Meyer A.R., Valentin M., Liulevicius L., McDonald T.R., Nelsen M.P., Pengra J., Smith R.J. & Stanton D. (2022): Climate warming causes photobiont degradation and carbon starvation in a boreal climate sentinel lichen - American Journal of Botany, 110: e16114 [16 p.]

Premise: The long-term potential for acclimation by lichens to changing climates is poorly known, despite their prominent roles in forested ecosystems. Although often considered “extremophiles,” lichens may not readily acclimate to novel climates well beyond historical norms. In a previous study (Smith et al., 2018), Evernia mesomorpha transplants in a whole-ecosystem climate change experiment showed drastic mass loss after 1 yr of warming and drying; however, the causes of this mass loss were … Read more...

[in Chinese with English abstract and description of a new taxon] The lichen-forming genus Diploschistes belongs to Ascomycota, Lecanoromycetes, Ostropomycetidae, Graphidales, Diploschistaceae. This genus includes 48 crustose species worldwide, and is confirmed as monophyletic group. Based on morphological, anatomical and chemical observation combined with phylogenetic analysis of ITS, a new species of Diploschistes, D. viridis (referring to subg. Diploschistes), is found and described … Read more...

Miral A., Jargeat P., Mambu L., Rouaud I., Tranchimand S. & Tomasi S. (2022): Microbial community associated with the crustose lichen Rhizocarpon geographicum L. (DC.) living on oceanic seashore: A large source of diversity revealed by using multiple isolation methods - Environmental Microbiology Reports, 14: 856–872

Recently, the study of the interactions within a microcosm between hosts and their associated microbial communities drew an unprecedented interest arising from the holobiont concept. Lichens, a symbiotic association between a fungus and an alga, are redefined as complex ecosystems considering the tremendous array of associated microorganisms that satisfy this concept. The present study focuses on the diversity of the microbiota associated with the seashore located lichen Rhizocarpon geographicum, … Read more...

Gheza G., Nascimbene J., Barcella M., Bracco F. & Assini S. (2022): Epiphytic lichens of woodland habitats in the lower Ticino river valley and in the “Bosco Siro Negri” Integral Nature State Reserve (NW Italy) - Natural History Sciences. Atti Soc. it. Sci. nat. Museo civ. Stor. nat. Milano, 9(2): 7–18

Epiphytic lichens were surveyed in the “Bosco Siro Negri” Integral Nature State Reserve (province of Pavia, Lombardy, NW Italy), which hosts a well-preserved fragment of oak-elm flood-plain forest (Natura 2000 Habitat 91F0). The core woodland fragment hosted only four species on the tree boles, i.e. Lepraria finkii plus the forest specialists Coenogonium pineti, Diarthonis spadicea, and Opegrapha vermicellifera. An additional eight nitro- and photophytic species … Read more...

Karagoz Y. & Karagoz B. (2022): Lichens in Pharmacological Action: What Happened in the Last Decade? - Eurasian Journal of Medicine, 54: S195-S208

Lichens are a unique group of organisms, which can produce compounds that are named secondary metabolites and rarely or are not produced in other organisms. Lichens possess pharmacological actions related to their secondary metabolites. Our knowledge of lichens and their pharmacological actions rapidly increases as new technologies and devices, which facilitate the investigation of the chemical profile and biological activities of lichens, are introduced and become more readily available. In addition, … Read more...

Halıcı M.G. & Kahraman Yiğit M. (2022): Rinodina gennarii Bagl., a new record of lichenized fungi for Antarctica - Czech Polar Reports, 12(2): 155–159

In a project aiming to determine the lichen biodiversity of James Ross Island which is located in the NE Antarctic Peninsula, 3 specimens growing on basaltic rocks were identified as Rinodina gennarii, a cosmopolite bipolar species which was never reported from Antarctica. This species is characteristic by having Dirinaria-type ascospores lacking a distinct torus and swelling around the septa in KOH. Detailed morphological and anatomical properties of this species along with photographs based on … Read more...

Hájek J., Puhovkin A., Giordano D. & Sekerák Jr. J. (2022): What does critical temperature tell us about the resistance of polar lichens to freezing stress? Applicability of linear cooling method to ecophysiological studies - Czech Polar Reports, 12(2): 246–255

Lichens from polar regions are well adapted to low temperature and considered cryoresistant. However, interspecific differences in their cryoresistance exist according to the degree of their adaptation and severity of the environment. In our study, we applied linear cooling technique in order to evaluate the interspecific differences in several lichen species. Thalli segments of Umbilicaria antarctica, Nephroma antarctica, Placopsis contortuplicata and Lasallia pustulata were exposed to the cooling … Read more...

Manová A., Hýžová B., Darriba Canora D., Castrillo Antolin A. & Dufková K. (2022): Vitality and growth rate of agar plate-cultivated Antarctic microautotrophs: Analysis of PSII functioning by chlorophyll fluorescence parameters - Czech Polar Reports, 12(2): 269–279

In our study, we focused on the growth of three different microautotrophs isolated from Antarctic lichens (Placopsis contortuplicata, Solorina spongiosa) and cryptoendolithic algal vegetation. The isolates were purified and inoculated on agar plates, Bold´s Basal Medium (BBM). The growth of the cultures and the markers of physiological (photosynthetic) activity were monitored by chlorophyll fluorescence in 1 week intervals for 3 months after inoculation. For the assessment of photosynthetic activity, … Read more...

[in Mongolian with English abstract: ] 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 … Read more...
