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...

Lorenz C., Arena C., Vitale E., Bianchi E., Poggiali G., Alemanno G., Benesperi R., Brucato J.R., Garland S., Helbert J., Loppi S., Lorek A., Maturilli A., Papini A., de Vera J.-P. & Baqué M. (2024): Resilience of Xanthoria parietina under Mars‑like conditions: photosynthesis and oxidative stress response - Planta, 259: 25 [8 p.]

Xanthoria parietina (L.) Th. Fr. is a widespread lichen showing tolerance against air pollutants and UV-radiation. It has been tested under space-like and Mars-like conditions resulting in high recovery performances. Hereby, we aim to assess the mechanisms at the basis of the thalli resilience against multiple space stress factors. Living thalli of X. parietina were exposed to simulated Martian atmospheric conditions (Dark Mars) and UV radiation (Full Mars). Then, we monitored as vitality indicator … Read more...

Fjelde M.O., Timdal E., Haugan R. & Bendiksby M. (2024): Paraphyly and cryptic diversity unveils unexpected challenges in the “naked lichens” (Calvitimela, Lecanoromycetes, Ascomycota) - Molecular Phylogenetics and Evolution, 190: 107944 [16 p.]

Molecular phylogenetics has revolutionized the taxonomy of crustose lichens and revealed an extensive amount of cryptic diversity. Resolving the relationships between genera in the crustose lichen family Tephromelataceae has proven difficult and the taxon limits within the genus Calvitimela are only partly understood. In this study, we tested the monophyly of Calvitimela and investigated phylogenetic relationships at different taxonomic levels using an integrative taxonomic approach. We performed … 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...

Svanberg I. & Ståhlberg S. (2024): Peasant food provision strategies and scientific proposals for famine foods in eighteenth-century Sweden - Gastronomy, 2(1): 18–37

The peasant diet during the Little Ice Age in Sweden was mainly grain-based (bread, gruel, and porridge), and the country was heavily dependent on grain imports to meet the population’s needs for food. During the eighteenth century in particular, when famines were frequent following failed harvests, Swedish peasants utilized a range of locally available resources to survive. Bark bread made of cambium (phloem) from Pinus sylvestris was, for example, commonly used as famine food. Scientists of the … Read more...

He Z., Naganuma T. & Melville H.I.A.S. (2024): Bacteriomic profiles of rock-dwelling lichens from the Venezuelan Guiana Shield and the South African Highveld Plateau - Microorganisms, 12(2): 290 [18 p.]

Lichens are not only fungal–algal symbiotic associations but also matrices for association with bacteria, and the bacterial diversity linked to lichens has been receiving more attention in studies. This study compares the diversity and possible metabolism of lichen-associated bacteria from saxicolous foliose and fruticose taxa Alectoria, Canoparmelia, Crocodia, Menegazzia, Usnea, and Xanthoparmelia from the Venezuelan Guiana Shield and the South African Highveld Plateau. We used DNA extractions … 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...

Viola A., Newington N., Riley J., Selva S. & Proulx L. (2024): Bursting the stubble bubble: citizen scientists measure ecological continuity near Goldsmith Lake, Nova Scotia using calicioid lichens and fungi - Evansia, 41(1): 9–18

In an effort to protect a forest on provincial land near Goldsmith Lake in Annapolis County, Nova Scotia, from timber harvest operations, a group of citizen scientists began documenting the biodiversity of the area. In December 2022, the group invited Dr. Steven Selva, a lichenologist specializing in calicioid lichens and fungi, to visit and teach them how to locate and collect calicioid specimens. We found 27 calicioid species, one of which was new to the Maritimes, providing additional evidence … Read more...

Zhang Y., Yin Y., Wang L., Printzen C., Wang L. & Wang X. (2024): Two new species of Rhizoplaca (Lecanoraceae) from Southwest China - MycoKeys, 101: 233–248

In this study, two new species, Rhizoplaca adpressa Y. Y. Zhang & Li S. Wang and R. auriculata Y. Y. Zhang, Li S. Wang & Printzen, are described from Southwest China, based on their morphology, phylogeny and chemistry. In phylogeny, the two new species are monophyletic, and sister to each other within Rhizoplaca chrysoleuca-complex. Rhizoplaca adpressa is characterized by its placodioid and closely adnate thallus, pale green and heavily pruinose upper surface, narrow (ca. 1 mm) and white free margin … Read more...
