Ficko S.A., McClymont A., Haughland D.L. & Naeth M.A. (2023): Optimizing growth chamber conditions for maintaining Arctic lichen-dominated biocrusts - Restoration Ecology, 31(4): e13876 [9 p.]

Optimizing growth chamber conditions for Arctic lichen biocrusts will create new opportunities to assess and prioritize reclamation techniques given the challenges associated with conducting arctic field work. Our study is the first to examine growth chamber conditions for optimizing survival and growth of Arctic lichen biocrusts, as measured by changes in lichen cover. We assessed effects of substrate crossed with substrate depth, substrate sterilization, lichen inoculation and community composition, … 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...

McGrath C. (2023): Highlight: Gene Cluster Reshuffling Drives Natural Sunscreen Evolution in Lichens - Genome Biology and Evolution, 15(2): 1-2

A new study reveals that the evolution of sunscreen pigments in lichen-forming fungi has been governed by the reshuffling of existing enzyme genes and novel accessory genes into new gene clusters. Lichens are diverse and colorful organisms that can be found in nearly every environment on Earth, from the arctic tundra to tropical rainforests. Due to the wide variety of their phenotypes and propensity to be misidentified as plants, fungi, or mosses, lichens have long been poorly understood. Lichens … Read more...

Doyle E., Blanchon D., Wells S., de Lange P., Lockhart P., Waipara N., Manefield M., Wallis S. & Berry T.-A. (2023): Internal transcribed pacer and 16S amplicon sequencing identifies microbial species associated with asbestos in New Zealand - Genes, 14(3): 729 [12 p.]

Inhalation of asbestos fibres can cause lung inflammation and the later development of asbestosis, lung cancer, and mesothelioma, and the use of asbestos is banned in many countries. In most countries, large amounts of asbestos exists within building stock, buried in landfills, and in contaminated soil. Mechanical, thermal, and chemical treatment options do exist, but these are expensive, and they are not effective for contaminated soil, where only small numbers of asbestos fibres may be present … 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...

Ertz D. & Tehler A. (2023): New species of Arthoniales from Cape Verde with an enlarged concept of the genus Ingaderia - The Lichenologist, 55(1): 1-15

Three new species of Arthoniales are described from Cape Verde: Ingaderia dendritica, with ascomata formed of richly branched-dendroid lirellae and containing erythrin; Sparria caboverdensis, with small stroma-like ascomata and ascospores with 3–7 transverse septa; and Syncesia miesii, with an I− thallus, a tomentose hymenial disc, and a chemistry with fatty acids only. Phylogenetic analyses using nuLSU and RPB2 sequences reveal the placement of Fulvophyton sorediatum, Llimonaea occulta, L. sorediata … Read more...
