Aartsma P., Asplund J., Odland A., Reinhardt S. & Renssen H. (2020): The decline of alpine lichen heaths generates atmospheric heating but subsurface cooling during the growing season - Biogeosciences, 2024: 1-31

Lichen heaths are declining in abundance in alpine and arctic areas partly due to an increasing competition with shrubs. This shift in vegetation types might have important consequences for the microclimate and climate on a larger scale. The aim of our study is to measure the difference in microclimatic conditions between lichen heaths and shrub vegetation during the growing season. With a paired plot design, we measured the net radiation, soil heat flux, soil temperature, and soil moisture on an … URL EndNote PDF Read more...

Touchette D., Gostinčar C., Whyte L.G. & Altshuler I. (2023): Lichen-associated microbial members are prevalent in the snow microbiome of a sub-arctic alpine tundra - FEMS Microbiology Ecology, 99(12): fiad151

Snow is the largest component of the cryosphere, with its cover and distribution rapidly decreasing over the last decade due to climate warming. It is imperative to characterize the snow (nival) microbial communities to better understand the role of microorganisms inhabiting these rapidly changing environments. Here, we investigated the core nival microbiome, the cultivable microbial members, and the microbial functional diversity of the remote Uapishka mountain range, a massif of alpine sub-arctic … URL EndNote PDF Read more...

Lackner R.M., Ferron S., Boustie J., Le Devehat F., Lumbsch H.T. & Shibayama N. (2024): Unraveling a historical mystery: Identification of a lichen dye source in a fifteenth century medieval tapestry - Heritage, 7(5): 2370–2384

As part of a long-term campaign to document, study, and conserve the Heroes tapestries from The Cloisters collection at The Metropolitan Museum of Art, organic colorant analysis of Julius Caesar (accession number 47.101.3) was performed. Analysis with liquid chromatography– quadrupole time-of-flight mass spectrometry (LC-qToF-MS) revealed the presence of several multiply chlorinated xanthones produced only by certain species of lichen. Various lichen dye sources have been documented in the … URL EndNote PDF Read more...

Puolasmaa A. & Kuusisto I. (2024): Report of 27 lichenicolous fungi species and three genera new to Finland - Karstenia, 61(2): 9–19

We studied systematically herbaria lichen specimens collected from Finland and from former Finnish parts of Russia to detect lichenicolous fungi. In total, 3355 lichen specimens were found with lichenicolous fungi from 160 taxa. We report here 27 species and three genera that are new to Finland. Three of these, Cercidospora epithamnolia, Cyclothyrium sp. and Roselliniella stereocaulorum, are reported as also new to Scandinavia. Three taxa are reported from a new host.

Farkas E., Xu M., Muhoro A.M., Szabó K., Lengyel A., Heiðmarsson S., Viktorsson E.Ö. & Ólafsdóttir E.S. (2024): The algal partnership is associated with quantitative variation of lichen specific metabolites in Cladonia foliacea from Central and Southern Europe - Symbiosis, 92: 403–419

Lichen specific metabolites (LSMs) have interesting biological activities and quantitative variations may be present intraspecifically. For example, variations in medullary fumarprotocetraric acid (FA) and cortical usnic acid (UA) were observed in the lichen Cladonia foliacea, but the mechanism of variation is not well understood. The current study aimed to characterise the quantitative variation of FA and UA and to investigate the association between lichen metabolite content and ecological / biological … URL EndNote Read more...

Pushpavathi D. & Krishnamurthy Y.L. (2024): Study on endolichenic fungal assemblage in Parmotrema and Heterodermia lichens of Shivamoga, Karnataka - Molecular Biological Reports, 51: 549 [14 p.]

Background: Lichen is a symbiotic association of algae and fungi, recognized as a self-sustaining ecosystem that constitutes an indeterminant number of bacteria, actinomycetes, fungi, and protozoa. We evaluated the endolichenic fungal assemblage given the dearth of knowledge on endolichenic fungi (ELFs), particularly from part of the Central Western Ghats, Karnataka, and conducted a phylogenetic analysis of xylariaceous fungi, the most diversified group of fungi using ITS and ITS+Tub2 gene set.

Zakhozhiy I.G. & Shelyakin M.A. (2024): Accumulation and localization of metals in lichen thallus under conditions of dust pollution during open mining of boxite deposits - Russian Journal of Ecology, 55: 32–41

We studied the accumulation and localization of metals in the foliose lichens Lobaria pulmonaria, Hypogymnia physodes, and Peltigera aphthosa, living in the impact zone of the Sredne-Timansky bauxite mine. A significant accumulation of Al (16–19 g/kg), Fe (16–20 g/kg), and Ti (0.3–0.7 g/kg) by thalli was revealed. From 29 to 82% of the total content of these metals is localized in dust particles weakly attached to the surface of the thalli. The total proportion of intra- and extracellularly … URL EndNote PDF Read more...

Boonpeng C., Pischom M., Butrid P., Noikrad S. & Boonpragob K. (2024): Laboratory and field measurements of water relations, photosynthetic parameters, and hydration traits in macrolichens in a tropical lower montane rainforest in Thailand - J Plant Res, 2024: 3-18

Ecophysiological studies of lichens in tropical Asia are rare, and additional studies can increase the understanding of lichen life in this region. The main aim of this study was to observe the relationships between water availability and photosynthetic parameters, as well as hydration trait parameters, in macrolichens during the rainy and dry seasons in a tropical forest. A total of 11 lichen species growing in a lower montane rainforest in Thailand were collected and studied. The results clearly … URL EndNote PDF Read more...

Condon L.A., Bradford J.B. & Coates P.S. (2024): Biological soil crusts are more prevalent in warmer and drier environments within the Great Basin ecoregion: implications for managing annual grass invasion - Restoration Ecology, n/a(n/a): e14150

Biological soil crusts (biocrusts) can thrive under environmental conditions that are stressful for vascular plants such as high temperatures and/or extremely low moisture availability. In these settings, and in the absence of disturbance, cover of biocrusts commonly exceeds cover of vascular plants. Arid landscapes are also typically slow to recover from disturbance and prone to altered vegetation and invasion by exotic species. In the sagebrush ecosystems, cover of annual, exotic, invasive grasses … URL EndNote PDF Read more...
