Varga N., Lőkös L. & Farkas E. (2023): Contributions to the lichen-forming and lichenicolous fungi of the Aggtelek National Park (NE Hungary) - Studia Botanica Hungarica, 54: 155–174

Rece nt lichenological investigations add new and noteworthy records of lichen-forming and lichenicolous fungi to the Aggtelek National Park, especially from the Szalonna-Karst region (Mt Esztramos near Bódvarákó, Mt Szár-hegy near Martonyi). Altogether 64 records of 38 species of lichen-forming fungi and 13 species of lichenicolous fungi are presented and annotated. Agon imia globulifera, Lecanora compallens and Th alloidima physaroides have been reported from the Aggtelek National Park … Read more...

Mühlbauer L.K., Zavattoni G., Virtanen R., Grube M., Weber B. & Clark A.T. (2023): Arduinos in the wild: A novel, low-cost sensor network for high-resolution microclimate monitoring in remote ecosystems - Ecological Solutions and Evidence, 4: e12255 [14 p.]

The importance of microclimate conditions is becoming increasingly recognised in ecological research, especially as they can differ widely from macro- and mesoclimate. Effective measurement of microclimate variability in heterogeneous field conditions requires measurements from a large number of sensors, ideally sampling across both small and large scales, which necessitates the development of cost-effective sensor networks. Here, we develop an environmental microcontroller (EMU) sensor network … Read more...

Mendili M., Khadhri A., Sabatini F., Degano I. & Aschi-Smiti S. (2023): Parietin, the vibrant natural dye in Xanthoria parietina - Chemistry and Biodiversity, 21: e202301357 [11 p.]

The use of natural dyes in several areas is regulated by current European and non-European legislation, due to various problems with synthetic dyes. The analysis revealed that the lichen studied: Xanthoria parietina has potential natural dye sources and provides bright colors for extraction solvents. Furthermore, dyed wool and toile fabric have good fastness properties in ammonia fermentation and boiling water, both with and without mordants. The sample dyes with Xanthoria parietina were characterized … Read more...

Boutabia L., Menaa M. & Telailia S. (2023): Corticolous lichen communities in Algerian climax forests - African Journal of Ecology, 61: 1030–1037

The great extension of forests in the Djebel El Ghorra massif of El Kala National Park (north-eastern Algeria) allowed us to recognise three distinct forest formations: cork oak stands (Quercus suber), zeen oak stands (Quercus canariensis) and mixed oak (Quercus suber and Quercus canariensis) forest. Their peculiarities showed ideal ecological characteristics for the colonisation of corticolous lichens the two phorophytes. The three forest formations were sampled between 2017 and 2022. The identification … Read more...

Wang Y., Li R., Wang D.,Qian B., Bian Z., Wei J., Wei X. & Xu J.-R. (2023): Regulation of symbiotic interactions and primitive lichen differentiation by UMP1 MAP kinase in Umbilicaria muhlenbergii - Nature Communications, 14: 6972 [13 p.]

Lichens are of great ecological importance but mechanisms regulating lichen symbiosis are not clear. Umbilicaria muhlenbergii is a lichen-forming fungus amenable to molecular manipulations and dimorphic. Here, we established conditions conducive to symbiotic interactions and lichen differentiation and showed the importance of UMP1 MAP kinase in lichen development. In the initial biofilm-like symbiotic complexes, algal cells were interwoven with pseudohyphae covered with extracellular matrix. After … Read more...

Baradaran B., Saadatmand S., Haji Moniri M. & Asri Y. (2023): New records of crustose lichen species for Iran and Asia - Acta Biologica Szegediensis, 67(1): 55–61

The Khorasan-Razavi Province in northeastern Iran boasts a diverse lichen flora, fostered by its climatic diversity and extensive calcareous substrates, which provide an ideal habitat for crustose saxicolous lichens. However, the distribution of these lichens in this province has remained inadequately explored. Thus, this study aims to conduct a taxonomic investigation of crustose saxicolous lichens within this area. Between 2018 and 2019, we employed survey methods to collect 436 rock substrates … Read more...

Zhang W., Ran Q., Li H. & Lou H. (2024): Endolichenic fungi: a promising medicinal microbial resource to discover bioactive natural molecules—an update - Journal of Fungi, 10(2): 99 [49 p.]

Lichens are some of the most unique fungi and are naturally encountered as symbiotic biological organisms that usually consist of fungal partners (mycobionts) and photosynthetic organisms (green algae and cyanobacteria). Due to their distinctive growth environments, including hot deserts, rocky coasts, Arctic tundra, toxic slag piles, etc., they produce a variety of biologically meaningful and structurally novel secondary metabolites to resist external environmental stresses. The endofungi that live … Read more...

Herring B. (2024): Status survey of the federally endangered Perforate Reindeer Lichen (Cladonia perforata) throughout its known range in Florida - Castanea, 88(2): 241–279

A range wide status survey of the perforate reindeer lichen (Cladonia perforata) was performed by revisiting known extant and historical sites and searching for new populations. Size of each popula- tion was determined and the extent of invasive plant species in the vicinity of Cladonia perforata was also documented. The data was used to update the global and state NatureServe conservation status rank of this species and provide the current information to the United States Fish and Wildlife Service … Read more...

Shamblin Z. & Puppo P. (2024): Developing a 3D digitization protocol at the Marshall University Herbarium using free, open-source 3D reconstruction software - Castanea, 88(2): 191–204

Herbarium specimen digitization and transcription initiatives have led to revitalized use of plant collections making them more accessible than ever. Most digitization is done by producing 2D images of herbarium sheets; however, herbaria also include 3D collections such as fungi, mosses, and dry fruits, among others. Here we present a 3D digitization protocol developed at the Marshall University Herbarium (MUHW) using free photogrammetry software. We tested four freely available software applications, … Read more...

Cicardi M., Bernasconi D., Martire L., Pastero L., Caneva G. & Favero-Longo S.E. (2024): Centimetric circular areas uncolonized by microbial biofilms (CUMBs) on marble surfaces and insights on a lichen-related origin - International Biodeterioration and Biodegradation, 186: 105681 [13 p.]

This study investigated the poorly known phenomenon of Centimetric circular areas Uncolonized by Microbial Biofilms (CUMBs) which is frequently observed on natural and heritage stone surfaces displaying widespread lithobiontic colonization. In order to unveil a possible relationship with past lichen colonization, analyses were carried out on the distribution, morphometry, physical and mineralogical properties, and microscopic features of CUMBs on the marble surfaces of a balustrade in the Garden … Read more...
