we described a bryophilous new basidiolichen species, Omphalina licheniformis, from a residential area of Jiangxi Province, China. This finding of unusual new basidiolichen … Read more...

Robison A., Baugh M., Muggia L. & Leavitt S.D. (2022): Fruticose lichen communities at the edge: Distribution and diversity in a desert sky island on the Colorado Plateau - Conservation, 2(4): 550–565

Subalpine habitats in sky islands in the Southwestern USA are currently facing large-scale transformations. Lichens have widely been used as bioindicators of environmental change. On the Colorado Plateau, fruticose lichens occur in patchy, disconnected populations, including unique lichen-draped conifer sites in subalpine forests in the La Sal Mountains in southeastern Utah. Here, we document the distribution and fungal diversity within these lichen communities. We find that lichen-draped conifer … Read more...

Belguidoum A., Lograda T. & Ramdani M. (2022): The lichen flora on Quercus in the Tamentout Forest of Algeria - Phytotaxa, 566(2): 200–208

Lichens are major components of forest ecosystems. However, their accurate identification at species level is often difficult, especially in poorly investigated areas. The objective of this study is an inventory of epiphytic lichens in the Tamentout Forest on three types of phorophytes, Quercus faginea, Q. suber and Q. ilex. In this region, 68 epiphytic lichen species have been identified, belonging to 23 families and 36 genera. The specific richness on the three phorophytes was different. Quercus … Read more...

Carrillo W., Calva J. & Benítez Á. (2022): The use of bryophytes, lichens and bromeliads for evaluating air and water pollution in an Andean city - Forests, 13(10): 1607 [11 p.]

Air and water pollution are global environmental problems; thus, bioindicators have become important tools for monitoring various pollutants, including metals and metalloids. Parmotrema arnoldii (Du Rietz) Hale and Tillandsia usneoides L. were evaluated as indicators of heavy metals in the air and Platyhypnidium aquaticum A. Jaeger and Marchantia polymorpha L. as indicators of heavy metals and a metalloid in water. The concentrations of cadmium (Cd), lead (Pb), copper (Cu), manganese (Mn) and zinc … Read more...

Yang Q., Hollinger J., Leavitt S.D. & Wei X. (2022): Two new species and two new records of the lichen-forming fungal genus Peltula (Ascomycota: Peltulaceae) from China - Biology, 11(10): 1518 [14 p.]

In this study, two new species, Peltula confusa Q.X. Yang & X.L. Wei, sp. nov., growing in a dry microenvironment within a semi-humid area, and Peltula subpatellata Q.X. Yang & X.L. Wei, sp. nov., occurring in arid and semi-arid regions, are described. In addition, two species, P. polyspora (Tuck.) Wetmore and P. obscuratula (Nyl.) Poelt ex Egea, are recorded for the first time in China. All four species are described based on morphological, anatomical and molecular data. Peltula confusa is characterized … Read more...

Ureña-Vacas I., González-Burgos E., Divakar P.K. & Gómez-Serranillos M.P. (2022): Lichen extracts from cetrarioid clade provide neuroprotection against hydrogen peroxide-induced oxidative stress - Molecules, 27(19): 6520 [16 p.]

Oxidative stress is involved in the pathophysiology of many neurodegenerative diseases. Lichens have antioxidant properties attributed to their own secondary metabolites with phenol groups. Very few studies delve into the protective capacity of lichens based on their antioxidant properties and their action mechanism. The present study evaluates the neuroprotective role of Dactylina arctica, Nephromopsis stracheyi, Tuckermannopsis americana and Vulpicida pinastri methanol extracts in a hydrogen peroxide … Read more...

Valenzuela C., Leiva D., Carú M. & Orlando J. (2022): Prediction of the metabolic functions of nitrogen, phosphorus, and sulfur cycling bacteria associated with the lichen Peltigera frigida - Microbiology, 91(5): 604–610

Lichens are currently interpreted as complex self-sustaining ecosystems formed by the interaction of the primary symbionts and other microorganisms. These microorganisms, which colonize the surface of lichen thalli, could be crucial actors in nutrient cycling. Here, we used PICRUSt2 to predict and compare the potential functions of bacteria closely associated with Peltigera frigida thalli and their substrates. We found that these bacteria could potentially transform organic and inorganic molecules … Read more...

Mikhailova I.N. (2022): Dynamics of distribution boundaries of epiphytic macrolichens after reduction of emissions from a copper smelter - Russian Journal of Ecology, 53(5): 335–346

[English translation of Russian Text published in Ekologiya, 2022, No. 5, pp. 321–333] Natural recovery of forest ecosystems after the termination of impacts caused by emissions from large industrial enterprises gives a clue to their sustainability mechanisms. However, the lack of data on dif- ferent ecosystem components, natural zones, and emission sources makes it impossible to identify general patterns of restorative successions. This paper examines the distribution and abundance dynamics … Read more...

Yarzábal L.A., Buela L., de los Ríos A., Peláez D., Romero M., Espinoza F., Torres A.S., Medina G.M., Landi J.G. & Tapia M.V. (2022): Biological deterioration of an Inca monument at high altitude in the Andean range: A case study from Ingapirca’s Temple of the Sun (Ecuador) - Heritage, 5(3): 2504–2518

Scientific studies concerning the causes and consequences of the biodeterioration of stone monuments located at high altitudes in permanently cold, mountainous regions are scarce. For that reason, this study aimed to detect and identify the bacteria involved in the deterioration of this type of monument. To achieve this goal, we focused on the most important archeological Inca site in the Ecuadorian Andes: Ingapirca’s Temple of the Sun, built approximately 500 years ago at 3.100 m.a.s.l. We first … Read more...
